I am having trouble updating lines in a richtextbox. The rtb.lines.setvalue("text", linenumber) runs, but does not update the control in the form. The code follows...
This apps automatically updates an output screen with changes in the file when the file length changes..
Private Sub LoadFile()
Dim lineCount As Integer = 0
Dim line As String
Dim iLength As Integer
If File.Exists(gFile) Then
Dim fs As New FileStream(gFile, FileMode.Open, FileAccess.Read, FileShare.ReadWrite)
iLength = fs.Length
If iLength <> saveLength Then
Dim sr As StreamReader = New StreamReader(fs)
While sr.Peek >= 0
line = sr.ReadLine
If lineCount < slineCount Then
If line <> rtbOutPut.Lines.GetValue(lineCount) Then
PROBLEM CODE -> rtbOutPut.Lines.SetValue("line", lineCount)
End If
Else
rtbOutPut.AppendText(line & vbNewLine)
End If
lineCount = lineCount + 1
End While
slineCount = lineCount - 1
saveLength = iLength
sr.Close()
End If
fs.Close()
Else
saveLength = -1
End If
End Sub
