Code to automatically pause the script if a new window open or existing active window crashes

[erloyaamit]

Need help on following requirement

Code to automatically pause the script if a new window open or existing active window crashes

Scenario: We've a tool where we add server entries based on the inputs in Excel sheet. Now the requirement is whenever a new window (e.g Notepad, Browser) is opened OR the tool itself crashes, the script should Pause immediately.

The script should resume from that point again once the active window is switched to tool that I am using.

Thanks in Advance

Define "existing active window crashes"

[MikahS]

Wouldn't checking with a

WinActive

to see what the title is and if its not your 'window' then put it into a function that checks the active window, instead of running the rest of the script.

WinWaitActive

Pauses execution of the script until the requested window is active.

WinWaitActive ( "title" [, "text" [, timeout = 0]] )

You should check the help file for example script.... :thumbsup:

If i'm understanding you correctly, your going to need 2 scripts. 

in your script (the one you want to pause) you'll need to add these lines (or something similar)

HotKeySet("{1}","_Pause")
$paused = False

"{1}" being whatever key you can get away with stealing from the computer

and this function

Func _Pause()
    If $paused Then
        $paused = False
    Else
        $paused = True
    EndIf
    While $paused
        Sleep(50) ; so you don't overrun your cpu, you can increase this to suite your needs but if you want near real time leave it at 50
    WEnd
EndFunc

then in the other script you'll need to write the winactive monitor portion in a while loop and send the hot key based on your logic

once your logic has passed use a Send("{1}") and that should pause your other script, using a Send("{1}") again should un-pause it and allow it to pick up at the exact spot it left off.

How should the OP handle the "crashed window" you guys?

[MikahS]

@JohnOne use WinList() to check to read all windows and put it into a for loop to check the 2D array made,  if this "tool" has crashed it will not be there, if it's crashed re-open it with a Run() call. This can be done simply with an AdlibRegister every couple of seconds. 

@232showtime I'm very sure we are checking to see what is active, not trying to make it active, as per OP's statement.

@tlman12 toooo much this is simply done with putting it into a function with a simple while loop that checks to see what window is active, then if the window we want becomes active, get out of the function.

Is the new window an enabled popup of the application window?

If the application 'crashes' (hangs) the winstate probably get's modified to NOT be enabled.

You can create functions to check for both conditions via:

AdlibRegister

One function that checks for the enabled popups:

_WinAPI_GetWindow(); where the option = 6

One function to check the window state:

$iState = WinGetState
If Not BitAND ($iState,4) Then
    ; check for about 10 seconds...if it fails, then exit...you crashed
EndIf

Edit; just saw your post...You should be using the handle of the window, then you can check if it doesn't exist:

If Not WinExists($hYourWindow) Then Run()

Would have looked at using 

_WinAPI_IsHungAppWindow()

[MikahS]

@JohnOne yes I would use that also, but what if a window crashed and closes right away

[JohnOne]

Well that is the question I asked the OP, only they know what happens to it.

[MikahS]

Absolutely, you are right. I just gave explanation of what to do on either a hanging crash or an actual closing application crash.
