After calling camEx.FocusAndTakePicture (or TakePicture right away), the picturetaken event is called with the byte contents of the photo. This works without any problem.
However, if you put your mobile phone on the table and try to take a "black" picture, picturetaken is *not* called. Would it be possible to add some kind of error trapping here? A "picturenottaken" event? Or an "error" event? I would like to notify the users their picture was not taken, but that does not seem to be possible right now.
