Reference – article by Andreas Sjöström:
http://www.microsoft.com/mobile/developer/tech
nicalarticles/passthrough.asp
Use ActiveSync 3.7 for Windows Mobile
devices
Personal Area Network
Developer Support
ActiveSync supports
Download / deployment
Debugging
*Tip* Developers can speed up download &
debugging with an ActiveSync network
connection
Emulator
Support ActiveSync
Requires network virtual switch
Refer to eVC++ 4.0 documentation
Local Area Network
ActiveSync
First: establish partnership via direct
connection
Can synchronize over any LAN
Wireless: WiFi (802.11b), 802.11a
Wired: Ethernet, Token-ring
Exchange Server ActiveSync to server
*Tip* Developers can speed up download &
debugging with an ActiveSync network
connection (did I already say that?!?)
Local Area Network
”My Work Network”
Can connect via modem
Virtual Private Network
Need host name –or- IP address
VPN Types:
IPSec/L2TP – need certificate –or- pre-shared key
PPTP – need user name/password
Can have proxy settings
HTTP
WAP
Secure WAP
Local Area Network
What is it good for?
Access to any IP-enabled network service or
server
Fun with HTML
Browse WWW, local web servers
Fun with XML
Web service client
Web service server
Fun with TLAs (three-letter acronyms…)
FTP, SSL, VPN, PPTP
