Stuck with Select / Switch

Recommended Posts



I'm totally struck with the declaration of variables, and / or with Select and Switch.

I'm trying to set up a macro system for my computer, for various hotkeys and for different scopes, i.e.

depending on the program that is running, the same hotkey is to have a different effect, i.e. to trigger

a different macro. Thus, I did this:

global $scope ; is to be numeric, I first called it just $s, but 1 character or more, problems stay

global $title ; this is the name of the current program in use

Opt("WinTitleMatchMode", 2) ; set to "substring" (default is 1 = "start")

; this is necessary since the titles contain program names AND file names, sometimes at the beginning

Opt("MustDeclareVars", 1) ; yes (default is 0 = no) ; yes or no doesn't make any difference for my problem

; here I deleted most of my script in order to make it more readable:

hotkeyset ("{F3}", "A" )

hotkeyset ("{F4}", "B" )

hotkeyset ("{F5}", "C" )

While 1

Sleep (100)


Func A()

GetScope() ; runs my function GetScope() below

; gets never back to function A() though:

Switch $scope

Case 1


Case 2


Case 3


MsgBox(0, "And again, scope is:", $scope) ; never...

Case 4



; of course, I tried with Select, then Case $scope = 1, $scope = 2, etc.

; I also tried with "==" instead of "=", to no avail


Func B()


; same missing of results


Func C()

; etc. etc.


Func GetScope()

$title = WinGetTitle("[active]") ; this indeed gets the correct title into that variable

Switch $title

Case "iGrafx Flowcharter 2000"

$scope = 1

Case "ActionOutline"

$scope = 2

Case "Ultra Recall Professional"

$scope = 3

Case "Windows Internet Explorer"

$scope = 4 ; I tried all these with and without indentation, to no avail


MsgBox(0, "Full title of active window is:", $title) ; it's correctly presented

MsgBox(0, "Scope is:", $scope) ; it's always void or 0 (zero) if I had initialized it that way


; Thus, NEVER EVER the statement line(s) after the case lines are executed, the values (1 to 4) are

; never assigned to the (numerical) variable.

What do I wrong, please? (Of course, I tried the help and the forum, for Select, Switch, declaration of variables, scope of variables, variable assignment, call for functions within other functions, etc. etc.)

You are doing an exact match in the GetScope() Func and likely the Window title is different.

E.g.: Case "Windows Internet Explorer" The content in $title is more than the Case string you test against.

Your problem is that you're not trying to compare the Window title with the Case statements. You're comparing the contents of $title variable to part of what you're expecting the window title to be.

Try this instead:

        Case StringInStr($title, "iGrafx Flowcharter 2000")
            $scope = 1
        Case StringInStr($title, "ActionOutline")
            $scope = 2
        Case StringInStr($title, "Ultra Recall Professional")
            $scope = 3
        Case StringInStr($title, "Windows Internet Explorer")
            $scope = 4 ; I tried all these with and without indentation, to no avail

If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

Jos and BrewManNH, you're both totally right, I am deeply indebted to you. This is a tremendous site with tremendous help, that's why I've chosen AI over AHK. I'm really glad such a fine community exists. (I've finally come to experiment with AI, so I'm a total beginner, and thus I only searched my probable error in the probable misunderstanding of the language, instead of also checking the logic of my thinking, that's why I'd been stuck. Many, many thanks again!)
