Windows CE中可用的网络

Question

如何将小型应用程序开发到Windows CE，以使用C＃了解设备中的网络可用性

Answer 1

( i am copying my answer to a similar question here )

Look in the registry key HKLM\\system\\state\\connections , there is are entries for each of the possible network types, for instance:

When connected to a wireless network:

[HKLM\system\state\Connections\Network]
Adapters="BCMSDDHD1"
Count=dword:00000001
Descriptions="Business World"

when connected to activesync:

[HKLM\system\state\Connections\Desktop]
Adapters=""
Count=dword:00000001
Descriptions="CurrentDTPTNetwork"

The Count value under HKLM\\system\\state\\connections gives you the total number of active connections.

In HKLM\\system\\state\\Hardware you can find the current power state of the various devices.
