i have a bunch of listboxes one has the final item you select then press addtocart witch will take seprate parts of the string and add themm to the relevent listbox and have qty set to 1 what i want is if the same item is selected again is instead of making a dublicate is to increse the relevent qty in the qty listbox but i keep getting this error

 

Public member 'Items' on type 'String' not found

 

 

i know i could use a listview for this task instead but i wanted to do it with seprate listboxes any help would be appreciated thanks

Step 1 is to use a debugger and figure out on which line the error is occurring. I'm going to guess it's this line:

Dim tempqty As Integer = Integer.Parse(lstQuantity.SelectedItem.Items.text)

Assuming the ListBox contains only strings, lstQuantity.SelectedItem is a string, which does not have a public member named Items.

 

This problem could probably have been avoided if you enabled Option Strict. I'm not going to go on a long rant about why it's bad to not use Option Strict, because there are already a million billion of those on the internet. All I'll say on the subject is that Option Strict is there for the sole reason of preventing errors.
