使用AllocConsole()添加調試用控制台

AllocConsole 函數

為調用進程分配一個新的控制台。

　　使用步驟：

　　1.　　AllocConsole();　　　　//分配控制台

　　2.　　HANDLE  g_hOutput=GetStdHandle( STD_OUTPUT_HANDLE );　　　　//獲取標准輸出設備句柄

　　3.　　WriteConsole(g_hOupput,lpBuffer,lpNumberofcharswritten,lpReserved);　　　　　　　//寫入字符串到控制台緩沖區

 

代碼演示：

OS:WIN32

在vc 6.0中建一個空的win32項目，把代碼復制進去進行。

 附帶控制台的一些函數：

HANDLE hOut = GetStdHandle(STD_OUTPUT_HANDLE); 
	// 獲取標准輸出設備句柄 
	CONSOLE_SCREEN_BUFFER_INFO bInfo; // 窗口緩沖區信息 
	GetConsoleScreenBufferInfo(hOut, & bInfo ); 
	// 獲取窗口緩沖區信息 
	char strTitle[255]; 
	GetConsoleTitle(strTitle, 255); // 獲取窗口標題 
	//printf("當前窗口標題是：%s\n", strTitle); 
	//_getch(); 
	SetConsoleTitle("變形實驗"); // 獲取窗口標題 
	//_getch(); 
	COORD size = {1024, 1024}; 
	SetConsoleScreenBufferSize(hOut,size); // 重新設置緩沖區大小 
	//_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);
