Call FindField to determine if a specified field component exists in a dataset. FieldName is the name of the field for which to search. If FindField finds a field with a matching name, it returns the TField component for the specified field. Otherwise it returns NULL.FindField is the same as the FieldByName method, except that it returns NULL rather than throwing an exception when the field is not found.
能说说FindField 的一般用途嘛?看来我对他有误区啊,谢谢!
谢谢!我刚才其实也在帮助你找到了,一会给分
