You have mixed versions of Windows CE.
Pocket PC 2005 is basd on Windows CE 5.0.
The code sample you downloaded is for Pocket PC 2003 which is based on
Windows CE 4.2.
So the code sample expects CE 4.2 libraries and code.

Make sure you have downloaded "Windows Mobile Developer Resource
Kit.msi". (It's hard to miss as it is ~800 MB). I would suggest
installing everything in the Resource Kit.

Throw away that old project and create a new project in VS2005 (now
that you have installed the Dev Kit and restarted VS2005).
Here are some project instructions to help you get started:
----------------------------------------------------------------------------------
1. New Project
2. Visual C++ -> Smart Device -> ATL Smart Device Project
3. MyPpcProject (for example)
4. Include the "Pocket PC 2005" project.
5. OK.

VS2005 will generate a project for you.

6. Right-click the project "MyPpcProject" in the "Solution Explorer"
view.
7. C/C++ -> Preprocessor -> Preprocessor Definitions : add
_WIN32_WCE=$(CEVER);UNDER_CE;$(PLATFORMDEFINES);WINCE;
8. C/C++ -> General -> Additional Include Directories : add
"C:\WMSDK\WMPSDK10\include;" (the directory where you installed the WMP
10 SDK)
9. Linker -> Input -> Additional Dependencies : add "Strmiids.lib
Ws2.lib" (I forget what these are for; if your project compiles then
remove them one at a time)
10. Linker -> Advanced -> Target Machine : set to "MachineTHUMB"
11. Linker -> Command Line -> Additional Options : add
"/subsystem:windowsce,5.01"
12. Cross your fingers and try compiling!
----------------------------------------------------------------------------------
You may need additional tweaks to your project configuration.
It's hard to predict the relationships between code for WMP 10, CE 5.0,
and PPC 2005 get confusing.
I can't remember why I added some of the above entries to my project so
some of them may be superfluous.


A great way to explore and learn is to see how configuration changes
affect the calls to the compiler and linker.
Or, said another way, all those configuration changes in the GUI simply
amount to a different environment and command line passed to the
compiler and linker.
1. C/C++ -> Command Line
2. Linker -> Command Line
3. Tools -> Visual Studio 2005 Command Prompt
cl /?
link /?
