Inserting numbers in front of text in a rich text box.

You could always look through the text for vbcr and vblf (char(13) and char(10)) and then put the number afterwards.

dim intI as integer, intLineCnt as integer, strtemp as string
dim intJ as integer

intLineCnt = 10
if txtRTF.text <> "" then
for intI = 1 to len(txtRTF.text) -1
intJ = inString(txtRTF.text, vbcr & vblf)
if intJ <> 0 then
strtemp = strtemp & mid(txtRTF.text, inti, intj +2) & intLineCnt
intLineCnt = intLineCnt + 10
intI = intJ + 3
else
strtemp = strtemp & mid(txtRTF.text, intI)
exit for
end if
next intI
end if

txtRTF.text = strtemp

May have to tweak the intJ + 2 and 3 etc to make sure it brackets the carraige return and line feed correctly but that should work.

There is a much faster way:

Private Declare Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, lParam As Any) As Long
Private Const EM_GETLINE = &HC4
Private Const EM_GETLINECOUNT = &HBA
Private Const EM_LINEINDEX = &HBB
Private Const EM_LINELENGTH = &HC1

Private Sub Command1_Click()
    Dim lCount As Long
    Dim strBuffer As String
    Dim arrBuffer() As Byte
    Dim lIndex As Long
    Dim lLen As Long
    Dim i As Long

    
    With RichTextBox1
        lCount = SendMessage(.hwnd, EM_GETLINECOUNT, 0, 0)
        For i = 0 To lCount - 1
            lIndex = SendMessage(.hwnd, EM_LINEINDEX, i, 0)
            lLen = SendMessage(.hwnd, EM_LINELENGTH, lIndex, 0)
            ReDim arrBuffer(lLen)
            arrBuffer(0) = lLen And 255
            arrBuffer(1) = lLen And 256
            Call SendMessage(.hwnd, EM_GETLINE, i, arrBuffer(0))
            strBuffer = strBuffer & CStr((i + 1) * 10) & " " & Left$(StrConv(arrBuffer, vbUnicode), lLen) & vbCrLf
        Next
        .Text = strBuffer
    End With
End Sub

Thanks for your prompt replies.
