Question regarding WinActivate

[Hooch]

When you call WinActivate() what is the behaivor if the window that is called to be activated is already active? Do I save processing if I do a ....

If WinActive("window1") Then
    WinActivate("window2")
endIf

... or does the function check that and not bother if the window is already active?

I just want to be as efficient as possible....

WinActivate() will give the focus to the specified window. Nothing happends when the Window already has the focus....

ah ok, so with the extra if clause Im costing myself cpu cycles..... thanks.

I knew it worked fine either way, I just wasn't sure which was more efficient.

WinActivate("E:\AutoIt")

Sleep(100)

$t = TimerInit()
If NOT WinActive("E:\AutoIt") Then WinActivate("E:\AutoIt")
ConsoleWrite(Timerdiff($t) & @CR); gives +/- 0.6

$t = TimerInit()
WinActivate("E:\AutoIt")
ConsoleWrite(Timerdiff($t) & @CR); gives +/- 250.0

so the 1st method is way better

wOuter,

This test is misleading because the AutoIt WinWaitDelay option defaults to 250ms. If set to 0ms, the time to activate a window is reduced from 251ms to about 0.19ms on my PC. While I don't recommend a delay of zero milliseconds, I often set WinWaitDelay to 5ms.

My results from 10 runs using Opt("WinWaitDelay", 0):

1. Not activating the window if already active: 0.17ms to .22 ms

2. Always activating the window: 0.16ms to 0.23ms

stupid me lol.

w/ the opt()

1st try

0.594628697874134
0.93590351501102

2nd try

0.846656363694903
0.655575459023735

3th try

0.653381101656964
0.430464892331018

4th try

2.20084589739762
3.30013434841021

i think that it doesnt really make a diffenence ...

and i also tried this

$bx = 0
$ax = 0

WinActivate("E:\AutoIt")

Opt("WinWaitDelay", 0)

Sleep(100)

For $i = 1 to 100

$a1 = 0
For $a = 1 To 100
    $t = TimerInit()
    If NOT WinActive("E:\AutoIt") Then WinActivate("E:\AutoIt")
    $a1 += Timerdiff($t)
Next

$b1 = 0
For $b = 1 To 100
    $t = TimerInit()
    WinActivate("E:\AutoIt")
    $b1 += Timerdiff($t)
Next

If $a1 < $b1 Then 
    $bx += 1
;MsgBox(0, '', "If: (" &  $b1 - $a1 & ")")
Else
    $ax += 1
;MsgBox(0, '', "Normal: (" &  $a1 - $b1 & ")")
EndIf

Next

MsgBox(0, '', $ax & @CRLF & $bx)

IT ENDED EXACTLY IN 50-50
