CreateProcess示例 - 注意si的初始化和buffer

作者：半瓶墨水链接：http://www.2maomao.com/blog/createprocess-sample-usage/

void Helper::StartApp(wstring cmd)
{
   TCHAR buff[10000] = { 0 };
   _tcscpy(buff, cmd.c_str());

   PROCESS_INFORMATION pi;
   STARTUPINFO si = {0};
   si.cb = sizeof(STARTUPINFO);

   // Create the child process.
   BOOL bRtn = CreateProcess(
   NULL,
   buff,
   NULL, // process security attributes
   NULL, // primary thread security attributes
   TRUE, // handles are inherited
   0, // creation flags
   NULL, // use parent's environment
   NULL, // use parent's current directory
   &si, // STARTUPINFO pointer
   &pi); // receives PROCESS_INFORMATION

   if (!bRtn)
   {
   MessageBox(NULL, buff,
   L"CreateProcess failed!", MB_ICONERROR | MB_OK);
   }
}

试了很久，加了下面两段就没问题了：
1.
TCHAR buff[10000] = { 0 }; _tcscpy(buff, cmd.c_str());

2.
STARTUPINFO si = {0}; si.cb = sizeof(STARTUPINFO);
