C++ in Labview 5.1 examples....

[Peter Reeves-Hall]

Hi all,

I'm after straight forward examples and code showing how to include C++
code in labview 5.1

I have access to MS Dev Studio 6 Pro, and am familliar with C++ but not DLL
creation.

The supplied "Hostname" example will not compile in a (C++) DLL workspace,
I've fixed some basic problems with variable types and linking to the
"LabVIEW\CINTOOLS\extcode.h" header but now I get:

LVDLL.cpp
Linking...
Creating library Debug/LVDLL.lib and object Debug/LVDLL.exp
LVDLL.obj : error LNK2001: unresolved external symbol _DSSetHandleSize
Debug/LVDLL.dll : fatal error LNK1120: 1 unresolved externals
Error executing link.exe.

LVDLL.dll - 2 error(s), 0 warning(s)


Any ideas?
commenting-out the offending line means the DLL will
compile, but it looks
kind of important!

Thanks in advance,

Peter Reeves-Hall
