Button Functions

This has 5 buttons (Button1 through Button5) which save, select all, cut, copy and paste.

The save function saves the data in plain text format so it uses .txt for the file extension of the file created by it. Although you can change it to save in rich text format with the appropriate file extension for that.

Public Class Form1

    Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
        Me.Text = "Testing"
        Me.CenterToScreen()
    End Sub

    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        Dim saveFile1 As New SaveFileDialog()
        saveFile1.DefaultExt = "*.txt"
        saveFile1.Filter = "Text Files|*.txt"
        If (saveFile1.ShowDialog() = System.Windows.Forms.DialogResult.OK) _
            And (saveFile1.FileName.Length) > 0 Then
            RichTextBox1.SaveFile(saveFile1.FileName, RichTextBoxStreamType.PlainText)
        End If
    End Sub

    Private Sub Button2_Click(sender As Object, e As EventArgs) Handles Button2.Click
        If RichTextBox1.SelectionLength = 0 Then
            RichTextBox1.Focus()
            RichTextBox1.SelectAll()
        End If
    End Sub

    Private Sub Button3_Click(sender As Object, e As EventArgs) Handles Button3.Click
        If RichTextBox1.SelectedText <> "" Then
            RichTextBox1.Cut()
        End If
    End Sub

    Private Sub Button4_Click(sender As Object, e As EventArgs) Handles Button4.Click
        If RichTextBox1.SelectionLength > 0 Then
            RichTextBox1.Copy()
        End If
    End Sub

    Private Sub Button5_Click(sender As Object, e As EventArgs) Handles Button5.Click
        RichTextBox1.Focus()
        RichTextBox1.SelectionStart = 0
        RichTextBox1.Paste()
    End Sub

End Class
