Visual Basic Useful Programming Codes – Top Tens List!

What is Visual Basic? To put it in simple terms, visual basic is a software designed by Microsoft which allows programmers to create their own software. It is a great program to practice on for amateur programmers and can yet be very powerful if used appropriately. Today we thought we should make a list on something related to visual basic just because it’s so awesome; so without further ado, the following is the list to The Top Ten Most Useful Visual Basic Programming Codes:

#10: (Form name).Show

This visual basic code simply opens up a form when a specific function is performed by the user. For example, let’s say a programmer wants a form to pop-up when a user clicks on a button, all the programmer has to do is to double-click the button, and insert the code, (Form name).Show and it will open the form with the corresponding name.

#9: Math.(function) (number)

This code in visual basic programming simply fulfills a few of many math functions. Just type the word Math. and a list of options should open in a dropdown menu. Some examples include; Math.Round(number, spaces to round) – This simply rounds a number to specific number of decimal places, another example is, Math.Log(number) – This simply applies the logarithm function to a number.

#8: Arrays

Arrays in visual basic are basically used to store multiple data. For example, if a programmer wants to store the numbers input by the user, all the programmer needs to do is create an array to store those numbers. To create an array simply type the code, Dim (array name) (size of array) As (type of data stored in array; for example, integer, string, etc.).

#7: Erase

The Erase function in visual basic simply clears or erases certain data. For example, if a programmer wants to erase everything stored in an already created array, simply type the code, Erase (array name).

#6: Do…While Loops

Loops are visual basic codes that tell the computer to keep repeating the same code until something specific happens (set by the user). Do…While loops simply tell the computer to repeat a certain code as long as the conditions are met. The format for Do…While loops is, Do While (condition)…(code to repeat)…Loop

#5: Randomize

Randomize is a built in visual basic function which along with the Rnd(number) function can generate random numbers between a specific range which can be displayed or stored in a variable. The format of the code is, Randomize()…(an integer variable) = Int(Rnd() * (largest number)) + (smallest number)

#4: For…Next Loops

Loops, as explained earlier, are visual basic codes that tell the computer to keep repeating the same code until something specific happens (set by the user). For loops simply repeat between a certain range of things until the output is out of range. The format of the code is, For (variable) As Integer = (starting number) To (ending number)…(code to repeat)…Next.

#3: If…Then…Else Statements

This code in visual basic programming is probably one of the most essentials for any programmer to know. An If…Then…Else statement basically tells the computer to do something if a certain condition is met and the Else part tells the computer what to do otherwise. The format for the code is, If (condition) Then…(code to execute)…Else…(code to execute)…End If. An ElseIf statement could also be put inside in an If…Then…Else statement which is almost the same thing as adding another If…Then…Else statement except for a few exceptions.

#2: Close()

This code is probably quite self-explanatory but just in case, we’ll explain it anyway. The visual basic code Close() basically directs the computer to close the program when executed and that all there is to it. It might be small but as they say, “big things come in small packages.”

#1: Dim Statements

This code is THE MOST essential thing to know while programming in visual basic, simply because it is the starting point of 99% of the programs. So, what is dim? The “Dim” in Dim statements stands for Dimension and its commonly used to introduce variables, specify the type of variable and set the value of the variable. The format of this code is, Dim (variable name) As (variable type; such as Integer, String, etc.) = (variable value).

Note: The “…” between code lines simply means that the code after the “…” is on a new line.
