You can do this while testing a true/false condition that has a set third variable as shown in following loop: if ( x < y) z = true; else z
You can declare the counter of even the most deeply nested loop as a ‘register’ variable. For example: for (int i = 0; i < 100; ++i){ for (register int
If you are using MS Visual C++ to develop your application or DLL, then this may help. MS Visual C++ 6.0 introduces new linker optimization options: /OPT:WIN98, which is set
Global inline functions, consts and typedefs have internal linkage.That means that the declarations in these two files do not interfere with each other: //File1.c typedef int T; const int a
This tips explains how to list members in an initialization list in the order in which they are declared. Take a class Array: class Array {private: int *m_piData; // ptr

Universal Data link files are handy for select data sources but there isn’t a way to create/edit this files. This little class shows how to read/write a UDL file. ‘———————–‘
‘ve been listening with interest to the reactions that VB programmers have had to the new VB.NET environment and have been surprised to hear so many complain that VB.NET is
The Regular Expression Tester Add-in is a VB6 add-in that lets you test a VBScript regular expression without having to create a quick-and-dirty VB test program just for that. You
When parsing a text file that contains quoted strings – such as a VB source file – you might want to quickly locate and extract all the quoted strings. Thanks
Regular expressions offer an extremely powerful way to search and replace text inside a string using sophisticated search criteria, far behind the capabilities of VB’s InStr and Replace functions. For
A Visual Basic function that counts the number of words in a sentence or text file can become quickly very complex, and usually doesn’t execute fast enough for most purposes.
The following routine extracts all the words from a source string and returns a collection. Optionally, the result contains only unique words.This code is remarkably simpler than an equivalent “pure”
By changing the WS_CHILD style bit of a window, you can make it appear as if it is disabled, even if the form is fully active and functional. These are
Suppose you have an aggregate, i.e., a struct or a union that contain another struct as a member: struct A{ int x; int y;};union B{ A var1; float var2;}; Can
The std::auto_ptr class template handles only a pointer to a single object. This is because it uses scalar delete, never delete[], to destroy the owned object. Therefore, binding auto_ptr to
The Standard Library defines several template adaptors for function pointers. The std::pointer_to_unary_function class template encapsulates a pointer to a single argument function. std::pointer_to_unary_function overloads the () operators so that you
You can initialize static arrays member of a class. The initialization must appear at the place of definition, not inside the class body. For example: class A{private: static char vars[2];
The preprocessor ## operator concatenates macro arguments. For example: #define paste(x,y) x ## y The paste() macro takes two arguments and concatenates them into one. The whitespaces surrounding the ##
Memory is precious in Palm OS, since the total amount of memory available is very small. Dynamic memory allocation is often necessary while building applications in which memory at runtime
