Hello,

we are working on an ATS which uses signals of a neural network to
pass to the TWS via ActiveX using VB. The application runs stable on a
Win2000 and a Win XP computer (testet with several hundred trades in
the demo mode), but on a Win98 computer there seems to be a momory
leak (or whatever else). After about 10 trades the whole system will
slow down and halt, but after using ctrl+alt+del the program fine for
the next 10 Trades. But another application reports a shortage of
memory. Looking a the used memory, there doesn't seem to be an
increase. All computers are equipped with 256 MB of memory.

Has anybody else experienced such a problem??? (I know that it is
better to run the application on a Win NT based System, but there
might be a general problem with our program

thanks for your help

Bernhard

I've run tests on a Win98 machine with VB ActiveX to the TWS and
haven't noticed the problems you mention. Are you doing a lot of
object creation and destruction in your code or graphical calls to
the API where you aren't freeing up the resources after use? Win98 /
95 in general don't free up resources very well in my experience.
Something else might be doing lots of redim preserves especially with
UDTs?
