In Visual Basic, we are using Conditional Operators to evaluate a condition that applied to one or two boolean expressions. An expression returning a value if the that expression is true and a different one if the expression is evaluated as false. The logical AND and OR operators both take two operands. Each operand is a boolean expression.

One module in Visual Basic is DateAndTime . Which contains date values, time values, or date and time values. As a programmer, there are cases that we always display the date and time in our application or web application. Using visual basic we can manipulate dates and times in many ways. To do this, open and visual basic and create a new project and save it as “Datetime”.

One way to loop over the elements in an array using visual basic is to use For each loop. Because it automatically loops over all elements in the array or collections. And it works well when you can associate each iteration of a loop with a control variable and determine that variable’s initial and final values.

In programming, there are many cases that we need to reuse or we want to store many values in a single variable, but the problem is that variables can only hold one value. On the other hand we will be using an array. An array is a series of objects, with the same type and size. Each object in an array is called an element of an array.

Progress Bar is used to give visualization about the status of the current process and computer operation, such as a downloading , transferring of files, installation and more. Your application will look more professional if you are implementing a complex data processing using the Progress Bar. This time, we will create an example of a Progress Bar using Visual Basic. First, open visual basic and create a new project then, save it as “ProgressBar”. Then from the toolbox add a progressbar,label, button and a timer. Next, we’re going to add functionality to our application.

In programming, the Mathematical operations are very useful because most of the time we are dealing with mathematical concepts in programming. We know that computers can perform a mathematical calculation much faster than humans. Also the computer doesn’t have the capacity to do calculations without receiving any instructions from the computer user.
