inheriting forms

[bill]

When I try to add an inherited form using the inheritance picker, I get an
error:
"Reference error:"
"Unable to add reference '(source application of inherited form)' to the
current application. Check that a different version of (source application
of inherited form)is not already referenced. "

The form is in a VB.NET executable. I right-click the new project, click
Add-Add Inherited Form. The Add New Item dialog appears, I name the new
form, click Open, and the Inheritance Picker dialog appears. I browse to
the .exe containing the form I want to inherit, and the form is displayed in
the Inheritance Picker list. I double-click the form I want to inherit
from, and I get the error.

Thanks!
Bill

It's because the base form has to be in a dll, Bill!
