Hello. First, sorry for me bad english.
I have a problem when i try to update a recorset in visual basic using myvbql.dll.
Well, when i make a select from a table only, i can move my recordset, update, etc... perfectly. But when i try to make a select from 2 or more tables, the consult works perfect: i can move, show all records, etc...
But when i try modify some record, and update it, i get an error message and the recordset DON'T update.
I do something like this:

SELECT DISTINCT tb1.nestudio as nestudio, tb1.nombre as nombre, tb1.suclientes as suclientes, tb2.Nombre as cnombre FROM obras AS tb1 LEFT OUTER JOIN clientes AS tb2 ON tb1.suclientes=tb2.idclientes ORDER BY nestudio

I show it in a form
.......
When something is modified, i do:

MyRS.Fields("nestudio").Value = Me.txtreferencia.Text
MyRS.Fields("nombre").Value = Me.txtnommaq1.Text
MyRS.Fields("cnombre").Value = Me.txtnommaq2.Text
.......
If (MyRS.Update < 1) Then MsgBox "I can't save your changes."

And i can't save the modifications made.

But if i only work with a simple table, everything work perfect.

Please, someone can HELP me?

Thank you.
