I have created a simple project with two forms: 'form1' and 'baseform'

When I tried to inherit 'form1' from 'baseform' (Inherits baseform), the IDE displayed the following error message  :
----------------------------------------------------------------------------------------------------------------------------------------------
An error occured while loading the document. Fix the error, and then try loading the document again. The error message follows:

The disigner could bot be show for this file because none of the classes within it can be dsigned. The designer inspected the following classes in the file:

Form1 --- The base class 'Project.baseform' could not be loaded. Ensure the assembly has been referenced or build if it is part of the project.
------------------------------------------------------------------------------------------------------------------------------------------------

However the project still can run properly!

Thanks in advance.

This is because you have some code in one the events raised when a form is loaded (Load, Activate, Paint, ...) in the PARENT class that cannot be evaluated for the designer.

Remove this code from these events and your child will appear correctly.

No, both form1 and baseform are simple blank form.

Anyway, I have solved the problem already. The solution is to rebuild the project before the form designer can display the inherited form!
