Beginner Sockets examples...

[godofcode]

I've written socket clients and servers in Visual Studio / C++.   However, now I'm trying to write them in LabWindows/CVI and having difficulty to get them going.  I not finding too many indept starter guides / examples for creating a simple server and or simple client.

Does anybody know where to point me?

Thanks!

CVI ships with multiple example programs on datasocket.  How you find them depends on what version of CVI you have.

In CVI 9.01, go to Help >> Find Examples, then click on the Search tab and enter DataSocket.

In CVI 6.0, go to Help >> Contents, then click on the Index tab, enter Example, then double-click on Example Programs on the left, then on the right, click on Communication, then DataSocket.

 In either version, you can then scroll through the examples and see a description of each example.

when you say that you wrote clients and servers in visual studio, which library were you using ? if you were using the WinSock2 C API which is part of the Windows SDK, it is available with CVI provided you installed the Windows SDK. (if on the other hand you were using a wrapper like MFC socket classes, you are screwed).

CVI ships with its own TCP library which may seem a bit malformed for someone who has already used the standard socket calls: the CVI TCP library makes a big distinction between a client and a server socket, read and write calls are different for the 2 kind of sockets. this distinction always puzzled me and is not representative of the way a tcp connection works, so be prepared for a headache when you start using this library.
