I have worked on some small web development projects where the server side languages have been PHP, Java and Lisp. Now I want to learn web development seriously. I don't want to use platforms based on PHP or Java. I also want to learn Python in general. Ease of implementation and learning value is more important to me than real-world imp...

I am designing a web app that has some information that needs to be transferred to a client side (non-browser) application (i.e. Outlook). Assuming the client side app has an API of some sort, I need for the web app to trigger the client side (based on a user clicking a link) to get the information and transfer it into the client app th...
I am trying to find a record in the database that has the lowest value of its datetime column. In simpler words, I want to find a record with the earliest time. I can use minimum to find the lowest value, but that will only return the value itself, and not the whole record. I suppose I could create another query, but I'm wondering if t...

Hi, I'm wondering if it's possible to capture details from the web page that a user previously visited, if my page was not linked from it? What I am trying to achieve is to allow users to my site to find a page they like while browsing the web, and then navigate to a page on my site via a bookmark, which will add the URL (and possibly ...
I need to device a way to learn if the user who surfs to my site has dotnet framework installed on his computer, and which version (less important). I need this to work at least with Firefox and IE 7 and up. Any ideas? (Is there any web service the Framework on the "localhost" exposes?) ...
When I hit the submit image I get some extra parameters in the GET request: main.php?selected=user_manager_main&mode=set_active&set_this_id=13&x=4&y=7 Please note the x and y at the end. I certainly did not define the x and y at the end. The values seem to be random. Here is the form code: echo '<form action ="main.php" method="get">...
The Same Origin Policy Documentation says this: There is one exception to the same origin rule. A script can set the value of document.domain to a suffix of the current domain. If it does so, the shorter domain is used for subsequent origin checks. For example, assume a script in the document at http://store.company.com...

One thing that I never can settle on is the structure of my backing beans. Furthermore, I have never found a good article on the subject (correct me if I'm wrong). What properties belong on which backing beans?...

Since I took the basic undergrad course in databases design and SQL I haven't really touched anything like this. So my question is - how would the database schema for a site like this one would usually look like? What are you generally expected to find? For instance, how are questions and answers stored? Are there some tools which allow ...
Hi, I have a rather pesky problem when trying to add a confirm popup message to the onclick event of a button. The problem occurs when trying to break the message onto a new line so the test wraps within the pop up window. If the \n is taken out of the string the code works fine. string confirmationMessage = "text text text text text...
I'm working on a PHP project with several developers, each who has their own style. The styles differ significantly, and can make the code really hard to read, and everyone is in agreement that we need to standardize our style. The issue I'm having is that I can't find any good program or system to help enforce standards for PHP. I've...
We're preparing to rewrite/restructure our corporate website and are looking for a CMS to back it. I need the CMS to provide a way of giving certain users in our company control over certain sections of the web site (i.e., allow our Marketing department to update press releases, our HR department to update job postings, etc). It should a...
Any good sources(links) about optimizing Telerik Web controls? I imagine that there are features that are turned on by default. These features require resources (javascript, css, images) to be downloaded on request. It would be nice to know what these feature are and to turn them off if not used. Do you know of such features? I'm prima...

Seeing as these are only day classes, I am by no means a pro at any of them but ...
