Hi Jonathan,
This is what Chip means:
Function ReturnControl( Obj, MySearchItem)
'Return A Control.
Set ReturnControl = Nothing
FOR EACH oChild IN Obj.Children
IF oChild.Name = MySearchItem THEN
Set ReturnControl = oChild
EXIT Function
End If
END FOR
End Function

Hi Jonathin,
First, you should not use the variable you are using to loop through your
collection, outside of the "for each" loop. It's not defined to have any
value. This is why you are sometimes getting an error in the line which
tries to use oChild.
I'd suggest before the "for each" loop, that you set the function's return
value to be "nothing"; so if you don't find it, this is what the function
will return.
Then, inside of the "if" inside the "for each", when you find the control,
set the function's return value to be what you found, and then have a "exit
function" command to stop searching.
There are other ways of doing this: set a variable to "nothing" before the
"for each" loop, and then set this variable to the found control if/when you
find it, and then have a "exit for" as you do.
After the loop, then set the function to return this variable.
It comes out to be about the same as my first suggestion, but maybe you find
it a little clearer.
Hth,
Chip

Subject: When a search fails how to handle.
Good day,
I have made progress in creating a script that searches for a given control.
FOR EACH oChild IN Obj.Children
IF oChild.Name = MySearchItem THEN
EXIT FOR
END FOR
' Nex line errors when search failed.
IF oChild
IS NOTHING THEN
ReturnValue = NOTHING
ELSE
ReturnValue = oChild
END IF
What should I be using in the second IF clause?
Thanks,
Jonathan
