 Posted: Sat May 17, 2008 9:10 pm Post subject: What's Up with Vista and SendInput, SendPlay, & Hooks? |
 |
|
There have been scattered reports on the forums here about issues with SendInput and SendPlay using Vista. I've had difficulties also. Some suggestions involve using compatibility mode or running as administrator. Right now, I have UAC disabled, and I can't use SendInput with my Right Alt key-triggered hotkeys, because the Alt gets stuck down even with #HotkeyModifierTimeout 0.
http://www.autohotkey.com/forum/viewtopic.php?t=29607
SendPlay has worked better, if I have the following in the auto-execute section of the script: | Code: | SetBatchLines -1
SendMode Play
Process, priority, , High |
and I don't have autohotkey.exe running in compatibility mode.
I've also had problems using a LButton hotkey with a #IfWinExist directive (double-click becomes effectively disabled).
It seems as though however AHK does keyboard/mouse hooks gets weird in Vista. Is there a common source of these issues that could be fixed? Would a keyboard/mouse hook AHK helper running as a service avoid these problems? Thanks. |

The only problem I recall having with SendInput or SendPlay is that SendPlay doesn't work at all.  I have UAC enabled.

Does this happen all the time, intermittently, or only when the window is active?
Could you post some example scripts, so that I may see these issues for myself? |

Since I'm constantly editing my scripts, I don't have handy examples for you. However, using the right alt key to trigger a SendInput resulted in a stuck Alt key: | Code: | | >!v::SendInput %longvariable% |
Also, using SendInput in general (triggered by a combo hotkey for example) kept the following from working after it was triggered unless I switched windows and regardless of whether I had #UseHook on or off: | Code: | | `::PostMessage, 0x112, 0xF060,,,A ; 0x112 = WM_SYSCOMMAND, 0xF060 = SC_CLOSE (run with highest privileges) |
At least, I think it was a stuck Alt key; there was all sorts of weirdness.
SendPlay does work for me with UAC off, and quite nicely.
Here's the actual code for the LButton issue, which I've removed from my main script. The issue happened with neither window actually existed, but the directive was (I believe) for a window group: | Code: |
GroupAdd, noclose, EasyCapture
GroupAdd, noclose, Google Calendar - Mozilla Firefox
#IfWinActive EasyCapture
`::PostMessage, 0x112, 0xF020,,,A
#IfWinActive
#IfWinActive Google Calendar - Mozilla Firefox ; Hide Window
`::WinHide A
#IfWinActive
#IfWinExist, ahk_group noclose
LButton:: ; Hide Google Calendar instead of close when close button is clicked
CoordMode, Mouse, Screen
MouseGetPos, x, y, hwnd
WinGetTitle, title, ahk_id %hWnd%
IfInString, title, Google Calendar - Mozilla Firefox
{
SendMessage, 0x84,, (x & 0xFFFF) | (y & 0xFFFF) << 16,, ahk_id %hWnd%
If ErrorLevel in 9,12,14,20 ; 20 is for Close box but Vista/Aero bug in WM_NCHITTEST
WinHide ahk_id %hWnd%
else
Click down
}
IfInString, title, EasyCapture
{
SendMessage, 0x84,, (x & 0xFFFF) | (y & 0xFFFF) << 16,, ahk_id %hWnd%
If ErrorLevel in 9,12,14,20 ; 20 is for Close box but Vista/Aero bug in WM_NCHITTEST
PostMessage, 0x112, 0xF020,,, ahk_id %hWnd%
else

}
else

This doesn't give me any problems. What would be typical contents for longvariable?

So when you run that code, double-click doesn't work?
I've tried the code you posted with and without my two main scripts, which use mouse and keyboard hooks. I wasn't entirely sure what to look for, though. Is it an intermittent issue?
Some information that might be useful:
- Do you have the latest version of AutoHotkey (v1.0.47.06)? I do.
- Are you using 32-bit or 64-bit Vista? I'm on 32-bit Vista.
- Do you use Logitech SetPoint, Microsoft IntelliMouse or similar? I don't.
- Can you reproduce these issues with no other scripts or similar applications running?
