MVVM Platform Composer

2010-12-21T11:16:00.000Z

In my 'spare' time I'm developing a WPF pure MVVM platform composer, at the moment I have learned and improved many things like datatemplates nesting to create itemscontrols inside itemscontrols.
The idea is to create XMLs for XNA WP7 levels games. The first game I'll do is a shoot'em up with a new kind of levels, mixing different missions with achievements.

Note: The enemies are a really old version.

Great indie games are coming :).

Tip #1 MVVM Delegate Command with an ObservableCollection

2010-09-01T09:22:00.000Z

First of all I get the DelegateCommand from the .toolbox courses (I encourage you to download them and find it).

Using this DelegateCommand wich we bind to a button Command for instance (I always add CommandParameter in xaml too, (in order to work fine).

Now my layoutroot datacontext viewmodel has the following property:

private ObservableCollection _sales;
public ObservableCollection Sales
{
get { return _sales; }
set
      {
         _sales= value;
         NotifyPropertyChanged("Sales");
         }
        }

And now (in this case is a WPF application, in case you use SL I recommend you to use PagedViewCollection), I instance the command in the constructor:

PaidCommand = new DelegateCommand()
{
ExecuteCommand = () =>
   {
      bw = new BackgroundWorker();
      bw.RunWorkerCompleted += (s, e) =>
        {
          NotifyPropertyChanged("Sales"); //#1
        };
      bw.DoWork += (s1, e1) =>
        {
           _sales= DM.GetSales(_date1, _date2); //#2
        };
      bw.RunWorkerAsync();
    }
};

In #2 we process every lines of code we want filling our private fields and when it's finished we publish
simply Notifying them #1 (In my case I have a datagrid with ItemsSource = {Binding Sales})

I hope it helps you (I like this way to do).

And now just a question if any one knows , for other classes I would like to define. Let's suppose a not MVVM environment

Button1.OnClick += (s,e) =>

{

...

};

Do you know a way to remove inside the ... the previous delegates like the old way:

Button1.OnClick -= OnButton1Clicked;

Open asp.net crystal report from Silverlight 4 - Report with List T and List S subreport

2010-05-26T12:50:00.003Z

1.- The sources: (To do not have CR errors)

Let's suppose (I like when it works) create a Crystal Report with a Subreport and the source are two List and List.

How can I set the sources.
A.- Create a new report in the project.
B.- Set the following as sources (Both the main and the child one):

C.- Now you add the subreport to the main report:

D.-And add only the child class.
E.- Now in the main Report from database expert remove the child class because we needed it only to be able to add the child report.

In this moment we have defined the design of the report. Now by code we will fill it in the aspx:

E.- We add the viewer and a source

F.- In the .cs we add the following: (Create the templates, depending on the version you will need it)

#region Create XML Templates
XEvento xe = new XEvento();
xe.Cliente = "";
xe.Comercial = "";
xe.Fecha = new DateTime(2010, 10, 10);
xe.SerializeObj(XEvento.ItemsFile);

XHistorico xh = new XHistorico();
xh.Nombre = "Prueba";
xh.Fecha = new DateTime(2010, 10, 10);
xh.Detalle = "Esto es otra prueba";
xh.SerializeObj(XHistorico.ItemsFile);
#endregion

G.- Fill the two lists with your data.
H.- On Page_Load:
this.CrystalReportSource1.ReportDocument.Subreports[0].SetDataSource(xhs);
this.CrystalReportSource1.ReportDocument.SetDataSource(xes);

And that's all the first part in the asp.net

2.- In a method in the silverlight:

private void BPrint_Click(object sender, RoutedEventArgs e)

{

            HtmlPopupWindowOptions options = new HtmlPopupWindowOptions()

{

                Directories = false,

                Location = false,

                Menubar = false,

                Status = false,

                Toolbar = false,

};

            HtmlPage.PopupWindow(new Uri("http://localhost:51694/Reporting.aspx?Fecha=" + DP.SelectedDate.Value.Date.ToShortDateString().Replace('/','.') ), "_blank", options);

}

3.- In the Page_Load in the asp.net capture the parameter:

this.TextBox1.Text = HttpContext.Current.Request.Params["Fecha"];

Now you have to set it as a parameter of the crystal report and that's all.

