Hi
I'm trying to get the 'Uploadify' upload progress plugin working with an existing asp/vb.net site that uploads pictures to a database.

The existing site uses an asp.fileupload component and the upload action is via a separate upload button. All code for this is in the asp forms aspx.vb file.


Ok, I've got the gui side of things sorted but I'm not sure how to get uploadify to fire the existing btnUpload_Click event.
Presumably teh problem is with directing the 'uploader' variable. I see a lot of people utilising generic handler ashx routines but I have no idea how to move my btnUpload code to this and retain all the form input info.
Can someone advise me on how to deal with this problem?

I have this code in the pages HEAD section:
JavaScript
<link href="~/Styles/uploadify.css" rel="stylesheet" type="text/css" />
<script type="text/javascript" src="http://code.jquery.com/jquery-1.10.2.min.js"></script>
<script type="text/javascript" src="Uploadify/jquery.uploadify.min.js"></script>

<script type="text/javascript">
$(function() {
    $("#<%=fupImage.ClientID %>").uploadify({
        'swf'       : 'Uploadify/uploadify.swf',
        'uploader'  : 'uploadify.php',
        'buttonText': 'Select Image',
        'cancelImg' : 'images/uploadify-cancel.png',
        'folder'    : 'uploads',
        'fileDesc'  : 'Image Files',
        'fileExt'  : 'Image Files (.JPG, .JPEG, .GIF, .BMP, .PNG)',
        'sizeLimit' : 4000000,
        'auto'      : false,
        'multi'     : false
    });
});
</script>


and here's my btnUpload code:
VB
Protected Sub btnUpload_Click(sender As Object, e As EventArgs) Handles btnUpload.Click
    pnlConfirmation.Visible = False
    lblUploadResult.Text = ""
    lblUploadResult.ForeColor = Color.DarkGreen

    'validate all fields before uploading
    If Not validateControls() Then
        lblUploadResult.Text += vbCrLf + "Try again."
        lblUploadResult.ForeColor = Color.Red
        pnlConfirmation.Visible = True
        Exit Sub
    End If

    'check for any other entries by this person
    If checkOtherEntries() Then
        lblUploadResult.Text = "There is already an entry for this email address." + vbCrLf + _
                               "If you feel this is an error then please email" + vbCrLf + _
                               appConfiguration.ErrorLogEmail
        lblUploadResult.ForeColor = Color.Red
        pnlConfirmation.Visible = True
        Exit Sub
    End If

    '**All validated so allow the upload

    'check to make sure a file is selected before adding it to the db
