Out of Memory - Problem.. Very Much Frustrating

Hi,

I am using Visual Basic 6.0 with MS - ACCESS for my application. I am using latest Sheridian Controls , VCON ( Video Conferencing Controls ) , LEAD Tools Third Party Controls in my Application. My system is configured with 128 MB RAM , 8.3 GB HDD. When my application is in use I am getting this error. I have done
thorough code walkthrough , making the database objects to be closed whenever not required by Closing them and setting to nothing. I have done all possible attempts to resolve this problem.. But I am unable to identify where is the problem..

My friend was arguing on one concept of Windows regarding the User Heap and GDI Heap .. as there are some memory limitations on some specific data structures .. Is there any possibility that the GDI heap is using all the memory resources and leaving no memory for other resources..

Please let me know this immediately..

Most Urgent

Regards
