Is there a limit to the number of cells which can be held in a grid
with Windows CE?

I can get at least 450000 with Win32 but only 350000 with WinCE, after
which the program shutsdown without warning or messages.

I don't know if this is a limitation of the hardware or programming
language.

Regards

There is no limit in the language, but I guess there is a limit in the
amount of memory you can use on the device

There s plenty of memory (288MB). WM 6.5 limits memory to 32MB per
application, but this is still plenty - data =2MB when programs crash.
It is definitely limited by the number of cells - increase data size
and decrease number of cells prevents crash. However, I need up to
500000 cells for the programs to be of any value.

Ever tried with KGrid? http://www.tkweb.eu/en/delphicomp/kgrid.html
It seems to have a virtual mode where the data is not stored in the
grid itself.

I don't know if this works on WinCE but you could try it.
