 |
|
Waits for a region of a window to change or stop changing by using GDI bitmap functions and MD5 hashes. Requires Windows Vista or Windows XP. Earlier versions of Windows can be supported by using PhiLho and Laszlo's binary encoding libraries, although they're much slower. Details included in the scripts.

Really nice function. Amazingly compact.
Since I know some people have asked for this, I'm surprised no one replied. I suspect it's definitely getting used though! |

I was already aware of this script, but now I actually read it. Excellent stuffs!
I have a suggestion. Use DeleteDC, not ReleaseDC, for hcdc. |

Thanks Titan.
The script certainly look interesting, but I cannot get it to work. I am sure it is just my incompetence. Specifically, I cannot see what the following line does
| Code: |
hwnd := WinExist(t)
|
WinExist does not seem to be a function in the documentation, and hwnd is always 0x0.
An example script just measuring change in the active windows would be very good.
Regards,
David |

WinExist() is a built-in function, maybe you need to update your version of AutoHotkey. Here is a working example:
| Code: | #Include RegionWaitChange.ahk
Run, notepad ; open notepad
WinWait, Untitled - Notepad ; wait for window to exist
ControlSetText, Edit1 ; delete any current text
MsgBox, Notepad is empty`, press F12 to fill it with random text.
; monitor the region of 100px width and height from coordinate (10, 10):
RegionWaitChange(10, 10, 100, 100, "Untitled - Notepad")
; once the region changed the script will continue here:
MsgBox, Notepad has changed! (RegionWaitChange completed)
WinClose
ExitApp
F12::
VarSetCapacity(dots, 5000, Asc(".")) ; fill a variable with something
ControlSetText, Edit1, %dots%, Untitled - Notepad ; change the text on notepad artificially
dots = ; free variable
Return |
If you still can't get your script to work please post it.

Thanks a lot Titan! It works like a charm! One use of this script would be when you start an operation that takes several minutes to finish. It would then be good to be able to push a single hotkey which would monitor the entire screen (maybe even double screens  ) and make a sound when the screen changes. |

Thanks, I appreciate that. I originally wrote this for my game macros but then realized it could be used for other purposes such as event handling in the cases you mentioned. I believe it was a long requested feature as well.

Ive just combined this with Rolands Gui from his wincut script to make it even easier for newcomers.
| Code: | #Include RegionWaitChange.ahk
+#LButton::
CoordMode, Mouse
MouseGetPos, sx, sy, win
WinGettitle,title, ahk_id%win%
Gui, +lastfound +alwaysOnTop +toolwindow -caption
Gui, Color, 00FFFF
WinSet, Transparent, 50
Gui, Show, noActivate
Loop {
if !getKeyState("LButton", "p")
break
MouseGetPos, x, y
Gui, Show, % "x" sx "y" sy "w" x-sx "h" y-sy
} WinGetPos, gx, gy, w, h
Gui, destroy
msgbox %title%
RegionWaitstatic(gx, gy, w, h, title)
msgbox
exitapp
return |
