Winwait for winexist

[kjcdude]

I need to figure out how to wait for a window to exist.

The window pops up in the background, and it can take a few seconds to popup.

Right now i just have it sleep for a few seconds then force activate it, but i would feel more confident if there is a more secure version.

Run("notepad.exe")
;
; Wait for the window to exist
;
WinWait("Untitled")
;
; Wait for the window to become visible
;
Do
    Local $Wait = WinGetState("Untitled")
    Sleep(10)
Until BitAND($Wait, 2)
;
; Activate the window
;
WinActivate("Untitled")

you can also switch the 'run' command with 'RunWait' which will have the same results

Hello Armand,

you can also switch the 'run' command with 'RunWait' which will have the same results

Do you have an example of this? My understanding of RunWait is that it will pause the script until the process is closed.

;~ Runs an external program and pauses script execution until the program finishes.
RunWait( "notepad.exe" )
ConsoleWrite( "Script execution will now continue..." & @CRLF)

and as i understand from his question he doesn't need it to continue while he is waiting

PWNED!

Indeed. My understanding is that he needs to do something with the window that belongs to the launched process.

I took Emperor's working example and replaced 'Run' with 'RunWait' as you suggested. Then I ran it with debug mode turned on.

Notepad appears and the debug shows that the script has paused here:

Line: @error-@extended: Line syntax
0001: 0-0: #AutoIt3Wrapper_run_debug_mode = Y
0002: 0-0: RunWait("notepad.exe")

It does not resume until I close that instance of Notepad. Once I do that, the script pauses on this line:

0006: 0-0: WinWait("Untitled")

It does not resume until I manually open a new instance of Notepad.

These behaviors do not manifest in the original example. This means one of two things:

1 ) My implementation of 'RunWait' is incorrect

2 ) RunWait will not have the same result regardless of implementation.

I don't mean to beleaguer the point; I'm just interested in seeing how you were able to do it.

anyhow since we're playing with it... and i am so freakin' sleepy... it's 9am here and i've been up all night with my stupid script!

Opt("WinTitleMatchMode", 4)

$proc = Run("Notepad.exe", "", @SW_SHOW,7)
While 1
    If WinWaitActive("Untitled") = 1 Then ExitLoop
;~ Sleep(1000); in case it takes that process a while to load...
WEnd

Send("Not PWND, was too damn tired to PWN :)",1)

While WinExists($proc)=1    
WEnd

Exit

just in case you are realy wondering, 'runwait' runs a process and holds the script untill the child process doesn't exists anymore!

Well the program is actually launched from another program, so i have no control over how it opens.

Right before it opens my script presses enter then waits 10 seconds and forces the new window to come to the front.

Hello 'kjcdude',

Emperor's suggestion should still be valid in your scenario. Simply remove 'Run( "notepad.exe" )' from the example and replace window titles as appropriate. Let us know if it works.
