Bot Posted June 5, 2010 Share Posted June 5, 2010 (edited) Hello,Here is the code I copied from the AutoIT manual. When the $hCombo has no additional style, the code works fine. But after I added a style $CBS_DROPDOWNLIST which set the state the combo to read-only, then the events $CBEN_ENDEDITA, $CBEN_ENDEDITW are missing. So how can I know if the user has selected an item from the control's drop-down list?Thanksexpandcollapse popup#include <GuiComboBoxEx.au3> #include <WindowsConstants.au3> #include <GuiConstantsEx.au3> Opt('MustDeclareVars', 1) $Debug_CB = False ; Check ClassName being passed to ComboBox/ComboBoxEx functions, set to True and use a handle to another control to see it work Global $hCombo _Main() Func _Main() Local $hGUI ; Create GUI $hGUI = GUICreate("ComboBoxEx Create", 400, 300) $hCombo = _GUICtrlComboBoxEx_Create ($hGUI, "This is a test|Line 2", 2, 2, 394, 268, $CBS_DROPDOWNLIST) GUISetState() GUIRegisterMsg($WM_NOTIFY, "WM_NOTIFY") _GUICtrlComboBoxEx_AddString ($hCombo, "Some More Text") _GUICtrlComboBoxEx_InsertString ($hCombo, "Inserted Text", 1) ; Loop until user exits Do Until GUIGetMsg() = $GUI_EVENT_CLOSE EndFunc ;==>_Main Func WM_NOTIFY($hWnd, $iMsg, $iwParam, $ilParam) Local $hWndFrom, $iIDFrom, $iCode, $tNMHDR $tNMHDR = DllStructCreate($tagNMHDR, $ilParam) $hWndFrom = HWnd(DllStructGetData($tNMHDR, "hWndFrom")) $iIDFrom = DllStructGetData($tNMHDR, "IDFrom") $iCode = DllStructGetData($tNMHDR, "Code") Switch $hWndFrom Case $hCombo Switch $iCode Case $CBEN_BEGINEDIT ; Sent when the user activates the drop-down list or clicks in the control's edit box. _DebugPrint("$CBEN_BEGINEDIT" & @LF & "--> hWndFrom:" & @TAB & $hWndFrom & @LF & _ "-->IDFrom:" & @TAB & $iIDFrom & @LF & _ "-->Code:" & @TAB & $iCode) Return 0 Case $CBEN_DELETEITEM _DebugPrint("$CBEN_DELETEITEM" & _GetComboBoxEx($ilParam)) Return 0 Case $CBEN_DRAGBEGINA, $CBEN_DRAGBEGINW Local $tInfo = DllStructCreate($tagNMCBEDRAGBEGIN, $ilParam) If DllStructGetData($tInfo, "ItemID") Then _DebugPrint("$CBEN_DRAGBEGIN" & _GetComboBoxEx($ilParam)) _DebugPrint("$CBEN_DRAGBEGIN" & @LF & "--> hWndFrom:" & @TAB & DllStructGetData($tInfo, "hWndFrom") & @LF & _ "-->IDFrom:" & @TAB & DllStructGetData($tInfo, "IDFrom") & @LF & _ "-->Code:" & @TAB & DllStructGetData($tInfo, "Code") & @LF & _ "-->ItemID:" & @TAB & DllStructGetData($tInfo, "ItemID") & @LF & _ "-->Text:" & @TAB & DllStructGetData($tInfo, "Text")) ; return is ignored Case $CBEN_ENDEDITA, $CBEN_ENDEDITW ; Sent when the user has concluded an operation within the edit box or has selected an item from the control's drop-down list.

martin Posted June 5, 2010 Share Posted June 5, 2010 Looks like something is wrong with the comboEx. According to msdn the notification should be sent when a user changes the selected text and there is nothing I can see to suggest that the style of the combo will affect that. You don't get $CBEN_BEGINEDIT either. Here is one way though not the best. expandcollapse popup#include <GuiComboBoxEx.au3> #include <WindowsConstants.au3> #include <GuiConstantsEx.au3> Opt('MustDeclareVars', 1) $Debug_CB = False ; Check ClassName being passed to ComboBox/ComboBoxEx functions, set to True and use a handle to another control to see it work Global $hCombo, $newval = False, $lbl1 _Main() Func _Main() Local $hGUI ; Create GUI $hGUI = GUICreate("ComboBoxEx Create", 400, 300) $hCombo = _GUICtrlComboBoxEx_Create($hGUI, "This is a test|Line 2", 2, 2, 394, 268, $CBS_DROPDOWNLIST) $lbl1 = GUICtrlCreateLabel("Selected = 0", 40, 40, 100, 22) GUISetState() GUIRegisterMsg($WM_NOTIFY, "WM_NOTIFY") _GUICtrlComboBoxEx_AddString($hCombo, "Some More Text") _GUICtrlComboBoxEx_InsertString($hCombo, "Inserted Text", 1) ; Loop until user exits Do If $newval Then GUICtrlSetData($lbl1, "selected = " & _GUICtrlComboBoxEx_GetCurSel($hCombo)) $newval = False EndIf Until GUIGetMsg() = $GUI_EVENT_CLOSE EndFunc ;==>_Main Func WM_NOTIFY($hWnd, $iMsg, $iwParam, $ilParam) Local $hWndFrom, $iIDFrom, $iCode, $tNMHDR $tNMHDR = DllStructCreate($tagNMHDR, $ilParam) $hWndFrom = HWnd(DllStructGetData($tNMHDR, "hWndFrom")) $iIDFrom = DllStructGetData($tNMHDR, "IDFrom") $iCode = DllStructGetData($tNMHDR, "Code") Switch $hWndFrom Case $hCombo Switch $iCode Case -807 $newval = True ; return is ignored EndSwitch EndSwitch Return $GUI_RUNDEFMSG EndFunc ;==>WM_NOTIFY Serial port communications UDF Includes functions for binary transmission and reception.printing UDF Useful for graphs, forms, labels, reports etc.Add User Call Tips to SciTE for functions in UDFs not included with AutoIt and for your own scripts.Functions with parameters in OnEvent mode and for Hot Keys One function replaces GuiSetOnEvent, GuiCtrlSetOnEvent and HotKeySet.UDF IsConnected2 for notification of status of connected state of many urls or IPs, without slowing the script.

You don't get $CBEN_BEGINEDIT either.Here is one way though not the best.Thanks for the answer but the event in your code is triggered every time the user move mouse over items or click on the combo, which generates lots of notification and it is inconvenient some way. Are there any workaround so that I can catch the event when the user has finally selected an item of the combo box? Link to comment Share on other sites More sharing options...
