You could be using some uninitialized variable in your code for the second time. Did you try and debug your code?

I've developed an application using Visual C++ 2005. This application showed me error at linking. The errors are:

Wouldn't this always return 31?

if( objDate.GetStatus() == COleDateTime::invalid ) fails for some reason so the function always returns 31. I recall seeing this code somewhere in MSDN (??? probably). Used it some time back.
[modified]A quick look at MSDN gives me this:If you call GetStatus on a COleDateTime object constructed with the default, it will return valid
Eg:The status of this is 2000, 2, 31 = valid ???

But I am calling SetDate() after the construction of COleDateTime object. Suppose if you set a date as objDate.SetDate( 2008, 2, 30 ); The date will be invalid and if( objDate.GetStatus() == COleDateTime::invalid ) will return true.

I just tried this bit of code and it always returns me 31. even the parameters to the function when passed as 2000,2 returns 31. ??? Any reasons. I modified my last post to include this.
BTW does this code execute as expected at your end.

Same here [WinXP SP2]. but it always returns 31. Will try and find the reason behind this behaviour and get back if possible.
