Designer does not swallow form derived from mustinheritform

[vincentnl]

I am usging VB .net

 

I have a base form that has mustoverride 's and thus mustinherit in the class definition.

 

Public MustInherit Class BasicForm
   Inherits System.Windows.Forms.Form

 

If i inherit from this class

 

Public Class SwitchBoard
   Inherits BasicForm

 

The designer (the thing in the IDE that let's you edit in WYSIWYG mode on forms) gives an error, for it tries to make an instance of basicform. I know it is an abstract class, just inherit from it, and show my switchboardclass !

 

How can this be fixed or worked around?

 

Is it clear what i am asking?

Unfortunately the designers cannot support an abstract form as a base, because they have to actually create an instance of it to show on the design surface.

I agree, but isn;t it stupid !! This must have come up before !! Why design it that way, it is so obvious, and not easily missed, so MS must be aware of it

And how would you suggest they instantiate your abstract class? :)

They trie to instantiate my abstract class when they want to display a derived class. They should only try to instatntiate the derived class, and just incorporate the data from its parent
