You can take the addresses of a class’s static and non-static member functions. However, the class’s constructor(s) and destructor are an exception to the rule. You cannot take their addresses

You can optimize data access to remote servers by adjusting the size of the network packet. Configuring the packet size provides a choice between responsiveness and overall throughput. Larger packets

You can enable the “Boost SQL Server Priority” option, to allow SQL Server threads to run in the real time priority class. When running at this priority level, SQL Server

You can set SQL Server to display information regarding the amount of disk activity generated by T-SQL statements. This option displays the number of scans, the number of logical reads

You can create an aggregate column in a SQL 7.0 table by specifying it during creating the table itself. This is useful if you want that aggregate column to be

This T-SQL command can be used to display the number of milliseconds required to parse, compile, and execute each statement. When SET STATISTICS TIME is ON, the time statistics for

In DAO recordset, there is no separate refresh command to refresh the current recordset. However, you can call Move member function to position the recordset lRows records from the current

In standard C++, declaring arrays with zero elements is illegal: int n[0]; //illegal However, certain compilers do support arrays of zero size as non-standard extension. In contrast, dynamic allocation of

While the overhead of returning an ordinary object by value may be acceptable in most cases, returning a container by value is much more expensive in terms of performance. For

The time functions of standard C/C++ are limited to the resolution of a second. In general, you can access smaller time units

The representation of floating point numbers is just an approximation. Truncation and rounding occur frequently because the hardware cannot offer infinite precision when using a fixed number of bits. For

MS Visual C++, as well as several other compilers, now offer non-standard keywords that control the inline expansion of a function, in addition to the standard inline keyword. What are

Although the default arguments of a function must appear in its declaration, they are not considered part of its type. Thus, you cannot overload a function by using different default

Default arguments shall be specified only in the parameter-declaration-clause of a function declaration or in a template-parameter. This means that default arguments cannot appear in declarations of pointers to functions,

You can declare a reference to a function, just like you can declare a pointer to a function. For example: void f(int n){ ++n;}int main(){ void (&rf) (int) = f;

The order of evaluation of function arguments is unspecified. Consequently, parameters of a function may not be used in default argument expressions. For example, the following declaration is illegal: int

It is guaranteed that sizeof(char), sizeof(signed char) and sizeof(unsigned char) all equal 1. Applying sizeof to any other fundamental type returns an implementation-defined value. In particular, sizeof(bool) and sizeof(wchar_t) need

If your application uses exception handling, it is recommended that you always add a catch(…) statement after all the existing catch statements. Remember that even if your code contains the

Question: Is there a way to host an MDI form from an ActiveX DLL in a Main application’s MDI Parent Form? Answer: Although I’ve never tried it, I don’t think

Table type recordsets are probably the best of all performance boosters. DAO provides three recordset types: dynaset, snapshot, and table. Of these three types, the table recordset type is the

STL includes the random_shuffle() algorithm. As the name suggests, this algorithm randomly shuffles the elements of a sequence. It takes two arguments, the first of which is an iterator that

Question: I am building a Web site that is hosted on Microsoft’s Personal Web Server. I have an Active Server Page (ASP) with some graphics on it. Everything works fine

Java Server Pages (JSP) are a complementary Java API to Java Servlets. They let you publish dynamic Web content. A JSP can contain HTML tags, scripts written in Java code,

JDK 1.1.x’s java.io.File class has a lastModified():long method. You can use the value returned by lastModified method to create an instance of java.util.Date class and, thus, get a hold of
