INTRODUCTION TO VISUAL BASIC

learn more just click on the image gives..

Visual Basic is one of many programming languages that can be found today. This arises from the language BASIC (Beginner's All-purpose Symbolic Instruction Code) was created in its original version in the Dartmouth College, for the purpose of serving those people who were interested in initiating some programming language. After suffering several amendments in 1978 established the standard BASIC. The simplicity of language won the contempt for advanced programmers as "a language for beginners."

First it was GW-BASIC, Quick BASIC is then transformed into what is now known as Visual Basic and the latest version is 6, which is included in the package of Microsoft Visual Studio 6. This version combines the simplicity of BASIC with a powerful programming language Visual together to develop robust programs for 32-bit Windows. This fusion of simplicity and aesthetics extend much further Microsoft's monopoly, since the language is only compatible with Windows, an operating system of the same company.


Visual Basic is no longer "a language for beginners but is a perfect choice for programmers of all levels who wish to develop applications compatible with Windows.

In this report we explain some terms and / or characteristics of the same order to learn more about this program and handle it with ease

1. Of explaining the basics of programming:

1. What is Visual Basic?

It is a programming language that is designed to facilitate the development of applications in a graphical environment (GUI-Graphical User Interface) like Windows 98, Windows NT or higher.

2. Features of Visual Basic.

Designer data environment: It is possible to generate, automatically, between controls and data connectivity through the action of drag and drop on forms or reports.

The active objects are a new technology for data access through the action of drag and drop on forms or reports. Form Wizard: Allows you to automatically generate forms to manage records in tables or queries from a database, spreadsheet or object (ADO, Active Data Object)


Wizard toolbar is feasible to include toolbars is feasible to include custom toolbar, where the user selects the buttons to be displayed during the execution.

Applications in HTML: directions are combined with Visual Basic HTML code to control events that are performed frequently on a webpage. The Data View Window provides access to the structure of a database. Since this also access the Query Designer and designer of database management and records.

3. List and explain the environment of Visual Basic.

-Title bar displays the name of the project and the form is being designed now q

-Menu Bar: Menu includes off containing all the operations that can be done with Visual Basic 6.0.

-Standard toolbar contain buttons that are used most often when working with a project. Simplifies the choice of menu options File, Edit, View and Run, and it shows in the right location (coordinates) and size of the selected object Window form is the area where the graphical interface is designed, ie, where elected inserted graphics, buttons, images, checkboxes, list boxes, etc..

-Toolbox: presents all controls necessary to design an application, such as text boxes, labels, list boxes, command buttons, etc..

-Project window displays the items involved in the project, such as forms, modules, controls oxc, etc..Each item can be selected independently for editing.

-Window position of the form shows the location that will form on the screen when running the application. This location can be changed if you click with the left mouse button.

-The Properties window displays all the properties of the currently selected control, in this case shows the properties of Form1, then we can see below that says "Form1 Form", which is in bold is the name of the object, and what remains is the type of object, in this case is a form

Formatode storage format

PDF (English acronym Portable Document Format, Portable Document Format) is a document storage format developed by Adobe Systems. This format is a composite (vector image, bitmap and text). It is specially designed for documents that could be printed, since all the information necessary for the final presentation of the document, identifying all the details of how it's going to be, not requiring adjustment of previous processes and layout. Is increasingly being used as specification viewing, thanks to the high quality of the sources used and the facilities for the handling of the document, such as search, hyperlinks, etc..

The PDF file format which means portable document format (in English Portable Document File) is the standard for document distribution and electronic forms. It is a universal file format that keeps the fonts, images, paragraphs and graphics with the look of the source document, regardless of the application and operating system that was used to create it.

Features:

It is multiplatform, it may be presented by the major operating systems (Windows, Unix / Linux or Mac), without modifying either the structure or appearance of the original document.

You can integrate any combination of text, graphics, pictures and even music.

It is one of the most common formats for the exchange of documents. So it is widely used by businesses, governments and educational institutions.

It is an open specification for which they have created free software tools that allow you to create, view or modify documents in PDF format. One example is the office suite OpenOffice.org and LaTeX word processor.

Can be put to protect their content and even digitally sign it.

The PDF file can be created from multiple applications by exporting the file, such as OpenOffice.org and programs can also do with Service Pack 2 (SP2) of Office 2007 Microsoft Office Suite, Microsoft announced to release for some time the first half of 2009 [1].

Is the ISO standard (ISO 19005-1:2005) files to containers of electronic documents in order to preserve long-term [2].

What do I need to view PDF files?

