WAiting before carrying out command

Hi, how do I;

Wait 3 seconds after a user has stopped typing in a specific text box in my program, and then carry out some code.

Heres 1 way:

Place Timer control on form. Timer1.Enabled = false
Timer1.interval = 1000

Then if your textbox is Text1, this should work:

VB Code:

Dim I_CHANGED As Integer
 
Private Sub Text1_Change()
I_CHANGED = 0
Timer1.Enabled = True
End Sub
 
Private Sub Timer1_Timer()
    I_CHANGED = I_CHANGED + 1
    If I_CHANGED > 2 Then
        MsgBox "DONE"              'Or Call the Sub that contains the code you want executed.
            Timer1.Enabled = False
    End If
End Sub

Try the Sleep API

VB Code:

Private Declare Sub Sleep Lib "kernel32" (ByVal dwMilliseconds As Long)
 
 
Private Sub Form_Load()
Debug.Print "Start"
Debug.Print "Wait 3 Seconds"
Sleep 3000
Debug.Print "Go"
End Sub

Code:

---

   
    Dim dblClock As Double
   
    dblClock = Timer
    While Timer < dblClock + 3 ' Wait 3 seconds
        DoEvents
    Wend

---

BTW, you don't need a timer control to run the above code.

Might I suggest a slight mod?

Code:

---

   
    Dim dblClock As Double
   
    dblClock = Timer
    While abs(Timer - dblClock) < 3 ' Wait 3 seconds
        DoEvents
    Wend

---

This will stop it running all day if it just happens to execue at midnight.

Purists would probably want to use Now() instead of Timer, but I think it's not worth the trouble for the odd time the code may execute at midnight.

Now I'm sure somebody will say 'Yes, but the Timer uses less cpu time'. I don't buy that. The above code may SEEM to use more cpu time while the loop is running, but it should give up any time slices needed by other apps if required - so I don't think it matters. Must try it sometime with a test app and see if it has any real effect.
