How to save a content of a specific textbox to file using VB.net

Question

Good morning everyone, I'm working on my finals project in visual basic and i want to implement a save file option.

Right now the application has 2 textboxes (not richtextbox) which are the input and output of information.

What i want to do is save only the content of the output textbox. I managed to get it to save something to file but when its opened it always turns out to be empty.

the code example of the save file button is below, i have a feeling its not saving the content because it is not specified, yet i have no idea how to specify to only save the content of the one textbox even with the many hours of forum / google searching ive done to try and figure out on my own.

        Dim myStream As Stream
    Dim nsavetxtoutput As New SaveFileDialog()
    '|All files (*.*)|*.*
    nsavetxtoutput.Filter = "txt files (*.txt)|*.text"
    nsavetxtoutput.FilterIndex = 2
    nsavetxtoutput.RestoreDirectory = True

    If nsavetxtoutput.ShowDialog() = DialogResult.OK Then
        myStream = nsavetxtoutput.OpenFile()
        If (myStream IsNot Nothing) Then
            ' Code to write the stream goes here.
            myStream.Close()
        End If
    End If

Any and all insight would be much appreciated!

Thank you guys!

Private Sub NOTEPAD_BUTTON(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BTSave2Notepad.Click
    Dim nsavetxtoutput As New SaveFileDialog()
    nsavetxtoutput.Filter = "txt files (*.txt)|*.text"
    nsavetxtoutput.FilterIndex = 2
    nsavetxtoutput.RestoreDirectory = True

    If nsavetxtoutput.ShowDialog() = DialogResult.OK Then
        IO.File.WriteAllText(nsavetxtoutput.FileName, txtoutput.Text)
    End If
End Sub

Try this:

If nsavetxtoutput.ShowDialog() = DialogResult.OK Then
    IO.File.WriteAllText(nsavetxtoutput.FileName, TextBox2.Text)
End If

Where TextBox2 is your output TextBox.

You can write to a file using File.WriteAllText method. It takes two parameters. The first is the path to the file, which you get from the SaveFileDialog. The second is the value you want to write to the file.
