MultiByteToWideChar() maps a character string to a wide-character string.
The declaration of this application programming interface (API) is as follows: int MultiByteToWideChar(uCodePage, dwFlags, lpMultiByteStr, cchMultiByte, lpWideCharStr, cchWideChar) UINT uCodePage; /* codepage */ DWORD dwFlags; /* character-type options */ LPCSTR lpMultiByteStr; /* address of string to map */ int cchMultiByte; /* number of characters in string */ LPWSTR lpWideCharStr; /* address of wide-character buffer */ int cchWideChar; /* size of wide-character buffer */ The first parameter, uCodePage, specifies the codepage to be used when performing the conversion.
This discussion applies to the first parameter of WideCharToMultiByte() as well. The codepage can be any valid codepage number. CP_ACP ANSI codepage CP_OEMCP OEM (original equipment manufacturer) codepage CP_ACP instructs the API to use the currently set default Windows ANSI codepage. Guide lines.

It allows an element to be visible only within the same namespace. It's a wonderful thing. Here's how it works in Java: package com.pc-doctor.mynamespace; package class Foo { ... } The class Foo is only visibile within mynamespace. Even though I'm not a Java programmer, this immediately strikes me as extremely useful. There are two reasons to want namespace visibility to be enforced by your compiler: If you can make those classes invisible outside the namespace, it will make life a lot easier for clients of that namespace. The Microsoft Way Microsoft expects you to make the classes internal. However, you have to make a separate assembly for each namespace that you want to do this with. Frankly, that's painful enough that few people do it. Comprehensive TOC. C++ FAQ LITE. Untitled.
Definition: Streams are a replacement for printf() and scanf().
Pros: With streams, you do not need to know the type of the object you are printing. You do not have problems with format strings not matching the argument list. (Though with gcc, you do not have that problem with printf either.) Streams have automatic constructors and destructors that open and close the relevant files. Cons: Streams make it difficult to do functionality like pread().
Decision: Do not use streams, except where required by a logging interface. There are various pros and cons to using streams, but in this case, as in many other cases, consistency trumps the debate. Extended Discussion There has been debate on this issue, so this explains the reasoning in greater depth. Proponents of streams have argued that streams are the obvious choice of the two, but the issue is not actually so clear.
