I know this is not the answer you are looking for, but I once tried to delve into the depths of programming GUI appearance, I found that the issue is much more complex than I expected. The solution however may be very simple (for a controlled environment, at least).
 
In general, an application can be written to detect DPI settings and draw its GUI accordingly. Some modern applications (e.g. Microsoft Office 2007) are written from scratch to do that; but most applications, and legacy applications in specific, require practically a complete re-write.
 
Fortunately, Microsoft acknowledge that this would be a trouble for developers, so since Windows Vista, a feature called “DPI Virtualization” is introduced. This feature detects when an application GUI is not fit to high DPI, and draws the GUI to fit. This is done by the operating system, and the application itself does not need to be aware of this. This is a decent solution for legacy applications, until a newer version is written to be DPI-aware and can do it on its own. This is not a perfect solution; DPI-virtualized GUI may appear blurry.
 
By default, DPI virtualization is not enabled (until Windows 8.1, where it is enabled and cannot be easily disabled…). To enable it and use it properly, follow these steps:
 
Step 1: enable DPI Virtualization system-wide:
 
Go to: “Control Panel” “Display” “Set custom text size (DPI)”
Uncheck the checkbox “Use Windows XP style DPI scaling”.
 
post-47848-0-48421300-1403720806_thumb.p
 
This requires log-off/log-on to apply.
 
Step 2: launch your application to see that this indeed solves the issue.
 
Step 3: check impact on other application:
 
Some applications may not react well to DPI Virtualization. For example, I was surprised to see that the modern browser Safari is impacted. Fortunately, You can disable DPI Virtualization per application.
 
(Unfortunately, you cannot enable DPI Virtualization per application; you must enable DPI Virtualization system-wide and then disable DPI Virtualization per application.)
 
To disable DPI Virtualization per application: right-click the application, select “Properties”, switch to the “Compatibility” tab, and check the checkbox “Disable display scaling on high DPI settings”.
 
post-47848-0-70108900-1403720863_thumb.p
 
Note that you can disable DPI Virtualization per application for you only (current user) or for all users.

Thanks for such a comprehensive lecture on the subject.

btw.
Reading your lecture, I noticed that I did not need nor right to wonder about its meaning, at the same time I read it smoothly without pausing, and text virtually alone I explained in my head, which means that both my English skills in reading and understanding is greatly improved by the last two years, and this means both that your lecture was written in friendly style.

Cheers

      Hello,
      Do you have any idea to resize Vector graphic using some maths trick?
      It's example to create Vector image 10x10px and write A
      Local $a10x10 = [ _ 1,1,1,1,1,1,1,1,1,1, _ 1,1,1,0,0,0,0,1,1,1, _ 1,1,0,0,1,1,0,0,1,1, _ 1,1,0,1,1,1,1,0,1,1, _ 1,1,0,1,1,1,1,0,1,1, _ 1,1,0,0,0,0,0,0,1,1, _ 1,1,0,1,1,1,1,0,1,1, _ 1,1,0,1,1,1,1,0,1,1, _ 1,0,0,0,1,1,0,0,0,1, _ 1,1,1,1,1,1,1,1,1,1 _ ] Local $oVector = ObjCreate("WIA.Vector.1") If Not IsObj($oVector) Then ConsoleWrite("+++ Error " & @error & " durning create a Vector.object." & @CRLF) Exit EndIf Local $iBlue = 0xFF0000FF ; ARGB color Local $iWhite = 0xFFFFFFFF ; adding pixels to vector For $i = 0 To UBound($a10x10) - 1 Local $iPixel = $a10x10[$i] Local $iColor = $iBlue If $iPixel = 0 Then $iColor = $iWhite $oVector.Add($iColor) Next ; create a img 10x10 px Local $oImg = $oVector.ImageFile(10, 10) ; path to file Local $sPath = @ScriptDir & "\Vector.bmp" ; delete previous file if exits. FileDelete($sPath) ; save img to script direction. $oImg.SaveFile($sPath) ; show result, you have to use 800% size to see effects. ShellExecute("Vector.bmp")

