Since there are more than three Textboxes in my application needed the user input number from 0
to 9999, I want a function which could deal with
the input errors, and give me an example to tell
how to call the function. Thanks!

This is how I would write a quick function:

Private Function ValInput(sInput As String) As Boolean
If IsNumeric(sInput) = True Then
If Val(sInput) >= 0 And Val(sInput) < 10000 Then
ValInput = True
Else
ValInput = False
End If
Else
ValInput = False
End If
End Function

This example doesn't let the user leave the text box if the input doesn't pass validation. I'd probably add a msg box.

Private Sub Text1_LostFocus()
If ValInput(Text1.Text) = False Then
Text1.SetFocus
Text1.SelStart = 0
Text1.SelLength = Len(Text1.Text)
End If
End Sub

The IF statement here demonstrates calling the function.

I would do it even shorter:

Private Function ValInput(sInput As String) As Boolean

If Not IsNumeric(sInput) = True Then exit function
If Val(sInput) < 0 And _
Val(sInput) > 10000 Then Exit Function

ValInput = True
End Function
