[RESOLVED] No ABC Chars!

Ok, I used this code to stop letters from being entered into a txtBox, could someone help me to change this so that Nums cannot be entered..... :confused:

VB Code:

Private Sub txtExponent_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) _
        Handles txtExponent.KeyPress, txtInput.KeyPress
        If e.KeyChar Like "[!a-zA-Z]" AndAlso Not e.KeyChar = ControlChars.Back Then
            e.Handled = True
        End If
    End Sub
End Class

VB Code:

Private Sub TextBox1_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles TextBox1.KeyPress
        If Char.IsNumber(e.KeyChar) Or Char.IsControl(e.KeyChar) Then
            e.Handled = False
        Else
            e.Handled = True
        End If
    End Sub

VB Code:

Private Sub TextBox1_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles TextBox1.KeyPress
        If Char.IsLetter(e.KeyChar) Then
            'The character being entered is a letter.
        ElseIf Char.IsDigit(e.KeyChar) Then
            'The character being entered is a decimal digit.
        ElseIf Char.IsControl(e.KeyChar) Then
            'The character being entered is a control character.
        End If
    End Sub

The Char type has some other useful methods you should familiarise yourself with also.

Thank you "Again" people!
