Help with $WM_COMMAND

Recommended Posts


Hi ppl, i need a little help!

I'm trying to understand how to use the GuiRegisterMsg(), and in this teste above:

why it capture the click on Button, but not capture the click in the tab?

how to use it correctly?

#include <GuiTab.au3>
#include <WindowsConstants.au3>
#include <GUIConstantsEx.au3>
$Gui = GUICreate("Test", 300, 300, -1, -1)
$tab = _GUICtrlTab_Create($Gui, 0, 0, 300, 300)
_GUICtrlTab_InsertItem($tab, 0, "Tab 1")
$button = GUICtrlCreateButton("Button test", 100, 100)
_GUICtrlTab_InsertItem($tab, 1, "Tab 2")
_GUICtrlTab_SetItem($tab, 0)
While 1
Switch GUIGetMsg()
Func _WM_COMMAND($hWnd, $msg, $wParam, $lParam)
Local $nID = BitAND($wParam, 0x0000FFFF)
Switch $nID
  Case $button
   MsgBox(0,'','Click on Button')
  Case $tab
   MsgBox(0,'','Click on Tab')

thanks a lot!

It is because you have created the tab using the GUITab UDF. This returns a handle and not a ControlID. Within your message handler you are testing for the ControlID - as the tab does not have one, you do not detect it. ;)

To detect clicks on UDF created tabs you need to register WM_NOTIFY - look at the Help file for _GUICtrlTab_Create to see how to do it. :)

      I have read the Tutorial. Used the Help File and used an example script by @Melba23.  I am still struggling.
      To use GUIRegisterMsg one needs the following
      a control in the GUI a GUIRegisterMsg instruction in the GUI to link the control to the WM_COMMAND function a Case statement in the Switch loop to run it a WM_COMMAND function and a processor function... Mine looks like this
      ;~ ; QuickSearch combo box $g_cbQwkSrch = GUICtrlCreateCombo("", 8, 26, 180, 17) ; start blank GUICtrlSetTip($g_cbQwkSrch, "Type to search", "QuickSearch") GUIRegisterMsg($WM_COMMAND, "__WM_COMMAND_QWKSEARCH_CMB") ;------------------------------------ ; use in Switch Loop ;~ ; QuickSearch Case $g_cbQwkSrch ConsoleWrite("221 Case $g_cbQwkSrch" & @CRLF) ;-------------------------------------- Func _QwkSrch_Edit_Changed() ConsoleWrite("41 _QwkSrch_Edit_Changed" & @CRLF) ; Autocomplete the edit _GUICtrlComboBox_AutoComplete($g_cbQwkSrch) ; Change the label to match the autocompleted edit entry EndFunc ;==>_QwkSrch_Edit_Changed Func __WM_COMMAND_QWKSEARCH_CMB($hWnd, $iMsg, $wParam, $lParam) ; GUIRegisterMsg($WM_COMMAND, "__WM_COMMAND_QWKSEARCH_CMB") ConsoleWrite("50 _WM_COMMAND_QWKSEARCH_CMB fired " & @CRLF) Local $Found = '' #forceref $hWnd, $iMsg If $lParam = GUICtrlGetHandle($g_cbQwkSrch) And BitShift($wParam, 16) = $CBN_EDITCHANGE Then ; Our combo edit content has changed ; get data from source ---------------------------- Local $datafromsource = fFindFilesForQuickSearch($stringtofind) ; datafromsource convert to Combo friendly format ; Add data to combo _GUICtrlComboBox_BeginUpdate($g_cbQwkSrch) GUICtrlSetData($g_cbQwkSrch, $Found) _GUICtrlComboBox_EndUpdate($g_cbQwkSrch) EndIf _QwkSrch_Edit_Changed() ; Action this function EndIf EndFunc ;==>_WM_COMMAND_QWKSEARCH_CMB Func fFindFilesForQuickSearch($stringtofind) ; helper function for QuickSearch ; get data here Return $aResult EndFunc ;==>fFindFilesForQuickSearch Now the following:
      Can I declare the variable $g_cbQwkSrch in Global, then use in multiple functions - reassigning different combo's to it as I go along? Should GUIRegisterMsg be expressly de-registered, or does that happen automatically at GuiDelete()? Where is the best/correct place to call GUIRegisterMsg? With the creation of its control, before the GUISetState, or before the start of the loop? The Help File contains this entry, what is the intent?  Must this always be called with four args, or a max of four...   !!! To make the user function workable you have to define it with maximum 4 function parameters otherwise the function won't be called !!!

