hi all,
i am having a table emp

in that i have 4records like
a1, a2,a3, a4.
i had created a form ,using the above table.
in tht the provision is if i enter the empno,
all the other fields should be retrieved.
i had a problem when i am accessing the same record (let it be a2) from the same form but from two different terminals .Imean to say
i had opened the form in the designer mode, and in the runform i will entry the a2 record's emp no and will
retrieve the data.
the same form i will open from other terminal ,
and will enter the a2 record's empno ,
then itz displaying the error as
Could not reserve record(2 tries)

and prompts for YES or NO
if YES then it displays
Could not reserve record(4 tries)
keep trying

hi,
this is a common problem for which there are many answers but not necessarily solutions! The database throws this type of error when there are two sessions tryin gto access the same record because these two sessions (people) might want to update the same record which is not feasible. Violates dbase constraints.
