Explorer-Style Control Identifiers
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.
