[HELP] Problem with control Layering and WM_COMMAND

4 posts in this topic

Hello,

How come in this example, when I click on label 2, I get the notification for Label 1?

I have 2 controls overlapping, and I cannot disable them.

#include <WindowsConstants.au3>
#include <GUIConstantsEx.au3>

Global $GUI, $LABEL1, $LABEL2
$GUI = GUICreate("Test", 800, 600)
$LABEL1 = GUICtrlCreateLabel("Label 1", 40, 40, 700, 520)
GUICtrlSetBkColor(-1, 0xFF0000)
$LABEL2 = GUICtrlCreateLabel("Label 2", 100, 100, 600, 400)
GUICtrlSetBkColor(-1, 0x00FF00)

GUISetState()
GUIRegisterMsg($WM_COMMAND, "WM_COMMAND")

While 1
    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE
            Exit
    EndSwitch
    Sleep(50)
WEnd

Func WM_COMMAND($hWnd, $iMsg, $iwParam, $ilParam)
    #forceref $hWnd, $iMsg
    Local $hWndFrom, $iIDFrom, $iCode
    $hWndFrom = $ilParam
    $iIDFrom = BitAND($iwParam, 0xFFFF) ; Low Word
    $iCode = BitShift($iwParam, 16) ; Hi Word
    Switch $hWndFrom
        Case GUICtrlGetHandle($LABEL1)
            MsgBox(0, "Click received", "Label 1 was clicked")
        Case GUICtrlGetHandle($LABEL2)
            MsgBox(0, "Click received", "Label 2 was clicked")
    EndSwitch
    Return $GUI_RUNDEFMSG
EndFunc   ;==>WM_COMMAND

Thanks in advance for your help.

Here a workaround:

#include <WindowsConstants.au3>
#include <GUIConstantsEx.au3>

Global $GUI, $LABEL1, $LABEL2
$GUI = GUICreate("Test", 800, 600)
$LABEL1 = GUICtrlCreateLabel("Label 1", 40, 40, 700, 520)
GUICtrlSetBkColor(-1, 0xFF0000)
$LABEL2 = GUICtrlCreateLabel("Label 2", 100, 100, 600, 400)
GUICtrlSetBkColor(-1, 0x00FF00)

GUISetState()

While 1
    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE
            GUIDelete()
            Exit
        Case $GUI_EVENT_PRIMARYDOWN
            $aM = GUIGetCursorInfo($GUI)
            Switch $aM[4]
                Case $LABEL1
                    MsgBox(0, "Click received", "Label 1 was clicked")
                Case $LABEL2
                    MsgBox(0, "Click received", "Label 2 was clicked")
            EndSwitch
    EndSwitch
;~     Sleep(50)
WEnd

Here a workaround:

Thanks UEZ. This workaround works. Still I find the behavior of WM_COMMAND weird... I don't understand why my example doesn't work.

I'll use your trick in the meantime.

Whici one you want to disable it? Or you want both to be clickable?

I don't want to disable them, I just want to receive the notification when I click on the labels.

Actually the reason I am asking this, is because I need it in my I want to receive the notification when I click on the event, but I always receive the notification of the day, not the event...

      The WM_COMMAND never fires from the context/popup menu selection while there is a treeview using  _GuiCtrlTreeview_Create
      If you comment out _GuiCtrlTreeview_Create line you will then see the right click selection works as expected and the debug is written to the console on selection.

      Any ideas why this combination won't work together?

      Hey guys, MattDiesel over Stackoverflow mentioned this beautiful piece of code 
      #include <WindowsConstants.au3> #include <WinAPI.au3> Local $IDM_FONT = 33 Local $hWindow = WinGetHandle("Untitled - Notepad") _WinAPI_PostMessage($hWindow, $WM_COMMAND, $IDM_FONT, 0) Local $hFontWin = WinWait("Font") $select = ControlCommand($hFontWin, "", "ComboBox1", "GetCurrentSelection", "") WinClose($hFontWin) MsgBox(0,"", $select) I realized that _WinAPI_PostMessage can trigger menu click event, even if Notepad is minimized.
      How do we know what is the decimal value of *any menu item or sub-menu item*? How we know "Format > Font" menu-item is 33 as wParam to _WinAPI_PostMessage()? Have a look at snapshot.
      Regards.

      Hi guys!
      First of all, I want to apologize with @Melba23, @JLogan3o13, and @Jos ( I don't know why the tag sometimes works and sometimes doesn't ), for my bad attitude I have had with
      them. I want to explain why I was so angry, but that's not an excuse to my bad attitude...
      I have health problem, and lastly, I am ever more angry because I'm fighting with these problems for 5 years and I feel worse than 5 years ago, even If I had a lot of investigations about with a lot of Doctors, and there's no cure for my pathology. I don't want to touch anyone with my "story", but I wanted to explain why, sometimes, you can feel my anger in my words.
      I promise I'll try to be as polite as my mom taught me, and to explain all I'd like to develop, posting all you need ( sample codes... ).

