A problem about MY_WM_COMMAND function

[52AT]

See the following code, double click the n.notepad in the listbox to open it and don't close it,

then single click any item in the listbox, immediately, another notepad was opened.

Why? and how solve it?

please help me, thanks

Code:

#include <GUIConstants.au3>

#NoTrayIcon

Global Const $WM_COMMAND = 0x0111

Global Const $LBN_SELCHANGE = 1

Global Const $LBN_DBLCLK = 2

Opt ("RunErrorsFatal", 0 )

$Form2 = GUICreate("Menu", 300, 300, 302, 218, -1, $WS_EX_TOPMOST)

GUISetIcon("D:\005.ico")

$GCCList = GuiCtrlCreateList("", 20, 70, 200, 200)

GuiCtrlSetData(-1, "n.notepad|b.List|c.Control|d.Here|g.Sample|f.List|h.Control|j.Here|h.here|", "a.menu")

$Label1 = GUICtrlCreateLabel("Menu", 20, 32, 140, 30)

GUICtrlSetFont(-1, 20, 400, 0, "Century Gothic")

GUIRegisterMsg($WM_COMMAND, "MY_WM_COMMAND")

GUISetState(@SW_SHOW)

While 1

$msg = GuiGetMsg()

Select

Case $msg = $GUI_EVENT_CLOSE

ExitLoop

EndSelect

WEnd

Func MY_WM_COMMAND($hWnd, $Msg, $wParam, $lParam)

$nNotifyCode = BitShift($wParam, 16)

$nID = BitAnd($wParam, 0x0000FFFF)

$hCtrl = $lParam

If $nID = $GCCList Then

Switch $nNotifyCode

Case $LBN_DBLCLK

If GUICtrlRead($GCCList) = 'n.notepad' Then Run('Notepad.exe')

Return 0

EndSwitch

EndIf

EndFunc

HI,

does it have to be done with GUIRegisterMsg($WM_COMMAND, "MY_WM_COMMAND") or would another solution also okay?

So long,

So

who has another solution to it? if had, please help me to modify the above code, so that i can cxecute some program through double clicking the listboxitem, but would not cxecute the program if i double clicked any area beyond the listbox

Far as I can tell, it doesn't work correctly when using a run command, at least this run command.

As a test I commented out the line with the run command, made a line that only sent output to the console (Using SciTE), at this point the double click worked as it should

Here's the test script

#include <GUIConstants.au3>
#NoTrayIcon
Global Const $WM_COMMAND = 0x0111
Global Const $LBN_SELCHANGE = 1
Global Const $LBN_DBLCLK = 2

Opt("RunErrorsFatal", 0)
$Form2 = GUICreate("Menu", 300, 300, 302, 218, -1, $WS_EX_TOPMOST)
GUISetIcon("D:\005.ico")
$GCCList = GUICtrlCreateList("", 20, 70, 200, 200)
GUICtrlSetData(-1, "n.notepad|b.List|c.Control|d.Here|g.Sample|f.List|h.Control|j.Here|h.here|", "a.menu")
$Label1 = GUICtrlCreateLabel("Menu", 20, 32, 140, 30)
GUICtrlSetFont(-1, 20, 400, 0, "Century Gothic")
GUIRegisterMsg($WM_COMMAND, "MY_WM_COMMAND")
GUISetState(@SW_SHOW)

While 1
    $msg = GUIGetMsg()
    Select
        Case $msg = $GUI_EVENT_CLOSE
            ExitLoop
    EndSelect
WEnd

Func MY_WM_COMMAND($hWnd, $msg, $wParam, $lParam)
    $nNotifyCode = BitShift($wParam, 16)
    $nID = BitAND($wParam, 0x0000FFFF)
    $hCtrl = $lParam
    If $nID = $GCCList Then
        Switch $nNotifyCode
            Case $LBN_DBLCLK
                If GUICtrlRead($GCCList) = 'n.notepad' Then ConsoleWrite(_DebugHeader("$LBN_DBLCLK"))
;~              If GUICtrlRead($GCCList) = 'n.notepad' Then Run('Notepad.exe')
        EndSwitch
    EndIf
EndFunc   ;==>MY_WM_COMMAND

Func _DebugHeader($s_text)
    Return _
            "!===========================================================" & @LF & _
            "+===========================================================" & @LF & _
            "-->" & $s_text & @LF & _
            "+===========================================================" & @LF
EndFunc   ;==>_DebugHeader

Hi,

question could be why a listbox? Why not using a button or some other control?

I think I can make the interface more succinct in this way

Since MY_WM_COMMAND doesn't work correctly when using a run command, who has other codes can make me cxecute some program through double clicking the listboxitem, but would not cxecute the program if i double clicked any area beyond the listbox

I would suggest looking in the Search Option for "Double Click" in titles only... That's always the best place start before posting a question like in the last post.

Edit:

Now you will see more than one option.

The problem with WM_COMMAND has brought to the devloper(s) attention and added to the list of of things to look at.
