Inter Process Communication with MSFlexGrid-ctl

I need to retrieve items from an MSFlexGrid-control within a separate app running on my PC.
For the ListView-control I have got the VB6-code on this forum doing just that - http://vbforums.com/showthread.php?t...t+ListView+app) - using ReadProcessMemory() and WriteProcessMemory().
Can the ListView-code be adapted for MSFlexGrid?
If not, - is it possible to f.ex. inject a dll into the other process that will traverse the items of the MSFlexGrid-control at regular intervals (typically every second) and write the contents to some shared memory where it can be retrieved by MyApp. Can VB6 be used for this?
