On Error Resume Next Vbscript Example
12 down vote favorite In Visual Basic I wrote just On Error Resume Next in the head of my program and errors were suppressed in the entire project. Here in C# I miss this feature very much. The usual try-catch handling for every single procedure is not only very time-intensive, it brings undesired effects. If an error is encountered, even if handled, the code doesn't continue from the point it occurred. With On on error resume next excel vba Error Resume Next, the code continued from the point of error, skipping just the function call that caused the error. I am not deeply involved with C# yet, but maybe there exists in C# a better error handling than the primitive try-catch. I also would like to have the module or function name where the error occured as well as the the line number in my error message. The Exception class doesn't provide that features as far I know. Any ideas (managed, of course, without involving any process classes on my own application)? How do you handle the errors in bigger projects? I hope I do not have to add a try-catch to each method. Somehow C# throws many errors - that seems to be typical of the language. My Solution which I found to re-solve several of my problems: public partial class Form1 : Form { public Form1() { InitializeComponent(); } [STAThread] static void Main() { Application.ThreadException += new System.Threading.ThreadExceptionEventHandler(Application_ThreadException); //setup global error handler Application.Run(new Form1()); } private static void Application_ThreadException(object sender, System.Threading.ThreadExceptionEventArgs e) { MessageBox.Show("Unhandled exception: " + e.Exception.ToString()); //get all error information with line and procedure call Environment.Exit(e.Exception.GetHashCode()); //return the error number to the system and exit the application } private void button1_Click(object sender, EventArgs e) { string s = ""; s.Substring(1, 5); //Produ

Ideally, would like to catch any exceptions http://stackoverflow.com/questions/11596045/i-miss-visual-basics-on-error-resume-next-in-c-how-should-i-be-handing-erro and log them to log.txt file and examined later instead of having exceptions abruptly exiting code. Visual Basic: For i = 1 to 100 On Error Resume Next ReturnedOpcVal[i] = OPC.ReadTag(“Server.Path.Tag” & "TagName_" & Cstr(i)) Next i C++, I’m thinking this: Try { // Try looping through code here For (i = 1; i <= 100; i++) { // Read OPC tags code here } } Catch(…) { // log error to file code } c++ vba visual-c++ vb6 share|improve this question edited Dec 17 '13 at http://stackoverflow.com/questions/20639913/visual-basics-on-error-resume-next-for-c 16:47 Steven Doggart 31.8k42466 asked Dec 17 '13 at 16:46 BgreenDSI 1111311 1 Short answer is yes, exactly that: exceptions. –Adriano Repetti Dec 17 '13 at 16:49 @Adriano - no you are incorrect, if an error is generated in the C++ code the loop will not continue to run, in the VB code it will. –Matt Wilko Dec 17 '13 at 16:57 @MattWilko I didn't say his code is correct or how he has to change it (that's why it's a comment instead of an answer), just that he has to use exceptions (with link to tutorial, letting him to see how they works and how to use them). –Adriano Repetti Dec 17 '13 at 17:00 @MattWilko Thanks –BgreenDSI Dec 17 '13 at 17:03 @Adriano Thanks –BgreenDSI Dec 17 '13 at 17:03 add a comment| 2 Answers 2 active oldest votes up vote 4 down vote accepted This would be the equivalent of the VB code: for (i = 1; i <= 100; i++) { try { // Read OPC tags code here catch(…) { } } } but you may want to wrap another try catch block round the whole lot as well. share|improve this answer edited Dec 17 '13 at 16:52 Adriano Repetti 38.3k965116 answered Dec 17 '13 at 16:50 Matt Wilko 19.7k848107 Thanks, wrapping another around whole lot is a good idea. –BgreenDSI Dec 17 '13 at 17:01 add a comment| up vote 5 down vote There's nothing like that.

On Error is generally considered to be a huge wart of VB, so why would you want to avoid the superior equivalent in C# and try to emulate it? 0 Discussion Starter jireh 3 8 Years Ago ok... you can use a try catch but on error resume what if i have 100 lines of code, you mean to say you have to try catch it in 100 times? or arrrgggghhhh! please see below sample. private int Calculate(int x, int y) { x=x+y; y=y-x; Calculate=x+y; return Calculate } My problem is we don't know what line will the error occur. suppose the error will be in x=x+y; so it will resume in y=y-x; or the error will be in y=y-x; and again it must resume in Calculate=x+y; and please don't ask me why it must resume...Just help me to this issue please... that it must resume to next statement if there's an error... regards, Jireh × Isn't it about time forums rewarded their contributors?
