Description: How to encode/decode the string? I consider that the database may be open by other software when I operate the database, so I want to know whether I can encode the database in other ways, that is to say, even though others can utilize other software to open the database, they will see some rubbish and do not know the content of the database at all. Under the circumstances, I write the following method for encoding/decoding utilizing the function RND ( ) which is contained by the VB. When the parameter of RND ( ) (we call it seed) is negative, the same seed produce the same random sequence, at the same time, VB have powerful function of binary technique. Then we can encode/decode the string in the following way.