These files are displayed using a freeware product called Adobe ® Acrobat Reader. With this product you can zoom in to see more clearly the contents and print the page designed to respect it. The archives of this site can be viewed from the Adobe ® Acrobat Reader version 3 you

The PDF file format is now one of the most popular, but the original file viewer (Adobe Reader) is a program of significant size and which often requires many resources of our PC. Alternatively we have a file viewer with more light and the basic functions provided by the people of PDF2EXE. This program is compatible with Windows Vista, XP, 2000, 2003 and Windows Server 2008. For more information about it can enter its official website.

Advantage

The main advantage of PDF files that appear when printed on paper as seen on screen. Whenever there is a version of a PDF document we recommend that you use to switch to paper. You can also use it to read. Adjust font size in the most desirable (usually 125%).

to obtain the maximum value of this list of weight using the excel formula = MAX (A2: A13) equals 100.

The Rom

The ROM (read-only memory) or read-only memory is the memory that is used to store programs that start up the computer and perform diagnostics. Most computers have a small amount of ROM (a few thousand bytes). Since the ROM also allows random access, if we want to be precise, the RAM should be called RAM reading and writing, and memory ROM read only memory.
Types of ROM:



There are 5 basic types of ROMs, which can be identified as:

1. ROM
2. PROM
3. EPROM
4. EEPROM
5. Flash memory.

Each type has some special features, but all have one thing in common:

The data are stored in these chips are not volatile, which means you are not lost when the computer shuts down.

The stored data can not be changed or failing to require some special operation changed. Recall that RAM can be changed at the moment.

All this means that by removing the source of energy supplying the chip does not mean that the data is irretrievably lost. ROM operation.

In a similar way to RAM, ROM chips contain a string of rows and columns, but the way they interact is quite different. While RAM uses transistors usually to make way for a trainer at each intersection, ROM uses a diode to connect the lines if the value is equal to 1. Conversely, if the value is 0, the lines do not connect at all.

the algorithms

The story places the invention of algorithms in the ninth century, by work and grace of the astronomer and mathematician Mohammed ibn-Musa andalusia Jwarizmi, hence its name. Development in the Al-Yebra mugabata-ways to allow a limited number of steps and clear indications of execution could solve equations of first and second grade.

From the simplicity of preparing a salad, the possibility of solving a complex problem that concerns us the algorithms are of inestimable help. Obviously this is a modern Trojan horse only shows its efficiency strategic development practitioners, when non-routine situations or even when using the many available algorithms for more complex situations.

It is in this ordered set of steps and limited, which specify the sequence of operations to be solved to solve the problems, which relies heavily on the use of algorithms. We can simply define the algorithms as a set of rules for solving a certain class of problems or as a way of describing the solution of a problem. His character gives the general condition of the algorithms transdisciplinary tool.

It is in this ordered set of steps and limited, which specify the sequence of operations to be solved to solve the problems, which relies heavily on the use of algorithms. We can simply define the algorithms as a set of rules for solving a certain class of problems or as a way of describing the solution of a problem. His character gives the general condition of the algorithms transdisciplinary tool.
And remember not to pass, that the algorithms are at the heart of computers and computer languages that are only half of expressing them. The general expressed above, requires those who seek to produce algorithms to break down problems into simple and concrete, with a limited number of steps in line with the same complexity and the need to make them easily understandable to anyone. It is necessary to clearly explain the order to follow.

As is easy to imagine, the initial step of this process is waived fully understand the problem, requirement to be able to analyze it and then choose the way forward. Once designed and ordered steps, you should opt for a formula or design as that of the flow charts or tables of the decision. The tables are the least used and like so many other things, it originated in the industry (GE), and Feinstein and Holland which introduced in medicine.

As stated above, the flow charts are used, their mission is to graph algorithms, which use a symbol that in practice very few respected but should at least take it into account. A flow is defined as a graphic, clear, concise outline of the sequence of actions needed to solve a problem.

This outline contains the steps of the algorithm, written in symbols, which are connected by arrows indicating the sequence of the flow of data and steps of execution of orders.

Legend of the algorithms

It uses a rounded rectangle for the initiation and completion of the algorithms, the lozenges are used for decisions and rectangles for actions to take. The arrows indicate the flow taking into account that the decisions ¨ no ¨ grow vertically and decisions ¨ Yes ¨ to grow right. While these are not the only symbols, our objectives are regarded as adequate.

One question that is often raised is whether the algorithms are always reliable, a question that deserves concern Renato Cartesius Virtudes
The algorithms give us the opportunity to select what is considered a priority, which is not little and thinking ability as computer starts its first step, which involves precisely defining the problem, which we know is itself a task Intellectual very important.

Printed in addition algorithms, sequential logic and clarity to both systematic processing of data and clinical tests and procedures and this course gives validity by contributing to improve our clinical trial, but even more because we consistently practice can improve care for our patients on many occasions.

There are many computer algorithms based on different degrees of evidence, which provide us with your application and also give us an important resource for research and medical education.

