 Posted: Wed Jan 13, 2010 9:54 pm Post subject: How to make a "composite" variable? |
 |
|
Hello,
Let's say my array is "StateCity"
I want to retrieve StateCity1, but the "1" is actually a variable that is equal to 1
If A = 1, how do I write the variable so AHK will understand this?
I've tried StateCityA, StateCity%A%, %StateCity%%A%, none of which seem to work. Is this a "dynamic variable"? Thanks for the help!! |

| Code: | A = 1
StateCity1 = one
StateCity2 = two
StateCity3 = three
var := StateCity%A% ; Expression (:=)
Msgbox % var
; or
A++ ; A = 2
var = % StateCity%A% ; Traditional (=)
Msgbox % var
var := "StateCity" A + 1
var := %var%
Msgbox % var
; etc |

Hmm, ok. Is there some reason why the % Var1%Var2% syntax works in some cases but not others?
ie,
| Code: |
;if you make a WinGet, WinID, List array...
MsgBox % WinID%A% ;this works great
WinGet, program, ProcessName, ahk_id % WinID%A% ;but this is a syntax error ("the following variable name contains an illegal character: WinID") |
Why? |

Putting " % " at the beginning of a command's parameter forces AHK to see the rest of that parameter as an expression. For example: | Code: | ; example: using a dynamic variable which holds a window's unique ID
WinGet, program, ProcessName, % "ahk_id " . WinID%A_Index%
; notice the literal string "ahk_id " has a space on the left.
; this expression resolves to ahk_id 0x12345678
; example: using dynamic variables in a gui command
Gui, Add, Button, % "x" ( GuiWidth // 2 - ButtonWidth // 2 ) " y" ( GuiHeight // 2 - ButtonHeight // 2 ) " w" ButtonWidth " h" ButtonHeight " gSomeLabel", Button Text
; This would add a button smack-dab in the middle of the gui, provided the gui was actually
; as wide and tall as the variables imply
; example: using dynamic variables in the click command. 'Click' is a bit strange in that it only has 1 parameter
Click, % (A_ScreenWidth // 2) " " (A_ScreenHeight // 2) " Left 2"
; double-clicks the middle of the screen, assuming 'coordmode, mouse ,screen' is in effect |

So does this work?
| Code: | | WinGet, program, ProcessName, % "ahk_id" WinID%A% |
Found this in | Help --> MsgBox wrote: | | Code: | ; By preceding any parameter with "% ", it becomes an expression. In the following example,
; math is performed, an array element is accessed, and a function is called. All of these
; items are concatenated via the "." operator to form a single string displayed by MsgBox:
MsgBox % "New width for object #" . A_Index . " is: " . RestrictWidth(ObjectWidth%A_Index% * ScalingFactor) |

With an extra space between ahk_id and variable probably so 
| Code: | | WinGet, program, ProcessName, % "ahk_id " WinID%A% |

Can anybody tell me why this doesnt work? Ive tried so many different combinations I have no idea. Also tried going from "clipboard" to a temporary variable, then into the array. If I add any spaces before/after any of the %'s I get errors when opening the script.
| Code: |
F1::
InputBox,times,How many?
x = 0
Loop, %times%
{
SetTitleMatchMode, 2
WinActivate, Excel
Send, ^c
Sleep, 200
%Sim%x% := clipboard
Sleep, 200
Send, {RIGHT}
Sleep, 200
Send, ^c
Sleep, 200
%Imei%x% := clipboard
Sleep, 200
Send, {DOWN}{LEFT}
Sleep, 200
x++
}
x = 0
Loop, %times%
{
MsgBox, %Sim% x% - %Imei% x%
x++
}
Return
|
Thanks in advance |

You have to be more observant about how you create and call dynamic variables:
| Code: | F1::
x = 0
InputBox,times,How many?
Loop, %times%
{
SetTitleMatchMode, 2
WinActivate, Excel
Send, ^c
Sleep, 200
Sim%x% := clipboard
Sleep, 200
Send, {RIGHT}
Sleep, 200
Send, ^c
Sleep, 200
Imei%x% := clipboard
Sleep, 200
Send, {DOWN}{LEFT}
Sleep, 200
x++
}
x = 0
Loop, %times%
{
MsgBox, % Sim%x% - Imei%x% ; you must force expression mode to perform a math operation
x++
}
Return |

Thanks for your response but it still doesnt work and Im not quite sure why.
All I get is a msgbox saying "Sim1 - Imei1" , "Sim2 - Imei2", etc. |

...check your percents!...(it works for me)...
| Code: | x=0
Loop, 19 {
Sim%x% := 19
Imei%x% := 38
x++
}
x=0
Loop, 19 {
msgbox, Sim%x% - Imei%x%
;// ^--- % missing = msgbox = Sim0 - Imei0
msgbox, % Sim%x% - Imei%x%
;// ^--- % present = msgbox = -19
x++
} |

| To be fair and honest, AHK's syntax is horrible. |

| Well that's my opinion, and the opinion of a person who has experience programming in a dozen languages. I could go on and give all the reasons, but whatever - I just hope the syntax is tightened in up a future edition (which will also make it easier to learn, and hence this thread would never exist). |

| I know only AHK, and it sure is ugly when we need to write everything on a single line, however, it becomes extremely simple when we written intermediate lines to avoid more % |

| The only good part of AHK's syntax is the key binding syntax... which is just as well, given "Hotkey" is in its name! |
