Bug

I've just had an unhandled exception (Object reference not set to an instance of an object).

I viewed a scan log that had no results, clicked 'Finish and Close', and the stack threw:

System.NullReferenceException: Object reference not set to an instance of an object.
at System.Windows.Forms.ToolStripProgressBar.set_Valu e(Int32 value)
at EduSweep.ResultsViewer.backgroundWorkerPopulate_Pr ogressChanged(Object sender, ProgressChangedEventArgs e) in C:\Users\Paul\Visual Studio 2008\Projects\EduSweep\Script Spy\ResultsViewer.cs:line 535
at System.ComponentModel.BackgroundWorker.OnProgressC hanged(ProgressChangedEventArgs e)
at System.ComponentModel.BackgroundWorker.ProgressRep orter(Object arg)

Oooh, okay. I think that's the first bug I've had reported so far! I'll try to reproduce it here.

Update: I've looked at the code and that line is this method here

Code:

---

        private void backgroundWorkerPopulate_ProgressChanged(object sender, ProgressChangedEventArgs e)
        {
            toolStripProgressBarPopulate.Value = e.ProgressPercentage;
        }

---

Quite why this would be firing on close, I'm not sure. I couldn't reproduce the bug on this system but I can see why it might cause a crash. I'll get to patching it. :)

I got another bug for you, sorry. Happened after I downloaded 2.1 and installed. Occurs whenever i click create new signature, new task, everything really. Here the error details

Code:

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
    <system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.

PS this software is great and saves me a load a time at work, thank you very much

Thanks for reporting it. Can I check a few details?

* Does the main window appear okay?
* What OS are you running?
* Could you try clearing the contents of the Tasks and Signatures directories inside the EduSweep folder and see what happens?

Hi Bizzle, the window appeared but looked like there was a clear bar accross the top of it showing the desktop. The problem has being solved partly as i uninstalled and reinstalled it. But now it seems not matter what signatures I use it only searches jpg's (strange i know).

Im using xp pro sp3 fully patched.

edit: scratch that last problem, cleared the tasks and signatures folders and did a software update, works perfectly again cheers again

Hi again,

On Vista the program uses a glass effect on the titlebar (you can turn it off of course!) but it sounds like it's trying to enable on XP as well which is something I haven't seen before. Even if you go into the settings and enable glass it should stay disabled on XP - perhaps it doesn't?

Let me know if the signature problem occurs again - I'm doing a lot of work to the guts in 2.2 and I can always roll in another fix. :)

These bugs should be fixed in the next patch - 2.1.1. I hope to have that ready in the next couple of weeks. Slow progress of late, I've been tied up with AUP Informant 2. :o
