MsgBox “” vs MsgBox() in VBScript

Question

I\'m trying to write a VBScript and I\'m using functions such as Randomize, and MsgBox. I\'m curious as to what is the difference of using () and not using them. For example

Answer 1

The difference between "" and () is:

With "" you are not calling anything.
With () you are calling a sub.

Example with sub:

Sub = MsgBox("Msg",vbYesNo,vbCritical,"Title")
Select Case Sub
     Case = vbYes
          MsgBox"You said yes"
     Case = vbNo
          MsgBox"You said no"
 End Select

vs Normal:

 MsgBox"This is normal"
