Hi,

In the MM .NET Developer's Guide under Application Security, Step 6: Displaying a Users Form it says :

The Framework contains an mmUsersForm class that allows you to maintain application users and the roles to which they belong:
You can subclass this Framework-level form and customize it as needed.

When I follow the guidelines in the Visual Studio help file, "Inheriting Forms Using the Inheritance Picker Dialog Box", I end up with a subclassed form and the error message when trying to view it in the UI designer :

An error occurred while loading the document.  Fix the error, and then try loading the document again.  The error message follows:

Object reference not set to an instance of an object.

The error message is not uncommon and I usually know what it is that I have forgot to do, but in this case all I have done is inherited from a class. Has anyone encountered the same problem?

Regards

-Filip