Tip: Gimp remove red lines

2010-03-15T12:23:00.000Z

If you have scracths, dust or anything that makes your pictures with lines or bands, apply the filter disparasite, check adaptative, uncheck recursive, radius =1,black level = -1, white level = 256
And that's all

Tip for WPF Mess Resizing

2010-03-09T12:27:00.000Z

When you begin to add containers and controls inside a WPF and you resize the form, you realize that the mess that happens, what you should do to keep the form is change the main grid container to a canvas, and you will have the control again.

Context Menu - Send to... Boss

2010-01-31T11:12:00.000Z

Suppose you have to send many times to your account or to your boss attachments from your computer. Well, if you have MS Outlook 2007 there's a way adding in two big steps, creating a new form in Outlook and the second creating a shortcut in the sendto folder, so let's go

A.- Creating the new form (template) from a standard message form:

1.- Have installed Outlook 2007
2.- Open it.
3.- Tools -> Forms -> Design Form
4.- Choose Message from the List
5.- Click on the To Text Box
6.- Click on the Properties icon
7.- Choose the 'Value'
8.- Set Initial value checked
9.- Set a value between ""
10.- Check automatic... to check it works
11.- Publish -> Publish Form As
12.- In Look In: Choose "Personal Forms Library"
13.- Display Name "Boss"
14.- Now Click Publish
15.- Close and save the changes

B.- Creating a new shortcut:
1.- Run: "shell:sendto"
2.- Copy the shortcut of Outlook to send to
3.- Right click - properties
4.- in Start in, after the last " add : /c IPM.note.Boss /a "%1" where Boss is the name of the form
5.- Click ok and rename the shortcut to Boss and that's done.

I will add some screenshots to have a better idea.

8,16,32 GB Flash drives review

2008-10-23T12:19:00.002Z

Due to I have bought some multimedia devices (1080i mkv usb player) and the files from my hard disk takes a lot of time copying and reading in usual flash drives. The HD files with huge Mbps from my Canon HV20 are actual problems I try to avoid. I have made a chart from multiples sources, reviews and prices because I have not found any benchmark of this kind. I have not included Buffalo neither Transcend due to I have not found any decent review or benchmark. Might be Buffalo has a chance, who knows. Well, take a look:

Take care that I have done from Internet sources, I am not responsible of the data showed before, It's only sharing information. Those are my conclusions:

16GB:After analyzing the scores (Read1+Read2+Write1+Write2)/Price, we take care that a 16 GB is the best one (Patriot 8GB can be the first one), and as you see it has a really interesting price. As you see the OCZ Rally2 16GB has the half speed on writing so there is no doubt.

32GB:About 32GB now OCZ wins, I am not sure why the writing speed vs the 16GB is so huge. Of course I haven't the flash drives to test them, but the technology could have changed. In case of doubt, followint this is Patriot again.

08GB:In the 8GB flash drives, I am sure that Patriot wins, then Corsair Survivor GT (may be the Voyager GT too), and after the Sandisk, which is not typical in this kind of charts. Well, I hope the analysis helps you because now I know that I have to buy the Patriot 16GB, because 8GB could be little today.

Preparing a new article

2008-10-17T12:31:00.002Z

After so much time, I have a new idea for an article that is not only visually great, it has extreme functionality. The idea is a new fresh styles and UI for making forums, because the typical style of the forums when they grow is unhandle, so my new article will be a silverlight developed forum in a new mind style.
I hope have time enough to give it form and publish it before the end of the year, I am not to telling you more details to do not have copiers. But be sure a great article is coming.

If you have not seen my articles, take a look here. Have a nice weekend

Computer madness

2008-10-08T10:43:00.002Z

As you know I do not usually add contents like the following, but this is so sci-fi:

The SDD is deprecated, yes it's true. The Blu-Ray, the CPUs, the GPU is deprecated and all the 1st level future is old-fashioned. Here I show you the last amazing science-fiction that you could never imagine. A PCI-Express SSD that reads a photoshop file of 750 MB in 26 seconds, and 256 videos playing on the screens as piece of cake.

