Unknown DLL, using

[Sonnich Jensen]

Hi all

A friend of mine uses a programme called ELS Cash Loader. It is a
programme, which can "load" money to a cash card (any card), for use
in washing machines etc. She has a USB thing for it, where she plugs
in the card, and can read and write the amount.

Now, this is basically a card with a number on it - and it does not
work on Win7 - so I tought - that connecting to this DLL (and the
driver?) I can easily create a small app in C# for Win7 - which can
read and write those numbers.

I recall a programme, which could open a DLL and tell about the
interface - it should be easy, but I cannot find it anymore.

The dll and driver is here: http://hot.ee/sonnich/upload.rar

Can anyone suggest something?

It is a Win32 DLL, so you need to:
- DllImport the functions you want to use
- call the functions as thy should be called

The necessary information is not present in the DLL itself, but
it seems to be available on the net:
