Items in a listbox are stored in the Items collection, the help list a SelectedItems to hold the selected items, so in principle your code works, though your li is an object (in general) its 'text' can be gotten calling the ToString()method, so in C# the statement reads:
str += li.ToString() + "\n";
probably in VB you need to use some concat() procedure (I can read, but not write VB).

I hope this is what you searched for.

Try this:

For x as Integer = 0 to ListBox.SelectedItems.Count - 1
str = ListBox.SelectedItems(x).ToString()
Next

Again this will not work because li as ListIem and the datatype of members in SelectedItems are incompatible types.

Correct, as stated I no VB-programmer and simply missed the meaning of the Dim statement. I thought of it as being an object, dimmed thus the code ought to work fine.
