Through COM, one can potentially gain absolute control over a target system. For example: using javascript's ActiveXObject object in IE, one can create certain objects which were designed to have direct access or interaction with system properties and files. One would think common sense dictates users disable ActiveX features in IE immediately after installing the browser to ensure their system is protected while surfing the net, or at least paying close attention to which websites they permit. But, I doubt many average PC users know how or why to do this, or just get tired of mirco-managing it over time. I think any PC user or admin my COM class caters to would greatly appreciate not having to deal with that. Thankfully it looks like IE versions come packaged with ActiveX disabled by default nowadays.
I've built a very versatile COM class library in VB. I didn't intend for it to be callable from any website, but that feature is just part of the COM platform. I'd like to prevent the library from being called from IE unless the website is on a white-listed domain to proactively protect the user (and ultimately their entire intranet) from harm from malicious websites. What would be the best method in VB.Net to tell which application called my DLL, to be able to tell if it was called from any command or process originating from IE? And, what domain called my dll?
Edit: I believe this might be a duplicate. See: Calling Assembly to get Application Name VB.NET
System.Environment.GetCommandLineArgs()(0) gets me the calling application path. With this info, I can compare it to a black/white-list of applications. Problem solved for now.
