Adobe Flex ExternalInterface使用ActiveX调用Javascript

Question

我可以使用ExternalInterface调用来调用Javascript;但是，在JS实例化ActiveX对象时，代码中断并无法继续。据说，Flex正在使用我的浏览器（IE）ActiveX设置。当我在IE中测试代码时，代码可以工作，但不能通过Flex 4.6。代码一直工作到第5行，这是调用AcitveXObject函数的地方。有任何想法吗？ JS代码如下。

function getAD(type) {
alert("blah");

 var wshNetwork = new ActiveXObject("WScript.Network");
 var uName= wshNetwork.UserName;
 var userName = uName;

 alert(userName);

 objConnection = new ActiveXObject("ADODB.Connection");
 objConnection.Provider="ADsDSOObject";
 objConnection.Open("ADs Provider");
 objCommand = new ActiveXObject("ADODB.Command");
 objCommand.ActiveConnection = objConnection;


 objCommand.CommandText = "SELECT sAMAccountName, givenName, SN, mail, displayName,  title, department, department, telephoneNumber FROM 'LDAP://xxxx.net/OU=_Users,DC=xxxx,DC=net' WHERE sAMAccountName = '"+userName+"'"; 

var objRecordSet = objCommand.Execute();



 var userMail,lastName,firstName;
 if (objRecordSet.RecordCount == 1) {
  objRecordSet.Movefirst;  
  userMail = objRecordSet.Fields("mail").value;
  firstName = objRecordSet.Fields("givenName").value;
  lastName = objRecordSet.Fields("SN").value;
  displayName = objRecordSet.Fields("displayName").value;
  title = objRecordSet.Fields("title").value;
  dept = objRecordSet.Fields("department").value;
  phone = objRecordSet.Fields("telephoneNumber").value;

test = objRecordSet.Fields("department").value;

 }
 else
 {  
  userMail = "";
  firstName = "";
  lastName = "";
  displayName = "";
  title = "";
  phone = "";
  dept = "";
test = "";
 }
 objConnection.Close;

 //return userMail+";"+firstName+";"+lastName+";"+displayName+";"+title+";"+dept+";"+phone+";"+test;

if(type=="email"){
    return userMail;
}else if(type=="title"){
    return document.write(" "+title);   //return title;
}else if(type=="displayName"){
    return document.write(" "+displayName); //return displayName;
}else if(type=="phone"){
    return document.write(" "+phone);   //return phone;
}else if(type=="dept"){
    return document.write(" "+dept);    //return dept;
}else{
    return document.write("not found");
}


}
