Plugin not in Config list

McBainUK · 2005-12-04, 10:20 PM

After adding an extra config setting my plugin now does not show in the config app. It builds fine but the config.exe log reports a good old null object ref at the plugin's constructor

Code:
using System;

using System.Drawing;

using System.Collections;

using System.Xml;

using CommonGBPVRUtilities;

            textBoxDefaultCinemaNumber.Text = ConfigFileUtilities.GetStringConfigSetting(settings, UKCinemaListings.MyPlugInConfigSectionName, "DefaultCinema", "1004181",false);

        }

Please Help :confused:

Run it up in the debugger and see where it stops.

***sub*** · 2005-12-04, 10:26 PM

Did you mean to comment out InitializeComponent();?

McBainUK · 2005-12-04, 10:35 PM

No I didnt lol. Uncommented but still the same error.

How do I setup debuging with an external .exe?

Ive set the 'Start program' in Visual Studio.net project properties to config.exe and setup a breakpoint on settings = document; but it just goes straight through and starts the config app. Am I missing something silly?

Thanks for your quick replies sub Smile

You might need to explicitly set the debug type to 'mixed' as some times it gets confused.

You could also try selecting Debug -> Exceptions from the menu, and from there set 'common language runtime exceptions' to 'break into debugger'

Done the 2nd one, couldnt find an option for the 1st one.

McBainUK · 2005-12-05, 07:02 PM

Ok I've tried lots of things. Reverted to a known, working config form and still does not appear in the the plugin list.

Code:
05/12/2005 19:00:30.984    ERROR    [7]    Error initializing menu plugin: C:\Program Files\devnz\gbpvr\\plugins\UKCinemaListings.dll

05/12/2005 19:00:30.984    ERROR    [7]    Exception has been thrown by the target of an invocation.

05/12/2005 19:00:31.000    ERROR    [7]       at System.RuntimeType.CreateInstanceImpl(Boolean publicOnly)

   at System.Activator.CreateInstance(Type type, Boolean nonPublic)

   at a6.e()

05/12/2005 19:00:31.000    ERROR    [7]    Inner exception: System.NullReferenceException: Object reference not set to an instance of an object.

   at UKCinemaListingsPlugin.UKCinemaListings..ctor()

05/12/2005 19:00:31.000    ERROR    [7]       at UKCinemaListingsPlugin.UKCinemaListings..ctor()

I've tried sub's suggestions but still can't get the debugger to work, it says that I can't see the source code at the breakpoint. :mad:

Funny thing is, if I put this in Activate() the config form appears fine (even with correctly loaded config variables!)

Code:
            System.Xml.XmlDocument document2 = new System.Xml.XmlDocument();

            Logger.Verbose("TESTING : " + document2.ToString()); // Write to debug file

            System.Windows.Forms.Form test = GetConfigFormInstance(document2);

            test.Show();

If it can init and show the form, why can't it do it when called by the config app? Please help. Almost finished this release but I'm going crazy with this config form problem.

***sub*** · 2005-12-05, 07:08 PM

If you want to email it over I'll take look. I can see your problem looking at these snippets of code.

McBainUK · 2005-12-05, 07:20 PM

Sent.

***sub*** · 2005-12-05, 07:35 PM

The PluginHelperFactory.getPluginHelper() call returns null when in config mode. The error occur on line 101 of UKCinemaListings.cs when you run the config app.
