Last created control = ? + Call with variable pars

Recommended Posts

martin

Q1

When a control is created you can refer to the last control by using -1 instead of the control id.

How do I know in my script what the last created control ID was? I know I can use enumchildwindows but I wondered if there was something like a variable similar to $Gui_CtrlId that I could use but I can't find.

Q2

I want to call a function but I don't know at design time the function name or how many parameters. The functions will already have been written and cannot be modified.

I know I can use Call("func1",$par1,$Par2), but if the function to be called has 3 parameters how can I call the function programmatically with the correct number of parameters.

To put it another way, how do I improve on this?

Function($callfunc,$NumParams,$Par1,$par2='',$par3='',$par4='')

switch $NumParams
  Case 1
   Call($callfunc,$par1)
  Case 2
   Call($callfunc,$par1,$par2)
  Case 3
   .
   .
   .
 endswitch

endfunc

  Case 3
   .
   .
   .
 endswitch

endfunc
The way to do it is

$exec = "Call($callfunc"
    for $n = 1 to $NumParams
        $exec &= ", $Param" & $n
    Next
    $exec &= ")"
    Execute($exec)

Now please stop bothering me so I can get on with some work.

How do I know in my script what the last created control ID was?

#include <GuiConstantsEx.au3>

$GUI = GUICreate("Get Last CtrlID - Example", 300, 200)

GUICtrlCreateButton("Button", 20, 40, 60, 20)

GUICtrlCreateLabel("Some Label", 20, 80)
GUICtrlCreateCheckbox("Some CheckBox", 20, 120)

GUISetState(@SW_SHOW, $GUI)

$iLastCtrlID = _GUIGetLastCtrlID()

MsgBox(64, "Last CtrlID", StringFormat("Last CtrlID Is: %i\nData from CtrlID: %s", $iLastCtrlID, GUICtrlRead($iLastCtrlID, 1)))

While 1
    $nMsg = GUIGetMsg()
    Switch $nMsg
        Case $GUI_EVENT_CLOSE
            Exit
    EndSwitch
WEnd

Func _GUIGetLastCtrlID()
    Local $aRet = DllCall("user32.dll", "int", "GetDlgCtrlID", "hwnd", GUICtrlGetHandle(-1))
    
    Return $aRet[0]
EndFunc

:) Thanks MsCreatoR, that's just what I need. Excellent. That makes my script very much better; I should have known about that but I didn't.
