ECOVRWRT is a file in the Microsoft Software Library that demonstrates how an application can implement a multiline edit control in which the user can toggle between "insert" mode and "overwrite" mode. In insert mode, new text pushes any existing text further to the right. In overwrite mode, new text replaces any existing text.

To implement overwrite mode, ECOVRWRT subclasses the multiline edit control. When the control is in overwrite mode, when the control receives a WM_CHAR message, the character after the selection point is selected and replaced with the character in the wParam of the message.
