Thank you for your answers. Of course it is possible to work with the debugger or with try/catch but in fact it does not help me because the error is not shown by the debugger. It is a Windows Error Message and that's the great problem.

Hi! I've written a program in C# which is running stable for hours. Then, at some moment, I get the Windows Error Message "The program xy has encounterd a problem an has to close". What I did was writeing some information at different time stamps to a file. What is interesting: the file is filled with information AFTER the Error Message and the whole program still keeps running, only the output (multimedia things) is not shown anymore. So in my opinion I have a performance problem. My question: Does anybody know how to get to the reason for such a Windows error. Can I catch such a Windows error or somehow suppress it? Is there a possibility to free resources of Windows Form manual? Kind regards

You can attach each field of the datatable with nameofdataset.Tables[0].Rows[i].ItemArray[j] with the indexes i an j changing for the Rows and cells you want to change or read out
