This is more a mental note for me...I finally decided to take the time to add a new template (based on an Inherited User Control) to the Visual Studio “Add New Item” dialog. Here's what I wanted, and eventually got (note: I work in VB.NET, so what you see may vary):
First off I got the new item, icon, and positioning in the list (2nd, next to Windows Form) working by fiddling around in the “C:\Program Files\Microsoft Visual Studio .NET 2003\Vb7\VBProjectItems“ and “C:\Program Files\Microsoft Visual Studio .NET 2003\Vb7\VBWizards“ folders, copying and amending the existing “WinForm” items. This is pretty straightforward...
