Windows Applications & Computer Programming Now a day’s computer is almost completely involved in our lives. Mostly people don’t know how computer works and computer programming because they don’t need to know about it because now a day’s software’s and application interfaces are extremely user friendly and user can easily understand how to use it. At the backend a software developer or a programmer has to write a program to make it easy and user friendly so a front end user can use it. In computer programming we write instructions and set of instructions for computer which could be understood Read More …

Nested If Then Else Structure Visual Basic 6.0 – 11th tutorial

visual basic tutorial

Nested If Then Else Structure lets take a look at nested if then else structure in visual basic. When we compare condition while staying in a condition comparison or we create a if structure within an if structure is called nested structure. A condition located inside a condition is called nested condition. When programming logics clear first step and again have to execute a condition we can handle it using nested If then else statement. Every nested statement closes itself inside the parent statement I mean outer statement. And can have its own complete parameters including else too. While in Read More …

Compound comparison Visual Basic 6.0 – 10th tutorial

visual basic tutorial

Compound Comparison and Conditional Statements To compare more then one condition or we have to use multi conditional structure is called Compound Comparison. Its used to execute set of statements by testing many conditions. As we learnt about extended if then else structure in our previous lesson here is almost same thing but we can say it’s little bit more advanced and also complicated. Or we can say here is something to decision making in our program logic. We can face many conditions at same time and have to handle them using few logical operators. While using if statements we Read More …

Extended if then else structure in Visual Basic 6.0 – 9th tutorial

visual basic tutorial

Extended if then else structure To chose a block of statements form many options we can use extended if then else structure. We can chose from many options using one condition parameter. If we have a condition again inside a condition we can extend its functionality using Extended if then else structure. For example if we have multiple type of users login some users are just common users and some have access to see reports and some maybe system administrators. I mean users with multiple access levels. To manage and handle situations like this we can use extended if then Read More …

Conditional statements in Visual Basic 6.0 – 8th tutorial

visual basic tutorial

Conditional statements Conditional statement mean a set of instructions will be executed when a predefined condition occurs. For example if you want to show pass if student get  33 or more then 33 marks. Or show failed if student got less then 33 marks. Here you have to write conditional statement. While working on a software application project we have to face many conditions appeared in program logics. This is beauty of programming that can be used to check and set conditional execution. Let’s get one more example to know what a conditional statement is and how it works. Imagine Read More …

Variables in Visual Basic 6.0 – 7th tutorial

visual basic tutorial

Variables in Visual Basic Lets start creating variables in Visual Basic. Variable is a temporary memory location stored in computer RAM which we can use for different operations. We can create many variables according to our requirements, we can store data and retrieve data from a variable using variable name. As we know data in variable is stored in computer RAM so its temporary data it can be used only in respective program and data will be removed automatically when a program ends. Data in a variable can be changed during program execution any time when a change required. We Read More …

Programming fundamentals in Visual Basic 6.0 – 6th turorial

visual basic tutorial

Programming Fundamentals Programming fundamentals are almost same in every language. Program is a set of instructions written in any language that can me executed for any specific operation. Programming fundamentals about visual basics are actually related to keywords and syntax of code etc. Its very important to type right syntax in source code even we cant add a simple dot or dash in source code by putting aside basic syntax. We have to program exactly as the programming syntax is. If we don’t care about syntax and keywords our code will not work properly and also will generate run time errors. Read More …

Control management in Visual Basic 6.0 – 5th tutorial

visual basic tutorial

Control management Control management in Visual Basic 6.0 is very easy. There are many controls in visual basic to develop  and create better and responsive applications. Controls are also known as tools, components, or objects. We can use any control as our requirement to design user interface for a specific application. Just using drag and drop method its beauty of visual basic we can insert controls to our interface just by dragging them into our interface. control management is about managing controls to interface in a right way What the Controls are? Basically controls are for users placed at user Read More …

Methods and Objects in Visual Basic 6.0 4th tutorial

visual basic tutorial

Methods and Objects Methods and Objects are predefined working for a control. Each method have its own properties and code procedure. These codes are executed when user invokes a method. Its known as Method Call. Methods and Objects are very important to use when creating an event driven program. Visual Basic is an event driven language. Event driven mean our code or software will work only when a specific event will occur. We define these events while coding the application as applications requirements. Let me tell you in little bit details about methods and objects. Actually when you click on Read More …

First Hello World Program using Visual Basic 6 3rd tutorial

visual basic tutorial

Hello world program Using the following example we will create our first hello world program. So lets start learning our first simple application. We will show Hello World in a message box. Purpose of this program to understand and getting idea how basic controls works and how we can use simple coding in Visual Basic. We will setup few very basic controls and assign properties like size, caption, and events. then we will write a little piece of code to make it working. Its very simple and basic application program which every programmer creates as his first project to say Read More …
