DDEExecute( ) Correction
------------------------------------------------------------------------

The syntax for DDEExecute( ) is incorrect on page L3-363 of the Language
Reference manual and in the help file.  The correct syntax is:

    DDEExecute(<expN>, <expC1>[, <expC2>])

where <expC2> is the name of a user-defined function (UDF).  There is
no format parameter in this command.

------------------------------------------------------------------------
Question 1

What is the easiest way to install FoxPro on a network?

Answer 1

In a network environment you must first install FoxPro on the server and
then set up each workstation.  Installation on the server is called an
Administrative Setup (/A).  This option decompresses all FoxPro for
Windows files and Setup files.  FoxPro for Windows files will be read-
only on the network drive.

To perform an Administrative Setup, Choose Run... from the Windows
Program Manager File menu.  When the Run dialog appears, type
a:\SETUP /A or b:\SETUP /A (depending on the floppy drive you are using)
in the Command Line box.  Press Enter and proceed with the installation.
You will be prompted for your user information and an installation
directory, default drive, path name, etc.  For more detailed information
refer to the Instructions for Administrative Setup in the Installation
and Configuration guide for FoxPro for Windows.

Installation on individual workstations is called Workstation Setup (/N)
and requires a previous Administrative Setup.  The Workstation Setup
copies FoxPro initialization files, updates some common .DLL files, and
creates a Program Manager group and an icon on each workstation to run a
shared network version of FoxPro for Windows.

The workstation setup may be performed in two ways: from the network or
from disk.  To install from a network drive, open the Windows File
Manager and then open a window with the correct network path for FoxPro
for Windows and double-click on SETUP.EXE.  Choose the Workstation
Installation button in the Installation Type dialog.  To install from
disk, type a:\SETUP /N or b:\SETUP /N in the Run dialog Command Line
box, then press Enter.  For more detailed information refer to the
Instructions for Workstation Setup in the Installation and Configuration
guide for FoxPro for Windows.
------------------------------------------------------------------------
Question 2

What kind of "rights" do I need to install FoxPro on the network?

Answer 2

You will need full system rights to install on the network.  Contact
your system administrator for further information about your specific
installation.
------------------------------------------------------------------------
Question 3

Why are workstation users on our network unable to use the graphing and
spelling-checker features in FoxPro?

Answer 3

Workstation users need access to the MSGRAPH and PROOF subdirectories in
order to use these features.  Contact your system administrator
regarding user access to these subdirectories.
------------------------------------------------------------------------
Question 4

During installation I was asked to select either DOS-style keystrokes or
Windows-style keystrokes.  Which should I choose?

Answer 4

If you are not sure which style to use, select Windows-style keystrokes.
Windows-style keystrokes correspond to standard Windows keystrokes.
DOS-style keystrokes let FoxPro for Windows behave like FoxPro for
MS-DOS.  Later, if you want to use DOS-style keystrokes, add the line
KEYCOMP=DOS to your CONFIG.FPW files.  For more information about the
styles of keystrokes, see the SET KEYCOMP TO command in the FoxPro
Language Reference manual or online help.
------------------------------------------------------------------------
Question 5

What is the minimum files setting for FoxPro for Windows?

Answer 5

The minimum FILES setting is 40.  During installation, Setup checks your
CONFIG.SYS file.  If your FILES setting is less than 40, a dialog gives
you three choices: have Setup make the modifications for you, have Setup
make the modifications after you have reviewed and edited the changes,
or allow you to make the modifications later.  If you allow Setup to
modify your CONFIG.SYS, your old file is saved as CONFIG.OLD or CONFIG.001
if CONFIG.OLD already exists.  For more information, see the chapter on
Customizing FoxPro in the Installation and Configuration guide.
------------------------------------------------------------------------
Question 6

Does FoxPro for Windows update any Dynamic Link Libraries (DLLs) in the
Windows subdirectory where system files are kept?

Answer 6

Yes.  The following DLLs are updated:  COMMDLG.DLL, DDEML.DLL, OLECLI.
DLL, OLESVR.DLL, SHELL.DLL, TOOLHELP.DLL and VER.DLL.

The FoxPro graphing capabilities require that these two files be stored
in the Windows subdirectory \MSAPPS\MSGRAPH: GRAPH.EXE and GRAPH.HLP

FoxPro spelling-checking capabilities require that these three files be
stored in the Windows subdirectory \MSAPPS\PROOF: MSSPELL.DLL,
MSSP_AM.LEX, and MSSP_BR.LEX
------------------------------------------------------------------------
Question 7

I accidentally deleted some of the FoxPro sample files.  Can I reinstall
these files without reinstalling FoxPro?

Answer 7

Yes.  Run Setup again and select the Custom Installation option from the
Installation Type dialog.  This option lets you choose which components
to install.
------------------------------------------------------------------------
Question 8

I am having difficulty reading the FoxPro disks because of an alignment
problem with my floppy drives.  Is there another option for installation?

