I don't understand what exactly you want
but EnumChildWindows(..) might help..
See documentation for details [^]

something like this

HWND hwnd = ::GetTopWindow(this->GetSafeHwnd());
// while we have a valid hwnd, 

// loop through all child windows

while (hwnd) // change with for
{
    // do something with the hwnd

    // and get the next child control's hwnd

    hwnd = ::GetNextWindow(hwnd, GW_HWNDNEXT);
}

Somethings seem HARD to do, until we know how to do them.

Controls within a CWnd

Hi,

I guess this is a newbie question: I havent had much experience of user interface development in MFC, only dialog based apps so far.

I'm developing a MFC Ribbon MDI application in VS2008 and would like a CDockablePane with a few controls on it, such as 2 date time pickers, a few labels and buttons. Note CDockablePane eventually inherits from CWnd.

What's the best way of doing this? Anyone got any advice?

thanks,
Mark.

The first point to get an answeer is to post a answerable question.
We all suspect that you have a file tha on its 72th line calls the haed of the stack you post, passing a wrong paramenter or a paramenter carrying wrong values.

But the only way for us to know abuit it is to see that line and at least the 10 liens before it.
