Substitute CMonthCalCtrl in CDateTimeCtrl

See more:

MFC

Hi,

I'd like to use a personalized CMonthCalCtrl in my CCustomDateTimeCtrl.
I've tried to catch the DTN_DROPDOWN message; in my CCustomDateTimeCtrl::OnDropDown method, I display my own calendar but when I've selected a day, the old calendar appears.

If at the end of OnDropDown I put;

GetMonthCalCtrl()->PostMessage(WM_CLOSE);

then the old calendar never appears, but "one click" of the mouse is not sent to the dialog.

Any suggestion?
