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?
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"
