Add features to a custom text control in C++ and MFC

The attached code is for a custom edit control built in Visual Studio 2003. It allows for text entry via the keyboard. It supports the backspace key to delete characters. The purpose of this control is to provide similar functionality to the CEdit control except with custom drawing routines. This control only supports a single line of text. Please enhance this control to provide these features: 1) Provide cursor adjustment through the text using the left and right arrow keys. 2) Allow selection of characters like you see in Microsoft Word, Notepad, or the standard edit control in Windows. Show the selected characters using a different font color and different background color from the main text. You should be able to select characters using the mouse or Shift + left or right arrows. 3) Provide initial selection of all text when left clicking in the field. 4) Provide replacement of characters by typing when other characters are selected. For example, you select the entire range and then type T. The previous text is replaced with T. 5) Provide deletion of characters by pressing the Delete key with an active selection.
