>how can I subclass a form and use it in a project without having to include the parent class in the project. With custom classes, I saw that this is possible. Now when I build the Exe file, it looks for all the parent classes.

As Bill said, you have to include the parent class in the project. To base a form on another form, you can save the original as a class. In the form designer, make sure you have the form selected. Then from the menu do File > Save As Class
