AFAIK, user can type in any name and the file dialog will accept it, you can detect that by deriving your own class from CFileDialog and override some of the members (see the documentation) Originally,
hooking was the proper method; but now override is the way to go.Watched code never compiles.

Have you considered something like:
CFileDialog fileDlg(TRUE, NULL, NULL, OFN_PATHMUSTEXIST | OFN_FILEMUSTEXIST | OFN_HIDEREADONLY, _T("Text Files(*.txt)|*.txt||"), this);
do
{
if (fileDlg.DoModal () == IDCANCEL)
return;} while (fileDlg.GetFileExt() != _T("txt"));
SetDlgItemText(IDC_PATH, fileDlg.GetPathName());
[edit] Alain's suggestion is a much better solution. [/edit]

Hi, For custom file name validation derive from
CFileDialogand override CFileDialog::OnFileNameOK[^]. This function allows you to reject a filename for any application-specific reason. cheers, ARWhen the wise (person) points at the moon the fool looks at the finger (Chinese proverb)
