AndyS01 Posted September 3, 2011 Share Posted September 3, 2011 When I try to send a message to my main GUI window, it never arrives. Here is my code:expandcollapse popup#Include <SendMessage.au3> #Include <GuiConstantsEx.au3> Opt("GUICloseOnESC", 1) ; ESC closes GUI Opt("GUIOnEventMode", 1) ; Change to OnEvent mode Opt('MustDeclareVars', 1) Opt("GUIEventOptions", 1) ;0=default, 1=just notification, 2=GuiCtrlRead tab index Global Const $myMESSAGE = 0x00099999 global $hWnd _Main() Func _Main() local $iBtn $hWnd = GUICreate("Test", 150, 50) $iBtn = GUICtrlCreateButton("Click Here", 10, 10, 100, 30) GUISetOnEvent($GUI_EVENT_CLOSE, "Event_GUIClose") GUICtrlSetOnEvent($iBtn, "handle_button_press") GUISetOnEvent($myMESSAGE, "handle_myMESSAGE") ; Setup a handler for my message GUISetState() While 1 Sleep(500) WEnd EndFunc ;==>_Main Func handle_button_press() ConsoleWrite("handle_button_press() entered" & @CRLF) _SendMessage($hWnd, $myMESSAGE) ; Send a $myMESSAGE message to the main gui EndFunc ;==>handle_button_press Func handle_myMESSAGE() ConsoleWrite("handle_myMESSAGE() entered" & @CRLF) EndFunc ;==>handle_myMESSAGE Func Event_GUIClose() ConsoleWrite("Event_GUIClose() entered" & @CRLF) Exit(1) EndFunc ;==>Event_GUIClose I've tried a standard message ($GUI_EVENT_CLOSE), but that didn't work either.

BrewManNH Posted September 3, 2011 Share Posted September 3, 2011 Try this line GUIRegisterMsg($WM_COMMAND, "handle_myMESSAGE") ; Setup a handler for my message In place of this line GUISetOnEvent($myMESSAGE, "handle_myMESSAGE") ; Setup a handler for my message and see if it works as you're expecting. You'll also need to add #include <WindowsConstants.au3> at the top of your script. If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.Give a programmer the correct code and he can do his work for a day.

Yashied Posted September 3, 2011 Share Posted September 3, 2011 (edited) Because you must use GUIRegisterMsg() instead of GUICtrlSetOnEvent(). #Include <GUIConstantsEx.au3> #Include <WinAPI.au3> Opt('GUIOnEventMode', 1) Global Const $WM_MYMESSAGE = _WinAPI_RegisterWindowMessage('MyMessage') Global $hWnd _Main() Func _Main() Local $iBtn $hWnd = GUICreate('Test', 150, 50) GUISetOnEvent($GUI_EVENT_CLOSE, 'Event_GUIClose') $iBtn = GUICtrlCreateButton('Click Here', 10, 10, 100, 30) GUICtrlSetOnEvent(-1, 'handle_button_press') GUIRegisterMsg($WM_MYMESSAGE, 'WM_MYMESSAGE') GUISetState() While 1 Sleep(500) WEnd EndFunc ;==>_Main Func handle_button_press() _SendMessage($hWnd, $WM_MYMESSAGE, 10, 99) EndFunc ;==>handle_button_press Func Event_GUIClose() Exit EndFunc ;==>Event_GUIClose Func WM_MYMESSAGE($hWnd, $iMsg, $wParam, $lParam) ConsoleWrite('WM_MYMESSAGE $wParam = ' & Number($wParam) & ' $lParam = ' & Number($lParam) & @CR) EndFunc ;==>WM_MYMESSAGE Edited September 3, 2011 by Yashied My UDFs: iKey | FTP Uploader | Battery Checker | Boot Manager | Font Viewer | UDF Keyword Manager | Run Dialog Replacement | USBProtect | 3D Axis | Calculator | Sleep | iSwitcher | TM | NetHelper | File Types Manager | Control Viewer | SynFolders | DLL Helper Animated Tray Icons UDF Library | Hotkeys UDF Library | Hotkeys Input Control UDF Library | Caret Shape UDF Library | Context Help UDF Library | Most Recently Used List UDF Library | Icons UDF Library | FTP UDF Library | Script Communications UDF Library | Color Chooser UDF Library | Color Picker Control UDF Library | IPHelper (Vista/7) UDF Library | WinAPI Extended UDF Library | WinAPIVhd UDF Library | Icon Chooser UDF Library | Copy UDF Library | Restart UDF Library | Event Log UDF Library | NotifyBox UDF Library | Pop-up Windows UDF Library | TVExplorer UDF Library | GuiHotKey UDF Library | GuiSysLink UDF Library | Package UDF Library | Skin UDF Library | AITray UDF Library | RDC UDF Library Appropriate path | Button text color | Gaussian random numbers | Header's styles (Vista/7) | ICON resource enumeration | Menu & INI | Tabbed string size | Tab's skin | Pop-up circular menu | Progress Bar without animation (Vista/7) | Registry export | Registry path jumping | Unique hardware ID | Windows alignment More...

AndyS01 Posted September 5, 2011 Author Share Posted September 5, 2011 Thank you, that worked very well. Also, thanks for including an example, it helped me understand the process. It might have saved me a lot of time if the help for _SendMessage() had a comment like "The $iMsg parameter value is for known windows message numbers. For a private message, you must register the private message using '_WinAPI_RegisterWindowMessage()'." Or in the example, show a private message being sent as well as a known windows message. Anyway, thanks again. Andy Link to comment Share on other sites More sharing options...
