set printername very slow

edited June 2008 in General
hi,
I?ve noticed that setting printer by printersetup.printername:='MyPrinter'
is very slow.
Tracing into the code reveals that the API-function DeviceCapabilities slow
down on each call.
version 10.7
on version 7.04 we used before this functionality seams to be much more
effective ..

any suggestion how solve this problem ?
thanks
Andy

    Try testing with different printers. If you have a slow network, then it
    will be slow. If you have a local printer it will be so fast will not notice
    it. That code has not changed since RB 7.x. RB is optimized to cache the
    results, so it only has to make the call one time.

    FTR: I just had MS Word lock up for ~30 seconds due to a remote printer that
    it could not access.

    It's an OS issue, and, IMHO, is embarrasing to MS.

    Just a quick note to say that we have noticed downgrade in performance
    between RB 7.x and RB 10 but we haven't been able to pin it down yet. We
    have also been in contact with Digital Metaphors and were hoping that the
    performance changes in RB 10.08 would have solved our problem but sadly it
    didn't. It actually got worse...
    I know that saying that there is a problem without giving Nard & Co the
    necessary test cases and information to fix it is not really helpful. I am
    just saying that if you Andreas can somehow get some sample code which will
    in the same printer environment show a definite difference between RB 7 and
    RB 10 than it might solve both our problems. The test case which we sent to
    DM was probably not conclusive enough and we haven't really had the time to
    put together another one. But since the problem is still there I guess we
    will soon have to find the time to do so.

    Regards,
    Kjell

    Best way to test is with a profiling tool, such as AQTime. Setup a test case
    with the /exact/ same environment. Same machine, same printer, same
    everything - such that the only difference is RB 7/RB10. Typically what
    happens is that customers upgrade and change other factors as well.

    FTR... when I do this, I typically setup two paths to to different versions
    of a component--and don't have either installed on the palette. I create all
    my components at run time (with reports, they could be loaded from a file).
    This way I only have to change the path and can ben quickly running the
    second version.Also, makes it easy for any support team to quickly compare
    the versions.
