Hi,

Could you provide more details on your issue? Have you modified the sample source code?
You mentioned that you have created default database. How was it done?
It could be a situation that database is corrupted. So could you try to delete FingerprintDB.vb6.dat and UserDB.vb6.dat files from bin folder?
Best regards,

Hi,

It is very hard to say what are you doing wrong. The easiest way to find where is the problem is to debug an application step by step.

Hello Bayu,

Is the scanner recognized by Neurotechnology samples/tutorials? Please contact support@neurotechnology.com and specify all the details on problem your are facing.

FreeFingerprintSDK Error: Unable to load Nffv.dll

Postby craigtfromatl » Jul 28, 2010 21:24

I've been having some trouble getting the free fingerprint sdk integrated with an existing application. I am able to run the samples w/out getting this error, but continue to receive this error when I utilize the code in an existing winforms app. (.NET)

I'm getting this error:
Unable to load DLL 'Nffv.dll': The specified module could not be found. (Exception from HRESULT: 0x8007007E)

from this line of code:
engine = new Neurotec.Biometrics.Nffv(FingerPrintUtilities.GetDatabase(), string.Empty, "Upek");

"FingerprintUtilities" is a class I created to handle some of the basic utilities such as returning the path to the the text file that acts as the database. So "GetDatabase()" returns a string.

"engine" is defined in the class as: "public Neurotec.Biometrics.Nffv engine;"

The "Neurotec.Biometrics.Nffv.dll" DLL is present and is referenced. For giggles, I found the "Nffv.dll" dll and referenced it, but I then received errors about the licensing service not running. I'd like to use the free version as it more than accomplishes what we're trying to do.

Any ideas off the top of your head as to why I may be receiving this error or how I can get more detailed information on why I'm receiving this error?

Thanks!
Craig

Hello Craig,

You should have Neurotec.Biometrics.Nffv.dll, Nffv.dll and NffvServer.exe for application your are developing, The best way is to put them to the same directory where your application's executable is. In our SDK, the required files and executable application are in "FreeFingerprintVerificationSDK\bin\Win32_x86" directory.

Hello,

please check if the Nffv.dll is loaded with your application. Neurotec.Biometrics.Nffv.dll depends on the Nffv.dll. The best solution in this case is to copy all dlls from the SDK folder to your application output folder.

Hello,

Free Fingerprint Verification SDK can use only its proprietary database. If you need to use any other database then you need to consider VeriFinger 6.2 SDK usage.

Hello,

Free Fingerprint Verification SDK does not allow to save the scanned image. Also it has limitations on the size of the database. You can consider usage of the VeriFinger 6.2 Standard SDK, which will allow you to save scanned images and have unlimited database. This SDK includes samples and tutorials, which allows customer to see how everything can be implemented.

Hello,

FFV SDK is intended to be used only on systems where maximum 10 fingerprints will be enrolled. It is a limitation of this SDK. If you need to enroll more users then consider VeriFinger 6.3 SDK usage. Comaprison between FFV SDK and VeriFinger SDK can be found here.

Hello,

FFV SDK engine saves only numeric ids. So you should save the name of users and related ids in the separate database or file. So before enrolling you can check if such name exists in the database. C# uses the xml as the database for user names keeping. So you can search it and compare names.

You need to specify the java.library.path when executing. i.e. java -Djava.library.path=PATH_TO_NffvJavaNative.dll -jar NffvSample.jar.
Also you can specify the path to NffvJavaNative.dll in the PATH environmental variable too.

Hello,

please check if the Nffv.dll is loaded with your application. Neurotec.Biometrics.Nffv.dll depends on the Nffv.dll. The best solution in this case is to copy all dlls from the SDK folder to your application output folder.


I am having the same problem above, but if I copy the dlls from the sdk folder, the problem still continues. However, I am using VS 2008, and I only have bin folder.

How do I load nffv.dll with my VStudio 2008 application?
Thanks

Hello,

Free Fingerprint Verification SDK does not provide support of the standard templates (ISO or ANSI). If the support of standard templates is needed, then the Fingerprint BSS component is required; the component is available in VeriFinger Extended SDK or MegaMatcher SDK.

How I can to implement ANSI/NIST-ITL 1-2000 (ANTemplate) in FreeFingerprintVerificationSDK??
The result Fingerprint database file (.dat) doesn´t have this standard.
I'm working whith the c# example.

Thank you,

Hello,

Free Fingerprint Verification SDK does not provide support of the standard templates (ISO or ANSI). If the support of standard templates is needed, then the Fingerprint BSS component is required; the component is available in VeriFinger Extended SDK or MegaMatcher SDK.

Hello,

The BSS component is available only in the VeriFinger Extended and MegaMatcher SDKs.
It is not possible to use it with the Free Fingerprint Verification SDK.

The BSS component can be tested with trial versions of VeriFinger or MegaMatcher SDK.
