Question

I have created a vb.net program and released it to the customer. They are running the exe and at times the program crashes unexpectedly and display the message: “… has encountered a problem and needs to close”

I know I should have added code to handle the exception, but is there a way that I can find out which line in the program caused the error? What is generally as good way to track errors in a program after it has been released?

Thanks

for this kind of i-don’t-know-where-to-look issue, i trapped exception at application level with the Application.DispatcherUnhandledException event :

http://msdn.microsoft.com/en-us/library/system.windows.application.dispatcherunhandledexception.aspx

and then in the event handler i get the StackTrace and display it in a MessageBox / dump it in a file, along with the exception.Message.

Next i offer the user the choice to re-launch the application.
