I cannot find how to display an error message when what I typed in the listbox field is not in the listbox collection.
For example the listbox contains the following items
1) Apple
2) Strawberry
3) Mango
If for example I type "Mongo" and then press tab to another field, a message will pop up saying I typed something not in the listbox. Anyone who knows how to code if text in textbox1 is not in listbox then blah blah blah.

I have a functioning program that has been completed that based on miles and gallons used, both will display the individual MPG for each single entry as well as compile a total for the miles, gallons used and overall MPG at the bottom.My problem is that when 0 is entered for fuel, the MPG calculation says Infinity and 0 is placed in the gallonsUsedListBox.I've been trying to get the statement "Gallons must be greater than zero" into thegallonsUsedTextBox by utilizing an If..Then statement but to no avail. I'm not sure where to input it or if my avenue of using the If..Then statement is even on track. Here is the code I have:

I keep getting the error shown in the screenshot below.To me it's saying that I haven't established the "UpdateCommand" property for the DataAdapter. However,I have established it as well as the "SelectCommand", "InsertCommand" and "DeleteCommand".All of these are created within a Class Module.I created a Class for the "tblControl" table that is is referencing. This class contains all the properties for this table as well as calls for "inserting", "updating", "selecting" and "deleting" records.I have attached a class.vb file so their is a clearer understanding. The highlighted line of code below is where I'm receiving this error message.[code].....
I'm receiving this message while trying to add a NEW client record as well as a NEW client Address record to the database. This portion works fine.
