Answer 1

You would need to execute a non-query method which returns:
For UPDATE, INSERT, and DELETE statements, the return value is the
number of rows affected by the command. For all other types of
statements, the return value is -1. If a rollback occurs, the return
value is also -1.
Microsoft documentation -> Here
Which is as simple as:
Dim ID : ID = Form2.txtID.Text
Dim Age : Age = Form2.txtAge.Text
Dim Sex : Sex = Form2.txtSex.Text
Dim FN : FN = Form2.txtFullName.Text
Dim command As New OleDbCommand("UPDATE YOUR_TABLE_NAME SET _
FullName = '" & FN & "',_
Age = '" & Age & "',_
Sex = '" & Sex & "'_
WHERE ID = '" & ID & "'", Connection)
command.ExecuteNonQuery()
