If you for example specify the MB_HELP flag in the MessageBox the parent window gets the WM_HELP message when the user clicks the help button. If you don't specify a parent you will never receive it.

[MrCreatoR]

could it be a bug - and - what is that param in msgbox for ?

No, and it's uses as the parent for msgbox dialog.

help fille should be updated.

To what?

sorry if i am stupid: but how can you specify the flag to the normal MsgBox ? can you make a simple example please ?

in this case, GeoSoft, help fille should be updated.

Trying to keep documentation (All developers hate that part) updated so that everyone understands it is somethink akin to attempting to write "Idiot Proof" code. All is well and good until you encounter a bigger idiot than what your calculations had thought possible.

Probably because someone (for their own reasons) added it as a feature request and the Dev team, in their never ending quest to keep everyone happy(you can stop laughing now Valik), added it in. I keep forgetting that it's even available. Edited January 4, 2009 by GEOSoft

Yeah sure.

#include <windowsconstants.au3>
Global Const $MB_HELP=0x00004000

$hwnd=GUICreate("Test")

GUIRegisterMsg($WM_HELP,"help")

MsgBox($MB_HELP,"","",Default,$hwnd)



Func help($hWnd, $Msg, $wParam, $lParam)
    ToolTip("I need help!")
    Return "GUI_RUNDEFMSG"
EndFunc

Now try without the hwnd param

Maybe to avoid something like this (besides what monoceres said):

#include <WindowsConstants.au3>

$gui = GUICreate("msgbox question", 200, 200, Default, Default, Default, $WS_EX_TOPMOST)
$m = GUICtrlCreateButton("MsgBox", 20, 20)
;$f=GUICtrlCreateButton("FileOpenDialog", 20,60)
GUISetState()
Do
    $msg = GUIGetMsg()
    If $msg = $m Then MsgBox(0, "", "blah blah");,0,$gui)
;If $msg=$f Then FileOpenDialog("placed",@SystemDir,"All (*.*)",7,"",$gui)
Until $msg = -3

But then you can't get help while the MessageBox is open.

[jennico]

ah, it doesn*t close. now i got the point. !

Specifying the parent of a MsgBox (or other dialog) also stops a separate taskbar item from showing up just for the dialog.

ie:

$gui = GUICreate("msgbox question", 200, 200, Default, Default, Default)
$m = GUICtrlCreateButton("MsgBox, regular", 20, 20)
$m1= GUICtrlCreateButton("MsgBox with parent", 20,60)
GUISetState()
Do
    $msg = GUIGetMsg()
    If $msg = $m Then MsgBox(0, "", "Look at the taskbar !!!" & @CRLF & "You'll see the taskbar item for your original script" & @CRLF & "and you'll see me!")
        If $msg = $m1 Then MsgBox(0, "", "Look at the taskbar !!!" & @CRLF & "You'll see the taskbar item for your original script only"  & @CRLF & @CRLF & "I'm NOT there!",0,$gui)
Until $msg = -3

Gives a more professional look to your apps!

I know this thread is quite old but I noticed a minor bug and just wanted to tell you about it.

Func _MsgBoxEx($iFlag, $sTitle, $sText, $iLeft=Default, $iTop=Default, $iTimeOut=Default, $hWnd=Default)
    ...
    MsgBox($iFlag, $sTitle, $sText, $iTimeOut, $hWnd)
EndFunc

This should be

Func _MsgBoxEx($iFlag, $sTitle, $sText, $iLeft=Default, $iTop=Default, $iTimeOut=Default, $hWnd=Default)
    ...
    Return MsgBox($iFlag, $sTitle, $sText, $iTimeOut, $hWnd)
EndFunc

to return the ID of the pressed button.
