Dlls in a browser

[RichyRoo]

What do you need to do to a dll to allow it to be activated in a brower by a URL..

i.e.

http://www.website.com/component.dll

(i'm happy about dlls and com, but want to make the browser run it) and i've seen it done!

regards

are there any tutorials anywhere

are you thinking about ActiveX controls?, if so you need to use the <Object...> tag, plus it only works in IE, you would have better luck using the ActiveX dlls, and what not on the serverside (which would require NT4 w/ IIS4+)

ive seen an app which uses a url or

http://www.dddddddd.com/dllname.dll

i have done asp and html with com components into it, although this seems even more powerful..

i believe you can put an exe in a url as well...

anyone know how?

i've tried creating a component and setting the default method... but it didnt seem to work

unless you actually know what that dll is I dont know, but I have seen

http://..../something.dll?someparam=meters....

if that is the case it may be CGI. so you might want to look into that. I just know that if it is CGI, dont expect to write it in VB, as many people who have tried, ended up getting very very slow CGIs

thanks karl

that is what i'd seen

i was wondering how that actually runs the dll, i.e. what method it envokes?

cheers

Here's a good place to start.

There is another category of usage for DLL's called Server Extensions (kb244 describes it's usage above). I'm not sure how you'd build an IIS Server Extension (vs. a Component) in VB, or even if this is what you would want to do.

 

[Karl Blessing]

in almost all the serverside componets, will often use the ?variables=values.... , in ASP you grab it with Request(&quot;variable&quot , similar methods in CGI and server extentions. Only real big difference, is that raw ASP is interpreted, server extensions, and CGI, are precompiled.

... no, no, no; category or type of use. As in, do I wish to create instances of components within the application which will not require arguements directly or a Server Extension external to my application which will uses arguements exclusively to identify its' use?

i'm a bit confused now..

you can actually run an exe in the browser, (or in my case hopefully a dll)

i'm okay with the arguments part of, i just want the dll to run a default method..

so if i have

http://www.somewhere.com/thedll.dll

thedll will run, running a default method,

the question being what additional coding is required to the dll (apart from setting a default method) putting output to the browser.

sorry if i'm confusing everyone!

Richie, I've only ever built IIS Components using Visual C++. I believe that the links, above or below, will provide you with the information that you need concerning the use of VB to create Active X components and/or Extensions for use under IIS.
