comments: error code: reference to a non-shared member requires an object.

comments: pastries.Price is underlined. pastries.productionCost is underlined.

dgvDisplay.DataSource = pastryQuery.ToList dgvDisplay.Columns("Id").HeaderText = "Item Id" dgvDisplay.Columns("Description").HeaderText = "Item Description" dgvDisplay.Columns("Profit").HeaderText = "sellingPrice-productionCost" dgvDisplay.Columns("Price").HeaderText = "Selling Price" End Sub End Class

Load Event: Populate the String array from the Pastries.txt file using the ReadAllLines method then... Set a size for the structure array, pastries (using ReDim) then... Populate the structure array, pastries from the String array using a For loop. First Button Click Event: This event must use a LINQ to order the pastry items from the structure array, pastries into alphabetical order based on the Item Description. The output should include all six fields for all records in the file. The query results should be displayed in a DataGridView control. Columns should be given meaningful header text. Second Button Click Event: This event must use a LINQ to order the pastry items from the structure array, pastries into descending Selling Price order then Item Description ascending order. The profit for each pastry must be calculated (selling price - cost to produce). The output should include the profit along with Item Id, Item Description, and Selling Price. The query results should be displayed in a DataGridView control. Columns should be given meaningful header text.
