Changing the Icon

[ddspliting]

In Visual C++ programing, we can change the icon of the EXE file.Is it possible to change the icon of a window form program's EXE in C#? if it is then i will be grateful if anyone tell me about it... waiting....

Try googling around :)

Some comments on applications and icons: 1. An application typically has two different icons: - the application itself has an icon at the file level; it gets used by Windows Explorer; you set it as a project property. - any form can have an icon; it is a Form property, that you can set through Visual Designer. It also shows up in the task bar's button (if the Form shows in task bar). 2. an icon file can hold multiple icons (icons at different sizes), and Windows will pick one depending on circumstances, so if they do not all look alike, you may get very confused. 3. I tend to create icons programmatically; the following code converts a (best small, square) image into a simple icon:

string filename=popupNode.getLongName();
try {
Bitmap bm=(Bitmap)Image.FromFile(filename);
if(bm.Width!=32 || bm.Height!=32) {
bm=new Bitmap(bm, 32, 32);
}
Icon icon=Icon.FromHandle(bm.GetHicon());
bm.Dispose();
string filename2=Path.ChangeExtension(filename, ".ico");
Stream stream=new FileStream(filename2, FileMode.Create);
icon.Save(stream);
env.output("Created icon "+filename2);
} catch(Exception exc) {
env.output("Failed to create icon from "+filename);
env.log(exc);
}

Hope this helps.

Thnxx for sharing this precious info! But the fact is i ve changed the form icon as u mentioned i guess.Now i want to change that exe file icon. say in the debug there is a exe file named "dark.exe".This file has its typical exe icon.you know which is common for windows! tht window like. Now as in visual C++ we can change exe file icon to any icon file we want or can convert a bitmap to icon file like you ve posted the code for it.There is already option for tht in the IDE. If there is an option present in C# IDE(i m using Visual Studio 2005 by the way) then i ll be glad if you tell me if u know already! or other method ....

Hi, the app's exe icon is a project property, hence right click the project in the solution pane, choose application tab, and specify the icon file/resource there. :)

Just look in the properties pages for the project. If you want to embed multiple icons into the executable which are viewable by Windows then might I suggest taking a look at my article[^]. Shameless self-publicising but hey...
