set function to control


Recommended Posts

i have a function

Func test($var)
MsgBox(0, "", $var)
EndFunc

i want to make 2 buttons:

1 that calls to test("a") and the other that calls to test("b").

after i made the 2 buttons, how do i make them call to the function with the variables?

the second is if i can let the user select more then 1 option in GUICtrlCreateList?

like this ? (from helpfile and me)

GUICreate("My GUI Button") ; will create a dialog box that when displayed is centered

Opt("GUICoordMode",2)
$a= GUICtrlCreateButton ("A",  10, 30, 50)
$b= GUICtrlCreateButton ( "B",  0, -1)

GUISetState ()    ; will display an  dialog box with 2 button

; Run the GUI until the dialog is closed
While 1
    $msg = GUIGetMsg()
    
    If $msg = $GUI_EVENT_CLOSE Then ExitLoop
    If $msg= $a then MsgBox (0, "A", "A")
    If $msg= $b then MsgBox (0, "B", "B")
Wend

it's written in the topic...

and i have another problem:

what's wrong with this?

$par_a = ""
$par = "a"
$open = "text"
Eval("par_" & $par) = $open

i get the error:

Illegal text at the end of statement (one statement per line)

The only thing Eval does is return the value of the variable.

You can't assign a value to a variable using Eval.

You will need to use Assign for that.

$par_a = ""
$par = "a"
$open = "text"
Assign("par_" & $par, $open)

If you get an error message, check the help file for more info.

If that's not enough, ask here.

You can also use the Event mode rather than GuiGetMsg which is sometimes easier to understand:

Look up GuiCtrlSetOnEvent which gives this example:

#include <GUIConstants.au3>

Opt("GUICoordMode",2)
Opt("GuiOnEventMode", 1)

$parent1 = GuiCreate("Parent1")

$ok1 = GUICtrlCreateButton ("OK",  10, 30, 50)
GUICtrlSetOnEvent(-1, "OKPressed")

$cancel1 = GUICtrlCreateButton ( "Cancel",  0, -1)
GUICtrlSetOnEvent(-1, "CancelPressed")

GuiSetState(@SW_SHOW)

; Just idle around
While 1
    Sleep(10)
Wend


; END


Func OKPressed()
    MsgBox(0, "OK Pressed", "ID=" & @GUI_CTRLID & " WinHandle=" & @GUI_WINHANDLE & " CtrlHandle=" & @GUI_CTRLHANDLE)
EndFunc


Func CancelPressed()
    MsgBox(0, "Cancel Pressed", "ID=" & @GUI_CTRLID & " WinHandle=" & @GUI_WINHANDLE & " CtrlHandle=" & @GUI_CTRLHANDLE)
EndFunc

You can only specify a function to call (no parameters) but for your case you could easily do something like this,

Func TestA()
  Test("a")
EndFunc

Func TestB()
  Test("b")
EndFunc

Func Test($var)
  MsgBox(0, "", $var)
EndFunc
