I am transitioning from VB 2 to VB2005 Express, so I’m spending a log of time with textbooks. I have a file containing one single string of text. I want to read the text, update it and re-write it. According to my textbook I can open the file in ReadWrite mode but I can not get it to work. Please consider the following code:
Dim fsStream As FileStream
Dim srReader As StreamReader
Dim swWriter As StreamWriter
Dim strWork As String
fsStream = New FileStream(“C:MyTextFile”, FileMode.Open, FileAccess.ReadWrite)
srReader = New StreamReader(fsStream)
strWork = srReader.ReadLine()
srReader.Close()
swWriter = New StreamWriter(fsStream) <<< This statement abends with the message "Stream was not writeable"
Now I know that I can write this as a separate Read block, close it all down, then write a separate Write block, but i'm trying to learn how FileAccess.ReadWrite works. Can someone please tell me where I'm going wrong?
Thanks,
John Littell
