ClassNameNN Returned by ControlGetFocus()

[BruceCopperField]

A newbie question. ControlGetFocus() returns a ClassNameNN. How do we use it to uniquely identify which control is having the focus? It seems that if i have say 4 input control, their ClassNameNN are all 'Edit0'?

I'd like to see "the right way" to do this as well, but in the mean time here's an idea...

I've gotten around this by getting the ClassNameNN at the time I build the GUI...

create the controls, give each one focus & get its ID into a variable, continue building the GUI.

expandcollapse popup

#include <guiconstants.au3>
opt("GUIOnEventMode",1)
guicreate("TEST")
$input1 = GUICtrlCreateInput("",20,20,75,20)
$input2 = GUICtrlCreateInput("",20,50,75,20)
$input3 = GUICtrlCreateInput("",20,80,75,20)
$input4 = GUICtrlCreateInput("",20,110,75,20)
$button1 = GUICtrlCreateButton("focus input1",100,20,80,20)
$button2 = GUICtrlCreateButton("focus input2",100,50,80,20)
$button3 = GUICtrlCreateButton("focus input3",100,80,80,20)
$button4 = GUICtrlCreateButton("focus input4",100,110,80,20)

ControlFocus("TEST","",$input1);give focus to $input1
$id1 = ControlGetFocus("TEST");get $input1's ClassNameNN into a variable
ControlFocus("TEST","",$input2);rinse & repeat
$id2 = ControlGetFocus("TEST")
ControlFocus("TEST","",$input3)
$id3 = ControlGetFocus("TEST")
ControlFocus("TEST","",$input4)
$id4 = ControlGetFocus("TEST")

GUICtrlSetOnEvent($button1,"input1")
GUICtrlSetOnEvent($button2,"input2")
GUICtrlSetOnEvent($button3,"input3")
GUICtrlSetOnEvent($button4,"input4")
ControlFocus("TEST","",$input1);
guisetstate()
GUISetOnEvent($GUI_EVENT_CLOSE,"close")

while 1
    sleep(1000)
WEnd
func input1()
    ControlFocus("TEST","",$input1)
EndFunc
func input2()
    ControlFocus("TEST","",$input2)
EndFunc
func input3()
    ControlFocus("TEST","",$input3)
EndFunc
func input4()
    ControlFocus("TEST","",$input4)
EndFunc
func close()
    Exit
EndFunc

if i have say 4 input control, their ClassNameNN are all 'Edit0'

No, if you have four INSTANCES of CLASS:Edit controls, their ClassNameNN's returned will be Edit1, Edit2, Edit3, or Edit4.

There is a dll cal you can make to get the ControlID number if you must:

$sClassNameNN = ControlGetFocus("", "")
$hCtrlFocus = ControlGetHandle("", "", $sClassNameNN)
$ctrlFocus = ControlGetID($hCtrlFocus)
MsgBox(64, "Results", "The control with current focus was:" & @CRLF & _
        @TAB & "ClassNameNN = " & $sClassNameNN & @CRLF & _
        @TAB & "HWND = " & $hCtrlFocus & @CRLF & _
        @TAB & "ID = " & $ctrlFocus)

Func ControlGetID($hWnd)
    $avRET = DllCall("User32.dll", "int", "GetDlgCtrlID", "hwnd", $hWnd)
    If @error or $avRET[0] = 0 then Return SetError(1, 0, 0)
    Return $avRET[0]
EndFunc

But if you already have the ClassNameNN, and you can get the handle from that with ControlGetHandle(), you usually don't need the ControlID.
