I'm trying to integrate the calendar view into my application, and everything goes fine until I call the ShowCaptionBar method. At this moment an assert validation fails. I'm adapting my framewnd, doc and view following the Calendar sample, but probably I'm missing something. While debugging, the calendar control object is well constructed, and even the captionbarctrl has hwnd, but it fails when trying to show it (I suppose that the assert validation is related to the size of the control or something like this). I would like to know if there is some method that I should call to initialize the caption bar, or if this object depends on the creation of some other...any help would be appreciated...

Another thing I tried to do is to call ShowCaptionBar at the end of the OnInitialUpdate method of the view of the SQLServer data provider sample, and the assert validation also fails. What am I missing?
