Re: Creating Databases Dynamically
I just finished doing this. I originally started by using a database of database names, but then realized it wasnt needed. My app only requires one DB open at any time. To let the user pick which one to open, I dynamically fill a List with the names of DBs by seraching for them by creator ID and type with DmGetNextDatabaseByTypeCreator. I felt this is better that the first idea because if something happens to the Database of Database names, then all those Databases will be sitting on the palm and not have any way to get to them. As per the Palm Companion document, I 'behind the scenes' add and remove - with being my creator ID, to the end of each DB name (the name is user set) to make them unique. The user only sees the name that they typed in, but the actual name of the DB is Users name - CRID -Mike Carl Smith [EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED] Dave- Thanks for the great suggestions, I forgot about the number 2 way.

Creating Databases Dynamically
Does anyone know of or have suggestions on the possibility of creating DBs dynamically? In other words I want to create a database(s) as the application is running. The application would start with one or two static dbs but as the user needs I would like to create other dbs, depending on the user's input. Thanks in advance Carl -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/tech/support/forums/

This function creates a database: Err DmCreateDatabase (UInt cardNo, CharPtr nameP, ULong creator, ULong type, Boolean resDB) Where: cardNo is the card where the that will be created nameP is the name of the database(up to 31 characters) creator is the creator id. type is the type. resDB if true, will create a resourse database.
