Q:  I'm thinking about buying Delphi.  Where can I find more 
    information?

A:  Download the files TI2767.ZIP and TI2768.ZIP from Library 2 
    of this forum.


Q:  When I click on the 'Database Desktop' or the 'Database 
    Engine Configuration' icons, I get the error message 
    "multiple net files found".  How do I resolve this?

A:  Search your system for *.lck files and delete them.


Q:  How do I enable the Version Control capabilities of Delphi?

A:  Click on Help | Topic Search, enter in 'Version control'
    and follow the instructions.  This feature is only 
    available with the Client/Server edition.


Q:  I'm getting the error message "Out of Memory" or "Out of
    System Resources", but I have plenty of memory available!  
    What's going on?

A:  Try changing video driver to the Windows standard (vanilla-
    flavored) VGA driver.  To change your video driver, click 
    on the Windows Setup icon, then choose Options | Change
    System Settings.  If the error message doesn't appear any 
    more, then the video driver you were using isn't behaving 
    properly.  Contact the manufacturer of your video driver
    to get the latest version.  The reason for this strange behavior
    is that The exception is raised when a call to Create a Window 
    returns an error code rather than a window handle.


Q:  I already have Paradox for Windows and/or dBase for 
    Windows.  Will Delphi's version of the Borland Database 
    Engine coexist with these products?

A:  Yes, Delphi's newer version of the Borland Database Engine 
    (aka IDAPI) has been certified with Paradox for Windows and 
    dBase for Windows.

    Always install Delphi's IDAPI and SQL Links over any 
    earlier versions on your system.


Q:  I think I've found a bug in the product, how do I report 
    it?

A:  Download TI1171.ZIP and follow the instructions.


Q:  Where is the Language Reference Guide for Delphi?

A:  The Language Reference Guide is available separately.  
    Call the Order Desk at 800-331-0877 for pricing 
    information.


Q:  I'm running under Warp and I'm having problems getting
    Acrobat to work.  Any ideas?

A:  Go to the Acrobat Win-OS/2 session settings and set the 
    Win ATM selection to 'ON'.  You might also want to do the 
    same in the Win-OS/2 setup (in the system setup folder).


Q:  I'm trying to start Delphi and I get the error message 
    "can't open c:\delphi\bin\complib.dcl".  How do I fix this?

A:  This error message can occur for many reasons:  share or 
    vshare not loaded, using the wrong parameters for share 
    (should be F:4096 L:40).  The IDAPI section of the WIN.INI
    file is bad or missing.  It should read something like:
    
    [IDAPI]
    CONFIGFIL01=C:\IDAPI\IDAPI.CFG
    DLLPATH=C:\IDAPI

    COMPLIB.DCL could be corrupted.  Get a new copy from the CD
    ..\RUNIMAGE\DELPHI\BIN\COMPLIB.DCL

    Assumiming all of the above is as it should be, compare these files
    with the ones on the runimage:

    C:\WINDOWS\SYSTEM\COMPOBJ.DLL   108,544
    C:\WINDOWS\SYSTEM\OLE2.DLL      302,592
    C:\WINDOWS\SYSTEM\STORAGE.DLL   157,696
    C:\DELPHI\BIN\COMPLIB.DCL       1,058,784

    If any of these are the wrong size, back them up, and copy over new ones
    from the CD.

    If all the above fails, it is possibe that the Windows install
    is bad.  Some possible things to check:

    VER.DLL     9,008
    USER.EXE    264,016
    KRNL386.EXE 76,400


Q:  Adobe Acrobat gives the message "Could not find Adobe Type 
    Manager" when I try to access the Delphi on-line manuals.  
    I am running under Win NT.  How can I fix this problem?

A:  Download version 2.1 of the Acrobat Reader.  This new version
    works under NT, and supports a wider range of printers as well.
    You can find it in the Adobe Applications forum on Compuserve
    (GO ADOBEAPP).

    A current workaround to the problem is to add the line:
   
    ATMOption=1

    to the [Abode Viewer] section of ACROREAD.INI. Then 
    copy it to ACROEXCH.INI (both files should be in your 
    \winnt35 directory). If you do not have ACROEXCH.INI, then 
    copy acroread.ini and name it acroexch.ini. Fonts may still 
    show up incorrectly or poorly, but you will still be able to 
    run Acrobat. 

Q:  I'm writing an MDI application using Delphi.  When I
    minimize an MDI child, I get a GPF.  Is this a known 
    problem?

A:  Yes, this is a known problem which the patch fixed. 
    Download the patch (delpatch.zip), apply it, and then 
    rebuild the Library.


Q.  Why do I get the message "To run the interactive tutors, you must
    change the Delphi configuration slightly..." when I start the
    interactive tutors?

A.  This happens because you are not running with the default
    settings of Delphi.  Backup your current DELPHI.INI file in
    the Windows directory and then copy DELPHI.CBT file to 
    DELPHI.INI.  The tutors will now work correctly.  When
    finished with the tutors the old DELPHI.INI will need to be 
    restored.


Q.  The interactive tutors don't appear to be working correctly.
    How do I get them to work?

A.  See previous answer.


Q:  When I try to run the interactive tutors I get the message "Error
    creating Process: Insufficient memory to run the interactive tutors."
    How can I fix this?

