Drag and Drop Help

Question

http://www.vbaccelerator.com/home/NET/Code/Controls/ImageList/Sophisticated_Drag_Drop_Images/article.asp I have been refered to the site above to implement the drag and drop of images. In he site it says to drag and drop images it implements ComCtl32.DLL ImageList. When I go to add it as a refrence on my project, so I can make use of the library. It gives me an error "A reference to 'C:\WINDOWS\system32\comctl32.dll' could not be added. This is not a valid assembly or COM component. Only assemblies wiht extension 'dll' and COM components can be referenced. Please make sure that the file is accessible, and that it is a valid assembly or COM component." I don't why this error is occuring, but I can't implement drag and drop of images becasue of it. I know it is possible to implement it, so if anyone knows how to do it. Please drop me a line!
