of the document

7. The following key combinations can be used to carry out tasks with an embedded
Excel application:
Ctrl+; Insert the date in the current cell
Alt+= Sum continuous column of numbers containing the current cell
Ctrl+Z Undo the last operation
Shift+F3 Invoke the Function Wizard
F7 Check spelling
8. The standard prefix for the name of an OLE container control is ole.
9. OLE replaces an earlier technology known as Dynamic Data Exchange (DDE)
that was used to integrate applications into Visual Basic programs. DDE is
slower and more difficult to use than OLE.
13.2 ACCESSING THE INTERNET WITH VISUAL BASIC
■ WHAT IS THE INTERNET?
The Internet began in the late 1960s as a plan to link computers at scientific laboratories across
the country so that researchers could share computer resources. This plan was funded by the
Defense Department’s Advanced Research Projects Agency (ARPA) and initially was known
as ARPANET. Over time, many research institutions and universities connected to this network.
Eventually, the National Science Foundation took over ARPANET and ultimately it became
what we now know as the Internet. The past few years has seen an amazing amount of growth
in this global network. It more than doubles in size every 6 months.
The Internet often is confused with one of its most popular components, the World Wide
Web (WWW) or “the Web.” The Internet is much more than the Web. It also consists of electronic
mail (e-mail), file transfer (FTP), news groups, and remote login capabilities. E-mail
allows people to send messages to one another over the Internet. FTP allows people to transfer
files from one machine to another. This is often the preferred method of retrieving shareware
or freeware programs over the Internet. Usenet is a large collection of electronic
discussion groups called newsgroups. There are newsgroups dedicated to every topic imaginable.
People can post messages that all members of the group can read and answer.
The World Wide Web is made up of documents called pages, which contain pictures and
text. The pages are accessed through programs called browsers. The best known Web
browsers are Netscape, Mosaic, Lynx, and Internet Explorer. Web pages usually include links
to other pages. These links are often set apart from the regular text by using boldface, underlining,
or color. When you click on a link, you call up the page referred to by that link. This
technology for connecting documents is called hypertext.
