Can someone help me to translate this visual class to some i

Posted by OctavioOlguin on 18-Feb-2017 09:16

This is a visual class.. but I would like to get off all visuals, and encapsulate this functionatily on class that I instantiate, and call it method and get a tt back?   Just starting to get into OO..  Thnaks.

What are you actually struggling with?
 
Did you try to move the methods btnStart_Click, msgError and ByteArrayToMemptr to a class? btnStart_Click does all the actual work and needs to be PUBLIC then.
 
What you need to obtain from the documentation of the UFScannerManager class is, if it’s required to pass a System.Windows.Forms.Form instance (THIS-OBJECT here) to the constructor or not.
 
A warning:
 
                CREATE tt1.
                ASSIGN
                    tt1.f1 = ByteArrayToMemptr(template).
                COPY-LOB FROM OBJECT f1 TO FILE "e:\t\fingerprint.dat".    // aqui tenemos el template
The method ByteArrayToMemptr returns a MEMPTR which you never set back to 0 – so you never give back the memory allocated.
 
DEFINE VARIABLE mptr AS MEMPTR NO-UNDO .
mptr = ByteArrayToMemptr(template).
COPY-LOB FROM mptr TO FILE “e:\t\fingerprint.dat” .
SET-SIZE (mptr) = 0 .

This is a visual class.. but I would like to get off all visuals, and encapsulate this functionatily on class that I instantiate, and call it method and get a tt back?   Just starting to get into OO..  Thnaks.

You nailed!!!


That's exactly my problem.... I don't know how to resolve that problem... this is doc: from class:




// Add Suprema UFScanner library (bin\Suprema.UFScanner.dll)
using browse tap in the Add References dialog
// Add following statements in the source
using Suprema
// We use 384 bytes template size in this tutorial
const int MAX_TEMPLATE_SIZE = 384;
UFS_STATUS ufs_res;

UFScannerManager ScannerManager;
int nScannerNumber;

// Create an instance of ScannerManager
ScannerManager = new UFScannerManager(this);

// Initialize scanner module
ufs_res = ScannerManager.Init();
// Always check status return codes after running SDK
functions
// Meaning of status return code can be retrieved using
UFScanner.GetErrorString()
// In the tutorial, we omit error check codes
// Check number of scanners
nScannerNumber = ScannerManager.Scanners.Count;

UFScanner Scanner = null;
// Using first scanner (0 means first scanner)
Scanner = ScannerManager.Scanners[0];

Scanner.Timeout = 5000;
// Set template size to 384 bytes
Scanner.TemplateSize = MAX_TEMPLATE_SIZE;
// Set not to detect core when extracting template
Scanner.DetectCore = false;

UFS_STATUS ufs_res;
byte[] Template = new byte[MAX_TEMPLATE_SIZE];
int TemplateSize;

int EnrollQuality;
// Clear capture buffer
ufs_res = Scanner.ClearCaptureImageBuffer();
// Capture single image
ufs_res = Scanner.CaptureSingleImage();
// If capturing images is fail, iterate above capture
routine or show error message
// Extract template from captured image
ufs_res = Scanner.Extract(Template, out TemplateSize, out
EnrollQuality);
// If extraction is succeed, check nEnrollQuality is above
predefined quality threshold

UFS_STATUS ufs_res;
// Uninitialize scanner module
ufs_res = ScannerManager.Uninit();

It is not you can say it is a good doc. But that's all there is for aquiring a template

They might need a reference to a Control for thread synchronization (background thread to UI thread).


 


But that does not prevent you from changing your code, so that it’s a class with no UI. You will just have to provide your class a reference
 to a Form instance (the application’s main menu form) and pass that on to the constructor of that UFScannerManager.

As I'm  behind schedule, I'll preserve the little class form with a button just to process, but how could end the class from the button, to return control toa UIB window?


also, I copyed the runtime code by the PDSOE to tun the form, and ended with this:

From within the Form class, just execute THIS-OBJECT:Close ().
