[MFC-ActiveX] Inserting an ActiveX into an ActiveX

I tried to include a WMP control into my activex, but it didn't work..

could anyone post me a sample code that does this?
thanx

In my control class, i have a CWnd member , acting as the wrapper window for WMP.

When i try to create the control, i call the CWnd::CreateControl method of that class member, and its return value is non zero, indicating success.

but after that, the wmp control (whose ProgID is "WMPlayer.OCX.7") will not be visualized.

i tried with another control ("mscal.calendar"), and the result is the same.

then i created a web page which displays both the controls above (using <object> tags), for verifying that they work, and they do.. when i open the page with internet explorer they are correctly visualized.

i also have tried to visualize them in an MFC application that creates a DialogBox.. and inside the dialog box those controls are correctly inserted and visualized.. but in my activex they don't.

perhaps the parent window specified in the CWnd::CreateControl method MUST be a CDialog??? in my activex, the parent window is a COleControl, is that the problem?
