I there, I have the following problem:
I’ve developed a dialog aplication that uses CExtDateTimeWnd and CExtDurationWnd controls in the main dialog.
The aplication works just fine in debug and release modes.
Now the problem. yesterday, I was changing my pc for another one, and when i try to execute the code in the new pc (in debug mode!) I receive the next error message:

Debug assertion Failed!
File: winctrl5.cpp line: 189

(obviously I perform a clean/rebuild all)

I’ve tracked down the problem and it happens in the main dialog’s construction, in the moment when the control member variable CExtDurationWnd m_wnd_xx; is created, in the line:
(ExtDurationWnd.cpp) m_dtDate = COleDateTime::GetCurrentTime();

My OS data
windows Xp SP2
visual c++ 6.0 sp6

thanks in advanced.

Hi there, the call stack is the next one:

Here is the constructor of the CExtDateTimeWnd class:

CExtDateTimeWnd::CExtDateTimeWnd()
 : CExtDurationWnd()
 , m_bBlankYear( false )
 , m_bBlankMonth( false )
 , m_bBlankDay( false )
 , m_bBlankHour( false )
 , m_bBlankMinute( false )
 , m_bBlankSecond( false )
 , m_bBlankDesignator( false )
 , m_bAutoSelectNext( false )
{
 m_eMode = CExtDateTimeWnd::all;
 m_eTimeFormat = CExtDateTimeWnd::automatic;
 
 m_dtDate = COleDateTime::GetCurrentTime();
 
 SetStatus( CExtDurationWnd::null );
}

As you can see it does not use CDateTimeCtrl at all, so the problem has nothing to do with CExtDateTimeWnd. We can guess that you may incorrectly create the CExtDateTimeWnd control. In the dialog resource editor you put the Date Time Picker standard control on the form. But actually the CExtDateTimeWnd control is not based on the CDateTimeCtrl control, it is a control coded from the scratch, so the Custom Control type should be used instead. Please take a look at the IDD_PAGE_DATE_TIME_DURATION form in the ProfUIS_Controls sample. There you can see the IDC_DATETIME custom control which is used for creating the CExtDateTimeWnd control.

Line 189 in WINCTRL5.CPP corresponds to the CDateTimeCtrl::GetTime() method. But actually neither CExtDateTimeWnd nor CExtDurationWnd use CDateTimeCtrl. Would you send us a call stack so we can see the calling sequence?
