I created a simple winform app normally with a form and some comboboxes on it. I have done the same apps for hundreds of times but yesterday, I saw one of the oddest thing and I think that's surely an error in VS 2008 Express Edition IDE. That was I couldn't access any comboboxes (that I had added to the form) in all methods in the region of the form's class. It seemed that "the form didn't have any comboboxes on it". But it could run with some codes I had written before I realized the odd thing. Especially, the codes I had written before didn't have any access to any comboboxes' properties directly by their name but indirectly by the "sender" in some method handling some event of them. Yeah, it worked well, but when I wanted to add some codes using some access to one of properties of the comboboxes, as I said, I couldn't. I thought "Ghosts do it" not myself or anything scientific. Oh my God, I couldn't believe it. After a moment of thinking, I tried adding a new combobox to the form, and I saw it was normally seen as a member of the form, but the old comboboxes were still "hidden" (Ghosts were still doing it)!
Could you please share with me any suggestion on how it can happen? My story is too simple with no need to post any code here. And I think that can rarely happen!
