Is there a way to color it? Like the grey/black of the notification area?
The notification area has a slight blur as well and it would be nice if you were able to build applications like this .. :)

It seems that you have to use GDI+ or other stuff to color it.

Here I enabled the blur-behind on a layered window and drawn a partly transparent rectangle and some stuff on top.

Yeah that's the way I've done it too. I created a layered GUI and set the background layer with the blur style and I colored the layer in front using a transparent PNG as background. This works fine :)

Friends! People make it so that the blur is applied together with the color. Below are two examples of code:

But there is a problem — you need to manage the size of the curbs. If borders are narrowed or absent in the design, then these parameters must be specified in function _WindowCompozitionAttribute. How to do it - you need to look for documentation ...

      Hi Virtual People, 
      I'm trying to lock my screen in Windows 10 but to no avail. 
      Has Windows 10 forbidden this feature? 
      Send("#l") Above code does not work. Even sending Ctrl Alt Del does not work nor as an Admin. 
      Note: I want to lock my screen, not log off. Thanks for been kind.

      Hi Guys,
       
      I`m trying to record with my webcam in 5s intervalls and do some stuff between starting to record and stoping.
      I took code from here: https://www.autoitscript.com/forum/topic/27925-webcam-example/
      and took what looked relevant to me.
      I use 3 different files:
       Is called WMS.au3 and contains all the constants for the dll calls is called rec.au3 and does all necessary dll calls to start a webcam recording to a file Is called stopcam.exe and does the dll calls to stop recording into a file WMS.au3  :
      $WM_CAP_START = 0x400 $WM_CAP_UNICODE_START = $WM_CAP_START +100 $WM_CAP_PAL_SAVEA = $WM_CAP_START + 81 $WM_CAP_PAL_SAVEW = $WM_CAP_UNICODE_START + 81 $WM_CAP_UNICODE_END = $WM_CAP_PAL_SAVEW $WM_CAP_ABORT = $WM_CAP_START + 69 $WM_CAP_DLG_VIDEOCOMPRESSION = $WM_CAP_START + 46 $WM_CAP_DLG_VIDEODISPLAY = $WM_CAP_START + 43 $WM_CAP_DLG_VIDEOFORMAT = $WM_CAP_START + 41 $WM_CAP_DLG_VIDEOSOURCE = $WM_CAP_START + 42 $WM_CAP_DRIVER_CONNECT = $WM_CAP_START + 10 $WM_CAP_DRIVER_DISCONNECT = $WM_CAP_START + 11 $WM_CAP_DRIVER_GET_CAPS = $WM_CAP_START + 14 $WM_CAP_DRIVER_GET_NAMEA = $WM_CAP_START + 12 $WM_CAP_DRIVER_GET_NAMEW = $WM_CAP_UNICODE_START + 12 $WM_CAP_DRIVER_GET_VERSIONA = $WM_CAP_START + 13 $WM_CAP_DRIVER_GET_VERSIONW = $WM_CAP_UNICODE_START + 13 $WM_CAP_EDIT_COPY = $WM_CAP_START + 30 $WM_CAP_END = $WM_CAP_UNICODE_END $WM_CAP_FILE_ALLOCATE = $WM_CAP_START + 22 $WM_CAP_FILE_GET_CAPTURE_FILEA = $WM_CAP_START + 21 $WM_CAP_FILE_GET_CAPTURE_FILEW = $WM_CAP_UNICODE_START + 21 $WM_CAP_FILE_SAVEASA = $WM_CAP_START + 23 $WM_CAP_FILE_SAVEASW = $WM_CAP_UNICODE_START + 23 $WM_CAP_FILE_SAVEDIBA = $WM_CAP_START + 25 $WM_CAP_FILE_SAVEDIBW = $WM_CAP_UNICODE_START + 25 $WM_CAP_FILE_SET_CAPTURE_FILEA = $WM_CAP_START + 20 $WM_CAP_FILE_SET_CAPTURE_FILEW = $WM_CAP_UNICODE_START + 20 $WM_CAP_FILE_SET_INFOCHUNK = $WM_CAP_START + 24 $WM_CAP_GET_AUDIOFORMAT = $WM_CAP_START + 36 $WM_CAP_GET_CAPSTREAMPTR = $WM_CAP_START + 1 $WM_CAP_GET_MCI_DEVICEA = $WM_CAP_START + 67 $WM_CAP_GET_MCI_DEVICEW = $WM_CAP_UNICODE_START + 67 $WM_CAP_GET_SEQUENCE_SETUP = $WM_CAP_START + 65 $WM_CAP_GET_STATUS = $WM_CAP_START + 54 $WM_CAP_GET_USER_DATA = $WM_CAP_START + 8 $WM_CAP_GET_VIDEOFORMAT = $WM_CAP_START + 44 $WM_CAP_GRAB_FRAME = $WM_CAP_START + 60 $WM_CAP_GRAB_FRAME_NOSTOP = $WM_CAP_START + 61 $WM_CAP_PAL_AUTOCREATE = $WM_CAP_START + 83 $WM_CAP_PAL_MANUALCREATE = $WM_CAP_START + 84 $WM_CAP_PAL_OPENA = $WM_CAP_START + 80 $WM_CAP_PAL_OPENW = $WM_CAP_UNICODE_START + 80 $WM_CAP_PAL_PASTE = $WM_CAP_START + 82 $WM_CAP_SEQUENCE = $WM_CAP_START + 62 $WM_CAP_SEQUENCE_NOFILE = $WM_CAP_START + 63 $WM_CAP_SET_AUDIOFORMAT = $WM_CAP_START + 35 $WM_CAP_SET_CALLBACK_CAPCONTROL = $WM_CAP_START + 85 $WM_CAP_SET_CALLBACK_ERRORA = $WM_CAP_START + 2 $WM_CAP_SET_CALLBACK_ERRORW = $WM_CAP_UNICODE_START + 2 $WM_CAP_SET_CALLBACK_FRAME = $WM_CAP_START + 5 $WM_CAP_SET_CALLBACK_STATUSA = $WM_CAP_START + 3 $WM_CAP_SET_CALLBACK_STATUSW = $WM_CAP_UNICODE_START + 3 $WM_CAP_SET_CALLBACK_VIDEOSTREAM = $WM_CAP_START + 6 $WM_CAP_SET_CALLBACK_WAVESTREAM = $WM_CAP_START + 7 $WM_CAP_SET_CALLBACK_YIELD = $WM_CAP_START + 4 $WM_CAP_SET_MCI_DEVICEA = $WM_CAP_START + 66 $WM_CAP_SET_MCI_DEVICEW = $WM_CAP_UNICODE_START + 66 $WM_CAP_SET_OVERLAY = $WM_CAP_START + 51 $WM_CAP_SET_PREVIEW = $WM_CAP_START + 50 $WM_CAP_SET_PREVIEWRATE = $WM_CAP_START + 52 $WM_CAP_SET_SCALE = $WM_CAP_START + 53 $WM_CAP_SET_SCROLL = $WM_CAP_START + 55 $WM_CAP_SET_SEQUENCE_SETUP = $WM_CAP_START + 64 $WM_CAP_SET_USER_DATA = $WM_CAP_START + 9 $WM_CAP_SET_VIDEOFORMAT = $WM_CAP_START + 45 $WM_CAP_SINGLE_FRAME = $WM_CAP_START + 72 $WM_CAP_SINGLE_FRAME_CLOSE = $WM_CAP_START + 71 $WM_CAP_SINGLE_FRAME_OPEN = $WM_CAP_START + 70 $WM_CAP_STOP = $WM_CAP_START + 68 rec.au3  :

