CComControl::CreateControlWindow
By default, creates a window for the control by calling CWindowImpl::Create.
virtual HWND CreateControlWindow(
HWND hWndParent,
RECT& rcPos
);
Parameters
hWndParent
[in] Handle to the parent or owner window. A valid window handle must be supplied. The control window is confined to the area of its parent window.rcPos
[in] The initial size and position of the window to be created.
Remarks
Override this method if you want to do something other than create a single window, for example, to create two windows, one of which becomes a toolbar for your control.
Example
RECT rc = {10,10,210,110};
HWND hwndParent, hwndControl;
// get HWND of control's parent window from IOleInPlaceSite interface
m_spInPlaceSite->GetWindow(&hwndParent);
hwndControl = CreateControlWindow(hwndParent, rc);
