Problem with COleDateTime Status

[maverick786us]

I am initializing a COleDateTime object with the current date like this, and its m_status is coming invalid. Can someone tell me the reason? This is the first time I've come across this kind of problem, while initializing COleDateTime with current time

COleDateTime dtInstalled = COleDateTime::GetCurrentTime();

I never saw such a situation.
Try to debug this code and see why the status is set to invalid.

yes while debugging only I saw when I initialize it, with current date, its m_status value comes out to be invalid and somewhere in net i checked out that anyone using Direct X 9 SDK is encountering this problem, which is consiered to be a bug, but i am unable to find no solution so as a temporary alternative I am using this condition

if (dtNow.m_status != COleDateTime::valid )
	return 0;

You are not understanding the suggestion to debug it. You need to step into the MFC source code and determine exactly where the call is failing. MFC uses various time-related functions (time(), GetLocalTime(), GetSystemTime(), GetTimeZoneInformation(), etc.) and somewhere in that source code you should be able to determine the point of failure and why it is happening.

While debugging I noticed, right after initialization..

COleDateTime dtInstalled = COleDateTime::GetCurrentTime();

It shows the value of m_status

dtInstalled = {m_dt=40203.667685185188 m_status=invalid }

So this invalid value later in the code while making this kind of comparision

if(dtNow - dtInstalled > COleDateTimeSpan(120, 0, 0, 0))
	return 0;

Breaks the code thus causing debug assertion failure

Did you step in (F11) the COleDateTime::GetCurrentTime() source code?

Yes while going inside at initialization (F11)

ATLCOMTIME_INLINE COleDateTime WINAPI COleDateTime::GetCurrentTime() throw()
{
	return COleDateTime(::_time64(NULL));
}

nothing happens, only after returning from this function it starts showing m_status invalid

Did you step in the ctor COleDateTime(::_time64(NULL))?
