Please suppose I want to design my own text editor . simply like notepad. Without using any richtextbox or other controls LIKE EDIT in C++. Main Handle is just a window in C++ or usercontrol in C#. The Question is here for scrolling option , how can I perform scrolling when user is typing. I mean vertical scrolling here . What is Philosophy of works of scroll bars in C++ windows or C# user controls ?

Should I Clear the (Usercontrol or Window) When User reaches to end of (Usercontrol or Window) and then Put caret on start of (Usercontrol or Window) ?

What about scrolling with thumb or hand scrolling ? How can I find the Text Position which scroll to ?

Dynamic Type to do away with Reflection

as seen on West-Wind - Search for 'West-Wind'
The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
