Hello, I am trying to bind a specific column to a specific control. The problem is that when the combo box control appears blank when I try to bind a column to this control, but if I bind the column to a text box, then it displays the correct value of that column. pbndtemp = New Binding("Text", ds, "schedule_detail.Expr1") Me.cboTrainingProgress.DataBindings.Add(pbndtemp) pbndtemp = New Binding("Text", ds, "schedule_detail.Expr1") Me.txtProgress.DataBindings.Add(pbndtemp) Do I need to evaluate or validate the combo box binding? If so, how do I do that? Thanks, Jay Feng Screwed... the art of moving to a new place because the old place is just too messy and not worth the effort to clean.

SELECT MINHello, Is there a way to select a row from a table based on a minimum? Or what is the correct syntax? This query returns two rows when I only need a row with the min column... :( select min(col1ID), col2ID, col3 from tbl where col2ID = 'xxxx' group by col2ID, col3 Thanks, jay

Multiple columnsHello, Please advise on how I might be able to make this sproc work... declare @TrainerID int select TrainerID, LastName, FirstName, City, State, Country, r.code, l.description, p.Code from trainers as t inner join Regions as r on t.region = r.regionid inner join Languages as l on t.Language1 = l.LangID --and t.Language2 = l.LangID --and t.Language3 = l.LangID inner join products as p on t.product1 = p.ProductID --on t.product2 = p.ProductID --on t.product3 = p.ProductID --on t.product4 = p.ProductID where TrainerID = @TrainerID The situation is that I have designed in the Trainers (t) table multiple columns of Languages and Products with properties as Int which stores values based on their respective LanguageID and ProductID from the Languages and Products (definition) table. The dilemma is on the result, I would like to see the actual codes and not the ID key of each of the multiple columns coming from the definition tables.

VB.NET ListboxesUrgent - HELP!!!!!!!!!!!!!! How do I populate three (3) different listboxes in a single form - programmatically (vb.net)? I really do not want to use the visual tools. The items of the listboxes are coming from the database. I can connect to the database and can query the database to the specific tables, but my dilemma is that I can't seem to populate the listboxes. Do I need to instantiate three different sqladapters and datasets after I connect to the database? Afterwards, how do I map or bind the results to the specific controls. Please provide a simple code. Thanks. Jay (Lost in Self-strangulation)
