Do not use RBDB!!!! It is bad IMHO.

If you have problems with classes you can not use,
Look into folder API Way. Here there is no classes!

But IMHO classes simplify coding of applications!
So let's continue to find where you have problems.

WE HAVE 2 such projects. Folder
    Examples/1_x_Examples

You mean Examples/ Classes_way/ BinaryLink ?

Because first is to work with LOCAL disk dbs,
Second to work with remote Valentina Server database.
You can see that they use different parameters.

You can use only first form if you not going to use Vserver.

    wow! This is mistake. Name must be in both.

    actually this is not my example, and I did not polish it.
    I have correct it already.

I think I know where is mistake.

- You mean that you add NEW CLASS into project, right?
- after this you should choose in in project and in the property window
    assign for it parent class to be "VTable"

I think you have not made this, so your class of course do not have property
"Name"

I will check this example

    mDataBase.Open( f )

So what problems? I have not understand...

Okay, this is normal, it helps in debugging.
