Delete a file with vb.net which is open in another process

Question

I create a .txt file in C++ in the application folder /Common/Send/Test.txt Than I call a VB.net application from the c++ code the Vb.net app read the test.txt content than send it to a Web-Server with POST request, than delete the file.

But its not delete the file, the VB.net app crashing when it need to delete the file.

My.Computer.FileSystem.DeleteFile(".\\Common\Send\Test.txt")

I am using this to delete the file, what can be the problem? The problem is its write another program using this file, thats why it cannot delete, how can I stop my application 1st part? Because I read the file, but than its doesnt close it. I think thats the problem.

Answer 1

I would use something like this to delete the file ...

    Try
        System.IO.File.Delete(Environment.GetFolderPath(Environment.SpecialFolder.UserProfile)  + "\Common\Send\Test.txt")
    Catch ex As Exception
        'it may not exist so no worries ...
    End Try

To address the issue of it being open in a different process, here are your options:
