Hi,
That's quite a big question - which subject? what purpose?
Well, the best spot I can think of, to get a good code example, on many fields is Palm's site itself:

goto: http://oasis.palm.com/dev/kb/
then select "Sample Code" from the "1: I want to search articles of type:" option.

This will give you code in lots of fields, from Internet connection to Bitmap manipulation...

If you need code on a more specific field, just ask it, and maybe I'll think of some other source-code site...

Hope this will help,
Offir.

  I had download CodeWarrior for Palm Demo and I downloaded
  sdk40 examples from www.palm.com.
  I try to compail examples in CodeWarrior , but receive
  following errors:

Could not find or load the file "StartupCode.lib" for target "SampleCalc" for project "SampleCalc.mcp".

Error   : the file 'PalmOS.h' cannot be opened
SampleCalc.c line 25   #include <PalmOS.h>   // Includes all Palm headers

Error   : the file 'StringMgr.h' cannot be opened
SampleCalc.c line 27   #include <StringMgr.h>  // Includes all Palm headers

Error   : the file 'FloatMgr.h' cannot be opened
SampleCalc.c line 28   #include <FloatMgr.h> // Include Floating Point headers

  How can I compile this examples?
  May be in CodeWarrior I must define relevant folders?

I don't use CodeWarrior (I prefer GCC with Falch DevStudio) but you probably need to tell CW where the SDK can be found.

Hi,
This error means that the Access path for the project's target isn't set right.
Each target in each project must "know" where the system files are. In our case, it's the PalmOS files for any specific OS version.
Until OS 4.0, (which I really recommend you download from palm's site, and work with! that's the new Palm m505 device OS), the system files folder had the number of the OS version in the folder's name, eg: "C:\Program Files\Metrowerks\CodeWarrior for Palm OS Platform 7.0\Palm OS 3.5 Support". From OS 4.0 and above, the name won't contain the version number, so you won't change all the target's access path for each project you have, but just point them all to "C:\Program Files\Metrowerks\CodeWarrior for Palm OS Platform 7.0\Palm OS Support".

The bottom line is:
1: Open your project.
2: For each target, select "Settings" (the icon just near the target name, or press Alt+F7)
3: Choose "Access Paths" from the left panel.
4: Click on the "System Paths" radio button option.
5: If you got anything there, delete it with the "Remove" button.
6: Click the "Add" button.
7: Search the folder with the OS files, as I've explained before. ("Palm OS Support" on OS 4.0)
8: That's it! :)
close the settings window, save the project and complie again.

Hope this helps,
Offir.
