Show system menu of a hwnd

[Gintaras]

For me does not work too. But works if the window belongs to the same thread.

Code:

Copy      Help

\Dialog_Editor
function# hDlg message wParam lParam
if(hDlg) goto messages

if(!ShowDialog("Dialog36" &Dialog36)) ret

;BEGIN DIALOG
;0 "" 0x90C80A44 0x100 0 0 223 135 "Dialog"
;1 Button 0x54030001 0x4 120 116 48 14 "OK"
;2 Button 0x54030000 0x4 170 116 48 14 "Cancel"
;3 Button 0x54032000 0x0 0 121 48 14 "Button"
;END DIALOG
;DIALOG EDITOR: "" 0x2020100 "" ""
