- ===============
- 1: MAPI Sample
- ===============
- Program example using the MSMAPI.VBX controls, MapiMessages and
- MapiSession controls.
-
- Note: To run this sample, you need a MAPI-compliant messaging
- system such as the one contained in Microsoft Windows for
- Workgroups.
-
- BRIEF DESCRIPTION:
- This sample program illustrates the use of the MAPI controls by
- sending and receiving electronic mail.
-
- BACKGROUND:
- The MapiSession control establishes a MAPI session and signs off
- from a MAPI session. The MapiMessages 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.
- MAILLST.FRX.......The binary portion of the mail messages form.
- MAILOPTF.FRM......Form for setting options.
- MAILSUP.BAS.......Module of support routines for the example.
- MSGVIEW.FRM.......Form in which a viewed message is displayed.
- MSGVIEW.FRX.......The binary portion of the viewed messages form.
- NEWMSG.FRM........Form for creating a new message.
- VBMAIL.FRM........The main form.
- VBMAIL.FRX........The binary portion of the main form.
- VBMAIL.MAK........The MAKE file for the project.
-
- TO RUN:
- After starting the Visual Basic environment (VB.EXE), you can load
- files in this sample program by choosing Open Project from the File
- menu and select the VBMAIL.MAK file.
-
-
- =====================
- 2: Multimedia Sample
- =====================
- This sample program illustrates the use of some of the device types
- supported by the Media Control Interface (MCI). The four device
- types used in this program are:
-
- Device Type Description
- ----------- -----------
- MMMovie Plays Multimedia movie files (*.MMM).
- 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:
- In order 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
- ----------- --------
- MMMovie No extra hardware. *See software requirements.
- CDAudio CD-ROM drive.
- Sequencer Sound card (e.g., Sound Blaster Pro)
- WaveAudio Sound card.
-
- SOFTWARE REQUIREMENTS:
- In order to run the MCI application, Microsoft Windows with
- Multimedia Extensions 1.0, or Windows with Multimedia must be
- installed. The Multimedia Extensions include device drivers for
- the different types of MCI devices.
-
- 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
- ----------- -------------
- MMMovie MCIMMP.DRV *See note below.
- 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 4 of the above device types were installed:
-
- [mci]
- CDAudio=mcicda.drv
- WaveAudio=mciwave.drv
- Sequencer=mciseq.drv
- MMMovie=mcimmp.drv
-
- BACKGROUND:
- The 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 MCI control is also smart enough to know 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.
-
- MMMovie NOTE:
- If you are unable to run an animation movie (*.MMM file), make
- sure the MCIMMP.DRV and MMP.DLL files are installed on your
- machine. To install the animation driver from Windows 3.1, run
- the "Drivers" applet from the Control Panel, insert Disk 1 of the
- Professional Edition. Select "Unlisted Driver," and accept "A:\"
- as the directory. You will then be ready to use the animation
- features of the MCI control.
-

- server
- 11. Support of Access, Dbase 3, Dbase 4, FoxPro 2.0, Paradox
- 3.x, Btrieve, SQL and Oracle data, both DDL and DML.
-
- The code contains comments to help explain the use of the various
- methods in the data access layer. Code and forms may be copied from
- this application to other applications with minimal modification.
-
- ODBC BACKGROUND:
- ODBC (Open DataBase Connectivity) is a standard adopted by
- multiple vendors designed to enable users to connect to any data
- source with a single application. This is achieved through a
- layered approach including:
- 1. Programming Layer-embedded functions in the development
- tool which in this case is Visual Basic Professional.
- 2. Driver Manager-the basic ODBC library that routes calls
- to the appropriate driver.
- 3. Data Driver - the library of functions that acts upon a
- specific database backend such as SQL Server, Xbase,
- Excel, etc. (note that SQL Server is the first of many
- drivers to become available for ODBC)
- These layers work together to enable data access from any source
- for which an ODBC driver exists. The sample application will work,
- without modification, on any new level one ODBC driver that becomes
- available. With multiple drivers, connections may be made to
- different data sources from the same application at the same time
- enabling seamless data access from disparate data sources.
-

-
- TO RUN:
- After starting the Visual Basic environment (VB.EXE), you can
- load files in this sample program by choosing Open Project from
- the File menu and select the VISDATA.MAK file in the
- SAMPLES\VISDATA directory.
-
- If you want to open a local database, you simply need to choose
- the type of database and a file open common dialog will be
- provided with the file type set to the requested data file type.
-
- If you choose ODBC from the File/Open menu, the next dialog you
- will see is the Open DataBase form. Since you probably have no
- servers entered, you will need to enter a name for an existing
- SQL server on your network. If you already know the user ID and
- password, you can add them as well. The Database name is optional.
- Once you have entered this data, select 'Okay' and you should be
- able to log on to the server. You may get some more dialogs in
- the process. Answer any questions you can and ask the SQL
- administrator for help if you run into problems or don't know some
- of the parameters.
-
- Once a database is open, a simple double click on a table name
- will open the table in the selected mode (Single Record or Table
- View). Use the Query Builder to create dynasets with selected
- data from one or more tables at a time. If "Use Data Control" or
- "Use Grid" is chosen, a dynaset will be created. However, the
- following objects will be created under the following circumstances
- when the "No Data Control" option is selected:
-
- Data Type: Feature Chosen: Object Type Created:
- ------------------------------------------------------
- MS Access Table Open Table
- MS Access Query Open Dynaset
- MS Access Execute SQL Dynaset
- ISAM Table Open Table
- ISAM Execute SQL Dynaset
- ODBC Any Dynaset
-
- The table is always updatable and dynaset will be updatable in
- most cases except on ODBC with no unique index, certain multiple
- table joins and other SQL select statements such as count(*),
- max(), etc.