Here is the sci-fi-pci-sdd. In a few years we will see a CPGPU of 300x300mm processor with 16 GB SSDRAM 500 GB SSDISK. That means all inside the processor.

Proyecto interesante de aprendizaje por superación

Webtablet

2008-07-22T10:29:00.003Z

Maybe you hate being printing pdfs, and webs to take a look them at night, or reading in your laptot, and seeing that a tablet pc costs more than $2500, today I have seen an interesting project: techcrunchit webtablet I have add some specifications:

harddisk OCZ Rally2 8GB USB or A-Data 4GB Compact Flash
motherboard MX800LX2D http://www.bcmcom.com/bcm_product_mx800lx2.htm
memory A-DATA 1GB 184-Pin
screen ?

the motherboard is the latest fanless I have find on the web, and it can be connected directly to 12V.

I think two possibilities,

1.- use a USB as a hardisk (I do not know if the bios can boot from USB)
with a wireless module on the CF module.
2.- use a USB wifi module with a CF hardisk.

Both kind of wifi modules has antenna conector, so is possible to extend the wifi range.

I think the biggest issue in this project is a cheap 800x600 or 1024x768 SVGA panel up to 100$ with A4 size, I have found this kits:

12.1'':
http://www.mouser.com/Search/ProductDetail.aspx?qs=SXvQijT3Ep8DSdtY4%252boUSg%3d%3d
http://www.fujitsu.com/downloads/MICRO/fcai/touchpanels/7_wire_standard_ds_rohs.pdf

59$ the 12.1 model

15'': http://www.mouser.com/Search/ProductDetail.aspx?qs=3gJN1c9na9e4AD7syQ1Zww%3d%3d
with touch for 123$

SO IS POSSIBLE, if you know interesting info reply in the forum

New style

2008-06-06T14:02:00.002Z

Well this noon I was updating the blog and I saw there was a grey layer over the blog and it only appeared on the IE (as always), the issue is inside the script of analytics because when I remove it, all works, but I have to use it, so I decide trying changing the template, after hours I found this interesting one, so now I can continue programming. I have added a visit counter too, let's see how it works

40 pages of bitmap bgs

2008-06-06T07:17:00.002Z

Hi everyone, I've seen new visits these days, might be people is looking for the videos I promised. I'm not having problems I do not have enough time. What I want first is to explain the whole NDS graphic system in a book, at the moment I have 40 pages only up to bitmap bgs and now I have to add the tiles maps and sprites. I think is really complete and very well presented. I have made devkitprojects for each example so understand me, it tooks time, but I think is necessary because I thinks there's a huge lack in this matter and old code. I'll try to put a video of the bitmap bg progress this weekend but I can't promise anything.

P.S. Hey I have just received the BIG BUCK BUNNY dvds, I really enjoyed that, indeed, there's a huge amount of information as a video with 4 rectangles (sketch, block rendering, blender viewport and final render), the blender files, the script, an excel with the script timetable and else. That's like having the Trinity helicopter mind tutorial, I lust for more info. I'm having faith to make a short render on the next year.

Big Buck Bunny

2008-05-23T11:44:00.006Z

Well and what's that? Well I am not used to post information of another matters, but this is special is an OPEN MOVIE, yes open source movie, well you have to pay for the DVDs with 720p and 1080p versions:

"You can help us to realize future projects by purchasing the DVD edition of the Peach project.
On the Big Buck Bunny DVD (two disks) you will find:- The movie in best DVD quality widescreen format (versions in both NTSC and PAL)- The HD version of the movie (.avi and/or .mov)- Commentary tracks by the creators- All .blend files, models, textures, and so on... the material used to create the movie.- The original script, breakdown, storyboards- Documentation and video tutorials by the team members about all technical aspects the movie; like how to re-use assets, animate characters, or add new shots."

but I found it really interesting, because it has a great quality at the trailer and in the movie frames. It has been made with blender which is improving a lot since last time I saw and practise, and taking a look at the blog you can see yesterday arrived the dvds for circulation. I have just bought a copy of the set here, maybe a bit expensive for the spanyards but well the money is not for a enormous company is for people with initiative, so here I put some of the images, I hope you help too. For further info, here

Delay due to spyware

2008-05-20T08:10:00.005Z

On Sunday I had one of the most complex spy or virus I ever had. I had the virtumonde.dll spy and Spybot, Adaware, Spyware terminator, didn't work, so I downloaded combofix.exe it turned my desktop to black and the icons have only the description, I don't see the image of them, ie doesn't work, I spent the afternoon trying to restore my machine but at the end I have decided to format, so I will try to make the videos on my laptop.

