Caputurig Back Button Event & Force The Page To Load From Server:

The ASP.Net BulletedList control can be configured as list of LinkButton controls using its DisplayMode property. You can declare the Click event of BulletedList control that will execute when a user will click any of the LinkButton item. The Click event of ASP.Net BulletedList control works only if the DisplayMode property value is specified as "LinkButton". When the user clicks on the LinkButton item of the bulletedlist control, it sends the ASP.Net web page to the PostBack and executes the server side code provided for its click event handler.

Sometimes we are in a situation that we don't want the user to visit the previous pages. This can be a scenario that users logs out but uses the back button to navigate to the pages. In this article I will tell you some simple ways you can use to prevent user from going back.

An approach to displaying a "please wait" message/animated gif following a button click using encapsulated client-side JavaScript.

It is often useful upon a form submission in a web application to display a "please wait" message, or animated .gif image, particularly if the submission process lasts a few seconds or more. I recently developed a survey submission application in which internal users upload excel spreadsheets through a web page. The application inserts the uploaded data from the spreadsheets into a database. The upload/insert process may only take a few seconds, but even a few seconds on the web is a noticeable wait. When testing, some users clicked the upload button repeatedly; it was useful to provide a visual clue that the upload was underway. For that matter, it was useful to hide the upload button altogether, preventing multiple clicks. The control presented here, a subclass of the Button control, demonstrates how client-side JavaScript code encapsulated in an ASP.NET server control can provide such functionality conveniently.

All of the sudden I'm getting the following error on my local web server (Win7 64bit, IIS 7.5).  I've uninstalled & reinstalled IIS locally and it didn't fix it.  IIS is set to start up automatically and I can see that the service has been successfully started.  Upon a fresh reboot if I go into IIS and click on start website I get the following error:

"The process cannot access the file because it is being used by another process.  (Exception from HRESULT:  0x80070020"

If I try to start debugging on my local website project I get the following error:

"Unable to start debugging on the web server.  The underlying connection was closed.  The connection was closed unexpectedly."

Any ideas on what I can try?  I've been doing research on the issue and Microsoft suggest making sure no other service is listening on the same ports.  I've verified that this isn't the issue.

Hi.

We had a website deployed on IIS server remotely say www.liveserver.com.

We recently decided to make a copy of the website internal to the organisation so we brought a server and copied all the code from live server and configured it and say it is http//archives-testserver.com

Everything seems to work fine but while navigating and clicking on certain module  links within  http//archives-testserver.com......the domain name is getting rewritten to www.liveserver.com and user is made to navigate on the live site. I wonder where this configuration is with in IIS...

I looked under properties under website identification and everything is referring it as http://arhives-testserver.com.  also thr is a file called securityRedirect.inc and ifor handling errors and all the references have been changed and couldn't find anything in web.config.

I would really appreciate if anyone can guide in right direction, where else to look for probable reference to live site?

I've got a Imagebutton in a repeater.
Code:

<asp:Repeater ID="repImages"  runat="server">
                    <ItemTemplate>                       
                        <div>
                            <div><asp:ImageButton ID="btnDeleteImage" Width="7" Height="7" runat="server" AlternateText="Verwijder afbeelding"  OnClientClick="return confirm('Weet u zeker dat u deze afbeelding wil verwijderen?');" OnClick="ImageButton_OnClick" ImageUrl="~/images/spacer.gif" /></div>
                            <img id="imgImage" runat="server" src='<%# GetOccasionPath(int.Parse(Eval("ID").ToString()),Eval("BaseFileName").ToString(), TypeImage.thumbnail) %>' />
                        </div>
                    </ItemTemplate>
                </asp:Repeater> 

 

It is displayed well, but if i press the button btnDeleteImage he doesn't even run ImageButton_OnClick , also there is no data included just for testing...
protected void ImageButton_OnClick(object source, EventArgs e)
    {
       
    }

 

But still i get this error:

Invalid postback or callback argument.  Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page.  For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them.  If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.

Also enableEventValidation="true" is placed in the page.
What can i do to solve this?

Hi

I need to know if a web application deployed in a 64-bit server runs as a WOW64 process or a 64-bit process if the web application's pages are compiled as PE 32/x86 ?

I mean I have read a lot about normal console applications or executables with PE 32/x86 run as WOW64 on 64-bit servers. But what about web applications( all i can compile is the pages which are dlls)? The only process I can think of is w3wp.exe for web apps. Please explain. I am confused.

Thanks in advance

Have a project where I need to access a RSS feed.   The issue is this RSS feed, you need to be logged in as a user.   They have a simple web form (login + password).   How do I?

1) Post a web form with my login and password

2) Maintaining Session (w/successful login), do an additiional GET to retrieve the RSS feed.

I am doing this in an ASP.Net page so it all happens server side in VB.Net

Brian 

I'm doing an application which has already contains a master page named Master.master. And all related web forms(Webpage) are running well. But I create another master page in same application named Profile.master for some other web form(Webpage). But this time some of the related pages are running a blank page and some are generating an error that is:-

is not allowed here because it does not extend class 'System.Web.UI.Page'.

please help me to rectify this error.
