我昏。难道不显示吗？？ 我怎么会显示的啊？

我发现问题了，画的叉被我的图片盖住了！看来这个叉要在图片的显示之后显示！

昏迷。。我都 让你搞 郁闷了

我想用OnDrawItem，就是在那个图片Draw了以后再画叉，可是还是没有！

void JumpingDialog::OnDrawItem(int nIDCtl, LPDRAWITEMSTRUCT lpDrawItemStruct)
{
// TODO: Add your message handler code here and/or call default

CDialog::OnDrawItem(nIDCtl, lpDrawItemStruct);

if(nIDCtl==IDC_STATIC_IMG){//图片ID

int x=100;
int y=100;
CDC *pDC= GetDC();
CPen pen(PS_SOLID,5,0x00ff00);
CPen* op=pDC->SelectObject(&pen);
pDC->MoveTo(x,y-5);
pDC->LineTo(x,y+5);
pDC->MoveTo(x-5,y);
pDC->LineTo(x+5,y);
pDC->SelectObject(op);
pen.DeleteObject();


}

}

笨办法 定时器 10ms 。。 显示出来后，然后关闭定时器

呵呵就是啊，英雄所见啊 :|
