Hi everyone,

Here is another epic fail while trying to implement uploadify using .NET. Basically, uploadify displays the HTTP error 500 and I don't know why.

Here is my code:

Defautl.aspx:

In the head

<script type="text/javascript" src="http://code.jquery.com/jquery-1.7.2.min.js"></script&gt;
<script type="text/javascript" src="/uploadify/jquery.uploadify-3.1.js"></script>
<script type = "text/javascript">
$(function () {
$('#<%=FileUpload1.ClientID %>').uploadify({
'swf': 'uploadify/uploadify.swf',
'uploader': 'uploadify/uploadify.ashx',
'checkExisting': 'uploadify/check-exists.ashx',
'fileObjName': 'Filedata',
'debug': 'true',
'folder': 'uploads',
'onUploadStart': function (file) {
alert('Starting to upload ' + file.name);
},
'onUploadProgress': function (file, bytesUploaded, bytesTotal, totalBytesUploaded, totalBytesTotal) {
$('#progress').html(totalBytesUploaded + ' bytes uploaded of ' + totalBytesTotal + ' bytes.');
},
'onUploadError': function (file, errorCode, errorMsg, errorString) {
alert('The file ' + file.name + ' could not be uploaded: ' + errorString + '.\nError Msg: ' + errorMsg);
}
// Put your options here
});
});
</script>


In the body

<div id="progress"></div>
<div>
<asp:FileUpload ID="FileUpload1" runat="server" name="Filedata"/>
</div>


uploadify.ashx:


using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.IO;
using WebApplication.Sources.Log;

namespace WebApplication.uploadify
{
/// <summary>
/// Description résumée de uploader
/// </summary>
public class updloadify : IHttpHandler
{
private static readonly String className = "updloadify";
private static readonly Logger log = LoggerManager.GetLogger(typeof(updloadify), className);

public void ProcessRequest(HttpContext context)
{
context.Response.Write("1");
}

public bool IsReusable
{
get
{
return false;
}
}
}
}


check-exists.ashx:


using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

namespace WebApplication.uploadify
{
/// <summary>
/// Description résumée de check_exists
/// </summary>
public class check_exists : IHttpHandler
{

public void ProcessRequest(HttpContext context)
{
context.Response.ContentType = "text/plain";
context.Response.Write("0");
}

public bool IsReusable
{
get
{
return false;
}
}
}
}


In the Web.config, I've put:


<location path="uploadify/uploadify.ashx">
<system.web>
<authorization>
<allow users="*"/>
</authorization>
</system.web>
</location>


Here is what I've observed:

The function ProcessRequest, from check-exists.ashx is hit when I put a breakpoint.
The function ProcessRequest ,from uploadify.ashx, is not hit when I put a breakpoint.

Then, I decided to upload a very small picture of 44 661 bytes. The function called by the onUploadProgress event displayed 45175 bytes uploaded of 44661 bytes.

Wtf???

Where did it find 514 bytes?

Yeah, okay, maybe the file is corrupted. So, I created a simple txt file with only character 't' inside and I tried to upload it.

Here is the result: 415 bytes uploaded of 1 bytes.

PS: I know that the check-exists.ashx and the uploadify.ashx scripts are not good and that it's normal if my file is not uploaded. But actually, I don't care about that. I just try to hit the breakpoint which is in uploadify.ashx.

Can somebody tell me what I did wrong?

Thanks
