After scripting on both of them, I built the project and I got 1 dll file: WindowsControlLibrary1.dll.

How can I do that, what should I do to get the controls inside the dll file. I want to use it as part of the new project. So that if i call function like: UserControl1.Show(), the UserControl will be appeared under the main form of the new project, and have all function as child form.

Try
    ao = [Assembly].LoadFrom(sFullPathIncludingFileName)
    o = ao.CreateInstance(sAssembly & "." & sClass, True)
Catch ex As Exception
    Throw ex
End Try

Can someone help me? If I could do that, next I want to add the path of the dll inside SQL Server database. When I run the main form, it will read the path, and dinamically run them as the MDI child on runtime.
