[2008] RichTextBox Replace Programmatically

I have a RTB that loads data from a file like this in the Load event of the Form2

Code:

---

Me.rtb_cerere.LoadFile(Application.StartupPath & "\ceelceur.rtf")

---

After i load this file i want to replace some key words with a specified text but here i'm stuck...

I use this...

Code:

---

    Private Sub Button4_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button4.Click

        Dim PozitieCurenta As Integer = Me.rtb_cerere.SelectionStart
        Dim SelectieCurenta As Integer = Me.rtb_cerere.SelectionLength
        Dim CuvantCheie As String = "{1}"

        Me.rtb_cerere.Select(StartPosition - 1, CuvantCheie.Length)
        Me.rtb_cerere.ScrollToCaret()
        Me.Focus()

        Me.rtb_cerere.Rtf = Replace(Me.rtb_cerere.Rtf, Trim(CuvantCheie), Trim("TEST"))
        Me.rtb_cerere.SelectionStart = PozitieCurenta
        Me.rtb_cerere.SelectionLength = SelectieCurenta
        Me.Focus()

    End Sub

---

How can i replace this {1} with "TEST" ? I have spend 2 days and i'm lost in the space!

Thanks...

Code:

---

        Dim testRTB As New RichTextBox
        testRTB.Text = "1234{1}56789abcdefghi{1}jklmnopqrstuvwxyz"
        Debug.WriteLine(testRTB.Text)
        testRTB.Text = testRTB.Text.Replace("{1}", "Test")
        Debug.WriteLine(testRTB.Text)

---

debug output

1234{1}56789abcdefghi{1}jklmnopqrstuvwxyz
1234Test56789abcdefghiTestjklmnopqrstuvwxyz

Thanks alot!
It's working but i have another problem now...

The RTB text loaded from the file is formated and if i use that code the hole text will not keep his properties.

Any ideea about this ?!

try this:

vb Code:

Private Sub Button4_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button4.Click
    Dim PozitieCurenta As Integer = Me.rtb_cerere.SelectionStart
    Dim SelectieCurenta As Integer = Me.rtb_cerere.SelectionLength
    Dim CuvantCheie As String = "{1}"
 
    Dim startAt As Integer = 0
 
    Do While Me.rtb_cerere.Text.IndexOf(CuvantCheie, startAt) <> -1
         Me.rtb_cerere.SelectionStart = Me.rtb_cerere.Text.IndexOf(CuvantCheie, startAt)
         Me.rtb_cerere.SelectionLength = CuvantCheie.Length
         startAt = Me.rtb_cerere.Text.IndexOf(CuvantCheie, startAt) + CuvantCheie.Length
         Me.rtb_cerere.SelectedText = "New Text"
    Loop
 
    Me.rtb_cerere.SelectionStart = PozitieCurenta
    Me.rtb_cerere.SelectionLength = SelectieCurenta
    Me.Focus()
 
End Sub

what do you mean? if you can post what you tried.

using replace on the rtb.text removes all the text formatting

if all else fails i should, read the destructions, hmm, i mean instructions :)

I have tried to take values from another form (Form1 wich is a MDI Child) and use it into another form (Form2 - that uses the RTB code) but it seems it's not working like in VB6 ?

Code:

---

Me.rtb_cerere.SelectedText = frm_eliberare_cerere_certificat_urbanism.txt_nr_cerere.Text

---

Or what i am doing wrong ?

I don't know if it's good or if it's wrong but i used a Public Shared function!

Anyone can tell me if it's OK with that ?

I have another problem with this code...
I take values from the Form1 by using

Code:

---

Public Shared SHR_SatSolicitant as String

          SHR_SatSolicitant = Me.txt_box1.text

---

The problem is when i use the code (down) to replace the string "{13}" if the Form1 SHR_SatSolicitant is EMPTY is not replacing me with "" (empty).

Code:

---


        Dim STR_SatSolicitant As String = "{13}"


            If frm_eliberare_cerere_certificat_urbanism.SHR_SatSolicitant = "" Then

                Do While Me.rtb_cerere.Text.IndexOf(STR_SatSolicitant, startAt) <> -1
                    Me.rtb_cerere.SelectionStart = Me.rtb_cerere.Text.IndexOf(STR_SatSolicitant, startAt)
                    Me.rtb_cerere.SelectionLength = STR_SatSolicitant.Length
                    startAt = Me.rtb_cerere.Text.IndexOf(STR_SatSolicitant, startAt) + STR_SatSolicitant.Length
                    Me.rtb_cerere.SelectedText = Me.rtb_cerere.SelectedText.Replace(Me.rtb_cerere.SelectedText, "")

                Loop

            Else

                Do While Me.rtb_cerere.Text.IndexOf(STR_SatSolicitant, startAt) <> -1
                    Me.rtb_cerere.SelectionStart = Me.rtb_cerere.Text.IndexOf(STR_SatSolicitant, startAt)
                    Me.rtb_cerere.SelectionLength = STR_SatSolicitant.Length
                    startAt = Me.rtb_cerere.Text.IndexOf(STR_SatSolicitant, startAt) + STR_SatSolicitant.Length
                    Me.rtb_cerere.SelectedText = ", satul " & frm_eliberare_cerere_certificat_urbanism.SHR_SatSolicitant
                Loop

            End If

What shold i do ? Thanks again and i'll wait again your big help!
