Format TextBox with date

I have here a form with several textbox and some combobox. What happens when I insert a code and populate the textbox with birth date appears to me in this 01/01/1900 00:00:00 format and I just want the date to appear.

Can you help me? the names that appear there like DoctorBasic and DoctorEnterpriseDetails are names of tables and the DBO is the column with the dates of birth.

        If e.KeyChar.ToString = ChrW(Keys.Enter) Then ' Enter para pesquisar
            TxtCodigoMed.Focus()
            e.Handled = True
