为什么CreateProcess后不成功

Question

我在学习CreateProcess：
为什么执行后fRet=0呢
void Dlg::OnButton1() 
{
PROCESS_INFORMATION pi;
STARTUPINFO si;
si.cb=sizeof(si);
si.wShowWindow=SW_SHOW;
BOOL fRet=CreateProcess(NULL,   "c:\\winnt\\notepad.exe c:\\1.txt",
                  NULL,
                  NULL,
                  FALSE,
                  NORMAL_PRIORITY_CLASS|CREATE_NEW_CONSOLE,
                  NULL,
                  NULL,
                  &si,
                  &pi);
}

Answer 2

PROCESS_INFORMATION pi;
STARTUPINFO si;

memset(&si, 0, sizeof(si));  // add this line
si.cb=sizeof(si);
si.wShowWindow=SW_SHOW; BOOL fRet=CreateProcess(NULL, "c:\\winnt\\notepad.exe c:\\1.txt",
                 NULL,
                 NULL,
                 FALSE,
                 NORMAL_PRIORITY_CLASS|CREATE_NEW_CONSOLE,
                 NULL,
                 NULL,
                 &si,
                 &pi);
