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
