  97 FindReplaceDialog is a standard modeless dialog which is used to allow the user
  98 to search for some text (and possibly replace it with something else). The actual
  99 searching is supposed to be done in the owner window which is the parent of this
 100 dialog. Note that it means that unlike for the other standard dialogs this one
 101 <u>must have a parent window</u>. Also note that there is no way to use this
 102 dialog in a modal way; <b>it is always, by design and implementation, modeless</b>.
 103
 104 FileReplaceDialog requires the use of <b>FindReplaceData</b>. This holds the
 105 data for the dialog. It is used to initialize the dialog with the default values
 106 and will keep the last values from the dialog when it is closed. It is also
 107 updated each time a FindDialogEvent is generated so instead of using the
 108 FindDialogEvent methods you can also directly query this object. <b>Care must be
 109 taken not to use this object after the dialog is destroyed.</b> The data within
 110 will be invalid after the parent dialog is destroyed.
