I need to call an AutoHotkey script that will return a value.
For example, something like this:
return_val = Shell("AutoHotKey.exe script.ahk")
My script looks like this:
IfExists, filename
return 1
Else
return 0
I get an error telling me I can't have a value in the terminating return statement. I have also tried using the Exit statement instead of return.
How can I return a value from an AutoHotkey script?
To return an exit code you'll want to call ExitApp along with your desired code. Use IfExist to determine if the file exists. This means the script that you call should look like this:
IfExist, c:\test.txt
ExitApp, 1
Else
ExitApp 0
When calling the script you should use RunWait and pass it the UseErrorLevel
parameter. This will set the variable ErrorLevel
to the exit code of the called process if it launches correctly or the text ERROR
if the process cannot be started.
RunWait, C:\Program Files (x86)\AutoHotkey\AutoHotkey.exe "C:\script.ahk",, UseErrorLevel
MsgBox %ErrorLevel%
In this example the message box will display '1' if the file exists or '0' if it doesn't.
