Be careful not to overwrite additional global attributes previously defined by yourself or a device. Synchronized realms are located by URLs. For this, we need a layout file and Adapter class. Notices Welcome to LinuxQuestions. Configuring a Realm Configure a Realm before opening it by creating an instance of Realm.
This means that all non-optional properties must have a default value.
There are three exceptions to this: Although TClientDataSet has no built-in database access mechanism, you can connect it to another, external, dataset from which it fetches data and to which it sends updates. For fetching user data, you may have to create a form wherein user can add multiple entries and submit them simultaneously.
The framework is responsible for managing how synchronized Realms are cached or stored on disk. Jul 03, · This thread is locked. You can follow the question or vote as helpful, but you cannot reply to this thread.
