อยากสอบถามว่าข้อมูลที่เรา get มาจาก Database หรือ TextBox จะรู้ได้ยังไงว่าเป็นภาษาอะไร ไทย หรือ อังกฤษ

    Sub Main()
        'Dim r As String
        Dim a As String
        Dim m As Integer = 20
        Dim n As Integer = 5
        Dim myString() As String
        Dim i As Integer
        a = Me.TextBox1.Text
        'Me.lblText.Text = ""
        Dim strName As String = me.TextBox1.Text
        Dim strRegularPattern As String = "[ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz]"
        Dim strThaiPettern As String = "[กขฃคฅฆงจฉชซฌญฎฏฐฑฒณดตถทธนบปผฝพฟภมยรลวศษสหฬอฮ]"
        Dim strTatalPettern As String = "[ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyzกขฃคฅฆงจฉชซฌญฎฏฐฑฒณดตถทธนบปผฝพฟภมยรลวศษสหฬอฮ]"
        If Regex.IsMatch(strName, strRegularPattern) Then
            myString = a.Split(" ")
            For i = 0 To UBound(myString) Step 1
                Me.lblText.Text = Me.lblText.Text & " " & myString(i)
                If i = m Then
                    Me.lblText.Text += "<br>"
                    m = m + 20
                End If
            Next
        ElseIf Regex.IsMatch(strName, strThaiPettern) or Regex.IsMatch(strName, strTatalPettern)  Then
            myString = a.Split(" ")
            For i = 0 To UBound(myString) Step 1
                Me.lblText.Text = Me.lblText.Text & " " & myString(i)
                If i = n Then
                    Me.lblText.Text += "<br>"
                    n = n + 20
                End If
            Next
        End If

    End Sub