A:  The interactive tutors have a larger memory requirement than Delphi,
    on the order of twice the amount.  Check to make sure you have enough
    memory to run the tutors.  You can still run the tutorials without
    12 or 16 megs, but make sure that you are running Windows in 386
    Enhanced mode, and that you have a large enough swap file set.  If
    you think you have enough RAM, but are getting the error message, try
    increasing your swap file anyway in the Virtual Memory option of the
    386 Enhanced control panel.  Windows may be trying to swap out things
    to disk to accomodate the Delphi tutorial, and if the swap file is too
    small, it may have trouble doing this.  Finally, clean boot your
    machine's Dos and Windows configuration, to make certain nothing
    you have loaded in memory besides the bare minimum is hogging or
    corrupting vital memory space necessary to run the tutors.  Download
    TI 1561 and TI 1283 from either Compuserve (TI1561.ZIP, TI1283.ZIP) or
    TechFax (1-800-822-4269) for detailed instructions on how to "clean
    boot" your machine.


Q.   I managed to delete the Delphi group and icons, or I did a manual install.
     How can I recreate it?

A.   There is a program for creating the Delphi program group and associated icons.
     The name of the file is  DLPGRP.ZIP.  It can be found in the "From Borland" 
     section of the "Borland Delphi" forum.


Q.   What is W8LOSS.EXE used for?

A.   W8LOSS.EXE is a command line tool that optimizes your exectuable for size
     and load time. It is equivalent to choosing OPTIONS|PROJECT|LINKER and
     turning on for 'optimize for size and load time.'  Use this tool if
     you are experiencing difficulty from using the option from within the
     IDE.


Q.   I did a manual install, what do I have to add to my WIN.INI and path
     for Delphi to function correctly? (Assuming Installed to C:)

A.   Add "C:\iblocal\bin;c:\delphi\bin" to the path in your autoexec.bat   
     Add the following lines to your WIN.INI   
	
	[IDAPI]
	DLLPATH=C:\IDAPI
	CONFIGFILE01=C:\IDAPI\IDAPI.CFG

	[Borland Language Drivers]
	LDPath=C:\IDAPI\LANGDRV

	[BWCC]
	BitmapLibrary=BWCC.DLL

	[Interbase]
	RootDirectory=C:\IBLOCAL

	[Paradox Engine]
	UserName=PxEngine
	NetNamePath=C:\
	MaxTables=64
	RecBufs=64
	MaxLocks=64
	MaxFiles=64
	SwapSize=64

	[DDE Servers]
	DBD=C:\DBD\DBD

	[DBD]
	WORKDIR=C:\DBD
	PRIVDIR=C:\DBD\DBDPRIV


Q:   I am running OS/2 Warp (no fixpak) and cannot run the default form 
     in Delphi without total system hangup.  The mouse doesn't respond, 
     all escapes to OS/2 unavailable, ctrl-alt-delete ignored. 

A:   Try turning off your ROM-Shadowing in your computers BIOS.



Q:      I get an error while trying to launch the Database Desktop, or
	while trying to access a table.  It says, "Could not initialize
	IDAPI" followed by a particular IDAPI error message, and then
	forces me to click "Ok", and quits.  How can I fix this?

A:      There are number of things you can check for that may be causing
	this error:

	First, make sure that the IDAPI paths in the [IDAPI] section
	of your WIN.INI are set correctly.  Go to your Windows directory
	and look at your WIN.INI file.  In particular, check that
	the following two lines:
		DLLPATH=C:\IDAPI
		CONFIGFILE01=C:\IDAPI\IDAPI.CFG
	are set to the correct paths.  Often,  if IDAPI was moved from
	a network or to another drive, these paths were not updated to
	reflect the change.  Also, check the private directory setting
	by double-clicking on  the Database Desktop Local Configuration
	icon.  Sometimes the path accidentally gets set to a shared
	directory or a network drive during the installation.  The private
	directory should be pointing to a non-shared directory on your local
	drive (e.g.:  C:\DBD\DBDPRIV).  Also, check the other paths settings
	within the Database Desktop Local Configuration to verify the paths
	are correct.  

	If this still doesn't resolve the problem, check your Net Control
	File Directory (NETDIR) setting for the Paradox driver by opening
	the BDE Configuration Utility, and, if you are not attempting to 
	open a table on the network, try setting it to a place on your local
	drive (e.g.: C:\).  If it is pointing to a drive on the network, 
	or you wish to open a table out on the network, make sure that  
	the directory exists, and that you have read/write access to it.
	In addition, everyone who has IDAPI installed on their machine and
	has their NETDIR setting pointing to a directory on the network MUST
	all have this NETDIR set to the SAME directory.  Until you can 
	determine this, scan the entire network for *.net and *.lck files,
	and delete them all.  A pdoxusrs.net file will be recreated in the
	directory you have the NETDIR set to.  Then make sure everyone points
	to this directory to prevent multiple net control files from being
	created. 

	Lastly, you can backup the idapi.cfg file from your IDAPI directory,
	and copy a fresh one over from the runimage off the CD rom.  If you
	had created aliases before backing up the idapi.cfg file, they will
	need to be re-created if you copy over a new idapi.cfg.  This can be
	done easily using the merge function within the Alias section of the
	BDE Configuration Utility.  Refer to the Database Engine
	Configuration Help for more information regarding merging.

	In addition to the above, you should already have share loaded with 
	the correct parameters.  Make sure you have the line:
		C:\DOS\SHARE.EXE /F:4096 /L:40
	somewhere in your autoexec.bat file.

	Should you be running Delphi on a Novel Lantastic 6.0 network, there
	is a known problem with the latest version of IDAPI that will not
	allow you to use Paradox tables on the network (possibly giving you
	this error).  Borland is aware of this, and is currently working on
	a fix for it.  Meanwhile, as a possible temporary workaround, you
	can try to switch your network driver down to an earlier version of
	Lantastic, such as Lantastic 5.0.  This has been known to work for
	most users as a temporary solution until a fix is available.
