Why my StringReplace don't work?

问题

I want to replace the comma character into another based on order Chr

^Numpad4::
StringReplace, clipboard, clipboard,%Chr(44),%Chr(45), All
Return

But why I cannot use it?Are any wrong in my code?

回答1:

In a command's parameters you have to use expression syntax:

^Numpad4::
StringReplace, clipboard, clipboard, % Chr(44), % Chr(45), All
; MsgBox, %clipboard%
Return

Without the percent sign and the space, Chr(44) is a literal string.
