Hi NG,

when trying to drag a UserControl from the toolbox on a Form, this exception
rises:

The exception was ""null" is not a valid value for the 'stream'.".

?

Thank you

Rudi

And what was the stack trace? That sounds like an
ArgumentNullException, but without knowing what threw it, there's not a
lot to go on.

you try to use a stream that is not properly initialized. for example, you
might have tried to create a bitmap or an icon from non-existing assembly
resource (I often get this error in such scenario).