Few videos "in progress" of BG library on weekend

2008-05-17T07:08:00.000Z

Last night I was playing with the method to scroll strips of scanlines, at the end on the last version of dsmume it runs at 64 fps indeed, so I have decided to use as good enough method. It is a bit annoying that a interrupt can't assign a class' method, but I find a way to solve it elegantly.

I have define a bg class with the possibility of ten strips with y0,yf and own speed. This afternoon I will write code to be able to scroll not only horizontal but vertical, and for the bmp bg and tile bg you want to scroll, shake or wave. Then I'll put the example videos on the blog. A new "unof" new SMB is coming.

I have some few experiments with gravity and tile collision, the next steps after having an alpha release version are:

1.- Setting different "tile class" classes like: transparent, block, teletransport, jumper, ramp, ladder, and so on.
2.- Setting gravity and acceleration for the sprites.(I have tried 2 Newton laws with the jump and I'm delighted how it works :)).
3.- Placing animated tiles..

Libro sobre programacion para la NDS

2008-05-16T07:36:00.003Z

Ha sido una ardua tarea la de programar para la NDS, la verdad que la informacion existente esta, no solo mezclada con el antiguo codigo para GBA, sino que muchas veces se explica pero no hay ni un solo snippet, he estado realizando un libro que explica de cero utilizando la libnds, como poner 4 fondos (2 tiles, 2 bgs) como hacer efectos de scroll, shaking (agitar) y wave (ondear) la pantalla, como poner mapas grandes de tiles, como utilizar sprites y aplicar la gravedad. Faltan muchas cosas aun, pero estoy pensando en publicarlo como primera parte y despues uno mas avanzado con temas mas complejos.

NOTA: Por ahora es todo sobre el 2D, ya que quiero dominar tanto horizontal, como vertical y el isometrico. Mi primer gran proyecto sera horizontal, el segundo vertical (the gusto Tyrian?) y el mas fuerte y tercero sera isometrico (te gusto Diablo? :))

First way to scroll scanlines

2008-05-13T06:50:00.005Z

Yesterday, I was exhausted, but I found out a code that could be interesing, the matters was that it used PAlib, but I think it wasn't restrictive, so I tried. I explain it a bit.

"Way to scroll scanlines (strips) of a bitmap bg via registers"
link here

1.- REG_VCOUNT is a readable register, and tell us in which line, the NDS is painting
2.- If we activate the IRQ_HBLANK interruption and mix with REG_VCOUNT, when we modify the BG2_CX, only will scroll the actual REG_VCOUNT line, so we can make effects like shaking, wavy, scrolling, etc...
3.- It's necessary activate IRQ_VBLANK to make only 192 changes per frame (swiWaitForVBlank();)

NOTES: BG2_CX =_val<<8; means 1pixel scroll, <<4 1/2 pixel scroll, and so on.

Now I'm looking for the way to do with HDMA, ~~because this way needs to use the CPU for itself 192 times per frame, so takes a lot of CPU~~. (I think that because dsmume puts 120 but other emulators tells more than 35 fps, so I'm not sure about consumption).

NDS: Scrolling bitmap bg by software

2008-05-02T07:48:00.003Z

I'm interesting on making a better scrolling of parts of a bitmap background, so I'm thinking of creating regions instead of width*y parts to be able to scroll them faster, if you have done some code to do this, choose to know if I'm in the good way

Libero el visor de factura plus

2008-05-02T07:32:00.005Z

Debido a mi actual trabajo, ya no voy a seguir desarrollando con el facturaplus, por lo que si veo que hay gente interesada, esta hecho en visual c# y la verdad funciona estupendamente aqui, y como es un programa bastante estandar (la base de datos es rígida), a mucha gente le puede ser interesante. De hecho la última version que hice permite recoger datos de diferentes años (carpetas) a la vez para ver asi los pendientes en diferentes años y se obtienen mucha mas informacion de manera rápida albaranes y sus facturas, viceversa, el estado de los mismos, cuantos dias se pasa de la fecha de pago.... Si estas interesado, elige una opcion:

