data base errors -- 1.x documentation

[Jennifer Hall]

sorry, but I cannot find any reference to a IsOPen call for the data
base?????

could you point me to where this is in the documentation???

I currently have the V4MD_Reference_1_en.pdf, ValentinaKernel_1_en.pdf, and
ValentinaSQL_1_en.pdf. None of which even mention the open data base
command. so I must be missing some documentation.

thanks
Jennifer

But this is not correct test.
You try open for the same pDB object!
So second open for the same object do nothing in v1.
In v2, we are more strict and return error "already opened"
In v1 you can test db IsOpen


-----
But as I understand, you want feature -- when SEVERAL .exe files
Will try open the same db files. Right ?

To test this you need produce 2 EXE file and test to see how this works.

Or you can do 

   openDatabase(pDB, dbpath, 4)
    err = ValentinaError()

   openDatabase(pDB2, dbpath, 4)
    err = ValentinaError()

I.e. Use 2 different db objects pdb and pdb2
