rfid programming

I have 2 r开发者_StackOverflow中文版eaders for RFID and some cards (from a Chinese company called "Daily RFID"). They kind of work because they came with some demo software written in Delphi that reads the id of the card (myfare compatible, ISO14443A). The problem is that if I try to use the demo to write to them, it doesnt seem to work.

They have another demo written in C#, it compiles and runs, but when click on Connect, I get this error:

Unhanded exception.. unable to load DLL 'BasicB.DLL'

So I put the DLL in %WINDOWS%/system32, but when I tried to run regsvr32 BasicB.dll, I got another error:

the module "BasicB.dll" was loaded but hte entry-point DllRegisterServer was not found. Make sure that "BasicB.dll" is a valid DLL or OCX file and then try again

I have written to the company but got no response.

I program in Objective-C, so I kind of understand c#, but how to make these cards work?

Should I continue with Delphi, and try to write to them with it? Or should I continue trying with C#? Either way, would I have to write the code to read/write to them, or is there any software to work with these modules?

You only use regsvr32 to register ActiveX (COM) DLLs. The DLL you're trying to register isn't one.

Putting the DLL in the %WINDOWS%\system32folder should be enough. In fact, it can be in your applications folder or anywhere on the PATH.
