BrowseHookProc( HWND hwnd, UINT message, WPARAM wParam, LPARAM lParam )

/*++

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

Routine Description:

Presents a common file open dialog that contains only the directory
tree. The use can select a directory for use as a storage location

Arguments:

szCurrDir - current directory

Return Value:

TRUE - got a good directory (user pressed the OK button)
FALSE - got nothing (user pressed the CANCEL button)

the szCurrDir is also changed to have the selected directory.
