VBScript rollover. Image swap

Windows : Internet Explorer 4.0+.

VBScript rollover, using image swap. Two examples: several ways of applying VBScript in a web page.

VBScript rollover

Example 1

VBScript rollover. Image swap

HTML / XHTML. Code:

<a href="#" onmouseover="onMouse_over()" onmouseout="onMouse_out()"><img src="out.gif" id="rollover" alt="" /></a>

VBScript. Code (<script> tag including):

<script type="text/vbscript">

Sub onMouse_over()

rollover.src='over.gif'

End Sub

Sub onMouse_out()

rollover.src='out.gif'

End Sub

</script>

Note: an external VBScript script file may also be used. The code itself is the same (without <script> tag pair, surely). The file is linked to page very much like a JavaScript file would be:

<script type="text/vbscript" src="vbscript.vbs"></script>

VBScript rollover

Example 2

VBScript rollover. Image swap

HTML / XHTML. Code:

<a href="#"><img src="out.gif" id="rollover2" alt="" /></a>

VBScript. Code (<script> tag including):

<script type="text/vbscript" event="OnMouseOver" for="rollover2">

rollover.src='over.gif'

</script>

<script type="text/vbscript" event="OnMouseOut" for="rollover2">

rollover.src='out.gif'

</script>

Windows console applications. Multimedia

 

MPlayer : FFmpeg Media players appeared long ago, but their heyday began with the mass spread of personal computers powerful enough to play video files. This coincided with the mass spread of operating systems and other software with graphical user interface. However, a program with a graphical user interface is dualistic in its nature: there is a code responsible for graphical user interface, for the appearance and there is a code - for performing the task the given application has been created for in the first place. Both code complexes consume system resources, their response time to user actions makes up certain amount of waiting time. And in cases or concepts when appearance is taken as less important - less important to the point of sparing or almost sparing to employ it - console applications, among others, appear. Moreover, the segmentation of the GUI and of the engine makes it easier to change the graphical user interface or perform complex automated operations. The scheme is implemented for media players for Windows as well. MPlayer, for instance, in its usual form is a console application, starting up quickly, having fast response to user actions, consuming system resources almost entirely for its immediate task. And on this basis if desired, one or another graphical interface may be added for creating, all in all, a new application. MPlayer - / home page / Console media player for Windows.

Centering content of a web page by means of JavaScript and CSS. A block containing the content of a page is JavaScript + CSS centered horizontally and vertically. Two cases: 1. A block is centered, if screen resolution is equal to or greater than 1024x768 - [ Open demo page ] 2. A block is centered, if screen resolution is equal to or greater than 1024x768 + mouse cursor is moved over a link in an element of the page content - [ Open demo page ] JavaScript and CSS horizontal and vertical centering. The first case. Step by step. 1. A web page, the part of which is going to be the element the JavaScript + CSS horizontal and vertical centering is to be applied to: HTML / XHTML. Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <title>JavaScript + CSS horizontal and vertical centering.

Code: html {height: 100%; margin: 0px;} body {background-color: #fff; margin: 0px; height: 100%;} 2. A block element A (grey color) with dimensions declared explicitly, for instance 800 by 500 pixels and with relative positioning is created in the document's body. [ Open demo page ] HTML / XHTML. Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <title>JavaScript + CSS horizontal and vertical centering.