Disadvantages

We can say that among the most important is the ignorance of its existence and does not know its limits. These are possibly the most important, he joined the inability to convert what was stated in algorithms and the lack of availability, because while there is a significant amount of algorithms, for various reasons, only very few are used routinely.

Another drawback to consider is accustomed only to algorithms that are outside and pretend they are not, are not the truth, are just a tool and its efficiency will depend on the use made of it. One detail to consider is the existence of a proposal to establish a center algorithms.

In short we must consider that many of the problems depend on who are unaware of those who do not know their limits and those who overused. If we want greater clarity and recovery algorithms read the most appropriate reference that makes them Komaroff;

.......... while algorithms can play a role in making medical decisions, is unlikely to find a role in two other critically important aspects of patient care .... listen rioja that said, how you say and what is not said, and explain, and show that confidence is a concern. The algorithms are not a substitute for the experience sensitivity or compassion ... In our opinion, the algorithms can help us articulate how we take decisions, to clarify our understanding and to recognize our ignorance. We can help demystify the practice of medicine and to demonstrate that much of what we call the art of medicine is really a scientific process, a science that is waiting to be articulated.

database (access)

What is Microsoft Access.

We can define a Microsoft Access 2000 (the MS-Access or Access) as a system of relational databases, specifically designed for use under Windows 95/98. Consider the meaning of this definition, by describing its components.

What is a database

A database is a collection of information or data related to a particular topic. All who have worked in the archives of an office or consulting a book in a library, we know what a database "on paper", a suitable container (file) where you have a number of cards or sheets reviewed so that they can easily, and usually in a particular order (alphabetical, for example). Each of the cards contain information on a particular item (book, in the case of the library) which are entered in a predetermined and uniform for all of them (author, title, catalog number, topic, number of pages, publisher , date and place of printing, for example). However, the electronic database information is entered, stored and managed by computer programs, among whom Access, object of this course.

Databases and manual files

If we need to locate a book by its title, the cards are in the file alphabetically by title, we will not have to watch every one of the tabs to find it. But if what we want in that file are the books on a particular topic, we will need to review the whole file to find. Referring always to the file manually, could provide a solution to this problem by maintaining a copy of it sorted by subject, by another author, etc. So that we would require the tedious task of updating each of these files since they will a novelty.

Fields, records, tables and bases

A field is the smallest piece of information which comprises a base of data. This part contains a single indivisible data, such as price, size, name, etc..
The fields are arranged in series called records. A record is in electronic storage media, the equivalent of the card. Just as the tabs, each record is composed of the same fields and in the same provision is simply the content remain unchanged but the length and location of each of the data in all records. This collection of identical records in terms of their form in Access is grouped in what is called a table, which is equivalent to the container file or manual. For example, if the third field is the price of registration, all records will contain a table there, different numerical values for the price of each product or item.

The name table is due to their organization in the form of rows and columns.
Each row or line of data contains a single row, arranged side by side, so that, following down in each column we find a particular field of each record in the table. The field names that appear at the top of the table, containing information describing each of them, and serve as a means to reference the data in the field.

What does relational

This term refers to the way it organizes information Access to the various tables that compose a database. The figure below shows the implementation of a relational database system to a customer: We see that in the table of clients many of its fields are encoded, for example, the seller is replaced by the table by a customer number, which is then translated through table sales, the name that appears on the card ( gri sado-box we see in the bottom of the figure). Something similar happens with the province and category of VAT registration. The mechanism of the relationship is simple: just set the same (indicating which fields and which tables are involved) and then automatically have access to related data. For example, with reference to the figure, set the Category field to the table of categories VAT Vend field. Vendors to the table, etc..

Once the above relationships, every time you read a record in the table of customers, are positioned in place all the tables are related.

In the example, simply enter the customer number 249, the vendor table (in the examples loved Commission) will be positioned in "Mario" and the level of VAT on "Registered Resp. We can directly show the name of the vendor rather than your code, something similar happening with the VAT and the province level.
Develop a view of the customer file with all the necessary descriptions. Information obtained through the relationship shown in italics in the gray box of the figure, this type of view of the database will call consultation.

A relational database, finally, is a system specifically designed for the handling of information that has been previously organized in the form of one or more tables.

Creating a database

The first of the alternatives in the table of Figure 1.6 (previous lesson) is to create a new blank database, which is what we will do then.

1. Check the box corresponding to the first option: Access Database blank and click OK. Will now be presented the dialog in Figure 1.7, where we proposed to create a database named db1. This name is currently selected, which means that anything you type will replace the keyboard.

2. Changing the name proposed by a more adequate for our purposes, then write and practice hitting the Create button. Although the word "practice" has no accent is advisable to use it in any case in which we assign names to files, folders, Web addresses and e-mail, etc.., In this way to avoid confusion in future. After clicking Create will be presented on the screen of a window Access very important we work with throughout this course
