使用AllocConsole()添加调试用控制台

OS:WIN32

1. 

   #include "stdafx.h"
   #include "stdio.h"
   HINSTANCE g_hInstance = 0;
   HANDLE g_hOutput = 0;
   void OnKeyDown( HWND hWnd, WPARAM wParam )
   {

   }
   //窗口处理函数
   LRESULT CALLBACK WndProc( HWND hWnd, UINT nMsg,
                            WPARAM wParam, LPARAM lParam )

       wce.style = CS_HREDRAW | CS_VREDRAW;
       ATOM nAtom = RegisterClassEx( &wce );
       if( nAtom == 0 )
           return FALSE;
       return TRUE;
   }
   //创建主窗口
   HWND CreateMain( LPSTR lpClassName, LPSTR lpWndName )
   {
       HWND hWnd = CreateWindowEx( 0, lpClassName, lpWndName,
                       WS_OVERLAPPEDWINDOW, CW_USEDEFAULT,
                       CW_USEDEFAULT, CW_USEDEFAULT, 
                       CW_USEDEFAULT, NULL, NULL, g_hInstance,
                       NULL );
       return hWnd;
   }
   //显示窗口
   void Display( HWND hWnd )
   {
       ShowWindow( hWnd, SW_SHOW );
       UpdateWindow( hWnd );
   }
   //消息循环
   void Message( )
   {
       MSG nMsg = { 0 };
       while( GetMessage( &nMsg, NULL, 0, 0 ) )
       {
           TranslateMessage( &nMsg );
           DispatchMessage( &nMsg );
       }
   }
   int APIENTRY WinMain(HINSTANCE hInstance,
                        HINSTANCE hPrevInstance,
                        LPSTR     lpCmdLine,
                        int       nCmdShow)
   {
       AllocConsole( );
       g_hOutput = GetStdHandle( STD_OUTPUT_HANDLE );
       g_hInstance = hInstance;
       if( !Register( "Main", WndProc ) )
       {
           MessageBox( NULL, "注册失败", "Infor", MB_OK );
           return 0;
       }
       HWND hWnd = CreateMain( "Main", "window" );
       Display( hWnd );
       Message( );
       return 0;
   }

   

    

 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);
