I am trying to write a Wake-On-LAN utility for a local subnet. I can do the
Wake-On-LAN, but before this I need to find the MAC addresses on the local
LAN.
I had planned to query DHCP on the WAN to get the MAC addresses, but there
are security restrictions in place that will restrict this. I have therefore
decided to ping all the devices on the local subnet, and then query the ARP
Cache and pick out the MAC addresses. I have got the ping bit (sort of)
working, but I don't know how to get the info out of the ARP Cache using
vb.net. (I can call dos commands and pipe to a text file and extract the info
from the text file, but I would rather query the cache directly).
Does anybody know how to query the ARP Cache with vb.net code? Or can
anybody point me towards some info about this? I have searched the net and
trawled through various forums with no results what-so-ever.
Any help will be much appreciated.
Regards,
Martin

Thanks, that certainly appears to do what I need. It looks like I could even
do away with the ping bit of my code. Now all I need is a vb.net equivalent.

I have a routine that displays 60 items (with thumbnails) per page.
You can click any item and displays a new page with item details. When
the user back pages it runs the query again to display all the items.
Is there a way to cache that page and images so that second query
doesn't execute?
I do offer a pop-up window using Java but is not the default and not
used by many. I'd really like to get rid of that second query. ;)
TIA

OK,
I have a MySQL server running 4.0.12 on a 12 CPU Sun U4500 with 12GB of
memory.
With the query cache running, this machine would noticeably "hiccup"
(just stop responding to requests) every so often and wouldn't squeeze
more then 1000 queries per second or so as a result (heavily mixed OLTP
work, with a lot of SELECT's and almost as many UPDATE's).

I'm running 4.0.18, and the queries in cache variable grew from about 2K
to 30K in a matter of hours when we hardly used the database at all.
Has anyone seen something similar? (The cache size was set to 100M and
cache limit to 5M - if that could have anything to do with it).
Regards.

Does SQL Server have a query cache similar to mysql, whereas the query
result is cached, if the table has not been changed?
If so, please refer me to more info.

Hello,
Running a query for the first time on DB2 takes a fixed amount of time.
But when query is executed for the second time, the amount of time is
usually less since the query is (most probably) cached already.
I would like to clear out the DB2-UDB 8.2 query cache (I want the
previous execution time again).
Any advice would be appreciated.

Some newbie questions.. :-)
First, what is the namespace to use for the Cache class ?
When I use this bit of code I get an error

Hi,
Pretty new to PHP and MySQL.
I have a page on my site that displays a lot of information from
various tables. Currently I have lots of small PHP wrapper functions
around SQL queries to get each bit of information. This results in
maybe 10 queries to display one page, but they are all very small and
simple, and it keeps the PHP looking nice too as they are simple
function calls to get each piece of info, which can be called from any

Hi,
Thought I would post this before I start to bang my head of the table.
I have a query that outputs an array from a table.The output is showing records that are no longer in the table. Even when i delete the table, these records still show. I am using php for my queries. How can I get rid of these annoying records. I think the problem may lie with query_cache but I could be wrong.

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
