Home Utility Auditing Program Week Four

Objective:
Create a single form Home Utility Audit Program using Visual Studio Desktop 2013, VB.Net. I have most of it except the * parts in specific requirements

Specific requirements:
The user should be able to do the following: Pick an Appliance from a list(combo box) of appliances - *from text file using an array* 
Enter the cost per kilowatt-hour. - *defaults from text file, these should correspond with appliances, using an array* 
Enter the power needed in kilowatts 
Enter the number of hours used per day for the selected appliance. 
A running total 
A listing area ( I used a DataGrid) that displays the appliance, hours, and daily cost. 
All must have validation(I have but not the best) and no message box only labels can be used for errors.
