Sample code to call dpwin32_coff.obj OR dpwin32.dll using Dev C++
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This project is written using Dev C++ 4.9.9.2 but should also work in other
versions (for olders version you may have to create the project yourself).
The source files in the project are:
File name Folder Description
apitest.c Samples\c main source code file for C
dris.h Samples\c contains the DRIS structure
dpwin32_coff.obj Samples\c\object_modules static object modules e.g. dpwin32_coff.obj
libdpwin32.a Samples\c\import_libs contains the function definitions for dpwin32.dll
Note that the source paths are structured to minimise files. If you want to
move this project the references to these files will probably be no longer valid.
The ObjTest project links to the static runtime library module (e.g dpwin32_coff.obj)
The DllTest project uses the dynamic runtime library (e.g. dpwin32.dll).
The sample code contains 10 functions. You will not need to use all these
functions in your code. Just use which ever functions are most appropriate
and customise in your own way. The sample code is just a guide. You should
implement the protection in a stronger way using the techniques described in
the "Increasing your Protection" chapter of the manual.
Code marked with !!!! are places where you should customise the sample code so
that it will work properly:
* Change the MY_SDSN value to the value of your SDSN
* Change the MY_PRODCODE value to the Product Code in the dongle
* Change the MyAlgorithm code (if you call a user algorithm)
* Change the CryptDRIS code (if you encrypt the DRIS)
* Change the CryptApiData (if you encrypt Data you send to our API)
* Change the MyRWAlgorithm code (if encrypt Data you send to our API using the R/W algorithm)
You will also probably want to replace our error messages with your own.
Note - if you are link the static module dpwin32_coff.obj then you should protect your program.
If you are linking to dpwin32.dll then you need to protect dpwin32.dll and *not* your program.
Because your program is linked to the DLL it is protected. The protected DLL will need to be
in the same folder as your compiled program for it to run correctly.
Note - once your program (or dpwin32.dll) is protected you will not be able to debug
your program - after our API has been called. Our strong anti-debug code will cause
the debugger to throw an exception. If you do want to debug your code then you can
use our debug module: dpwin32_coff_debug.obj (or dpwin32debug.dll), but these should not be
used for release. See readme.txt in samples\c for restrictions concerning the debug module.
Note - if you are interested in creating the libdpwin32.a import library yourself then
read the notes in the MinGW\Runtime\readme.txt file (Dev-C++ uses the minGW compiler).
