    Exclamation TThreadFunction n Refresh

    Hi All Experts!

    I have created a new RThread in AO.

    When the thread is resumed, it is executing the function wrapped in TThreadFunction.
    While executing that function I want to get the update status on screen.

    Simply I wanna refresh the screen n display the current status of execution.

    I have used CEikLabel for displaying text in my container.

    The screen is getting refreshed automatically twice i.e. when I create the thread in AO(b4 resume) n when the TThreadFunction execution completes(i.e when it comes in RunL of AO)

    My screen is not getting refreshed automatically when the TThreadFunction is getting executed though I call AO refresh function from it.

    But when I press any key its getting updated with the current status.

    Its probably coz I am launching new thread in my app process.

    I have tried all possible options like DrawNow, DrawDeferred, ActivateL ..TRawEvent

    Badly stuck with this issue :-(

    Pls guide.

    Thanks
    Regards,
    Shilpa Kulkarni

    Re: TThreadFunction n Refresh

    Hi Shilpa,

    I am facing the same problem as you, in that i am unable to refresh screen from another thread.

    I am calling DrawNow()/DrawDeferred() from my child thread.I am using a child thread instead of a timer, to call Draw periodically.

    I came across some posts saying updating is not possible, with such an approach.Did you find any solution.If yes can you please share with me.

    I will be happy to hear from you.

    Regards
