Print OCX Control

Howdy,
I'm working on an MDI app, in which I use a Graph .OCX control (Lite Graph Control from BitsPerSecond). I want to be able to print a document with a graph and other stuff in it. If I use the .OCX control's printing functionality I only get the graph on the paper, when I try to print.
I want to know how to get the device context of the control,that is, how to solve the problem that occurs when I try a call like:
pDC -> MyOcx.MyFunction(); in the OnDraw function, which seems to be a common way to solve problems like this otherwise.
The result of this is "error:MyOcx is not a member of CDC".
If anyone knows how to deal with my problem, please give it a try.

thanks alot,
Jan Allen

You are right that OnDraw in your container application is right place to do it. But you have to get window handle of the control window (check OCX standard interfaces, I just do not remember which one returns it) first and then call API function GetWindowDC().

I'm missing something major here.
Can you please give an example (with the grid control or something).

OnDraw(..)
{
    HWND hWnd;
   // use  IOleWindow::GetWindow( HWND )
    pIOleWindow->GetWindow( &hWnd );
   HDC hDC = ::GetWindowDC( hWnd );
