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

#define ProcessBasicInformation 0  
typedef struct  
{  
	DWORD ExitStatus;  
	DWORD PebBaseAddress;  
	DWORD AffinityMask;  
	DWORD BasePriority;  
	ULONG UniqueProcessId;  
	ULONG InheritedFromUniqueProcessId;  
}   PROCESS_BASIC_INFORMATION;  
typedef LONG (WINAPI *PROCNTQSIP)(HANDLE, UINT, PVOID, ULONG, PULONG);  
PROCNTQSIP NtQueryInformationProcess; 

　　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。

方法二：

AttachConsole(ATTACH_PARENT_PROCESS); // 将当前程序附着到父进程上，因为是从控制台启动的，所以当前程序的父进程就是那个控制台。 
	freopen("CONIN$", "r+t", stdin); // 重定向 STDIN 
	freopen("CONOUT$", "w+t", stdout); // 重定向STDOUT
