Validate a textbox

Expand Post »

I want to validate a textbox so that only numeric values can be inserted in to it.
This validation should done while user enters the values.
For example.
Consider following keys had been pressed in a sequence

12345abcd678

only numeric values should appear in the textbox

so value which should be displayed in the textbox is
12345678

Any suggesions????? Please comment

        If Asc(e.KeyChar) >= 48 And Asc(e.KeyChar) <= 57 Then
            e.Handled = False
        Else
            e.Handled = True
        End If
    End Sub
