Pete,
Right-click on the ToolBox, choose "Add/Remove Items". When the Customize ToolBox dialog comes up, click on the "Browse" button. Then browse to the .DLL that contains your base classes.

>Hello All, this is probably a newbie question but I can't find anything on it , I'm in the process of creating my own base classes of the basic controls in DOTNET ( textboxes,lables etc...) , is there a way to place them on the IDE toolbox under another tab ( like VFP ) ? , it's a bummer having to change the base classes with find and replace
