FingerPrint capturing from DLL-file is not initiating

Hi, I have a problem initiating a fingerprint DLL I am testing.

The program is called Griaule, with the DLL + lib GrFinger

I am starting slowly, so the only thing I want to do is to open a bmp-file that I have in the computer, that contains a fingerprint. Then I would like GrFinger to calculate the template of the finger, that is the "thing" that it can use to recognize the finger if I will open another picture, if of course I save this template somewhere, but that is not the problem yet.

my problem is to get the Capeturing initiated

according to: "GrFinger 4.1 DLL Developer's Manual ENUS.pdf"
that can be downloaded with the free version of GeFinger from:
http://www.griaule.com/page/en-us/downloads

To open a fingerprint, is the same as to capture it from a finger-sensor, so I want to initiate the capturing, but I can't make it work, I either get "access violation", or I can't compile because the parametres of GrCapInitialize() is wrong... how do I create the StatusEventHandler, so the fallowing will work:

retVal= GrCapInitialize (StatusEventHandler);

unfortunaly I am using plain old microsoft visual c++ 6.0, so I can't get the c++.Net examples that they deliver to work.


my code looks like this until now, but it doesn't work

in the h-file:
    // Callbacks
    GRCAP_STATUS_EVENT_PROC *myCallBack;
    GRCAP_FINGER_EVENT_PROC *myFingerCallBack;
    GRCAP_IMAGE_EVENT_PROC *myImageCallBack;


in the cpp-file

    // stuff that needs to be started before the fingerprint recognition can start.

    //Initialize the library
    result = GrInitialize();

    retVal = GrCapInitialize (&CTrainingDlg::StatusEventHandler("File", myCallBack));

    // Start capturing from the plugged sensor.
    startCapVal = GrCapStartCapture("File", myFingerCallBack, myImageCallBack);
   
    // this opens the open file dialog window
    if(m_openFile->DoModal() == IDOK)
    {
        char temp[100];
        strcpy (temp, m_openFile->GetPathName());

        ImageLoaded = GrCapLoadImageFromFile( temp, resolution );
       
        if (ImageLoaded != GR_OK)
        {
            AfxMessageBox("Can't open file");
        }
    }

and I do have the GrFinger.lib included in my project, so I dont think that is the problem, also because result = GrInitialize(); is working fine, and it gives the right result.

I would be very happy to get some help on this problem, thanks.

Best regards
