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.

What is a For Loop? A For Loop is used to iterate through a script a certain amount of times. Personally, I use it to check conditions for each item within a group, list or array. How do I use a For Loop? To create a For Loop you first need to decide how many times you want a script to run.

What are 'Arguments'? In programming, arguments are pieces of data which are sent to a function upon calling that function. Arguments can be any standard variable type, this includes types such as 'String', 'Integer' and 'Boolean'. What are 'Parameters'? Parameters (Params) are the pieces of data which are request or required once a function has been called.

What are custom functions? Custom functions are functions which you have made yourself. They can be Private (only the class in which it is created can use it) or Public (any class may use it). They are able to take parameters/arguments, can return data and can be ran on separate threads. When should you use custom functions? Whenever you have a script which needs to be ran over and over again at different positions within your source code you should create one function to contain the script.
