Writing a file to disk

[Pugman812]

I was wondering how you would write a file to disk. In 6.0 you used the open command. I was just wanted to know the process of writing to disk.

What kind of file were you looking at writing? There are a few methods available. Text files are the easiest and can be done using the FileStream classes:

    Dim sr As StreamWriter = File.CreateText(FILE\_NAME)
    sr.WriteLine("This is my file.")
    sr.Close()

Binary files are a little more complicated but are still be based on FileStream classes:

    Dim fs As New FileStream(FILE\_NAME, FileMode.CreateNew)
    ' Create the writer for data.
    Dim w As New BinaryWriter(fs)

' Write data.
Dim i As Integer
For i = 0 To 10
w.Write(CInt(i))
Next i
 
w.Close()
fs.Close()
 
' Create the reader for data.
fs = New FileStream(FILE_NAME, FileMode.Open, FileAccess.Read)
Dim r As New BinaryReader(fs)
' Read data from Test.data.
For i = 0 To 10
Console.WriteLine(r.ReadInt32())
Next i
w.Close()
