Releasing JavaScript ActiveXObject ()?

Question

I call C # COM component using javascript: keystore = new ActiveXObject("RBCrypto.KeyStore");. I noticed that this instance remains until I exit the browser. Is there a way to “release” this object when the user leaves the page? I am currently using:

window.onunload=function() //when a user leaves the page close the keystore
{
     if(keystore != null)
     {
         try
         {
            keystore.closeKeyStore(); //method in keystore
            delete keystore;
         }
         catch(err) { alert(err.description); }
     }  
}

But the COM object is still in place. Any ideas?

Answer 1

I know it's a bit late to answer. "Until later than never"

, : "Application.Quit();". Object COM/OLE/ActiveX null. , return Application!= Null Quit();

...

try
{
    keystore.closeKeyStore();
    delete keystore;
    keystore = null;
    CollectGarbage(); 
}
catch(err)
{
    alert('freeing ActiveXObject via javascript'+ err.description);
}
