nowait

[Silvio.Falconi]

I open dbf with tdatabase why make error ?


is it possible to use a dialog in source (and not in resource) using the NOWAIT clause?

Meaning what

DEFINE DIALOG oDlg SIZE nWd, nHt PIXEL TRUEPIXEL;
FONT oFont COLOR CLR_BLACK, DLG_nColorDlg

ACTIVATE DIALOG oDlg NOWAIT



RETURN (NIL)

Hello, you must show how you are doing the OPENING of the Database, because the ERRSYSW.prg is saying that the OPEN AREA IS NOT IN USE.

Hola, debes mostrar como estas haciendo la APERTURA de la Base de Datos, porque el ERRSYSW.prg esta diciendo que el AREA ABIERTA NO ESTÁ EN USO.

And why does this DIALOGUE need to be NOWAIT?

¿Y por qué este DIÁLOGO necesita ser NOWAIT?

Regards, saludos.

Se que no es lo que necesitas porque usas tdatabase, pero tal vez te de un hilo para seguir.

Code: Select all | Expand

#include "FiveWin.ch"
static oWnd
static lEnd := .f., nArea
//----------------------------------------------------------------------------//
function Main()
nArea := 0
   DEFINE WINDOW oWnd TITLE "Dialogo NoWait"

   @ 2,  2 BUTTON "&Start" SIZE 80, 20 ACTION StartTest() 
   @ 2, 20 BUTTON "&Info" SIZE 80, 20 ACTION MsgInfo(select())
   @ 2, 40 BUTTON "&Close Area" SIZE 80, 20 ACTION dbclosearea(select()) // Esto es para que de error al querer volver a ese dialogo nowait
   ACTIVATE WINDOW oWnd MAXIMIZED
return nil

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

function StartTest()
   local oDlg
   local oBrw   , n
   nArea ++
   n := nArea
   USE Customer ALIAS "customer"+ALLTRIM(STR(nArea)) SHARED NEW
   INDEX ON Field->State TO State
   SET ORDER TO "State"
      DEFINE DIALOG oDlg TITLE "No Wait Customer"+ALLTRIM(STR(nArea)) FROM 10, 10 TO 23, 70 RESIZABLE
      @ 01,01 XBROWSE oBrw OF oDlg ;
        LINES STYLE FLAT NOBORDER ;
        COLUMNS "State","City", "Last", "First" ;
        HEADERS "State","City", "Last", "First" PIXEL SIZE 200,70
      oBrw:nMarqueeStyle = MARQSTYLE_HIGHLROW
      oBrw:CreateFromCode()  
      oBrw:bGotFocus := {|| dbselectarea(oBrw:cAlias)}
      ACTIVATE DIALOG oDlg NOWAIT VALID(Cerrar(n))
      SysRefresh()
return nil

STATIC FUNCTION Cerrar(n)
dbclosearea( "customer"+ALLTRIM(STR(nArea)))
RETURN .t. 
//----------------------------------------------------------------------------//
 

Los xbrowse con dialogos nowait funcionan bien, pero si cerramos un area de un dialogo que esta activo, ahi obtenemos el error.
Intuyo que por ese lado viene el problema

Yes.
But close the oDbf in the valid clause but not after activate command.

This works for modal dialigs ( not nowait):

Code: Select all | Expand

   ACTIVATE DIALOG oDlg 
   oDbf:Close()
return nil
 

But this does not work for non-midal ( NOWAIT) dialogs.
Results in the same error as above.

WRONG

Code: Select all | Expand

   ACTIVATE DIALOG oDlg NOWAIT
   oDbf:Close()
return nil
 

CORRECT WAY

Code: Select all | Expand

   ACTIVATE DIALOG oDlg NOWAIT ;
      VALID ( oDbf:Close(), .T. ) 
return nil

thanks I resolved with Cesar

WRONG

Code: Select all | Expand

   ACTIVATE DIALOG oDlg NOWAIT
   oDbf:Close()
return nil
 

CORRECT WAY

Code: Select all | Expand

   ACTIVATE DIALOG oDlg NOWAIT ;
      VALID ( oDbf:Close(), .T. ) 
return nil

CORRECT WAY

   ACTIVATE DIALOG oDlg NOWAIT ;
      VALID ( oDbf:Close(), .T. ) 
return nil
 

Nages,
I made as you wrote me

Code: Select all | Expand

  
ACTIVATE DIALOG oDlg NOWAIT ;
      VALID ( oDbf:Close(), .T. )
 

but sometimes have the same error when there is only one dialog opened
it not happened with more dialog opened with same or more dbf

it happen because on xbrowse I have a small menupopup

Code: Select all | Expand

 
  oBrw:bRClicked := {|nRow,nCol| MenuContextual(nRow,nCol,oDlg,oBrw,oArticoli) }
 

and the function MenuContextual

Code: Select all | Expand

Function MenuContextual(nRow,nCol,oDlg,oBrw,oDbf )
   local oMenu

           MENU oMenu POPUP 2015

       
           MENUITEM "al primo record  " +space(6)+ CHR(VK_TAB) + "Ctrl+Home";
              MESSAGE "Mostra la lista dal primo record";
              RESOURCE "GRID_TOP";
              ACTION oBrw:KeyDown(VK_HOME, 0)  WHEN oDbf:OrdKeyCount() > 0

            MENUITEM "a pagina prec.  " +space(6)+ CHR(VK_TAB) + "Pag. Sù";

              MESSAGE "Mostra la lista muovendosi  al record precedente ";

              MESSAGE "Mostra la lista muovendosi al record avanti";
                RESOURCE "GRID_DOWN";
              ACTION oBrw:KeyDown(VK_DOWN, 0)  WHEN oDbf:OrdKeyCount() > 0

            MENUITEM "a pag. avanti  " +space(6)+ CHR(VK_TAB) + "Pag. Giù";
              MESSAGE "Mostra la lista della pagina avanti";
               RESOURCE "GRID_NEXT";
              ACTION oBrw:KeyDown(VK_NEXT, 0)  WHEN oDbf:OrdKeyCount() > 0

            MENUITEM "all'ultimo record  " +space(6)+ CHR(VK_TAB) + "Ctrl+End";
              MESSAGE "Mostra la lista all'ultimo record";

         ENDMENU
   ACTIVATE POPUP oMenu OF oDlg AT  oBrw:nTop+nRow, oBrw:nLeft+nCol
