Thanks for the tip, I never thought of that. Does the Application_BeginRequest event fire on every post back?

I think so but the way I usually do it is to wire up an event to page PreInit in Application_PreRequestHandlerExecute. It might not be the best way to do it (so I'm open to suggestions) but it works a treat.

I wanted to avoid using session vars, but I guess that is my only option at the moment. Thanks!

Just one more tip for you.

Create a static class to hold all your session objects. For example

public static class SessionItems
 {
     public static YourObjectType YourObject
     {
         get
         {
             Object result = HttpContext.Current.Session["YourObject"];
             if (result == null)
                 return null;
             else
                 return (YourObjectType)result;
         }
         set { HttpContext.Current.Session["YourObject"] = value; }
     }
  }

It makes it easier to manager your session objects this way, plus it prevents bugs from trying to access a session object that does not exist. Also prevents bugs that can occur from mispellings

Dear All,

I have a requirement that i want to send mail to all my user registered on my site in last 24 hours.

Manually its working fine but i dont want that a operator has to sit and search data then click on some button to send the mail. I want that by using some automated process that server automattically send the mail at the desire time.

Plz do reply what could be the possible conditions.

Thanks and Regards

Create an application that reads your database of registered users, selecting those users that have registered on the current day and generate your email. Sounds pretty straight forward, right ?

Are you familiar with a programming language such as VB.net or C#.net ?

Are you capturing the registered user with a date stamp of when they registered ?

Once the application is written, you could simply schedule it to run each night at 23:59 (just before midnight) to generate the emails.

My initial vision was to develop a "console application" which would be scheduled to run at a particular time. A console application is a Windows application that has no GUI, it looks like an old DOS program, just a black and white DOS box. The reason for this is that it is fairly easy to develop and test. Once this applcation is written, you could schedule it to run on your web server nightly.

I'm not sure how you would create a Web Application that would send these emails without some type of user intervention. You could create a simple web page that selects all of the newly registered users and when the operator clicks on a button the emails are generated and sent. I don't see how this could be scheduled to run automatically.

I am by no means an expert in web development. Smile | :)

How to check for duplicates before uploading.

I presume you are implementing website using asp.net/c# on the Microsoft platform:
First assure the IIS your website resided in have installed SMTP Virtual Server and some necessary configuration is well done.
Second when a new user registers into your website successfully, you can trigger a mailing event.

Hi!
I have a small upload site that I have built but one thing I can't work out is how to check to see if the file path has already been used.

When I upload just now I create a website address which is saved in doc_url within my table. What I want to check is that when uploading a new file, there isnt already an identical url created within doc_url.
If there is already a file within the database with the same path then I want to throw up an error message so the user knows there is already a file saved at this location with the same name.

I'm using VS2005, C#, ASP.net

Thanks for your help in advance.

But that means there are two files the exact same within the database, what I want is to have only 1 version of the url which means, one version of the file I have uploaded.

To explain a bit more, when I upload a file e.g. example.gif to a folder I automatically create a url e.g. http://localhost/folder1/example.gif

Now, if I upload a file with the exact same name to the exact same folder I want a message to be displayed saying, there is already a file with this name in this folder.

Just loop through that folder and compare the file names with your new filename. upload only when result is "no match found".

Very simple! You can handle that as below:

string filePath = Server.MapPath("~/folder1/example.gif");
if (File.Exists(filePath))
{
//show a message to the user
}
