Instead of using System.IOs file streams, stream writers, etc., Visual Basic 2005 allows us to modify files using the My namespace. I like to use the My namespace for text writing because its easy! Lets get started.


If you just want to create your text file perform this:

My.Computer.FileSystem.WriteAllText(FilePath, "", False)

We are actually writing "" (blank) to the text file. By default, the file will be created if it doesn't exist.

If you want to write text to the newly made file just do this:

My.Computer.FileSystem.WriteAllText(FilePath, "text to be written", False)

If you want to append an existing file, just change False to true.

If you want to delete the file we made just run this:

My.Computer.FileSystem.DeleteFile(FilePath)

I hope that this tutorial will help you better under stand the FileSystem class in the My namespace and show you how the FileSystem class can easily replace the System.IOs file streams and stream writers/readers.

NICE.

Based on your code, I'm using the following to read in the contents of a text file after making sure it exists.

Quote

If File.Exists(filepath) Then
            Label3.Text = My.Computer.FileSystem.ReadAllText(filepath)
        End If

How do I read in one line at a time from the file so I can store them in subscripted variables? Each of the lines in the file have a vbNewLine added on.

Example when I append the file...

My.Computer.FileSystem.WriteAllText(filepath, Form1.heroname & vbNewLine, True)

Just read the files contents into a string. Then, split the string by vbNewLine.

Dim fileText as string = My.Computer.FileSystem.ReadAllText("Path")
Dim arr() as String = fileText.Split(vbNewLine)

You then can manipulate the array to do what you would like.

Would this work with a non-text file, say a Configuration File? How much difference would there be in the coding?
