Can a Singleton pattern have a protected constructor? If so, why/how?
thanks.

The difference between private and protected, is that something that is protected can be access by an inheriting class.
So the reason why the constructor would be protected is that you could inherit the class and use the constructor.

I have 5 boys and they all love to play flash games online. When they fnish playing I look at the screen and there are about 900 pop-ups from them clicking on ads...$$$! 
I love da dotNet but I need to learn how to write these things. Does anyone have a recommendation as to where I should begin? I'm looking for a good book, online course, etc. I know absolutely nada about how these things are developed, but I intend to learn!
Any recommendations?

I believe you would have to get a version of Macromedia Flash and start from there. The Macromedia forums would give you a good start I imagine, but as for later development, I know that Barnes and Nobles bookstores as well as Borders bookstores carry Macromedia Flash development books. I haven't thoroughly looked through one of these books but it should be helpful as well. If you're going to go through Macromedia to get it's program, hope your wallet is full because it can get pricey, their new suite is $1000, or a smaller $165 through a university. If you have more questions, I have a friend who is quite talented in Flash and could give you some pointers if he's willing.

Hey all,
I need to force the broswer to raise a file download dialog box for specific files (http://support.microsoft.com/default.aspx/kb/260519[^]).
I have tried to search Google, and I found this link:
http://www.aspfaq.com/show.asp?id=2161[^]
Since I want to use this method (which works all the time - btw) in a dynamic way - where one page (download.asp) serves more then one file - I need query strings.
The problem is that is it unsafe to use when changing download.asp to accept query strings, because users can change the strings to download whatever files they want.
Any other ideas or alternatives will be appreciated.
Much Thanks.
Regards,
Zdr.

Verify that the path that comes in the querystring is in a folder where you allow downloads.
Or store the paths of the downloadable files in a database, and only send the id of the file in the querystring.

Or use session variables.
|
|
|
|
|
That, however, requires that you know what file is going to be downloaded when the previous page is created. If that page is used to select the file, you don't know what file the user will select.

|
Use linkbuttons or regular buttons and do the Session.Add in the Click event handler.
Obviously this won't work with regular old html anchors or asp hyperlink controls.
|
|
|
|
|
And then do a redirect? Causes another roundtrip to the browser, but it works.

Yeah, its certainly not the best way... but it might be the easiest.

I have a window service which is using a web service.
Now the window service is calling a web service function after a particular interval, so eash time a new web service object is created.
Is there a way i can use a single object but since it's a web service function the problem is if i use a single object then it will retain the previous request values which i dont want.
Can anyone help?
Thanx in advance

Well,
I think that you have to keep in mind that the HTTP is a stateless protocol. This means that once a request is served tha server has no idea of where the next request is coming from.
Hence, every request will instantiate a different object...
Out of curiosity, how many requests does your system perform?
Make sure you kill all objects and database connections.

i thinking to put an ip address tracker on my site to track my visitor so i know where they from. how can i create it?
|
|

There are many ways to due this. In ASP.NET you can use Request.UserHostAddress to get the IP, then just log it somewhere. But it sounds like what you really want is the referrer which is the website that the visitor came from. You don't need their IP to get the referrer. It will be in your IIS log. Or, you can use a free service from sitemeter.com , statcounter.com, google.com/analytics which is what I'd recommend for you. They will provide you with a small script to put on each page of your site. I use Google Analytics myself, which will provide you with a lot of valuable data, referrer being just one of them.

How do you create IE add to favourites functionality, in ASP.NET webforms. I have an old ASP application but the CODE is unmaintainable so i am porting over to ASP.NET C# and i want to simulate this fucntionality. I was wondering was there an old Microsoft control for this like IE webcontrols? Any help would be appreciated.

Hi, I posted this in wrong forum earlier, my apologies.
My issue is I have a web form, that is a radio button list, each a different name (obviously), with a button below. I am trying to use SelectedIndex, with code behind the button, so that when a person selects one of the radio buttons, they are directed to a particular webpage. I just can't seem to find the right code to use behind the button_Click event.
I have been trying to use HtmlLink but I don't think that's right. Is there a web browser class name or attribute that I can use to send someone to a new webpage? Below are some screenshots, if they help any:

I'm not sure I get what you want, but if you want to redirect a user from the codebehind, you can use Response.Redirect("url");
Hope that's what you're looking for.

I believe user and name are reserved words.
Try [user] and [name] instead and see if it helps, everthing else seems ok to me.

You must buy:
1- domain name
2- Hosting support with ASP.NET
when you have a server you can upload all webpages into your server.
and test your website:
Ex:
http://www.yourdomainname.com
