When dealing with custom exceptions, I usually inherit from Exception and then add some fields/properties to my exception class to store some additional info: public class MyException : Exception { public int ErrorCode{get;set;} public MyException() {} } In the above example, the ErrorCode value is stored in the exception...
Since there is no finally clause to the try-catch block in MATLAB, I find myself writing lots of code like the following: fid = fopen(filename); if fid==-1 error('Couldn''t open file'); end try line = getl(fid); catch ME fclose(fid); rethrow ME; end fclose(fid); I find having the fclose function in two places ugly and err...
I am developing a DHTML/Javascript application which relies on some advanced features (DOM manipulation, AJAX, Flash communication, and more). I'm very concerned about functionality -- if problems occur, even after the application is deployed, I want to make sure I know why and how to fix them -- and also, I want to make sure the user is...
I'm coding a simple little class with a single method send an email. My goal is to implement it in a legacy Visual Basic 6 project, exposing it as a COM object via the COM Interop facility. There's a detail I'm finding difficult to resolve, that being how granular should I be at validating parameters. On that light, a thing I'm really n...
Hi, The problem that I am facing is primarily on Exception Handling! When an exception occurs I want to put that data in another log table with the error message. However, in DB2 I am not able to figure out a way to retrieve the corresponding error message for the raised SQLSTATE. PS: I have a stored procedure for this migration and I...
First let me say I have read this useful article thoroughly and am using the SafeThread class from CodeProject. I get the same result whether using Thread or SafeThread. I have reduced my problem down to an app consisting of two forms each with one button. The main program displays a form. When you click that button, a new thread starts...
Hello: I've been thinking about nested try/catch statements and started to think about under which conditions, if any, the JIT can perform an optimization or simplification of the compiled IL. To illustrate, consider the following functionally-equivalent representations of an exception handler. // Nested try/catch try { try { ...
Our WCF services occaisionally spawn a worker thread to handle something that the client doesn't care about. The worker threads do not report any status back to the client. In fact, the service has probably already returned results to the client by the time the thread finishes. One of these background threads recently caused an except...
I have an application hosted on IIS7 running in Integrated mode. I'm handling errors by putting the following into Web.config: <httpErrors errorMode="DetailedLocalOnly" existingResponse="Replace" defaultResponseMode="ExecuteURL" defaultPath="/Error.aspx"> <remove statusCode="500" /> <error statusCode="500" path="/Error....
Simple question: If I've got a generic Error.aspx page in my Shared folder (and the requisite HandleError on my controller). How do I show the exception message that triggered it? This Scott Gu post states that the functionality should be in the default Error.aspx generated with new projects, but that was Preview 4, and I'm assuming tha...
I have seen code like this (actually seeing another person type it up): catch (Exception ex) { string exception = ex.ToString(); } Is this code bad? If so, why? There is an appropriate "chain of catch handlers (eg more specific one above, filtering down to general catch all Exception, but in the string conversion of the Exception,...
Hi All Is there an easy way to log all exceptions in an ASP.NET application? I'm already logging unhandled exceptions through the Application_OnError event, but I want to perform logging even when an exception is handled on a page level. Many thanks. ...
Hello! I have this code: Thread t = new Thread(() => UpdateImage(origin)); t.Name = "UpdateImageThread"; t.Start(); If method UpdateImage(origin) throw an exception, it is necessary to stop thread or it will be stoped after the exception? Thank you! ...
I'm trying to trap any and all exceptions in a C++/CLI app so that I can log and record them (including a stack trace). So far I have some code which looked promising: [STAThreadAttribute] int main(array<System::String ^> ^args) { // Enabling Windows XP visual effects before any controls are created Application::EnableVisualStyles(); ...
I have a Stack object being worked on by multiple threads. One of the threads is a worker thread which performs a pop operation on the Stack object. I wanted to handle the case where the Stack is empty and I see two options try{ Object obj = (Object) d_stackObj.pop(); } catch (EmptyStackException e) { ...} OR if( ! d_sta...
Possible Duplicate: The case against checked exceptions EDIT: It appears I didn't phrase my question correctly, and I can understand the frustration. I'm looking for some information that explains where I should use checked exceptions and where I should not use it. Most of the information on this subject is one sided - love/ha...
Sometimes in an application, one might compare the Message text of an exception. For instance, if ex.Message.Contains("String or binary data would be truncated") then a MessageBox will be displayed for the user. This works when testing on an English-language Windows system. However, when the program is run on a system with a differen...
This is a basic string reverse program and I want to do some level of exception handling in it. But during compilation it gives me an error "NOt all code paths return value. I am not able to find out why public static string Reverse(string s) { try { if (string.IsNullOrEmpty(s)) ...
When using a framework method, the description you get when you highlight over it will list the exception(s) possibly raised. Does it matter if you write the catch handlers in this order? E.g. SqlConnection.Open() can throw: System.InvalidOperationException System.Data.SqlClient.SqlException It is listed in that order. Should my catch...