NDS Programming - Get Ready

2008-04-26T20:55:00.002Z

Good Night everyone, well I understand for a .net developer could think why can be interesting programming the nds, really? It's a great machine, you can develop using c++ like in the old days. Are you one of the guys (or woman) who played with the Spectrum, and are you one of who knows that games from de old ages were made by small teams, or one person with great ideas done them. Well I'm, one of them, I'm making with all the (lack) info a book with improvements, and making a libary for a easy use and a map editor in visual too. I'm making a library to make really similar games like New SMB and Zlda games, I don't know exactly the word but it's incredible that a machine like the NDS can understand me talking in C++, so why dont do it. At the moment the library can create easly horizontal levels with two animated layer maps (one tileset per layer) and with plus other bmp backgrounds, with differents scrollings. When I finished, take a look at the moment:

NDS programming - VRAM and allocating

2008-02-29T12:32:00.004Z

Hi everyone, a few days ago I realize up about the NDS programming, I'm trying to put the things in order to understand as I want the architecture of the NDS, so my firsts questions are:

1.- Is the code in the diagram correct?

I mean:

VRAM_A -> BG3 (main) so 0x06000000 goes to BG3
VRAM_B -> BG2 (main)
VRAM_C -> BG3 (sub)

.net Additive versions

2007-11-05T08:13:00.001Z

This morning I've seen a poster and a diagram that shows the .net additive structure

Now I undertand better what is 3.0 and 3.5, here is a link to a great poster of the namespaces. Always is interesting having diagrams like that, overall when people ask us and we are a bit lost.

AI has simmetry?

2007-10-25T14:34:00.000Z

Hi everyone, Today I was playing with an article of Sacha Barber about "Sheeps and Wolves" or "Missioners and Cannibals" here and well might be coincidence might not, but graphically the algoritm makes me the next matrix:

Does anyone know why is simmetrical? I take the steps from the Barber's article and well it's a curious picture.

Spry - Customize the MenuBar

2007-10-18T10:57:00.000Z

After being dissappear for few months (making my commercial web, commercial apps...) being designing I have seen that in the Dreamweaver CS3 there's a interesting AJAX framework called SPRY, so here I saw an example and how to customize with images it:

Result:

How to:
1.- First of all add a MenuBar from the Insert toolbox-Spry

2.- After you add the MenuBar in the webpage, I remove the text and assign for each link a custom id:

3.- And now in a css file (linked to this), I customize simply to this:

Might be for dummies, but sometimes trying things we do it by the complex way.

WPF Moving Controls in XYZ

2007-07-23T14:39:00.000Z

The moment to create something like a game as NeoPets in WPF is coming, today I have made improvements using controls, here I show you how to add movement to the controls on runtime, I have add moving using the mouse and using the keyboard, download the source here
To do that, in the xaml file add to the button:

button keydown="OnKey" previewmousemove="OnMove"

And in the .cs add the next methods:

public void OnMove(object o, MouseEventArgs e)
{
if (e.LeftButton == MouseButtonState.Pressed)
{
b = (Button)o;
SetZ();
Canvas.SetZIndex(b, 99);
b.Margin = new Thickness(e.MouseDevice.GetPosition(null).X - b.Width / 2, e.MouseDevice.GetPosition(null).Y - b.Height/2, b.Margin.Right, b.Margin.Bottom);
}
}

and for using the keyboard:

public void OnKey(object o, KeyEventArgs e)
{
int delta = 20;
b = (Button)o;
SetZ();
Canvas.SetZIndex(b, 99);
switch (e.Key)
{
case Key.W:
b.Margin = new Thickness(b.Margin.Left, b.Margin.Top - delta, b.Margin.Right, b.Margin.Bottom);
break;
case Key.S:
b.Margin = new Thickness(b.Margin.Left, b.Margin.Top + delta, b.Margin.Right, b.Margin.Bottom);
break;
case Key.A:
b.Margin = new Thickness(b.Margin.Left - delta, b.Margin.Top, b.Margin.Right, b.Margin.Bottom);
break;
case Key.D:
b.Margin = new Thickness(b.Margin.Left + delta, b.Margin.Top, b.Margin.Right, b.Margin.Bottom);
break;
default:
break;
}
}

Apparently is easy, the matter about all of this, is that there's only few docs, so I hope you find this useful and encourage you to improve your apps (uis).

