[Solved]Can't use expression in SendMessage's arg Msg Topic is solved

[RobertL]

[Update by Lexikos: Legacy syntax was removed in v2.0-a079.]

(At least,) Command SendMessage's first arg Msg doesn't support expression in AHK V2.
So

Code: Select all

x:=12,
SendMessage x,..        ;don't work
SendMessage % x,..    ;could work

This is intentional, and for consistency purposes. Please use force-expression mode or actual expression syntax to call SendMessage.

Command args are never expressions by default, except with control flow statements such as Return. The % (percent followed by space) prefix can still be used to force an expression.

Oh, sorry, I forget it. I just only searched for "SendMessage" in "Changes from v1.1 to v2.0".
Or Command called as functions——Command().
