View Full Version : Livevideo "Refresh" after new start!

June 29, 2004, 13:34:39
Hi to all, I am working under LabVIEW and I have a problem with the
"OverlayBitmap property. I am displaying the current system time in the livevideo but when I restart my application,
the old time still appears!
It seems that the time has become a permanent part of the livevideo.
I have found a method called "Refresh" but this one is not explained in the documentation and it has no effect at all!

May anybody give me a hint?

Thanks a lot,

Is it possible, that the system time is saved somewhere in the VI? The overlay bitmap is created new any time an application is started or a new video capture device with new video format and color format has been selected. There is no way to store individual data somewhere in the overlay bitmap.
