R – Need message from ActiveX that runs in a thread

activexcominternet explorer

I have an activex control, that I developed myself. The activex runs in a thread to make sure that IE doesn't freeze when its executing the long task. The long task is pretty much looping through 32K rows. Now while its looping I would like to display a message to the IE user notifying him about the row position. That way the user can see the process. Is there a way to achieve this?

Create an property on activex, and check it with javascript.

You could unregister the control with

regsvr32 /u badboy.ocx

at the command line. Though i would suggest testing these things in a vmware.

Way to force IE to unload an ActiveX control

Try the javascript delete statement:

function unloadObject(objId) {

    var obj = document.getElementById(objId);

    obj.parentNode.removeChild(obj);

    delete obj;
}

Call unloadObject(targetActiveXTagId) before opening your second page.

Ideally, you should build the upgrade mechanism into your ActiveX itself. I've seen several online game platforms does this with good results.
