after the user clicks it once, disable the button until you want to allow the user to click it again.

command1.enabled = false
0

or create a public boolean variable called answered or something and use it like this


Option Explicit
Dim answered as Boolean


Private Sub Form_Load()
answered = FALSE

Private Sub Command1_Click()
If answered = FALSE Then
   'do some calculations
   answered = TRUE
Else
   Exit Sub
End Sub

I can see where this would be useful. The first answer given is better, since the user doesn't think that the button is still active.

If you use the second method, be sure to make edits to each textbox (or, more accurately, variable involved in the calculation) allow the command button to come back to life.

You could combine the two techniques  into your program like this:

Option Explicit
Dim answered as Boolean

Private Sub Textbox1_Change()
If answered = TRUE then
   'Allow calculations again
   answered = FALSE
   Command1.enabled = TRUE
End If

Private Sub Command1_Click()
If answered = FALSE Then
   'Insert happy calculations
   answered = TRUE
   Command1.enabled = FALSE
Else If answered = true then
Else
   msgbox "error"
End If
Exit Sub



You'll have to add the code from textbox1_change to all fields that change the data used by your calculations.
