In addition to “addClass, removeClass and hasClass without jQuery” article I wrote an example implementation of getElementsByClassName() method to catch a collection of objects, referencing them by their class name, when you can’t or don’t want to use jQuery and it’s superb class-selectors.
I’m continuing my plays with JavaScript and time functions (after this article). If you want to log-off user after some predefined time has passed, you can do this for example with below presented solution.
If you would like to present an information to your user on how much time did he or she spend on your webpage, then here is a particular example on how to do this the easiest way I found.

I found original version of this function at breakingpar.com. I have slightly changed function to fit my own purpose and purged original article of a really huge amount of completely unnecessary blah-blah, leaving actually Javascript code itself.
There are at least three solutions, how to map drive letter or directory to a local folder, available in Windows. All are discussed in this article along with some side problems and examples on how each solution can be used.

Class manipulation methods in jQuery are really handy, but when you need just them and nothing else out of jQuery, then using entire library seems like a little bit mistake. Using own versions of addClass, removeClass and hasClass sounds like a better idea and for this reason I have wrote following article, where you’ll find an example implementation of these methods.

The task in this post is quite simple. Obtain ID (keyField) of a record holding data for clicked CGridView row and one or more values from it’s columns. If you can/want use jQuery, this isn’t to hard job.
Regular expression was always a nightmare for me. Even though I understand how powerful these can be and I’m trying to use them in many places of my code, they’re still a huge mystery for me.
For this reason I have wrote a simple memo-article with a links to useful blogs, pages and tools for or about regular expressions.

It is quite easy for not showing something in the first row in CGridView. You need to use 'visible'=>'$row > 0' row expression. But, it becomes difficult, when we want to show something in every row except last one.

You may notice, that many MP3 players (both Windows programs — not tested on other OSs — as good as external hardwares) are making their file lists in some strange order. This may not be a big deal, when talking about music (though, when listening to a particular album, you may get yourself pissed-off as well), but became a really pain in the ass, if we’re talking about audiobooks.

If you’re an “old-school” MP3 user, and ID3 Tag version 1 data is all you need to get happy, you may find a shit stick to version 2 of ID3 Tag a little bit annoying. If it is so, then the big question is, how to quickly get rid of ID3v2 data for many files? Many programs are allowing to do a massive ID3 tags (both versions) change/edit, but there aren’t many of them that allows to delete particular tag version out of many files massively. And here comes my little trick.

When CD or DVD is ejected from drive, Total Commander “resets” contents of the pane to nearest available drive (usually C:). It is normal and obvious because contents of CD or DVD are no longer available. But, the same thing happens even if Total Commander is in background. This might be seen as an annoying feature, because each time you change CD or DVD in drive, you have to manually again select that drive in Total Commander. Fortunately, there is an easy solution for this.

Since I have been developing in Yii for my “entire life”, I’m bound to MVC model. And since it suits me very good, I don’t want to and don’t plan to change it. Even though, it is nearly always good to know, what are the alternatives — MVP and MVVP.
When you right-click Windows Explorer icon on the taskbar in Windows 7, you can see list of recent items (i.e. recently opened folders) with an option to pin some of them permanently. On some Windows 7 systems user may experience issues with recent items and pinned entries list not being displayed, missing or cleared without reason. New items cannot be added to these lists.

The CGridView class in Yii is a state of art solution, that gives you out-of-the-box full model browsing features including filtering, pagination and sorting. The picture would be perfect, if not for default look of grid view, which is a little bit “nasty”! :> It is understandable, as Yii author focused himself on delivering perfectly working framework, that does not necessary have to be pretty in the same time.
However, basing on famous flexibility of all components in Yii, with a help of few simple steps, you can completely change the look & feel of your grid view.
Suppose, you place your self somewhere in the middle of Yii 1.1 experience ladder. You’re no longer new to Yii 1.1, but you’re not an experienced Yii developer in the same time. In this case, I strongly encourage you to spare half an hour or so on reading articles in Yii Wiki, that are grouped in this table-of-contents article. These articles contains a lot of useful information, a must-know for all experienced Yii developers, that are mostly not know to those with middle experience
Bear in mind that when writing JavaScript / jQuery code for handling user changes made to dropdown boxes, you must program your website reaction not only to onChange but also to onKeyPress events. Why? There is a rare situation, where user selects value by clicking dropdown and then using keyboard’s cursor up or cursor down keys. onKeyPress event will be fired in this situation instead of onChange event. And desired effect won’t work, if you put it only to onChange event handler.

You can use CActiveRecord::populateRecord method in Yii to create new record basing on existing one. And, as this descriptions means, you must use it like that:
[code language=”php”]
$data = $this->getUser($id);
$model = new Users;
$model = $model->populateRecord($data, FALSE);
[/code]
instead of (last line):
[code language=”php”]
$model->populateRecord($data, FALSE);
[/code]
because populateRecord creates new model instead of modifying existing one!
A default file encoding for every file in Netbeans is defined at project level — see Project Properties dialog, Sources category. But there’s nothing similar (possible) for particular files without a project. If you’re using Netbeans just as an editor then all files opened from outside any project will be scrambled, because Netbeans is not using UTF-8 encoding by default on all files.

I personally adore Diablo I and Diablo II. Since first version of this game is already fifteen years old (published in 1996) it requires special steps to play it on Windows 7. The most popular solution is to use IPXWrapper. However, in my case it required some additional works.

The Synchronize directories tool in Total Commander is magnificent and I’m using it very often for all my backup-like and sync-like works. The only thing, that I was missing is an ability to ignore hidden system files or files stored in .svn or .git folders, i.e. hidden version control files. So, I wrote to Total Commander’s author and received immediate response, that this is possible.

Even prettiest wallpapers looks pretty ugly when stretched by Android to fit different device screen size. Either used algorithm is poor or I have too high expectations, but most of my Windows wallpapers look like a real crap, when copied to Android and used there as that system wallpaper. Some idea is to prepare own set of wallpapers, especially fit to your device screen size. For this purpose it is good to know, how to calculate it.

Well.. at least on my QNAP TS-210 it is in:
[code language=”shell”]
/mnt/ext/opt/apache/bin/
[/code]
You can validate this by executing:
[code language=”shell”]
/mnt/ext/opt/apache/bin/php –version
[/code]
Which should show version PHP installed on your QNAP box.
…are possible! All you need to do is to use mklink program:
[code language=”shell”]
mklink /d "D:\Photos" "\\SERVER\Photos\Family\Dad"
[/code]
