Hi all:
I remember I saw this a long ago, but cannot find it.
I want that whenever I open an specific window, if an instance of it
is already open, just to give it focus and show it up front.
And the same also for my app, i.e. just have one instance running.
TIA
Pedro

If calling from a menu

METHOD MyWindow() CLASS MyShellWindow

IF SELF:oWin = NULL_OBJECT
SELF:oWin := MyWindow{ SELF }
ENDIF
SELF:oWin:Show()

You'll need to do our own cleanup if you close it via the 'x' button
Eg
METHOD CloseMyWin() CLASS MyShellWindow
IF SELF:oWin != NULL_OBJECT
SELF:oWin:Close()
SELF:oWin := NULL_OBJECT
ENDIF
RETURN

CYA

Hi Pedro, this is to get what you need for the application

local sNomeApplicazione as string
local hApplicazione as ptr
sNomeApplicazione:="Name of Your application"
hApplicazione := FindWindow(NULL_PSZ, PSZ(sNomeApplicazione))
IF (hApplicazione != NULL_PTR)
SetForegroundWindow(hApplicazione) //Mette in primo piano l'applicazione
gi� in esecuzione
ShowWindow(hApplicazione,SW_RESTORE) //Visualizza l'apllicazione se �
iconizzata
RETURN 0 //e chiude
ENDIF

Pedro,

If you want to allow the user to open more than one window but allow
only one instance of a particular window then do the following:

1. Create the open method on the ShellWindow (child windows call this)
2. In the above method call the GetAllChildren method of the
ShellWindow - this will return an array of all child windows
3. Scan the array returned in step 2 and check for the window you are
opening
4. If found use its SetFocus method, otherwise open it

Hope this helps.

Kevin
