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?
How do you delete a file even if it's in use?

I have a WPF form with an Image control and an Open button (among other things), and when you select a zip file (by using the Open button), it opens the zip file and extracts it to a special directory, and then takes the image from that directory (that used to be in the zip file, for the zip file contains six files, one of them being the image "bkgd.png"). I load that into the Image control on the WPF form and everything works just fine, until I decide to open a new zip file and do the same thing.When it opens a new zip file, it starts by changing the Image control's source to Nothing (in an attempt to remove my program's association with that file), and then it should be deleting all of the files in that special directory, and then extracts a new zip file and continues the process explained above.However, when I change the source to Nothing, the Image control still displays the image, and then when I try to delete the image, it states that it cannot delete the image because it is being used by another process (although the only program it was ever open in was my program, and it should not be open in my program anymore).I have tried pretty much anything I could think of, and I still can't find a way to get around this. If I can't find a solution, I cannot continue with my work.[code]

I am trying to figure out where to place a code that would cause an application to always delete a database file ONLY when being installed. However, it should not delete this file after installation I.e. when being used. I know you can use: If File.exists() Then File.delete(). But where do you place this code sothat it does not Delele the file when being run? I have tried this but it copies a new file everytime I run the application and data is lost.
