Simple (or not) text box question

Two things I'm trying to do:

Limit input to digits 0-9 and

on the 2nd number, add a hyphen so the user won't have to type.

My hopefully end result would be 34-123.

Any help would be appreciated.

No Problem

Code:

---

Private Sub Text1_KeyPress(KeyAscii As Integer)
If Not IsNumeric(Chr(KeyAscii)) Then

    KeyAscii = 0

ElseIf Len(Text1.Text) = 2 Then

    Text1.Text = Text1.Text & "-"
    Text1.SelStart = 3
   
End If

End Sub

---

Try this.

Code:

---

Private Sub Text1_KeyPress(KeyAscii As Integer)
    If KeyAscii < 48 Or KeyAscii > 57 Then KeyAscii = 0
    If Len(Text1) = 2 Then Text1.SelText = "-"
End Sub

Thanks guys. It works just like I needed.

Sorry to be a pain but what if I the backspace key to be active? Better yet, is there a chart of KEYASCII codes so I can know what's what?

the backspace key is 8

so enclose everything in the Keypress event in an If Not (KeyAscii = 8) Then ... Endif block.

If you want to get different keyasciis the easiest way is to add another textbox to your form and add this

Code:

---

Private Sub Text2_KeyPress(KeyAscii As Integer)
Text2.Text = KeyAscii
KeyAscii=0
End Sub

---

then run your program , put the curser in the textbox and press the key you want, the correct code will apear in the textbox

James Stanich,
If you are looking for a chart,
MSDN has topics under Character Sets. It lists the charcters along with their charcter codes.

Neat trick. Thanks.

Or even better; use the constant values:

• vbKeyBack
• vbKeyReturn
• vbKeyEscape
• vbKeyA
• vbKeyB
• ...
• vbKeyF1
• vbKeyF2
• ...

And so on...
