Solution 1

rm_no is most likely not the same object as the one you have in the list box.
Thus the object you are trying to remove is not present in the listbox item set.

Take a look at your CheckedListBox.Items collection:

Think about what it means that this a collection of objects.

Examine the methods exposed by this collection: which two of the methods will remove an Item, and what do they require as arguments in order to remove a specific item ?

Yeah, it's probably a bit puzzling: how do you take something like a string, and make it usable as an 'object' : figure that out and you have your answer.

How do you convert any type of .NET object to another type ? Clearly understand that and you will have answered at least 1000 questions you will face in the future ... or, your money back :)

good luck, Bill
