Question

I have this code:

      Dim FILE_NAME As String = "C:\filename.txt"

            Dim objWriter As New System.IO.StreamWriter(FILE_NAME)

            objWriter.Write(TextBox1.Text)
            objWriter.Close()

but I want to make something like this (note the objWriter.Write(TextBox.Text) in the text belowe):

      Dim FILE_NAME As String = "C:\filename.txt"

            Dim objWriter As New System.IO.StreamWriter(FILE_NAME)

            objWriter.Write("Lorem ipsum dolor sit amet, consectetur adipiscing objWriter.Write(TextBox1.Text). 
                             Duis dignissim, lacus vel tincidunt pellentesque, lacus ipsum venenatis libero, 
                             faucibus iaculis lectus diam id libero. Mauris interdum augue id lacus
                             commodo consequat. objWriter.Write(TextBox2.Text) et ligula sed sapien")

            objWriter.Close()

Update:

Actual output:

Lorem ipsum dolor sit amet, consectetur adipiscing objWriter.Write(TextBox1.Text). Duis dignissim, lacus vel tincidunt pellentesque, lacus ipsum venenatis libero, commodo consequat. TEST et ligula sed sapien

Wanted output (I would to go at head):

Lorem ipsum dolor sit amet, 
consectetur adipiscing objWriter.
Write(TextBox1.Text). 
Duis dignissim, lacus 
vel tincidunt pellentesque,
 lacus ipsum venenatis libero, 
commodo consequat. TEST et ligula sed sapien

Answer 1

The simplest (but not necessarily ideal) way to do this, in your current code:

' UPDATED: Use Environment.NewLine to insert new line breaks:

Dim output As String = "" & _
        "Lorem ipsum dolor sit amet, consectetur adipiscing " & _
        Environment.NewLine & _
        TextBox1.Text & " " & _
        Environment.NewLine & _
        "Duis dignissim, lacus vel tincidunt pellentesque, lacus ipsum venenatis libero, " & _
        "commodo consequat. " & _
        Environment.NewLine & _
        TextBox2.Text + " " & _
        Environment.NewLine & _
        "et ligula sed sapien"

'You are trying to write to root of C here. May require elevated privileges.
' Try writing to your user directory, or documents folder. 
Dim FILE_NAME As String = "C:\filename.txt"
Dim objWriter As New System.IO.StreamWriter(FILE_NAME)
objWriter.Write(output)
objWriter.Close()

Note that you may be running into permission problems attempting to write a file directly to the root of C drive. I had similar issues with this code until I changed the directory path to my home folder, unless I run VS as Administrator (which your users are unlikely to be doing).

That said, you may actually be asking how to insert the contents of the textbox in read from the streamwriter, in which case you will have to come up with some way to tind the proper insertion point. But this is how you accomplish specifically what you describe in your code above.

UPDATE:

You may want to use something like THIS to specify your output directory and file name. Or, of course, use a SaveFileDialog, and allow the user to specify.

Dim path As String = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments)
Dim FILE_NAME As String = Path & "\MyNextNewFile.txt"
