Definition
property AutoExpand: Longlnt;
Description
AutoExpand property tells the component if the data buffer can be expanded when it is too short for the data that needs to be written to it. The value gives to AutoExpand is the number of bytes that are append at the end of buffer. It default to 256 bytes. If you plan to append lots of data, you should consider making AutoExpand value much larger. If you know how much data to have to add, you could make AutoExpand slightly larger (because of delimiters and escaped characters). If you make AutoExpand to small, then performance is low because there will be a lot of memory reallocation. If you make it to large, memory will be wasted.
