Many Palm OS applications have a corresponding application on the desktop. To share data between the device's application and the desktop's application, you must write a conduit . A conduit synchronizes data between the application on the desktop and the application on the hand-held device. To write a conduit, you use the Conduit SDK, which provides its own documentation. Input Methods Handheld users don't have a keyboard or mouse.
Users enter data into the device using a pen.
While Graffiti strokes and the keyboard dialog are useful ways of entering data, they are not as convenient as using the full-sized desktop computer with its keyboard and mouse. Therefore, you should not require users to enter a lot of data on the device itself. It is intended as a satellite viewer for corresponding desktop applications. If your application needs to perform a computationally intensive task, you should implement that task in the desktop application instead of the device application. Memory The Palm OS device has limited heap space and storage space.
