Is This ODBC connectivity error or VB application error

HI

While Multiple users executing exe of VB with MySQL as database,
error occurs during middle of processing.
I can’t find what type of error it is.Whether this error is DB related or OS
error or MySQL connectivity error.

Here I attached the error file

Its really impossible to say what caused the error, but maybe try upgrading to latest ODBC driver in your dev/test environment and try to reproduce the crash.
