    Smile Help me to convert in to byte.....

    hi friends. i'm currently doing an assignment which is based on vb.net and sql server. here i wanna capture an image and i wanna save that into a sql table named 'customer'. i have downloaded the code for capture the image from the webcam and store into local hard drive. (http://www.vb-helper.com/HowTo/howto...eo_capture.zip)

    When i click the save button in that app, its showing to save the captured image in a place by giving a name.

    '-----------------------------------------------------------------
    Private Sub btnSave_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSave.Click
    Dim data As IDataObject
    Dim bmap As Image

    data = Clipboard.GetDataObject()
    If data.GetDataPresent(GetType(System.Drawing.Bitmap)) Then
    bmap = CType(data.GetData(GetType(System.Drawing.Bitmap)), Image)
    picCapture.Image = bmap

    ClosePreviewWindow()
    btnSave.Enabled = False
    btnStop.Enabled = False
    btnStart.Enabled = True

    If sfdImage.ShowDialog = DialogResult.OK Then
    bmap.Save(sfdImage.FileName, Imaging.ImageFormat.Bmp)
    End If

    End If
    End Sub
    '--------------------------------------------------------------------

    in the above code in red colored area, u can see variable bmap is holding captured image and i wanna pass that 'bmap' to sql table.

    pls help me...........thanks in advance

    First up, your clipboard code is way more complex than is necessary:
    vb.net Code:
    1. If Clipboard.ContainsImage() Then
    2.     Dim img As Image = Clipboard.GetImage()
    3.  
    4.     '...
    5. End If
    As for saving the Image to SQL Server, I have posted a thread in the VB.NET CodeBank submission that shows how to do just that. Follow the CodeBank link in my signature to find that thread.
