The questions that work best in this medium are specific rather than the
overly broad question you posted.

Why not repost the question by saying what you are using - .Net/MFC/SDK,
what you have tried and how it failed?

OK, so post a small snippet containing what you tried and how it failed you.

IMO, newsgroups are not well suited to tutorials or how-tos. If that'w what
you are after you might want to google for something or take a look at this:

its a .net forms app in C++ ,
the problem is that i cant paint to a window unless its inside an
event like e->paint blah blah

You are supposed to do your painting inside the Paint event, or the OnPaint
& OnPaintBackground overrides.

Have a look at http://www.bobpowell.net/faqmain.htm for info on GDI.NET.

Reminds me of a line from the movie Cool Hand Luke - "What we have here is a
failure to communicate."

Is it that you don't know how or that something you have tried fails?

Do you know that outside the paint event handler you can call
CreateGraphics() to get an used to paint a control like the one you get
inside a paint event handler?

In any case, WinForms is neither my specialty nor the subject of this group.
You may want to post again in one of the

microsoft.public.dotnet.framework.windowsforms

groups.

Correct - you're not supposed to. You CAN use CreateGraphics, as William's
said, but it's best to call Invalidate and do any drawing in OnPaint.
Otherwise you'll almost certainly get overdrawn when a Paint event is sent
to the control / form.