      Now, let's talk about my project.
      Let's start from 0! 
      I'd like to implement a database with AutoIt, for the warehouse management.
      First of all, I'd like to set some "goals" which I want to respect, developing my application:
      Efficiency: I'd like to develop an application that is fast as possible; Easy to make changes: I'd like to develop an application that is easy to modify, so, without too much complicated arguments; Noob-proof: As a noob as I am, my AutoIt knowledge starts from June 2016, so, I'm not a blade in this programming language. I studied C++, C, JavaScript, CSS, HTML and PHP, but, all of these programming language has a different approach comparing with AutoIt. I could be wrong in what I just estabilished! I want to tell you, again, that I'm here to listen to your suggestions, so, everything you say, it's something that I could learn, and I want to learn AutoIt, so, don't be scared to share your opinions, or your knowledge! I'm here to learn "How to AutoIt!"  Ok, so, after having set some goals I'd like to hit, I want to ask you some information:
      What's the best way to develop a database with AutoIt? With a .txt file? With an Excel workbook? 
      I was working on Excel workbook, but, I don't know, I could always be wrong in terms of efficiency and "easy to make changes"; I have to create a GUI, in order to let the user do things ( I think it was quite obvious ), so, I have been always used GUI functions like GUICreate and so on; anything about _GDI_Plus or something else. Most, I used _GUI* functions. What's the best way to manage different GUIs? OnEvent Mode or Message Loop "mode"? Now, I'd like to make a list of what I'd like my application would do:
      Reading stocks: I manage mainly 2 manufacturers, so, If I will work with an Excel workbook, I'd prefer to divide first manufacturer with the second; Add product: Simply, If a product does exist, the application prompt to the user an input box, with a sort of summary ( Product name, quantity ) of the product he's adding; ELSE, if the product does not exist, an "Add New Product" GUI should appers; Withdraw product: As a warehouse, I need to add and to withdraw product... This "function" should performs the simply task of reserach the product based on his ID and, prompt an InputBox to the user, with a little summary of the product he's withdrawing and, the quantity of the product after the withdraw; Search product: I'd like to develop a "product reserach", based on the ID of the product(s), or based on the Description of the product(s)... It'd be very nice!  Create DDT: Create a DDT with a pre-formatted Excel sheet. Just insert some information, and then all the products that have been withdrawn from the database ( maximum 14 per DDT ); I have already done some of work I described here, and you can find all files you need attached to this post. 
      I don't want you to do this. Just, don't post your code that I have been looking for, but let me try, with your help, to get an appropriate and efficient solution to what I'm asking.
      The last, but not the less important, the recognition I can give to you is publish your name ( or alias ) on the "developer section", more than a donation for everyone who has take part to this project.

      Please, if you want to know further information ( I think I've been exhaustive enough ), write here or on a PM. 

      Another time, a big thank you to this fantastic community and, a bigger one, to the developers of this amazing and powerful programming language.

      Enjoy your night.

      Francesco 

      PS: I will post the code tomorrow ( the most updated code ), so you can see where I have been arrived and, nothing Warehouse_Management.xlsx

      Hi All,
      I'd like to move a window to the top of the stack without it being active.
      I think it's called z-order in programming?
      I've tried these 2 options (commenting out 1 at a time obviously), but the 1st doesn't seem to do anything, and the 2nd prevents it from being moved behind the other programs even after clicking on it and then clicking on another window behind it:
      Local $hWnd = WinGetHandle("[CLASS:MSPaintApp]")
      _WinAPI_SetWindowPos($hWnd, $HWND_TOP, 0, 0, 0, 0, BitOR($SWP_FRAMECHANGED, $SWP_NOMOVE, $SWP_NOSIZE))
      _WinAPI_SetWindowPos($hWnd, $HWND_TOPMOST, 0, 0, 0, 0, BitOR($SWP_FRAMECHANGED, $SWP_NOMOVE, $SWP_NOSIZE))
      What can I do to move something to the top of the z-order while allowing it to be manually moved back in the z-order?
      Thanks!

      Trying to use WM_COMMAND and WM_CONTEXTMENU in my GUI, and I'm having issue with the fact that WM_COMMAND doesn't fire when the mouse is over a listview or treeview.

      You can try to simulate my issue with the example code below. The WM_COMMAND will fire whenever the menu is created over the GUI background, but not when the menu is over the listview.


      #include <GuiMenu.au3> #include <GUIConstantsEx.au3> #include <WinAPI.au3> #include <WindowsConstants.au3> Global Enum $idOpen = 1000, $idSave, $idInfo _Main() Func _Main() ; Create GUI GUICreate("Menu", 400, 300) $hlistview = GUICtrlCreateListView("", 10, 10, 150, 280) GUISetState() ; Register message handlers GUIRegisterMsg($WM_COMMAND, "WM_COMMAND") GUIRegisterMsg($WM_CONTEXTMENU, "WM_CONTEXTMENU") ; Loop until user exits Do Until GUIGetMsg() = $GUI_EVENT_CLOSE EndFunc ;==>_Main ; Handle WM_COMMAND messages Func WM_COMMAND($hWnd, $iMsg, $iwParam, $ilParam) #forceref $hWnd, $iMsg, $ilParam Switch $iwParam Case $idOpen _WinAPI_ShowMsg("Open") Case $idSave _WinAPI_ShowMsg("Save") Case $idInfo _WinAPI_ShowMsg("Info") EndSwitch EndFunc ;==>WM_COMMAND ; Handle WM_CONTEXTMENU messages Func WM_CONTEXTMENU($hWnd, $iMsg, $iwParam, $ilParam) #forceref $hWnd, $iMsg, $ilParam Local $hMenu $hMenu = _GUICtrlMenu_CreatePopup() _GUICtrlMenu_InsertMenuItem($hMenu, 0, "Open", $idOpen) _GUICtrlMenu_InsertMenuItem($hMenu, 1, "Save", $idSave) _GUICtrlMenu_InsertMenuItem($hMenu, 3, "", 0) _GUICtrlMenu_InsertMenuItem($hMenu, 3, "Info", $idInfo) _GUICtrlMenu_TrackPopupMenu($hMenu, $iwParam) _GUICtrlMenu_DestroyMenu($hMenu) Return True EndFunc ;==>WM_CONTEXTMENU
      Can anyone help me out with this?

      Thanks!
