    I am new to this forum so sorry if I do something wrong. I have a RichTextBox1 and RichTextBox2 on my form. RichTextBox1 is for the user to enter some text. RichTextBox2 is not visible on form. I am trying to get the code to take the users text and put in RichTextBox2 to be able to save all the text each time the user hits saved button. I am not sure the best way to go about this. My code below saves the text ok the first time the saved button is hit but when the user adds more text and save again, it is adding the new text and the old text again. I just want it to save the new text only along with the old text but not add the old text again.
    
Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click         If RichTextBox1.Text.Length > 0 Then             RichTextBox2.AppendText(RichTextBox1.Text)             If RichTextBox2.Text = RichTextBox1.Text Then                 MessageBox.Show("Text was Saved")             End If          Else             'do nothing         End If     End Sub


    Is This A Good Question/Topic? 0

    Hello donna2002,
    You will need to save the text from textbox2 in a string variable and clear the text from textbox2 before saving the text from textbox1. Thats what it sounds like from the way your explaining it. Try this
    
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click         If RichTextBox1.Text.Length > 0 Then             Dim txt As String = RichTextBox2.Text             RichTextBox2.Clear()             RichTextBox2.Text = RichTextBox1.Text             If RichTextBox2.Text = RichTextBox1.Text Then                 MessageBox.Show("Text was Saved")             End If         End If     End Sub

    Thank you IronRazer for the reply. Yes, that does work but maybe I am not explaining too well. That code does work until the user deletes something or clears his text to start over. I need the RichTextBox2 to always keep the text when the save button is clicked even if the user clears his or does whatever it still needs to keep the old text and add only the new text to RichTextBox2. I am probably not explaining it well. In other words I need both RTB to compare to each other and if there is new text added to RTB1 then add only that text to RTB2 along with what is already in RTB2. I have tried different ways but keep getting RTB2 with too much text adding the old and new text together and having duplicates of the same text when the user only entered it once. I hope that clears it up some. I am not good explaining myself.
