problem with "if FileExist"

[raf58]

hello everybody

I have a small but very ennoying issue, just starting to play with AutoHotkey
already spent severals hours to find out why

in the tiny test code below, the 1st msgbox says "YES" but the 2nd (with %var%) says "NOT"

why??
what is the solution to pass as parameter the filename ?

thanks for any input !

Code: Select all

#y::
var=mydoc.txt
if FileExist("c:\mydoc.txt")
MsgBox, YES_exists 
else MsgBox, ...NOT_exists

if FileExist("c:\%var%")
MsgBox, YES_exists 
else MsgBox, ...NOT_exists

return

In expression mode (which includes the parameter section of a function call), literal strings need to be quoted, and variables should have no %s around them. You can concatenate these different parts:

Code: Select all

if FileExist("c:\" var)
