I'm not sure there's a property for you to use. This means you'll probably need to grab the AJAX toolkit and edit the JavaScript for the calendar control yourself.

Hi,
I want to open only one PDF file using singleton pattern.I have written a code as follows on button click event:-
FileInfo objFile;
string strFileName;
strFileName = "User Manual - Quality Feedback System.pdf";
objFile = new FileInfo(Server.MapPath(ConfigurationSettings.AppSettings["App_Name"]) + "\\" + strFileName);
Response.Clear();
Response.ContentType = "application/octet-stream";
Response.AppendHeader("Content-Disposition", "attachment; filename=" + objFile.Name);
Response.Flush();
Response.WriteFile(objFile.FullName);
Response.End();
The problem with the above code is that it opens more than one PDF file if button is clicked more than once.How can I make sure that one PDF file gets opened using Singleton design pattern.I am clear with the concept of singleton pattern but I am not able to implement this concept in my problem.Please help.

are you loading the pdf file where the button exists?

Disable the button so that it can't be clicked again?

That seems unlikely given your post.

If you would apply the singleton pattern to this, it would mean that only one user could open the PDF file. Then you would have to restart the web application before another user could look at it...
I assume that what you really want to do, is to limit the usage per user, not per application. The problem is that the method that you use to open the file effectively prevents any attempt to check if the file is already open or not. The server code has no means at all of checking this, and you would have to open a window using client side code to have a chance to determine if there is already a window open or not. Even then, it depends on how the file is opened by the browser. If it's not opened in a browser window, but in a separate application (i.e. Adobe Reader), you can't determine if the file is still open or not. I'm not certain that it's ossible even if it's opened in a browser window.
So, what you want to do falls somewhere between "maybe working sometimes" and "impossible". Either way it's definitely not possible to implement the way that you suggest.
Despite everything, the person most likely to be fooling you next is yourself.

Ok, my purpose was to understand singleton pattern with some live example.Can anyone please explain this singleton pattern with suitable example.

Singleton Pattern is used when only one instance of a class is needed to provide services. In other words, only one instantiation. Here is an example:
public class SingletonClass
{
private static SingletonClass _myInstance;
//Private constructor so clients can not instantiate
private SingletonClass
{
}
// Clients call this when they need an instance of this class
// Needs to be static as it can be called without instantiation or instance of this class
public static SinletonClass getInstance()
{
if (_myInstance == null)
{
_myInstance = new SingletonClass();
}
return _myInstance;
}
}
The whole idea is the class checks whether an instance is available, if yes it returns it, else creates and returns it.
Let me know if you have questions.

you can set the relay property of SMTP server by following steps
open IIS
Right click on default SMTP server, then select properties
gott Access tab, there you will find Relay button, there you set the Relay restrictions.

Hi
I have just tried implementing a new control for RSS feeds for my website
The control worked fine locally but when I put it on the server it returned the above error message.
Anyone knows why this would be?
cheers

|

that means server unreachable from your server. Try to open the port to access particular host

So what your saying is that there is a port on the server which is blocking rss feeds from other websites
|
|
|
|
|
that could be one reason

The autoeventwireup , if it is set to false , it will not execute the code written in the page load function , and reverse is true.
My question is , how should i implement this case in the project and in which situation i should use it?
If you have an apple & I have an apple and we exchange our apples, then each of us will still have only one apple but if you have an idea & I have an idea and we exchange our ideas, then each of us will have two ideas!
