<br>内容：除了MessageBoxW等少数函数以外，一般W后缀的函数是不能在98以下的操作系统中用的。<BR><BR>Unicode Functions Supported by Windows 95<BR>The information in this article applies to:<BR>Microsoft Win32 Software Development Kit (SDK)<BR><BR>SUMMARY<BR>Unlike Windows NT, Windows 95 does not implement the Unicode (or wide character) version of most Win32 functions that take string parameters. With some exceptions, these functions are implemented as stubs that simply return success without modifying any arguments. <BR><BR>In general, Windows 95 implements the ANSI version of these functions. See the Win32 API documentation for information on particular functions and differences between the various Win32 platforms. <BR><BR>One major exception to this rule is OLE. All native 32-bit OLE APIs and interface methods use Unicode exclusively. For more information on this, please see the OLE documentation. <BR><BR>Excluding OLE, Windows 95 supports the wide character version of the following functions: <BR>EnumResourceLanguages <BR>EnumResourceNames <BR>EnumResourceTypes <BR>ExtTextOut <BR>FindResource <BR>FindResourceEx <BR>GetCharWidth <BR>GetCommandLine <BR>GetTextExtentExPoint <BR>GetTextExtentPoint32 <BR>GetTextExtentPoint <BR>lstrlen <BR>MessageBoxEx <BR>MessageBox <BR>TextOut <BR><BR>In addition, Windows 95 implements the following two functions for converting strings to or from Unicode: <BR>MultiByteToWideChar<BR>WideCharToMultiByte <BR>
