|render| |
I've started to add the time taken to render a page to the footer of our internal web applications. Currently it appears like this
> Rendered in 0.062 seconds
Occasionally I get rendered times like this
> Rendered in 0.000 seconds
Currently it's only meant to be a guide for users to judge whether a page is ... |
Rather than relying on your users to look at the page footer and to let you know if the value exceeds some patience threshold, it might be a better idea to log the page render times in a log file on the server. Once you have all that raw data, you can look for particular pages that tend to take longer than normal to re... |
Just simple things - move messages to appropriate folders, forward some stuff to an email2sms address, move spam to spam folder. One thing I'm kind of proud of is how to mark your spam as "read" (this is for Courier IMAP and Maildir, where "read" means "move to different folder and change the filename"):

"Rendered instantly" sounds way better than "Rendered in less than a second". |
Not sure whether I understood correctly your intentions but let's see if this one helps.

A good way to get started is to concentrate on the "Springframework". The Spring portfolio has grown to a big pile of projects around various aspects of Enterprise Software. Stick to the core at the beginning and try to grasp the concepts. [Download][1] the latest binaries and check out Spring's petclinic example once ... |
If you are accessing this from an API based client (I'm guessing that is the case because of the '?'s in the query) you can do this from your program rather than through SQL.
Note: The rest is for JDBC syntax, other APIs/languages will be different syntax, but should be conceptually the same.

I like to use rectangle for 2 main purposes, inserting the same text on every line, or killing a column of text (similar to Dave Webb's answer).

Is there a way to make WatiN click a link before the page finishes loading |
|unit-testing|automated-tests|watin| |
We're using WatiN for testing our UI, but one page (which is unfortunately not under our teams control) takes forever to finish loading. Is there a way to get WatiN to click a link on the page before the page finishes rendering completely? |
You can create a volatile registry entry. It will only exist untill the computer is restarted. This solution is very much "hackable", but it is simple and may suffice for what you want to do.
Take a look at the REG_OPTION_VOLATILE [here][1].

Linking combo box (JQuery preferrably) |

I am wondering if anyone has any experience using a JQuery plugin that converts a html

I guess you could probably use javascript to handle a selection event (my ja... |
Getting DIV id based on x & y position |
|javascript| |
The problem I'm trying to solve is "What's at this position?"
It's fairly trivial to get the x/y position (offset) of a DIV, but what about the reverse? How do I get the id of a DIV (or any element) given an x/y position?

Use a JQuery selector to filter the list of all DIVs for one that matches your position criteria? |

If you have control of the query that is returning the results, you can use ISNULL() to return non-null values like this:

If your situation can tolerate these magic values to substitute for NULL, taking this approach ... |
Create a mouse event listener, then trigger a mouse event at that location. This should give you the entire stack of elements at that location.

Why limit yourself to .NET 2.0. .NET 3.0 (or 3.5) contains WCF and is a solid, performant communications subsystem with good security. .NET 3.0 is just .NET 2.0 with additional libraries (WCF, WF, WPF). |
There are a couple of thinks to keep in mind if you are starting with OSGi.

For many types (integer, double, DateTime etc), there is a static Parse method. You can invoke it using reflection:

Spring is also very much about unit testing and therefore testability of your classes. That basically means thinking about modularization, separation of concerns, referencing a class through interfaces etc. |

You can use the IFilter interface built into Windows to extract text and properties (author, title, etc.) from any supported file type. It's a COM interface so you would have use the .NET interop facilities.
