Webpage Update in Internet Explorer

Would you like to know when a specific Webpage was last updated ? After all, you do not want to think you are reading current information if the material was last updated in 1997. If you use Microsoft Internet Explorer, you can easily determine when a page was updated last. Navigate to the page you want to check and type into the Address Bar java-scriptalert(document. last Modified) and press Enter. A dialog box will open, display the date and time of the last update.
Note that you must enter the line exaclty as shown here. You can copy the line from here and paste it into the Address Bar if you like.

How Monitors can get an IT Manager promoted

While monitors may not be the most glamorous technology,they are a critical desktop peripheral and certainly represent a large percentage of any IT Budget.Monitors Direct's corporate account team specializes in money saving logistics and high quality monitors.

VIRUS,WORMS & TROJAN HORSES

Often email viruses,worms & Trojan Horses come attatched to blank mail.That is email with no body next.You can gaurd against some of the malicious attatchments by simply never opening mail with no body text.
If you get an email with an attatchment and nobody text,it's good idea to delete the message immediately.

If you use Outlook Express 5 or 6(not sure about ealier versions), you can automatically move all blank messages to a special folder.
Run Outlook Express and choose File/Folder/New.When the Create Folder dialog box opens, click "Local Folders" to select it and then click in the "Folder name" entry box and enter Virus. Click OK to your new folder and close the dialog box. Choose Tools/Message Rules/Mail . When the dialog box opens,click the Mail Rules tab (if necessary) and then click New. Now, select the check box labeled "Where the message body contains specific words".
Next, select the "Move it to the specified folder" check box.Under "3. Rule description" click "contains specific words". Now, type in a and press Enter, then type e and press Enter. Repeat this procedure for i,o,u. This adds all the English vowels to the list.
Next, under "Apply rule if ", select the radio button labeled "Message does not contain the words below". Click OK to continue. Under "3. Rule Description" click "Specified" and then double-click the new Virus folder. Click OK to close the dialog box. Back in Message Rules,click OK to save your selections and close the dialog box.
Outlook Express will now move any message with nobody text to the Virus Folder.

Some Websites are notorious for pop-ups. If you don't mind pop-ups, great. But if pop-ups really annoy you,you need to find a way to turn them off automatically.We know of two freeware pop-up Killers that do an excellent job. One is POW! from Analog X, and the other is Pop Up Killer from xFx Jumpstart.
Both these applications sit in the system tray,monitoring your browsing and closing pop-ups as soon as they open.

As you know,Netspace 6.1 is out now. But it doesn't mean that there is no longer any support for Netspace 4.x . You can still download bug fixes and security enhancements for 4.x .
To keep your Netspace 4.x browser current,choose Help/SoftWare Updates to navigate to Netscape's Smart Update Service.

Tips related with computer

1. When we on the windows in computer,one temporary file in Temp directory is created.Like this,when the computer is on every time, Temp file is created.

If Windows is put off without clicking on the shut down button, then the size of the Temp file is extended and the file like tgis(Temp File) is saved. and like this, many files are saved in Temp directory.And the hard disk is destroyed by this and the working capacity of the hard disk also becomes less. So by going into the Temp sub-directory,we should delete all the Temp files by time to time.

2. In Windows 95 & 98,when we put the CD in its drive,then it runs automatically(auto-run). then the program which we were doing goes in the background and the CD programs come in front. So the method to avoid this is that when we put the CD in its drive then we should press the SHIFT key on the keyboard. Auto-run will not be done by the CD-ROM drive.

3. In Windows 95,if there is the OSR 2 version in your computer and if u press the function key F8 and you get "Previous version of MS-DOS" in its menu and if you select that,the computer is hanged and if you reset the computer then it wouldn't get boot up again. After that you would have to insert the bootable floppy of Windows and transfer the system. Therefore, don't select this command in OSR2 Windows.

To recognise this(OSR2) type of version in your computer, click the right mutton on the icon of
"My Computer" and see its properties. You will see its version no. 4.00.950 . If you will see its version 4.00.950 B, that means your Windows is OSR2 .

4. In Windows 95 & 98, every program is opened by "short key". In this case the mouse is not used many times for double clicking on the program.

If you want to create a 'short key' then you should click the right mouse button on that particular program and Propertise will come on the screen and in that, 'short cut menu' will be there.So select it. In 'short cut key',press the key which you want (Key define). Then press'OK'.
In 'short cut',don't take the key which interfer your work or which makes you work.

