Exiting an If statement

[ninelgorb]

I know there is an EXIT for a Do, For, etc Loops, but is there something to exit an IF statement?

Thanks,
Ninel

Yes, it's called a nested IF... ;>)

Errr. ?

if/then statement is not a loop so if the expression if false it exits...

If <Expression> Then
' code for true value
Else
' code for false
End If

err, why not block if the remainder?

if Condition1 then
  'do thing

  if Condition2 then
    'do other thing
  end if
end if

Or, you can throw an exception. I use this if I'm validating data before running a block of code:

try
  'do thing

  if NoDataFound then
    dim excNoData as New Exception("No data found")
    throw excNoData
  end if

  'do other thing

catch exc as exception
  'handle exception
end try

And finally, yes, the GOTO statement still exists. But I am fundamentally opposed to it's continued existance, so I will not go into it.

That being my point.

If the expression is true you proceed to process the code.

However, if further in your code you come across a reason for 'exiting' the IF, well, then you use another IF. This gives you the option to process or not whenever / wherever you want.
