New expression format doesn't seem to work

[radadar]

I've been away from AHK for a while and I'm trying to get away from the depreciated format but I'm constantly having problems with the new format.

One example:

If I use the new format of

Code: Select all

if WinExist("ahk_class Notepad")

The script moves along as if notepad was open whether or not it is.

If I use the depreciated

Code: Select all

IfWinExit, ahk_class Notepad

Everything works fine.

Any ideas what I'm doing wrong? I'm on AHK version 1.1.30.00

Thanks.

That doesn't seem likely. The expression you posted will always work. The depreciated version you posted will never work.

Make sure there's no space between WinExist and the open parenthesis. That would make it concatenation, not a function call.

Also make sure you put braces around the block of code the if-statement is intended to affect, if it's more than one line.

How about
#if WinActive("ahk_class Notepad")
?

How about
#if WinActive("ahk_class Notepad")

Yea,

There is a big difference between:
if and #if

and between
ifWinExist and #ifWinExist

Sorry I'm confused doesn't the hatch make it a hot key/string. I don't want a hotkey.

no. # indicates the start of a directive

When you use the # it is then a script directive that effects all hotkeys below it in the script.

But as to your probem, these two hotkeys act the same for me.

Code: Select all

F12::
	if WinExist("ahk_class Notepad")
		MsgBox NOTEPAD EXIST
	else
		MsgBox NOPE
return

F11::
	IfWinExist, ahk_class Notepad
		MsgBox NOTEPAD EXIST
	else
		MsgBox NOPE
return

Now if you were to do this:

Code: Select all

#if WinExist("ahk_exe Excel.exe")

F12::
	if WinExist("ahk_class Notepad")
		MsgBox NOTEPAD EXIST
	else
		MsgBox NOPE
return

F11::
	IfWinExist, ahk_class Notepad
		MsgBox NOTEPAD EXIST
	else
		MsgBox NOPE
return

Neither hotkey would do anything unless an Excel window exist.
