Olá Antonio,

Estou usando DIALOG dentro de uma WINDOW MDICHILD e está me ocorrendo erro de GPF. Simulei o erro usando o sample \fwh\samples\testmdix.prg. Veja o exemplo abaixo:

Code: Select all

// This is an example of how to place controls inside a MDIChild
// from a dialog built from source code

#include "FiveWin.ch"

static oWnd

//----------------------------------------------------------------------------//

function Main()

   local oBar

   SET _3DLOOK ON

   DEFINE WINDOW oWnd TITLE "MDIChilds from resources" MDI

   DEFINE BUTTONBAR oBar _3D OF oWnd

   DEFINE BUTTON OF oBar ACTION ( Child(), MsgInfo( oWnd:oWndClient:aWnd[ 1 ]:cCaption ) )

   ACTIVATE WINDOW oWnd

return nil

//----------------------------------------------------------------------------//

function Child()

   local oWndChild, oDlg, oBtn
   local cName := "Testing..."

   DEFINE WINDOW oWndChild MDICHILD OF oWnd ;
      COLOR "N/W"

   oWndChild:bGotFocus  = { || oDlg:SetFocus() }

   DEFINE DIALOG oDlg FROM 0, 0 TO 10, 20 ;
      STYLE WS_CHILD OF oWndChild

   oDlg:bLostFocus = { || MsgBeep() }

   @ 2, 2 BUTTON "&Ok" OF oDlg ACTION MsgInfo( "Click" )

   ACTIVATE DIALOG oDlg NOWAIT ;  // It has to be NonModal --> NOWAIT clause
      ON INIT oDlg:Move( 0, 0 )

   ACTIVATE WINDOW oWndChild ;
      ON INIT oWndChild:SetSize( oDlg:nWidth, oDlg:nHeight )

   A += 1   && Aqui simulo o erro

return nil

//----------------------------------------------------------------------------//

Ao executar a linha "A += 1" é retornada a tela de erro padrão de FWH e em seguida ocorre o erro de GPF abaixo:

Qual seria a solução para este GPF ?

Gracias,

Rossine.

Rossine,

Please add these lines in source\function\errsysw.prg:

Code: Select all

   if lRet == nil .or. ( !LWRunning() .and. lRet )
      SET RESOURCES TO
      ErrorLevel( 1 )
      // NEW !!!
      for n = 1 to Len( GetAllWin() )
         if ValType( GetAllWin()[ n ] ) == "O"
            GetAllWin()[ n ]:UnLink()
         endif   
      next
      // NEW !!!
      QUIT              // must be QUIT !!!
   endif

Antonio,

Quando clico em "Quit" o sistema é abortado normalmente, sem ocorrer o erro de GPF

...mas se clico em "Retry" aí ocorre o erro de GPF novamente

Gracias,

Rossine.

Esto sería más correcto:

Code: Select all

for n = Len( GetAllWin() ) to 1 step -1 
   if ValType( GetAllWin()[ n ] ) == "O" 
      GetAllWin()[ n ]:End()
   endif 
next

Olá Antonio,

Como estas mudanças agora funcionou 100%

Code: Select all

...
*  ErrorBlock( {|e| MsgStop( ErrorMessage(e) + " from Errorsys, line:" + ;
*                            Str( ProcLine( 1 ), 3 ) ), __quit() } )

   ErrorBlock( { |e| exit_all(e,.t.) } )
...

Code: Select all

...
   ACTIVATE DIALOG oDlg CENTERED ;
      ON PAINT DrawBitmap( hDC, hLogo, 6, 6 )

   DeleteObject( hLogo )

*   if lRet == nil .or. ( !LWRunning() .and. lRet )
*      SET RESOURCES TO
*      ErrorLevel( 1 )
*      QUIT              // must be QUIT !!!
*   endif

   if lRet == nil .or. ( !LWRunning() .and. lRet ) 
      exit_all( e, .f. )
   endif 

return lRet
...

Code: Select all

...
static function exit_all( e, lRetry )

if lRetry
   MsgStop( ErrorMessage(e) + " from Errorsys, line:" + ;
                                Str( ProcLine( 1 ), 3 ) )
endif

SET RESOURCES TO
ErrorLevel( 1 )

for n = Len( GetAllWin() ) to 1 step -1 
   if ValType( GetAllWin()[ n ] ) == "O" 
      GetAllWin()[ n ]:End() 
   endif 
next 
sysrefresh()
QUIT

//----------------------------------------------------------------------------//
...

Verifique por favor se elas estão corretas ok ?

Obrigado,