Focusing (graphically talking) controls

2007-07-17T14:01:00.000Z

Few days ago my nephew show me a web called neopets, and there I watched plenty of mini flash games, I was thinking on the possibilities on WPF and I decided to start playing with the effects on runtime, here I show you how to change on runtime the focus of a control:

Download sample here

using System.Windows.Media.Effects;
using System.Windows.Threading;
using System.Windows.Input;

...

BlurBitmapEffect blur;
Button b;

System.Timers.Timer t_1;
public void AutoFocus(object o, EventArgs e)
{
b = (Button)o;
blur = new BlurBitmapEffect();
b.BitmapEffect = blur;
blur.Radius=5;
t_1 = new System.Timers.Timer(1);
t_1.Elapsed +=new System.Timers.ElapsedEventHandler(OnTime);
t_1.Start();
}

...

void OnTime(object sender, System.Timers.ElapsedEventArgs e)
{
this.Dispatcher.Invoke(DispatcherPriority.Background, new DispatcherOperationCallback(delegate
{
if (blur.Radius > 0)
blur.Radius--;
else
t_1.Stop();
return null;
}), null);
}

...

public void AutoDifuse(object o, EventArgs e)
{
BlurBitmapEffect blur = new BlurBitmapEffect();
blur.Radius = 5;
((Button)o).BitmapEffect = blur;
}

...

The code is easy to understand, the only matter is the strange way to use a Timer, because if you try to ommit the Dispatcher.Invoke you will have threading problems. The rest I think is easy to understand. Tomorrow I'll show you how to move controls on runtime

Solved the GridView Header

2007-07-13T13:36:00.000Z

Just only an hour ago, I have solved the hard matter to customize the header, due to the matters with the xaml code inside an article here is the link to my comment with the code

The codeproject comment with the code is here

I hope you find it useful or a year of this decade (when you decide to use WPF)

Tutorial: Custom XAML Button - First Step

2007-05-30T18:00:00.000Z

Today I have practically finished my first button in Orcas, there are few things to get customed, and I'll try to explain as for a dummy. Let's start from what you need:

1.- Download Microsoft Expression Design : This is needed to learn a bit of XAML figure structure and design easily , (at the moment I'm solving a problem with a domain when I finished it I'll put all my code files, if you want the source, email me: mailto:juanpablogc@gmail.com , subject: Overrider_300507)

Paint something that you would like to have in a button, (I take a similar look and feel as my RibbonRoundButton).

After you have finished it, you will have to export it to a xaml file. The structure of an xaml (the interesting part for us) is for instance:

canvas...>
ellipse...>
/ellipse>
path...>
/path>
path...>
/path>
/canvas>

(I have problems to add (<) in the blog)

You can imagine the Canvas as a Drawing Table where you layout the components and inside you can add everything you want as Ellipses, Paths... (This substitutes to the OnPaint method which disappears in .net 3.5)

2.- After you have get customed a bit with designer, and exported the file, you must take advice that every component in designer has a name like:

x:Name="Layer_1...
x:Name="Ellipse_0"...
x:Name="Path"...

you must remove the part of x:Name... because a control in Orcas can have only one name.
and to work fine in Orcas, and change Canvas to Grid.

Tomorrow I'll show you how to implement it in a Control Button, as a preview take a look to this screenshot:

Hello World Orcas

2007-05-29T17:59:00.000Z

Welcome everyone, today I decided to install Orcas in my job computer (xp) and this afternoon in my own computer(vista). Well with xp any matter I installed Visual c# express Orcas and compiled without problem. But this afternoon with Vista, ouch.

