WinExists with timeout

[SorryButImaNewbie]

Hello!

I read around a bit (not much, helpfile and a quick google search and forum search here), sorry if this has been asked before.

I have a code snippet I wrote:

$Wait = WinExists($TopUpName & ".pdf - Adobe Reader", "", 5)
    If $Wait = 0 Then
       Return
       MsgBox(0, "Title", "Nem találtam")
    Else
       WinClose($TopUpName & ".pdf - Adobe Reader", "")
       MsgBox(0, "Title", "Megtaláltam, szar vagyok és nem zárom be")
    EndIf

Before I used winwaitactive, but I realized that somehow the pdf wasn't neceserry active after it has been opened, so I changed it to WinExists. I saw that there are only 2 parameters for winexists, but when I tried to run it just for the hell of it, It run down without an error. (MsgBox are there just for me too see whats happening)

My question is, whats happening? Does Autoit just skip the last parameter? Is this works as a timeout ? (I doubt that), is there a way to give time out for WinExists? (I'm sure there is) How?

Thank you for your time!

Edit:Quick edit for a grammar mistake

That function just tests if the window exists at the time of calling.

There is no ambiguity there, you're probably looking for WinWait.

Thanks Master @JohnOne!

Yeah now that you say,I think I would be better with simply using WinWait, but what happens in the backround in the above case? Does Autoit just ignore the 3. parameter, because there can't be a third?

(Changed to WinWait)

I'm not sure I understand, WinExists only takes 2 parameters, title of window, and text of window.

there is no 3rd.

[SorryButImaNewbie]

Yeah but in the 1. post ,in the code, there are 3 parameters (variable + string, and empty one, and a number) and it runs without any error that I can see.

I thought when I started to run it that it wont even execute, but it did

OK, I see, and am unsure of the answer, unless it's been discussed before only a code dev would know that.

I too would have expected it to give a "wrong number of parameters" error.

There are a few possible answers, but they'd all be guesses from someone who does not have access to the AutoIt3 source code.

Actually.

WinExists("somebullshitnamethatdoesnotexist", "samewithtext", 3)

error: WinExists() [built-in] called with wrong number of args.

I expected the same, interesting 0.o

I got the same results as J1.
