关于 ActiveX控件在IE浏览器中滚动条失效的处理方法

将acitvex 插入到IE 里面后,拉动滚动条,当acitvex 控件有部分被IE 覆盖后,再拖回原来位置,横向的滚动条无法拖动.

这个问题是因为acitvex 控件在IE中没有被重画引起的.

解决思路:

(1)从html的js脚本出发:只要使得acitvex 闪动一下

<SCRIPT>
function doScroll()
{
// "objectEditor" is the name of the control.
document.getElementById("objectEditor").style.display = "none";
document.getElementById("objectEditor").style.display ="";}
</SCRIPT>
<BODY onscroll="doScroll();">

(2)从activex控件内部重画机制出发: onPaint中

// NUMBER_OF_CHILDREN is predefined as the number of child windows
// that are hosted on this control

// m_Children is a member variable of the CWindowedCtrl class that
// stores an array of CWnd references to the child windows on the control.

void CWindowedCtrl::OnPaint()
{
   CPaintDC dc(this); // device context for painting<BR/>

   for(int i = 0 ; i < NUMBER_OF_CHILDREN ; i++)
   {
      m_Children[i].RedrawWindow(NULL,NULL,RDW_INVALIDATE | RDW_FRAME);
   }

   COleControl::OnPaint(&dc);
}
