How to debug exe at client place.

Hey sorry for late reply. In those cases where we cannot debug what is happening at the client place the best option is to use the logging mechanism.

Add tracing code to each of the conditional statements in your code and configure the application in such a level that you define the logging level. If you set the level to trace then your application should write all the events or conditions that are being executed in a detailed manner. If we configure our application only to log errors it should only logging when there is an error.

Whenever there is some issue in the production set the configuration to trace each condition and get the log file from the production server to check what is happening. so you need add logging in very detailed manner so that without debugging you should be identify the issue.

First of all thnx to reply my question.

ok let me give u  actual scnerio

my windows application is connecting quickbook company file. when we test, we r testing in our sample based company file or created by us. not a actual file.

so when i have installed setup in client place it works fine but after 2 3 days client got one object reference error.
