CreateProcess执行错误,为何?

Question

void CNfServDlg::OnButton1() 
{
// TODO: Add your control notification handler code here
STARTUPINFO  stinfo;
PROCESS_INFORMATION procinfo;
if(! CreateProcess(NULL,"calc.exe",NULL,NULL,FALSE,NORMAL_PRIORITY_CLASS,NULL,NULL,&stinfo,&procinfo))
AfxMessageBox("rar fail");
}

Answer 1

GetLastError(); 然后用Visual C++ 错误查找 查找错误原因

Answer 2

数据没有初始化         STARTUPINFO info;
PROCESS_INFORMATION process;

         memset(&info,0,sizeof(STARTUPINFO));
info.cb=sizeof(info);
info.dwFlags=STARTF_USESHOWWINDOW;
info.wShowWindow=SW_SHOWNORMAL;
::CreateProcess(NULL,ExeFile,NULL,NULL,FALSE,0,NULL,NULL,&info,&process);
