Well, FindWindowText will return undef if it can't find a window that matches the given criteria. So how about doing something like this:
my $win;
do {
select(undef, undef, undef, 500);
$win = FindWindowLike(0, "", "FOO");
} until ($win);
And just replace 500 with the number of milliseconds you'd like to wait between each check.
The computer can't tell you the emotional story. It can give you the exact mathematical design, but what's missing is the eyebrows.

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).
