Hi Everybody,

I am tinkering with a fingerprint scanner ActiveX control (Digital Persona).

Instantiating, dropping and working with it seems to go on smoothly... till the last event called Done(), where it passes a "Fingerprint Template - FPTemplate" object variable.

This is the code I created in the ActiveX control's Done() event:

*** ActiveX Control Event ***
LPARAMETERS ptemplate

LOCAL lblobFingerPrnt, lnResult

WAIT WINDOW NOWAIT "Creating Employee Record..." NOCLEAR

lnResult = ptemplate.Export( @lblobFingerPrnt )

IF lnResult # Er_OK
   MESSAGEBOX( "Error in getting Registration Template" )
   RETURN
ENDIF

APPEND BLANK IN employee
replace employee.lastname WITH thisform.txtLastname.Value,;
        employee.firstname WITH thisform.txtFirstname.Value,;
        employee.fingerprnt WITH lblobFingerPrnt

WAIT CLEAR

I get "Data type mismatch" using the above. Going thru the Debugger, the value of variable lblobFingerPrnt is always .F. and is never updated even when invoking the Export method.

This 'ptemplate' object variable, as per it's documentation, has an Export method, like so:

Export([out] VARIANT* pVal, [out,retval] AIErrors *pErr)

* Exports the template object as a signed blob of bytes.
* This may then be saved by the developer in the database of his choice.

HELP! Obviously it has something to do with a VARIANT data type. Furthermore, the employee.fingerprnt field is of Blob type. Could this be wrong?

Thanks in advance!

Happy Holidays! Cheers!
