>Just now I got this error message. I know why it happened, it's because I choose lot's of items in multilist, which affect on Init method one of my other controls. I think, it's VFP limitation 255 char on the macro string. So, my questions are:
2) How can I resolve this situation? Do I need to calculate length of my macro string, finding space, etc. Would be a real PITA :(

Could you limit the selections in the multilist? (if normal use says 3-4 choices is adequate, 15 kills your code, limit the picklist to 10 at a time)

Assuming your macro is something like: Select ... Where ¯ostring,
Maybe you could do: Select ... Where value1 In Select value2 where value3=.T.
(value1=keyvalue, value2=picked value, value3=value2 was picked or not)

Or maybe I/we don't have enough info on what you're trying to do?
