OCX in a OLE container

Is there any sample which illustrates how to create a OCX
control in a OLE container ? I have looked around and all
the samples seem to detail using OCXes in regular applications.
Another problem I am encountering is that the OCX does not
get painted on my main window when I create one. I traced
thru the debugger and found that MyOCX::OnPaint does get called
but nothing seems to be visible. Spy++ also reports that the control is
there. I know I am not setting something very basic like mapping mode.

Hi :
The painting problem is due to the fact that your OCX control does not have
a window in design mode. So naturally your OnPaint will not get called.
Containers handle Painting in design time slightly differently. The
container itself issues WM_PAINT rather than asking the control to send one.
If you have OnDraw function you will see it being called even in design
mode. Beware of cordinates, though. The top-left is not 0,0. So handle
your painting properly to nullify effect of non-zero corner.

I had the same problem when first trying to use an OCX control in
an SDI app. Does this control's class have an Draw() method or the like? If
so, then you'll probably need to call this method in the
OnDraw() message handler of your view (or main frame if not using views).
Otherwise, you can try calling that OnPaint directly...
though this doesn't seem too clean.

The article I wrote for MSJ, which appeared in the April, 1995 issue, does
exactly this.

So, how I can get a top-left corner in OnDraw or even in OnSize
function?

Lech -
In OnDraw, you're given a rectangle as a parameter. That's the rectangle you
should use.
