Nice exceptions.like this. My code looks like : try { blah blah blah } catch (Exception) { MyOwnException myoe = new MyOwnException ("Error on receiving data"); throw myoe; } And what I get when an error happens is a window telling me : "Application1 has encountered a problem and needs to close. Send Error Report Don't Send" Then after clicking either "Send" or "Not Send", the windows closes and the program vanishes. As far as I remember I'm catching the exception and the program should be keep working after that. Where's my fault ? craigkeniss***@hotmail.com wrote:

In other words, it appears that the MyOwnException is not beign caught. -- Tom Shelton <craigkeniss***@hotmail.com> wrote:

Thus something else must catch it, or you'll get the blow-up screen. You should should google try catch finally brad abrams and you can read where "You should be writing many many more try/finally blocks and not so many try/catch/finally blocks. <craigkeniss***@hotmail.com> wrote in message Show quoteHide quote news:1158866316.744452.190120@e3g2000cwe.googlegroups.com... > I'm new to VS2005, I used VS2003 a bit, and I remember it didn't act > like this. > > My code looks like : > > try > { > blah > blah > blah > } > catch (Exception) > { > MyOwnException myoe = new MyOwnException ("Error on receiving data"); > throw myoe; > } > > And what I get when an error happens is a window telling me : > "Application1 has encountered a problem and needs to close. > Send Error Report Don't Send" > > Then after clicking either "Send" or "Not Send", the windows closes and > the program vanishes. > > As far as I remember I'm catching the exception and the program should > be keep working after that. > > Where's my fault ? > My complain is not why it is thrown, but why the application closes...
and I figured out why, but yet need to know how to workaround it. The problem was this: it was on an thread. If I run the same code without threading, the error is shown in a nicer box with "Stop" and "Continue" buttons. Then the application doesn't close on the error. Now, the question, is it normal with a threaded application that a thrown exception put the application down ? sloan wrote: Show quoteHide quote > I usually create a class, called > > EntryPoint.cs > > > [STAThread] > static void Main(string[] args) > { > try > { > > Application.Run(new Form1()); //Whatever your startup form is > > } > > } > catch (Exception ex) > { > //Notify User > MessageBox.Show( "A (uncaught) exception has occured.
