UltraLite User's Guide
  Developing Applications for Windows CE

Storing persistent data

The UltraLite database is stored in the Windows CE file system. The default file is \UltraLiteDB\ul_<project>.udb, with project being truncated to eight characters. You can override this choice using the file_name parameter which specifies the full pathname of the file-based persistent store.

The UltraLite runtime carries out no substitutions on the file_name parameter. If a directory has to be created in order for the file name to be valid, the application must ensure that any directories are created before calling db_init.

As an example, you could make use of a flash memory storage card by scanning for storage cards and prefixing a name by the appropriate directory name for the storage card. For example,

file_name = "\\Storage Card\\My Documents\\flash.udb"

Example 

The following sample embedded SQL code sets the file_name parameter:

#undef UL_STORE_PARMS
#define UL_STORE_PARMS UL_TEXT(
   "file_name=\\uldb\\my own name.udb;cache_size=128k" )
...
db_init( &sqlca );
