AUInfo Reading info under mouse on 2560x1440 screen wrong


Recommended Posts

Hi All,

I'm trying to run a script to fire when a pixel at a certain location on the screen changes to a particular colour, however auinfo is unable to measure the colour where my cursor is due to my high resolution - 2560x1440 on a 13.3" laptop. Does anyone have a workaround or a fix for this?

If I move my mouse to the bottom-right corner of the screen auinfo reports the mouse position as about 1280x720, 1/2 my actual resolution.

Thanks!

That must be one hell of a monitor to achieve that resolution on such a small screen. What does @DesktopHeight and @DesktopWidth return when your script is running?

That looks like a sweet laptop. :)

@DesktopWidth = 1280

@DesktopHeight = 720

Actual Screen resolution 2560 x 1440, so it's exactly 1/2 of the actual resolution. I've heard the same with other people with these high resolutions. I get the same result if I use a pixel colour app to show the colour of the pixel under the cursor, seems apps just haven't caught up yet.

There's probably a way of programatically showing a virtual cursor location on screen as I move the mouse so I can see where it is actually resting and then take a location and colour reading?

Not sure what you mean with a gradient but if you can make a full screenshot to a bmp then you can grab every pixel you want or load it into gdi functions to manipulate. Search for findbmp and you will see how to get your screenpixels in a huge array. Other options are in the forum to run a fasm script in assembly to quickly analyse pixels.

Could this be the cause

Thanks. By gradient what I mean is I am wanting to read a pixel colour change if a message appears, however the message itself has a gradient from mid blue at the top to dark blue at the bottom of the background, it is not a single colour. I'll have a look around for those tools you mentioned - cheers.

I threw this script together, I'll try it tonight and see where the cursor moves to and the colour it picks up, then just increment/decrement the values until it's in the right position, at which point I can convert the decimal colour to hex to see if it's roughly the right colour (eg http://www.w3schools.com/tags/ref_colorpicker.asp).

$width = 1000
$hight = 700
MouseMove($width,$hight)
$pixcolour = PixelGetColor($width,$hight)
$pixhex = hex($pixcolour,6)
ClipPut($pixhex)
MsgBox(0, "Pixel Colour", "Dec: " & $pixcolour & " Hex: " & $pixhex)

I'd guess that you are running with a dpi scaling setting of something other than 100%. Sounds like 200%. AutoIt doesn't have the resource manifest HighDpi set, so screen operations get converted and scaled. I can't think of an easy fix. If we manifest AutoIt for high dpi then it would work, but all the GUI controls would break at the same time.

Aha! Yep, just had a look at my display settings, you are right.

If I drag it back to the left of the display setting everything on the screen is so small lol but if I run my mouse position script above it now gives me my correct screen resolution if I put my mouse in the bottom-right corner.

Hmm, ok, so looks like I'm stuck.

I'm not familiar with how to do that Bert?
I looked through the info that auinfo provided but there is no information change when the button becomes active so the colour change was the best option I could see.

That being said, the button is out of the range for AutoIt due to my high DPI scaling, so even if I could read the change I couldn't click on the button lol.

Is it not something you could activate using ControlSend rather than clicking ?

check with the iuiAutomation thread in examples section and try if simplespy can reach your control (logically it should as its using the uiautomationcore.dll)

most likely the iuiAutomation stuff will have a property of the control if its active yes/no and as such no need to check based on the color.

      I have a weird problem with a ToolTip function.
      It seems that I can't reliably remove a tooltip from the screen if I originally created it by setting a tooltip text via variable, not a straight up string.
       
      Here's a simple script that I used for testing:
       
      After I remade the script into this, it started working just fine (stopped working after I fixed the array comparison):
       
      Basic idea of the script:
      You press F1 and a tooltip with some useful info shows up by the mouse cursor. It follows the cursor around until you press F1 again, then it copies the info to the clipboard and hides the tooltip.
       
      It almost seems like if I created a tooltip using a variable to set the text, then ToolTip("") most of the times just repeats the previous use of ToolTip function. If you try to add Sleep(1000) before ToolTip("") in the first draft of the script, you'll see what i mean (if it works the same for everyone, that is).
       
      Is this a bug or am I doing something wrong?

      Hey.
      Is there anything that does the same thing as this?
       
      Namely I'm talking about detecting when something has changed on screen.
      The FastFind library is crashing without any errors after running:
      FFSnapShot($left, $top, $right, $bottom, 0) FFSnapShot($left, $top, $right, $bottom, 1) $diff = FFLocalizeChanges(0, 1) And then trying to overwritite the old snapshot (0 or 1).
      If I use always different snapshot numbers its using too much memory and will eventually crash my pc.
      I tried downloading older versions but they're not working and the author is inactive.
       
      It takes 2 snapshots and compares them returning the area that has changed very quickly (left, top, right ,bottom).
      Can anyone help me do this?
      Looping PixelGetColor would require a bunch of extra code to my purpose and its not as efficient...
       
      Thanks

      This UDF allows to set an events handler for Mouse device.
       
