Hi,
I'm completely new to C#, so here is my question:
Why my C# program (COM dll which I can call from C++ application)
cannot see namespace
System.Windows.Forms..
When I'm typing in "using System..." after the System. the only "W"
prompt is Web, so I cannot use in my program something like
MessageBox.Show( "blah, blah, blah" );
Thanks,
Alex 7 1665

Have you referenced System.Windows.Forms dll in VS solution explorer (if
your using VS of course).

Glenn, thanks for the quick answer,
Yes, I'm writing my project using VS 2005. So currently I have in my
..cs file
using System;
using System.Runtime.InteropServices;
using System.IO;
using System.Collections.Generic;
using System.Text;
with no problem..., but ...System.Windows is not available on some
reason...

OK, I've figured it myself, I had to go in Project->Add Reference and
add:
System.Windows.Forms.... now everything is fine. I just don't
understand why this namespace was not included in my project
automatically...

Right click on References in solution explorer and click Add new reference.
Then choose System.Windows.Forms.dll from the list and you are done.

It depends on the project template. System.Windows.Forms.dll is referenced
only when you create a Windows Application project

Because it's not essential for everybody, not many people want it
included unless you have an explicit need for that..

Maybe the MessageBox was just an example, but just in case that's what you
intend to use:
Throwing up a MessageBox from inside an inproc COM object will rarely (never
IMHO) be a good idea.
