Is it possible to set default parameters?

Recommended Posts

Hey all!

Just a short question to the experienced coders: is it possible to define default parameters, so thta if I try to call a function with less than the normal amount of parameters, it reverts to the default value?

yeah

Optional parameters are defined by assigning a default value to them, which could be a macro. They are always the last in the definition. If a parameter is given a default value, then all parameters after that one must also be given default values

http://www.autoitscript.com/autoit3/docs/keywords/Func.htm

like so:

Func _Func1($P1, $P2 = 0, $P3 = "abc")
endfunc
oÝ÷ Øźw5¶©j¶¦z׫³Mú?f§wMú?v«y×jémyÛhѩݪê-*ºkzÊ^rدz¢'ò¢çQnÍpØij¶¦z׫²Ë«ºÚ"µÍÑ[ÌJJoÝ÷ ÛMú?f§wMú?v«y«­¢f­Æ¥+¶Ú4jwjºZmÊ®¢Ö(¹Æ§¢÷«×yö®ÛÚç¬o&v)ඩj¶¦z׫²)íçîËb¢w[.r¬jëh×6_Func1(1, 1, "def")

now $P2 and $P3 have been overridden to 1 and "def" respectively.

Hi all,

Related question:

I've got a function defined like this:

func saveOptions($showAlert=0)
    msgbox(0, "showalert", $showAlert); Used to debug only
       ; More code here
endfunc

If I call the function with saveOptions(0) or saveOptions(1), it works OK. The msgbox appears OK.

If I call it with saveOptions() , which should default to '0', I get an undefined variable error.

What gives?

Works fine here.

Common sense plays a role in the basics of understanding AutoIt... If you're lacking in that, do us all a favor, and step away from the computer.

Same as SmOke_N, it works for me:

saveOptions()

Func saveOptions($showAlert = 0)
    MsgBox(0, "showalert", $showAlert); Used to debug only
    ; More code here
EndFunc   ;==>saveOptions

You must have a typo...

That line fails in the way I've described.

Ah, hold on. I tested it using ONLY this code in a new file:

And you're right, it works.

The way the function was being called in my original app was via:

Uncomment the MsgBox() in _Quit() and you get the error back for trying to use the parameter.
