Autoit crash?

[MaximusCZ]

#include "_MouseOnEvent.au3"
#include <Misc.au3>
_MouseSetOnEvent($MOUSE_WHEELDOWN_EVENT, "aa")
Func aa()
    ToolTip ("a")
            While _IsPressed ("04") == false
                ToolTip ("f")
            WEnd
    ToolTip ("e")
EndFunc

while 1
WEnd

Code above.
I run the code, and click middle mouse button repeatedly, observing tooltip to follow flow.

After several seconds (or several tries, usually less than 10), the tooltips stops changing (always ends on "e")

The rest of the script becomes unresponsive.

After CTRL+Break this is the output in console

Whats happening?
 

 

If I ommit the _IsPressed check inside the function, the script is running OK indefinetly.

_MouseOnEvent.au3

Probably due to the function being called recursively each time you press the middle button. Try disabling the _MouseSetOnEvent at the beginning of your function and then enabling it at the end.

[MaximusCZ]

@Danp2 _MouseSetOnEvent is called before function declaration. Its in a same space as #include

I was suspecting that the AA function was being called recursively due to the existing _MouseSetOnEvent command. I was suggesting that you disable this functionality while within the AA function. Another option would be to add a ConsoleWrite at the beginning of the function so you can observe each time the function is executed.

@Danp2

Tested it with Consolewrite at the beggining of function and I can confirm that it gets called once per "mouse button down event". Holding the mousebutton does not call the function multipletimes.
The problem persist even when I make another press only after tooltip "e" is visible, indicating exiting the function. After several tries it just exits the function and never enter again.
Its not like its then just waiting in while loop, as stopping the script reveals it was actually hung.

[MaximusCZ]

Correction

After adding "Tooltip ("w")" inside while loop, I can confirm the scipt is not actually hung. It just doesnt call the function again.
Strange that CTRL+Break is unable to gracefully stop the function, tho. Sadly the same seems to apply when tryin to stop the script before a single keypress is made -- every time at any script

If you are gonna repeatedly use _IsPressed, you should be using the OpenDLL method. See the help file.

And I strongly suspect you need to throw a Sleep in there too, even if it is only Sleep(10).

What's this for?

[MaximusCZ]

@TheSaint

I need to send ESC before and after I hold MMB mouse to switch program into mode where MMB drag can be utilized.
But when I want to close modified window, the second ESC cancels "close without saving" dialog.
I wanted to record distance traveled while holding MMB to be able to choose to omit second ESC, but ran into this problem

@TheSaint

I have tried both adding Sleep in while loop and calling uuser32.dll only once at the begining and then passing the handle to _IsPressed, no difference.

[TheSaint]

If I recall correctly, ESC can end a script, so that might be part of your problem??? Or maybe that is just a GUI window???

I also seem to recall you can change that behavior???

Best way to quickly test that I guess, is try another key and see what happens ... perhaps SHIFT.

But definitely use the DLLOpen method, to help narrow down possibilities ... Sleep too.

What value Sleeps have you tried? And where are you putting them? I see two places where you should use Sleep.

Have you tried something like the following?

#include "_MouseOnEvent.au3"
#include <Misc.au3>
_MouseSetOnEvent($MOUSE_WHEELDOWN_EVENT, "aa")

Global $dll = DllOpen("user32.dll")
While 1
    Sleep(50)
WEnd
DllClose($dll)

Func aa()
    ToolTip ("a")
    While _IsPressed("04", $dll) == false
        ToolTip ("f")
        Sleep(50)
    WEnd
    ToolTip ("e")
EndFunc

I would also incorporate a Timer that checks periodically for a Key press to allow exiting your While 1 loop.
