Hi Kevin,
Go into Visual Studio, right click on the project and select properties. Look in Common Properties, General and you will see "Output Type" - just change it to "Class Library" and then re-compile. This will give you a DLL.
HTH.

>>>>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.
