Screenshots in DOS

Operating systems : MS-DOS 6.0+, FreeDOS 1.0+

There are several programs for taking screenshots in DOS. SNARF, for instance. Using this application succeeded in taking screenshots in most of the cases. Also, the screenshots' quality (.BMP files) by SNARF results to be the highest among the programs tested: ScreenThief, VideoThief, FLIP, GRABBER, SNARF.

Using SNARF with default settings is straightforward, but there is a shortcoming - SNARF always saves screenshots to the folder where the user is currently in. That could be inconvenient or unacceptable. And there is no obvious way to change it. But there is a roundabout option. The initial idea had been found on this page. The result based on it:

1. SNARF [ Download ]

2. Open SNARF.EXE in a text editor in text mode (not hex), find snarf000.bmp and replace it for s:scn000.bin

3. Create a batch file, S.BAT for example, where besides a string for starting SNARF.EXE will be a command assigning the path to the folder screenshots will be saved into to a virtual drive S: The folder and path may be any:



4. Start SNARF:

S [or S.BAT]

5. To take a screenshot:

Alt + S

There will be two beeps. The first at the beginning and the second one as a sign the process has completed successfully. After the screenshots are taken, go to the folder where they are saved in and replace the file extensions from .BIN to .BMP

SNARF - Freeware.

CSS rollover. Changing background image position


CSS rollover. Changing background image position. Example: CSS rollover. Changing background image position HTML / XHTML. Code: <div class="example"> <a href="css-rollover-changing-background-image-position.htm">CSS rollover. Changing background image position</a> </div> CSS. Code: .example {position: relative; top: 0px; left: 0px; height: auto; width: 100%; white-space: nowrap; padding: 10px 20px 10px 20px;} .example a {height: 35px; width: 100%; font-size: 24px; line-height: 35px; color: #006; text-decoration: none; text-align: right; display: block; background: url("bgimg.png") no-repeat left top;} .example a:hover {color: #c00; background: url("bgimg.png") no-repeat left bottom;} Background image: CSS rollover Changing background image position The concept : 1. A link with width and height declared explicitly (here it is 100% and 35px), plus display: block - this makes a 100% by 35px rectangle, the whole area of which is a hyperlink. Line-height is declared explicitly as well, equal to the rectangle's height (35px here) - it helps to have the same vertical alignment of the link text across various web browsers. Text-align: right is added to move the link text to the right in the the link block. (The link block area is highlighted in green to make it more obvious) CSS rollover. Changing background image position 2. An image for the link block area background with height equal to two heights of the link block area is created. The image has two parts, the upper one and the lower one, each of height equal to the height of the link block area; here it is 35px. 3. The background image URL is added to the background CSS property of the link. The CSS background property values of no-repeat and left position the background image to the left of the link block area. The CSS background property value of top places the upper part of the background image on the same level as the link text. 4. The background image URL is added to background CSS property of the link's :hover pseudo-class. The CSS background property values of no-repeat and left of the link's :hover pseudo-class position the background image to the left of the link block area. The CSS background property value of bottom of the link's :hover pseudo-class places the lower part of the background image on the same level as the link text, when a user moves the mouse pointer over the link block area. So, when there is no mouse pointer over the link block area, the upper part of the background image is placed on the same level as the link text. When there is a mouse pointer moved over the link block area, the lower part of the background image gets on the same level as the link text. Mouse out - the upper part is displayed, mouse over - the lower part shows up. And no need to preload any additional images. CSS rollover.

Internet Explorer 3


Features : Screenshots : Download links World Wide Web service with its online experience like hypertext links, surfing, web pages as a combination of text and images / multimedia brought Internet to general public. As to general public, it all very much revolves around the web browser. The first web browser ever, WorldWideWeb (later renamed Nexus) had many of the features later to be considered as standard for web browsers, but it was an experiment, accessible and known to very few. The rest of users might expect more likely only a text-mode interface experience through a text-based web browsers like Line Mode Browser. The turning point for the World Wide Web and all Internet was the advent of Mosaic, a graphical web browser, in 1993. First for Unix and then for Apple Macintosh and Microsoft Windows. Mosaic was not the first web browser for Windows though and it could not supersede Cello, the first and initially the only web browser for Windows. Microsoft Windows was the fastest growing major platform for PC in the first half of 1990s. But Microsoft did not seem to recognize the importance of the web browser then. So the main competition under Windows at that time was among several versions of Mosaic and Cello. This competition gave birth to Netscape web browser, which became the dominant software of its kind for several years. This success and great public attention attracted by World Wide Web by 1995 made Microsoft to join in the efforts. Internet Explorer 1 was just a first experiment. Internet Explorer 2 was intended to push the Internet Explorer case - it was made available to all Windows users for free, even commercial companies. But Netscape positions were not much undermined, Internet Explorer 2 being distinctly weaker in many features is among the reasons for that. Only after the release of Internet Explorer 3.0 Microsoft browsers began to close Netscape in qualities. Internet Explorer 3 was not the first Microsoft attempt to find technical and marketing model like were Internet Explorers of 1 and 2. And it was not the first Microsoft modern web browser, the first for Microsoft to beat and surpass Netscape and all other web browser competitors like Internet Explorer 4 was. But Internet Explorer 3 still was the first in some things: the first commercial browser with Cascading Style Sheets / CSS support, the first Microsoft web browser without Spyglass source code and the first Microsoft web browser to gain a significant user share, 20-39% by the end of 1997 [ 1 ]. Still, Internet Explorer 3 was a transitional, intermediate piece of software between the early browsers and the modern ones. As to its modern state, there is an interesting detail: Internet Explorer 3 can run under 32-bit Windows 7, unlike generally the 4.0-6.0 Explorers. Features HTML (with tables and frames) support is quite strong ( More ), Internet Explorer 3 lets some HTML tricks to be used without extra strain, like "HTML table borders without CSS". CSS support in Internet Explorer 3 is weak ( More 1 ) ( More 2 ). Internet Explorer 3 also supports VBScript, ActiveX (more than 1,000 Controls), Java applets, inline multimedia, VRML and a Microsoft's reverse-engineered version of JavaScript named JScript. All of the versions and capabilities corresponding to the level of the times. Internet Explorer 3 was released for several platforms: x86(16/32 bit), 68k, PPC, MIPS, Alpha AXP. And several operating systems: Windows 3.1, Windows 95, Windows NT, System 7 / Mac OS 7, Mac OS 8.
