Sometimes you wish you could just execute a program in the searchpath and wait for it to finish. This function will do that
Code:

function LaunchCommandAndWait(command)
  local lpStartupInfo=createMemoryStream()
  local lpProcessInfo=createMemoryStream()
  local sisize
  local pisize
  local r

  local result

  if cheatEngineIs64Bit() then
    sisize=104
    pisize=24
  else
    sisize=68
    pisize=16
  end
  lpStartupInfo.writeDword(sisize)
  lpStartupInfo.Size=sisize
  lpProcessInfo.Size=pisize

  r=executeCodeLocalEx('CreateProcessA',0,command,0,0,0,0,0,0,lpStartupInfo.Memory,lpProcessInfo.Memory);

  if r~=0 then
    lpProcessInfo.Position=0
    local hProcess
    local hThread
    if cheatEngineIs64Bit() then
      hProcess=lpProcessInfo.readQword()
      hThread=lpProcessInfo.readQword()
    else
      hProcess=lpProcessInfo.readDword()
      hThread=lpProcessInfo.readDword()
    end

    r=executeCodeLocalEx('WaitForSingleObject', hProcess, 0xffffffff)
    local ExitCode=createMemoryStream()
    ExitCode.Size=4
    if executeCodeLocalEx('GetExitCodeProcess', hProcess, ExitCode.Memory)~=0 then
      result=ExitCode.readDword()
    end
    ExitCode.destroy()

    --cleanup handles
    executeCodeLocalEx('CloseHandle', hProcess)
    executeCodeLocalEx('CloseHandle', hThread)
  end

  lpProcessInfo.destroy()
  lpStartupInfo.destroy()

  return result
end


e.g:
LaunchCommandAndWait('notepad.exe d:\\bla.txt')

Just a fallback;

The code opens the file at the given path.
But when the file is opened, CE becomes intuitive and out of use, has difficulty working.
CE returns to normal when I close the file.
For CE 7.4 and Windows 10 it responded differently in my case.

Is it normal for the code to disable the CE until the file is closed?

it's recommended to run it from a thread
