如何把其他对象的OBJECTID保存到扩展词典的扩展记录中

LoveArx

The appended code does this exactly. Please note that we have to convert object ID to ads name when we set the result buffer to the xrecord, and vise versa when we retrieve the result buffer. Please also make sure that we pass a reference to the first resbuf in the linked list to the setFromRbChain() function instead of the resbuf pointer.
