關于 ActiveX控件在IE浏覽器中滾動條失效的處理方法

2023-05-03 12:04:28

将acitvex 插入到IE 裡面後,拉動滾動條,當acitvex 控件有部分被IE 覆寫後,再拖回原來位置,橫向的滾動條無法拖動.

這個問題是因為acitvex 控件在IE中沒有被重畫引起的.

解決思路:

(1)從html的js腳本出發:隻要使得acitvex 閃動一下

function doScroll()

{

// "objectEditor" is the name of the control.

document.getElementById("objectEditor").style.display = "none";

document.getElementById("objectEditor").style.display ="";}

</SCRIPT>

(2)從activex控件内部重畫機制出發: 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);

}
