Bonnie,

I created a class and pasted in the code. I tried to compil it and
got an error:

Program '...MCMControls.exe' does not have an entry point defined

What am I doing wrong?

Thanks

>That's it. These controls can't be sub-classed visually, but as you can see, it's easy enough to do it in code. I have all the basic controls sub-classed in one class library file. Once they're added to the ToolBox, then can be dragged onto any design surface in the IDE.

>To add to the ToolBox, do the following: When you have the IDE open in the designer view (not the code view), go to the ToolBox, right-click anywhere and choose the Add/Remove Items, click on Browse and find the .DLL where your sub-classed controls are (you obviously needed to have compiled the class library after you created it). That's it ... they'll then be added to your ToolBox.
