The system requires the hook procedure to process all messages intended for the custom dialog box and therefore sends the same window messages to the hook procedure as to any other dialog box procedure.
The hook procedure is responsible for initializing these controls and retrieving values from the controls when the dialog box is closed. The default dialog box procedure handles messages for all the controls in the default dialog box, but the hook procedure receives the notification messages for user actions on these controls as described in Explorer-Style Hook Procedures.
The Windows Software Development Kit 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 dialog boxes 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.
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. You can customize an old-style Open or Save As dialog box by providing an OFNHookProcOldStyle hook procedure that receives messages or notifications intended for the default dialog box procedure. You can also provide a custom template to use in place of the default template.
The hook procedures and templates used with the old-style dialog boxes are similar to those used with the other common dialog boxes. Create the custom template by modifying the default template specified in the Fileopen.

The hook procedure receives notification messages sent from the common dialog box and messages for any additional controls that you defined by specifying a child dialog template. The hook procedure does not receive messages for the standard controls of the default dialog box.
The system uses the custom template to create a child dialog box. The template can define additional controls, and can specify the location of the cluster of standard controls. The custom template does not replace the default template. The hook procedure receives all messages sent to the dialog box, including messages for the standard controls and any custom controls.
