Detecting plugins in Internet Explorer without instantiating an object

Typically, when you use VBScript or JavaScript on CreateObject to detect a plug-in, the user gets a "jarring" security exception.

What are good ways to detect IE browser plugins without actually creating the object?

While I'm not sure if it is possible to test the creation of an object, you can get around the security exceptions with a try-catch javascript block.

For example:



function checkForObject() {
   try{
      var conn = new ActiveXObject('Msxml2.XMLHTTP');
      return true;
   } catch (e) {
      return false;
   }
}

In this case, the actual error is captured and hidden from the user.
