Description

Opens a dialog box allowing the user to enter text for searching, for example in a text editor.

As TFindDialog is the parent class for the TReplaceDialog, it contains definitions for the Replace method, but the Replace option does not actually appear when the dialog is displayed: you need to use TReplaceDialog to do that.
