See battery status

[Arnaldo Fuziy]

With your help, we've got to this function that is returning perfectly the
battery status (just translated from C# function sent by Alex Feinman). Is
there any way that we can see backup battery status (that one in the power
app in control panel)?

There are several "BackupBattery..." members in what you posted. Are they
not providing what you need?

-Chris

 

[Arnaldo Fuziy]

Unfortunately not, they all return zero...

Tks,

Arnaldo.

 

[Chris Tacke, eMVP]

If they return zero, then the device doesn't support the values.

I don't have any devices that use backup batteries, but the OEM of the
device is responsible for implementing the information about backup battery
status. What device is this? Does the Power Control Panel applet display a
backup battery status?

[Arnaldo Fuziy]

In my equipment, when I enter Control Panel, and look in Battery info, there
are two batteries: Main and "reserve"... I'd like the status of the reserve
battery...

Tks,

 

[Paul G. Tobey [eMVP]]

It seems like it should be possible, then. What sort of information is
given for the reserve battery? What device are we talking about?

Are

As with your MemoryStatus calls, you cannot use Long. Use Integer.

It returns 0 for the reserve batteries... The device is an iPaq 2210...

Yes, your API declaration is wrong.

I guess what I'm asking is what does the Control Panel show for the reserve
battery? A percentage? Good/Low/Very Low?
