ImagePro>Re: disappearing mouse

["Tarachandani, Anil" <anil_tarachandani[at]merck.com>]

Hello Scott Reed and Kevin Ryan:

Thanks for your suggestions. Regarding 1) The crashing excel issue, my macro
has exactly the same code as Kevin Ryan's excel macro with the "set xlapp =
nothing" as the last line. This problem happens inspite of having that line.
My only question is : Is there a macro command to explicitly stop the macro
- equivalent of pressing the red square "stop" macro command in the macro
editor. Once I stop the macro (unload?) then excel communications work
wonderfully.

For 2) the video card drivers: this problem happens with ImagePro only -
Other screen intensive applications for video capture/VGA overlays do not
show this problem. Though I do understand that to replicate it would require
some pretty intense testing. Also, another observation. If I use a PC remote
controlling program like VNC (http://www.uk.research.att.com/vnc/) then I
can actually see the mouse logging in from another computer and can still
work the computer.

Thanks.

Anil

Anil,

1. Make sure you are setting your object to nothing at the end of the macro
(Set xlapp = Nothing). Additionally, you may want to explicitly Exit your
macro when it has completed it's job. There are multiple ways to accomplish
this, you'll have to find the best way to suit your needs.

2. A disappearing mouse-pointer is a common problem after performing video
intensive (or Resource Intensive) work on your computer. There are literally
thousands
of articles on the topic and most point towards video card drivers. I
suggest
starting with video card drivers and settings before making changes to your
registry
(as many sites suggest).

Hello:

I am using ImagePro 4.5.0.22 with Windows NT and analyzing images. I export
data using OLE to Excel using a very similar macro to the demo-macro from
Kevin Ryan published in this newsgroup,16 May, 2001.


However, there are two issues which are irritating.

1. My macro typically processes a directory and after it is done it stops.
If I close Excel immediately after that - Excel crashes. But if I hit the
"stop" button on the macro and then close Excel then all is well. Is there a
command to make the macro "stop" so I dont have to manually "stop" after
each run?

2. After the macro has been used to process files (~2000-3000 files) or half
a day worth of processing, the mouse cursor dissappears. The computer has
NOT crashed. If I move the mouse (which I cannot see on the screen) I can
find menu items and click them. I can select items using the keyboard but it
requires a restart to see the mouse again. This happens at random intervals
after ImagePro has been used to process data but usually happens after
processing more than ~2000 files. (Task-manager does not show anything
unusual - no process running after the macro is done and no excessive use of
memory).

This reminds me of a similar problem that I had during colocalization when
my macro became a square - this apparently will be fixed in future versions
by Yuri Gaidoukevitch at Media cybernetics.

What can I do ?

Thanks.

Anil
