How to check if all the items are selected in a Listbox

[snjpverma]

I want a Listbox to be launched when I click the Option button. I am using the below code for that.

I have placed the Listbox in a different userform (I hope this is an elegant method). This Userform contains only the Listbox, so the below code for launching the form/Listbox.

Private Sub Optionbutton1_Click()
HintForm.Show
End Sub

However, the option button shouldn't get marked unless all the values in listbox are marked as "Yes". The moment all the values are checkmarked, the listbox/userform unloads and the Option button gets selected.
How do I check if all the items are selected in a Listbox?

Please advise the code for the same.

Anyone on this one?
In post 1 , I meant to say that all the items are selected, by mistake I wrote "items marked as "Yes".
