滚动条问题 ，为什么是iVertPos-si.nPos，而不是si.nPos-iVertPos,

si.nPos-=si.nPage; break; case SB_PAGEDOWN: si.nPos+=si.nPage; break...if(si.nPos!=iVertPos) { ScrollWindow(hwnd,0,cyChar*(iVertPos-si.nPos)...

si.nPos -= si.nPage ; break ; case SB_PAGE...(si.nPos != iVertPos) //如果滚动条发生变化了...y = cyChar * (i - iVertPos) ; //获取重绘...

y = cyChar * (i - iVertPos) ; TextOut (hdc...si.nPos -= si.nPage ; break ; case SB_PAGE...if (si.nPos != iVertPos) { char buf[100]...

//滚动条位置 static int iVertPos,iHorzPos,iPaint...si.nPos -= 1; break; case SB_LINEDOWN: ...ScrollWindow(hwnd,0,cyChar*(iVertPos-si.nPos),...

我们的程序急需一个垂直滚动条,而暂时还不需要水平滚动...(hwnd, 0, cyChar*(iVertPos-si.nPos), NULL,...y = cyChar * (i-iVertPos); y的值变成了48,...
