Java 1.1 introduced the java.awt.datatransfer package and its associated classes, which provide the foundation for capabilities such as cut-and-paste. On the surface, the API may appear complex, but this simple
The long long type denotes an integral data type that is at least as large as a long int. On 32-bit architectures and 64-bit architectures, long long occupies 64 bits
The order of evaluation of function arguments is unspecified. This means that for a function that takes the arguments (a, b, c), any permutation of this set is a valid
The ANSI/ISO C++ Standard is now available for downloading from the NCITS (National Committee for Information Technology Standards) Web site at http://www.cssinfo.com/ncitsgate.html. The downloadable PDF format costs $18. Note that
When working on developing or debugging an app created by automation (for example, by ActiveX DLL), if you normally invoke that app from a calling program (EXE), leave the calling
Have you ever wondered why your ActiveX DLL with a form doesn’t show up in the taskbar? Because you’re showing the form modally (.Show vbModal). VB4 only allows DLLs with

It is sometimes useful to be able to obtain a complete list of the components in a container hierarchy. A getComponents() method is provided in the java.awt.Container class, but it
Pausing SQL Server prevents new users from logging in and gives you time to send a message to current users asking them to complete their work and log out before
Pointer-based operations are less frequently needed than they might seem. For instance, examine this class declaration: class PointerMisuse{private: CDC * m_pDeviceContext;public: PointerMisuse(); ~PointerMisuse();};PointerMisuse::PointerMisuse(){ m_pDeviceContext = new CDC;}PointerMisuse::~PointerMisuse(){ delete m_pDeviceContext;} Even
When concatenating a SQL statement such as INSERT, you may have trouble if your field value contains an apostrophe (‘) such as in “Commedia Dell’Arte.” SQL thinks the apostrophe is
