使用AllocConsole()添加调试用控制台

AllocConsole 函数

为调用进程分配一个新的控制台。

　　使用步骤：

　　1.　　AllocConsole();　　　　//分配控制台

　　2.　　HANDLE  g_hOutput=GetStdHandle( STD_OUTPUT_HANDLE );　　　　//获取标准输出设备句柄

　　3.　　WriteConsole(g_hOupput,lpBuffer,lpNumberofcharswritten,lpReserved);　　　　　　　//写入字符串到控制台缓冲区

 

代码演示：

OS:WIN32

在vc 6.0中建一个空的win32项目，把代码复制进去进行。

附带控制台的一些函数：

HANDLE hOut = GetStdHandle(STD_OUTPUT_HANDLE); 
	// 获取标准输出设备句柄 
	CONSOLE_SCREEN_BUFFER_INFO bInfo; // 窗口缓冲区信息 
	GetConsoleScreenBufferInfo(hOut, & bInfo ); 
	// 获取窗口缓冲区信息 
	char strTitle[255]; 
	GetConsoleTitle(strTitle, 255); // 获取窗口标题 
	//printf("当前窗口标题是：%s\n", strTitle); 
	//_getch(); 
	SetConsoleTitle("变形实验"); // 获取窗口标题 
	//_getch(); 
	COORD size = {1024, 1024}; 
	SetConsoleScreenBufferSize(hOut,size); // 重新设置缓冲区大小 
	//_getch(); 
	SMALL_RECT rc = {0,0, 1024-1, 1024-1}; // 重置窗口位置和大小 
	SetConsoleWindowInfo(hOut,true ,&rc); 
	COLORREF color = RGB(192,192,192);
	SetConsoleTextAttribute(hOut,FOREGROUND_INTENSITY | FOREGROUND_BLUE);
