#17309 |

My company use xceed.grid to show data, and use generate report function to preview its report. But when printer disconnected in local machine, we encounter a overflow function as well as preview part can’t be seen. I don’t know how to prevent this error message to show to client instead a friendly message. Help me please.

The best way to solve the problem would be to used a try-catch exception handling statement, since an unhandled exception will always give unwanted results.  Assuming you are programming in C#,

In the

try {…}

you would put the corresponding segment of code and in the  

catch {..}

section, you would tell your user that it’s not possible to print the report right now, using a message box or something similar.  More details about the try-catch statement can be obtained from this Microsoft page: http://msdn.microsoft.com/en-us/library/0yd65esw(VS.71).aspx

An interesting article about software exceptions handling covering a few languages can also be found here:
