Parameter for Timeout

[Jimmy]

hi,

und Xbase++ i have 4th Parameter for Timeout

Code: Select all | Expand

   DO WHILE !lExit = .T.
      nEvent := AppEvent( @mp1, @mp2, @oXbp, nTimeOut )
      DO CASE
          CASE nEvent == xbe_None
            // Timeout
            DoTimeOut()
            RETURN

         CASE nEvent == xbeP_Keyboard .AND. mp1 == xbeK_ESC
            EXIT
      OTHERWISE
         oXbp:handleEvent( nEvent, mp1, mp2 )
      ENDCASE
   ENDDO

this Way a Windows / Dialog can be "close" when "Timeout" is reach

how to use that Concept under Fivewin

hello, look \samples\GAME.PRG

hi,

thx for Answer

to use a TIMER is not a Solution

4th Parameter of AppEvent ( = ACTIVATE ) does react on "NO Event" within "Timeout"
i can check

Code: Select all | Expand

          CASE nEvent == xbe_None
            // Timeout
            DoCloseWindowAndDBF()

and "close" Window/Dialog and DBF

"NO Event" mean that there is no "Input" or "Mouse-Move" in Event-Queue of App

[karinha]

DoCloseWindowAndDBF() ???

I don't understand? You show a piece of program. There's no way to guess what you want to do! Show an EXAMPLE in practice.

¿No entiendo? Muestras una parte del programa. ¡No hay forma de adivinar lo que quieres hacer! Muestre un EJEMPLO en la práctica.

Gracias, thanks.

hi,

Show an EXAMPLE in practice.

will Xbase++ CODE help you to understand

Code: Select all | Expand

PROCEDURE DoCloseWindowAndDBF()
   IF USED()
      nRecordWork := RECNO()   // remember last work
      CLOSE
   ENDIF
   lExit := .T.                // Field wide STATIC
RETURN

---

AppEvent() is like ACTIVATE and 4th Parameter is for TIMEOUT
AppEvent() get Events when Keyboard "input" or Mouse move or other Action

if used 4th Parameter of AppEvent it include "Timeout"
when "no Event" arrive and after "timeout" is over, it send Event xbe_None

now i can react on xbe_None and call "DoCloseWindowAndDBF()"

---

my Question is : how can i "simulate" 4th Parameter of AppEvent() under Fivewin

[karinha]

Code: Select all | Expand

PROCEDURE DoCloseWindowAndDBF()

   IF USED()

      nRecordWork := RECNO()   // remember last work

      GOTO( nRecordWork )
 
      CLOSE( cAlias ) // Name ALIAS()

      // oDlg:End() // static
      // oWnd:End() // etc

   ENDIF

   lExit := .T.                // Field wide STATIC

RETURN NIL

hi,

Thx for Answer.

i do not have Problem to write CODE for DoCloseWindowAndDBF()

my "Problem" is to get a "Timeout" which will "activate" call of DoCloseWindowAndDBF() when "Timeout"

---

HMG use DOEVENTS which "seem" me equivalent to Fivewin SysRefresh()

it use TranslateMessage( &Msg ) and DispatchMessage( &Msg ) to get Event from Queue

Code: Select all | Expand

HB_FUNC ( DOEVENTS )
{
   MSG Msg;
   HWND hDlgModeless = NULL;
   while( PeekMessage ( &Msg, NULL, 0, 0, PM_REMOVE ) )
   {   
      hDlgModeless = GetActiveWindow();   // this is not better way of take Handle of Modeless Dialog Box

      if ( hDlgModeless == NULL || !IsDialogMessage ( hDlgModeless, &Msg ) )   // ADD June 2015
      {
         TranslateMessage ( &Msg );
         DispatchMessage  ( &Msg );
      }
   }
}
 

if there is "NO Event" and "Timeout" is over than it should send "itself" a Event like xbe_None

[karinha]

Holá,

Jimmy, make a COMPLETE EXAMPLE with all the FUNCTIONS, your way of programming is very complex, and I think you mix another LIB with FIVEWIN. It's very difficult to understand you.

Jimmy, haz un EJEMPLO COMPLETO con todas las FUNCIONES, tu forma de programar es muy compleja, y creo que mezclas otra LIB con FIVEWIN. Es muy difícil entenderte.

Gracias, thanks.

hi,

sorry, you still does not understand my Question what Upload Sample show.
that CODE only work with Xbase++ ... i have NO harbour Sample (yet)

---

Windows Screen-Saver or Energy.Saving have a "Timeout" like i want to have in my harbour App
Xbase++ CAN use 4th Parameter for "Timeout" but HMG or Fivewin / harbour have NO Equivalent as i know

as i remember right i had a "Screen-Saver" in my Cl*pper App but i can´t find that SOURCE any more

---

New Question : how to build Screen-Saver for Fivewin
i do not mean "Animation", i mean how to detect "Timeout" of App so Screen-Saver will be "activate"

Hi Jimmy, I think you're looking for this function in harbour hb_idle_add( bBlock )

Code: Select all | Expand

PROCEDURE Main()

   CLS

   ? "DEFAULT IDLEREPEAT =", Set( _SET_IDLEREPEAT )
   ?
   ? "Idle Block should be displayed multiple times until key or 10 seconds elapsed!"
   ? "Press any key to begin..."
   ?
   Inkey( 0 )

   hb_idleAdd( {|| QOut( "Idle Block" ) } )
   Inkey( 2 )

   Set( _SET_IDLEREPEAT, .F. )

   hb_idleAdd( {|| QOut( "Idle Block2" ) } )

   CLS
   ? "Idle Block & Block-2 should display ONCE! while waitning for key or 10 seconds elapsed!"
   ?
   Inkey( 2 )

   ?
   ? "Again - Idle Block & Block-2 should display ONCE! while waitning for key or 10 seconds elapsed!"
   ?
   Inkey( 2 )
   ?

   RETURN

hi,

I think you're looking for this function in harbour hb_idle_add( bBlock )

thx for Answer.

i have Problem with "Console" App ... it does not show anything on Screen ...
have try REQUEST HB_GT_WIN_DEFAULT but got "unknown Function" ...

[Jimmy]

hi,

see if it helps:

YES, your Sample work in right Direction.

instead of Screen-Save it should "close" WINDOWS / DIALOG and DBF if USED()
Thx for Idea, now i can work in that Direction

[Marc Venken]

Karinha,

Very usefull piece of code.

If a program is left open bij a user (like so ofthen) the code will show the screensaver (with a message that a program need to be closed) It even works if you are working in a other program. Nice and thanks

if the screensaver stays active for xxx time, you could even force a close all and close dialog and terminate the program. Interesting idea

[Jimmy]

hi Marc,

that is exact the Idea for "File-based" System and Network to reduce SMB Problem
