WM_Notify Help

3 posts in this topic

Hello.

I am trying to single out double click events for different listviews and am not sure if using WinExists is the best method.

Func WM_NOTIFY($hWndGUI, $MsgID, $wParam, $lParam)
    #forceref $hWndGUI, $MsgID, $wParam
    Local $tNMHDR, $hwndFrom, $code, $i_idNew, $idFrom, $i_idOld
    Local $tNMTBHOTITEM, $hMenu, $aRet, $iMenuID = -1

    Local $hWndListView, $iWndListView, $jWndListView
    Local $tInfo, $uInfo, $vInfo

;~     MsgBox(0, ""

;~     $hWndListView = $nListView
;~     If Not IsHWnd($nListView) Then $hWndListView = GUICtrlGetHandle($nListView)
    If WinExists("PC Notes") Then $hWndListView = GUICtrlGetHandle($nListView)

;~     $iWndListView = $printers_listview
;~     If Not IsHWnd($printers_listview) Then $iWndListView = GUICtrlGetHandle($printers_listview)
    If WinExists("Multi-Printer Test") Then $iWndListView = GUICtrlGetHandle($printers_listview)

;~     $jWndListView = $network_mappings_listview
;~     If Not IsHWnd($network_mappings_listview) Then $jWndListView = GUICtrlGetHandle($network_mappings_listview)
    If WinExists("Network Drive Mappings") Then $jWndListView = GUICtrlGetHandle($network_mappings_listview)

    $tNMHDR = DllStructCreate($tagNMHDR, $lParam)
    $hwndFrom = DllStructGetData($tNMHDR, "hWndFrom")
    $idFrom = DllStructGetData($tNMHDR, "IDFrom")
    $code = DllStructGetData($tNMHDR, "Code")

    Switch $hwndFrom
        Case $hWndListView
            Switch $code
                Case $NM_DBLCLK ; Sent by a list-view control when the user double-clicks an item with the left mouse button
                    $tInfo = DllStructCreate($tagNMITEMACTIVATE, $lParam)

                    Local $iIndex = DllStructGetData($tInfo, "Index")
                    Local $sItemText = _GUICtrlListView_GetItemText($nListView, $iIndex)
                    If $sItemText <> "" Then
                        PCNotes_OpenItem()
                    EndIf
            EndSwitch

        Case $iWndListView
            Switch $code
                Case $NM_DBLCLK ; Sent by a list-view control when the user double-clicks an item with the left mouse button
                    $uInfo = DllStructCreate($tagNMITEMACTIVATE, $lParam)

                    Local $iIndex = DllStructGetData($uInfo, "Index")
                    Local $tItemText = _GUICtrlListView_GetItemText($printers_listview, $iIndex)
                    If $tItemText <> "" Then
                        Printers_WebConsole($tItemText)
                    EndIf
            EndSwitch

        Case $jWndListView
            Switch $code
                Case $NM_DBLCLK ; Sent by a list-view control when the user double-clicks an item with the left mouse button
                    $vInfo = DllStructCreate($tagNMITEMACTIVATE, $lParam)

                    Local $iIndex = DllStructGetData($vInfo, "Index")
                    Local $uItemText = _GUICtrlListView_GetItemText($network_mappings_listview, $iIndex)
                    If $uItemText <> "" Then
                        NetworkMappings_Initials_Edit()
                    EndIf
            EndSwitch

    EndSwitch
    Return $GUI_RUNDEFMSG

EndFunc   ;==>WM_NOTIFY

If I simply use the following, I get conflicts (sometimes wrong function executes):

$hWndListView = GUICtrlGetHandle($nListView)
$iWndListView = GUICtrlGetHandle($printers_listview)
$jWndListView = GUICtrlGetHandle($network_mappings_listview)

thanks in advance!

gcue,

Way too complicated! :)

You have the ControlID in the struct - so use it: :)

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

$hGUI = GUICreate("Test", 500, 500)

$nListView = GUICtrlCreateListView("ListView", 10, 10, 400, 100)
$printers_listview = GUICtrlCreateListView("Printers", 10, 120, 400, 100)
$network_mappings_listview = GUICtrlCreateListView("Network", 10, 230, 400, 100)

For $i = 1 To 3
    GUICtrlCreateListViewItem("Item " & $i, $nListView)
    GUICtrlCreateListViewItem("Printer " & $i, $printers_listview)
    GUICtrlCreateListViewItem("Network " & $i, $network_mappings_listview)
Next


GUISetState()

GUIRegisterMsg($WM_NOTIFY, "_WM_NOTIFY")

While 1

    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE
            Exit
    EndSwitch

WEnd


Func _WM_NOTIFY($hWndGUI, $MsgID, $wParam, $lParam)

    $tNMHDR = DllStructCreate($tagNMHDR, $lParam)
    $idFrom = DllStructGetData($tNMHDR, "IDFrom")
    $iCode = DllStructGetData($tNMHDR, "Code")

    Switch $iCode
        Case $NM_DBLCLK
            $tInfo = DllStructCreate($tagNMITEMACTIVATE, $lParam)
            Local $iIndex = DllStructGetData($tInfo, "Index")
            Switch $idFrom
                Case $nListView
                    Local $sItemText = _GUICtrlListView_GetItemText($nListView, $iIndex)
                    If $sItemText <> "" Then
                        ;PCNotes_OpenItem()
                        ConsoleWrite("PCNotes_OpenItem" & @CRLF)
                    EndIf
                Case $printers_listview
                    Local $tItemText = _GUICtrlListView_GetItemText($printers_listview, $iIndex)
                    If $tItemText <> "" Then
                        ;Printers_WebConsole($tItemText)
                        ConsoleWrite("Printers" & @CRLF)
                    EndIf
                Case $network_mappings_listview
                    Local $uItemText = _GUICtrlListView_GetItemText($network_mappings_listview, $iIndex)
                    If $uItemText <> "" Then
                        ;NetworkMappings_Initials_Edit()
                        ConsoleWrite("Network" & @CRLF)
                    EndIf
            EndSwitch
    EndSwitch

    Return $GUI_RUNDEFMSG

EndFunc   ;==>WM_NOTIFY

All clear? ;)
