Using a CPad

Before a UDX can write to or read data from a CPad, it must first:

Define the data type contents of a CPad object.
Define a CPad with a specific name.

You can create a UDX that creates a CPad, writes and manipulates its contents, and returns data all in one function call. Alternatively, you can create several UDXs that do each of those things separately within a single query transaction block.

Note: The following sections contain code samples that you can add to a C++ program. These samples are taken from more complete examples that are shown in Examples of UDXs that use CPads.
