Filtering Data Using Control Of a windows From

Filtering Data Using Control Of a windows From
After the data is retrieved from a data source by binding the data to a control of a windows from,you can filter this data to view selective record. This can be done in two ways. First parameterized queries can be passed to filter the data on the basis of a criterion. Second,with the help of controls in a Windows from, data can be filtered to view selective record.
Consider an example, where the sales manager of an organization wants to view the sales information of various stores in a grid format. This data can be displayed by establishing the connection to the database and binding the data by using the DATAGRIDVIEW control.

Querying Databases Using ADO. NET

Querying Databases Using ADO. NET
NET based data-centric application make use of ADO.NET to make connection to a database to retrieve and update data. Depending  upon the requirments,the data can be displayed in a customized formet in a windows application. This customized formet can be displayed by binding data source to a control of a windows from. Such binding of data to a control is known as data binding.

Working With Command Objects

Working With Command Objects
A Command object is a specific command that is used to manipulate data in a data source. It is an object representing a DML statement or a stored procedure that is used to retrieve,insert,delet,or modify data in a data source. A data command is an instance of the oledbcommand OR sqlcommand Class. A data command derived from the oledBcommand class can be used to work with any OLE DB provider,whereas a data command derived from the sqlcommand class can be used to access data from a SQL Server.
To retrieve data by using data commands,first a connectoin object is created to connect to the database from where data is to be retrieved. Then,a Command object is created. To access a data sourse,a data command should provide information about the connection for communicating with the data sourse,the DML statement or the name of the stored procedure to execute,and the parameters that may be required for execution of the data command.
The two type of operations performed by a command object to retrieve and modify data in a data sourse are:
- Synchronous operations
- Asynchronous operations

Useing dvance database features in ado.net

As a programmer ,you need to ensure that your applications are rebates enough to support advanced database operations.THIS MAY ENTAIL STRING and retrieving large-sized objects like image and standred format documents such as xmldocuments, copying hundreds of records from one and ensuring that the cache maintains updated records.you also need to ensure that your application has optimum performance you can do so by usingadvanced database feature in add.net.

Printing And Plotting

One of the most use full and popular forms of output is called hard copy, which
Is simple output paper from a printer. Printer with different speed, feature and capabilities are available. Some can be set up to accommodate different paper forms such as blank check forms, invoice forms and so forth. Newer printers allow businesses to create customized printing output for each customer from standard paper and data input using full color.
The speed of the printer is typically majored by the number of pages printed per minute (PPM). Like a display screen, the quality, or resolution, of a printer’s output depend on the number of dots printed per inch. A 600-dpi (dots per inch) printer print more clearly and a 300-dpi printer. A recurring cost of using a printer is the ink-jet or laser cartridge that must be replaced every few thousand of pages of output.
Plotters are a type of hard copy output devices are used for general design work.
Businesses typically use these devices to generate paper or acetate blueprints,
Schematics, and drawings or new products onto paper or transparencies. Standard plot widths are 
24 inches and 36 inches, and the length can be as per the need-from a few inches to feet. 

Evolution of operating systems

Early computer were capable of performing only one job or task at a time.this from of computer opertaion is often called single-user batch processing.the computer runs a single program at a time while processing data in group or batches.In these early system,users generally submitted their jobs to the computer center on desk of punched cards.Users often had to wait hours or even days before printouts were returned to their desks.software system called oprating system were devloped to help make it convenient to use computer.Early operating systems managed the smooth transition between jobs.This minimized the time it look for computer operator to switch between jobs,and hence increased the amount of work,or throughtput,computer could process.As computer became more powerful,it became evident that single-user batch processing rarely utilized the comuter's rwsourcess efficiently.Instead,it was thought that many jobs or task could be made to share the resources of the computer to achieve better utilization.This is called multiprogramming.Multiprogramming involves the "simultaneous" operation of many jobs on the computer-the computer share its resources among the jobs competing for its attention.With early multiprogramming operating system,users still submitted jobs on decks of punched cards and waited hours or days for results.In the 1960s,several groups in industry and the universities pinoeered timesharing operating systems.Timesharing is a special case of multiprogramming in which users access the computer though terminals,typically devices with keyboards and screens.In a typical timesharing computer system,they may be dozens or even hundredsnof users sharing the computer at once.The computer does not actually run all the users simultaneously.Rather,it runs a small portion of one user's jobs and then moves on to service the next user.The computer does this so quickly that it may provide service to each user several times per second.Thus the user's programs appears to be running simultaneously.An advantage of timesharing is that the user receives almost immediated responses to requests rather than having to wait long periods for results as with previous modes of computing.

How to Mention A Resume Uploder Option In A Html Site

Hey Guys When we visit some web sites they show a pop up box to register and uplod your resume and detail .

So today I tell you how to mention that type form on your website for visiters.

<html>

<body>

<form name=”uploder”>

Our name : <input type=”text” size=”30” name =”fulname”>

Your file:  <input type=”file” size=”20” accept=”audio/video/image”>

<input type =”submit”>

</form>

</html>

IN “Your file:  <input type=”file” size=”20” accept=”audio/video/image”> SECTION YOU SEE A OPTION AUDIO/VIDEO/IMAGE YOU CAN USE ONE OPTION OR ALL .

BECAUSE IF U USE ONE OPTION LIKE IF YOU USE   Your file:  <input type=”file” size=”20” accept=”audio>

THAN VISITER WHO TRY TO SUBIT HIS/HER RESUME WITH YOUR WEBSITE ONLY UPLODE AUDIO FILE IN RESUME.

IF YOU WANT TO GIVE ALL OPTION THAN USE AUDIO/VIDEO/IMAGE .
