Thanks for the reply .... it worked out.. Now the major task for me after showing bitmaps of controls on toolbox is enabling drag 'n' drop facility of controls onto the container. I think IDesignerToolBoxSite interface is used for this. But how to use this interface in my application is what is troubling me? :(( Can u help me in this regard?

Thanks, My problem is solved. One more thing, i need to show selected activex images in a ToolBox on start of application and allow user to drag n drop controls onto the container...Just like we do while designing a dialog box(adding buttons,etc). Any help on how to do it?
