Hi,
i developed an application in c# and using mysql as back end. I have used ADODB for connecting to DB. I use DSN for communicating.

Now i have problem i have to install at my clients place where there are 3 machines interconnected (LAN). out of which 1 is XP, 1laptop with win7 and other Desktop with win7. Every thing working perfect on Laptop and XP machine but when i try to run Application on Desktop with win 7 it give following error. Actually i am able to connect to this desktop with win7 (this is working as server) from other two machines. Data is getting inserted properly. So i dont understand what is the problem with this server machine. I am getting following error message.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:
<configuration>
    <system.windows.forms jitdebugging="true" />
</configuration>

When JIT debugging is enabled, any unhanded exception will be sent to the JIT debugger registered on the computer rather than be handled by this dialog box.

It will be gr8 help if any one rectify my problem. I would like to mention here is that i have not at all used this "Socket" related code in the whole project. So please guide me. I am absolutely stuck up due to this problem.

Thanking you
