-Use of zkemkeeper.dll

[Adolfo]

Anyone with experiences using this dll
I Think is written in VB, can we call it from Harbour?
I use Borland as mi C Compiler, would it be better to change to Microsoft C ?
Can I transform it into a lib with implib and use it as any lib ?


Any help will be appreciated

Adolfo,

I use this .dll as activex.

I use it on my Bio-metric device to retrieve log records.

Adolfo,

I don't have the leisure of time to re-create a small sample but this is part of my code:

runtime files I'm using are:

1. commpro.dll
2. comms.dll
3. msvcr71.dll
4. zkemkeeper.dll
5. zkemsdk.dll
6. zkemkeeper.oca

to check if object was registered:

Code: Select all  Expand view

IF !IsActiveX('zkemkeeper.ZKEM.1')
     RegisterServer( 'zkemkeeper.DLL' )
 ENDIF
 

to connect:

Code: Select all  Expand view

  ...
  oBiometric := TActiveX():New( oWnd,'zkemkeeper.ZKEM.1')
  ...
  oBiometric:SetCommPassword( 'password' )                           //this is important if you set communication password to your biometric device
  ...
 
  IF ( lGo := oBiometric:Connect_Net( 'ip address', 'port' ) )

      IF !oBiometric:IsTFTMachine( 'device_id' )                         //you set this nID in your device, important if you have many devices. this is numeric
          MsgAlert('non-TFT Device..', 'COMPATIBILITY ISSUE')
      ENDIF

      ...

      oBiometric:RefreshData( 'device_id' )                                //some commands you may want to use  

      ...

      IF oBiometric:ReadGeneralLogData( 'device_id' )

                j := 0

                WHILE oBiometric:SSR_GetGeneralLogData( 'device_id',,,,,,,,,,)  //this is the only way I know how to get number of records from the device.
                      j++                                                                                     //if you know a better way please share.
                END

                oBiometric:ReadGeneralLogData(  'device_id' )                            //get ready and position 1st record pointer

               //this is how I get every record
                WHILE oBiometric:SSR_GetGeneralLogData('device_id', @cEnrollID, @nVerifyMO, @nInOutMO, @nYearOUT, @nMoOUT, @nDayOUT, @nHrOUT,  
                                                                                 @nMinOUT, @nSecOUT, @nWorkOUT )

                           ...
                       
                           //work your way here how to process those data

                END

        ENDIF

  ELSE

       nError := 0
       oBiometric:GetLastError(@nError)
       msginfo( nError )  

 ENDIF

 

Please share if you have better ways or faster ways to get all those data.
I hope this helps.

Lucas,

I haven't tried this to other devices. Model I use is FS-800u "Time and attendance terminal" made is China.
I use the .dll from devices CD.

Esta librería (zkemkeeper.dll) funciona con lectoras USB?

Lo digo porque estoy tratando de implementar una Digital Persona 4500 y no lo consigo.
