Google-chrome – Make Chrome open on second monitor

delphidelphi-xe5google-chrome

I'm currently trying to make an app that forces a Chrome window to open on my second monitor but I can't find anyway to do it using arguments, now I'm wondering if I can somehow use Delphi to force it to open on the second screen or a specific pixel? This is solely an app for myself and my PC so I can put the code in specific for my case.

I'm currently using this bit of code to start the app

procedure TForm1.BtnClick(Sender: TObject);
begin
 ExecProcess(ChromePath,'',False);
end;

function ExecProcess(ProgramName, WorkDir: string; Wait: boolean): integer;
var
  StartInfo: TStartupInfo;
  ProcInfo: TProcessInformation;
  CreateOK: boolean;
  ExitCode: integer;
  dwExitCode: DWORD;
begin
  ExitCode := -1;

  FillChar(StartInfo, SizeOf(TStartupInfo), #0);
  FillChar(ProcInfo, SizeOf(TProcessInformation), #0);
  StartInfo.cb := SizeOf(TStartupInfo);

  if WorkDir <> '' then
  begin
    CreateOK := CreateProcess(nil, Addr(ProgramName[1]), nil, Addr(WorkDir[1]),
      false, CREATE_NEW_PROCESS_GROUP + NORMAL_PRIORITY_CLASS, nil, nil,
      StartInfo, ProcInfo);
  end
  else
  begin
    CreateOK := CreateProcess(nil, Addr(ProgramName[1]), nil, nil, false,
      CREATE_NEW_PROCESS_GROUP + NORMAL_PRIORITY_CLASS, nil, Addr(WorkDir[1]),
      StartInfo, ProcInfo);
  end;

  { check to see if successful }

  if CreateOK then
  begin
    // may or may not be needed. Usually wait for child processes
    if Wait then
    begin
      WaitForSingleObject(ProcInfo.hProcess, INFINITE);
      GetExitCodeProcess(ProcInfo.hProcess, dwExitCode);
      ExitCode := dwExitCode;
    end;
  end
  else
  begin
    ShowMessage('Unable to run ' + ProgramName);
  end;

  CloseHandle(ProcInfo.hProcess);
  CloseHandle(ProcInfo.hThread);

  Result := ExitCode;

end;

Can I somehow use something in StartInfo.wShowWindow maybe?

Best Solution

Chrome allows you to pass a position and size on the command line with --window-position and --window-size I believe. Check out this page for details.

Example:

:: Left screen is 1024x768
"C:\chrome.exe" "https://www.example.com/?a=0&b=1" --window-position=0,0  --window-size=1024,768 --user-data-dir="C:\my-chrome1"

:: Right screen is 1280x720
:: Now chrome.exe we need to open in the second screen then we do it as below:
:: we might want to use --kiosk but combination of --kiosk and --window-position wont work so in that case we can use --app


"C:\chrome.exe" --app="https://www.example.com/?a=0&b=1" --window-position=1025,0 --window-size=1280,720 --user-data-dir="C:\my-chrome2"
