Hi All!
I am trying to use pipes in win32
in my main program (in C) I have:
FILE *fd = _popen(perl d:/umts/catch_in.pl , wb);
int i=12;
fwrite((void*)i,1,4,fd);
ie=fflush(fd);
_pclose(fd);
my perl code (in catch_in.pl) is :
-
use strict;
use warnings;
You can't.
IO::Select with pipes and file handles is only supported on Unix.
IO::Select on Win32 only works with Sockets.
Cheers,
John

This works ok.
But with uncommented cycle
prog catch_in.pl hangs !
My question is - why can_read
always return empty array
in spite of fact that there are data ready for read ???
P.S. I tried can_read() also
It's
In this below example, I want to transfer the output of one file to the
other file
for reading and then take the average of every column. Do you have any
idea about why column_average function doesn't works when multiple files
Are passed using the for routine?
#!/usr/bin/perl -w
use fileoprn
$last{substr($_,0,4)}=$_ for @myArray;
print join \n, sort values %last;
Whoops, one thing wrong with this ... since you don't
sort before creating your hash, if the order of the data was
such that the newer version appears earlier in the array,
your results are wrong.
Anyway

Hi, all.
There is Win32::PerfLib.
It works fine for getting existing perfomance counters, but probably lacks for
the ability to create your own.
Is there a way to manipulate Perfomance Counters in such way?
Thanks,

I have a potential project which may need to connect to DB2 on an
AS/400. They want the app to run on windows. They use 'client access' on
their windows machines to connect to the system. I have not worked with
AS/400 systems before so my first question is does the DBD::DB2 package
support using
Yah, ot I know, but who else writes CGIs but perl guys? :-)
However, the CGI model has an important drawback: a web server that wants
to use a CGI program must call a new copy in responce to every incoming
web request.
With respect to perl, is that still true?
Thanks Peter, that will help.
I am wondering if the use of anonymous hash and array
may make more sense here than doing a bunch of `grep`.
Can somebody show me how I would use it here?
This isn't anonymous, but here's how I'd tackle it:
### untested

my %totaldups;

Thanks Peter, that's basically what I was looking,
something more than the single hash I had.
Now I have to figure what goes in these two lines
$page++ if /some page match here/;
$section++ if /some section match here/;
But with some effort I should figure it out.

Hi
I want to know whether using CGI and using pain html is faster or what?
If I use CGI to generate the html and write pain html code inside Perl to generate Html. I believe write pain html inside Perl is more faster then CGI generate html code.
What do you think ?

Hi,
when I use
Tk::MainWindow(..)
with
system(..)
the system-call slows down. In Debug-Mode (Komodo) the last line will
never be reached!!!
Example:
use Tk;
MainWindow-new(-height = 1)-messageBox(-message ='Hallo ');
system(dir);
print Never comes to
16 matches
