SystemParametersInfo error

[ovi]

Hi all,

I am trying to port an application from VC++ 6.0 to Visual Studio 2008. The code is not written by me.

When function SystemParametersInfo() is invocked it returns FALSE, but when I check the error with GetLastError(), return value is 0 (zero). Anyhow, the behaviour is like the function had failed.

The same code works properly when compiled with VC++ 6.0

What I am doing wrong?
Thanks,
ovi

There are various params to that function that are specific to the version of Windows. Post the code that returns FALSE

Hi Fordy,

Thanks for interest. Here is the piece of code with problems

   int error =0;      //for debug
   TCHAR errmes[50];  //for debug

   NONCLIENTMETRICS ncm;
   ncm.cbSize = sizeof(NONCLIENTMETRICS);
if(SystemParametersInfo(SPI_GETNONCLIENTMETRICS, sizeof(NONCLIENTMETRICS), &ncm, 0))
	{
		AfxMessageBox("SytemParametersInfo = OK"); //for debug

	}
	else
	{
	   error = GetLastError();
	   sprintf(errmes,"SystemParametersInfo ERROR\nLast Error = %d",error); //for debug
 	   AfxMessageBox(errmes);
	}
      memcpy(&m_Logfont, &(ncm.lfMessageFont), sizeof(LOGFONT));

Try set the size of the struct to "sizeof(NONCLIENTMETRICS) - sizeof(ncm.iPaddedBorderWidth);"

There's an addition to that struct (iPaddedBorderWidth) that seems to screw it up between Vista & XP

Thanks for the hint. Unfortunatelly, it doesn't work. It behaves exactly the same.
Btw, I am using Windows XP.
