.NET 2.0 Interoperability Recipes: A Problem-Solution Approach

. internet represents a brand new and more desirable method of constructing software program for the home windows platform. Given the opportunity, youТd most likely rewrite all your current code within the more moderen controlled code atmosphere that . internet presents. however it is tough or very unlikely to throw out all present legacy code and begin over whilst a brand new know-how arrives.

Microsoft.NET Compact Framework Kick Start

Microsoft . web Compact Framework Kick begin is the quickest route to getting to know the Microsoft . internet Compact Framework - Microsoft's subsequent iteration improvement framework for growing complicated functions for the Pocket laptop and home windows CE structures. utilizing it, you could leverage your wisdom of C# or visible simple programming through the use of a similar languages on units.

Pro Asp.net Extensibility

New dynamic languages like IronPython have gotten more and more well known as builders circulation clear of statically-compiled functions. ASP. internet, Microsoft’s well known net platform, can now help builders shedding in those dynamic runtimes, commencing up the platform to a large choice of builders and programmers who haven’t up beforehand been capable of use Microsoft applied sciences.

The draft Standard C++ library

This paintings offers the library component to the draft ANSI/ISO normal for the programming language C++, and exhibits the best way to use all library sessions and capabilities mandated by way of that draft regular. An introductory bankruptcy discusses how the normal C library adjustments to satisfy the desires of C++. all the 38 headers is then coated utilizing a similar layout: a dialogue of ways the explicit component to the library is in general used, excerpts from suitable parts of the draft, the code had to enforce the actual component and to check the implementation, and routines and references

Sample text

At the end of the year, Haavard suggested that they go into business together to build "the world's best C++ GUI framework". The year 1994 began inauspiciously with the two young programmers wanting to enter a well-established market, with no customers, an unfinished product, and no money. Fortunately, their wives were employed and therefore able to support their husbands for the two years Eirik and Haavard expected to need to develop the product and start earning an income. The letter 'Q' was chosen as the class prefix because the letter looked beautiful in Haavard's Emacs font.

The code generated by moc includes this header file and adds some C++ boilerplate code of its own. Classes that use the Q_OBJECT macro must have moc run on them. This isn't a problem because qmake automatically adds the necessary rules to the makefile. But if you forget to regenerate your makefile using qmake and moc isn't run, the linker will complain that some functions are declared but not implemented. The messages can be fairly obscure. obj : error LNK2001: unresolved external symbol "public:~virtual int __thiscall MyClass::qt_metacall(enum QMetaObject ::Call,int,void * *)" If this ever happens to you, run qmake again to update the makefile, then rebuild the application.

For moc to work correctly, we must put the class definition in a header file, separate from the implementation file. The code generated by moc includes this header file and adds some C++ boilerplate code of its own. Classes that use the Q_OBJECT macro must have moc run on them. This isn't a problem because qmake automatically adds the necessary rules to the makefile. But if you forget to regenerate your makefile using qmake and moc isn't run, the linker will complain that some functions are declared but not implemented.
