Have the constructor of your CMyFileSaveDlg class to check the version of OS
installed and st the size for the OPENFILENAME structure accordingly.
DWORD dwSize = 0;

OSVERSIONINFO vi;

ZeroMemory(&vi, sizeof(OSVERSIONINFO));

vi.dwOSVersionInfoSize = sizeof(OSVERSIONINFO);

::GetVersionEx(&vi);

if (vi.dwMajorVersion >= 5)

{

dwSize = sizeof(OPENFILENAME);

}

else

{

dwSize = OPENFILENAME_SIZE_VERSION_400;

}

m_ofn.lStructSize = dwSize;

Hi,
We ran into this problem when trying to move to Visual Studio 2008 from
Visual Studio 2005. We have a custom class derived from CFileDialog to
handle
OnTypeChange() and in that call we try to set the file name directly by
calling SetControlText() as below:

void MyFileSaveDlg::OnTypeChange()
{
  .
  .
  SetControlText(edt1, fileName);
  .
  .
}

The SetControlText() call causes crash when application is built with
Visual
Studio 2008 is run on Vista. Although the documentation for new version of
CFileDialog states that the Control ID system is different in Vista but it
doesn't point where should one look to update the references. In stdafx.h
we
have defined our WINVER to be 0x501.

My question is how can we fix that so that our application can run on XP
and
Vista but built with Visual Studio 2008.

Thanks.