Answer 8

Try copying all the files to a directory on your hard disk and then
install from the hard drive.
------------------------------------------------------------------------
Question 9

I'm trying to install FoxPro for Windows under Windows 3.0 and I'm
getting the message "Cannot write VER.DLL."  Any suggestions?

Answer 9

Rename the VER.DLL file in the Windows System subdirectory.
------------------------------------------------------------------------
Question 10

I'm having difficulty installing FoxPro.  I've tried streamlining both
my CONFIG.SYS and AUTOEXEC.BAT and I still can't install
FoxPro for Windows.

Answer 10

First of all, don't try to install from within a replacement shell
(Norton, etc.).  Second, make certain you have disabled all TSRs,
including anti-virus software.  Check the WIN.INI file for the LOAD= and
RUN= lines.  Comment these lines out using a semicolon (;).
------------------------------------------------------------------------
Question 11

Can I put a common WIN.INI file up on the server?

Answer 11

No.  Each workstation has its own WIN.INI file.
------------------------------------------------------------------------
Question 12

What is the best way to edit the WIN.INI file?

Answer 12

The WIN.INI file may be edited with Notepad or EDIT.EXE in MS-DOS 5.0.
------------------------------------------------------------------------
Question 13
If I modify my WIN.INI file, is it advisable to restart Windows?

Answer 13

Yes. As a general rule, always restart Windows when you have modified
the WIN.INI file.  There are some exceptions, but if you are trouble-
shooting you want to be certain that all changes are reflected in the
current environment.
------------------------------------------------------------------------
Question 14

Can I delete the directory named ~msstfqf.t?

Answer 14

Yes.  The directory named ~msstfqf.t is created during setup.  Ordinarily
this directory is deleted at the end of the installation process.  This
directory may be deleted.
------------------------------------------------------------------------
Question 15

I get the error message "Insufficient Memory" when trying to load FoxPro
for Windows.  What setting needs to be modified?

Answer 15

Add a MEMLIMIT statement to your CONFIG.FPW file.  The syntax for this
statement is MEMLIMIT=%,min,max where % is a calculated amount based on
available memory and min and max represent actual minimum and maximum
allocations.

For example, specifying MEMLIMIT=80,1024,4096 allocates 80 percent of
your system's available memory to FoxPro with a minimum allocation of
1024K and a maximum of 4096K.
------------------------------------------------------------------------
Question 16

I am running with 4 MB of RAM.  How large a swap file do I need?

Answer 16

Use a 2 MB permanent swap file for virtual memory and do not include a
MEMLIMIT setting in the CONFIG.FPW file.  Let FoxPro run with the
default setting.  In addition, do not use a RAM drive or an expanded
memory manager.  Expanded memory is not used by FoxPro for Windows. A
disk cache should be no larger than 256K.
------------------------------------------------------------------------
Question 17

If I am running with 5 MB or more of RAM, how large a swap file do I
need?

Answer 17

If you have 5 MB or more of RAM, do not use a swap file for virtual
memory.  Set your virtual memory to None and set MEMLIMIT to 90 in the
CONFIG.FPW file. Remember that devoting more memory to FoxPro means that
less memory is available for Windows and other applications that are
running.  FoxPro takes advantage of all the memory allocated for it.
Therefore, you must maintain the balance of memory allocated to FoxPro,
Windows and other applications that you intend to run. For more
information refer to the chapter on Optimizing your System in the
Installation and Configuration guide.
------------------------------------------------------------------------
Question 18

When using my Lantastic network card, why do I always get a memory
conflict when loading FoxPro for Windows?

Answer 18

Try putting EMMExclude=D800-DFFF in the SYSTEM.INI file in the Windows
directory.
------------------------------------------------------------------------
Question 19

When using a Paradise driver, why do I get a memory conflict when trying
to load FoxPro for Windows?

Answer 19

Try putting EMMExclude=C600-C800 in the SYSTEM.INI file in the Windows
directory.
------------------------------------------------------------------------
Question 20

When I use QEMM386 memory manager with FoxPro for Windows, why do I get
a memory conflict.

Answer 20

Try putting EMMExclude=C0FF-C7FF in the SYSTEM.INI file in the Windows
directory.
------------------------------------------------------------------------
Question 21

When I use the Mach32 video card with my Gateway 2000, why do I get a
General Protection Fault in module MACH32.DRV at 0003:0E22.

Answer 21

You are experiencing a problem with your video driver.  Contact your
video card vendor for the most recent version of the driver.  In the
meantime, you can use the VGA.DRV or the SUPERVGA.DRV drivers that come
with Windows.
------------------------------------------------------------------------
Question 22

I understand that a number of video drivers do not work properly with
FoxPro for Windows.  Why is this and what steps should I take to resolve
the situation?

