It's nice to know someone else's mind works like mine does. I have no
answers for you, but if memory serves me, I believe in the old DOS Oasis,
when you created a database, the manual recommended you enter 2 users for
the database, you and the computer. I suspect superuser is related to this
somehow but don't quote me. Meanwhile, I'm having my own troubles. Perhaps
you or anyone else out there can help me. Below is a portion of my GX code.
I have one channel, called 's' that I loaded into hVVs. hVVs is declared as
a REAL VV. In the for loop, I set hVVt, that I previously created and also
delcared as a REAL VV, to a math expression involving hVVs. For testing
purposes, I simply set hVVt to 3.0. When I run the GX, I know it run's
through completely becuase I get to the 'DONE' message at the end. If the
channel 't' previously existed, nothing in the channel changes. If I then
run another GX, such as refid.gx, upon completion of the refid gx, channel
't' is suddenly filled with 3.0 's. I've been messing around with locking
and unlocking hChant in different permutations but I can't figure out the
problem.
iVVlength = iLength_VV(hVVs);
for (i=1; i<=iVVlength; i++)
SetReal_VV(hVVt, i, 3.0);
if (iExistSymb_DB(hDB, "t", DB_SYMB_CHAN) == 0)
hChant = CreateSymb_DB(hDB, "t", DB_SYMB_CHAN, DB_OWN_SHARED,
DB_CATEGORY_CHAN_FLOAT);
else
hChant = FindSymb_DB(hDB, "t", DB_SYMB_CHAN);
LockSymb_DB(hDB, hChant, DB_LOCK_READWRITE, DB_WAIT_INFINITY);
PutChanVV_DB(hDB,hLine,hChant,hVVt);
UnLockSymb_DB(hDB, hChant);
Abort_SYS("DONE");
}
