From: Mr. X. on 19 Mar 2010 06:54 Hello. I want to create a new class (VB 2008). What I did : add new class. and wrote : Public Class MenuButton Inherits Panel .... The code isn't compiled : Error 1 Base class 'System.Windows.Forms.Panel' specified for class 'MenuButton' cannot be different from the base class 'System.Windows.Forms.UserControl' of one of its other partial types. I need little sample code, so I can go on ..., please. Thanks :)

Your user control has a second .designer file that is associated with your code file. You changed the inheritance in one file, but not the other, thus the confusion. It is actually a lot easier in the long run to not do what you did. You should just add a class as normal, so you don't get the designer file. Then you don't run into this issue when you add the inherit statement. Mike

Do you want to derive your class from Usercontrol or from Panel? If you've created a Usercontrol as you've desribed, you can not inherit from Panel. If you want to inherit from Panel, you must not create a Usercontrol as described. Instead just add a new class (add new item -> class). -- Armin
