    .NET Framework 2
    Component Factory Krypton Tools

    Test PC :-
    .Net Framework 2

      Somewhere you are using an object that has not been defined (it is still null)
      Try running in debug to get a better idea of where it is erroring.

      since there was no line number listed in the stack trace I am guessing it is happening in the constructor.
      Either yours or the ComponentFactor y.Krypton.Toolk it.KryptonForm class's constructor.


      Although if your timer_tick function executes before this line:
      InitializeCompo nent();
      it might cause trouble too

          Code:
          System.NullReferenceException: Object reference not set to an instance of an object.
   at Backup.frmMain.ShowError(String title, String body)
   at Backup.frmMain.Form1_Load(Object sender, EventArgs e)
   at System.Windows.Forms.Form.OnLoad(EventArgs e)
   at ComponentFactory.Krypton.Toolkit.KryptonForm.OnLoad(EventArgs e)
   at System.Windows.Forms.Form.OnCreateControl()
   at System.Windows.Forms.Control.CreateControl(Boolean fIgnoreVisible)
   at System.Windows.Forms.Control.CreateControl()
          A tip on reading these. They are in reverse chronological order. Meaning the line at the bottom happened first, the line at the top was most recent and right before the crash.

          So you got as far as Backup.frmMain. Form1_Load, then crashed at .ShowError(stri ng title, string body);

          I'd start with putting a breakpoint at the first line of your ShowError method and walk through checking to see which variables are null.

              You might also find that a Dictionary<stri ng, string> to be more friendly than a String[ , ]

                  Thanks for the help, It definitely is that ShowError procedure, so I have to work out why its doing it (errors on the H drive check). If i log into the network and I have a home drive, (ie: doesnt call the ShowError message), I receive the following.

                  See Image:

                  What would be causing that? This is only re-producable on the test box. The Development box doesnt do this, so im assuming something is installed, or something's on here that's not on that.

                          What would be causing that? This is only re-producable on the test box. The Development box doesnt do this, so im assuming something is installed, or something's on here that's not on that.

                          Notice how lines 265 and 459 aren't exactly formated the same.

                              Thanks alot for that, that has resolved the null problem.

                              Any tips for that other pesky error? As soon as the application executes, I get that "Backup has encountered a problem and needs to close." I have some feeling that something isnt installed on the other PC because this doesnt happen on my development PC. They both have .NET Framework 2 installed.

                                  Logging, breakpoints, too many threads

                                  Breakpoints are your friend. Put one early and follow it step-by-step with F-10

                                  Logging... Say it with me... Logging. Have every method write to a text file at the start and end. You can trace how far it got.

                                  Mine tend to start out with environmental information so I can get a feel for the client machine

                                      OH - And I highly recommend putting in some type of Virtual Machine system on your development PC. Its really nice to test on WinXPsp1, WinXPsp2, WinVista... etc. without having to have multiple computers.

                                      Another test for you could be sheer number of files being backed up. Your development machine works fine backing up 50, but what happens for the user when it goes to back up 5,000? Too many threads... in sufficient memory...

                                      Or user rights... Your development machine has god priviledges to the server but your users don't...

                                          That logging stuff you posted up there, you wouldn't happen to be able to share that at all? =P

                                          (the code for that, that is) I love the Removable drive part.. Something im looking for another application im wanting to write.

                                              The Bytes volunteers are not here to write your code for you.
                                              Bytes is very much a "Give me a fish I eat for a day. Teach me to fish I eat for a lifetime" kind of place. Just giving you the code doesn't help you learn near as effectively as good old-fashioned trial and error.
                                              So I will follow my own advice by pointing you at where to read up.
