Activex Componants, Visual Studio.net and C#.net

[Heple]

As part of a university project i have to a create an activex componant that times the download of a file of known size. This is so that my website can measure the bandwidth of any client machine that accesses it.

 

I am coding my website in C#.net using visual studio.net 2003, i have never used activex before and am unsure of how to link my web site to an activex componant let alone code the activex componant.

 

Below i have wrote an algorithm of what i believe the activex componant will do. I am unsure of whether this is correct.

 

Start download

Start timer

Error = False

while error = false

while (timer<given threashold) AND (download is finished)

Stop Timer

Return Timer value

else

error = true

end while

 

 

I would be grateful if someone could send me a small activex componant and let me know how to call on it in my visual studio.net web application, just so i can practice using activex with visual studio .net 2003.

 

I would also be grateful if you could advise me whether i am on the right track with the activex componant that i have to design to measure bandwidth.

 

Thanks

Anyone?

 

Your help is much appreciated.

http://newmedia.northatlantic.nf.ca/multimed/source/techspec/activex.htm gives a brief overview of activex controls and how to use them in IE.

Creating an ActiveX control can be a difficult job depending on your language choice (C# doesn't have any built in support for this) though.

How do you call on an activex control from visual studio.net 2003

You can add it as a reference to a project and treat it like a .Net library.

Thought it would be along them lines.

 

Has anyone got any advise as to how i would go about creating an activex componant, that measures the amount of time it takes a file to download to a client machine?

 

Would the activex componant actually initiate the download and time it or would i do this in my web application then call on the activex componant to time it?

Do you need a client side activex control? or a server side COM control?

I would like to see the exact assignment requirements.

 

ActiveX usually implies user interface. This will be embeded and instance in the client browser via an <object> tag. you can't create a pure activex control with .Net.

 

google "media player in web page" for an example of embedding activex.

[Heple]

The assignment requirements are pretty open.

 

All that is required is that i create a web site that measures the bandwidth a client is recieving when they download a file from the site.

 

such as : http://www.zensupport.co.uk/speedtest/results.asp

 

I was advised to use activex.

Well I'm not sure who advised that but I see no need for activex, the way the page you used as an example works is it takes the time, sends a specific amount of data, then takes the time again. Then it just finds out the difference between the two times and thats how long it took.
