How can I cause a file download using the browser?

I have tried http:// and ftp:// but ftp doesn't work at all...something about a gateway. I don't really care!!!

http:// downloads files only if it doesn't have a registered file viewer which can treat a browser window as an container. For example PDF files don't download, they load into adobe immediately.

I am assuming this is done on the server side of things then...

Do I have to send headers with the file mime-type as some strange mime-type that IE won't automatically try and open the file's associated reader, etc...?

What mime-type do I use? and what other header do I send so the browser knows what file to download...?

Thanks Smile | :)

The way I do it is via perl. It can be done in any server-side language, however. You have to set the mime type to application/x-download and then set a content disposition as well. In perl the code looks like this:

print "Content-Type:application/x-download\n";
print "Content-Disposition:attachment;filename=$filename\n\n";

where $filename is the name of the file you are forcing a download.

In other languages, you would have something similar, though this is the main concept. Do a search for the server-side language you would be using and keywords like "force download" or something like that and you will see examples of code kinda like this.

Page display with DIV or SPAN

Cool...those look like the headers I need.

I wasn't sure if thats how you did or not, so a second answer is awesome.

I want to display a webpage within a DIV or SPAN - is that possible? For example, I want a DIV region on my parent page that loads Google into it - sort of like frames, only I need custom sizing and positioning beyond what frames are capable of. Confused | :confused:

When you refer to frames, I assume you mean iframes.

I'm not sure, but using CSS cannot you not control IFRAME as much as you could a DIV?

Have you tried??? I don't see why you couldn't resize and position an IFRAME anywhere using:

style="position: absolute; top: 100px; left: 10px; width: 50%"

There is a way to display foreign source HTML in DIV's, however it's one hecka of a hack, not search engine friendly nor is it cross browser (actually you can make it cross browser, but it's a lot of work)

For this reason I suggest using IFRAME's and doing the CSS thing if you can. In fact both solutions require atleast a single IFRAME anyways.

Keywords and Search bots

aside from a site using META tags to specify keywords that search bots can use, HOW ELSE can a search engine be directed to one's site when someone "Googles" a topic?

I'm curious as to how my site could be identified when somebody looks for something that may or may not be related to my site's content. What brought visitors to my site?

Any ideas on my question?
Thanks,
Johnny

Simply said, content and reputation of your site brings visitors.
Content - that's obvious, I think e.g. google indexes every word on your site, not only keywords. So more accurate your content is, the bigger is chance that search will show to user what he's looking for.

reputation - the more sites links to your site, the higher position in google's results you have.

>How was my site discovered?

The reason I ask is security, for example.

Say I posted something that I didn't want to go out and didn't catch it for say 2 months. Aside from the obvious that I could look at on my page (META tags and like you said individual words on the page) are there other considerations that could have directed UNWANTED traffic to my site

Domain name? IPs? Corporate affiliation? Etc....

Thanks again.

you didn't write this before! Confused | :confused:

I don't understand to your question than.

Do you want to know how ban search bots? Or how to delete your site from google's database? Or what? Oh wait.. you want to know ways how people can find your page! yes? D'Oh! | :doh:

Yes, I want to know how people can find a page.

Example, say I hosted a page on a university (educational instution) server in the USA. If I had:

1) META tags that keywords are "MATH SECRETS" and "ALGORITHMS".
2) The content, "How to develop mathematical algorithms"

Could a search (BOT, person initiated) identify my page by:

a.) IP   (whatever.edu)
b.) location  (USA)
c.) META keywords  ("SECRET" and "ALGORITHMS" as words by themselves)
d.) the content   (the individual words by themselves too)

e.) >> ANYTHING ELSE??

Thanks again for this info - curious.

I am not that stupid. I know what "university" is. I study at one of them Wink | ;)

Only one thing came to my mind ... personal information about domain owner (WHOIS service), bt it doesn't identify author of the page.

So answer is.. AFAIK, nothing else. Anyway, I don't know much about security issues and about networks. If I knew what your original post was about, I wouldn't answer it Blush | :O

you can also use the "robots.txt" file in the root of your domain. in this file you can specify whether or not a search engine's crawler (like googlebot, for instance) may crawl your site, even to "you may not search <this> page" point.

that's the only thing i can think of.

sure. That's what I meant by question "do you want to ban searchbots"? It applies only to well-behaved bots, however. Better way can be check user agent's name after request, and send the right response (e.g. "get out of there", or act this is 404). And from last of Johnny's posts, I thought he wants to know what information bots can get once they reach his site. Bt I don't understant to his goal, to be honest.

How can i capture save dialgog box events like save, cancel, open etc

Re: Dialog Box

If you are talking about an ASP .NET file control, the answer is that you can't. The dialog is opened on the client side and therefore no events are fired on the server until the form containing the file control is posted back to the server--at which point the dialog is used and gone.

You could probably write an activex control and embed that in the page, but activex can be a real security risk and it would only work (reliably) with Internet Exploder.

Best Regards.

What are meta pointers and meta classes?

4-Dec-04 1:55

Sure can!!!

Assuming 2 conditions:

1) I think it only works under IE
2) You must prompt the user to save the document. If they travel through the menu in IE and click 'Save As' this doesn't work.

<button onclick="javascript: document.execCommand('SaveAs','1','Default.htm');">Click to save</Button>

Where SaveAs is the command and Default.htm is the suggested name you want users to use when saving your page on their HDD.

I'm not sure exactly what the meaning of meta is, but it's to best understanding that META usually means something that doesn't really exist. Which makes defining it even harder. How do you define something that doesn't exist.

META when used in programming...for instance while reading an article on parsing and EBNF grammars, stated that EBNF is a META language. EBNF, in this case, is a language which dictates the exact syntax of another language.

META tags in HTML (AFAIK) are keywords but...not really keywords...keywords should come from the content of a site's document.

META classes, going on what i've learned through osmosis about what META means and is...and listening to my sister ramble about the meanings of life (I say it's pointless then you die) and the meta physical aspect of things...like if you really focus and really want to...you can walk through that wall (I say not a f*ckin chance, you try it, running full friggen speed too and when you, as in she, my sister says OUCH!!! I'll say I told you so).

Anyways...back to META and it's meaning...what i've gather over the years and through context when i've seen it's use in an programming article or conversation, is that META is kind of a paradox.

So to address your question of META classes...

My best guess, would be an UML diagram. It's generic as far as typical class layout or syntax is concerned and yet it symbolizes just that...a class...not an object, but rather a blueprint for any object. A UML diagram is easily converted into any "REAL" class using the syntax of any given language and yet is easily understood by any reader familiar with UML and OOD principles. Doesn't matter whether they are CPP or Perl or PHP or JScript or whatever.

Thats my best guess...

As for pointers...well a pointer when you speak technically is a very specific thing. It's a variable which "Points" at another variable. So a META pointer...an imaginary pointer for the sake of connecting two object diagrams, etc...
