Use the MS-Access COMPANY database available from the course’s web page 2. You must use the ADO.NET Connection/Command/DataReader classes to gain access to the data. 3. Your code must be written using VB.NET and it must use the three EXECUTE modes of the OleDBCommand class (ie. .ExecuteReader, ExecuteScalar, and ExecuteNonQuery). 4. The LOAD button sets the connection object and fills up the GUI with the first employee. a. Show the full name in a textbox b. Show each <Project Name> <Hours> assignment in a single row of the assignment textbox. 5. Make sure your program handles errors / exceptions and does not terminate abruptly. 6. After clicking the ADD button you should create a new assignment for the employee. Use the information in the textboxes to assemble a new WORKS_ON entry. Make sure (a) there is data in those texboxes, (b) the employee is NOT currently working on that project (reject with a message invalid requests). 7. The COUNT button returns (into the appropriate textbox) the number of current assignments. </p>
