I am beginner is WinAPI. I have an editor control (window with class "Edit"). I need to track all changes in it. That is I need know what and where was added or removed. For example, in WPF I can get this information through event TextChanged of TextBox. Is it possible via standard functions of Windows API?
Windows will send your parent window an EN_CHANGE notification message when text in the edit control changes. It's up to you to work out what changed - the system doesn't do that for you automatically.
