Yes you can generate the Alert Message using Javascript.
But there is no need for alerting the message if teh user wnat to post the message please check he is logged in or not. that itself is ok.
Why are you trying to do the Application more complicated.

A simple doubt. An aspx page is reading contents from XML file. Will this make any problem if more than one users accessing the page at a time. I use XMLTextReader to read XML files.

You mean question?

As long as you open the file only for reading, there is no problem.

Hi,
I posted yesterday about this and did not find a solution. I am trying to create a custom control using the instructions given here:
http://blogs.msdn.com/coding4fun/archive/2007/05/05/2429765.aspx
If I use the local host for running the site, it works fine. But if I try doing the same on our web server, I get the following message, even if I don't insert the custom tag into the aspx page:
<br />
Compiler Error Message: CS0246: The type or namespace name 'myControls' could not be found (are you missing a using directive or an assembly reference?)
NOTE: This error is shown when the page loads, and not when it compiles. It compiles without errors.
I'm using Visual Web Developer, although I also bought Visual Studio 2005 Standard recently. I am connecting to a remote web server using FTP.
Does anybody have any suggestions? This is driving me crazy. Any help would really be appreciated.
Thanks,
James

We have the following requirement coming up from our client.
Framework 1.1,c#
Ours is a Content(Mainly O/S files) Providing System. Files(.pdf,etc) will be stored in folder(s). Google will be given links to these contents. For e.g.http://<webserver>/<virtualdirectory>/<folder>/<filename>.
We may need a login for seeing some of the contents. We have following three options.
1. An aspx page -> download.aspx?file=<filename>&otherparam=<paramvalue>
OtherParam will control whether login is required for downloading this content.
2. HTTPModule which will control all the requests coming to Virtual Directory
3. Forms Authentication which will invoke the login page automatically.
Suppose if we give a link as in option 1, will google be able to crawl the PDF and search for keywords. How google crawls any pdfs and searches for keywords? I searched google itself and could not get the exact idea.
Second and third option also works.
We will check for authentication(Authentication through third party web service.) in all the options. User also will be coming through URLs listed in google search. How to differentiate between google crawling and external user so that authentication may be turned off during runtime to increase performance during crawling.
Help would be greatly appreciated.

I think it can't.
K.P.Kannan wrote: How google crawls any pdfs and searches for keywords?
Google can't open the PDF and search for keywords.
K.P.Kannan wrote: How to differentiate between google crawling and external user so that authentication may be turned off during runtime to increase performance during crawling.
There is no efficient way to find out the request is given by a spider or normal user. And one more thing google won't be able to crawl efficiently a page that uses session id's and authentications.

Frankly you have to choose if your content is publically available or not. You can't make information available only to Google, as they will cache the pages and make them available to everyone.

Open a Crystal Report in Visual studio.
Press Ctrl + Alt + T,
You will get Field explorer window in left hand side.
There you will find Formula fields,
Right click select New...,
You will get a dialogue texbox to type a name for formula,
when you type the formula name you will get a formula window.
there you can write your formulae.

because For instance, if you define a custom error for the status code 404, ASP.NET will issue it anytime you refer to a non-existing .aspx page
The custom errors are only issued for those elements handled by ASP.NET. For instance, if you refer to a non-existing .htm page, IIS issues the standard 404 error

This is Because web.config is not having any role in serving HTML or PHP pages. Webserver will be doing this job. Web.Config will be working only with the extensions mapped with aspnet_isapi.dll.
You can redirect HTML or PHP file by changing the default 404 error message in IIS.

I think you are confuse in the loginUrl
loginUrl set to the page which is the URL to use for redirection if ASP.NET does not find an authentication with the request.
means this should be the page where you want to redirect the user if the authentication fails .
Thanks and Regards
