要點：

       1.通過計時器計算兩次點選的時間判斷是否是雙擊

例項程式碼；

      

Local $hTimer = TimerInit()
$DBDown= 0
  While 1
        Switch GUIGetMsg()
           Case $GUI_EVENT_CLOSE
                ExitLoop
Case $GUI_EVENT_PRIMARYDOWN   ;計時器校驗是否是雙擊
$fDiff = TimerDiff($hTimer)
If $DBDown = 0 Or $fDiff > 500 Then
  $DBDown = 1
  $hTimer = TimerInit() ; Begin the timer and store the handle in a variable.
Else
  If $fDiff < 500 Then
 $DBDown = 2
  Else
 $DBDown = 0
  EndIf
  EndIf
Case $GUI_EVENT_PRIMARYUP
If $DBDown = 2 Then
  $DBDown = 0
 Local $aArray = GUIGetCursorInfo($hDesk)
 If @error = 0 Then  ;事件
Switch   $aArray[4]
 Case $picBuff[1]
 MessageBox(0,0, "HELLO")

 EndSwitch
  EndIf 
EndIf
        EndSwitch
    WEnd
