Cannot get simple IF - ELSE statement to work.

[wisem2540]

I am trying to do something like this...

$var = Regread($Value)



If @Error < 0 Then Msgbox(0,"test", "Does Not Exist")

Else

Msgbox(0,"test", "Does Exist")

But everytime I do, it tells me I cant use ELSE without a matchinf IF statement. Why does this not work?

If you are using an If statement with more than one possible result, you have to write it like this.

$var = RegRead($Value)

If @error < 0 Then
    MsgBox(0, "test", "Does Not Exist")
Else
    MsgBox(0, "test", "Does Exist")
EndIf

You have to put everything after "Then" in a new line:

$var = Regread($Value)
If @Error Then
    Msgbox(0,"test", "Does Not Exist")
Else
    Msgbox(0,"test", "Does Exist")
EndIf

I would also not only test for negative @error values. Everything that is not 0 is an error (positive and negative).

See the help file for RegRead:

Failure:

Returns "" and sets the @error flag:

1 if unable to open requested key

2 if unable to open requested main key

3 if unable to remote connect to the registry

-1 if unable to open requested value

-2 if value type not supported

Thanks guys, that worked. In this instance, I am only checking to see if it exsists, and it it does not (which should only be a -1) then I will write one.

Am I correct in my logic?

Yep you're spot on with your logic

Thanks
