Inside the Private Sub cmdShow_click() procedure. This code will be executed when user clicks Show Message Command button.

Your hello world application is ready to run. Select Run icon from main tool bar.

Visual basic prompts you to save project.

Save all project files in the start_vb folder

When you saved project, Hello World form displays. Click Show Message button. Message displays

Congratulation. You created your first Visual Basic application.
How it works?

Execution starts from sub main procedure. This procedure is defined in module as a public. It means the procedure has global scope. The code inside the sub main procedure is

frmMain.show.

frmMain is a name of the form.

Show is its method or function. When show method is executed the form displays.

When user clicks the Show Message button, button click event occurs. On button click event cmdShow_click procedure is executed. The code inside cmdShow_click procedure is

lblMessage.Caption = "Hello World!"

lblMessage is a label name. Caption is a label property. When code is executed, the string "Hello World" is assigned to label caption and is displayed on the label. The label background color, font and font color are label properties and can be set in the properties window or by code.
