It is always a good Idea to set your object to nothing when finished. In ASP unless otherwise set Objects have page scope. That is to say if you create the object on the page when the page is finished being used the objects will be cleaned up.

That seemed likely, but VBS is new to me. Better to form good habits now, than to try to break bad ones later... Thanks for the info Smile | :)

Get Host Address

I am attempting to move my old asp code over to asp.net but have run into the following problem. Inside a class page I am trying to get the host address. The Request.UserHostAddress function works perfect in the aspx page but will not work in the vb class. This is because Request is part of the Page method which is not available to classes. The obvious work around is to pass in the address from the aspx page, but I would like to know if there is a better way this could be done. I appreciate any help that can be provided.
Thanks
Jason

Why do you continue to ask PHP questions in a forum about HTML/ASP/ASP.NET? Mad | :mad:

You might get a better response by finding a PHP forum.

Or by not deleting the post so that when someone who actually knows PHP stops by can answer it. What's the question and who asked it?

me.

i noticed a function, unset, and wondered if you were supposed to use it to destroy variables at the end of functions.

You can use unset() to explicitly destroy variables, but variables are destroyed at the end of the life of their scope anyway. So, unless they are static or have global scope they'll be cleaned up at the end of the function. For instance, if I use a local variable $foo in the function bar, it'll be destroyed anyway when bar returns.

In short, you don't have to. And, you'll find this method of variable handling holds true in many languages other than just PHP.

Hmmm...ok, I'm stumped here, reading Professional ASP.NET from Wrox and it says in Ch. 23 that to get the IP address of the user from the Request object you use UserHostAddress and to get the browser you should use UserAgent, however I can't get either to work at all, does anyone have any clues, the only example I have seen is a really ugly iteration of Request.ServerVariables through several arrays which I feel is a tid bit much. Where am I going wrong here? Confused | :confused:

Thanks in advance.

The Request.UserAgent and Request.UserHostAddress should work fine.

Try creating a file called "test.aspx", and paste in the following:

<script language="vb" runat="server">
Sub Page_Load(Sender As Object, E As EventArgs)
	Response.Write(Request.UserAgent & "<br />")
	Response.Write(Request.UserHostAddress & "<br />")
End Sub
</script>

Load that page and see what happens. On my machine, the response is:

Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; Q312461; .NET CLR 1.0.3705)
127.0.0.1

Yeah, I actually got it last night, I was trying a little too damn hard thinking that I would need to do something like Response.Write(Request.ServerVariables("UserAgent")) when all I needed to do was drop the ServerVariables("") stuff. Thanks for the response. Smile | :)

I've had a Brinkster website and it wasn't too bad.
They do advertise it as more of a demo/prototype/test environment than a production site.
