Hej Jag har ett problem om användaren skriver tecken utan mellanslag, då förstörs designen och sidan blir jätte bred. Jag får följande felmeddelande i Visual Studio: Index and length must refer to a location within the string.
Parameter name: length.

Inget felmeddelande när ordet är kortare än 20 tecken.

Jag kontrollerar texten före den skickas in i databasen//Bo

Protected Sub btnLagg2_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnLagg2.Click
               txtDescription.Text = BreakLongWord(txtDescription.Text.ToString).ToString

End Sub

Private Function BreakLongWord(ByVal [text] As String) As String
        Dim spilter As Char() = " "
        Dim words As String() = [text].Split(spilter)
        Dim strDesc As New System.Text.StringBuilder("")
        Dim word As String
        For Each word In words
            Dim newword As String = ""
            If word.Length > 20 Then

                Dim parts As Integer = word.Length / 20
                Dim remainder As Integer = word.Length Mod 20
                Dim counter As Integer = parts
                If remainder > 0 Then
                    counter += 1

                    If i = counter Then
                        newword = newword + word.Substring(((i - 1) * 20))
                    Else
                        newword = newword + word.Substring((i - 1) * 20, 20) + " "
