how can I set a form so that when i open it , it appears with the next
sequential number. I want to set the number pattern and not use
autonumber

Cliff,
Say you have a TblCustomer table with a CustomerNum field. You have a
FrmCustomer based on TblCustomer and the form has a textbox bound to the
CustomerNum field. Put this expression in the Default Value property(Data tab)
of the textbox:
DMax("[CustomerNum]","TblCustomer" )+1
When you enter something in any field in the form and save the record,
CustomerNum will automatically have the next sequential number.

If this is a multi-user environment (or could become one) it is better
to apply the sequence in the Before Insert event.
More than one user could be adding a record with the same CustomerNum.
Besides, the id has no relevance until a record is created.

I assume the form is linked to a table or is adding data to a table . .
so if the table is called tbl_INFO with a key of INFO_KEY (long number )
then you can get the next key number with
NextNumber = Dmax("[INFO_KEY]","tbl_INFO ") + 1
I use this all the time even if the key is set to autonumber . . as it gives
the key to the new record for use elsewhere in any required code.
hope this helps
cheers

The DMax domain aggregate function can be used to get the highest value in a
field in a table, and you can increment that to create the next one. Of
course, you want to be sure you do this only for new records... a little
slipup and you might overwrite existing key fields.

Greetings,
I've been working on a project for my church for a couple of weeks.
We're going to be selling tickets to our events and we need to look
for available seats in our hall.
I have a query that returns to me all the seats that are available,
which is great but the ideal solution would be to return X number of
seats based on a seatnum (Integer).

Hi All:
I know this is simple, but I just can't seem to get there:
I need to sort a table by a text field (txtDescription), then assign
sequential numbers to the field SEQUENCE in table.
Every time a new record is added, the all SEQUENCE #'s must be reset.
The re-numbering will be triggered by an EXPORT button.

this is a slight change to a fequently asked question around here. I
have a table which contains a "sortorder" column where a user can
specify some arbitrary order for records to be displayed in. Users
have sometimes ordered records the way we used to number lines in a
BASIC program (10,20,30, etc.). I'd like to do an update query and fix
this so that every record is in sequential order. I found an example

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
