Destroying a Caret

When a window loses the keyboard focus, the system sends the WM_KILLFOCUS message to the window. Your application should destroy the caret while processing this message by using the DestroyCaret function. The following code shows how to destroy a caret in a window that no longer has the keyboard focus.

case WM_KILLFOCUS: 
 
// The window is losing the keyboard focus, so destroy the caret. 
 
    DestroyCaret(); 
 
    break;
