May anyone can teach me how to assign a autonumber, I want to create a
number that is starting with year(auto change to year 2006) +
autonumber (eg. 2005-0001, 2005-0002)

Have two separate fields one with DateCreated defaulting to Now() and a
second for RecordID. Even if you don't think you need the record creation
date down to the second that could change down the road and you will be set
if it does. In in the mean time it is an easy way to get the year that you
want. With two fields it is easier to calculate the next ordinal number and
it is easy to display them on your forms and reports in the format you want
with...
=Format(DateCre ated, "yyyy-") & Format(RecordID , "0000")
To assign the RecordID as each record is created use the following in the
form's BeforeUpdate event.
If IsNull(Me.Recor dID) = True Then
Me.RecordID = Nz(DMax("Record ID", "TabelName" "Year(DateCreat ed) =
Year(Date())"), 0) + 1
End If
The above finds the highest existing RecordID value in the table created in
the same year as the current year and then adds 1 to it. The Nz() covers
the very first record of each new year and the If-Then block is necessary
because BeforeUpdate can fire more than once for a given record. This IS
the event you want to use though because it is the only one where the record
is saved immediately after assigning the new value.

Thank you Brandt. I have tried your suggestion, when I input in FORM -
PROPERTY - FORMAT the followings : "=Format(DateCr eated,
"yyyy-")........, it will turn to
("=F"\m"at)d"at "ec\re"at"ed",y yyy-)&f"\rm"at(R"ec o\rd\ID",0000)"
Please tell me what's wrong with this?

Rick wasn't suggesting you put that in the Format property. You put the
formula he gave into the text box's ControlSource property.

Apple,
What I do is keep a one row table with a column for each seperate sequence
number I need. If I only need one then it's only a one row, one column
table. I store the last sequence number used in that table then run an
update statement to iterate that number each time I need the next number.
This way more than one copy of the application can be runing and get the
next sequence number as needed.

Thank you Doug, I had tried to put the formula into FORM-TEXT
BOX-CONTROL SOURCE PROPERTY or FORM-UNBOUNDED TEST BOX-CONTROL SOURCE
PROPERTY, but it show error(#xxxx?); when I tried to put into a query
as an expression, when open up the query or form, it will ask to enter
an parameter (1) date; (2) number, if I entre (1) 2005/01/01; (2)
0001, it will show 2005-0001 in all record that I have input data
before.
The following is in my form's BeforeUpdate event :
Private Sub RecordID_Before Update(Cancel As Integer)
If IsNull(Me.Recor dID) = True Then
Me.RecordID = Nz(DMax("Record ID", "FORM
NAME""Year(Date Created)=Year(D ate())"), 0) + 1
End If
End Sub
