Hi,

I have a button on a form which when clicked will open up a save dialog box for the user to save the contents (text) of a memo to a file. What I want to know is, how do I set it up so that it automatically wants to save the file as type .txt ??

Thanks,

D.

OPENFILENAME is used to send paramethers to the get filename dialogs.

OPENFILENAME parameter lpstrDefExt

or possibly

OPENFILENAME ofn; // common dialog box structure
ofn.lpstrFilter = "text\0*.txt\0All\0*.*\0"
ofn.nFilterIndex = 1; // Default extn filter from above list
GetSaveFileName(&Ofn);

Here ya go,

CFileDialog SaveDlg(FALSE, "txt", ".txt", OFN_HIDEREADONLY, "Text Files (*.txt)|*.txt|All Files (*.*)|*.*||");  
      
SaveDlg.m_ofn.lpstrTitle = "Save as text"; // Set the dialog title.
SaveDlg.m_ofn.lpstrInitialDir = "C:\\"; // Set the default directory.
   
// Display the Save file dialog.
if(SaveDlg.DoModal() == IDOK)          
{
   // check the extension to make sure its ok
   CString Extension = SaveDlg.GetFileExt();
   if(stricmp(Extension, "txt") != 0)
   {
      AfxMessageBox("You must select a valid txt filename.", MB_OK, MB_ICONSTOP);
   }
}
