[.net] PDA Capturing battery temperature data.
Author
Hi there, I hope this is suitable here. I've got a Dell Axim 51v. I've been using a program called wr_Resinfo and on the advanced tab it displays the battery temperature.
I'm trying to make my own little application is visual studio 2005, in a smart device project. Is there anyway I can capture the battery temperature data? I've seen a number of applications like the one stated above doing it so I'm sure its possible.
- Any help would be appreiated.
A simple google search gave me this:

and

The SYSTEM_POWER_STATUS_EX2 structure holds a BatteryTemperature field.
Just to note: I searched for "wince battery temperature". I find that when I preceed all my search queries with "wince" I usually get programming related topics.

Actually I thought all was well, though it's not working. I found some examples posted on the internet tried to put it together with a timer and a text box, it deploys fine I get no errors, all I see in the text box is zero. The sensor is working, I'm still using wr_Resinfo to monitor it. Yet I'm unable to obtain it.
I've also tried TextBox1.Text = PowerStatus.BatteryTemperature.ToString
Any ideas why its just showing zero?
