Answer 1

随手写的代码，给你参考
case WM_PAINT:       
{          
PAINTSTRUCT ps;     //paint structure          
HDC     hDC;        
if (!(hDC = BeginPaint(hWnd, &ps)))       break;           
SelectObject(hDC, GetStockObject(BLACK_PEN));
MoveToEx(hDC, 0, iHeight-1, NULL);
LineTo(hDC, iWidth, iHeight-1);
SelectObject(hDC, GetStockObject(WHITE_PEN));          
MoveToEx(hDC, 0, 0, NULL);          
LineTo(hDC, iWidth, 0);           
EndPaint(hWnd, &ps);  
}
