Decompilers can recreate DataFlex source code from a
compiled .FLX file in case the original source code
is ever lost. Over the past twenty years, DataFlex Decompilers
have helped thousands of developers worldwide to recover
lost source code. DataFlex programs can be decompiled
using our service. The Database Managers is able to
decompile DataFlex programs that were compiled on either
a Motorola or Intel style processor.
decompiles DataFlex FLEX.CFL files into FMAC files.
All of the original DataFlex macros are restored, along
with all of the custom macros dfpacked in the FLEX.CFL.
Database Managers also offers full-service DataFlex
programming services for DataFlex users. For existing
applications, our decompiler technologies allow us to
verify that the source code you're providing us is the
same source code that was used to compile your existing
programs. This means no surprises when the DataFlex
code is changed and installed into your live application.

Interview Questions and Answers:
Unless you're a hobbyist, at some point in your career
you will be interviewed for a software development position.
In addition to knowing the company, knowing their industry,
knowing their products and practicing standard interviewing
questions ("So why do you want to work for us?"), software
engineers are expected to be able to communicate their
knowledge of their art and demonstrate their skills
on demand. Prepare for your next C++ job interview by
reviewing the questions on these pages. Use the questions
that have been grouped into 13 categories to test your
ability to handle typical C++ programming questions
and to handle the extraordinary and unusual programming
3.4 C++ Open Source Library Review:
This is an update to the first article that appeared
in the Not Invented Here
Open Source Reviews web pages. STLplus
version 3.4 is an update to the originally reviewed
STLplus 2.5. STLplus is a collection of STL C++ components.
The areas covered in STLplus range from the mundane
(trimming strings) to advanced (directed graphs, hash
tables and file management).
A Java-like C++ Open Source Library:
JavaLib is a small library of Java-like classes written
in C++. The size of the library promotes portability
and maintainability by end-users. For the right project,
JavaLib can be quite helpful in providing containers
that are much simpler to use than the STL but provide
all of the power of template programming.
3.19 Command Line Parser Open Source Library Review:
is a command line parsing library for C++ and C programs.
It provides an automatically generated user interface,
an automatically generated help screen and it can read
parameters from files and environment variables and
create files using the current set of parameters.
a Printer to a USB Port on Windows 2000:
Making a MS-Dos application print
to a USB port can be very tricky. This page gives
detailed instructions for allowing your old Dos programs
to print to your new USB-only printer. Instructions
are also provided for detecting
when the user is an administrator and for opening
a Dos Box.
a text file into a vector of strings:
This is an example program that reads
itself using the STL std::copy algorithm. The file
is read into a std::vector of char. This example uses
istream_iterator, back_inserter and the noskipws manipulator
to read the file.
an Exception using a Macro
Define a C++ exception using a macro. The
article includes exception examples for Microsoft
C++ compilers, for Borland C++ compilers and GNU compilers.
All Datafile Saves and Deletes:
DataFlex module helps a developer discover why records
are being mysteriously deleted or overwritten. It does
this by logging the key fields and other important information
when a specific datafile is saved or deleted. This solution
is suitable for character-mode DataFlex.
Windows API Lookup Tool:
A tool to make
it easier for VDF (Visual DataFlex) programmers to create
Windows API calls.
A DataFlex solution of the classic problem of finding
the monthly payment for a loan.
a file into a string vector:
This small program shows how to read
an entire file into a C++ STL vector.
