Yong,
There is a section in Jeffrey Richter's book "Advanced Windows" about
this.
1. In your main file, add:
#pragma data_seg(".SharedData")
DEFINE ALL YOUR SHARED DATA
#pragma data_seg()
2. In your .DEF file, have the following lines (note that the segment
name you give here should match the one in the application's main
file):
SEGMENTS
.SharedData shared
