windows - CreateProcess hook to add CommandLine -

-

i have project adding specific flags (command lines) chrome browser, problem doing creating new chrome shortcut, flags want execute.

in last days solution became superficial, , requested more 'deeper'. looking on windows registry, didn't found solution always add flags when run chrome, started thinking hook createprocess explorer, , check if process run chrome, add flags in lpcommandline attribute.

i know hook explorer pretty 'intrusive' solution, became helpful because have other achieves putting off on project, , hooking me them done.

i got hook working, tried many ways add command lines when chrome found, no success... right (and tried @ least 8 different solutions) detour function is:

function interceptcreateprocess(lpapplicationname: pchar;             lpcommandline: pchar;             lpprocessattributes, lpthreadattributes: psecurityattributes;             binherithandles: bool;             dwcreationflags: dword;             lpenvironment: pointer;             lpcurrentdirectory: pchar;             const lpstartupinfo: startupinfo;             var lpprocessinformation: process_information): bool; stdcall; var   cmd: string; begin   result:= createprocessnext(lpapplicationname,           lpcommandline,           lpprocessattributes,           lpthreadattributes,           binherithandles,           dwcreationflags,           lpenvironment,           lpcurrentdirectory,           lpstartupinfo,           lpprocessinformation);   if (pos(chrome, uppercase(string(lpapplicationname))) > 0)   begin     cmd:= ' --show-fps-counter';     lpcommandline:= pchar(widestring(lpcommandline + cmd));     showmessage(lpcommandline);   end; end;

the "--show-fps-counter" command line i'm trying add without success.

my delphi version xe4.

ok, pretty obvious thing... need add parameter before calling createprocessnext (original function)! so, doing:

 if (pos(chrome, uppercase(string(lpapplicationname))) > 0)   begin     lpcommandline:= pchar(lpcommandline + ' --show-fps-counter');   end;   result:= createprocessnext(lpapplicationname,           lpcommandline,           lpprocessattributes,           lpthreadattributes,           binherithandles,           dwcreationflags,           lpenvironment,           lpcurrentdirectory,           lpstartupinfo,           lpprocessinformation);

works... note inverted order change lpcommandline. thank's participants , i'll still consider said here.
