correct use of GuiRegisterMsg(),$WM_COMMAND and $tagTBBUTTON

[maqleod]

ok, so I've looked in the help file under $WM_COMMAND, $tagTBBUTTON, GuiRegisterMsg() and have looked at the example _GuiCtrlToolbar_ClickButton() and I can't seem to find the way to do this. I've tried all sorts of things and most of the time I get a crash. When I searched the forum for performing actions when a toolbar button is pressed I only saw one posting with no source examples, which of course didn't help me much.

On to what I am trying to do. I just want to call a single function for each button pressed. Below is my toolbar build and what I was trying for the button press (i don't think you'll need more, but I'll post the rest if necessary, the code is almost 900 lines). I could use some pointers on how to do this right.

ok, I figured out something, though I don't know if it is the best way to do this, it at least works:

GUIRegisterMsg($WM_NOTIFY, "_WM_NOTIFY")

    Local $tNMTOOLBAR
    $tNMHDR = DllStructCreate($tagNMHDR, $lParam)
    $hwndFrom = DllStructGetData($tNMHDR, "hWndFrom")
    $code = DllStructGetData($tNMHDR, "Code")
    Switch $hwndFrom
        Case $toolbar
            Switch $code
                Case $NM_LDOWN
                    if $iItem = 1000 then
                        New()
                    EndIf
                    if $iItem = 1001 then
                        Open()
                    EndIf
                    if $iItem = 1002 then
                        Save()
                    EndIf
                    if $iItem = 1004 then
                        Print()
                    EndIf
                    if $iItem = 1005 then
                        Copy()
                    EndIf
                    if $iItem = 1006 then
                        Paste()
                    EndIf
                    if $iItem = 1007 then
                        Undo()
                    EndIf
                    if $iItem = 1008 then
                        Cut()
                    EndIf
                    if $iItem = 1009 then
                        ;Help()
                    EndIf
                Case $TBN_HOTITEMCHANGE
                    $tNMTBHOTITEM = DllStructCreate($tagNMTBHOTITEM, $lParam)
                    $i_idOld = DllStructGetData($tNMTBHOTITEM, "idOld")
                    $i_idNew = DllStructGetData($tNMTBHOTITEM, "idNew")
                    $iItem = $i_idNew
            EndSwitch
    EndSwitch
