Date Time Picker Problem(IDC_DATETIMEPICKER)
-
I use VC++ 6.0 to make a MFC dialog based project, simply add a Date Timer Picker, using classwizard add two member variables for this datetimerpicker control(CTime, CDateTimeCtrl), then compile and run this simple application, ok, then interface comes out, datetimepicker is initialized to be 1970-1-1, when I reset time to be any time before 1970-1-1 I get this error message: Debug Assertion Failed Program: C:\test\debug\test.exe File: timecore.cpp Line: 40 what's wrong here? can anybody help me out? thanks

CTimeobject wraps a standard Ctime_t. This type cannot represent a date before 1 January 1970, and the assertion is telling you this. Stability. What an interesting concept. -- Chris Maunder -

This works fine for me:
COleDateTime from(1968, 9, 6, 16, 10, 0),
to(2006, 4, 29, 16, 23, 15);
m_datetime.SetRange(&from, &to);

hi David, I tried your soluation, but the problem is still there, can you provide another simple sample? thanks

Perhaps I do not understand the problem. The code snippet I provided gives the control a minimum date of 6-Sep-1968, which is earlier than the 1-Jan-1970 date that was originally confining you. If you have a relevant code snippet that we could look at, we might be of more help.
