gaano ka laki ang mga images, at ilang records ang niloload mo sa showrecord()? gumawa ka ng additional column sa table mo, thumbnail, e resize mo ang original image nung pag save para sa thumbnail, during showrecord, thumbnail lang ang kunin mo, wag mo kunin ang buong picture, pag click, dun mo na event ilagay ang pagkuha ng full size image para mas mabilis mag load ang showrecord

TS! thanks sa idea mo nagawa ko na siya bale sa upon saving yung path nung picture/s sinasave ko then pag dating sa form masterfile hinide ko yung path(texbox) then naglagay nalang ako ng button na VIEW PHOTO mabilis na mag load ngayon yung masterfile ko. Thanks ulit sa idea :)

may unting problema yung approach na yan. pag na wala ang image or na delete ang image, di na mag loload, dapat kunin nya sa pa rin from db ang image.

mga master pa help naman po dito sa code ko

Dim resultConversion As DataResult(Of Fmd) = FeatureExtraction.CreateFmdFromFid(captureResult.Data, Formats.Fmd.ANSI)

If resultConversion.ResultCode <> Constants.ResultCode.DP_SUCCESS Then
_sender.Reset = True
Throw New Exception("" & resultConversion.ResultCode.ToString())
End If

If count = 0 Then
rightIndex = resultConversion.Data
count += 1
SendMessage(Action.SendMessage, "Now place your finger on the reader.")
ElseIf count = 1 Then
rightThumb = resultConversion.Data
count += 1
SendMessage(Action.SendMessage, "Now place your finger on the reader.")
ElseIf count = 2 Then
Dim fingerprint = Fmd.SerializeXml(resultConversion.Data)
anyFinger = resultConversion.Data
Dim fmds(1) As Fmd
fmds(0) = rightIndex
fmds(1) = rightThumb

' See the SDK documentation for an explanation on threshold scores.
Dim thresholdScore As Integer = DPFJ_PROBABILITY_ONE * 1 / 100000

Dim SqlQuery = "SELECT fingerprin From tb_workers"
objcmd = New MySqlCommand(SqlQuery, objconn)
objdr = objcmd.ExecuteReader

While objdr.Read
Dim dbprints = objdr.GetString("fingerprint")
Dim X = Fmd.DeserializeXml(dbprints)
Dim Y = Fmd.SerializeXml(X)

Dim identifyResult = Comparison.Identify(X, 0, fmds, thresholdScore, 2)

If identifyResult.ResultCode <> Constants.ResultCode.DP_SUCCESS Then
_sender.Reset = True
Throw New Exception("" & identifyResult.ResultCode.ToString())
End If

SendMessage(Action.SendMessage, "Identification resulted in the following number of matches: " & identifyResult.Indexes.Length.ToString())
count = 0
End While
objcmd.Dispose()
objdr.Close()

End If

im trying to compare results of scanned fingerprints from my database.
yung last na row lang na read ng while statement ko dun lang nag mamatch yung mga prev prints d nag mamatch
mali ata looping ko patulong namn.
salamat po

save to db

Code: 
Dim connection As New SqlConnection("connection string here")
Dim command As New SqlCommand("UPDATE MyTable SET Picture = @Picture WHERE ID = 1", connection)

'Create an Image object.'
Using picture As Image = Image.FromFile("file path here")
    'Create an empty stream in memory.'
    Using stream As New IO.MemoryStream
        'Fill the stream with the binary data from the Image.'
        picture.Save(stream, Imaging.ImageFormat.Jpeg)

        'Get an array of Bytes from the stream and assign to the parameter.'
        command.Parameters.Add("@Picture", SqlDbType.VarBinary).Value = stream.GetBuffer()
    End Using
End Using

connection.Open()
command.ExecuteNonQuery()
connection.Close()

retrieve

Code: 
Dim connection As New SqlConnection("connection string here")
Dim command As New SqlCommand("SELECT Picture FROM MyTable WHERE ID = 1", connection)

connection.Open()

Dim pictureData As Byte() = DirectCast(command.ExecuteScalar(), Byte())

connection.Close()

Dim picture As Image = Nothing

'Create a stream in memory containing the bytes that comprise the image.'
Using stream As New IO.MemoryStream(pictureData)
    'Read the stream and create an Image object from the data.'
    picture = Image.FromStream(stream)
End Using

Thank you TS! subukan ko itong solution mo :) last na TS! my question ako isa pa ano po mali dito sa code ko? ang ginagawa ko po kasi is sa datagridview once na expired na yung contract nag hihighlight siya ng red then white pag active pa yung contract also nag set din ako ng notifications sa system tray ngayon ang nangyayari is parang ndi na susunod yung condition na ginawa ko dun sa datagridview below is yung code na ginamit ko:

View attachment 303825

Private Sub EXPIREDCONTRACT_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Try
showrecexpired()
Dim x As Integer

For Each row As DataGridViewRow In DGExpired.Rows
If Not row.IsNewRow Then
If Date.Now.ToString("MM/dd/yyyy") >= row.Cells(18).Value Then
x = 1
row.DefaultCellStyle.BackColor = Color.Red
row.DefaultCellStyle.ForeColor = Color.White
End If
End If
Next

If x = 1 Then
NotifyIcon1.BalloonTipText = "You have an expired document!"
NotifyIcon1.Text = "Expired Document"
NotifyIcon1.ShowBalloonTip(500)
CreateContextMenu()
x = 0
End If
Catch ex As Exception

End Try
End Sub
