I would like to interactively detect when an ActiveX component has been installed, and asynchronousl
- by Brian Stinar
Hello,
I am working on a website, and I would like to refresh a portion of the page after an ActiveX component has been installed. I have a general idea of how to do this with polling, which I am working on getting going :
function detectComponentThenSleep(){
try{
// Call what I want ActiveX for, if the method is available, or
// ActiveXComponent.object == null --- test for existance
document.getElementById("ActiveXComponent").someMethod();
}
catch{
// Try again, if the method is not available
setTimeout(detectComponentThenSleep, 100);
}
}
However, what I would REALLY like to do is something like this:
ActiveXObject.addListener("onInstall", myfunction);
I don't actually have the source for the ActiveX component, but I have complete control of the page I am hosting it on. I would like to use JavaScript, if possible, to accomplish this.
So, my question is 1.) will this actually work with the polling method? and 2.) Is there an interrupt/listener like way of doing this? I am sure I am missing something with connecting the dots here, I can already detect if the component is present, but I am having trouble doing this asynchronously.
Thank you very much for your time and help,
