typedef LONG (WINAPI *PROCNTQSIP)(HANDLE, UINT, PVOID, ULONG, PULONG);

在CWinApp::InitInstance()中添加：
NtQueryInformationProcess = (PROCNTQSIP)GetProcAddress(GetModuleHandle(L"ntdll.dll"),
"NtQueryInformationProcess");
HANDLE hProcess;
PROCESS_BASIC_INFORMATION pbi;
hProcess = OpenProcess(PROCESS_QUERY_INFORMATION,FALSE,GetCurrentProcessId());
NtQueryInformationProcess(hProcess, ProcessBasicInformation, (PVOID)&pbi,
sizeof(PROCESS_BASIC_INFORMATION), NULL);
CloseHandle(hProcess);
AttachConsole(pbi.InheritedFromUniqueProcessId);
freopen("CONOUT$","w",stdout); // 重定向输出
用printf函数就可以把信息输出到启运它的那个CMD窗口了。
在cmd启动一个win32程序,printf把信息输出到启运它的那个CMD窗口
