这种背景色（PS的透明黑白格子）怎么做
而且背景周围的灰色底色是不会覆盖（闪烁）到黑白格子这块画布上的。

在放大到一定程度的时候，比如画布大于窗口内边缘。才会显示滚动条。灰色区域无论缩小多少，都好象沙漠一样，永远没边缘


[解决办法]
使用：Hatch brush diagonal
填背景
[解决办法]
用for循环fillrect
[解决办法]
怎么可能闪烁！怎么可能闪烁！怎么可能闪烁！怎么可能闪烁！

void CMFCSDIView::OnDraw(CDC* pDC)

// Create a hatched bit pattern.

// Select the brush into a device context, and draw.
CBrush* pOldBrush = (CBrush*)pDC->SelectObject(&brush);

// Restore the original brush.
