Conditional statements are used to perform different actions for different decisions.
In VBScript we have four conditional statements:
Use the If...Then...Else statement if you want to
If you want to execute only one statement when a condition is true, you can write the code
on one line:
There is no ..Else.. in this syntax. You just tell the code to perform one action if a
condition is true (in this case If i=10).
If you want to execute more than one statement when a condition is true, you must put each
statement on separate lines, and end the statement with the keyword "End If":
There is no ..Else.. in the example above either. You just tell the code to perform multiple
actions if the condition is true.
If you want to execute a statement if a condition is true and execute another statement if the
condition is not true, you must add the "Else" keyword:
In the example above, the first block of code will be executed if the condition is true, and the
other block will be executed otherwise (if i is greater than 10).
You can use the If...Then...ElseIf statement if you want to select one of many blocks of code to
You can also use the "Select Case" statement if you want to select one of many blocks
of code to execute:
This is how it works: First we have a single expression (most often a variable), that is
evaluated once. The value of the expression is then compared with the values for each Case in
the structure. If there is a match, the block of code associated with that Case is executed.
