Continuing problem - "Access is denied" client error

I have struggled with this problem for a couple of months now with no solution yet.

I am migrating an existing web site to a newer user-friendly web using AJAX and the AJAX Toolkit controls. I am using a couple of the tab controls on a couple of pages, including the default page. I am using VB 2005 along with SQL Server 2005. The production server is running IIS 5.1 (and yes, I have installed AJAX and the toolkit on it and yes, the dll files are in the bin directory).

Everything works fine on the development machine, but after copying the files to the production server and then viewing the site in IE (6 or 7) on any machine, there are "Access is Denied" errors when trying to use one of the tab controls.

I have searched the internet and did come across and article about this error, but it pertains to using IFRAME and I am not using any. I have uninstalled and reinstalled IIS on the production server, I have uninstalled and reinstalled both AJAX and the toolkit.

I am at a loss - is there anything that I am overlooking? I would like to have this newer website up and running by June 1, however if there is still these errors, I will have to revert back to the older non-AJAX enabled site.

Thanks for any information.

Anybody?

Here is a thought too and I don't know if this has anything to do with it, but my site is run locally at home using a static IP address. The URL is registered through Yahoo Small Business.

Would that have anything to do with it for any reason?

And to add to it, the error points tohttp://<the ip address>/thewebpage

Complex Type Serialization problem client -> server

I built a real simple sample that downloads an object to the client, then sends the object back up to the server. I love how easy this is, but there's a problem with the upload:
Here's what comes down:
{"__serverType":"Westwind.AtlasTest.busCustomer","Name":"Rick","Company":"West Wind","Entered":new Date(2005,8,25,1,10,16)}
and here's what goes back up:
{"Customer":{"__serverType":"Westwind.AtlasTest.busCustomer","Name":"Rick","Company":"West Wind","Entered":{}}}
Notice the Entered date is no longer set isn't serialized properly - it's empty and on the server side a failure occurs.
This brings up another question: What hapens on an exception? Right now a 500 error and an HTML error page goes back. There's no trigger and no error nothing that happens on the client side page?
+++ Rick --More info...
The failure above doesn't seem to be related to the date field even - it looks like complex types do not marshall up at all. Even doing this on the client:

function btnSaveCustomer_Click()

{

var Customer =new Westwind.AtlasTest.busCustomer();

Customer.Name = document.getElementById("txtName").value;

Customer.Company ="West";

// Customer.Entered =new Date(2005,8,26,20,54,56);

alert(Customer.Entered);

Service = Westwind.AtlasTest.SimpleService.SaveCustomer(Customer,btnSaveCustomer_Click_Complete,btnSaveCustomer_Click_Complete);

returnfalse;

}

Fails. What goes up to the server looks right (I assume) and it's apparently picking up the type properly:

{"Customer":{"__serverType":"Westwind.AtlasTest.busCustomer","Name":"Rick","Company":"West"}}
Here's what I get back:

Hi Rick,
I investigated this, and it is indeed a bug in the Atlas serialization code. In order for it to work correctly in its current form, you need to make sure that the fields you set into your client object (in your case Name and Company) have a matching publicproperty on the server object. Fields are not supported at this time, and maybe that's what you are using. If so, just switch to a property and you should be on your way. Thanks for reporting this issue, as it's definitely something we wnat to have fixed.
As for the fact that error reporting is lacking, it is one of those things that we didn't get to implement yet, but will be included in the next release.
Hope this helps,
David

Compare the page size of a control with AJAX call to without it

Hi,

I would like to capture the difference of a page' size (resulted from HTML markup sent to client) between a control with AJAX and without it, that is postback.

Could any give me suggestions about how to implement this function or tools can help me doing that.

Any suggestion would be appreciated.

Ricky.

If you're interested in just viewing the size differences, you could try using a utility like Fiddler, which will report back to you the size of the HTTP responses. Fiddler provides a lot of additional info that is useful to web developers - I'd highly recommend it.

Fiddler(v2)

u could try this...

with page on browser, save on your hard disk the source html (view/html from IE)

then do the same with the control without AJAX.

or viceversa.

the sizes of two files give you the idea.

:)

gmastro:

with page on browser, save on your hard disk the source html (view/html from IE)

then do the same with the control without AJAX.

This won't give you a true idea of the difference in sizes. When you use AJAX, you'll load scripts from external files using ScriptResource.axd and WebResource.axd. Those scripts will load, but in the source html, you will just see:

<script src="/Project/WebResource.axd?d=JIj7eF1JuZPjL4hPGAVvsg2&t=633059383787628338" type="text/javascript"></script>

And you'll miss the true impact, size-wise, of using AJAX.

Use Fiddler to compare page sizes for yourself... I would suggest reading this article first...

Hi, guys.

Thanks for yours enthusiastic replies.

Ricky.