Answer 22

FoxPro for Windows makes intensive use of screen I/O.  If you
are experiencing GPFs (General Protection Faults) or display problems
(borders, status bar, fonts, unusual alignment when previewing reports)
you may be experiencing a problem with your video driver. To test this
situation, load one of the standard Windows drivers and go through the
steps to reproduce the earlier problem.  If the problem no longer exists
when you are using a standard Windows driver, it is very likely that the
old driver was the cause of the problem.  Contact the vendor for an
updated version of the driver or download the Windows Driver Library
(WDL) on the Microsoft Download Service (MSDL). Complete instructions
for obtaining the Windows Driver Library is contained in the Product
Support section of this file.

We have identified problems with the following video cards:

   ATI Ultra Graphics Pro (local bus) -- caused GPF, fixed with update
   AST Power Premium 486 w/VGA on Motherboard -- fixed with update
   Genoa 7900 MM card
   Dell 486/20 with VGA on Motherboard
   Compaq QVision
   Speed Star 24x
   Trident 8900C
   TIGA 1024 x 768 x 256 small fonts
   NEC 2A
   MACH32

Contact your video card vendor for the most recent version of the driver
for your card.  In the meantime, you can use the VGA.DRV or the
SUPERVGA.DRV drivers that come with Windows.
------------------------------------------------------------------------
Question 23

I occasionally experience problems when trying to open more than 15
tables at one time.  What could be wrong?

Answer 23

Make certain you have the correct SHARE statement in your AUTOEXEC.BAT
file:

   SHARE /F:4096  /L:500
------------------------------------------------------------------------
Question 24

I'm running Windows for Workgroups.  Do I need to load SHARE?

Answer 24

No. Windows for Workgroups automatically loads VSHARE, which takes the
place of SHARE.
------------------------------------------------------------------------
Question 25

Where does FoxPro create its temporary files?

Answer 25

FoxPro creates its temporary files in the same directory where Windows
stores its temporary files, unless you specifically designate an
alternate location by including one or more of the EDITWORK, SORTWORK,
PROGWORK and/or TMPFILES statements in the CONFIG.FPW file.  The
location of Windows .TMP files is specified with the MS-DOS set variable
TEMP.  In most cases, you should let FoxPro write .TMP files to the same
location.  However, if this location is a RAM drive, make sure that
enough space is available for both FoxPro and Windows .TMP files.
------------------------------------------------------------------------
Question 26

I frequently use the RUN command to change drives and directories within
an application.  Why isn't this working in FoxPro for Windows?

Answer 26

Each time you issue the RUN command to change drives and directories,
Windows opens a new "session" of MS-DOS, otherwise known as a "virtual
machine", and executes the command within the newly created "session."
When you exit from this session or "shut down" the virtual machine,
you are right back where you started without having changed drives.
Consequently, you will want to take advantage of some of FoxPro's own
drive and directory commands instead of using the RUN command.  For
example, using SET DEFAULT TO c:\newdir will actually issue the MS-DOS
command CHDIR.
------------------------------------------------------------------------
Question 27

Why isn't FoxPro registered in REG.DAT within Windows?

Answer 27

Only OLE servers are registered in REG.DAT.  FoxPro is not an OLE server.
------------------------------------------------------------------------
Question 28

Why doesn't the value returned by SYS(2010) match the number of FILES
specified in the CONFIG.SYS file?

Answer 28

Windows interacts with the MS-DOS open file tables in such a way that
the value reported in the MS-DOS box and in Windows may be different.
------------------------------------------------------------------------
Question 29

What memory allocation options are available with the PIF settings?

Answer 29

In the PIF Editor "memory requirements" section the "KB Required" and
"KB Desired" may both be set to "-1".  This will tell Windows to give
all the available memory it can to a MS-DOS application.  This does not
mean that the MS-DOS application will have more than 600K, but it will get
about as much conventional memory as you had available before starting
Windows (minus some conventional memory that Windows itself occupies).

Changing the "EMS Memory" and "XMS Memory" sections will tell Windows to
provide or not provide the MS-DOS application and EMS (Expanded Memory
Services) or XMS (Extended Memory Services).  This will not, however,
allow an application that does not support accessing EMS or XMS to do
so. Only applications that have the capability will be able to access
the additional memory provided.  It is important to note that once you
tell Windows to create EMS or XMS for an application, it does so
whether the application can use it or not.

In the "Execution" section, if Exclusive is selected, no other
application, be it Windows or MS-DOS, will run while the application with
Exclusive is the current application.

In the "Advanced Options" there is a "Multitasking Options" section.
This section is very important when you are trying to get a MS-DOS
application to run in the background.  If the MS-DOS application is very
I/O intensive (reads and writes to disk, asynchronous communication,
etc.) it will be necessary to increase the "Background Priority".
Unfortunately there is no "rule of thumb" when it comes to the exact
number that should be used.  It is important to note that the larger the
number for "Background Priority" the slower other applications will run
while the MS-DOS application with the high priority is running in the
background.
