yes,the Reflector could do that,but,i want do that with my C# code .

i know the way you said, and, you see , if i just know the interface'name ,can i have the dllTypeInterface object?

thank you. it works.

yes , just a window form as the Desktop Background behind other icons ,perhaps,a application running at the same time can notes me something to do throw the form.

Check this out explains and demonstrates the func. you are looking for. http://www.codeproject.com/useritems/ExtendedListBoxControl.asp Hope it helps. Mike Started out with nothing and still have most of it left!

simply, add image list with some icons, create items there (by hand in listview tasks, or programatically), columns... and groups... VirtualVoid**.NET**