      The beginning...
      I searched for a way to disable the Mouse Primary click, and be able to call some function when the click event is received...
      Big thanks to amel27 for this one, i only organized the whole stuff to UDF style.
       
      Example:
      #include <GUIConstantsEx.au3> #include "MouseOnEvent.au3" HotKeySet("{ESC}", "_Quit") _Example_Intro() _Example_Limit_Window() Func _Example_Intro() MsgBox(64, "Attention!", "Let's set event function for mouse wheel *scrolling* up and down", 5) ;Set event function for mouse wheel *scrolling* up/down and primary button *down* action (call our function when the events recieved) _MouseSetOnEvent($MOUSE_WHEELSCROLLDOWN_EVENT, "_MouseWheel_Events") _MouseSetOnEvent($MOUSE_WHEELSCROLLUP_EVENT, "_MouseWheel_Events") _MouseSetOnEvent($MOUSE_PRIMARYDOWN_EVENT, "_MousePrimaryDown_Event") Sleep(3000) ;UnSet the events _MouseSetOnEvent($MOUSE_WHEELSCROLLDOWN_EVENT) _MouseSetOnEvent($MOUSE_WHEELSCROLLUP_EVENT) _MouseSetOnEvent($MOUSE_PRIMARYDOWN_EVENT) ToolTip("") MsgBox(64, "Attention!", "Now let's disable Secondary mouse button up action, and call our event function.", 5) _MouseSetOnEvent($MOUSE_SECONDARYUP_EVENT, "_MouseSecondaryUp_Event", 0, 1) Sleep(5000) _MouseSetOnEvent($MOUSE_SECONDARYUP_EVENT) ToolTip("") EndFunc Func _Example_Limit_Window() Local $hGUI = GUICreate("MouseOnEvent UDF Example - Restrict events on specific window") GUICtrlCreateLabel("Try to click on that specific GUI window", 40, 40, 300, 30) GUICtrlSetFont(-1, 12, 800) GUICtrlCreateLabel("Press <ESC> to exit", 10, 10) GUISetState() _MouseSetOnEvent($MOUSE_PRIMARYDOWN_EVENT, "_MousePrimaryDown_Event", $hGUI) ;A little(?) bugie when you mix different events :( ;_MouseSetOnEvent($MOUSE_SECONDARYUP_EVENT, "_MouseSecondaryUp_Event", $hGUI) While 1 Switch GUIGetMsg() Case $GUI_EVENT_CLOSE ExitLoop Case $GUI_EVENT_PRIMARYDOWN MsgBox(0, "", "Should not be shown ;)") EndSwitch WEnd _MouseSetOnEvent($MOUSE_PRIMARYDOWN_EVENT) ;_MouseSetOnEvent($MOUSE_SECONDARYUP_EVENT) EndFunc Func _MouseWheel_Events($iEvent) Switch $iEvent Case $MOUSE_WHEELSCROLLDOWN_EVENT ToolTip("Wheel Mouse Button (scrolling) DOWN Blocked") Case $MOUSE_WHEELSCROLLUP_EVENT ToolTip("Wheel Mouse Button (scrolling) UP Blocked") EndSwitch Return $MOE_BLOCKDEFPROC ;Block EndFunc Func _MousePrimaryDown_Event() ToolTip("Primary Mouse Button Down Blocked") Return $MOE_BLOCKDEFPROC ;Block EndFunc Func _MouseSecondaryUp_Event() ToolTip("Secondary Mouse Button Up Blocked") EndFunc Func _Quit() Exit EndFunc

      Hello ,
      I am trying to fetch data and control a Windows Program.
      The data isn't reflected in the Au3Info tool , hence used SimpleSpy UIA , for trying.
      The code is able to fetch only one row at a time.
      Most Strangely , the code doesn't retreive the same specified row consistently.
      If I run the same code , under same circumstance , it is still fetching different rows.
      This was when op2 and op3 were zero. I would not like to use this at all.

      Also , it takes 3 seconds for it search down the hiearchy and reach the row.
      I will need to fetch ALL the rows continuously for 6 hours every second , in a minimized state.
      Can you please help.
      Attached :
      1. AuInfo summary
      2. Code
      3. Simple Spy Summary
      The Actions I am trying to do (in a Minimzed State - not affecting usage of computer for other purposes)
      1. Fetch all Rows (number of rows will not always be constant
      2. Press the Check box for a specific row(s)
      3. Press the squareOff button on top
      Thanks a lot

      As my first stab at GUI scripting, I'm trying to write a simple graphical interface for Grep for Windows. I have a basic GUI, but I'm stuck on one point and nothing I've tried so far works. The sticking point is that while the Tab key works to move focus from one input control to the next, clicking the mouse on any but the first input does nothing. This seems like a basic feature of GUI functionality that should work out of the box (like Tab), but clearly I'm missing something. I tried (among many other things) Melba23's technique in the post below, but this doesn't do what I'm after -- getting the left click to set the insertion point for user input. Would greatly appreciate a pointer or two. 😉
      Here's my code so far:
