“An HTML form is a section of a document containing normal content, markup, and special elements called controls.” These controls are commonly referred to as input controls, according to the World Wide Web Consortium. There are many types of input controls that can be used in a web form. They help to provide a framework for the kind of data that will be submitted by users. Selecting the correct input control for a data field is critical.
Text input, select box, radio button, and validation are four examples of input controls. As pointed out by Ponce de Leon, most input controls are visual and interactive. There is also something called a hidden input control. They can be used to store system critical data, such as database key data, that the user does not need to interact with.
Text type input controls are used to input text. They provide a single-line input field in which any text can be entered. The text type input controls are useful for form data such as names, street addresses, and user names. This data is viewable on the screen, so it ought to not be used for passwords. One type of input control is the standard text box. The text box can display messages or provide a place for the user to enter data. The text box is used when the system requires the user to type information such as city names, airport codes, or web page addresses. When using a text box, it is often helpful to use an auto complete function to help ensure proper data entry. This would be beneficial when the number of choices are too numerous to be displayed in a drop down list box. The data integrity error that is possible from using a text box is almost always going to occur due to human error. If the text box is programmed to accept letters (i.e. Name) and the user inserts a number, this will result in a data integrity error.
Another type of input control is the previously mentioned…...

...Abstract Input controls are an integral part to any form. Input controls allow users to perform a variety of functions to ensure that input data is correct complete and secure. “Data input controls ensure the accuracy, completeness, and timeliness of data during its conversion from its original source into computer data, or into a computer application. Data can be entered into a computer application from either manual online input or by scheduled automated processing. The input control reviewer should determine the adequacy of both manual and automated controls over data input to ensure that data is input accurately with optimum use of computerized validation and editing and that error handling procedures facilitate the timely and accurate resubmission of all corrected data.” (Audit and Management Advisory Services, 2012) also instruct users that input edits should be used with a form or computer application, these input edits range from checks for invalid field lengths, invalid characters, missing or erroneous data, and corrected dates, or the use of check digits. Input data should also be controlled by the use of record counts, control totals, and event logs. The duties of input controls are to ensure data entry through authorization; in addition, these duties should be separate to ensure that no one individual input control performs multiple critical tasks.  User interface (UI) design is the first task in the systems design phase of the SCLD. One element of the UI......

The remainder of this report describes an implementation of an algorithm which, given a suitable representation of a QT, optimizes according to the above heuristic rules. 2 Implementation The implementation of the heuristic optimization is done here in multiple passes. This modularity between the steps of the algorithm makes it easy to replace one or more of the existing routines with a user-supplied routine, such as might be done in an academic setting. The command line interface to the program is as follows: % Query !input file? !output file base? !input file? is the name of the input file containing the QT ...

...Assignment 3: Input Controls CIS 210 – Systems Analysis and Development Ibrahim Elhag Marc Espos November 12, 2013 In the realm of input security and control, input controls allow users to perform various commands to ensure that the date is correct, complete, and cohesive. When data is entered from an application or automated process, the computer can produce an input log file that identifies and documents the data entered. As a system analyst must determine the importance of automatized and manual controls over data being transpired. Another important aspect a system analyst must determine is to promote data accuracy and quality. Overall the main purpose of this system is to serve as a checkpoint towards ensuring that the data is entered into the system correctly. One thing to consider is that there are numerous types of input controls. Also that most input controls are designed to be visual and interactive. Some of these input controls are: text boxes, drop-down list box, input masks, and validation rules. The first input control is text boxes. The standard textbox displays messages or provides a place for a user to enter data. These messages usually include entities of zip codes, addresses, cities, numbers, names, and serial codes. Once a form is submitted, a script can change the structure of a textbox. When designing a text box, the designer should implement the function called auto complete function. The purpose of......

...Input Controls Assignment 3 Roseana Clark | CIS 210 Professor Nancy Romero | 11/15/2014 Application controls are used to refer to transactions and any data that relates to the computer based application system. They should be kept specific to each application. Application controls may be manual or programmed, but are necessary in the support of record accuracy as well as data validity. These controls are used in processing, output and input. The application controls will ensure the data is complete, accurate, and valid. This is where input controls assist in maintaining these goals. An input is a graphic the server displays with the report. The function of the input control will support the data is complete, accurate, and valid. The procedures include asking the user for input, validating its format, and then passing it to the report. When you create and name an input control, you would assign a predefined data type for the user to enter. The data types will define the input, as well as any restrictions the server enforces. The server uses the predefined data type to classify and validate the data. If the data type is named and the server cannot find a parameter by the same name, when the report runs, the input control will not function. Input controls are an essential part to designing a form. They will allow the user to perform any input functions. These functions may include typing in text, or to select items from a list, or even uploading a file. ......

