The Essence of Object Oriented Programming with Java and UML

You have got written a few strains of Java code and created a couple of items, but that this does not represent real object-oriented programming. As a Java programmer, you must get extra from your efforts. This advent to the fundamentals of object-oriented programming and the Unified Modeling Language (UML) provide you with an organization starting place on which to construct top quality software program platforms that attain the complete good thing about an object-oriented technique.

Concepts in programming languages

Thoughts in Programming Languages elucidates the principal recommendations utilized in smooth programming languages, comparable to features, forms, reminiscence administration, and keep an eye on. The e-book is exclusive in its complete presentation and comparability of significant object-oriented programming languages. Separate chapters learn the heritage of gadgets, Simula and Smalltalk, and the well-known languages C++ and Java.

Computing patterns in strings

The computation of styles in strings is a basic requirement in lots of parts of technological know-how and data processing. The operation of a textual content editor, the lexical research of a working laptop or computer software, the functioning of a finite automaton, the retrieval of knowledge from a database - those are all actions that may require that styles be situated and computed.

Building Web Applications with ADO.NET and XML Web Services

How to construct a data-intensive net software with XML internet companies and ADO. internet! Richard Hundhausen, Steven Borg, Cole Francis, and Kenneth Wilcox have mixed their years of craftsmanship during this important source to coach you ways a regular stressed enterprise can leverage net prone in B2B trade.

Sample text

But once you switch to a component implemented in a different programming language or exercise the interface across processes, all hell breaks loose. The COM+ binary compatibility standard is language independent, but only some execution environments detect certain problems. Another thing to watch out for is the fact that NULL is always a valid BSTR empty string. In fact, attempting to distinguish between OLESTR("") and NULL in C++ is not recommended because higher-level development environments might not support such a distinction.

With it, you ought to be able to take advantage of the #import directive's programming model simplifications even in projects that use versions of the interfaces generated by the MIDL compiler. If you have many functions like Bar or functions that take multiple parameters to which these considerations apply, you might want to cast these parameters instead in terms of a class that can translate between the interface types. Such a solution might take the following shape. The sample shows a Bar function, which needs one interface MyProject::IFoo by reference and a reference to an interface pointer MyProject::IFoo.

34 String Conversion Macros Regardless of the string handling strategy and project settings you adopt in your COM+ project, you will very likely need to convert a string from one character encoding representation to another from time to time. The Win32 API provides functions MultiByteToWideChar and WideCharToMultiByte, which convert Unicode to ANSI/DBCS and vice versa, respectively. These functions provide a variety of options and let you explicitly control which code page ought to be used for the translation.
