asp.net - Virtual Directory root vs Default web site root -

-

i using iis 5.1 in have only 1 default website,

i have 2 projects v2 , v3

my website points v2 projects , have folders images, styles etc have virtual directory under website hosting project v3 , having same folder hierarchy v2

in home page of both projects have

img src="\images\edlogo.gif" alt="logo"/>

but shows same image in v2 directory, how can show different images both projects. using "\" root of web site how can root of virtual directory under website

this static method returns full http path root folder of application (web site or virtual directory)

public static string getapprooturl(bool endslash) {     string host = httpcontext.current.request.url.getleftpart(uripartial.authority);    string approoturl = httpcontext.current.request.applicationpath;    if (!approoturl.endswith("/")) //a virtual    {        approoturl += "/";    }    if (!endslash)    {        approoturl = approoturl.substring(0, approoturl.length - 1);    }    return host + approoturl; }

so, can write in page:

<img src="<%= server.htmlencode(getapprooturl(false)) %>/images/edlogo.gif" alt="logo"/>

(or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

example preg_replace('/\{[a-za-z.,\(\)0-9]+\}/', 'replaced', 'lorem ipsum dolor sit {tag1({tag2()})}, consectetur adipiscing elit.'); the result: lorem ipsum dolor sit {tag1(replaced)}, consectetur adipiscing elit. question as can see "tag2" has been replaced, want replace "tag1" know how can this? (in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
