File open in other program, can't be saved

VB

Hi all,

Basically it's a IU where user can open a text file through notepad.
The user is then suppose to:
*Change some values in the text file
*save the document though notepad
*get back to the UI.

The problem is that the document can't be saved because "file is open in other program and can't be saved." (translated error massage)

Is there any way of getting around this problem.
I have snipped out the code below.

Dim ProcessProperties As New ProcessStartInfo
Dim myProcess As Process
reader.close()
ProcessProperties.FileName = "notepad.exe"
ProcessProperties.Arguments = lblCurrentFilePath
ProcessProperties.WindowStyle = ProcessWindowStyle.Normal
myProcess = Process.Start(ProcessProperties)
myProcess.WaitForExit()
myProcess.Kill()
OpenFileDialog1_FileOk(bFileEditM, AcceptButton)

Best regards

What I have tried:

not much, only the code above. Don't know any solution.
