Problem uploading in FileVista control - connection closed

Hello,,

We just purchased the control and are attempting to put it in our application.  We have the upload working for tiny text files but asd soon as we try something a little larger (i.e. .docx, xlsx), the FileVistaControl_Failed event fires (after it times out) with a message:

"The connection has been closed between the browser and the server."

We're not sure what the issue is here.  We have a hard-coded path which works for the text files.  Here's the code: 

Dim fileVistaControl As FileVistaControl = DirectCast(LoadControl("~/FileVistaControl/filevista.ascx"), FileVistaControl)
fileVistaControl.Style = ConfigurationManager.AppSettings("fileVistaControlStyle").ToString ' "width: 800px; height: 600px"
fileVistaControl.Language = ConfigurationManager.AppSettings("fileVistaControlLanguage").ToString
fileVistaControl.LicenseKey = ConfigurationManager.AppSettings("fileVistaControlLicenseKey").ToString

Dim curriculum As New FileVistaRootFolder("Curriculum", "C:/VSProjects/CCCM/V1.0x/WebSite/Upload/Site0/curriculum/")
curriculum.Permissions = FileVistaPermissions.Full
fileVistaControl.RootFolders.Add(curriculum)

We commented out the quota and allowed file types to see if that was the issue.  Our environment is VS2008.  Any clue on this issue?

A bit more information - our error handler is returning the following:

System.Web.HttpException: An unhandled exception occured in the upload module.

Are you using Forms Authentication or another HTTP module or an Application_BeginRequest function (global.asax) in your project? These 3 things can effect the upload module of the control. The upload module should be the first one processing the request.

These topics may be helpful:
Upload with Forms Authentication
httpmodules limit the size of upload

Cem,

That was it - we had some code in Application_BeginRequest in globals.  As soon as we commented it out, it worked.

Thanks for the quick reply

If you need to run that code in Application_BeginRequest then you can add some checking code at the top of the function like this:

if( Request.RawUrl.ToLower().Contains( "filevistacontrol/upload.aspx" ) )
            return;

This way you can exclude the requests for control uploads and run your code for all the other request.
