WinWait doesn't wait (The sample doesn't work) please help

[ywangperl]

The following code has the Run("notepad.exe") commented. I expect the code will wait till I manually start notepad. But the scprit exits without waiting (this is *NOT* expected). If I start a notepad and run the script, the script works fine.

I have spent hours on it without success. Please help!

-------------------------------- autoIt example doesn't work for me------------------------------

Example()

Func Example()
    ; Run Notepad
    ;Run("notepad.exe")

    ; Wait 10 seconds for the Notepad window to appear.
    WinWait("[CLASS:Notepad]", "", 10000)

    ; Wait for 2 seconds to display the Notepad window.
    Sleep(2000)

    ; Close the Notepad window using the classname of Notepad.
    WinClose("[CLASS:Notepad]")
EndFunc   ;==>Example

change the 10000 to 10, run the script again, then re-read the Help file..

Your script is working as expected for me.

What version of autoit are you running, and do you have any instances of notepad running that you missed?

[jdelaney]

Don't include any third param if you want to wait forever for the window...click this link:

winwait

Also, are you expecting only new instances to be closed?  You'll need to script for that.  The example closes the first instance of a window with class = notepad.

Thanks for the answer. Here are the commands that I have tried on 2 PCs (v3.3.10.2). I am expecting the code will wait forever. But6 is is not happening. Confused -Y

 

Example()

Func Example()

    ;WinWait("[CLASS:NotepadNotExist]", "", 10)
    WinWait("[CLASS:NotepadNotExist]")

EndFunc   ;==>Example

I am running a slightly older version than you (3.3.8.1), so maybe that has something to do with something, but when I ran this line of code:

WinWait("[CLASS:NotepadNotExist]", "", 10)

the script exited about 10 seconds after I started it. I ran this line of code:

WinWait("[CLASS:NotepadNotExist]")

and after about a minute and a half I manually stopped the script. Edited April 15, 2014 by somdcomputerguy

Run this:

$hwnd = WinWait("[CLASS:NotepadNotExist]")
Consolewrite($hwnd & @crlf)

post back the output.

[ywangperl]

Something is very wrong. This following script won't print anything, no matter if there is a notepad indtance.

 

Local $sString = "running autoIt"
ConsoleWrite($sString & @CRLF)
$hwnd = WinWait("[CLASS:NotepadNotExist]")
Consolewrite($hwnd & @crlf)

$hwnd = WinWait("[CLASS:Notepad]")
Consolewrite($hwnd & @crlf)

What program has a class of NotepadNotExist? Notepad.exe uses Class:Notepad, so I'm not sure what it is you're attempting to do here.

[somdcomputerguy]

I'm pretty sure that weird classname was just to test the functionality of the WinWait function.

[somdcomputerguy]

Hmm.. If I run this code:

Run("notepad.exe")
Local $sString = "running autoIt"
ConsoleWrite($sString & @CRLF)
$hwnd = WinWait("[CLASS:NotepadNotExist]", "", 1)
Consolewrite($hwnd & @crlf)
$hwnd = WinWait("[CLASS:Notepad]", "", 1)
Consolewrite($hwnd & @crlf)

I get this:

running autoIt
0
0x0013054A

If I run this code:

Local $sString = "running autoIt"
ConsoleWrite($sString & @CRLF)
$hwnd = WinWait("[CLASS:NotepadNotExist]")
Consolewrite($hwnd & @crlf)
$hwnd = WinWait("[CLASS:Notepad]")
Consolewrite($hwnd & @crlf)

I get this:

running autoIt

and the script will keep running (doing nothing because WinWait waits forever for a program with a classname of NotepadNotExist) until I manually end it.

Yeah, I'm not paying very good attention here.

I ran the test scripts and they work just fine for me as well, running it on 3.3.11.3. WinWait is waiting when I try it.

They're working fine and as I expect them too, with the older version I run.

 What do you think is 'wrong' here...you will never find a window with that class=NotepadNotExist, one does not exist...and there is no timeout, so youre deadlocked...what do you expect to occur?  AutoIT is linear, so you must fulfill the first winwait prior to executing the second winwait.

[ywangperl]

Something is *wrong* on that script. The script just "exit" to Dos prompt. Nothing happened.  When I get home  I tried this sample using (v3.3.8.1). Nothing is printed to stdout.

Local $var = "Test"
ConsoleWrite("var=" & $var & @CRLF)

Thank everyone for your time and attention. I am stuck on this:(.     Problem 1: ConsoleWrite doesn't work.  Problem 2: WinWait exitd when the window doesn't exist.    If anyone has a wild guess, please share it with me.  (They happended on 2 PC at work and one PC at home)

Are you running it with #RequireAdmin? If you are script will appear to exit in scite while infact a new instance has been spawned.

Explain how you are actually running it because "The script just "exit" to Dos prompt" suggests you are starting it from that.

[ywangperl]

Note1: w is an Administrator

c:_TAF>whoami
w

c:_TAF>cat e2.au3
Local $var = "Test"
ConsoleWrite("var=" & $var & @CRLF)


c:_TAF>"c:Program Files (x86)AutoIt3AutoIt3.exe" e2.au3

c:_TAF>

Note 2: nothing get printed.

[JohnOne]

Nothing will be written to console window when running exe like that.

Unless there is something else relevant about your script you should add.

If so, why not explain everything instead of needing it dragged out.

[ywangperl]

Story:

Problem 1: the WinWait wont' wait for the notepad (When there is no notepad window, the script exit to DOS promptly)

               I tried to WinWait an non-existing window and hoping the script will "wait". But the script exists to DOS right away

Problem 2: To debug, I used ConsoleWrite to print STDOUT. But nothing get printed to STDOUT.

Both WinWait and ConsoleWrite are simple comands and they don't work for me. I am asking for help here.

Thanks again

How are you initiating the script...post back the actual command as well.

If it's not compiled as a console app, and you are running through a console, there will be no output.  You can do file writes instead.

FileWrite