...Input controls Computer input devices provide users with the ability to control hardware and software functions. Input devices also pass data to the computer. This data can come in many forms, including text, images and audio. There are a lot of input devices you can use with a computer, but they all tend to perform a similar set of functions. Understanding input functions is not typically difficult and is key to understanding how computers work generally. At the most basic level, an input device is for passing data to a computer system. The most basic forms of input commonly used with computers therefore include portable disk drives and CDs. Portable storage devices such as external hard drives and USB memory sticks store various types of data, contained within digital files. When connected to a computer, these can act as input devices, allowing users to copy files onto the computer system. The keyboard is one of the most frequently used computer input devices. Keyboards are connected to PCs through cables or built-in to the same hardware item in cases such as laptops. Users can input text using their keyboard for functions such as word processing, emailing and carrying out Internet activities including entering website addresses, performing searches and emailing. With tablet PCs and touchscreen smartphones, users enter text using the screen, which acts as both an input and output device.

Assignment 3 Input Controls

...According to Ventureline.com input controls are computer controls designed to provide reasonable assurance that transactions are properly authorized before processed by the computer, accurately converted to machine readable form and recorded in the computer, that data files and transactions are not lost, added, duplicated or improperly changed, and that incorrect transactions are rejected, corrected and, if necessary, resubmitted on a timely basis (www.ventureline.com). The use of input controls should never be overlooked. Input controls are a great way to deliver high quality implementation as a control, which will also deliver high quality output results. Each system respectively may have different needs for different input controls, but regardless of the specific purpose that is possible for any system the aspects that relate to input controls will affect both user and technical areas of the system. When users are interacting with a system they are concerned with the usability and accessibility if the system while designers are concerned with the validity and accuracy of the information being inputted. Input controls are a valuable tool, some input controls may implement certain test procedures in order to validate and verify entered information and depending on how the program is configured there may be either a recommendation presented to the user or an automatic process carried out to utilize the input controls. One type of input control is a validity check.......

Input Control of Android Platform

... Input Controls Input controls are the interactive components in your app's user interface. Android provides a wide variety of controls you can use in your UI, such as buttons, text fields, seek bars, checkboxes, zoom buttons, toggle buttons, and many more. Adding an input control to your UI is as simple as adding an XML element to your XML layout. For example, here's a layout with a text field and button: ------------------------------------------------- <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"     android:layout_width="fill_parent"     android:layout_height="fill_parent"     android:orientation="horizontal">     <EditText android:id="@+id/edit_message"         android:layout_weight="1"         android:layout_width="0dp"         android:layout_height="wrap_content"         android:hint="@string/edit_message" />     <Button android:id="@+id/button_send"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:text="@string/button_send"         android:onClick="sendMessage" /> </LinearLayout> Each input control supports a specific set of input events so you can handle events such as when the user enters text or touches a button.

...Running head: Input Controls Input Controls Tynisha Ellis Dr. James Francisco Systems Analysis and Development February 12, 2012 Abstract A company must do everything in its power to protect its data. This includes not only the firm’s own information, but that of its customers, employees, and suppliers. In this paper I will be describing four types of input controls, in user interface design, and their primary functions. Input control includes the necessary measures to ensure that input data is correct, complete and secure (Rosenblatt & Shelly, 2012). Some examples of input controls are audit trails, encryption, password security, and data security, just to name a few. Input Controls To begin, audit trails record the source of data each data item, and when that data enters the system (Rosenblatt & Shelly, 2012). It is a series of records of computer events, about an operating system, an application, or user activities (Gopalakrishna, 2000). It is generated by an auditing system that monitors system activity (Gopalakrishna, 2000). Audit trails have many uses in the realm of computer security (Gopalakrishna, 2000). The uses include: 1. Individual Accountability: A users actions are monitored and tracked giving them accountability of their own actions. This deters users from evading security policies and even if they do evade them, they will definitely be held accountable (Gopalakrishna, 2000). 2. Reconstructing Events:  Audit trails......

...Assignment 3: Input Controls and Restricting User Interface INPUT CONTROLS No matter how data enters an information system, the quality of the output is only as good as the quality of the input. When developing or purchasing a new system or application, it is important that the system or application has adequate input controls. “Input controls ensure the complete and accurate recording of authorized transactions by only authorized users; identify rejected, suspended, and duplicate items; and ensure resubmission of rejected and suspended items (Understanding Internal Control).” These controls are critical because a large number of errors in computer systems are the results of input errors. “Input controls will ensure that data is accurately processed through the application and that no data is added, lost, or altered during processing (Hall, 2011).” There are several types of input controls for an input design such as check digits, reasonableness checks, validity checks, and batch total control. In this paper, I will discuss these input controls more in detail. When human beings use numbers - whether keying them into computers, dialing them on telephones, or reading them and telling them to others; they tend to make certain kinds of mistakes such as entering an incorrect digit, changing the order of successive digits, or adding additional digits. These types of simple mistakes are known as transposition and transcription errors. Check digits are an input......
