I am now stuck trying to go from a handle to an icon, to loading the icon into the image list control, which requires me to use a picture object. In other words, I need to translate an icon handle to a picture object???

Hi George,

Thanks for the response, although I don't like the way this sounds. I thought of one other possibility. Do you, or anyone reading this, know of any ActiveX control that will allow me to supply an exe, dll, or ico file along with the resource id, and have it return a picture object that I can use in the image list?
