This typically happens because of one of the following:-
Invalid header - Some applications have used the now non-supported DataFlex MAKE_FILE command to create data files. The data files created by this command are not compatible with the API that our program uses to access data files. If you open the desired file in DFFILE and re-save it without change, this will repair the invalid header.
File read-only - This user on a network has insufficient rights to update a file on a network, or the file is marked read-only on disk.
Overlap fields - These special type fields are supported by DataFlex but by no other system, so sometimes you will get the error "Multi-user conflict - another user changed the record" because this is an untyped binary field and the comparisons always fail. Simply remove the overlap type fields from your query. |
