Storing SQL results via Recordset in a text box

Hello,
I am currently building a form where I need to store the results of an SQL into a text box.
The results will be a one field query, where it will display the Customer names. The bit I am stuck on is not the SQL, but to go through the results and assigning it to a textbox.
Will I need to do a for loop and assign to an array? If so, I will need some assistance with the coding. Thanks in advance!
