Combobox1 selects into a cursor. Use that cursor name in the where clause of the select statement in combobox2. In the valid event of combobox1, call the requery method of combobox2. The initial queries are processed after the form load event. They only requery when told to.

My data is in a table called labels with three fields, space, location, and label. I thought my problems were solved but now when I setup my second combo box with the row source set to
select location distinct from labels where labels.space = thisform.combo1.value = labels.space into cursor T2 I get the message "Thisform can only be used within a method"
When I set the row source to
select location distinct from labels where labels.space =combo1.value = labels.space into cursor T2 I get the message "Ali8as Combo1 is not found."
When I put the SQL code in the load or init methods of the form it works without error so the code is okay Is there a different syntax needed here or do I need to handle this in a different way?
Thanks,

Tracy,
I did another test form using days of the week like yours. I still
got
the error. Then I removed the quotes around the CSL statement and it worked! Somewhere in my surfing I had read that the quotes were
required
but that is apparently incorrect.
More details:
- When does the SQL get executed? When it is first loaded? Each
time the control gets focus? When requiry is called? 2. Are all cursors created this way in scope for the entire VFP
system?
- Is there a simple way to see the VFP code generated by the Form
Designer to understand how it works?
Thanks so much,
Joe

Hi Joe,
Those settings are working for me in my quick test. Does the SQL statement you have in the RowSource work in code?
As a test I built a cursor with the days of the week in it in the
Load
event of a form. CREATE CURSOR ComboBoxData (id i, displaytext c(30)) I set the ComboBox.RowSource to select displaytext from comboboxdata into cursor t1 and set the ComboBox.RowSourceType = 3 && SQL statement
To be consistent with your select statement I added the "distinct"
clause
and it still works.
I tested in VFP 9 SP2 Hotfix 3
HTH, Tracy

I want to use an sql select statement as the row source for a combo
box..
- When I set the row source type to 3-SQL and enter the row
source as
"select space distinct from map into cursor T1" attempting to run
the
form results in "Program error Unrecognized command verb"
- If I set the row source type to 2-Alias and the row source to
T1 and
put the SQL select statement into the init method of the control
the
Combo box populates properly.
I would have expected that the system would be smart enough to run
the SQl
statement before trying to use it's output. Is there something else
I
need to call perhaps in the form init method?
Thanks in advance,
Joe
