I want to be able to access the control members of a form from within a
class. So i designed my constructor something like this

Form1 parentForm;

ClassName ( Form1 frm )
{

parentForm = frm;

}

But when I try and pass the form to the class it errors.

ClassName myClass( this );

What am I doing wrong ???

Cheers

I think that what you want to do is this:

ClassName myClass = new ClassName(this);

It will only work if it is done inside Form1, since otherwise "this"
would not be of the adequate type to pass to the constructor that you
defined.

Well, that's not the syntax used for a constructor call. You need:

ClassName myClass = new ClassName(this);

Hi,

You need to get a book of C# , some basic stuff like syntax, etc.
