Hello everyone I am encountering a strange problem with timers... i.e wrong time difference . This is an test script made by me to compare Arrays & Maps in terms of speed, I wanted publish the results in my Maps topic, so I am hiding the question in the spoiler to prevent spoilage If you run the script(s), you can see that sometimes the time difference is >1 but the actual difference is almost instantaneous, I don't know what is causing the problem, I think the problem is in my end this time because I used both native and UDF functions and they return identical results... However I spotted something interesting in the documentation for TimerDiff: "Remarks: Some processors are known to cause the function to return incorrect result." Hmmm.... is my processor the culprit? Or is something wrong in my script... Thanks in Advance! TD P.S It was hard to write in the dark spoiler

Here is my wrapper for SetTimer and KillTimer APIs. AutoIt already has its own, but I tried to make it as simple as I could. #include-once Global $g_avSimpleTimers = [[0, 0]] Func TimerSet($vFunction, $uInterval) Local $hFunction = DllCallbackRegister($vFunction, "none", "HWND;UINT;UINT_PTR;DWORD") If ($hFunction = 0) Then Return 0 Local $uTimerId = DllCall("user32.dll", "UINT_PTR", "SetTimer", _ "HWND", 0, _ "UINT_PTR", 0, _ "UINT", $uInterval, _ "ptr", DllCallbackGetPtr($hFunction))[0] If ($uTimerId = 0) Then DllCallbackFree($hFunction) Return 0 EndIf ReDim $g_avSimpleTimers[$g_avSimpleTimers[0][0] + 2][2] $g_avSimpleTimers[$g_avSimpleTimers[0][0] + 1][0] = $uTimerId $g_avSimpleTimers[$g_avSimpleTimers[0][0] + 1][1] = $hFunction $g_avSimpleTimers[0][0] += 1 Return $uTimerId EndFunc Func TimerUnset($uTimerId) If ($g_avSimpleTimers[0][0] = 0) Then Return False Local $iCount = $g_avSimpleTimers[0][0] For $i = 1 To $iCount + 1 If ($g_avSimpleTimers[$i][0] = $uTimerId) Then DllCall("user32.dll", "BOOL", "KillTimer", _ "HWND", 0, _ "UINT_PTR", $uTimerId) DllCallbackFree($g_avSimpleTimers[$i][1]) For $j = $i To $iCount - 1 $g_avSimpleTimers[$j][0] = $g_avSimpleTimers[$j + 1][0] $g_avSimpleTimers[$j][1] = $g_avSimpleTimers[$j + 1][1] Next $g_avSimpleTimers[0][0] = $iCount - 1 ReDim $g_avSimpleTimers[$iCount][2] Return True EndIf Next Return False EndFunc Example: #include "Simple Timers.au3" Global $t1 = TimerSet(Foo, 500) Global $t2 = TimerSet("Bar", 1000) MsgBox(0, "", "Check the console.") TimerUnset($t1) MsgBox(0, "", "Check the console again.") TimerUnset($t2) ;Not necessary if you are exiting the script Func Foo($a, $b, $c, $d) ConsoleWrite(">Foo" & @CRLF) EndFunc Func Bar($a, $b, $c, $d) ConsoleWrite("!Bar" & @CRLF) EndFunc Download both UDF and example:
