Re: naive LWP::Get question (perhaps JavaScript related?)
Hello, If you can use Firefox, there is a handy extension - HttpFox, which displays all requests which are sent to the server (including AJAX). This way you can forge the same request in your perl script and call it just like client side browser script does.

Bidirectional non-blocking IPC
Hi, I'm working on a Perl daemon which will run PowerShell scripts. The essential part is to start a powershell.exe child process, feed it data on STDIN and read it's response from STDOUT. Apparently IPC::Open2 is limited to UNIX systems. What is the best way to do bidirectional, non-blocking IPC on Win32? Please provide a short example if possible. -- Regards, rocku ___ Perl-Win32-Users mailing list Perl-Win32-Users@listserv.ActiveState.com To unsubscribe: http://listserv.ActiveState.com/mailman/mysubs
Re: Resolve hostname by specified nameserver
No, it's not pure Perl. It uses some XS code. I can't use it since in my
project I am limited to standard ActivePerl modules. I could, of course,
copy it if it wasn't for this C code.

Resolve hostname by specified nameserver
Hello,
I need to resolve a hostname by a specified nameserver. Currently I am
using nslookup throught backticks, but it's output differs slightly
between Windows versions and is hard to parse. I wanted to use Socket
and something like inet_ntoa(inet_aton('hostname')) but this way I have
no option to specify the nameserver to query. I am aware about Net::DNS,
but unfortunately I cannot use it because it's not standard in
ActivePerl 5.10. An ideal solution would be some WMI function, but I
cannot find any for the task. Maybe using Win32::API?
So my question is - how to query a specific nameserver about a DNS 'A'
record?

As Rob May responded, it is possible to copy from MsgBox, the user just has to press CTRL+C and window's content gets copied to clipboard. That will do for me.

Re: Win2008 / Vista UAC - elevage privileges
Thanks for your reply, but that's not what I'm looking for. I should have described my problem more precisely. I'm working on a Perl program that will be run on different Windows Server machines (actually, it has a cmd wrapper that launches the actual Perl program embedded inside it). On Windows Server 2008 it requires the user to confirm the elevated privilege dialog, which I can't get to show up. I found a solution described here: http://stackoverflow.com/questions/150782/windows-vista-how-to-execute-a-exe-program-in-the-cmd-as-an-administrator/150911#150911 It is based on a weird fact, that Windows with UAC launches the elevated privilege box when there is 'runas' string at the end of arguments. However, it required using two separate scripts, one of which is a VBS script and the other is cmd. I've managed to cut it down just to the VBS script, but that's still not what I'm looking for, since my wrapper is cmd. The bottom line is that I'm looking for a solution to show the elevated privileges dialog box.

Increase pipe buffer size
Hi all,
I'm using ActiveState Perl 5.10. Is there any way to increase pipe's
buffer size? By running the included sample script, I found that (at
least at Windows Server 2003) it is limited to 512 bytes. I am aware
that Win32::Pipe has a method which allows to alter the buffer size, but
it uses some C code to do it. Is it possible from Perl?

DMI BIOS information
Hi, I'm working on a script which will be responsible for gathering various hardware information. Most of it I would like to get from BIOS's DMI. However, I cannot find a way to access this kind of data from withtin Perl, nor do I have a suitable CLI tool to report this kind of information. Under Linux I would use dmidecode. So my question is - how to get DMI BIOS information from within Perl in Win32 environment? -- rocku ___ Perl-Win32-Users mailing list Perl-Win32-Users@listserv.ActiveState.com To unsubscribe: http://listserv.ActiveState.com/mailman/mysubs
