ActiveX EXE multi threading and global variables in modules

[axisdj]

Hello Group,

Over the last few years I have made an effort to fully understand how vb6 activeX exe achieve multi threading for vb6 apps.

My insight became a little more clear when I needed to move a http call to a thread this weekend. I discovered first hand that VB6 keeps two copies of the global variable ( to be thread safe I assume)

So to get my code working I had to sync the threaded class global with the main gui thread global variable ( via an event from class). It was really amazing to see that they were actually two separate address locations. The global was declared in a Module.

For the GURUS here please correct me if I am wrong, and maybe add more insight to this.

thank you!
