Help required on usage of PESetNthTableLocation

[hemanth]

I have created a VB application (BackEnd : Access) which uses crystal reports for its reporting. I am using Dll function calls from CRPE32.dll and not Crystal Report OCX. I am encounteringa problem with the following two function calls.
1. PEGetNthTableLocation
2. PESetNthTableLocation
I think These two calls are used to get/set the database path for the reports. (Whenever i use these calls they are generating General Protection Faults, probably due to improper parameter passing)
Can U help me out in this regard.

Thanks in Advance