      Best example I could find is here
      The way I understand this, the standard Windows messages, such as Left/Right Click etc are covered by AutoIt macros, but the real power is locked up inside this WM_NOTIFY .  I have tried, but I am not even sure I understand what I am looking at.
      I need help understanding this.  What I am looking for is Help file or Tutorial explaining how this works?  
      Perhaps if there is a script showing both the working of an AutoIt macro and the WM_NOTIFY  in action, it would help.
      Right now I am so lost, I do not even know what are the right questions to ask.  One issue I have is on ListViews, how to combine the "Click" of a line with a standard Switch loop?  Like users clicks a line, then get the loop to detect the click and ;do something ...
      Any ideas?

        Hi all,
      I know this is a crazy idea. But i think it might be a help for somebody. The name of this program is GRM Helper. i.e. GUIRegisterMsg Helper. 
      This program helps you to write the guiregistermsg function code automatically. You can choose a control from the combo box. Then all events of that control will be displayed in a list view. You can click on an event for it;s details. Then you can check the events which you want to include in your code. Then type some details like; 1) Your control's handle. 2) Line number for inserting GUIRegisterMsg code. 3) Line number for inserting main function.
      And press the "Isert To SciTE" button. Your code is ready in scite.
      Here is the program.
      Updated Version 1.1
      GRM Helper V1.1.zip

      The code written by this program.
      GUIRegisterMsg($WM_COMMAND, "WM_COMMAND") Func WM_COMMAND($hWnd, $iMsg, $wParam, $lParam) #forceref $hWnd, $iMsg Local $hWndFrom, $iIDFrom, $iCode, $hWndListBox If Not IsHWnd($Sample) Then $hWndListBox = GUICtrlGetHandle($Sample) $hWndFrom = $lParam $iIDFrom = BitAND($wParam, 0xFFFF) ; Low Word $iCode = BitShift($wParam, 16) ; Hi Word Switch $hWndFrom Case $Sample, $hWndListBox Switch $iCode Case $LBN_ERRSPACE ; Insert your code here Case $LBN_SELCHANGE ; Insert your code here Case $LBN_DBLCLK ; Insert your code here Case $LBN_SELCANCEL ; Insert your code here EndSwitch EndSwitch Return $GUI_RUNDEFMSG EndFunc ;==>WM_COMMAND

      Hi all,
      I am playing with a combo box. The code from help file is working. But the code i wrote is not working. Help file uses "_GUICtrlComboBox_Create" for creating combo box. But i used native "GUICtrlCreateCombo". Then i replaced my native combo creation function with the UDF. Then my code worked. I think the hi word and low word parameters are the problem. 
      Here is my code.
      #include <ComboConstants.au3> #include <GUIConstantsEx.au3> #include <WindowsConstants.au3> Local $sCMB_Items = "Apple|Orange|Mango|Banana|Grape" #Region ### START Koda GUI section ### Form= Global $hForm1 = GUICreate("Form1", 283, 188, 312, 166) Global $hCombo1 = GUICtrlCreateCombo("", 40, 48, 185, 25, BitOR($CBS_DROPDOWN,$CBS_AUTOHSCROLL)) GUISetState(@SW_SHOW) #EndRegion ### END Koda GUI section ### GUICtrlSetData($hCombo1, $sCMB_Items) GUIRegisterMsg($WM_COMMAND, "WM_COMMAND") While 1 $nMsg = GUIGetMsg() Switch $nMsg Case $GUI_EVENT_CLOSE Exit EndSwitch WEnd Func WM_COMMAND($hWnd, $iMsg, $wParam, $lParam) #forceref $hWnd, $iMsg Local $hWndFrom, $iIDFrom, $iCode $hWndFrom = $lParam $iIDFrom = BitAND($wParam, 0xFFFF) ; Low Word $iCode = BitShift($wParam, 16) ; Hi Word Switch $hWndFrom Case $hCombo1 Switch $iCode Case $CBN_DBLCLK ; Insert your code here MsgBox(0,"","$CBN_DBLCLK") Case $CBN_DROPDOWN ; Insert your code here MsgBox(0,"","$CBN_DROPDOWN") Case $CBN_EDITCHANGE ; Insert your code here MsgBox(0,"","$CBN_EDITCHANGE") Case $CBN_SELCHANGE ; Insert your code here MsgBox(0,"","$CBN_SELCHANGE") EndSwitch EndSwitch Return $GUI_RUNDEFMSG EndFunc ;==>WM_COMMAND And this is the code from help file. Slightly modified. But working
