    It is impossible to add forms to existing projects

    Hi!

    Is it a bug or a feature? I suppose it a bug.

    It is impossible to add forms to existing projects. You can only add forms derived by existing forms to existing projects no other options are given.

    Error Removing Registry Key?

    If it is not causing you any issues i would suggest for you you not alter the Registry.

    Altering the Registry in any form of way may cause your Operating System to stop responding and or functioning.