      Hello dears,
      I'm trying to write a script in AutoIT but, I have issue in DPI. I'm basically a Lead Software Developer and I use AutoIT from time to time. I have an ERP Launcher that should work on all machines starting by Windows 7, Windows 8.x , Windows 10, Windows Server 2003/2008/2012.
      When I was searching in AutoIT forum, I could see previously this " Writing DPI Awareness App - workaround" in the signature of Mr. @mLipok,, but clicking on the link, => page not found.
      Do you have any new link or something that you can share with me ? I'm using macbook pro with retina display and VMware machines: Windows 10 and Server 2012 as development machines, but both of them they have 200% scaling and they have AutoIT installed. In this case, when I use Koda (blurry font for sure), I have the controls as I want, and application is working fine, but also blurry font, until it is used on 96 DPI machine.
      Now, in windows 10, with DPI System Enhanced feature in the compatibility tab, the application running on 200% scaling is excellent visual like it's running on 96 DPI without touching my code and without doing anything, but no all clients they have windows 10. It seems Microsoft worked a lot on the new feature. But for other machines like windows 7/8/2012, the font is blurry if the clients have scaling above 100% (more than 96 DPI). I know how to enable hidpi stuff in the wrapper and I know how to write the code to use a scaling factor that can be multiplied by every coordinate, but this way is cumbersome and I have to change all coordinates of all X, Y, Width, Height after getting the code from Koda. Is there a fast way ? 
      So, what do you recommend me guys ?
      Thanks,
      Jowy

      Hi all,
      I have simple question and can not find answer on it. I am working with WPF application and I want to automate it with Autoit. For now I found Inspect.exe tool which gives me all wpf controls, but how do I can use that controls to click some buttons or dropdown list?
      For example I have such a controls
      AutomationId:    "comboArrayType" or 
      Name:    "_Submit"
      Which autoit command can I use to handle this?
      Thanks and Regards, Roman Y

      Been struggling with this one for a while. 
      when I do a _screencapture_capture call on a high resolution monitor (like my surface book) it gives me an image that has 2 problems:
      1. its in the wrong location on the screen
      and
      2. it gives me a picture that is larger than the area of the screen I selected, though it only has the content of what I selected. 
      ---------------------------
      I was able to easily fix problem #1 by manually adjusting the x y coordinates to compensate for the amount of DPI scale I have.
      for instance if I'm 200% zoomed in the code looks like this:
      Local $bmp = _ScreenCapture_Capture("", $iX1*2, $iY1*2, $iX2*2, $iY2*2, false)  it's problem #2 that is the big problem. I'd like to attach a screen shot of what I'm talking about (see capture.png)

      ---------------------------
      Now I basically understand why this is happening. ScreenCapture grabs each pixel of the screen. This screen, being a high resolution, when its zoomed in adds up several pixels to make one on the screen. 
      This is a problem for me because I'm taking images of the screen and later looking for those exact images on the screen. if everything is blown up by an indeterminate amount (in my case 2x) then those images can't be found later on. 
      Does anyone know what I can do? 
      I tried resizing the images back down to no avail. 
      _GDIPlus_ImageResize and _GDIPlus_ImageScale don't work because they don't compress the pixels correctly. quality is lost. and the exact image isn't preserved, so I can't search for it later. (see capture1.png)

