The following list shows the registry values that control system power state transitions for the sample Power Manager:

• ACUserIdle
• ACSystemIdle
• ACSuspend
• BattUserIdle
• BattSystemIdle
• BattSuspend
• BatteryPoll

These DWORD values are stored in the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\Timeouts registry key. A value of 0 indicates that no time-out will occur. The sample implementation does not provide a method for bypassing OS power states; however, OEMs may choose to do so.

For the Power Manager to actively manage system power states, these settings need to be present in the registry. The actual decision to manage system power is based on the presence of ACUserIdle.

Note   To prevent conflicts between GWES and the Power Manager, you need to disable GWES power management as described previously. When the Power Manager is actively managing system power, it may restrict applications from entering arbitrary system power states.

You can reset the system state transition timers by creating a named auto-reset event called _T(« PowerManager/ReloadActivityTimeouts« ) and calling SetEvent on the handle of that event. This informs the Power Manager to read transition timer settings again from the Timeouts registry key.

GetSystemPowerStatusEx

This function retrieves the power status of the system. The status indicates whether the system is running on AC or DC power, whether or not the batteries are currently charging, and the remaining life of main and backup batteries.

BOOL GetSystemPowerStatusEx(
PSYSTEM_POWER_STATUS_EX pstatus,
BOOL fUpdate );

Parameters

pstatus
[out] Pointer to the SYSTEM_POWER_STATUS_EX structure receiving the power status information.

fUpdate
[in] If this Boolean is set to TRUE, GetSystemPowerStatusEx gets the latest information from the device driver, otherwise it retrieves cached information that may be out-of-date by several seconds.
Return Values
This function returns TRUE if successful; otherwise, it returns FALSE.

Remarks
The GetSystemPowerStatusEx function is not supported for emulation.

Sur le PPC, le nom de dossier "My documents" dépends de la langue de version de ROM. Voici la méthode d’eVC pour récupérer ce chemin: [Ref : MSDN]
SHGetSpecialFolderPath(NULL,szTxt,CSIDL_PERSONAL,0);

CSIDL_PERSONAL requests that the "My Documents" folder be returned in szTxt (TCHAR).
