Simple Replace Text In TextBox - Help Needed

Here is what i have so far

Code:

---

  Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim r As New Random
        Label1.Text = r.Next(1, 5)



        If Label1.Text = "1" Then
            RichTextBox1.Text = Replace(RichTextBox1.Text, TextBox1.Text, "resgg")
        ElseIf Label1.Text = "2" Then
            RichTextBox1.Text = Replace(RichTextBox1.Text, TextBox1.Text, "thnks")
        ElseIf Label1.Text = "3" Then
            RichTextBox1.Text = Replace(RichTextBox1.Text, TextBox1.Text, "please")
        ElseIf Label1.Text = "4" Then
            RichTextBox1.Text = Replace(RichTextBox1.Text, TextBox1.Text, "overs")
        ElseIf Label1.Text = "5" Then
            RichTextBox1.Text = Replace(RichTextBox1.Text, TextBox1.Text, "tester")

        End If

At the moment i have to enter text in Textbox1 that i want to replace, and then when i click the button it will replace it with a random entry from the list.


That's great but ideally i want a solution where i can select text in the RichTextBox1 between markers like * or / and replace the chosen text on every button click, not just once.

At the moment it replaces text in the RichTextBox1 only once. I need it to do it every time i click the button.


It is for a content rewriter.

Any help greatly appreciated. :)

Firstly, your random would never return 5. You'll have to call r.Next(Min, Max + 1) for it to work properly.

Secondly, you might want to use an array to hold the strings, and a variable to hold the number, not a label. Like so:

Code:

---

Dim R As New System.Random, I As Int32 = R.Next(0, 4 + 1)
        Dim Strings() As String = {"resgg", "thnks", "please", "overs", "tester"}
        Me.RichTextBox1.Text = Replace(Me.RichTextBox1.Text, Me.TextBox1.Text, Strings(I))

Thirdly.. I'm not quite sure what you're trying to do. What do you mean it does it only once?

ideally i want to be able to select a piece of text in brackets in the richtextbox, like this..

{this is an} example of text here

and have the text in brackets change to to a random value in the list, every time i click the button.


so on button click one...

"please example of text here"


so on button click two

"thnks example of text here"

What kind of application is this? :confused:

Changing existing text into something randem doesn't sound healthy.
