Hi everyboyd, im trying to make a function which will keep the cursor to its position if non integer value is entered into a textbox. im using the following code:

Public Class Form1
    Private Sub txtNo_KeyUp(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles txtNo.KeyUp
        NumericOnly(txtNo.Text)
    End Sub
    Public Function NumericOnly(ByVal sValue As String) As String
        Dim sAns As String
        Dim sChar As String
        Dim sNewString As String
        Dim lLen As Long
        Dim lCtr As Long
        Dim nc As Integer

        sAns = sValue
        lLen = Len(sValue)
        For lCtr = 1 To lLen
            sChar = Mid(sAns, lCtr, 1)
            If Asc(sChar) > 47 And Asc(sChar) < 58 Then
                sNewString = sNewString & sChar
            End If
        Next
        NumericOnly = sNewString
        txtNo.Text = sNewString
        nc = txtNo.SelectionStart
