.NET Runtime error

Hi everybody,

I'm facing an unidentified problem related to .NET framework. On event
viewer, the following message is logged:

Source: .NET Runtime 2.0 Error Reporting
Category: None
Type: Error
EventID: 5000
Description: EventType clr20r3, P1 pos.exe, P2 3.3.2636.21715, P3 4600f8b6,
P4 system, P5 2.0.0.0, P6 4333ae87, P7 3246, P8 273, P9
system.formatexception, P10 NIL.

This problem seems to be happened in ramdom during the execution of
application. When this problem occurrs, my application have to quit and
restart again. My application is compiled by VB.NET 2005. I have no idea
the cause of this problem.

The runtime environment is:
* Intel P4 2.0G with 512MB
* Windows XP Professional with SP2 and latest pathces
* SQL Server 2000 Desktop edition with latest patches
* .NET Framework 2.0 with latest patches

Thanks a lot for your attention and kindly advice!

Regards,
James Wong

Hi James,

Regarding on this problem, the error message in the eventlog indicate that
System.FormatException is throwed from the application (pos.exe?), is this
the same application you mentioned in your previous thread?

For this exception, it is quite general and hard to determine the exact
cause. For example, functions like string.Format, Console.Write that take a
string format template will probably raise this exception when the template
syntax is incorrect. Or the ADO.NET SqlCommand will also raise this error
during executing of command.

So far for this kind of problem, if you want to troubleshoot it, there are
two common approaches:

1. check all those code will potential raise this problem and add exception
handle there(such as console output, string.Format , SqlCommand execute....)

2. Use some advanced debugging tools to perform live debugging against the
application and capture the exact type of the exception. This is a bit too
complex and generally it is done by the product support team's engineer
when troubleshooting.

Here is a blog article mentioned this:

Hope this helps.

Hi Steven,

Thanks for your reply!

Yes, this error is occurred on the same application as I mentioned in
another thread. I'm still struggling with these "unmanged" problems. In
fact, my previous version is compiled by VB.NET 2003 and works fine. In
this version, the basic logic of printing and other functions don't change
much. So I wonder whether some behavior of .NET framework 2.0 changes from
ver 1.1. Anyway, I'll trying to add some codes to get error details.

Regards,
James Wong

Thanks for your reply James,

Such general exception does be hard to troubleshoot, that's why we commonly
use debugging tools to perform live debug or dump analysis for these cases.
Anyway, if you have got any progress or if there is anything we can help,
please feel free to post here.
