How to use fkattend.dll without .h and .lib files?

I want to create my own driver program which directly connects to a Hysoon finger print device. I found that the default driver program uses FKAttend.dll, but how can I utilize it without any knowledge of function prototypes? I want your urgent help!!! Thanks...
PS. If it's impossible, can anyone suggest another way to communicate with the device?
My device model is

C27T-ID

.

What I have tried:

I built FKAttend.lib by using Microsoft Visual Studio Command Prompt's

dumpbin

. But how can i build FKAttend.h?
I've also tried using ZKLib for PHP version to connect to the device by network but it fails to connect. I think that's because the product isn't technically supported by ZKTeco.

Get a copy of Dependency Walker, and use that to find the exported functions. You can then load the DLL directly ans call the functions. However, you will still need to find out what parameters each function expects.

I've tried your suggestion, but without any function signature how could I use them...

Dependency Walker shows functon signatures.

Solution 1

If you don't have the .h files, or the documentation on the .DLL, or a support number for the company that made that library, you don't use that library. It's that simple.

I would try to contact the Hysoon support. I see on their web page they provide a software SDK[^].

Thanks for your attention! But for some reason, I can't follow your reference link.(That site is BLOCKED for me :(.) Would you please upload that SDK on Code Project or GitHub? I'm waiting for your help now...
