There is no easy fix. Here are two ideas:
1. Most web hosts are UNIX based, and a lot of them offer a CRON service for periodic actions. You could create a PHP page there that accesses your ASPX page, then tell their CRON to activate your PHP page periodically.
2. You might be able to do this: have your aspx page send a delayed mail to your web host (most have some facility to not immediately send a mail, but wait either some period, or some specific time, or whatever is considered the night shift). Then set up your mail account to filter for that specific mail and get it processed by the original aspx page.
Warning: this basically means the page is keeping itself active, which can go wrong in two ways: if the delay becomes too small or zero, you get a busy loop, and the web host will eventually kick you out; and when the loop breaks for some reason, it will not restart automatically.

I have incoming messages to specific email address. I want to loop through all the messages in that account then INSERT the email subject to the article_title and the body to article_url
How can I do that please

i would imagine, depending on how you get your emails, that a simple foreach should do the trick. what format are your emails?

Hi,
welcome to CodeProject.
Your question is very hard to read, with a lot of unformatted code. We recommend you use PRE tags (or the "code block" widget) to get code formatted properly, with indentation, and syntax coloring. You could still edit and improve your existing message! It is also good practice to be as specific as possible about compilation or run-time problems; e.g. an Exception tends to include a line number, telling us which line bombs is a big step forward.
I haven't looked at all the code, I want to signal GDI+ or .NET uses some strange exceptions when things go wrong. As an example (possibly spot on), Image.FromFile gives an OutOfMemoryException when the data in the file isn't using an image format the method understands.
So I suggest you:
1. look at the exact filepath you are using
2. consider whether you want a file on the client side or the server side
3. try and open said file, e.g. by double-clicking it in Windows Explorer; if explorer fails, so will FromFile.

If you go to google and search for microsoft you will see microsoft corporation the result and below that you will see some featured links from microsoft such as windows, support, etc and then you can see (more from microsoft.com)
What does this google technology called and how can I do it for my website?

That technology is called Crawling.Google searches for any content on all the pages available on Web.It even looks the tags, even seraches the entire pages for the searched keywords.
How many times a page is searched it makes your page get ranked higher and displayed in searched results on first few results. There are also many factors associated to it.
For details, Have a look
You dont need to do anything specific. Upload your site on web. Have really good contents that people are looking for. Also check above link for details.

When you create a web site on a new domain name, it will not automatically show up in Google results. Google is NOT reading the entire internet, it is not fetching random URLs. "All" it does is crawl from one page to the next, starting at some root point, and following (almost) all links it encounters. So putting up a new site as an island isn't going to work.
AFAIK in order for your web site to appear in Google results at all, you need to do at least one of these:
1. get your web site linked to on one or more pages that are already known to Google; communities such as Facebook, LinkedIn, CodeProject, ... may be a good starting point; a friend's site may be too.
2. report your home page to Google, see http://www.google.com/addurl/[^]; not sure if that really works though.
3. pay Google for a sponsored link; does not make sense to me, unless you're a big corporation.
And whatever you try, it takes a couple of weeks to get initial results!
Once your site is showing up in Google results, there are techniques to improve your ranking.

Hi there,
I'm writing a web service that's supposed to monitor client out there, using web clients.
I'd like to allow a user to read a status report using a web browser.
The naive solution i had thought of was having an <index.html> file, and updating it when needed.
The problem is, updates may need to be made very often.
Another problem may be that the web service might not have privileges to change the file, since it will be held by the iis, while serving it to the user.
Any good ideas or tips?
Thanks in advance,
Summer Bulb

A webservice does not have a file to change. It should provide access to services, such as, setting or retrieving data. I'm not very clear on what you are attempting to do or what you want to accomplish.

The idea is as follows:
Multiple clients will be pinging the web service to indicate activity.
The web service will store the ping information.
I would like to be able to display that information to a user useing his web browser (with a html file or something like that).
Am i clear now?

Ok, create an aspx page that reads the data and displays it, you know, basic ASP.NET. 
If you are thinking you can use the web service to display the page then you don't understand what a webservice is or how to use it.

Assuming your web service consists of one or more asmx files, all it would take IMO is one or more aspx pages that present the required information. Mind you, I haven't tried this, however I don't expect there to be any problem. You could use a database (or a static class) to hold the shared information.

Hi,

How i can set the focus on the row that i selected (after i pressed on "Edit").
Can someone please help me?

I've set it at Page_Init and it works great

you can just set this on the aspx page at the top in the declaration this might be a little easier.

Perhaps the snippet was not posted or formatted correctly but you appear to have the both the progress control and the button inside the update panel

|

Yes true
Why? Is it wrong?
So how can I do it?
|
|
|
|
|
The progress control should not be inside the update panel. See the example here[^] and while your at it read the rest of the documentation about UpdatePanels and how to use them.
Move the button outside the update panel and use a Trigger. Once again, reading the documentation will help.

I noted your comments and changed my code accordingly but the button is not not allowing disable

And how can I show it back from the code if my try...returned error?
