Hi All
I apreciate if anybody help me in this little problem...
I just want to store an image from a url in a variable, but sometimes anything go wrong, and the routine can't open the url...so i create this code:
$size = 0;
use LWP::Simple;
while ($size == 0) {
my $data2 = LWP::Simple::get $site;
my $size = length($data2);
print "$size\n";
}
My wish is that, when the image are really stored in variable $data, the loop stop, and the programe continue... but my problem is that the loop is continually looping..
Somebody can help me?

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

or How to display code and escape characters
are good places to start.
