• Visual C# Using fields as parameters in a method

  I have a requirement in a project to build a history. No biggie, but there are dozens of bool fields and processing each one is very time consuming. My approach is to add a field name to an arraylist when the property is changed. OnSave() or Dispose() I look into the object and check to see if the field list is empty or not. If not, I process the list looking at each item comparing it to a clone of the original object so that only true change ...Show All

• Visual Basic Exception handling doesn't catch errors

  I seem to be missing a fundamental point regarding exception handling. My understanding is that when an error occurs, it can be caught by Catch without abnormally terminating the program. Mine will always abnormally terminate when an error occurs. An example is below. When the connection fails to open, the application breaks instead of executing the Catch block. Why Try cnSQL.Open() xMainMenu.ShowDialog() Me .Close() cnSQL.Clos ...Show All
