Use C++ dll from Delphi win32

The project is very simple - make an interface unit that allows the use of a C++ dll from Delphi win32 (can be Delphi 7 or Delphi 2006).

I uploaded the dll, the header files and some c++ code example. I need the same functionality from the sample but in Delphi.

It is difficult to test unfortunately because the dll is used to read belgian id cards and I cannot provide a test card reader and test id card.

Nevertheless it should not be a difficult task, only a limited number of exported methods and classes are needed not the complete dll so a purely 'technical' approach is well possible and I will do the testing myself.

The code should take into account the specificities of this kind of communication, more specifically the memory allocation and freeing.

Feel free to contact me for details.

Note that I will ignore any 'bulk' offer from people which obviously did not at least read this description. In order to avoid this please note in your offer which city is the capital of Belgium. Thanks.

Hi, as I know Brussels is the capital of Belgium. VC++ dll with exported classes (your case) cannot be used directly or via any interface unit in Delphi because of the different calling conventions in C++ and Pascal. P Lagi

I am mainly an operating system developer so interfacing between different languages using different calling conventions isn't a problem.

Interfacing between Delphi and C++ should not be a problem, even if the calling conventions are different there are keywords that makes this possible, including memory allocations, pointer arithmetic etc. The underlyin Lagi
