From the MSDN[^]

It looks like you just call it with a path and the ID of your control. It seems to know how to populate it.

here's a code sample from the MSDN

// If pDialog points to a CDialog object with a combo box<br />
// with the identifier IDC_COMBO1, this call will populate<br />
// the box with only the non-hidden subdirectories in the root<br />
// directory of the C:\ drive. <br />
<br />
TCHAR szPath[MAX_PATH];<br />
_tcsncpy_s(szPath, MAX_PATH, _T("C:\\"));<br />
pDialog->DlgDirListComboBox(szPath, IDC_COMBO1, 0, DDL_EXCLUSIVE | DDL_DIRECTORY);<br />
<br />
// Note that the first argument is a string and not a string <br />
// literal. This is necessary because DlgDirListComboBox <br />
// modifies the supplied string. Passing a string literal <br />
// will result in an access violation.

I found this: see this[^]

I bet you have to deal with UAC to find out what you want on Vista.

Yes it is!

OSVERSIONINFO osVersion;

memset( &osVersion, 0, sizeof(osVersion) );
osVersion.dwOSVersionInfoSize = sizeof(osVersion);

GetVersionEx( &osVersion );

bool isVista = (osVersion.dwMajorVersion==6) && (osVersion.dwMinorVersion==0);
