Masked TextBox

[Meelis Lilbok]

Hi

Is it possible set mask in masked textbox for selected chars only?
For example numbers 0-9 and letters A-F (hex. chars only)

not sure if you can do it as part of the mask itself, but obviously you
could do something like the follwing in the TextChanged event...

Private Sub CheckIfHex(ByVa l sender As System.Object, ByVal e As
System.EventArg s) Handles MaskedTextBox1. TextChanged
Dim allowedchars As String = "1234567890abcd efABCDEF"
Dim i As Integer = 0
For i = 0 To MaskedTextBox1. Text.Length - 1
If Not allowedchars.In dexOf(MaskedTex tBox1.Text.Subs tring(i, 1))

0 Then

MsgBox("Not a valid hex character")
End If
Next
End Sub

I would prefer using the keypress or keydown event for the textbox and
stop any non-hex digits there. Then you would just have to stop the
user from pasting in the inappropriate characters (you could override
WndProc and kill the WM_PASTE message).

Let me know if you need some sample code.

Thanks,

i did so

Private Sub txtKey_KeyDown( ByVal sender As Object, ByVal e As
System.Windows. Forms.KeyEventA rgs) Handles txtKey.KeyDown
e.SuppressKeyPr ess = Not ((e.KeyCode >= Windows.Forms.K eys.A And
e.KeyCode <= Windows.Forms.K eys.F) _
Or (e.KeyCode >= Windows.Forms.K eys.NumPad0 And e.KeyCode <=
Windows.Forms.K eys.NumPad9) _
Or (e.KeyCode >= Windows.Forms.K eys.D0 And e.KeyCode <=
Windows.Forms.K eys.D9) _
Or e.KeyCode = Windows.Forms.K eys.Left Or e.KeyCode =
Windows.Forms.K eys.Right)
End Sub

and shortcuts of course disabled
