CFileDialog Files of Type selections

Environment: VC++ 4.2-flat, Windows NT 4.0
After the construction of the explore style dialog box upon a change of the
File of Type selection I wish to display the selected *.ext in the file name
edit box. The default behavior of this dialog leaves the file type edit box
blank after a new File of Type selection. Must I construct a new template or
is there a way to get the resource ID of the edit box so as to change the
text I would like to ensure that if I hard code this ID in that microsoft
does not change it in the future :-). I would like my file open dialog to
function like the file open dialog in Word.
Thanks in advance......
Sincerely,
Tony D. Abel

Take a look at CFileDialog::OnTypeChange for access to the notification.
As for the control IDs, they're documented in the Win32 Programmer's
Reference. I'm getting it through books online, and a search for the
title "Explorer-Style Control Identifiers" will show you what you need.
>From there you can also get to the documentation for CDM_SETCONTROLTEXT.
The documentation is all there, but sometimes a bit scattered. You need
to make judicious use of the Books Online (or MSDN) query capability to
spelunk for all of the info you need. :-)

Hi Tony,
I found this in the SDK docs in MSDN ...
"The Win32 SDK provides the default dialog box template for the old-style
dialog boxes, but does not include the default template for the Explorer-
style dialog boxes. This is because the Explorer-style dialogs allow you to
add your own controls but do not support modifying the template for the
standard controls. However, in some cases, you may need to know the control
identifiers used in the default templates. For example, the CDM_HIDECONTROL
and CDM_SETCONTROLTEXT messages require a control identifier.
"The following table shows the identifiers of the standard controls in the
Explorer-style Open and Save As dialog boxes. The identifiers are constants
defined in DLGS.H and WINUSER.H.
Identifier Description
cmb2 Drop-down combo box that displays the current drive or folder,
and that allows the user to select a drive or folder to open
stc4 Label for the cmb2 combo box
lst1 List box that displays the contents of the current drive or
folder
stc1 Label for the lst1 list box
edt1 Edit control that displays the name of the current file, or in
which the user can type the name of the file to open
stc3 Label for the edt1 edit control
cmb1 Drop-down combo box that displays the list of file type filters
stc2 Label for the cmb1 combo box
chx1 The read-only check box
IDOK The OK command button (push button)
IDCANCEL The Cancel command button (push button)
pshHelp The Help command button (push button)"
"edt1" looks like the edit control that you want, and it's documented, so
Microsoft won't change it! 8-)
