"unhandled exception occurred in your application"

[iknowjohnny]

I have a canon camera which has wifi. It has a configuration utility that helps you setup the connection to a wifi access point which i do have. However, whgen i try and run this app called "wifi connection setup" I get the error i mentioned. It also says "object reference not set to an instance of an object". I have reinstalled it, tried downloading it rather then using the disc version, tried repairing net framework, (which i suspected from a post in a google search) virus scans, etc. Sill does this. Any ideas on how to determine what is happening?

Try booting to Safe Mode with Networking (in case you want to get on internet while testing. Safe Mode will also work). See if the utility works there

If it does work in Safe Mode, try a Clean Start to see if something is interfering

http://www.sevenforums.com/tutorial...ation-conflicts-performing-clean-startup.html

You can also see if it works in another User Account

http://www.sevenforums.com/tutorials/181024-user-account-create.html

Or the built in hidden Admin account (disable this account again after testing)

http://www.sevenforums.com/tutorials/507-built-administrator-account-enable-disable.html

If this is a one time setup thing, then if any of these methods work, you will be set up, even if you don't definitively determine the cause

Those errors are indeed often associated with .NET, but it is not 100% so.

Thanks. I tried safe mode and still get that error. I take it this means .NET framework is NOT to blame? And what exactly does it tell me of importance? I realize a lot of things are not loaded in safe mode so those are all no longer suspect, tho i don't know what is or isn't loaded or what to look for now.

 

[A Guy]

I do not believe .NET loads in safe mode? Since the issue is the same in Safe Mode, it's almost sure no 3rd party app is the issue. But Windows still loads the minimum services and drivers. Did you try a different user, or the admin account? It would tell you if it was something about your user. A Guy

 

[iknowjohnny]

I tried but nothing from my account was there including the app i'm having issues with. Plus i have a app that scrambles text so my passwords and user names cannot be hack, and when i turned it off it wouldn't go off so i couldn't even type to get to the app in one of my email accounts. Everything i tried to do got stopped in it's tracks by some issue due to being logged in as that admin account. So i just gave up on that.

 

[A Guy]

Ahhh, a shame as that would tell us if it was just that one user. Can you post a screenshot of the exact error, and it's detail tab?

Also see the instructions for checking the event viewer for a more detailed error message marked as Answer here:

Net framework error unhandled exception has occurred in your - Microsoft Community

You might find if this is a known issue with this application on the Canon Camera forum as well

I saw that post and tried the event viewer a while back with to no avail, tho i can't remember what exactly happned. I've tried so many things i don't recall a lot of what happened but i did try that. Heres the text from the error...

Unhandled exception has occurred in your application. If you click continue, the application will ignore this error and attempt to continue. If you click quit the application will close immediately.

See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

I'm going to see if anyone else has any ideas...

I tried but nothing from my account was there including the app i'm having issues with. Plus i have a app that scrambles text so my passwords and user names cannot be hack, and when i turned it off it wouldn't go off so i couldn't even type to get to the app in one of my email accounts. Everything i tried to do got stopped in it's tracks by some issue due to being logged in as that admin account. So i just gave up on that.

This sounds so suspect I would expect it to give chronic problems. Can you uninstall it to see if it is blocking connection?

Is the error reporting on the camera when you try to connect to router, or on the PC itself?

Can you try to connect the camera directly to the router as I did for my Dad's and then it should show up in Devices and Printers without enabling software?

Do you have a 3rd party firewall? What does the Canon Manual for your model say about this?

This sounds so suspect I would expect it to give chronic problems. Can you uninstall it to see if it is blocking connection? It's not at all problematic, it only happened when i logged in as Guy told me to with the hidden admin account.

It has nothing to do with the camera. It's an app that gives the error and won't start and doesn't need the camera to use it, just the wifi device.

Can you try to connect the camera directly to the router as I did for my Dad's and then it should show up in Devices and Printers without enabling software? No, the router is not available to me in my current living situation. I share the bill with the person i sublet from

Do you have a 3rd party firewall? What does the Canon Manual for your model say about this? No firewall

...

 

[gregrocker]

So the access point is not a router? What is it?

The problem is likely a conflict with the app that you're using, which may be unnecessary because those camera's can connect directly. Have you tried that? Mine showed how in the Canon Manual.

Any app you're using to scramble text that won't allow you to function as hidden Admin is not something I'd want to have, and certainly is something I'd uninstall or disable to troubleshoot the problems you're having if you must use a connection app. I never use any connection app because Win7 and most routers or access points allow direct wifi connections from cameras and other devices.

 

[iknowjohnny]

Yes, i disabled it along with any other app. In fact i ended every process in task manager that could be ended at one point and it still did this. The USB access point device has it's driver installed because windows couldn't find one for it. So i used the one on the CD that came with it and even downloaded it in case the version was newer/different but it wasn't. I tried everything imaginable to connect and the PC can see the camera in the access point device's app but the camera never finds the PC.

 

[gregrocker]

1. Try connecting camera directly to access point as shown in Manual, not using any app or the PC.

2. With camera wireless switched on, try Add Device in Win7 Devices and Printers.

 

[iknowjohnny]

I tried that already. No go. It never finds it.
