Detail View in FileOpen Dialog

Environment: VC5 WinNT4/Win2000 ( Should work with VC6 and other Win platforms)

I wanted to have the standard file open dialog startup in
detail view by default. The code gurus showed me how to
customize the file open dialog but not a single article described
how to start the fileopen dialog in detail view. I saw many
people had specifically asked the same question but there
were no answers. So, I set myself to figure out how to do this.

You can use any of the excellent articles describing how to extend
the standard fileopen dialog as a starting point. Then add a few lines
of code presented below to your extended dialogs OnInitDialog() method
and presto! the fileopen dialog will have the detail button ( view)
activated when it is shown.

The Magic, as you can see is done by posting the WM_COMMAND message
to the parent of the extended fileopen dialog ( which is really the original
file open dialog) with the ID (40964) of the push button for detail
view. This simulates a click of the detail button and the detail view
is activated for you.

The trick is simple. But I must warn you that the id of the push
button for the detail view was not documented – at least I did not
find it anywhere. I used spy++ tool (comes with VC5) in message mode
to discover its id. I have tested this on WinNT and Win 2000. It may
not work on other platforms.


BOOL MyFileOpenDialog::OnInitDialog()
{
CFileDialog::OnInitDialog();

// heres the code to enable detail view

CWnd *parent = GetParent();
if ( parent != NULL ) {
parent->PostMessage(WM_COMMAND, 40964, NULL);
}

// thats it !!

return TRUE;
}
