[RESOLVED] My app's stopped working.

[Poppa Mintin]

Hi,
I have an app which has been running perfectly well for several years. Today, for no apparent reason it will not run. I've loaded it into Visual Studio 2019 vb.NET to try to find why it's stopped, but when I click Start, it doesn't run and the Errors dialog reports 0 Errors (entire solution) both before and after clicking start.

Where do I go from here ?

I tried cleaning and rebuilding which seems to've made no difference.

So when you try to run it from within visual studio does anything happen?

Did it even start to run, then exit? Are there any messages in the output window? What happens if you try and step into the application, rather than just running it?

I’ve had similar problems where settings files have become corrupted. Do you use My.Settings in your app?

Thanks for your help guys, it turns out I'd backed-up the app elsewhere so it's all sorted out and working again.

I'll mark it as resolved, but it isn't really !

If you mean a backup of the compiled app then it sounds like you have a very short term fix, just because it looks like the code itself no longer works.

If you mean a backup of the code, then this is why you should be using some form of version control, that would enable you to see what had changed and possibly caused the failure.

Either way I would still try the various suggestions in this thread to see if you can figure out the underlying issues.

Cheers PD, This app has been working propperly for several years, I guess I must've caused some damage when I was working with some experimental stuff last week, I've already ditched that stuff now. Thanks for your concern.

I'm switching to a new machine soon so I may have some trouble then, if it doesn't like Windows 11. (I don't like Win.11 either, but thee's not much else out there, I expect I'll try to get a Win.10 machine))

Do as the man says, and start using version control! Get a github account, move your code up there, closed or open. Make single functional changes and synch each change to github. Then you will be able to back out single changes and your code will be safe forever from your depredations.
