4.13. Modules

Visual Basic application source code is structured

into module files with a .vb suffix. By default, Visual Checkpoint
Studio creates a separate module file for each form Decision making statements,

in an application containing the code to construct give different results for different Developing Applications
inputs.
the form. For example, the code to create a form Loops allow a sequence of
instructions to be repeated until
called Form1 will be placed in a module file named a certain condition is reached.
Form1.Designer.vb. Similarly, any code that has

been defined by the developer to handle events from controls in the form will be
placed by Visual Studio into a module file called Form1.vb. Using modules in VB

are recommended while creating a complex application as they save space in
your code and also assist to reuse of code like functions.

Follow the steps below to create using modules:

1. Create a form with one text box and
a button and change the text to

“Code from Module”.
2. Right-click on the project from the

solution explorer window and go to
Add and then go to Module and

click
3. In the next window Module will be

automatically selected give the
name to Module or just click on

Add.
4. After that, you will see the Module1.vb will start appearing in the solution explorer

window and the script window of the module will also open.
5. In between the Module and End Module lines, we will add our Subroutine.

6. Using an element from another form in a module requires a declaration with the
name of the form. In this case Form1.TextBox1 is the name of the element from the

other form and its text will appear in the vbinformation box with the title defined as
a string.