5. In Windows 95 & 98, there comes "Registary Error" many times. In this case we have to format the hard disk and reload the programs. In order to resume,we have to go in run menu and select "reg edit".Then go in Registry option in which we have to select Export Registry file option and save the registry by any name. If you get any problem,then go in safe mode and boot the computer and select the Import registry file option and find the file which you have made in this option and select that file and import it and restart the computer.

5. ADVANTAGES OF USING FLOWCHARTS

The benefits of flowcharts are as follows:

1. Communication: Flowcharts are better way of communicating the logic of a system to all concerned.
2. Effective analysis: With the help of flowchart, problem can be analysed in more effective way.
3. Proper documentation: Program flowcharts serve as a good program documentation, which is needed for various purposes.
4. Efficient Coding: The flowcharts act as a guide or blueprint during the systems analysis and program development phase.
5. Proper Debugging: The flowchart helps in debugging process.
6. Efficient Program Maintenance: The maintenance of operating program becomes easy with the help of flowchart. It helps the programmer to put efforts more efficiently on that part.

6. LIMITATIONS OF USING FLOWCHARTS

1. Complex logic: Sometimes, the program logic is quite complicated. In that case, flowchart becomes complex and clumsy.
2. Alterations and Modifications: If alterations are required the flowchart may require re-drawing completely.
3. Reproduction: As the flowchart symbols cannot be typed, reproduction of flowchart becomes a problem.
4. The essentials of what is done can easily be lost in the technical details of how it is done.

Flow Charts (contd...)

The following are some guidelines in flowcharting:

1. In drawing a proper flowchart, all necessary requirements should be listed out in logical order.
2. The flowchart should be clear, neat and easy to follow. There should not be any room for ambiguity in understanding the flowchart.
3. The usual direction of the flow of a procedure or system is from left to right or top to bottom.
4. Only one flow line should come out from a process symbol.

or

5. Only one flow line should enter a decision symbol, but two or three flow lines, one for each possible answer, should leave the decision symbol.

6. Only one flow line is used in conjunction with terminal symbol.

7. Write within standard symbols briefly. As necessary, you can use the annotation symbol to describe data or computational steps more clearly.

8. If the flowchart becomes complex, it is better to use connector symbols to reduce the number of flow lines. Avoid the intersection of flow lines if you want to make it more effective and better way of communication.
9. Ensure that the flowchart has a logical start and finish.
10. It is useful to test the validity of the flowchart by passing through it with a simple test data.

Flow Charts

1.INTRODUCTION

The flowchart is a means of visually presenting the flow of data through an information processing systems, the operations performed within the system and the sequence in which they are performed. In this lesson, we shall concern ourselves with the program flowchart, which describes what operations (and in what sequence) are required to solve a given problem. The program flowchart can be likened to the blueprint of a building. As we know a designer draws a blueprint before starting construction on a building. Similarly, a programmer prefers to draw a flowchart prior to writing a computer program. As in the case of the drawing of a blueprint, the flowchart is drawn according to defined rules and using standard flowchart symbols prescribed by the American National Standard Institute, Inc.

2. OBJECTIVES

At the end of this lesson, you will be able to understand:

• the meaning of flowchart
• the basic parts of the flowchart such as flowchart symbols and the flow lines connecting these symbols.
• the advantages and limitations of flowchart

3. MEANING OF A FLOWCHART

A flowchart is a diagrammatic representation that illustrates the sequence of operations to be performed to get the solution of a problem. Flowcharts are generally drawn in the early stages of formulating computer solutions. Flowcharts facilitate communication between programmers and business people. These flowcharts play a vital role in the programming of a problem and are quite helpful in understanding the logic of complicated and lengthy problems. Once the flowchart is drawn, it becomes easy to write the program in any high level language. Often we see how flowcharts are helpful in explaining the program to others. Hence, it is correct to say that a flowchart is a must for the better documentation of a complex program.

4. GUIDELINES FOR DRAWING A FLOWCHART

Flowcharts are usually drawn using some standard symbols; however, some special symbols can also be developed when required. Some standard symbols, which are frequently required for flowcharting many computer programs are shown in Fig. 1

	Start or end of the program
	Computational steps or processing function of a program
	Input or output operation
	Decision making and branching
	Connector or joining of two parts of program
	Magnetic Tape
	Magnetic Disk
	Off-page connector
	Flow line
