请教这两个类的用法(TStartupInfo、TProcessInformation )

Question

请问这两个类的作用是什么。不知道为什么在帮助里没有这介绍。

Answer 1

var
  StartInfo: STARTUPINFO ; // name structure
  ProcInfo: PROCESS_INFORMATION ; // name structure
begin
    fillchar(ProcInfo, sizeof(ProcInfo), 0); // Set up memory block
    fillchar(StartInfo, sizeof(StartInfo), 0); // Set up memory block
    StartInfo.cb := sizeof(StartInfo); // Set structure size
    if Not CreateProcess( Nil,
                          'Notepad.exe "新建文件.txt"',
                          Nil,
                          Nil,
                          False,
                          0,
                          Nil,
                          PChar(ExtractFilePath(Application.ExeName)),
                          StartInfo,
                          ProcInfo) then
      Exit;    WaitForSingleObject(ProcInfo.hProcess, INFINITE);
    CloseHandle(ProcInfo.hThread);
    CloseHandle(ProcInfo.hProcess);
end;

TStartupInfo参考MSDN
TProcessInformation参考MSDN

Answer 3

这两个不是DELPHI上的类吗。MSDN怎么会有。
