I have a problem with my VB APPLICATION.

it is terminating automatically, before terminating this error is flashed
---------------------------------
VB6.exe - Application error
The instruction at "0x007015c8" referenced memory at "0x007015c8". The memory could not be "read".
Click ok to terminate & cancel to debug..

I will be greatfull to the person who can solve this problem.
