Note:  Some of the sample applications use conditional compilation to make
calls to 16-bit and 32-bit APIs.  If you are using the 16-bit version of Visual 
Basic in a 32-bit operating environment, the sample applications will still 
make calls to 16-bit APIs.

========================================
1:  MAPI Sample Application (VBMAIL.MAK)
========================================

This sample program demonstrates the use of the MAPI controls by 
sending and receiving electronic mail.  It uses the messaging application 
programming interface (MAPI) controls: MAPI messages and MAPI session.


Note:  To run this sample, you need a MAPI-compliant messaging
       system such as the one contained in Microsoft Windows for
       Workgroups.

BACKGROUND:
The MAPI session control establishes a MAPI session and signs off
from a MAPI session.  The MAPI messages control allows you to 
perform a variety of messaging systems functions after a messaging 
session has been established.  These functions include accessing, 
downloading, and sending messages, displaying the details and 
address book dialog boxes, accessing data attachments, resolving 
recipient names during addressing, and performing compose, reply, 
reply-all, forward, and deleting actions on messages.

FILES:
   MAILLST.FRM.......Form for displaying the list of mail messages.
   MAILOPTF.FRM......Form for setting options.
   MAILSUP.BAS.......Module of support procedures for the example.
   MSGVIEW.FRM.......Form in which a viewed message is displayed.
   NEWMSG.FRM........Form for creating a new message.
   VBMAIL.FRM........The main form.
   VBMAIL.MAK........The project file for this sample application.

TO RUN:
From the Visual Basic File menu, choose Open Project and 
select the VBMAIL.MAK file, which is listed in the
\SAMPLES\MAPI subdirectory of the main Visual Basic directory.
Press F5 or choose Start from the Run menu to run the application.

===================================================
2:  Multimedia MCI Sample Application (MCITEST.MAK)
===================================================

This sample program demonstrates the use of some of the device types
supported by the Media Control Interface (MCI).  The three device 
types used in this program are listed in the following table.

Device type     Description
-----------     -----------
CDAudio         Plays audio discs from the CD-ROM drive.
Sequencer       Plays MIDI sequencer sound files (*.MID).
WaveAudio       Plays digitized waveform sound files (*.WAV).

HARDWARE REQUIREMENTS:
To access a CD-ROM drive or a sound card, the hardware,
along with any supporting device drivers, should be installed
and configured for the machine.  The following table lists
the hardware required for the MCI device types used in this
program.

Device type     Hardware
-----------     --------
CDAudio         CD-ROM drive.
Sequencer       Sound card (for instance, Sound Blaster Pro (TM))
WaveAudio       Sound card.

SOFTWARE REQUIREMENTS:
For the multimedia MCI control to work, MCI services must be present.
These services are provided in the Microsoft Windows operating system 
version 3.1. 

To access a specific MCI device type, the corresponding MCI device
driver must be installed.  The following table lists the device 
drivers required for the MCI device types used in this program.

Device type     Device driver
-----------     -------------
CDAudio         MCICDA.DRV
Sequencer       MCISEQ.DRV
WaveAudio       MCIWAVE.DRV

The [mci] section of the SYSTEM.INI file contains a list of the
installed MCI device types.  This is what your file would look
like if all three of the above device types were installed:

[mci]
CDAudio=mcicda.drv
WaveAudio=mciwave.drv
Sequencer=mciseq.drv

BACKGROUND:
The multimedia MCI control provides a high-level interface for using 
multimedia devices. Using the property settings of a control, you
can determine the settings and the actions of a device.

The multimedia MCI control can also recognize what actions are 
relevant for the current state of a device.  For example, if you 
click a "Pause" button while playing a movie, the "Play" button 
is automatically re-enabled.

FILES:
   ABOUTBOX.FRM.......Form for the About box.
   ABOUTBOX.FRX.......The binary portion of the About box form.

   WAVE.FRM...........Form for playing waveform and MIDI files.

TO RUN:
From the Visual Basic File menu, choose Open Project and 
select the MCITEST.MAK file, which is listed in the
\SAMPLES\MCI subdirectory of the main Visual Basic directory.
Press F5 or choose Start from the Run menu to run the application.

==========================================
3:  Outline Sample Application (PHONE.MAK)
==========================================

This sample program demonstrates the use of the Outline control 
with an address book database application.

5:  VisData (VISDATA.MAK)
=========================

This sample program demonstrates various programming techniques
used to access data through the Data Access Object (DAO) layer
built into the Visual Basic, Professional Edition.  

Note:  To access ODBC data sources with this sample you must
       first install ODBC using the ODBC setup program provided
       with Visual Basic, Professional Edition.

VisData behaves like a general purpose database utility 
capable of the following functions:

       1. Database and table creation.
       2. Table modification (adding and deleting fields and indexes).
       3. Data browsing/modifying using the three recordset types.
          (table, dynaset, and snapshot) and three form types
          (single record, data control, and data grid).
       4. Property browsing on all objects.
       5. Form demonstrating the new data-bound list and 
          data-bound combo box controls.
       6. Import/export to all supported data types.
       7. Direct SQL statement execution for any SQL supported
          functions such as Insert, Update, Delete, Drop, Create,
          Dump, and so forth.
       8. AdHoc Query builder that helps users unfamiliar with SQL
          create complex queries with Where clauses, Joins, Order
          By, and Group By expressions while limiting output to
          selected columns.
       9. Transaction processing.
      10. Copying table structures and data to same or different database.
      11. Support of Jet MDB, Dbase III and IV, FoxPro 2.x, Paradox 
          3.x and 4.x, Btrieve, Text, Excel, and SQL Server both DDL and DML.
