Consulta base de datos con lector de huella

[Melecio]

Hola a todos

tengo un lector de huella Uare U digital persona 4500.

Logre hacer que funcione correctamente el detalle es que mi bd cuenta con 300 registros y al tratar de buscar de uno por uno se tarda mas de 3 segundos en identificarme la huella

Codigo
Public a(1632) As Byte
Public huella(9999) As String
Public NOMBRE(9999) As String
Public NUMERO_OPERADOR(9999) As String

Public ARREGLO As Integer

Public strsqlmsql As String
Public mysqlconn As New MySqlConnection
Public mysqlcmd As New MySqlCommand
Public mysqldr As MySqlDataReader
Public mysqlda As New MySqlDataAdapter



EN FORM LOAD

Private Sub VerificationForm_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
mysqlconn.ConnectionString = "server=localost; user id=root; password =; database = finger;"

Try
mysqlconn.Open()
strsqlmsql = " SELECT DISTINCT finger1,num_operador,nombre FROM general_empleados WHERE estatus ='ALTA' ORDER BY id_operador DESC "
mysqlcmd.CommandText = strsqlmsql
mysqlcmd.Connection = mysqlconn
mysqlda.SelectCommand = mysqlcmd
mysqldr = mysqlcmd.ExecuteReader
While (mysqldr.Read())
huella(ARREGLO) = mysqldr("finger1")
NUMERO_OPERADOR(ARREGLO) = mysqldr("num_operador")
NOMBRE(ARREGLO) = mysqldr("nombre")

ARREGLO += 1

End While
mysqlcmd.Dispose()
mysqldr.Close()
mysqlconn.Close()
Catch ex As Exception
End Try

mysqlconn.Close()
End Sub







VERIFICACION DE HUELLA






Sub OnComplete(ByVal Control As Object, ByVal FeatureSet As DPFP.FeatureSet, ByRef EventHandlerStatus As DPFP.Gui.EventHandlerStatus) Handles VerificationControl.OnComplete
Dim ver As New DPFP.Verification.Verification()
Dim res As New DPFP.Verification.Verification.Result()
Dim temp = New DPFP.Template()





Dim i As Integer
For i = 0 To ARREGLO

Try
a = Convert.FromBase64String(huella(Str(i)))
temp.DeSerialize(a)
ver.Verify(FeatureSet, temp, res)

Data.IsFeatureSetMatched = res.Verified
Data.FalseAcceptRate = res.FARAchieved


If res.Verified Then
EventHandlerStatus = DPFP.Gui.EventHandlerStatus.Success
LBL_HORA.ForeColor = Color.Green
LBL_DIA.ForeColor = Color.Green
LBL_NOMBRE_PERSONAL.ForeColor = Color.Green
IMAGEN_FOTO.BackColor = Color.Green


IMAGEN_PERSONAL.ImageLocation = "C:\FOTOGRAFIAS\" & NUMERO_OPERADOR(i) & ".jpg"
LBL_NOMBRE_PERSONAL.Text = i
CONTEO.Enabled = True
GoTo SALIDA


End If
If Not res.Verified Then EventHandlerStatus = DPFP.Gui.EventHandlerStatus.Failure

Data.Update()




Catch ex As Exception

End Try
