Need help on CDateTimeCtrl class

[John502]

Hi, I need some help on DateTime control, by default it will displays the current date on datetime picker. If you have changed that date to next month then i need to display one error message box. just like for example today date is 3/2/2009 and i have selected date in datetime picker as 20/2/2009. This is wrong right..? So i need to throw one error message box, Can any one help which event will get fired when datetime picker will changed. I have already tried with DTN_DATETIMECHANGE, it's not working, that the event is getting executing repeatedly.. Can any one help me regarding this..? Thanks in advance...

Why DTN_DATETIMECHANGE does not work for you? It is WM_NOTIFY message and once it is fired all you need is to cast lpChange = (LPNMDATETIMECHANGE) lParam; and read DWORD dwflags; // this should be GDT_VALID and then SYSTEMTIME st; to see what time was selected. Then if it is month from now display a message.
