UserControls?

I am a web developer by trade, but have done a little with winforms.
How can I add a winforms user control to an application without having
to create a separate project for each control? From what I have been
reading, you need to create a project for the user control, build it,
and then add it to the tool box. Once it is in the tool box you can
drag it onto the form or other control. I want the user controls to be
part of the base project and add them to the forms without having to
build them each time I make a change. Can I modify the designer.vb
file to do what I need?

You can build the UserControl in the same project. Once you build the
project with the UserControl in it, the control should appear in the
ToolBox, or it may be necessary to close and reopen the project.

If you create a user control in any project it is automatically added to
the toolbox for you once the program is compiled successfully for the
first time.

This has it's advantages and disadvantages. On the plus side, it's quick
and easy. On the minus side, a user-control with a bug in it can mess up
your life because it can throw an exception and your form will be
unusable until you remove the control. This in particular makes
debugging a user control a pain.

The "correct" method is to do as you have read and create it in a second
separate project that you will reference from your application. You can
also debug the user control if you need to using two instances of Visual
Studio.

See Windows Forms Tips and Tricks for some good information on that subject.
