Unicode in MFC

 

The latest version of this topic can be found at Unicode in MFC.

MFC supports the Unicode standard for encoding wide characters on Windows NT, Windows 2000, and Windows XP platforms. Unicode applications cannot run on Windows 98 platforms.

The Unicode versions of the MFC libraries are described below:

Release Debug Description
UAFXCW.lib, .pdb UAFXCWD.lib, .pdb Unicode MFC static link library
Release Debug Description
MFC100U.lib, .dbg, def, .dll, .map, .pdb, .prf MFC100UD.lib, .def, .dll, .map, .pdb Unicode MFC import library (see notes below for explanation of file extensions)
MFCS100U.lib, .pdb MFCS100UD.lib, .pdb Unicode MFC import library containing code that must be statically linked in an application or DLL

File Types

  • Import library files have the extension (.lib).

  • Dynamic-link library files have the extension (.dll).

  • Module definition (.def) files are text files that contain statements for defining an .exe or .dll.

  • Map (.map) files are text files that contain information that the linker uses when linking a program.

  • Library (.lib) files are used in conjunction with the DLL versions of MFC. These files contain code that must be statically linked in the application or DLL.

  • Program database (.pdb) files contain debugging and project state information.

  • Debug (.dbg) files contain information (COFF FPO, and CodeView) that the Visual C++ Debugger uses.
