When using Trim, make sure you don’t run into common errors that may come up. where the original value of mystring was ” Hello “, the new value of mystring will be “Hello”. Removes leading and trailing spaces from a stringĮ.g. where the input mystring is “Welcome”, the output mystring will be “come”įor more info about substring functions, see our article here. MsgBox "Last four characters of your input are " + mystringĮ.g. Returns a given number of characters from the right-hand side of a string where the input mystring is “Welcome”, the output mystring will be “Welco” Right MsgBox "First five characters of your input are " + mystringĮ.g. Returns a given number of characters from the left-hand side of a string if Mystring is “Welcome”, length will be 7. MsgBox "The length of the string is " & lengthĮ.g. Mystring = InputBox("Enter a string to get the length") Returns the length of a given string or 0 for Empty.

Returns a string character that corresponds to the ASCII code in the range 0-255. For example if you have a problem with letter “H” on your keyboard, knowing that the ASCII code for “H” is 72 as seen in the example above, if you type ALT + 72 on a word processor or an IDE editor, that will give you letter “H” (or Alt + 104 for “h”). Note: This command can be useful when you have a problem with a key on your keyboard. MsgBox "The ASCII code is " & amp amp amp code

Write the following code in the “ Form_Load” procedure that was created when you double-clicked on the form in the previous step.

Double Click on the default form that has been created automatically in the project.

Create a new project in your VB IDE (VB6 or VB.NET).

In the other examples we shall give only the expected outcome. The screenshot will be done just for this example. The code will be written in an old version of a Visual Basic IDE (VB6) and a new version (VB.NET). In this example we are going to look for the ASCII (American Standard Code Information Interchange) code of the first letter of the word “Happy” hoping that you are happy reading this article. String refers to the string containing character as first letter whose ASCII code is to be found. Returns the number corresponding to the ASCII code for the first character of string Few of them will be studied here just for the purpose of understanding how they function. In Visual Basic programming there is a multitude of commands and it will not be possible to list all of them in this article.

In this article, you are going to learn more about Visual basic commands and how to use them in your code. Visual Basic, like any other programming language, employs commands. Differences in the names and use of different commands are essentially what make one programming language different from another.Īs a programmer, you may be able to accomplish the same task coding in either Python or Visual Basic, but the code involved would be completely different between the two projects because of the way each language defines and interprets commands. Unlike variables, which are named and defined within your code, command names are defined by the programming language itself and cannot be changed. When referring to a programming language, a command is a unique word/keyword used to perform a specific operation. If the operator entered is incorrect, an error message is displayed.A command is a specific instruction given to a computer application to perform a task or function. The code snippet that demonstrates this is given as follows − double num1 Ī switch case is used to perform the specified operation on the two numbers. The two numbers as well as the operator is acquired from the user. ("\nEnter an operator (+, -, *, /): ") ĭefault: ("Error! Enter correct operator") A program that demonstrates this is given as follows − Example import A basic calculator is able to add, subtract, multiply or divide two numbers.
