Answer 1

If you set the ValueMember here:

CmbConAcc.ValueMember = "ACCOUNT_CODE"

why would you expect to get anything other than that out?

The ValueMember is the name of a property/column of the data source. When the user makes a selection, the value from that property/column of the SelectedItem is exposed by the SelectedValue property. That's what you need to use.

That's what the code example in the documentation for the ValueMember property demonstrates and that's why you should ALWAYS read the documentation. VS has a Help menu for a reason.
