    TITLE  :  Understanding the Configuration and Project Files




  Upon entering Borland C++'s Integrated Development Environment
  (IDE), the compiler looks in the current directory for certain
  configuration files.  If these files are not found, Borland C++
  looks in the directory where BC.EXE is located.  (If you are
  running Borland C++ for Windows, then it looks where BCW.EXE is
  located).

  The files are as follows:

  (for DOS IDE)       - TCCONFIG.TC, TCDEF.DPR, TCDEF.DSK

  (for WINDOWS IDE)   - TCCONFIG.TC, TCDEFW.DPR, TCDEFW.DSK

  TCCONFIG.TC:  Contains global environmental information, and is
  automatically saved if Options|Environment|Preferences has Auto-
  Save for the Environment checked.

  TCDEF.DPR:
  Contains information needed to build a program, ie: compiler
  options, directory paths, memory model etc.  This information is
  saved in your own project file, (if defined; example->
  MYPROJ.PRJ), otherwise it is written to this file.

  TCDEF.DSK:
  Contains information for positioning and opening of windows,
  history lists, watch expressions and breakpoints.  If you have a
  project file open, this information is saved in MYPROJ.DSK,
  otherwise it is written to this file.  See
  Options|Environment|Preferences, Auto-Save for Desktop.


  Q:   Every time I enter the IDE, I get all my old settings, how
       do I get rid of these settings, to an original default IDE?

  A:   First look in your current directory you are executing
       BC.EXE from.  If have a *.PRJ file in this directory, it
       will read this file and load the settings specified in this
       file.  If you have more than one *.PRJ file in this
       directory, or do not have a *.PRJ file at all in your
       working directory, the compiler will default to your
       BORLANDC\BIN directory and load the TCDEF.PRJ and TCDEF.DSK
       files.  If the settings that are loaded are not what you
       desire, you can safely delete the TCDEF.DPR, TCDEF.DSK and

       TCCONFIG.TC files.  These files are automatically created
       again with default settings upon entering the IDE.

  Q:   When I enter the IDE, I get an exception error or I get just
       overall strange behavior when attempting to load a file,
       edit or merely Zoom a window.

  A:   The project, desktop and environment files can become
       corrupted.  This most often happens when you have your
       Options|Environment|Preferences set to AutoSave for these
       three files.  (The following scenario is an example of how
       this can happen):  Suppose you are compiling and running a
       file from within the IDE.  You experience a crash or hang
       within the execution of your program.  This typically
       happens because of corrupted memory or a stray pointer that
       is dereferencing unallocated memory.  At the same time, an
       Auto-Save was executed on the project/desktop and
       environment files, and during the save these files became
       corrupted.  We recommend that if you feel this has happened,
       to delete your project and desktop files (MYPROJ.PRJ and
       MYPROJ.DSK) and rebuild them.  In addition you may need to
       delete the environment file: TCCONFIG.TC that is located in
       the BORLANDC\BIN directory.  If you are not working with
       your own project, then you should proceed to delete the
       default files:  TCDEF.DPR and TCDEF.DSK in the BORLANDC\BIN
       directory.  Be assured that these files will be rebuilt
       again upon entering the IDE.

  Q:   I have a project file in my working directory, however, it
       is not automatically being read when I enter the IDE.  Why?

  A:   If you have multiple .PRJ files in your working directory,
       the IDE does not know which .PRJ file to read, and therefore
       defaults to the default project and desktop files located in
       the BORLANDC\BIN directory to read instead.  If you require
       different settings for multiple projects that you are
       working with, we suggest that you create separate
       directories for each project.  That way you will only have
       one .PRJ file in the subdirectory when you execute bc.exe
       that will be read and automatically load your desired
       settings for that project.

  Q:   How can I reduce this corruption of project and desktop
       files?

  A:   We suggest that you turn off Auto Save for the Project,
       Desktop and Environment under
       Options|Environment|Preferences.  Then manually do an
       Option|Save when you make changes to your environment,
       desktop, or project compiler settings, when your system is
       stable.
