You can use GetDays () function of COleDateTimeSpan class.
If you divide Days by 30, you will get the approximate months.

The other option is to use int GetMonth() function of COleDateTime variables.
This will return the month value in int.
If you subtract the values, you can get the approximate month difference. (But you have to take care of the year also).

COleDateTime has GetMonth, GetDay and GetYear methods that would allow you to determine the difference in real, calendar months:

int GetMonthsBetween(COleDateTime a, COleDateTime b)
{
   if (a < b) return GetMonthsBetween(b, a);
   const int aMonths = a.GetYear()*12 + a.GetMonth();
   const int bMonths = b.GetYear()*12 + b.GetMonth();
   const bool needToRoundDown = (aMonths>bMonths) && (a.GetDay() < b.GetDay());
   return (aMonths - bMonths) - ( needToRoundDown? 1 : 0 );
}

This will round the month count down if necessary. For example, consider if a = June 12th and b = May 25th - you can see there's less than one full month between them.

Call Create() function of the property sheet and pass the address of the dialog class as parent window.

You can use the function - GetDiskFreeSpaceEx ().

Following are the reasons for Error C2065 from MSDN.

1. You are compiling with a debug version of the C runtime, declaring a Standard C++ Library iterator variable in a for loop, and then trying to use that iterator variable outside the scope of the for loop. Compiling Standard C++ Library code with a debug version of the C runtime implies /Zc:forScope. See Debug Iterator Support for more information.

2. You may be calling a function in an SDK header file that is currently not supported in your build environment.

3. Omitting necessary include files, especially if you define VC_EXTRALEAN, WIN32_LEAN_AND_MEAN, or WIN32_EXTRA_LEAN. These symbols exclude some header files from windows.h and afxv_w32.h to speed compiles. (Look in windows.h and afxv_w32.h for an up-to-date description of what's excluded.)

4. Identifier name is misspelled.

5. Identifier uses the wrong uppercase and lowercase letters.

6. Missing closing quote after a string constant.

7. Improper namespace scope. To resolve ANSI C++ Standard Library functions and operators, for example, you must specify the std namespace with the using directive. The following example fails to compile because the using directive is commented out and cout is defined in the std namespace:

The CreateTimerQueue() will only be available only if _WIN32_WINNT is greater than or eual to 0x0500. So in the project settings->c/c++->Pre processor definition put _WIN32_WINNT=0x0500

or in the stdafx.h define the macro as

#define _WIN32_WINNT 0x0500

That function requires windows 2000 or above. So take Project settings, C/C++ tab and add _WIN32_WINNT=0x0500 to the preprocessor definitions. Hope at this time, it will compile. Wink | ;)

VC++ 6.0 tp 9.0 porting issue with CDataExchange

Hi All,

When i am porting my application VC++ 6.0 to VC++ 9.0 in the following piece of code i got the error

error C2039: 'm_hWndLastControl' : is not a member of 'CDataExchange'
else if (pDX->m_hWndLastControl != NULL && pDX->m_bEditLastControl)
{
::SendMessage(pDX->m_hWndLastControl, EM_LIMITTEXT, maxChars, 0);
}

When i had a look at the CDataExchange class the member hWndLastControl is emoved and a new member called m_idlastcontrol is introduced.

i can use the pDX->m_hWndLastControl in the comparison, but SendMessage nead a HWND. How can i get the HWND from m_idLastControl?

Is there any API to get the handle of a control from its ID?

Thank you all for the support.
