Look up the functions:

Thread32First, Thread32Next<br />
<br />

These are used after you create a snapshot with:

Hello.
I'm new in Socket Programming and I found that the sample program in this page is easy to understand.
Attached sample project is working fine in Microsoft Visual C++ Express Edition.

But I had a problem when trying to make an exact copy of the program,
by creating new empty project and add the sources ( attached "sock.h", "sock.cpp", and "main.cpp" ) to the project.
When I trying to build the project, there's some errors as below.

I suppose that the errors came from different "Project Properties".
Anybody could help me?

I using Microsoft Visual C++ Express Edition 2005 with Microsoft Platform SDK for Windows Server 2003 R2 installed.

You need to link to the winsock library: go into the project properties -> 'Linker' -> 'Input' and in 'Additional dependencies' you need to add 'ws2_32.lib'.

Your guess it is right.
You have to add Ws2_32.lib to the LINKER library list.
On my system (VS 2003) this can be done by selecting 'Project->Properties" menu and then (on the newly shown window), after selecting the 'Linker->Command Line', add Ws2_32.lib to the 'Additional Options' TextBox.

It Works!!
Thank you very much( for both Cedric Moonen and Pallini ).
You just made my day.

I also added "odbc32.lib", "odbccp32.lib", "wsock32.lib" to Additional Dependencies,
and it works. But it was derived from yours, so thanks.

There were no error anymore when building,
but when I debug it, there was a dialog bog:

I chose OK and there were no problem ( and the server worked fine ).
Just curious. Any suggestions?

You started to debug your program (you pressed F5 probably) but your program was build in release mode probably. That means that it doesn't contain any debugging information and you won't be able to use the debugger.

swscanf_s(strVial, _T("%d%*s"), &vialNumber)

How many characters does %*s takes in the above line of code

that should be "%s" as in _T("%d%s")

%s takes in a string, so you're missing an argument.

I think your reply is incorrect. See here[^].

An asterisk (*) following the percent sign suppresses assignment of the next input field, which is interpreted as a field of the specified type. The field is scanned but not stored.

humm thanks for pointing that out Big Grin | :-D

I've never used that options, that is to be able to skip the next scanned data.
