Hello all,

I have an app for attendance control that uses MS Fingerprint Reader,
unfortunately this device is no longer manufactured by MS an I am looking
for a replacement. I am evaluating a Digital Persona U.are.U 4500
Fingerprint Reader but trouble arises when trying to create a class from the
DPFPDevX.dll file provided with the SDK. I can create an instance with
CreateObject("DPFPDevX.DPFPCapture") but can't override the methods of the
instance to write custom code. I would like to create a class based on the
SDK implementation but error 1733 (Class definition DPFPCAPTURE is not
found) arises. My testing code is:

Define Class clsCapt As DPFPCapture Of DPFPDevX.dll

Procedure IDPFPCapture_StartCapture()
Endproc
Procedure IDPFPCapture_StopCapture()
Endproc
Procedure IDPFPCapture_get_ReaderSerialNumber()
Endproc
Procedure IDPFPCapture_put_ReaderSerialNumber(SerialNumber As
String)
Endproc
Procedure IDPFPCapture_get_Priority()
Endproc
Procedure IDPFPCapture_put_Priority(Priority As Integer)
Endproc
Procedure OnComplete(ReaderSerNum As String, pSample As Object)
Messagebox("El n�mero de serie del lector es: " +
ReaderSerNum)
Endproc

Enddefine

I will really appretiate any help.

TIA

Hi Carlos,

I've been trying to use the same SDK and experienced similar problems. The code you have should work. Just check and ensure all the required dlls have been registered and create the object for the defined class after the class definition. Hope this is helpful, but I expect you have already solved you problem by now.
