[AccessD] Need help with a combobox issue

Turn the SQL for the combo box into a Union Query.  Like this:

SELECT EmployeeID, EmployeeName FROM tblEmployees WHERE
CurrentlyEmployed=True

UNION SELECT EmployeeID, EmployeeName FROM tblEmployees WHERE
EmployeeID=Forms![frmTempData]![EmployeeNumber]

That way, the top SELECT displays all normal employees, and the bottom
select includes the one possible employee that may not meet the criteria in
the top SQL.  To fully implement, however, you will need to requery the
combo box in the OnCurrent event of the form, so that as you move from one
record to another, the 'current' employee is added to the combo as
applicable.  This will temporarily put the employee into the combobox's list
for that record.

Subject: [AccessD] Need help with a combobox issue


Hi All,

I have a combobox that is bound to a field. The field stores the employee
number that is associated with the current record. The data for the combobox
is pulled from a table and the combobox is set to limit to list. The list is
made up of two columns, one for the employee number (bound column) and
another to display the employee's name. The employee number column is set to
0" so that only the employees name is visible. Because employees come and
go, I have added the ability to edit which employees are shown in the
combobox list. This allows the addition and removal of new and old employees
respectively.

At the time a record is created the associated employee would have been in
the combobox list because they would be an active employee. Some time after
the creation of this record the employee may leave the company and would be
remove from the list of the combobox but the record would still reference
the terminated employee. If someone were to go back and look at this record,
it would display nothing because the employee is not in the list. I added
some code that checks to see if the Text property of the combobox is an
empty string and if so look up the name of the terminated employee and set
the combobox's Text property accordingly. The problem with this is that it
generates a NotInList error and you are forced to undo the change in order
to move on.

Any ideas on how to work around this. I would like to keep the ability to
modify the list of active employees so that users do not waste time weeding
through old employees while allowing the combobox to display the employee
name of someone who is no longer with the company.

Any help will be greatly appreciated!

Thanks
JR
