Understanding Static Control Is Vital To Development Procedures

By Leslie Ball


The Windows API is a set of application programming interfaces and is available in all the Microsoft Windows operating systems. These are many different platforms of implementations which carry out certain actions. One of them is static control which can be used to display texts and visual features.

This is a way of controlling the systems that allows the user to use a certain application to provide them with informational diagrams and illustrations as well as texts. These generally do not need to be responded too. Any application that used this system will be able to control other groups of controls or single ones. They are often referred to as child windows.

This will receive information from the mouse which will intern notify the parent window as to when the person using it will click or double click the option. These can be used in pop-ups and overlapping but their main purpose for design is to be used in dialog boxes where the system will remove any irregularities and variations in their behaviour. If they are used outside of the dialog boxes there is an increase in risk that they will behave in a different way.

A kernel is a program that manages the input and output that is requested from the software and then changes them into data. There is a code for this and is loaded into an area that is protected and cannot be overwritten by any other part of the operating system or programs. It handles all interruptions and prevents the user data and kernel data from mixing with one another and therefore ensures that the system does not crash.

The next is the Text control and it can display texts in five different styles also in a rectangular shape. It will command the computer to left-align without or with a word wrap as well as centre and right align as well. It will also display the simple text which cannot be re-arranged unlike the before mentioned ones.

The fonts are also controlled by this and many people get confused as to what the difference is between the typeface and a font. A typeface can be described as many metal blocks each with a character of a key design. A font is a block that has a certain weight and size to it. Over the years the fonts where no longer many blocks and became digital computer files that changed to whichever the user wanted.

The CPU or central processing units main responsibilities are to run programs. The kernel will decide which of the programmes should be allocated to the processor. These are usually only able to run one program at a time. The casual access memory is where the programs data and instructions are stored. These both need to be in the memory so that programs can be used.

Each height of the characters is measured in points and each is about one of a seventy two inch. In order for each character to fit into a certain space it is measured by pitch. The most common are ten and twelve but can be much larger when needed for posters and presentations.
