Is the stream from a real icon stream? Or from an image stream?

ResourceManager res = new ResourceManager("MyNamespace.Properties.Resources", this.GetType().Assembly);
Icon myIcon = (System.Drawing.Icon)res.GetObject("MyIcon");

hi thanks for reply but when i write this code and compile my app the following error shown me : System.Resources.ResourceManager res = new System.Resources.ResourceManager("AmlakButtons.Properties.Resources", this.GetType().Assembly); System.Drawing.Icon _icon = (System.Drawing.Icon)res.GetObject("PRINTERS11"); Error : Unable to cast object of type 'System.Drawing.Bitmap' to type 'System.Drawing.Icon'

Well this is my first reply in cp, so please correct me if i'm wrong:) This works in vs2k3 so i guess it'll work in 2k5 as well.U can create a Bitmap from the stream, which can then be converted into an icon object. Bitmap b = new Bitmap(System.IO.Stream); Icon tempIcon = Icon.FromHandle(bmpTemp.GetHicon());//Hicon returns a handle to an icon which we use to create a temp icon. obIcon = (Icon)tempIcon.Clone(); Win32API.DestroyIcon(tempIcon.Handle);//we have to create a temp icon and destroy it coz of some resource disposal probs.

I assumed that your resource was an Icon. Try this:

ResourceManager res = new ResourceManager("AmlakButtons.Properties.Resources", this.GetType().Assembly);

Bitmap myBitmap = (System.Drawing.Bitmap)res.GetObject("PRINTERS11");
Icon _icon = Icon.FromHandle(myBitmap.GetHicon());
myBitmap.Dispose();

I need Icon.FromHandle() method in Compact Framework but the FromHandle() method is not supported by the CF 1.0! So I searched a while and found an article at OpenNETCF.org[^] which did it: The code worked fine with PPC2002 and WM2003 but not works under WM2005... There seems to be a problem with the palette colors... The icon can be displayed but with wrong colors or transparency is a problem. 1. The SDF uses CreateDIBSection() with a BITMAPINFOHEADER parameter but MSDN and function prototype says that it is a BITMAPINFO. 2. P/invoked BITMAPINFOHEADER is missing biClrUsed and biClrImportant 3. Correcting issues 1+2 does not solve the problem. Very strange: If the application was launched using the debugger it works (icon displayed correctly). If launched without debugging (from within VS) the colors are not correct (black instead of transparency) The debugger seems to initialize something wich causes this behaviour but of course the app should be able to display the icons correctly without a debugger ;-) Thx for some help!
