Almost there: I expect that the browser, not the server, will launch the app in this case. I think it might have to be done via a URL moniker, like you get on the http://www.bitzi.com site. These will activate file sharing programs such as KaZaA and pass the download parameters into the program. My additional requirement is that the Windows Forms app can activate the browser instance (IE in this case) that created it and get it to navigate to a URL on completion of the process. Simple, eh? :-/

I have a legacy business application written in VB 6.0. (I expect I will need to upgrade this to VB.NET at some point.). I need to activate this from a custom URL link on a web page in IE, passing parameters into it via the URL. This will bring up a form in the VB app from which I can hit a button and return to the IE window page, passing the return values again as a URL. Does anyone know how to accomplish this? I've looked at 'monikers', but I really don't understand how to use these and would appreciate some sample code from someone who has done this beforehand
