Remebered the first Flash tutorial I saw was to morph/transform a rectangle into a circle. But This simple task cannot be done in Expression Blend 1.
Now with Expression Blend 2 preview, it is possible. This feature is called “Vertex Animation”.
Wait, I actually morphed a circle to rectangle, by converting circle into path on key frame 1 and editing the path to rectangle on key frame 2. It is not exactly same as the “Tweening: shape, Blend: Angular ” in Flash
How about morph text?
How about doing things like in the beginning Flash tutorials?
MFC is the C++ wrapper to Windows API. It was a great help when moving from DOS to Windows where the Windows API required a new mind set.
Now it’s WPF age, WFP/XAML is another big mind set change. Acropolis came to help this time. Its wizard askes something like “Do you want SDI or MDI?” and “Do you want menu bar, tool bar and status bar?”. They are famous questions in MFC wizard.
