it seems incredible but it seems to work, there is a difference between the various interpolations.

So I could start from the Vcl.Direct2D unit to create a unit that uses DirectD2 1.1..mm.. it could be an indea. For now I have done this and it seems to work, but I don't know if I use Direct2D 1.1 at 100% _scale := width / _HostDesktopWidth; IMGpitch:=_HostDesktopWidth*4; if (DesktopFrame=nil) or ( _DesktopFrameRect.right <> _HostDesktopWidth ) or ( _DesktopFrameRect.bottom <> _HostDesktopHeight ) then begin _DesktopFrameRect.left:=0; _DesktopFrameRect.right:=_HostDesktopWidth; _DesktopFrameRect.top:=0; _DesktopFrameRect.bottom:=_HostDesktopHeight; BitmapProp.DpiX := 0; BitmapProp.DpiY := 0; BitmapProp.pixelFormat.Format := DXGI_FORMAT_B8G8R8A8_UNORM; BitmapProp.pixelFormat.AlphaMode := D2D1_ALPHA_MODE_IGNORE; _FD2DCanvas.RenderTarget.CreateBitmap(D2D1SizeU(_HostDesktopWidth, _HostDesktopHeight), _IMGBuffer, IMGpitch, BitmapProp, DesktopFrame); WriteLog('[Paint] CreateBitmap '+intToStr(_HostDesktopWidth)+'x'+intToStr(_HostDesktopHeight) ); end else begin _DesktopFrameRect.left:=0; _DesktopFrameRect.right:=_HostDesktopWidth; _DesktopFrameRect.top:=0; _DesktopFrameRect.bottom:=_HostDesktopHeight; DesktopFrame.CopyFromMemory(_DesktopFrameRect,_IMGBuffer,IMGpitch); end; if _firstRender then begin _ConnectionStartedAt:=GetTickCount; ComputeTransform; _firstRender:=false; end; _FD2DCanvas.RenderTarget.SetTransform(_FTransform); LRect.left:=0; LRect.right:=_HostDesktopWidth; LRect.top:=0; LRect.bottom:=_HostDesktopHeight; (_FD2DCanvas.RenderTarget as ID2D1DeviceContext ).DrawBitmap(DesktopFrame,LRect,1, _InterpolationMode);

I use Delphi Alexandria and when compiling the example projects there are many errors due to missing {$IFDEF FPC} and if I set FPC between the conditional defines there are commands that don't exist in Delphi.

Thanks but It doesn't work on Delphi , it needs many corrections 😞

I have an application that uses a TDirect2DCanvas to render an image stream. However, I noticed that the iterpolation used is only Linear (Direct2D 1.0), but if I wanted to use those introduced with Direct2D 1.1 (bicubic, etc.) i would have to add unit Winapi.D2DMissing. Now the problem is that the TDirect2DCanvas does not use ID2D1DeviceContext (added in Winapi.D2DMissing) as the rendering target but ID2D1RenderTarget. I can't figure out how to use the new Direct2D 1.1 features. Anyone has any ideas?

You're right! Fixed the error now it works 🤩 : procedure TForm1.FormKeyUp(Sender: TObject; var Key: Word; Shift: TShiftState); var buf:WideChar; KSta:TKeyboardState; begin //initialize TKeyboardState GetKeyboardState(ksta); //limit to 1 the capture lenght into buffer that is wide char ToUnicodeEx( key, 0, ksta, @buf, 1, 0, 0); log.Lines.Add('KeyUp : '+ inttoStr(key)+'='+buf ); end; Now if I press "è" it wrote into TMemo: KeyUp : 186=è Thank you all!

I almost found a solution: procedure TForm1.FormKeyUp(Sender: TObject; var Key: Word; Shift: TShiftState); var buf:WideChar; KSta:TKeyboardState; s:string; begin log.Lines.Add('KeyUp : '+ inttoStr(key) ); Winapi.Windows.ToUnicodeEx( key, 0, ksta, @buf,255, 0, 0); s:=WideCharToString(@buf); log.Lines.Add('KeyUp : '+ s); end; Obviously I will not use it like that, but there is a problem, it goes into exception when it writes the result to the log (TMemo). Even if I levo the last line goes into exception, however the variable s is valued.

Because I need to emulate the Keydown and KeyUp events for every single character pressed.

I use VCL and the App isn't made with Delphi. The purpose is to send the KeyUp and KeyDown events with the char from a Delphi-VCL application to a non-delphi application running on Android, iOS and Mac.

Hi everyone, I'm making an application that communicates between different operating systems. In this case I have to send a character when it is pressed from Windows to MAC. In the Form.OnKeyUp function there is the parameter "key: Word" which represents the character code. If it is not a special character (à, è, ì, ò, ù) this co corresponds to the ASCII code. If, on the other hand, I press the "è" key, the code will be 222 which however does not correspond to its ASCII code and therefore I send wrong information to the MAC which is unable to retrieve the corresponding character. How do I get the exact ASCII code of that character? Thank you all.

ok, I understand the situation! Thank you for the valuable insights, now I'll have some fun! : D

There are remote control programs that let you choose which session to open the connection in, how do they do it?

What do you mean? I don't want to bypass the windows login, but I would like to do it through a program controlled by a user who knows their login credentials.

Thanks for the hint, I deepen the subject.👍 Of course it wouldn't be bad if someone had already solved it! After all, the community is also useful for this.. 😋

My application not only has administrator privileges, but runs as a System user.
