what you want actual Lan Speed which can be easily found out by using GetIpStatisticsEx and if you want LanSpeed printed on LanCard .. i soubt you have to use WMI

You need to know the engine type of your LAN. If you are planning to increase the speed, use a High octane fuel. Tubeless radials will be an added advantage. If I were you, I would not mind spending a little more to get a couple of nitrogen boosters fixed to boost the speed. And you obviously need a ~~speedometer~~ LanoMeter to check the LAN speed. It is available in all leading ~~automobile~~ LanoMobile stores. See you at the international lan race at Tokyo. Bye for now.

Hello,
i have an application in which i use a mysql-database.
the connection is done with the mysqlpp-api.
if i compile (visual studio 2005) the programm in debug mode everything works fine but if i compile the programm in release mode then the programm aborts when trying to create mysqlpp::Query object.
( mysqlpp::Query test = connection.query(); or mysqlpp::Query *test = new Query(connection); )
i get an access violation at adresss null.
i tried to disable all the optimizations in the release configuration. but it does not help.
could it be that i have to allocate extra memory befor trying to create an object?
is it possible to allocate initial e.g. 30mb of memory?
and if yes how?

thanks

There are different possibilities for this. I suggest you to read this[^] article by Joseph M. Newcomer.

I am working in EVC for socket and am getting the follwoing errors .
I have included Ws2_32.lib and Winsock2.h .

error C2065: 'WSAAsyncGetHostByName' : undeclared identifier

may be because the INCL_WINSOCK_API_PROTOTYPES got define before including the winsock2.h . I dont know how it got define.

Try including "winsock2.h" above all other includes.( if ur using stdafx.h, put

#include winsock2.h above the first include in it)

try this. I am not sure whether this a right way to do. How ever if the error was because of the pblm I above mentioned, it will compile fine when wrote as below

#undef  INCL_WINSOCK_API_PROTOTYPES<br />
#include <WinSock2.h>

It because of your logic. You are using boolean operation as case input. Which is repetitive. case should be different in switch statement.

This is wrong. This will in fact evaluate to a boolean, not a character. What you need to do is this:

case('m'):<br />
case('M'): <br />
// Code here<br />
break;<br />

What is the cause for this error?

you only have to use constant in case field.. switch case just work like goto statement but with scope