       
      Anyway, I'm about to give up, been on this problem for too long! does anyone know what I can do? Seems to me that the ideal solution would be to eventually have autoit add an argument to _screencapture_capture that lets you specify a DPI scale amount or something.  that can be pulled from the registry at HKEY_CURRENT_USER\control panel\desktop\windowmetrics\appliedDPI.
      But in the meantime, does anyone have any suggestions for how I can make my program compatible with 4k resolution monitors? I either need to take the screen capture like normal, then scale it down appropriately without losing quality, or I need to capture the screen in the first place like the human sees it. But I don't know how to do that either. 
      I'll post my relevant code here: (in my project I call ScreenCapture_DPI_Aware)
      #include <Security.au3> Func _GetAppliedDPI()   Local $aArrayOfData = _Security__LookupAccountName(@UserName)   If IsArray($aArrayOfData) Then   ;msgbox(64, "SID String = ", $aArrayOfData[0] & @CRLF)   ;msgbox(64, "Domain name = ", $aArrayOfData[1] & @CRLF)   ;msgbox(64, "SID type = ", _Security__SidTypeStr($aArrayOfData[2]) & @CRLF)     ;Local $AppliedDPI = RegRead("HKEY_USERS\" & $aArrayOfData[0] & "\Control Panel\Desktop\WindowMetrics", "AppliedDPI") Local $AppliedDPI = RegRead("HKEY_CURRENT_USER\Control Panel\Desktop\WindowMetrics", "AppliedDPI")     return $AppliedDPI   EndIf EndFunc Func GetScale()   $applied = _GetAppliedDPI()   if $applied == "" then     return 1   else     return $applied / 96   EndIf EndFunc Func ScreenCapture_Capture_DPI_Aware($sBMP_Path, $iX1, $iY1, $iX2, $iY2, $bool)   $R = GetScale() ;Raito   Local $bmp = _ScreenCapture_Capture($sBMP_Path, $iX1*$R, $iY1*$R, $iX2*$R, $iY2*$R, $bool) ;Scaling didn't work: ;_ScaleImage($bmp, $sBMP_Path, abs($iX2 - $iX1), abs($iY2 - $iY1), $R)   ;return _ScreenCapture_Capture($sBMP_Path, $iX1*$R, $iY1*$R, $iX2*$R, $iY2*$R, $bool) EndFunc ;Func _ScaleImage($bmp, $outimage, $w, $h, $scale) ; _GDIPlus_Startup() ;Get the encoder of to save the resized image in the format you want. ; Local $Ext = StringUpper(StringMid($outimage, StringInStr($outimage, ".", 0, -1) + 1)) ; $CLSID = _GDIPlus_EncodersGetCLSID($Ext) ; code found here : https://www.autoitscript.com/autoit3/docs/libfunctions/_GDIPlus_ImageSaveToStream.htm ; Local $sImgCLSID = _GDIPlus_EncodersGetCLSID("png") ;create CLSID for a JPG image file type ; Local $tGUID = _WinAPI_GUIDFromString($sImgCLSID) ;convert CLSID GUID to binary form and returns $tagGUID structure ; Local $tParams = _GDIPlus_ParamInit(1) ;initialize an encoder parameter list and return $tagGDIPENCODERPARAMS structure ; Local $tData = DllStructCreate("int Quality") ;create struct to set JPG quality setting ; DllStructSetData($tData, "Quality", 100) ;quality 0-100 (0: lowest, 100: highest) ; Local $pData = DllStructGetPtr($tData) ;get pointer from quality struct ; _GDIPlus_ParamAdd($tParams, $GDIP_EPGQUALITY, 1, $GDIP_EPTLONG, $pData) ;add a value to an encoder parameter list ; Local $gbmp = _GDIPlus_BitmapCreateFromHBITMAP($bmp) ; _WinAPI_DeleteObject($bmp) ; Local $gsbmp = _GDIPlus_ImageResize($gbmp, $w * $scale, $h * $scale) ;Local $ext = _GDIPlus_EncodersGetCLSID("PNG") ; _GDIPlus_ImageSaveToFileEx($gsbmp, $outimage, $sImgCLSID) ; _GDIPlus_BitmapDispose($gbmp) ; _GDIPlus_BitmapDispose($gsbmp) ; _GDIPlus_Shutdown() ;EndFunc

      In my code, I'm using GUICtrlCreateLabel to create a label and GUICtrlSetFont to set the font. Example...
      $SELlbl = GUICtrlCreateLabel("Hello World", 8, 8, 286, 24) GUICtrlSetFont(-1, 12, 800, 0, "MS Sans Serif") This works in my GUI unless display settings are changed in Windows 7 from 100% to 125-150%. Then the text is blown up and is misaligned with my GUI. 
      Is there a simple way to ignore the display setting and force the font size?
