How to verify a fingerprint from MySQL database in seperated form. (VB.NET)

Leetian04 asked:

Open original thread
These are codes in verifying a fingerprint, but not using MySQL database. I want it to compare a fingerprint scanned to database. If matched then These codes are from the SDK of the Biometric Digital Persona (U.are.U 4500).

' NOTE: This form is inherited from the CaptureForm,
' so the VisualStudio Form Designer may not load this properly
' (at least until you build the project).
' If you want to make changes in the form layout - do it in the base CaptureForm.
' All changes in the CaptureForm will be reflected in all derived forms 
' (i.e. in the EnrollmentForm and in the VerificationForm)

Public Class VerificationForm
  Inherits CaptureForm

  Private Template As DPFP.Template
  Private Verificator As DPFP.Verification.Verification

  Public Sub Verify(ByVal template As DPFP.Template)
    Me.Template = template
  End Sub

  Protected Overrides Sub Init()
    MyBase.Text = "Fingerprint Verification"
    Verificator = New DPFP.Verification.Verification()
  End Sub

  Protected Overrides Sub Process(ByVal Sample As DPFP.Sample)

    ' Process the sample and create a feature set for the enrollment purpose.
    Dim features As DPFP.FeatureSet = ExtractFeatures(Sample, DPFP.Processing.DataPurpose.Verification)

    ' Check quality of the sample and start verification if it's good
    If Not features Is Nothing Then
      ' Compare the feature set with our template
      Dim result As DPFP.Verification.Verification.Result = New DPFP.Verification.Verification.Result()
      Verificator.Verify(features, Template, result)
      If result.Verified Then
        MakeReport("The fingerprint was VERIFIED.")
        MakeReport("The fingerprint was NOT VERIFIED.")
      End If
    End If
  End Sub

  Protected Sub UpdateStatus(ByVal FAR As Integer)
    ' Show "False accept rate" value
    SetStatus(String.Format("False Accept Rate (FAR) = {0}", FAR))
  End Sub

    Private Sub VerificationForm_Load(sender As Object, e As EventArgs) Handles MyBase.Load

    End Sub
    Private Sub InitializeComponent()
        Me.AutoScaleDimensions = New System.Drawing.SizeF(6.0!, 13.0!)
        Me.ClientSize = New System.Drawing.Size(581, 354)
        Me.Name = "VerificationForm"

    End Sub
End Class