      Unfortunately this is not working as I thought it would be working.
      Does someone see what I´m doing wrong?
      It should record the webcam for about 10 seconds ( a little less) and save that to an .avi file.
      It does not stop the recording , I have to stop the process manually...
      Secondly, which confuses me more is that it creates the test.avi not in the location is specified in the script... its stored in the ScriptDir for whatever reason haha
      I hope you can help me

      I was looking around the help file and I came across _GDIPlus_GraphicsDrawRect and _WinAPI_DrawLine and I seem to be having the same "problem" where every time it draws into a window and you lose or gain focus it has to redraw itself. Is there anyway around this? 
      #include <WindowsConstants.au3> #include <WinAPI.au3> #Include <GDIPlus.au3> _GDIPlus_Startup() Run("notepad.exe") $hWnd = WinWait("Untitled") $hGraphic = _GDIPlus_GraphicsCreateFromHWND($hWnd) $Color = 0xFFFF0000 $hPen = _GDIPlus_PenCreate($Color, 2) For $i = 1 To 10 _GDIPlus_GraphicsDrawRect($hGraphic, 200, 200, 25 ,25, $hPen) ToolTip($i) Sleep(1000) Next _WinAPI_RedrawWindow($hWnd, 0, 0, $RDW_INVALIDATE + $RDW_ALLCHILDREN) _GDIPlus_GraphicsDispose($hGraphic) _GDIPlus_PenDispose($hPen) _GDIPlus_Shutdown()
