Rename Column of DataGridView

I want to display a grid with the data from this sql query

SELECT * FROM invoices WHERE ddate >= curdate() - interval 180 day  AND equipment = 1 order by invoice_number desc

I think i have it working, however when i load the form in the program, I get an empty box.

I have attached the entire code

The columns i want are

invoice_number, ddate, company_name, and initials]

If possible, i would like the column names to be

Invoice Number, Date, Company Name and Initials

Just to make sure the connection works, i put a message box with the number of rows it found, and it returns the correct value.

I am just starting to learn vb.net so if the answer could explain as much as possible that would be a big help.
