You can do it over Threads and PosteEvent to Main program...

If you just want to display the elapsed time, just put a sticky and borderLess small window in the foreground and close it when done.

Code: Select all

Enumeration 
    #Win    
    #Timer_1_sec
    #Timer_5_sec
    #Btn_Quit
    #Win_Wait
    #Txt_Timer
EndEnumeration

OpenWindow(#Win, 0, 0, 640, 480, "", #PB_Window_SystemMenu | #PB_Window_ScreenCentered)
ButtonGadget(#Btn_Quit, WindowWidth(#Win) - 100, WindowHeight(#Win) - 40, 80, 25, "Quitter")
AddWindowTimer(#Win, #Timer_1_sec, 1000)
AddWindowTimer(#Win, #Timer_5_sec, 5000)

OpenWindow(#Win_Wait, 0, 0, 200, 100, "", #PB_Window_ScreenCentered | #PB_Window_BorderLess)
TextGadget(#Txt_Timer, 50, 50, 100, 15, "", #PB_Text_Center)
SetWindowColor(#Win_Wait, #Gray)
StickyWindow(#Win_Wait, #True)

Repeat
    Select WaitWindowEvent()
        Case #PB_Event_Timer
            Select EventTimer() 
                Case #Timer_1_sec
                    If IsWindow(#Win_Wait)
                        i + 1
                        SetGadgetText(#Txt_Timer, Str(i) + " Secs")
                    EndIf
                Case #Timer_5_sec
                    RemoveWindowTimer(#Win, #Timer_5_sec)
                    CloseWindow(#Win_Wait)
            EndSelect
            
        Case #PB_Event_CloseWindow
            Break
            
        Case #PB_Event_Gadget
            Select EventGadget()
                Case #Btn_Quit
                    Break   
            EndSelect
            
    EndSelect

I have sloved all my problems , post my code after

Code: Select all

Procedure DoEvents()
  Protected Event.l
  Repeat
    Event = WindowEvent()
    If Event = 0
      Sleep_(0)
    EndIf
  Until Event = 0
EndProcedure

;waiting window
Procedure SetLoadingWin(opeOrClo)
  If opeOrClo
    OpenWindow_waiting()
    StickyWindow(Window_waiting, #True)
    SetActiveWindow(Window_waiting)
    DisableWindow(Window_main, #True)
    DoEvents()
  Else
    DisableWindow(Window_main, #False)
    If IsWindow(Window_waiting)
      CloseWindow(Window_waiting)
    EndIf  
  EndIf
EndProcedure

may be of help to others

Something's very important:
1. There should always be only one event loop in the program.
2. Never use a delay in the event loop.
3. Only use WindowEvent() in special cases, otherwise always WaitWindowEvent(...)
4. Use EnableExplicit to avoid typing errors of variables

Added
5. Use not Long (Event.l) for default variables. Use Integer (Event.i). Integer is 32bit on x86 and 64bit on x64 programs.

P.S
Small example...

Update

Code: Select all
