We don't have magicaly abilities to find out what is wrong with you code without looking at it. If you need help then post with more details about what exactly are you doing with small code snippets.

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:
HelloWorld.obj : error LNK2019: unresolved external symbol "__declspec(dllimport) protected: virtual __thiscall dtABC::Application::~Application(void)" (__imp_??1Application@dtABC@@MAE@XZ) referenced in function __unwindfunclet$??0HelloWorld@@QAE@ABV?$basic_string@DU?$char_traits@D@std@@V?$allocator@D@2@@std@@@Z$0

int GetNumberOfDays( int nYear, int nMonth )
{
COleDateTime objDate;
int nDay = 29;
for( ;nDay < 32; nDay++ )
{
objDate.SetDate( nYear, nMonth, nDay );
if( objDate.GetStatus() == COleDateTime::invalid )
{
break;
}
}
return --nDay;
}

Wouldn't this always return 31?

 How? Can you explain?

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.

yes. it returns 29.
Is it because of some OS environment problem ?I am running on windows XP with SP2.

|

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