Simply set "Use System Font" in the dialog editor and the dialog will automatically use the default system font.

Then you should use SystemParametersInfo to retrieve information about the message box font and create a font object based on that. Something like this:

NONCLIENTMETRICS ncm;
ncm.cbSize = sizeof(ncm);
SystemParametersInfo(SPI_GETNONCLIENTMETRICS, sizeof(ncm), &ncm, 0);

HFONT hSystemFont = CreateFontIndirect(&ncm.lfMessageFont);

Thank you very much for all the help .. but really not using such code to create the fond..

CreateFont(
		16,                        // nHeight
		0,                         // nWidth
		0,                         // nEscapement
		0,                         // nOrientation
		FW_BOLD,                   // nWeight
		FALSE,                     // bItalic
		FALSE,                     // bUnderline
		0,                         // cStrikeOut
		ANSI_CHARSET,              // nCharSet
		OUT_DEFAULT_PRECIS,        // nOutPrecision
		CLIP_DEFAULT_PRECIS,       // nClipPrecision
		DEFAULT_QUALITY,           // nQuality
		DEFAULT_PITCH | FF_SWISS,  // nPitchAndFamily
		"Tahoma"));                 // Facename

and after creating the font am just using this to set for particular dlg item..

please let me know how can i use this ..

You have to make your mind up... do you want to use the system's message font, or Tahoma?

As previously shown to you, get the NONCLIENTMETRICS structure, contaming lfMessageFont .

Then create a font with it.

CMyDialog dlg (blah);
dlg.m_MyFont.CreateFontIndirect (&ncm.lfMessageFont);

and use it to set your control's font...
BOOL CMyDialog::OnInitDialog ()
{
...
GetDlgItem (IDC_MYCONTROL)->SetFont (dlg.m_MyFont);
...
}

Tada!

about dlls in visual C ++ 6 and Visual C++ 2005

Dear all
I have two programs:
1. the source code of a dll suppose that a.dll
2. the source code of program which uses a.dll suppose b.exe.
both of them were written in vc6 IDE, and both are operational
now I compile the a.dll in visual C++ 2005.
but when I want to use a.dll with b.exe , when I call GetProcAddress to retrieve the address of functions , Null value is returned.
I dont know how to overcome this problem.
If u have any idea please let me know.
I must say that a.dll should be backward compatible , thus it is not possible to change b.exe program.

Check the below two things.

1) Debug the application and when the GetProcAddress returns NULL, put err,hr in the watch window to find the last error occured.

2)Take the dependecy walker and open the dll. In the export section of the dll, check whether the function is exported or not.

I found that I didnt export functions of dll.
But i dont know what dependency walker is.
whould you please let me know about it.
I download a tiny software to see the export list of the dll.

Always keep in mind there's nothing to do with which version of the VC compiler was used to make the dll. Always check for the dependency & exported functions ,that's it.

In addition to the previous (good) answers, you'll want to look up "name decoration", and "extern "C" {" in the search engine of your choice.

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.
