Inherit from a Windows Form

[Wu Qinliang]

I created a Windows form named myform1, and put some controls on it. I need
another form named myform2. Because myform2 is similar to myform1, so I want
myform2 to inherit from myform1, i.e:

Public Class myform2
inherits myform1
.......

End Class

However the code above can't work. myform2 even can't be displayed in IDE.
I am appreciated for any help.

Choose "Project" -> "Add inherited form..." from VS.NET's menu. Then select
the form to inherit from and add your code to the inherited form.

And what error do you get when you try to open it in the Designer?

Have you marked either the class myform1 or any of its methods as
"MustInherit"? The Designer can't cope with "abstract" forms.
