Can I use WM_COMMAND to handle EN_CHANGE message but not BN_CLICKED? As long WM_COMMAND process the message BN_CLICKED I am not able to catch the button click in loop using GUIGetMsg().

#include <WindowsConstants.au3>
#include <EditConstants.au3>
#include <ButtonConstants.au3>
#include <WinAPI.au3>

$hMain = GUICreate("Test",400,400)
$hButton = GUICtrlCreateButton("Click Me",100,100,100,30)
$hInput = GUICtrlCreateInput("",100,200,100,30)
GUIRegisterMsg($WM_COMMAND,'WM_COMMAND')
GUISetState(@SW_SHOW,$hMain)

While True
    Switch GUIGetMsg()
        Case $hButton
            MsgBox(0,"Message","You just clicked me.")
        Case -3 ; GUI_EVENT_CLOSE
            Exit
    EndSwitch
WEnd

Func WM_COMMAND($hWnd, $iMsg, $wParam, $lParam)
    Switch _WinAPI_HiWord($wParam)
        Case $EN_CHANGE
            TrayTip("Read",GUICtrlRead(_WinAPI_LoWord($wParam)),1)
            Return 0
    EndSwitch
    Return _WinAPI_DefWindowProc($hWnd, $iMsg, $wParam, $lParam)
EndFunc

EDIT: I got this working in this way but I'm looking for something more elegant

#include <WindowsConstants.au3>
#include <EditConstants.au3>
#include <ButtonConstants.au3>
#include <WinAPI.au3>

$hMain = GUICreate("Test",400,400)
$hButton = GUICtrlCreateButton("Click Me",100,100,100,30)
$hInput = GUICtrlCreateInput("",100,200,100,30)
$hDummy = GUICtrlCreateDummy()
GUIRegisterMsg($WM_COMMAND,'WM_COMMAND')
GUISetState(@SW_SHOW,$hMain)

While True
    Switch GUIGetMsg()
        Case $hDummy
            Switch GUICtrlRead($hDummy)
                Case $hButton
                    MsgBox(0,"Message","You just clicked me.")
            EndSwitch
        Case -3 ; GUI_EVENT_CLOSE
            Exit
    EndSwitch
WEnd

Func WM_COMMAND($hWnd, $iMsg, $wParam, $lParam)
    Switch _WinAPI_HiWord($wParam)
        Case $EN_CHANGE
            TrayTip("Read",GUICtrlRead(_WinAPI_LoWord($wParam)),1)
            Return 0
        Case $BN_CLICKED
            GUICtrlSendToDummy($hDummy,_WinAPI_LoWord($wParam))
    EndSwitch
    Return _WinAPI_DefWindowProc($hWnd, $iMsg, $wParam, $lParam)
EndFunc

That's how I would do it, as stated in the reply PM I sent to you.

Could you not do this.

#include <GUIConstantsEx.au3>

Func WM_COMMAND($hWnd, $iMsg, $wParam, $lParam)
    Switch _WinAPI_HiWord($wParam)
        Case $EN_CHANGE
            TrayTip("Read",GUICtrlRead(_WinAPI_LoWord($wParam)),1)
            Return 0
        Case $BN_CLICKED
            Return $GUI_RUNDEFMSG ;If you want AutoIt to run its internal handler for a message, return the variable $GUI_RUNDEFMSG
    EndSwitch
    Return _WinAPI_DefWindowProc($hWnd, $iMsg, $wParam, $lParam)
EndFunc

Hmm...does that work? If it does then I have learnt something new today.

UDF List:

Do a switch on the control id first?

 

#include <GuiConstantsEx.au3>
#include <WindowsConstants.au3>
#include <EditConstants.au3>
#include <ButtonConstants.au3>
#include <WinAPI.au3>

$hMain = GUICreate("Test", 400, 400)
$cButton = GUICtrlCreateButton("Click Me", 100, 100, 100, 30)
$cInput = GUICtrlCreateInput("", 100, 200, 100, 30)
GUIRegisterMsg($WM_COMMAND, 'WM_COMMAND')
GUISetState(@SW_SHOW, $hMain)

While True
Switch GUIGetMsg()
Case $cButton
MsgBox(0, "Message", "You just clicked me.")
Case -3 ; GUI_EVENT_CLOSE
Exit
EndSwitch
WEnd

Func WM_COMMAND($hWnd, $iMsg, $wParam, $lParam)
Switch _WinAPI_LoWord($wParam) ; iIDFrom
Case $cInput
Switch _WinAPI_HiWord($wParam) ; iCode
Case $EN_CHANGE
TrayTip("Read", GUICtrlRead(_WinAPI_LoWord($wParam)), 1)
;Return 0
EndSwitch
EndSwitch
Return $GUI_RUNDEFMSG
EndFunc ;==>WM_COMMAND

Edit:

Also you used

$hButton = GUICtrlCreateButton("Click Me", 100, 100, 100, 30)

from the "h" I would think the variable contains a handle. I recommend to use something more like this:

$cButton = GUICtrlCreateButton("Click Me", 100, 100, 100, 30)

$hButton = GUICtrlGetHandle($cButton)

I was wondering why all this short examples work so good and when I work on my project nothing works as I expect. The answer is simple and I have to apologize JohnOne and I should listen guiness >long time ago. I don't know why but I knew that $GUI_RUNDEFMSG='' and of course I used magic numbers and magic texts so it's obviously that script not behaved as I expected. Thanks guys!

PS: Now I like the old comment of guinness.  :graduated:
