I have created a Excel Addin to review the Analtyical Reports in the Excel.

When the user is trying to get the data from the server he is getting an
error message though i am able to perform the operation successfully on my
env.
Error Message:
Run-time error '-2146233079 (80131509)':
The underlying connection was closed: The connection was closed unexpectedly.

As we clik on the ok button for the above error message pop-up, i am getting
an another error message with the following details.
It has two buttons defined on the pop-up:- Cancel and Continue.

Then this error message appeared:
Microsoft .NET Framework box:
Unhandled exception has occurred in a component in your application. If you
click Continue, the application will ignore this error and attempt to
continue.
Exception from HRESULT: 0x800A9C68

2a) Within the box there was a Details drop down:
See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

************** 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 unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.

Please help me on this issue.

Thanks,
Sandeep
