Web applications are systems that run in browsers that perform functions normally associated with other client-based programs. One of the most commonly used web applications is email; instead of downloading individual emails to a local machine, the data is shown through a website. Other examples of web applications are collaborative systems like a wiki or an online game.

I am writing an eBook for self-publication on Amazon. In it, I reference a somewhat scientific article to support my conclusions if a reader requires such information. I converted the link to a tiny URL, but am afraid that if the web page is ever taken down by the publisher, that the link and thus the info will be lost. With permission from the author/website manager, what is the best way for me to store the article forever? Should I copy and paste it in a Word document, reprint it to my blog with permission........I need help please. (It also has some lovely graphics....how would you handle them?)

Thanks in advance.

Hi Folks

Another one that's causing me no end of headache. I have moved a customer's web sites from one cPanel server to another and the move went fine. However, they are saying that their sites are not sending Emails, for example from the contact form, etc.

When the sites were on the old server, everything worked fine but I have absolutely no idea where to look or what to look for.

Server is a CentOS 6.5 server with WHM / cPanel installed.

Any help would be gratefully accepted. I really need to get back to them with some sort of resolution as soon as possible.

Cheers

What we want to achieve is: -

Press the print button in the app and the printout goes straight to a specific printer with no popup selection window appearing.  The printer that we want to print to is not necessarily the default printer.

Can anyone assist?

Dear experts,

I wish to know the difference between Mail(), IsSMTP(), and IsSendMail() function from a php library called PHPMailer.

When should I use what function and which will be a better choice if I use a online web hosting plan as in shared hosting instead of dedicated host. Thanks

I've encountered an issue which I called a function Send() but the program didn't send out an email.

If i use SMTPDebug, will it shows me the possible errors?

Hello,

I've been experiencing a very strange behavior on PROD environment.  

I was told to tighten up the security that after logout, user cannot use browser back button to view pages.  Following the reference link below, I make it works on DEV that when user logs out, it clears session and redirects to login page.  However on PROD environment, on Chrome, Network tab, I see LogoutPage.aspx, status canceled in a loop,  the ticker keeps firing... and I can't do anything but close the browser.

Hello,

I am currently setting up a new store using Magento 1.9. I would like to have two automatic timestamps available in the catalog.

First, I would like to know the date the product was added

Second, I would like the date saved whenever the product is saved/updated.

Third, I would like this visible when editing the product.

Any help with this would be greatly appreciated.

Hi all,

I've been using this for a login for my clients.

http://www.php-login.net |  >>> Advanced version.

However I need to restrict the domain registration to only their company names...

I have the following however have no idea where to implement the code to...

		$access_list = array('example1.com', 'example2.com');

		$domain = substr(strrchr($user_email, "@"), 1); //extract domain name from email

		if (in_array($domain, $access_list)){ 
		echo "You are good to go";
		}else{ 
		echo "stop them from signing up";
		}

Hi,

I have a web application in which there is a function to download the file. It behaves differently as per different browser say in in chrome file is downloaded directly,in IE it ask whether to open,save or cancel etc.
We can't change the behaviour as far as browsers are concerned. Can we?

Now if user opens the file in the browser say he is opening in IE,then can user edit the file for example xls/word? Is there any security concern?

Hello everyone,

I moved my website hosting to GoDaddy and everything seems to be working except I am unable to bring up the site on my Phone (tested using iphone 4S, iphone 5 and Blackberry Bold native browser and Opera).

I get the following error: Error There are too many redirections for this web address.  I get the option to try again but obviously it does not work.

I looked online and the error might be caused by a cookie issue, I deleted all my cookies and it made no difference.

GoDaddy Technical support are totally lost.

I thought it might of been a DNS issue, since GoDaddy automatically puts in a site for mobile.domain.com so I switched it to go to the '@' But it made no difference.

Any good suggestions out there?

Thank you!

Hi Folks

I'm desperately trying to figure out how to set up my IIS 7 Server so that the default is for each web site I create is automatically placed into its own Application Pool. I've read document after document but for some reason it's not sinking in.

Can someone explain it to me in words of one syllable so I can understand how to set it up? :)

Cheers

My question relates to using css @media screen queries. For example, I have a 10" tablet that shares the same default screen resolution as my large 22" desktop display monitor, That resolution is 1920 x 1080.  The webpage I've designed - which basically is just a video player laid on top of a background image - looks and functions great on my 22" desktop monitor, but not all that great on my 10" tablet. Well, technically I guess it looks okay, but the usability of the video player becomes a little more awkward on the tablet (touch instead of mouse). So . . . is there some way that I can still use the @media screen query (or some other media query) to load a different background image for the tablet? In other words, I'd like to write a style sheet that would style the page differently for these two devices, even though they share the same screen resolution. Is that possible? Is there a way, for instance, to specify diagonal screen size in addition to pixel resolution in a style sheet in order to make this happen? I've just recently been introduced to media queries, so . . . there may be a very simple way to accomplish this that I'm just not aware of. (??) Thanks!

I am currently designing a project that will be handling a large amount of data with multiple people accessing and modifying some of the records.  I am trying to decide on a concurrency model that I can use so that if multiple people hit a record at the same time that there is some mechanism in place where we don’t discard previous changes as each person updates the record.

Best practices or advise?

14yrs ago at another company I did the below every hour
•      At 10 minutes after the hour = My ERP system FTPed an updated comma delimited CSV file to a directory
•      At 20 minutes after the hour = My eCommerce software (i.e. like Magento) processed the file, updating inventory, making “Qty=0” items INACTIVE so they don’t display on the site

What 3rd party Magento add-on can do this on the FREE version ?

Hello,

I'm wanting to build a application and a small piece of it is a "points of interest" that a user can enter on a google map application. I wanted to use Google maps but according to the terms and conditions it seems to be limited on what I can do with it. More specifically it seems that I can't store and it's data like address or latitude or longitude information. Which would mean Google maps is really just a session based solution if I'm understanding correctly. I just want to be able to store the info so that I can populate the map again when they return. Any thoughts out there on this? Maybe I'm misunderstanding their terms and conditions.

Thanks for any feedback!

We have a public (hosted) website.

We are making an internal webserver and need some advice how to setup a public URL for it.

1) Something like www.MyCompany.com/schedules/

2) Or should we register a new name or just use one of our public IP addresses? (we have 3 unused)

3) or something else?

Anyone have any tips or advice to set this up exactly?

(Bonus points for code so that Google and other search engines will not index our new site).

Thank you,
HappyTech

Here is a curve ball perhaps.

My compliance department has seen somewhere or heard from some one that it would be a great idea if our process flow that we need as part of our ISO9001 Quality management is published on an intranet.

The idea is that every process is drawn as a flow chart with clickable links at each stage to open up a list of documents that belong to that process.

This would allow a user to see where they are at each stage of a project and what forms they have to complete as well as help and support guides for this.

The intranet is not part of the workflow itself so does not need to harbour any interactive or dynamic functionality but act as a document repository that is accessible from a browser.

So my question is what software would you suggest for deployment, considering we have at least one server we can dedicate for this and it is an Active Directory environment?

Many thanks
capt.
