HANDLE hDbase,
CEOID oidRecord,
WORD cPropID,
CEPROPVAL * rgPropVal );
You need to fill the CEPROPVAL structure with the properties that its table is going to contain. This is akin to assigning data types to columns in a standard Access or SQL database. Table A outlines the legal data types.

Our application stores the following properties in the CEDB database as shown in the following list:
- strTitle--256-character Unicode string
- nHour--short int
- nMinute--short int
- nRating--float
- strDescription--1,024-character Unicode string
HANDLE hDbase,
DWORD dwFlags,
LPWORD lpcPropID,
CEPROPID * rgPropID,
LPBYTE * lplpBuffer,
LPDWORD lpcbBuffer,
HANDLE hHeap );
Closing the database You close the database by unmounting the volume that the database is located on. The function CeUnmountDBVol helps accomplish that, as shown in the following code: BOOL CeUnmountDBVol (
PCEGUID pceguid );
Conclusion You now have the foundation and code to write a simple, quick database application using Windows CE. In the next installment, I will cover an ADOCE client application that hits SQL Server via a wireless connection located on a corporate backbone.
