Enter data into TextBox in VB6

Hi

How can I control the TextBox that the user only able to enter Number to TextBox ? This meaning that the other keyboard keys be inactive to write.

Thank you

Try this:

If Not IsNumeric(MyTextbox) Then
   MyTextbox = ""
   MsgBox "Only numbers please"
   MyTextbox.SetFocus
End If

Why would you ask a question as vague as this and get a perfectly good reply as above then privately message me telling me that I don't know anything about programming. Do you think that this will encourage other community members to help you?

Try this:

If Not IsNumeric(MyTextbox) Then
   MyTextbox = ""
   MsgBox "Only numbers please"
   MyTextbox.SetFocus
End If

You could also try something along these lines...

Private Sub Text1_KeyPress(KeyAscii As Integer)
  If KeyAscii >= 65 And KeyAscii <= 90 Then
    Beep
    KeyAscii = 0
  End If
End Sub

This is a simplified version which just disallows uppercase letters. You can play with it to filter out other characters.
