Hi all,

I have a need to screen scrape a system running on Linux. I've written a simple VB app that basically seems to work.

My problem is that I need to have this running within an ASP.NET page... and more to the point the page is being hosted on a remote system and the only way to telnet into the linux box is via the users PC. So I need someway of creating a control that sits in the browser, telnets into a system, logs in... navigates through some screens, pulls back data and returns it to the calling ASP page.

Is this possible???

Any help would be greatly appreciated,

Warwick Price

I've asked some other people about doing this. They may or may not know. In the meantime, there seem to be plenty of hits on google, so I would start by reading some of these threads:

Tony,

Thanks for the replies... but I don't know if I explained myself properly.

I need to be able to access the telnet session from within the browser on the clients PC. I don't have access to the machine I'm telnetting into from the server, only from the user's PC.

So what I want to do is have the Emulation control running in the browser that'll login to the telnet session and retrieve data and then send it to the HTML screen. I really don't want to return to the server as... as I said... that I don't have access to the telnet server from there.

Does this make sense????

Many thanks,

Warwick Price

What you are describing in client-side instantiation of the component on a web page, which is what is discussed in all the links I referenced.

You'll need to create a component that gets installed and is run from the client machine instead of the server.

I don't have any examples, which is why I posted the links.

Hey Guys,
Did anyone actually got this to work in ASP.NET? As far as I know, VT is a windows control so it cannot be easily implemented inside of ASP.NET pages. Are there any plans to create a web control?

You can use it for scraping (see the ScreenScrape sample that was installed when you ran setup) but you can't use it visually / interactively.
