The application ZKAccess-3.5 has the ability to enumerate doors, and open or close the selected door.
The sdk has this incomplete API:
VARIANT_BOOL ACUnlock(LONG dwMachineNumber, LONG Delay);
VARIANT_BOOL GetDoorState(LONG MachineNumber, [in,out] LONG* State, [out,retval] VARIANT_BOOL* pVal);
How do I select the door I want to open/close? I have 2 doors. I expected a doorID parameter or something like that.
Device: inBio 260 / 2 doors
EDIT: PullSDK Wrapper in C#, Shows how to use PullSDK
Those functions are not a part of the PullSDK.
ZKTeco claims the standalone SDK includes PullSDK when It does not cover everything (example: ControlDevice function).
The native dll plcommpro.dll is the main dll for the PullSDK.
It exports the function ControlDevice, that can be used to lock/unlock doors, but the documentation is confusing, I'm not sure how to use it, I will try to decompile ZKAccess3.5 to find that out.
int ControlDevice(HANDLE handle, LONG OperationID, LONG Param1, LONG Param2, LONG Param3, LONG Param4, const char *Options)
ZKTeco is not good at what it does (hardware, software, protocols, sdk, docs).
