Streamwriter Problem

[Jay1b]

I copied the majority of the following text from the msdn library,

but I have those annoying lilttle blue lines under the imports section and the file in the file.append bit.

 

Imports System

Imports System.IO

 

Public Sub ReadBuffer2()

 

Dim path As String = "c:\MyTest.txt"

Dim sw As StreamWriter

 

sw = File.AppendText(path)

sw.WriteLine("This")

sw.WriteLine("is Extra")

sw.WriteLine("Text")

sw.Flush()

sw.Close()

 

End Sub

 

I can get arid of the imports section by putting system.io before streamwriter - but i still get the line under the FILE in file.append

 

Thanks.

I would just like to say that i have done this another way, but i just want to know why this isnt working. As i cant see why it shouldnt.

 

The way i have done it is:

 

Public Sub ReadBuffer2()

 

Dim sw As New System.IO.StreamWriter("C:\test.txt", True)

 

sw.WriteLine("This")

sw.WriteLine("is Extra")

sw.WriteLine("Text")

sw.Flush()

sw.Close()

 

End Sub

 

But could someone please tell me why the first script didnt work please?

the easiest way would be like this....

       Dim path As String = "c:\MyTest.txt"

       Dim sWriter As New StreamWriter(New FileStream(path, FileMode.OpenOrCreate))
       With sWriter
           .WriteLine("test")
           .WriteLine("123")
           .WriteLine("456")
       End With
       sWriter.Close()

 

although when i tried your first method....

       Dim path As String = "c:\MyTest.txt"
       Dim sw As StreamWriter

       sw = File.AppendText(path)
       sw.WriteLine("This")
       sw.WriteLine("is Extra")
       sw.WriteLine("Text")
       sw.Flush()
       sw.Close()

that also worked and that could also be shortned slightly to still work , like this...

       Dim path As String = "c:\MyTest.txt"
       Dim sw As StreamWriter = File.AppendText(path)
       With sw
           .WriteLine("This")
           .WriteLine("is Extra")
           .WriteLine("Text")
           .Flush()
       End With
       sw.Close()

hmmm......

 

When i tried it, it found a problem with the FILE bit, namely File itself. Maybe the bit infront of the FILE hadnt been imported correctly. I know streamwriter is system.io, what would FILE's be?

 

Thank you.

File class is in the System.IO namespace too. What are the exact errors you are getting?

[Jay1b]

I was just getting the blue line underneath it, i have found another way of doing it, i just wanted to know why it didnt work.

 

It was because the system.io was being called infront of the FILE.

 

When you use:

IMPORTS System

IMPORTS System.IO

 

Can these go anywhere, or just in certain places?

[PlausiblyDamp]

The imports need to go above the class declaration - I just put them at the top of the file below Option Explicit On and Option Strict On

Excellent Thank You!
