Connection time out + excel file upload + ajax async as a fix?


Thank you in advance for taking the time to read this.

I have a C# ASP.NET page that allows users to select 2 excel files from their machine and click a button to compare and look for differences.  Any difference is output to a gridview for them to review.  The code works brilliantly on my machine, on other machines inside our network, ect but when we try to access this page from outside the network and use excel file sizes around 1mb a piece, we're seeing a connection timed out error in IE (v6 and v7).

Due to limitations beyond my control, I can not save the files to the server first and then do my comparison code.  Instead I have to read the files to memory and am using a .dll found here, http://exceldatareader.codeplex.com/.  It basically reads the excel files into datasets, which are then passed on to my comparison method.

What appears to happen is that the comparison code takes some time, depending on the file size.  For example, 20kb Excel files net results with no errors in just a few seconds.  200kb files take longer but still succeed.  1mb files, though, get the connection timed out but only in IE and only outside our network.

So my thought was that perhaps the browser isn't getting the results back from the server fast enough and issues the connecti

Upload file control intefering with javacript and Sys.WebForms.PageRequestManager.getInstance?

Ok I'm trying to use the dreaded Upload File control and it's not within an UpdatePanel. Here's what I have, I'm using jQuery to display messages on the client side from the server. One of the things I'm doing is I'm setting up a script to run using: Sys.WebForms.PageRequestManager.getInstance().add_endRequest(iamloading); and in my iamloading I have: function imaloading() {    $(document).ready(function () {        displayMessage();    }) } Not to bore you with details but the displayMessage is where I am doing the jQuery, this has worked for ever.Now I'm building this page with the Uploadfile control and this stops working and if I remove the control it works again.I've made sure that the function handler is created for iamloading but it never fires as though something has unregistered the event. Any help or suggestion would be of great healp.Thanks

ASP:Upload control . Uploading into a SharePoint Document Library Subfolder and FILE NOT FOUND error

RE: ASP:Upload control . Uploading into a SharePoint Document Library Subfolder and FILE NOT FOUND error Two Issues, apparently unrelated. I have subfolders like this /ApplicantDocuments/20 and /ApplicantDocuments/21 (where 20 and 21 are my subfolders and ApplicantDocuments is my library. 1. The below function is erroring with file not found, but I confirmed I'm sending the fully qualify path (i.e c:\test.txt) to System.IO.FileStream content = System.IO.File.Open(documentFileName, System.IO.FileMode.Open); 2. Even if it worked, looking at the code, I'm not using argument foldername.  I'm passing 20 to the argument. How can I make sure it uploads into subfolder 20 of ApplicantDocuments? Thank you.     Just testing in test environment. Will tighten code once it works.   public void UploadDocumentToSite(string foldername, string documentFileName) {      SPSite siteCollection = new SPSite("https://xxxxxx");      SPWeb web = siteCollection.OpenWeb();      //SPSite.AllowUnsafeUpdates = true;      //Web.AllowUnsafeUpdates = true;      string Lib = "ApplicantDocuments";      SPFolder destFolder = web.GetFolder(Lib);      sendmail(documentFileName+" "+foldername);

Ajax file upload: example needed



So far, I have built a MVC application that has a file upload form. The upload is done the "old" way, i.e. with a full postback.
Now, I wish to do the upload in the background using AJAX. There are a lot of samples for asp.net, but no for MVC.

Could someone give me an example of an upload form using AJAX in a MVC application?
How can I change my application to work with AJAX?

Thanks a lot for your help.
