This is the source code to the CMappy plug-in - which was my last plug-in for DBPro.

Usual compiling rules apply - you'll also need the Mappy program installed.

/* The following ifdef block is the standard way of creating macros which make exporting
from a DLL simpler. All files within this DLL are compiled with the CMAPPY_EXPORTS
symbol defined on the command line. this symbol should not be defined on any project
that uses this DLL. This way any other project whose source files include this file see
CMAPPY_API functions as being imported from a DLL, whereas this DLL sees symbols
defined with this macro as being exported.

Can you use a code box?

Ehh..... C++ code?

[sarcasm] noooo [/sarcasm]

lol, j/k

Code blocks dont work with C...

Strange, but true!

Its a bit annoying, but there you go
