Windows Server 2008 : Creating Basic Visual Basic Scripts - Using if Statements, Checking for a Value with a Message Box

1. Using if Statements

You can use if statements to add choices to your script. The if statement tests for a condition, and when the condition is true, it takes the specified action. The basic syntax is

if condition then action

You can also add else and elseif statements. If you add else and elseif statements, you must end with an end if statement. The extended syntax is

if condition then action
  elseif condition then
     action
  else condition then
     action
endif

The following section shows how to use the if elseif statement block to check which button a user pressed from a message box.

2. Checking for a Value with a Message Box

You can identify which button a user presses by checking for a value after the message box is dismissed. The following code shows a basic check:

intbutton = msgbox ("Do you want to continue", vbquestion +
vbyesno,"Question")
If intbutton = 6 then
   msgbox "User pressed Yes",,"Answer"
 elseif intbutton = 7 then
   msgbox "User pressed No",,"Answer"
end if

intbutton = msgbox ("Do
you want to continue",
vbquestion + vbyesno,
"Question")

If intbutton = 6 then
   msgbox "User pressed
Yes",vbokonly, "Answer"
 elseif intbutton = 7 then
   msgbox "User pressed
No",,"Answer"
end if
