DESQview API (advanced programming interface)
The DESQview API is described in the Version 2.0 manual on page
193 under the heading "A DESQview-specific program...".
Using the API, your program can access the features of DESQview
from the system level. This can allow your program to spawn new
tasks, pass information to other windows and control the size and
shape of windows. One window can be made a subtask of another.
It is also possible using API to exercize full control over the
system so that your program becomes in effect the front end menu
of the system with DESQview providing windowing, memory
management and multitasking under the surface.
Quarterdeck plans to provide a programmers reference to the API
during the latter part of '87. Until that time, there are
several other references available:
"Appendix J - DESQview Version 2.0 manual"
Appendix J contains general programming information regarding
interfacing programs to DESQview including Assembler source code
for several of the most basic DESQview calls. For programmers
that simply want to make their programs run very well in DESQview
while retaining the ability to run in DOS outside of the DESQview
environment, this selection of calls provides all that most
programmers will ever need. It is important to note that these
calls are also supported by earlier versions of DESQview. More
advanced API calls may require the use of DESQview 2.0 or above.
DESQview Bulletin Board System:
Some source and object code files for implementation of the basic
calls is available from the DESQview Bulletin Board System. Full
access to the BBS is restricted to users with priority service or
users with registered, serial-numbered copies of DESQview.
The Quarterdeck Bulletin Board system operates 24 hours a day,
seven days a week. The telephone number is (213)396-3904.
Supported baud rates are 2400/1200/300. Preferred communications
parameters are: 8 data bits, No Parity, 1 stop bit. You should
plan to download using one of the following error-free protocols:
XMODEM, XMODEM CRC, YMODEM or KERMIT.
Books:
"The Programmer's Guide to TopView", by Alan R. Miller. Published
by SYBEX, 2344 6th. St., Berkeley, CA 94710 (415)848-8233.
Price: about $19.95. Available at many computer book stores.
Gives an overview and introduction to the API. Includes source
code examples (in Assembler) of many of the API functions. Does
not include any disks and is not really a substitute for an API
Toolkit or reference manual. However, since the cost is
reasonable, this is an excellent source to discover the
possibilities of programming under the API.
Programming Toolkits:
TopView Programmer's ToolKit Version 1.10 by I.B.M. Corp.
Source: International Business Machines Corp.
P.O. Box 1328-W
Boca Raton, FL 33429-1328
The definitive source of API information until the DESQview API
Toolkit becomes available. Contains Assembler and IBM Pascal
source code and full API documentation. Developers making
extensive use of the API should probably consider obtaining the
TopView Toolkit. Approximate cost: $395.
TopView Toolbasket version 1.01 by Strawberry Software Inc.
Source: Strawberry Software, Inc.
42 Pleasant Street
Watertown, MA 02172
(617)923-8800
Contains documentation and Lattice libraries on disk for 71 API
functions. Designed for use with the Lattice "C" compiler.
Approximate cost $190.
Bulletin Board Users: If you would like to receive notification
of the release of the DESQview API, leave a message with your
name and mailing address in the <C>omments section of this
bulletin board and we'll put you on the list. SYSOP
