My X51 shuts down from my program for no apparent reason

CDurbin · 02-13-06, 11:06 AM

I have 5 programs that run as a package on the Axim. We use them for route sales and invoicing in the beverage industry in 4 states, entering orders, printing invoices via BT, and transmitting data back and forth using cell phones, infared, CF modems, BT modems, and Activesync. Due to the size of the programs, I had memory issues. To fix that, I put all source code and data on SD Cards (and rewrote a lot of code for efficiencies and memory usage). My problem is that on occasion, for no apparent reason, the program seems to dissappear. The screen is still on the program, but when you tap on an event, the program goes to the start screen. No messages, no nothing. When I check the "running programs" under Memory, the programs are gone.

This is a semmingly random event. Anyone else had this problem?
(BTW the code adds up to 266 pages of VB.net code between the 5 progams so I probaly should not post it. :) )
I have been runnning the code on the Axim for a couple of years now. Though I did have to change the code (WM5.0, VB.Net8.0) it is still the same basic flow and code that had worked fine.

Your program crashed. Talk to whoever wrote it.

I wrote the program, and I agree with you. However, there was no "screen of death" or any error messaging what so ever. Strange behaviour. It acts like the program lost connection with the device. How do you trap that to see if it is the case?

No screen of death because you were lucky and your program crashed but it did not crash the axim. You will have to write some logging in your app to figure out why it crashed. Only when it crashes it probably can not write a log. Least you will know what it did last.

Might investigate wm5 logging and how to turn it on. I have made some small effort to write programs for wm5 but have not actually done it yet. I have not really seen any good (free/cheap) tools and Microsoft seems to have the deal locked up with certificates.

CDurbin, we have a Developers Corner forum that might be of some help to you.

BTW, welcome to Aximsite!

Maybe he could benefit from the SD disappearing fix.

I am trying that on 7 of my devices. I suspect that the problem is related to the SD Card.
