Hi -

My Windows form needs to have a dropdown displaying values from a table in database.

Here is the sql I need:  strSql = "SELECT CodeNbr, CodeValue FROM Code WHERE (TableName = 'Test') AND (DeleteInd <> 1)"

What control do I use to create a dropdown? And how?

Thanks for your help!

Go to your toolbox and drag a combobox onto your form.
Click on the combobox where the little triangle is and select "Use databound Items"
Click on the datasource dropdown and a wizard will open, select database.
Select a connection or click new Connection and fill out the server and database you want.
Select Yes save the connection string.
According to your sql your table would be Code? That doesnt look correct. So select the proper table from the list. Click Finish.
Back on the combobox tasks, click Add query.
If you dont know sql, use the query builder and select the fields you want, CodeNbr, CodeValue ? If you know sql enter your query in the box.
Back on the combobox tasks select your display member, either CodeNbr or CodeValue. Whichever one you want to appear in the dropdown.
Then select your value member.
Again on the combobox click Preview Data, then Preview. If you setup your sql right you will see the query return the data. If you didnt then you may have selected the wrong server, database, you dont have access rights, the server isnt running, etc.

Thats about it. Basically the wizard will walk you thru it. If you follow the wizard you will be fine.
