Thanx John..
Would you mind give me an example about the Form Error Event that you had told me..?
I think editing record is more complex than inserting data...
Regards
Hendra

Hendra-
Partly correct. Leave record-level locking turned on.
Here's what will happen when two users try to change the same record:
1) User A will find the record and start to edit it. This sets a timestamp locally.
2) User B will find the same record, edit it, and save. The save sets a timestamp of the time of the save.
3) User A (who went to get a cup of coffee after starting to edit) tries to save.
Result: Access will see that someone else has updated the record since A started to edit. User A will get a warning message with an option to either discard the changes A just tried to make or copy the changes to the clipboard. User A *cannot* overwrite what B just did. You can use the Form_Error event to trap this case and issue a custom message that forces the user to start over.

Thanx John...
No Lock setting (is setted on the form ...right?)... is that the same way to unchek "Open Database using record locking"..?
Then if we set all of the form properties to "No Lock", what will happen if more than one users edit the same record in the same time..?..(i can't imagine it)

Hendra-
Unless you have dozens of simultaneous users, the chance of a "collision" editing records is very very low. As long as you have No Locks set, you should have no problems with bound forms.
Important notes:
1) Users should NOT try to share a database over a wireless connection.
2) Users should share only the "data" database on a server - a database with the tables only. Each user should have his or her own copy of the "code" database (linked tables to the shared data, queries, forms, reports, and code).

Thanx John...
Yes..that is what i am thinking...why do we choose the harder way if Access give the simpler way.?..
But the other side i am thinking to about the table's burden (..is the word "burden" right?..sorry if not)..
I mean with the bound form, users are access directly to table at the same time (especially with UPDATE processing)..
so with that opinion i think unbound form is better because it's not access the table directly and no connection to the table happened
until we run the INSERT or UPDATE command.
But in several articles i've read that sometimes Inserting or Updating with codes give slowly processing especially in wireless connection..
Please give me more explanation because i am developing my first multi user application,,so i have to decide the best methods from beginning
Regards
Hendra

Hendra-
If you use unbound forms, you are putting into code what Access will do for you.
Your application will be much more complex and more time-consuming to build.
There is a small advantage to using unbound forms, but a bound form will provide
very satisfactory results, especially if you set Record Locking to No Locks.

Hi All,...
Which is more better in network environment and multi user :
Bound Form (Data Entry : Yes) Or Unbound Form (Insert Into method) ?
