I'm a newbie Palm developer.
I am writing an application that needs to store two distinct types of
records. I want to keep one of these record types sorted by index in the
database. I assume that this implies that I need to create two databases.
In my AppStart method, I call DmCreateDatabase twice, but when I tap on
info, I see that only the database named in the last call seems to be shown
in my list of installed applications and database. The code looks like
this:
//attempt to open first database, if it doesn't exist, create a new one
firstDatabase = DmOpenDatabaseByTypeCreator(dbOneType, appFileCreator,
dmModeReadWrite | dmModeShowSecret);
if(! firstDatabase)
{
DmCreateDatabase(0, DbOneName, appFileCreator, dbOneType, false);
binkDb = DmOpenDatabaseByTypeCreator(dbOneType, appFileCreator,
dmModeReadWrite | dmModeShowSecret);
}
//attempt to open secod database, if it doesn't exist, crate a new one
secondDatabase = DmOpenDatabaseByTypeCreator(dbTwoType, appFileCreator,
dmModeReadWrite | dmModeShowSecret);
if(! secondDatabase)
{
DmCreateDatabase(0, dbTwoName, appFileCreator, dbTwoType,false);
tranDb = DmOpenDatabaseByTypeCreator(dbTwoType, appFileCreator,
dmModeReadWrite | dmModeShowSecret);
}
So my question comes in 2 parts:
1) Do I need two databases to keep two sorted collections of disparate
records, or is there some preffered way of maintaining this information in a
single database?
2) If I do need two databases, how do I create the second one?
