menu or press Ctrl+F. To invoke the Replace dialog box, choose Search | Replace from the
menu or press Ctrl+R. Figure 10.12 shows the C++Builder Replace dialog box. With a couple
of obvious exceptions, the Find dialog box contains the same options.

dialog box.
For the most part, the options on the Find and Replace dialog boxes do exactly what they
indicate. If you choose the Case sensitive option, you need to type in the search text exactly
as it appears in the source file.
The Whole words only option requires a word of explanation. C++ code is, obviously, not
plain text. Take the following line, for instance:
Memo->Caption = GetCaption();
In this case neither Memo, Caption, nor GetCaption could be considered a whole word because
they are surrounded by special C++ syntax characters. If you search for the word Memo and have
the Whole words only option on, the Find operation will ignore syntax characters and will
still find Memo in this line.
The Regular expressions option requires explanation as well. When this option is on, you can
use special wildcard characters when doing searches. For a complete description of the
wildcard characters, see the C++Builder online help under the topic Regular Expressions.
When replacing text, it is safest to leave on the Prompt on replace option. When you do a
Replace All operation with this option on, the editor highlights each found word and prompts
you whether to replace it. It is easy to miscalculate the results of a Replace All operation, so
always use Replace with care. Even then, it still pays to remember that maxim: “Undo is your
friend.”
The rest of the Find and Replace options are self-explanatory and therefore don’t need
additional mention.
