Kevin,

>>Sort of. What I can't quite get my head around is the creation of my custom base classes (which are supposed to be generic) within a specific solution, and them then being available to other soltions?<

Well, when you need to add the custom base classes to another solution, you simply add a reference to it, just like you would with any other class library. And add it to your toolbox as well, so you can drag the controls to your IDE. The namespace for your custom base classes should be something like MyCompany.WinUI.MyBaseClasses.

>>>>However, this leads to another question. How do I create this class, without it being tied to a specific Project / Solution? In VS2003, File / New / File does not give an option to creaate a standalone class.<

>>Well, to start, you'd need to have the class library included in your Solution so you can compile it to a .DLL. We have one class library where we keep all our custom base classes (there's other classes in addition to the non-visually sub-classed controls ... such as certain types of forms that we use a lot). Anyway, this class library is always added to the solution of whatever app we're working on. We control the versions by using VSS and sharing those files.
