1.    有些MFC的系统类的成员函数不需要对应的ID消息处理，它们响应系统
   内部的消息。例如Doc类的OnOpenDocument()函数。


2.    怎么样在Dialog窗体内部得到Document的指针？
       
3. 位图显示
	//GDI位图显示
    CBitmap bm;
	bm.LoadBitmap(IDB_BITMAP_BACKRND01);

	CDC dcMem;
	dcMem.CreateCompatibleDC(pDC);

    dcMem.SelectObject(&bm);
	
	BITMAP img;
	bm.GetBitmap(&img);
	pDC->BitBlt(0,0,img.bmWidth,img.bmHeight,&dcMem,0,0,SRCCOPY);

分析:
1) MFC类基本的启动流程为： CApp -> CMainFrame ->CDoc ->CChildFrame ->CView
   其中若没有打开文档，则只加载到CMainFrame，打开/新建文档，均加载后三项。


[050329]
1.  对窗体上任何一个元素的位置的获取，可以使用下面的方法：
	CRect rct;
	WINDOWPLACEMENT* lpwndpl=new WINDOWPLACEMENT;
    ((CWnd*)GetDlgItem(IDC_STATIC_OBJECT_COL))->GetWindowPlacement(lpwndpl);

    其他的函数一般来说不容易达到目标。

2.  在一个矩形区域填充颜色使用下面的函数：
	rct=lpwndpl->rcNormalPosition;
	this->GetDC()->FillRect(&rct,pBrush);

	相对来说，不知道为什莫Rectangle()函数无法内填颜色?


3.  BMP图像中的颜色顺序是 B->G->R，而不是R->G->B。

1.  如何定义常量数组?

    
2.  如何动态创建菜单及响应其菜单条的命令?