If you have any problem post me a comment, to tell you how to solve it. And now... Hello World Orcas:

1.- Create a new WPF application

1.1- Go to Project : HelloWorld properties and change the next:

2.- Add a button on the window

3.- Let's create the event (I supposed they will put a design mode early), to do that, go to the window.xaml.cs (yeah we will have to get customed):

4.- And now add the following code:

public partial class Window1 : Window
{
public Window1()
{
InitializeComponent();
button1.Click += new RoutedEventHandler(button1_Click);
}
void button1_Click(object sender, RoutedEventArgs e)
{
MessageBox.Show("Hello World");
}
}

Run and you will have your first VISTA WPF .net 3.5 C# first app, Congratulations :)

Preparing RibbonFastMenu

2007-05-28T12:02:00.000Z

Good Afternoon everyone

I'm preparing the RibbonFastMenu, with
RibbonMenuButtons and RibbonContextMenu,
as you can see in the image, I also included the Transparent Region to place the RibbonForm in the correct place. The constructor will have the
RibbonRoundButton location to place it well.

When you click on the Arrow Region of a button with SplitRegion, you open the RibbonContextMenu (second image). I solved some matters with the round corners and the shadow which was difficult because I haven't found any help about this matter in the Internet but at the end I get it.

Now I have to finish the correct width of the painting of the
RibbonContextMenu, and the Gradients of the RibbonFastMenu.
After that I'll mix with the RibbonForm.

Another thing I have add to the
RibbonMenuButton is the Keep Pressed option, that makes the chance to keep it pressed and send to the Parent Control (Container) to the other RibbonMenuButtons to left this Status. (It will be great to simulate tabcontrols with RibbonMenuButtons or any multichoice selection.

Preparing the RibbonForm

2007-05-24T20:14:00.000Z

Good night again, tonight I present a preview of the RibbonForm, as you can see in the image, it's like OF2007, has the:

RibbonCommandButtons (Minimize, Maximize and Close).

Method to change Hue, Sat and Brightness

Secondary title with armony ForeColor

I'm including the RibbonRoundButton (it looks great)

I have to make all the methods to resize and move the RibbonForm.

I'm finishing the RibbonFastMenu with the RibbonContextMenu. I think this weekend or next I'll publish the article.

The down count is coming to integrate and create a great library. Thanks everyone

The RibbonRoundButton

2007-05-19T21:40:00.000Z

Good Night, I have finished now the RibbonRoundButton, this is like the WM player, Of2007 and VSTA round buttons, and includes fading between colors. I designed with .net 2.0, I think it's a eye candy and it works fine.

I'll publish it in codeproject with the RibbonForm and the Updated RibbonMenuButton with the InfoForm and ContextMenuStrip.

It was difficult to add a shadow under the circle region but at the end I think it finished well.

Another matters with that is the stranges halos that has inside and over, in a few days you will have all the code.

About RibbonMenuButton

2007-05-11T13:14:00.000Z

First of all, I have decided to put all my ControlLibrary free for everybody and Thanks for all the opinions.

Due to my ControlLibrary is getting huge, I thought explain it as I finished the parts, and then publish it as article in codeproject. Here is a screenshot of the RibbonMenuButtonControlTest.

The interesting properties I created are:

Arrow: ToRight or ToDown.
ColorBase,ColorOn,ColorPress (not more back images, more customizable).
GroupPos: Left,Center,Right,Top,Bottom.
ImageLocation : L,R,C,T,B.
ImageOffset (Autoscales).
Radius (of corners button).
ShowBase: to show base or not.
SplitButton: to convert in multiple click event.
Split Distance : to set the size of the contextmenu button part.
FadingSpeed: how fast is the transtition from base to oncolor and back.

I have to add the final touches and if you want to add another functionality, tell me, I'll be grateful to know your opinion and I'll try to add it.

If you want to learn with this controls, I recommend you to take a look to:

this.Region: thats a good way to avoid matters of transparency.
LinearGradient with multiple colors, that makes easy the gradients.
MeasureString : thats a good method to position the text (Beacuse you have to take away the base.OnPaint -> you have to do ALL, including write the text).
Transform Colors Method including Alpha opacity.
The DrawArc Method: As you can see with the radius you can make smooth corners
OnMouseUp: Here you can see what happens when the is SplitButton is activated.

Tomorrow or next, you will see the fantastic RibbonRoundButton. (Another thing, I'm Spanish and I want to improve my English. Could you tell me my faults in the articles? Thank's)
