My web-app using .NET 3.5 and AJAX 3.5, is working well using the local
machine.
When running on the webserver (windows 2003 + .NET 3.5 installed) the page
works just fine, until I hit 'Next' wich is supposed to do a postback (in
the updatepanel) and show the next UserControl (it is sort of a wizzard like
app). Then I get 'Error on page.' in the bottom-left corner of IE and this
message :
Sys.WebForms.Pa geRequestManage rServerErrorExc eption: Object reference not
set to an instance of an object. (Line 605, char 13)
I tested this using Vista + IE7 and XP Pro + IE7.
I did not write any kind of javascript in these pages/usercontrols and am
really surprised about this.
If I turn off PartialRenderin g I get the following error during the loading
of the page :
'Sys.WebForms.P ageRequestManag er' is null or not an object (Line 925, char
5)
I really don't know what to make of this, I thought Ms-AJAX was just
supposed to be drag-n-drop AJAX.
Can anyone help me out, I'm moving toward my deadline really fast...
TIA,
Jurjen.

Turns out that somehow an outdated ascx was put on the site, this threw an
error on AsyncPostback After renewing the ASCX the problem dissapeared.

Hey,
I have a master.page and a Default.aspx page. I'm trying to use AJAX
to postback to the server. However, when I place the
<asp:ScriptManager ...tag on the Default.aspx page I get an "Element
'ScriptManager' is not a known element. This can occur if there is a
compilation error on the Web site."
What is the problem here? Am I missing something?

I have a server with about 50 web applications on it. I would like to
enable ASP.NET Ajax on all of them, but I don't want to spend the time
manually modifying each and every web.config. Can I simply add the
ajax entries to the machine.config instead? And, if so, exactly what
are the entries I will need to add? Thanks for your help!

Hi all,
I am using the ASP.NET AJAX Toolkit form http://asp.net/ajax
It has something called ModalPopupExtender to create a popup. You can view the live demo at http://asp.net/AJAX/Control-Toolkit/Live/ModalPopup/ModalPopup.aspx
This extender takes the ID of a control as the value of the "TargetControlID" attribute.
<ajaxToolkit:ModalPopupExtender ID="MPE" runat="server"
TargetControlID="LinkButton1"

I've stumped myself writing an app that uses Prototype and a bit of PHP. Here is what I have:

In AjaxPro, if you leave out the Callback parameter, it becomes a
synchronous call. Is it possible to perform a synchronous call with
ASP.NET AJAX?
Please limit responses to the question posed...let's leave the
discussions of why not async, or what does the "A" mean for another
thread.
Thanks for any help and examples of how to do it.

I built a development version of a live website on my hosted account.
However the development version is having problems with finding

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
