+# How to: Convert between various string types
 
-This topic demonstrates how to convert various Visual C++ string types into other strings. The strings types that are covered include `char *`, `wchar_t*`, [_bstr_t](../cpp/bstr-t-class.md), [CComBSTR](../atl/reference/ccombstr-class.md), [CString](../atl-mfc-shared/using-cstring.md), [basic_string](../standard-library/basic-string-class.md), and <xref:System.String?displayProperty=fullName>. In all cases, a copy of the string is made when converted to the new type. Any changes made to the new string will not affect the original string, and vice versa.

+## Example: Convert from `char *`
 
 ### Description
 
-This example demonstrates how to convert from a `char *` to the other string types listed above. A `char *` string (also known as a C style string) uses a null character to indicate the end of the string. C style strings usually require one byte per character, but can also use two bytes. In the examples below, `char *` strings are sometimes referred to as multibyte character strings because of the string data that results from converting from Unicode strings. Single byte and multibyte character (`MBCS`) functions can operate on `char *` strings.

+## Converting between narrow and wide strings
+
+Legacy C and Windows apps use code pages rather than Unicode encodings when handling narrow strings and wide strings.
+
+.NET strings are UTF-16, but ATL's `CStringA` is a narrow string, and the conversion from wide to narrow is performed by the [`WideCharToMultiByte`](/windows/win32/api/stringapiset/nf-stringapiset-widechartomultibyte) Win32 function. When converting a C-style `CHAR*` (a C-style `CHAR*` is a .NET `byte*`) to a string, the opposite Win32 function, [`MultiByteToWideChar`](/windows/win32/api/stringapiset/nf-stringapiset-multibytetowidechar) is called.
+
+Both functions rely on the Windows concept of a code page; not the .NET concept of a culture. To change the system code page, use the region setting using **Control Panel** > enter `Region` into the search box > **Region (change date, time, or number formats)** > **Administrative** > **Change system locale**.
+
+On an `en-US` language version of Windows, the code page defaults to 1033. If you install a different language of Windows, it will have a different code page. You can change it using the control panel.
+
+There's a mismatch in the way that `CStringA` performs a wide to narrow conversion and the way that `gcnew string(CHAR*)` performs a narrow to wide conversion. `CStringA` passes `CP_THREAD_ACP`, which means to use the current *thread* code page, to the narrowing conversion method. But `string.ctor(sbyte*)` passes `CP_ACP`, which means to use the current *system* code page, to the widening conversion method. If the system and thread code pages don't match, it can cause round-trip data corruption.
+
+To reconcile this difference, use the constant `_CONVERSION_DONT_USE_THREAD_LOCALE`) to get the conversion to use `CP_ACP` (like .NET) instead of `CP_THREAD_ACP`. For more information, see [_CONVERSION_DONT_USE_THREAD_LOCALE](https://social.msdn.microsoft.com/Forums/vstudio/en-US/f3820781-c418-40bf-8c4f-7250001e5b68/visual-studio-2015-update-1-implicit-string-narrow-wide-conversion-and).
+
+Another approach is to use [`pinvoke`](/dotnet/standard/native-interop/pinvoke) to call [`GetThreadLocale`](/windows/win32/api/winnls/nf-winnls-getthreadlocale). Use the returned `LCID` to create a [`CultureInfo`](/dotnet/api/system.globalization.cultureinfo). Then use `CultureInfo.TextInfo` to get the code page to use in the conversion.
