I need to read and write to an ActiveX control located in a broswer that accesses a mainframe. It is a simple command line interface (strictly text), and I believe it might be based on a citrix interface. I would like to be able to send a command and read via code the result. Can anyone give me some guidance on how to start this?

Does the ActiveX control already exist, if so is a description of the API available for it? If not you can import it into a win or console app to at least get intellisence.

Otherwise the object tag is just any other part of the DOM. You can get access to it via it's id like any other element. If the control is successfully loaded (both installed and having no browser security issues) then you can use it's methods and properties as you would in any win or console app. I have encountered issues where javascript would fire after loading the page but the control had not yet initiated. This is easily mitigated by setting a call back via timer.
