SYMPTOMS
In an application developed for the Microsoft Windows environment using a
common dialog box and a dialog box hook function, the hook function is
unable to access global or local variables even though it receives
messages.
CAUSE
Because the hook function is not exported in the application's module
definition (.DEF) file, the hook function's data segment is not set
correctly when functions in the common dialog box library (COMMDLG.DLL)
call the hook function.
RESOLUTION
Modify the .DEF file to list the hook function in the EXPORTS section.
STATUS
This behavior is by design.
