When ExtractAssociatedIcon is used with bitmaps, a thumbnail image may be returned instead of an icon if the system that is running the application has a registry setting that causes bitmap files to be shown as thumbnail images.

The following code example demonstrates how to use the ExtractAssociatedIcon method. To run this example, paste the code into a Windows Form and call ExtractAssociatedIconEx from the form's constructor or Load event handler.

private void ExtractAssociatedIconEx()
{
    Icon ico =
        Icon.ExtractAssociatedIcon(@"C:\WINDOWS\system32\notepad.exe");
    this.Icon = ico;

}
