When using several threads, is it then possible to access files, from within the threads, which were opened before calling the threads?

Andy

Its possible:

Code: Select all

Procedure ReadOpenedFile(FileNum.l)
UseFile(FileNum)
MessageRequester("string",ReadString(),0)
CloseFile(FileNum)
EndProcedure



If OpenWindow(0,100,150,450,200,#PB_Window_SystemMenu,"Test")
  CreateGadgetList(WindowID())
  ButtonGadget(1,200,100,50,25,"Test")
  Repeat
    EventID=WaitWindowEvent()
    
    Select EventID
    
      Case #PB_EventGadget
        Select EventGadgetID()
          Case 1
            If OpenFile(0,"somedata.txt");create a file and store some string
              WriteString("1234567")
              CloseFile(0)
            EndIf
            
            If OpenFile(1,"somedata.txt");open the file and call the procedure in a thread
              ThreadID = CreateThread(@ReadOpenedFile(),1)
            EndIf
            
        EndSelect
    
    EndSelect
    
  Until EventID=#PB_EventCloseWindow
EndIf
End

I just bought PB, and I find the help a little hard to understand, but this messageboard is SO HELPFUL!
