.NET Forum / Visual Studio.NET / IDE / February 2007Disabling "Just my code" changes Debug|Exceptions dialog
Normally, the dialog box displayed by Debug|Exceptions has 3 columns: Name, Thrown, and User-unhandled. However, in my VB.Net project (Visual Studio 2005 SP1), if I disable "Just My Code" (under Tools|Options|Debugging|General), then the Debug|Exceptions dialog no longer shows the "User unhandled" column. Can anyone suggest a reason why this might be happening? Hi Bob, Thanks for your post. I have reproduced this issue. The User-unhandled column will only appear in Exception dialog when we enable "Just My Code" option in Tools|Options|Debugging|General. As far as I know, "user-unhandled" column is used for determining which user-unhandled exceptions you want to break on. If you disable the "Just My Code" option, all exceptions will be handled. For this reason, we need not to determine which exception we want to handle. Please feel free to reply me if you have any further issue. I'm glad to work with you. Best regards, Wen Yuan Hi Wen Yuan, I don't get it. As I understand it, enabling "Just My Code" prevents me from stepping into code that meets any of several criteria (optimized, no symbols, etc.). It also prevents the debuger from breaking in code that meets the "not my code" criteria if I click on the "break" button. What's the connection between that behavior and whether or not I want the debugger to break when a particular exception is unhandled? > Hi Bob, > Thanks for your post.

So debugger will break in the following cases, if you disable user-unhandled then no break happens. Non-user frame1 <--- exception thrown here User frame1 User frame2 Non-user frame2 <-- exception caught here User frame1 <-- exception thrown here Non-user frame1 Non-user frame2 <-- exception caught here User frame2 Non-user frame3 User code - have symbols + is unoptiomized + no non-user attributes The idea is that user may want to write a handler for the exception in these cases to provide a better error message and continue for instance instead of letting the exception be handled by a generic handler. Please feel free to reply me if you have anything unclear and we will follow up. Have a great day. Best regards, Wen Yuan Thanks Wen Yuan! It finally occurred to me to press F1 while I was staring at the Debug|Exceptions dialog. That took me to an MSDN Help page that cleared up my (bone headed) confusion. I was missing the basic concept that the user-unhandled column is equivalent to "Unhandled in "My Code" (as in "Just My Code"). So obviously, turning off "Just My Code" turns off that column. I would imagine that I'm far from the only user who has seen this dialog and not understood what that column really does. The dialog really should be redesigned to say "Unhandled by My Code" (IMHO). > Hi Bob, > Thanks for your reply. [quoted text clipped - 25 lines] > Best regards, > Wen Yuan Hi Bob, Thanks for your reply. The name of column ("user-unhandled") is really confusable. But I'm very glad to hear you have understand it. Please feel free to reply me if you have any further question. I'm glad to work with you. Have a great day.
