MFC中增加输出到控制台

#include <io.h>#include <stdio.h>#include <fcntl.h>void InitConsoleWindow(){    int nCrt = 0;    FILE* fp;    AllocConsole();    nCrt = _open_osfhandle((long)GetStdHandle(STD_OUTPUT_HANDLE), _O_TEXT);    fp = _fdopen(nCrt, "w");    *stdout = *fp;    setvbuf(stdout, NULL, _IONBF, 0);}

在C**App的InitInstance()中添加如下：

BOOL CMFCTempleApp::InitInstance(){    InitConsoleWindow();    printf( "str   =   %s\n ",   "debug");
