Retrieving an Image from a resource file

[Doug Handler]

I'm using VS2k5 and i've added a bunch of images to the project's
resource.resx file and thus they reside in the Resources folder. I want to
dynamically add an image to my project. I have no problem adding an image
if its part of an existing UserControl or Form, but just as part of the
general project, I can't seem to figure out how to obtain the info via the
ComponentResourceManager.

Thanks in advance.

Find the correct resource imageName looking at your assembly Manifest (use
ildasm), then try this...

public Bitmap getBitmap( string imageName, t
AnyTypeWithinTheSameAssemblyNamespace ) {

Assembly myAssembly = Assembly.GetAssembly(t);

Stream myStream = myAssembly.GetManifestResourceStream( t, imageName );

Bitmap b = new Bitmap(myStream, true);

myStream.Close();

// Get the current desktop screen graphics.

Graphics g = Graphics.FromHwnd(IntPtr.Zero);

// Make a bitmap using that color depth.

Bitmap bitmap = new Bitmap(b.Width, b.Height, g);

// Clean up.

g.Dispose();


// Start drawing on our new bitmap.

g = Graphics.FromImage(bitmap);

// Copy the loaded bitmap to the bitmap with proper screen depth.

g.DrawImage(b, 0, 0, bitmap.Width, bitmap.Height);

// Clean up.

g.Dispose();

b.Dispose();


return bitmap;

}
