If you initialize csDuration with some acceptable string, such as _T("24"), for instance, then, maybe, it would work.

With COleDateTime, you have to use the ParseDateTime method, specifying correctly the lcid parameter.
For instance (I assume your date formats are compatible, respectively with US and Italian lcids, I don't know if it is correct)

COleDateTime firstDate, secondDate;
 firstDate.ParseDateTime(_T("4/2/2008 2:56:50 pm"), 0, MAKELCID(MAKELANGID(LANG_ENGLISH,SUBLANG_ENGLISH_US),SORT_DEFAULT));
 secondDate.ParseDateTime(_T("2/4/2008"), 0, MAKELCID(MAKELANGID(LANG_ITALIAN, SUBLANG_ITALIAN),SORT_DEFAULT));

 if ( firstDate > secondDate)
 {
   //...
 }

Hi..
Actually i have 3 dates..
1) ST_DATE
2) END_DATE
3) MailDate
ST_DATE and END_DATE i read from config file i.e in the format mm/dd/yyyy..
Example
ST_DATE=4/1/2008.
END_DATE=4/2/2008.

MailDate i read from mails....i.e in the format mm/dd/yyyy hh:mm:ss pm

Example
MailDate= 4/2/2008 2:56:50 pm...

Now i want to display the mails which come from ST_DATE and END_DATE..
I need to check

if(maildate >= ST_DATE) && (mailDate <= END_DATE)....

I think you got me....
thank you

And what is the problem (I mean your sign asserts you're experienced)?
for instance

COleDateTime startDate, endDate, mailDate;
DWORD lcidUS = MAKELCID( MAKELANGID( LANG_ENGLISH,SUBLANG_ENGLISH_US), SORT_DEFAULT);
DWORD lcidIt = MAKELCID( MAKELANGID( LANG_ITALIAN, SUBLANG_ITALIAN), SORT_DEFAULT);


startDate.ParseDateTime(_T("1/4/2008"), 0, lcidIt);
endDate.ParseDateTime(_T("2/4/2008"), 0, lcidIt);
mailDate.ParseDateTime(_T("4/2/2008 2:56:50 pm"), 0, lcidUS);

if ( mailDate >= startDate && mailDate < endDate)
{
  // mailDate is between startDate and endDate
}
else
{
  // mailDate is NOT between startDate and endDate
}

You're wrong. Comparison it's working well. If you need all the emails of April 2th (for instance) then you have to do something similar to:

startDate.ParseDateTime(_T("2/4/2008"), 0, lcidIt);
endDate.ParseDateTime(_T("3/4/2008"), 0, lcidIt);
mailDate.ParseDateTime(_T("4/2/2008 2:56:50 pm"), 0, lcidUS);

if ( mailDate >= startDate && mailDate < endDate)
{
  // mailDate is between startDate and endDate
}
else
{
  // mailDate is NOT between startDate and endDate
}

Since startDate actually represent "02/04/2008 00:00:00" and endDate is "03/04/2008 00:00:00".

Hi..
If i compare only once

i.e if(cMailDate < startDate)
its working properly..

but i compare

if(cMailDate <= startDate && cMailDate > endDate)
its not working..

I feel somewhere that in mailDate format is mmddyyyy hh:mm:ss
wheteher time is making problem for comparision.

thank you

Of course. it should be

Hi...

startDate =4/1/2008
endDate=4/3/2008
mailDates = 4/2/2008 7:26:33 pm..

my code is..

/////////////////////////////////////////////////////////
if (mailDate > firstDate && mailDate < secondDate)
{
AfxMessageBox("mails are between startDate and endDate");
}
else
{
AfxMessageBox("mails are not between startDate and endDate");
}
///////////////////////////////////////////////////////////

I should get the message as "mails are between stdate and enddate"

I am getting no mails.

Sorry, I misunderstood the date formats you're using. if all your dates use the mm/dd/yyyy format (regardless about time) then you've to use always the US format, i.e.

COleDateTime startDate, endDate, mailDate;
DWORD lcidUS = MAKELCID( MAKELANGID( LANG_ENGLISH,SUBLANG_ENGLISH_US), SORT_DEFAULT);

startDate.ParseDateTime(_T("4/1/2008"), 0, lcidUS);
endDate.ParseDateTime(_T("4/3/2008"), 0, lcidUs);
mailDate.ParseDateTime(_T("4/2/2008 7:26:50 pm"), 0, lcidUS);

if ( mailDate >= startDate && mailDate < endDate)
{
  // mailDate is between startDate and endDate
}
else
{
  // mailDate is NOT between startDate and endDate
}

Hi All,
I am trying to display the total physical memory of my system. I used GlobalMemoryStatus() API. After rounding the value I get 447 MB. But, the system properties show the RAM as 448 MB. Does anyone have an idea why we get such a difference and how it could be overcome?

Thank you,

Visual Studio 6 had an Export Makefile option but as I am now using Visual Studio 2005 I cannot find this option, has it gone?

Does anyone know what is the method to generate a Make file if you wnat to port your code from Windows to a Unix platform?
