Okay...not sure there will be a solution to this other than something weird happened with the files for this app, but here goes.
After installing .Net 2005, I went and changed different things to set the environment up like I like, one of which is to turn option strict ON. I was recently working on an app and everything seemed fine. Well, I stopped for a little to work on a different app and I copied some of the code over from the previous app because I was doing a lot of similar things...just different variable names and such.
Anyway, some of the code that worked fine in the first app, gave me option strict errors in my new app. I checked to make sure that option strict was on and it was and still is. So, I wanted to try turning it off and then back on, but I can't. I can go to Tools>options and change it to off, but the errors remain. I also tried going into Application.Designer and tried to change it there, but that doesn't work either.
Maybe when a new app is started, if option strict is ON, then it is on for the life of the app? I can get around it, but I am having to do things that I didn't have to do in the previous app, just to get what is essentially the same code to work.
