Routine Description:
Hook procedure for directory browse common file dialog. This hook
procedure is required to provide help, put the window in the
foreground, and set the edit so that the common file dialog dll
thinks the user entered a value.
Arguments:
hwnd - window handle to the dialog box
message - message number
wParam - first message parameter
lParam - second message parameter
Return Value:
TRUE - did not process the message
FALSE - did process the message
