Question

does someone have an example code for how to prevent .exe files to be started?

Something like this might work:

For Each OSKInstance As Process In Process.GetProcessesByName("OSK").ToArray
OSKInstance.Kill()
Next

But that might be resource intense as a while loop is running all the time. Is there a smarter way to lock an .exe?

Answer 1

Found the code:

Dim myFileStream As System.IO.FileStream
Dim sFileName As String = Application.StartupPath & "\test.exe"
'block
myFileStream = New System.IO.FileStream(sFileName, FileMode.Open, FileAccess.Read,    FileShare.None)
'unblock
myFileStream.Close()
