Visual Basic Form. How to let users save text file where they want

Question

Private Sub Button7_Click(sender As Object, e As EventArgs) Handles Button7.Click
    Dim CurrentDir As String = Environment.CurrentDirectory
    Dim OutputFile2 As String = IO.Path.Combine(CurrentDir, "input.txt")
    IO.File.WriteAllLines(OutputFile2, Result1.Lines)
End Sub

Right now, I have coding that saves a text file in the current directory. However, I want to have a browse button for users so that they can pick where this text file is saved. How do I proceed this?

I was trying it by my self and I'm having a trouble with using save file dialog. If you can teach me how to use a save file dialog or anyway to write save browse button, I would very appreciate it!

Answer 1

The documentation for the SaveFileDialog object contains an example.

Answer 2

Here is a tutorial on how to implement SaveFileDialog using Toolbox in Visual Studio like you mentioned. The code sample is in C# but it can be easily converted to VB.

Private Sub button1_Click(sender As Object, e As EventArgs)
    ' When user clicks button, show the dialog.
    saveFileDialog1.ShowDialog()
End Sub

Private Sub saveFileDialog1_FileOk(sender As Object, e As CancelEventArgs)
    ' Get file name.
    Dim name As String = saveFileDialog1.FileName
    ' Write to the file name selected.
    ' ... You can write the text from a TextBox instead of a string literal.
    File.WriteAllText(name, "test")
End Sub
