Lab 1: Biometrics (Finger Print Enrollment)

Objective : To allow students to make use of the futronic SDK(Soft ware development kit) to program a GUI(Graphic User Interface) to allow enrollment of finger print of the user into the database.

Items required for the lab:1. ftrSDKHelper8.dll2. DbRecord.cs3. EnrollmentName.cs4. Finger print scanner5. C# visual Studio 20086. PC with Windows OS

The program developed will be used for all subsequent Job Sheets.

Students are to save their programs and keep them safe.

Lab 1

Step 8d. Coding for GetDatabaseDir() function.

Step 8e. At the solution explorer, double click on the Form1.cs


/// <summary> /// Get the database directory. /// </summary> /// <returns>returns the database directory.</returns>

public static String GetDatabaseDir() { String szDbDir; szDbDir = Path.Combine(Directory.GetCurrentDirectory(), "Database");

//Create the directory of the database at the Bin folder of the program. if (!Directory.Exists(szDbDir)) { Directory.CreateDirectory(szDbDir);

//Create the directory of the database at the Bin folder }

return szDbDir; }

Double click on the Form1.cs

Lab 1

Step 8f. Double click on the enroll button to type the coding for enrollment.

Step 8g. Type the coding onto the indicated field.


Double click on the Enroll button to doing program the Enroll button.

FingerPrint1.BackgroundImage = null;FingerPrint2.BackgroundImage = null;FingerPrint3.BackgroundImage = null; DbRecord User = new DbRecord(); // Get user name EnrollmentName frmName = new EnrollmentName(); frmName.ShowDialog( this ); if (frmName.DialogResult != DialogResult.OK ) { return; } if( frmName.UserName.Length == 0) { MessageBox.Show( this, "You must enter a username.", this.Text, MessageBoxButtons.OK, MessageBoxIcon.Exclamation ); return; } // Try creat the file for user's information if( isUserExists(frmName.UserName) ) { DialogResult nResponse; nResponse = MessageBox.Show("User already exists. Do you want replace it?", "C# example for Futronic SDK", MessageBoxButtons.YesNo, MessageBoxIcon.Question);

if (nResponse == DialogResult.No) return; }

Lab 1

Step 8h. Program the function isUserExists, EnableControls, OnPutOn, SetStatusText,


else { try { CreateFile(frmName.UserName); } catch (DirectoryNotFoundException) {

MessageBox.Show(this, "Can not create file to save an user's information.", this.Text, MessageBoxButtons.OK, MessageBoxIcon.Exclamation);

private void OnTakeOff(FTR_PROGRESS Progress){

this.SetStatusText("Remove thumb/finger from device");}

private void UpdateScreenImage(Bitmap hBitmap){

// Do not change the state control during application closing.

private bool OnFakeSource(FTR_PROGRESS Progress){

if( m_bExit )return true;

DialogResult result;result = MessageBox.Show("Fake source detected. Do you want continue process?",

"C# example for Futronic SDK",MessageBoxButtons.YesNo, MessageBoxIcon.Question

Lab 1

Step 8h. On solution explorer double click on the Form1.cs.


private bool OnFakeSource(FTR_PROGRESS Progress){

if( m_bExit )return true;

DialogResult result;result = MessageBox.Show("Fake source detected. Do you want continue process?",

"C# example for Futronic SDK",MessageBoxButtons.YesNo, MessageBoxIcon.Question

Lab 1

Step 8i. Double click on the Stop button.

Step 8j. Coding for the Stop button.

Step 8k, Double click on the Form1.cs in solution explorer.

Step 8l Double click on the Exit button.



Double click on the Stop button

m_Operation.OnCalcel();


Lab 1

Step 8m Programming for the Exit button.

Step 9. Build the solution by keying F5, and run debug by pressing F6.

Step 10: When there is no error, test your program with the Finger Print Scanner.

Step 11: Save your project.

Conclusion


Double click on the Exit button

base.Hide();m_bExit = true;this.Close();

Lab 1

1. State what these program codes do

codes What they doSetStatusText(“Hello”)

Close()

String szFileName; szFileName = Path.Combine(m_DatabaseDir, UserName); File.Create(szFileName).Close(); File.Delete(szFileName);

FingerPrint1.BackgroundImage = null;

MessageBox.Show(“Welcome”)

szDbDir = Path.Combine(Directory.GetCurrentDirectory(), "Database");

szMessage.Append("Enrollment process failed.");szMessage.Append("Error description: ");

2. State 2 problems faced when trying to enroll fingerprint.
