Variables - Getting and setting values

James Crowley

Getting and setting values

To set the value of a variable you use the following syntax:

VariableName = Value

Where VariableName is the name of the Variable, and Value is the value to be stored. An error will occur if Value is not the correct datatype for that variable.

' General Declarations Section
Dim NumberofEmployees As Integer
' Form Load Procedure
Sub Form1_Load()
    ' Set the variable value
    NumberofEmployees = 150
End Sub

This sets the value of NumberofEmployees to 150 when Form1 Loads

To get the value contained in a variable, you simply put the variablename in place of where you would otherwise type the value:

' General Declarations Section
Dim NumberofEmployees As Integer
' Form Load Procedure
Sub Form1_Load()
    ' Set the variable value
    NumberofEmployees = 150
End Sub
' Command Button1 Procedure
Sub Command1_Click()
    Msgbox "The number of employees is: " & NumberofEmployees
End Sub

The previous code displays a message 'The Number of employees is 150' when Command1 is clicked.

James first started writing tutorials on Visual Basic in 1999 whilst starting this website (then known as VB Web). Since then, the site has grown rapidly, and James has written numerous tutorials, articles and reviews on VB, PHP, ASP and C#. In October 2003, James formed the company Developer Fusion Ltd, which owns this website, and also offers various development services. In his spare time, he's a 3rd year undergraduate studying Computer Science in the UK. He's also a Visual Basic MVP.

    Hey cwamsley,

    Welcome to DevFusion!

    This sounds like a control array problem - if you're using VB (and not .NET) that is. You can have several controls with the same name, but with an index, lik...
