QUESTION 2: Why _GUIScrollBars_GetScrollInfo[2].au3 uses: .... GUICtrlSetResizing($h_GUIC, $GUI_DOCKALL) .... GUICtrlSetResizing($h_GUIC2, $GUI_DOCKALL) .... I mean: Why was a window handle used instead of a control element?

QUESTION 1: What _GUIScrollBars_GetScrollInfo.au3 examples really does? Maybe it is broken or just stopped to work with Win11 EDIT: please note that _GUIScrollBars_GetScrollInfo.au3 is example for _GUIScrollBars_ScrollWindow() My point is that looking on this description I expected there to be an example of scrolling through the window's contents. And bam! It doesn't work as I expected. That's why I'm asking: What _GUIScrollBars_GetScrollInfo.au3 examples really does?

Oops not here.. Moved here:

Aha

I think you can add this stuff to yours GITHUB project.

ufff.. _GUICtrlEdit_SetLimitText($__g_idEdt_Report_Debug, 1024*1024)

Thank you very much. I will have few questions. 1. Is this following part not required when the source and destination size will be the same ? ; Use HALFTONE for better quality when stretching/scaling during capture _WinAPI_SetStretchBltMode($hDC_Capture, $HALFTONE) 2. Why after using: Local Const $hObjectOld = _WinAPI_SelectObject($hMemDC, $hHBmp) there is a need to use it as a kind of revert _WinAPI_SelectObject($hMemDC, $hObjectOld) I understand it's about restoring/freeing/wiping, but reverting seems a bit odd to me. 3. about the cropping feature ; Optionally crop the bitmap to the visible window area, excluding shadow/frame margins If $bCrop Then Local $iLeft, $iTop, $iRight, $iBottom, $pX, $pY #forceref $pX, $pY ; Query the actual visible frame bounds via DWM to get the exact shadow margins Local $tRECT = _WinAPI_DwmGetWindowAttribute($hWnd, $DWMWA_EXTENDED_FRAME_BOUNDS) ; Calculate the margin on each side $iLeft = $tRECT.left - $aWinSize[0] $iTop = $tRECT.top - $aWinSize[1] $iRight = $aWinSize[0] + $aWinSize[2] - $tRECT.right $iBottom = $aWinSize[1] + $aWinSize[3] - $tRECT.bottom Local $hBitmap_Cropped = _GDIPlus_BitmapCloneArea($hBitmap, $iLeft, $iTop, $aWinSize[2] - $iLeft - $iRight, $aWinSize[3] - $iTop - $iBottom) _GDIPlus_BitmapDispose($hBitmap) $hBitmap = $hBitmap_Cropped EndIf If I have a window that contains an embedded IE control, WebView, DebenuViewer, or even simpler _WinAPI_CreateWindowEx(), that is, not the window created using GuiCreate() Then ... was it a case that the cropping is not needed ? I mean when will this be the case when user should to crop entire window ? btw. Question 1 and 3 are quite similar or even the same case.

@UEZ Would you be so kind as to take a look at this code, perhaps improve it or add comments? Perhaps this will allow us to create a better example or improve the HelpFile. Anyway, thanks.

_WinAPI_BitBlt HelpFile description for $iROP: do all these bold text fragments refer to: $hDestDC ?

btw.

It's almost like me Maybe the GDI master could answer... let's see if @UEZ knows the answers ?

yeap btw. Why _WinAPI_BitBlt() was used - and in my scenario it is not needed ?

In relation to: @argumentum and @Nine could you be so nice and check mine modification from: https://github.com/ioa747/NetWebView2Lib/pull/104/changes Func __NetWebView2_freezer($oWebV2M, ByRef $idPic) Local $hWindow_WebView2 = WinGetHandle($oWebV2M.BrowserWindowHandle) #Region ; if $idPic is given then it means you already have it and want to delete it - unfreeze - show WebView2 content If $idPic Then WinSetState($hWindow_WebView2, '', @SW_SHOW) GUICtrlDelete($idPic) $idPic = 0 Return EndIf #EndRegion ; if $idPic is given then it means you already have it and want to delete it - unfreeze - show WebView2 content #Region ; freeze $hWindow_WebView2 #Region ; add PIC to parent window Local $hWindow_Parent = WinGetHandle($oWebV2M.ParentWindowHandle) Local $aPos = WinGetPos($hWindow_WebView2) Local $hPrev = GUISwitch($hWindow_Parent) $idPic = GUICtrlCreatePic('', 0, 0, $aPos[2], $aPos[3]) Local $hPic = GUICtrlGetHandle($idPic) GUISwitch($hPrev) #EndRegion ; add PIC to parent window Local $hPictureDC = _WinAPI_GetDC($hPic) ; Create Dest bitmap Local $hDestination_DC = _WinAPI_CreateCompatibleDC($hPictureDC) ; Creates a memory device context compatible with the specified device Local $hDestination_Bitmap = _WinAPI_CreateCompatibleBitmap($hPictureDC, $aPos[2], $aPos[3]) ; Creates a bitmap compatible with the specified device context Local $hDestination_Sv = _WinAPI_SelectObject($hDestination_DC, $hDestination_Bitmap) ; Selects an object into the specified device context _WinAPI_PrintWindow($hWindow_WebView2, $hDestination_DC, 2) _WinAPI_ReleaseDC($hPic, $hPictureDC) _WinAPI_SelectObject($hDestination_DC, $hDestination_Sv) _WinAPI_DeleteDC($hDestination_DC) ; Set bitmap to control _SendMessage($hPic, $STM_SETIMAGE, 0, $hDestination_Bitmap) _WinAPI_DeleteObject($hDestination_Bitmap) WinSetState($hWindow_WebView2, '', @SW_HIDE) Return $idPic #EndRegion ; freeze $hWindow_WebView2 EndFunc ;==>__NetWebView2_freezer I reduced the code by 11 lines.
