How to trouble shoot a "Application Exception"?

I have an application I created called "JpegViewer.exe". It simply loads a
Jpeg file and displays in on the screen. It works great, in my lab.



When I am using it at a customer site, things change. Occasionally, it
blows up with an Application Exception. It seems to only die at the
customer site



This can only be duplicated on the machines at a client site. I cannot
reproduce this "Bug" in my lab.



I am 100% confident there is no programatic bug the the JpegViewer.exe
program, because of the testing I have done. Again it works great in my lab
(it Works for me!).



I think there is something funny with the customer environment, but have
nothing solid to try. Any suggestions/help is greatly appreciated!





(This is how I am calling "JpegViewer.exe", no errors are caught by the
try,catch block)



Public Shared Sub LaunchApplication(ByVal Command As String)

Try

Shell(Command, AppWinStyle.NormalFocus)

Catch ex As Exception

UpdateStatus("LaunchApplication - ERROR - Could not launch
task.")

End Try

End Sub




(This is what shows up in the event log at the client site - again, only
sometimes - but when it does, my Jpegviewer program dies a horable death
(Jpegviewer doesnt even seem to actually do anything).)



Application exception occurred:

I'd recommend inserting some more specific error handlers, but you can use
something like this ... http://www.knowdotnet.com/articles/eventlog.html

This might help too.

Hello,

Thanks for your post. As I understand, a third-party application
JpegViewer.exe crashs on a specific system. Please correct me if there is
any misunderstanding. I agree with William's reply. In addition, I'd like
to share the following information with you:

1. I suggest you to check the underlying DLLs that are required by
JpegViewer.exe (by using Dependency Walker) and compare the version of them
on your machine with them on the system that fails to work. You can
download it at the following link:

Dependency Walker 2.1
http://www.dependencywalker.com/

2. Since JpegViewer is a third-party product, you can also contact its
vendor and see if there is any known issue.

Hope this helps.

gregory_may said:
I have an application I created called "JpegViewer.exe". It simply loads a
Jpeg file and displays in on the screen. It works great, in my lab.



When I am using it at a customer site, things change. Occasionally, it
blows up with an Application Exception. It seems to only die at the
customer site



This can only be duplicated on the machines at a client site. I cannot
reproduce this "Bug" in my lab.



I am 100% confident there is no programatic bug the the JpegViewer.exe
program, because of the testing I have done. Again it works great in my lab
(it Works for me!).



I think there is something funny with the customer environment, but have
nothing solid to try. Any suggestions/help is greatly appreciated!





(This is how I am calling "JpegViewer.exe", no errors are caught by the
try,catch block)



Public Shared Sub LaunchApplication(ByVal Command As String)

Try

Shell(Command, AppWinStyle.NormalFocus)

Catch ex As Exception

UpdateStatus("LaunchApplication - ERROR - Could not launch
task.")

End Try

End Sub




(This is what shows up in the event log at the client site - again, only
sometimes - but when it does, my Jpegviewer program dies a horable death
(Jpegviewer doesnt even seem to actually do anything).)



Application exception occurred:

Hello,

Thanks for your update. I reviewed your code carefully, I did not find any
obvious problem. Now I'd like to share the following information with you:

Since the problem only occurs on your client's machine, while it works
properly on your system, I suspect that the problem may be caused by the
system configuration. What's the version of operating system and its
service pack, .NET Framework version on the problemmatic system?

As stated in my previous post, please compare the versions of underlying
DLLs in Dependency Walker.

In addition, to narrow down the problem, I recommend you show a MessageBox
to display the content of Call Stack when the exception is caught.

I look forward to your response.

Thanks for your help!!!

I will be at the client site friday to verify some of these items.
I believe the client is running Win2k Service Pack 5 and .Net 1.1

Just an odd note: If I execute JpegViewer.exe from the command line or
desktop i get no errors on the client machine!!!! It only happens
pieriodically when I execute it from a Shell Command (From another vb.net
application).

I suspect some wacky resource constraint. I am going to try and execute the
program differently to try and get another layer of resources. I was
thinking of something like:
Shell(cmd /c"JpegViewer.exe") or
Shell(JpegViewer.VBS) (This would in tern call
JpegViewer.exe)

I will also try:

* Reinstall .Net on a few of their boxes.
* See if I can uninstall some of their applications including:
Norton AntriVirus software, Carbon Copy, and Altrus Software
Mangement.
* Try your resource walker.

Because I dont really "See" what looks like a .Net exception, I dont know
where to put the message box. My program doesnt even bring up the form. It
really looks like a "Windows" exception. Its just a small dialog that says
something like:
"The application JpegViewer.exe caused an error in MsCorb.dll.
Windows has shut down the application."
(The words are wrong. I will get the exact message on friday).
 
I have been thinking over your Dependency Walker. I should probably try
this first.

Thanks again for your help!

My install blew up today. I misplaced a DLL (MSGINA) and the machines have
to be re-imaged!!

So, I will have to try again wednesday. Sorry for the delay.
