If statements

In Visual Basic, the If statement executes a block of code if a condition is true. The basic syntax of an If statement in Visual Basic is as follows:

If condition Then
   ' code to execute if condition is true
End If

For example, the following VB6 code checks whether a number is positive:

Dim test As Integer = 12
If test > 0 Then
   MsgBox ("The number is positive")
End If

You can also use an Else statement to execute a different block of code if the condition is false. The basic syntax of an If-Else statement in Visual Basic is as follows:

If condition Then
   ' code to execute if condition is true
Else
   ' code to execute if condition is false
End If

For example, the following VB6 code checks whether a number is positive or negative:

Dim test As Integer = -12
If test > 0 Then
   MsgBox("The number is positive")
Else
