I'm having a bit of a problem getting my application to close properly. Basically I have one main form from which all other forms open. If a user tries to close that main form, I want to bring up a MessageBox asking if they want to exit the application.However, when I try to do that it asks the question twice. It seems that the Application.Exit() is triggering the FormClosing event again for some reason, but I don't know of another way to exit the application. BTW, the main form isn't the startup form so I can't use the option to close when the startup form closes.
View 9 RepliesNow I have a sub to validate a bunch of textboxes and combo boxes.I previously used many IF statements to validate and pop up different messageboxes and Exit Sub in every IF statement.But I heard that too many Exits will decrease the efficiency and they were not recommended to use. Instead, nested IF is better because it will let the process naturally go to the end.Then I found out that if I use nested IF,it will be hard to read, since messageboxes are all separated from conditions.

I was wondering how I could delete a file that is currently in use. Well, basically the app that i'm making is an app that detects what files you download. if it detects a certain app, it trys to delete it so you can't click the 'Run' button with-in IE. But, when I try to delete it, I get the 'File is currently in-use' -exception. How could I do this? So if they download aim6.exe and my app doesn't allow it, it will delete it from the temp files so when they click run, all they get is an error like, 'Not a valid Win32 application' ...or something

I have 2 apps:
Main app
Updater
The Main app checks if it's the right version with a webservice. If it's not, it will start the updater.
The updater will check if the main app is still running. If it is, it kills the process. After that it overwrites all the files in the main app folder with new ones.
The problem is, when the main app is using a file and it's killed by the updater. The file that the main app was using isn't cleared at once, this apparantly takes some time.
So when the updater wants to overwrite the file, the file is still in use. I could keep the updater waiting for a minute after it kills the process but this is of course quite error prone.
Is it possible to ignore the file in use thing and overwrite it anyway?
