You can do it, but you have to get a bit tricky. The window border itself can’t be changed, but you can make a borderless window with a shape inside of it that does what you want. You then have to enable dragging the ‘window’ based on dragging its contents, but it’s not a big deal.
Start by setting the following styles on the window:
WindowStyle="None"
Background="{x:Null}"
AllowsTransparency="True"
ResizeMode="NoResize"
Inside this window you’ll need to place a Border object. Inside the Border you can place whatever you want. Now on the Border set its CornerRadius to something like CornerRadius="0,22,0,22" and set your fill and stroke as desired.
Finally, you’ll need to be able to reposition the window regardless of where the user clicks. Fortunately WPF lets you capture events both on the way down (Preview) and on the way back up through the element stack (Element). So to complete your project, in your window class add the following code:
protected override void OnMouseLeftButtonDown(MouseButtonEventArgs e)
{
base.OnMouseLeftButtonDown(e);
DragMove();
}
And that’s it. You can use this trick for creating windows of literally any shape. Even animation should be supported, though I haven’t tried it. Disclaimer: I’ve only tried this on Vista. I think it SHOULD work on XP, but the Desktop Window Manager in Vista may make a difference.

Ha ha ha. I just realized you only needed the rounded rectangle and I took you all the way to the rounded window. Oh well, all you needed was the CornerRadius bit. And I think you even wrote an article already? Well, good job!

Haha, yes I wrote an article for a Shape-derived class called PartiallyRoundedRectangle before I found out about Border's ability to do essentially the same thing. I found out about that through the article though, so it wasn't a complete waste of time. 
Thanks for the in-depth instructions for making rounded borderless windows even if it's not exactly what I was asking for.

Hi,
I'm actually writing a CLIENT/SERVER TCP/IPv6 application, under Microsoft Visual Studio C++. In which the SERVER is a file server application and the CLIENT is a "Multiple Document Interface (MDI)" and "RichEdit Text" application that can open multiple files from the server.
I would like to add a Toolbar window into my MDI frame window, to do this, I've created the Toolbar window with the "CreateToolBarEx" function.
But the created Toolbar window is located in the client area of the MDI frame window and each time a new MDI child window is created to hold a new document, it erases the Toolbar window in the client area.
My question is how can I do :
1) To change the client area size so that fits
height(MDI Frame window) - height(Toolbar window)
OR
2) To include the Toolbar window into the
non-client area like the Menubar and the Titlebar
So that the MDI child window can't anymore erase the Toolbar window in the client area.
Thanks,
Alain NGUYEN

Sorry if my english is not good.
I'm building a program on Windows that take in a table and draws chart, text and some animation effect(text running in bottom of screen). The program must export that to a .avi file.
How can i do that?Do you know any library that can directly manipulate a .avi file like draw on a frame.
Or a library can convert a list of pictures to .avi file.

Hello to anybody.
I would like to know how to create a graphic interface like the one used, for example, in PowerDvd or in Windows MediaPlayer which represents the music using graphic effects.
Thanks for any valuable aid you can give to me.

Winamp comes with AVS which lets you make visualisation with a simple scripting language

Its quite good as a soft introduction into graphics programming

In Windows, you can hold down the alt key and press the "print screen" key to copy an image of the active window into the cut/past buffer. Then you can bring up paint, use paste, and save or print the image. You can also use ctrl and "print screen" to copy the entire screen.

Hi,
Is there a way to convert a system.drawing.image to system.drawing.bitmap without having to save it to disk first.
Would appreciate any good help
thanks

There's three System.Drawing.Bitmap constructors that take a System.Drawing.Image as a parameter...

Hi,
thanks for the reply. Im new with C# (started with TP and mainly work in php / MySQL) so constructors is all new to me... Been looking around and cant seem to find the right thing/way to do this.
if i have
System.Drawing.Image modimage;<br />
System.Drawing.Bitmap modbitmap;
changes are first done to modimage and then i want to do something like
modbitmap = modimage;
and then carry on with changes to modbitmap.
obviously the modbitmap = modimage; does not work as it is like trying to say
strSomething = intSomethign;
it would be nice if there was a thing like
modbitmap = modimage.tobitmap(); lol
anyway, my trials have proved fruitless so i am hoping that you would be kind enough to spare a min and help me out.
thanks in advance.

Try this:
modbitmap = new System.Drawing.Bitmap(modimage);

Try what GrinderDev suggested

You could also just cast it... (This is a bit faster and uses less memory).
bitmap = (Bitmap)image;

Yes, most of the time that will work; what if the image happens to be a Metafile?

I've never used metafiles.
...but I suppose that would give an error.
Do people still use wmf/emf?
I've always concidered them quite an old (and outdated) format.

I don't know.
My point is: (Bitmap)Image.FromFile("test.WMF") could throw
since there is a difference between Bitmap and Image classes, so I prefer either the
constructor approach (hoping it is not too expensive) or an "is Bitmap" test (C#).

Good example of why casts are dangerous.
C# really allows casts? hehe

Hi all,
I'm trying to get the simplest of D3D9 programs working (coloured window). But keep getting this error when I run the SDK samples, and a website's sample i'm trying to follow.
Error 1 error LNK2019: unresolved external symbol _Direct3DCreate9@4 referenced in function "long __cdecl InitD3D(struct HWND__ *)" (?InitD3D@@YAJPAUHWND__@@@Z) CreateDevice.obj <br />
Followed by...
Error 2 fatal error LNK1120: 1 unresolved externals e:\Program Files\DirectX SDK\Samples\C++\Direct3D\Tutorials\Tut01_CreateDevice\Debug\CreateDevice.exe 1 <br />
By trial and error, I think its this line thats screwing it up...
d3d = Direct3DCreate9(D3D_SDK_VERSION);
Any ideas on how to fix this?
Mark.

Have you linked to d3d9.lib?

Yea I think I did it right...
I had put:
#pragma comment(lib, "d3d9.lib");
in my code.
If you want to review the whole program, you can find it here.
