Multi-access required on a dbase table

Hi,

l wrote a simple program in c++ builder 3.0 with Dbase IV tables. The software works perfectly, now l have a need to run this software on two(2) different computers accessing the same Dbase tables.

Software on Computer A uses Dbase tables on its local drive
Software on Computer B uses Dbase tables on Computer A

When reading the Dbase tables from both computers it works, however when trying to write l get records missing and overlapping.

l tried to lock the Dbase table using Table1->LockTable(1); however it did not work. Also when l modify a record on Computer A, Computer B records did not update do l need to some how refresh the Table?

There is no server only two (2) stand alone computers connected together.

Any ideas or examples would be appreciated.

Thanking you in advance
Elias
