NEW FEATURES
***************
TCW 4.5 includes the following new features:
OLE SUPPORT:
- A complete encapsulation of OLE2 via new ObjectWindows classes
and the ObjectComponents Framework, a new set of C++ classes. This
allows you to develop applications that support the following
16-bit OLE capabilities:
* Linking and embedding containers
* Linking and embedding servers
* Automation servers (automatable servers)
* Automation controllers
* OLE clipboard operations
* OLE drag and drop operations
* In-place editing
* OLE user interface, including menu merging, pop-up menu
for activated object, verbs on container's Edit menu
* Compound file storage
* Registration
* Localized strings for international support
* Type libraries
- New utilities to make OLE programming easier:
* WinRun allows you to launch Window application from the
MS-DOS prompt in Windows 3.1. (See UTILS.TXT for
more information.)
* AutoGen, MacroGen, GuidGen produce helpful class
declarations, macro,s and OLE identifiers automatically
* DllRun and Register simplify running and testing DLL
servers
- IDE enhancements to TargetExpert, AppExpert, and Clas****pert to
support the new OLE2 capabilities.
COMPILER FEATURES
- Support for ANSI C++ exception handling, structured exception handling
under C, and mixed C/C++ exception handling.
- Support for ANSI C++ operator new[] and operator delete[].
- Runtime Library support for the ANSI C++ string class.
- Support for ANSI C++ runtime type identification (RTTI).
- Support for ANSI C++ new style casts dynamic_cast, static_cast, const_cast,
and reinterpret_cast.
- Support for three character types as provided in ANSI C++.
LINKER FEATURES
- Linker debug capacity expanded.
IDE FEATURES
- Integrated GUI debugging for 16-bit Windows applications.
- A new project manager that supports multiple targets, drag-and-drop,

- Single source for Win 3.1, Win 32s, and NT
(building 32-bit applications requires Borland C++)
- Built in exception handling using standard C++ exceptions for robust error
handling
- Built-in type safety using standard C++ templates
- Toolbars, status lines, and print preview
- Flexible Document/View architecture
- Supports VBX 1.0 controls in a dialog or window
- Layout Windows
- Mix-in architecture

BLOCKS
CRIBBAGE

DOCUMENTATION FEATURES
- OpenHelp, a utility that enhances the functionality of Windows Help
by allowing you to quickly search for topics across Help files, as
well as the ability to add your own Help files (or remove them) from
the search.
- Documentation in the Acrobat 2.0 document viewing browser.
Acrobat lets you search through the entire documentation set to find
selected topics. You can view the contents page by page and
print sections of particular interest.
VBX SUPPORT
- Borland's visual tools, such as Resource Workshop, provide
support of VBX 1.0 controls via a DLL called BIVBX11.DLL. You can
freely distrubute this DLL with programs you create that use VBX
controls.
BIVBX11.DLL has been tested with a large number of VBX controls written to
the Microsoft Visual Basic 1.0 CDK specification. If you have a problem with
a specific control, make sure that it does not require VB 2.0 or VB 3.0 CDK
functionality. VBX 2.0 and 3.0 controls will usually display a message saying
that they require VB 2.0 or 3.0 support. In some cases, though, the control
may appear to work but exhibit instability. Please contact the control vendor
and explain the problem. They may have an updated control or may be able to
contact Borland to find a solution.
------------------
Acrobat Reader 2.0
------------------
The four books available online duplicate material
already in the online Help. We recommend using the Acrobat
Reader to read long sequences of material in order and
the online Help when searching for specific information by
keyword.
The Acrobat Reader is capable of high-quality printed
output. You might prefer to print sections of the manuals
that you use frequently.
--------------------------------------------
Importing Project Files from Borland C++ 4.x
--------------------------------------------
When TCW loads an .IDE file created with Borland C++, it
shows a dialog box warning that the project might contain
target types and option settings that TCW does not
support. If you click Yes to import a BC project, TCW
ignores any optimization settings the project might
contain. The TCW project manager displays DOS targets and
Win32 targets, but attempting to build them causes errors.
For more details about what project features might
cause problems for TCW, click the Help button in the
warning dialog box.
You can disable the dialog box, if you prefer, with the
following setting in your TCW.INI file.
[Project]
ImportBorlandIDEFile=1
With this setting, TCW automatically converts any .IDE
file without warning.
Borland C++ reads TCW .IDE files without difficulty.
TCW 4.5 does not support development of OWL 1 applications.
The differences between OWL 1 and the current OWL 2.5 are
large enough to render them incompatible. You will need to
convert your OWL 1 programs to use OWL 2.5 before you can
build them. For help converting, see Appendix A of the
ObjectWindows Programmer's Guide in the online
documentation.
--------------------
Quick Tour Help File
--------------------
To get you started quickly with using Turbo C++ for Windows, take
a look at the online Quick Tour. The Quick Tour provides an
overview of the product, with animated demonstrations of its many
features.
System Requirements
-------------------
Although you can view the Quick Tour at any screen resolution, a
resolution of at least 800 x 600 is recommended.
----------------------
C/C++ Language Changes
----------------------
Many changes were made to the compiler in compliance with the
latest changes proposed by the ANSI C++ committee. These include
three distinct char types, enhancements to templates, support for
virtual functions differing in return types, and other improvements
listed here. See the Library Reference and the Programmer's Guide
for complete details on these changes and how they affect your
code.
wchar_t is a fundamental data type in C++ programs. In C programs it
continues to be a typedef defined in stddef.h. See online Help.
Enum operator overloading is also supported.
The runtime library now supports the ANSI C++ string class. If you
already have a string class, it must be renamed for Turbo C++ 4.5.
In addition, operator new and operator new[] now throw an
exception (xalloc), as specified by the ANSI C++ committee.
To get the old behavior, you can issue set_new_handler(0).
(set_new_handler(0), however, does not work with ObjectWindows
or string classes.) See Chapter 3 of the Programmer's Guide.
Arrays are now being allocated through operator new[]() and deleted
by operator delete[](). An example is provided in Chapter 3 of the
Programmer's Guide.
Turbo C++ 4.5 implements ANSI C++ runtime type identification (RTTI).
See the Library Reference, "C++ runtime support", for a description
of class Type_info. RTTI and operator typeid() are fully described in
Chapter 3 of the Programmer's Guide.
Turbo C++ provides a full implementation of exception handling
under C++ and C. C exceptions can be handled in C or C++ code;
C++ exceptions can be handled only in C++ code. The C++ exceptions are
described in the Library Reference, "C++ run-time support." See Chapter 4
of the Programmer's Guide for a full description of how to use exception
handling.
Turbo C++ 4.5 also implements the accepted ANSI C++ new style casts.
See the Chapter 3 of the Programmer's Guide for information and
examples.
