  1. Module 8: Connecting Network-Enabled Windows CE-Devices

  2. Overview • Windows CE 3.0 Networking • Windows CE Web Clients • Windows CE Web Server • Configuring COM and DCOM • Networking API Support • Support for MSMQ • Support for SNMP

  3. Windows CE 3.0 Networking • New Features • Web Server Support • Distributed Component Object Model (DCOM) • Microsoft Message Queue (MSMQ) • Enhancements • RAS • Simple Network Management Protocol (SNMP) • TCP/IP • Network Driver Interface Specification (NDIS) • DNS/ WINS Name Resolution • Dynamic Host Configuration Protocol (DHCP) • IP Helper APIs

  4. Windows CE Web Clients • Pocket Internet Explorer • IE for Windows CE • Web Browser Control • HTML Viewer Control • Comparing the Web Clients

  5. Pocket Internet Explorer • Supports HTML 3.2: • Tables • GIFs and JPEGs • JavaScript (in PIE 3.0) • Does Not Support: • CSS • DHTML • ActiveX Controls /Embedded Java • VBScript • Memory Footprint =1.3MB

  6. IE for Windows CE • Supports HTML 4.0: • CSS • DHTML • ActiveX Controls and Plug Ins • JavaScript and Java Applets • Tables • GIFs and JPEGs • JavaScript • Does Not Support: • VBScript • Footprint = 3.1MB

  7. Web Browser Control • ActiveX Control • Adds Browsing Capabilities • Requires IE for Windows CE • CoCreateInstance(… • CLSID_WebBrowser • IID_IWebBrowser2

  8. HTML Viewer Control • Supports HTML 3.2 • Used by: • PIE (ver 1.0 and 2.0) • Windows Windows CE Help (PEGHELP.EXE) • Uses the Files: htmlctrl.h, htmlview.lib and htmlview.dll • Uses the APIs InitHTMLControl and CreateWindow(…”DISPLAYCLASS”…) • Does not display images, run JavaScript, or perform any URL processing • Requires a Web browser Control to use it as a web browser

  9. Comparing the Web Clients IE for PIE HTML Viewer Control Windows CE

  10. Windows CE Web Server • CE Web Server Core Features • Web Server Support • Windows 2000 Web Server • Windows CE Web Server • MinComm Web Server • MaxAll Web Server

  11. Windows CE Web Server Core Features • Active Server Pages (ASP) • Scripting Support • Internet Server API (ISAPI)

  12. Web Server Support Windows 2000 Windows CE • HTML, ASP, • ISAPI • MTS, Certificate Server, Index Server, MSMQ, • Windows Media – Webcasting, Active Streaming • Database Connectivity • Active Directory • HTML, ASP • ISAPI
