Copying A Control Not As A Reference

I have a Control that I want to copy as a copy of the Control, not a copy of
the reference to the original. My reason for doing this is because some of
the methods I would calling would prevent proper rendering afterwards. I
access the Control as a parameter of a function, as follows:

Private Function MyFunction(ByVal ctrl As Control) As String
'code that will make a copy of ctrl
'my function code
End Function

(NOTE: I am using VB.NET and .NET Framework 1.1) Thanks.

You have to pass the ctrl ByRef in order to be working with the one you
want to copy.

That does not help. Let me try explaining my problem differently with an
example:

Private Function MyFunction(ByVal ctrl As Control) As String
    dim copyofctrl as Control

    'copyofctrl=ctrl    this will be replaced with code that will assign a
copy of ctrl to copyofctrl that points to a new instance of whatever type
ctrl was
    'my function code
End Function

In the part of my code labeled "my function code" I want to be able to do
ANYTHING I WANT to the local variable copyofctrl without having any effect
on ctrl. Hopefully this clears up what I am trying to do.

No, you should pass it 'ByVal' because 'Control' is already a reference
type.

Nathan,

If a class is serializable you can almost forever copy something to
serialize the object first and than deserialize it again.

I hope this helps,

Cor
