hi all,
I have code like this in a windows application that displays bytes of array in a picture box. This codes are in VB.
Dim UserPassport As Passport = New Passport()
m_OperationObj = UserPassport
' Get user name
Dim frmName As EnrollmentName = New EnrollmentName()
frmName.ShowDialog(Me)
If frmName.DialogResult <> System.Windows.Forms.DialogResult.OK Then
Return
End If
If frmName.UserName.Length = 0 Then
MessageBox.Show(Me, "You must enter a user name.", Me.Text, MessageBoxButtons.OK, MessageBoxIcon.Exclamation)
Return
End If
UserPassport.UserName = frmName.UserName
m_Operation = New FutronicEnrollment()
' Set control properties
m_Operation.FakeDetection = chDetectFakeFinger.Checked
m_Operation.FFDControl = True
m_Operation.FARN = Int32.Parse(tbFARN.Text)
CType(m_Operation, FutronicEnrollment).MIOTControl = cbMIOT.Checked
CType(m_Operation, FutronicEnrollment).MaxModels = Int32.Parse(CType(cbMaxFrames.SelectedItem, String))
EnableControls(False)
' register events
AddHandler m_Operation.OnPutOn, AddressOf OnPutOn
AddHandler m_Operation.OnTakeOff, AddressOf OnTakeOff
AddHandler m_Operation.UpdateScreenImage, AddressOf UpdateScreenImage
AddHandler m_Operation.OnFakeSource, AddressOf OnFakeSource
AddHandler (CType(m_Operation, FutronicEnrollment)).OnEnrollmentComplete, AddressOf OnEnrollmentComplete
' start enrollment process
CType(m_Operation, FutronicEnrollment).Enrollment()
Now i need to work it out in a web form where i shld display the bytes of array generated in a image control in web app.
Basically my application is a finger print scanner. When i click on Enroll button the image captured shld be displayed in a web form.
Anyone can help me out?

So the bytes array is coming from ... where? The fingerprint scanner?
Is it a fact or an assumption that the byte array output from the fingerprint scanner is actually an image? Seems unlikely to me that a fingerprint scanner is really just a tiny flatbed image scanner.
If it were just the image of a fingerprint then every developer using one would be responsible for analysing the image.
Maybe the scanner output is the result of internal computation turning the complex image into a code that represents that fingerprint. Thus giving uniform functionality to all programs without each one having to design their own fingerprint analysis routine.
Also, if you scan a fingerprint for security do you really *want* to display that scanned image on screen? Seems like a hole in the security. Maybe you should just use the code it gives you for your security needs, and display a generic fingerprint.png as feedback that the print was successfully scanned.
hey Friends,
I want a simple help from you,
I want a code that how to catch event of finger put on machine and how to catch the signal(message) from fingerprint machine (Like finger is valid or not)
I have a code to connect with fingerprint device as below
int count = 0;
zkemkeeper.CZKEMClass axczkem1 = new zkemkeeper.CZKEMClass();
bool bIsConnected = false;
string ip = "192.168.1.170";//write here IP Address of your biomatric m/c
int port = 4370;
bIsConnected = axczkem1.Connect_Net(ip, port);
if (bIsConnected == true)
{
Label1.Text = "Connection established!!!";
bool ret = axczkem1.ReadAllGLogData(1);
if (ret)
{
int a = 0;
int b = 0;
int c = 0;
int d = 0;
int ee = 0;
int f = 0;
int g = 0;
int h = 0;
int i = 0;
int j = 0;
int k = 0;
int l = 0;
int m = 0;
int n = 0;
int o = 0;
while (axczkem1.GetAllGLogData(1, ref a, ref b, ref c, ref k, ref l, ref d, ref m, ref ee, ref f, ref g))
{
//if (ee == 7 && m == 4 && d == 2011)
{
count++;
//if (b == //any Employee No)
//{
Label1.Text = b.ToString() + " hour: " + f + " Min: " + g;
//Label1.Text=k.ToString() + " " + l.ToString();
//}
}
}
//MessageBox.Show(count.ToString ());
}
}
else
Label1.Text = "cannot Connection!!!";
axczkem1.Disconnect();
But i dont know how to implement further,
Please any one help me
The connection is establish successfully but i dont know about other events like finger putting on machine,catch message sent by machine
Thanks
