MFC 多语言系统的制作
对于软件系统，我们可以常看到其支持做种语言系统，比如中文、英文等等。那么在MFC中如何实现呢？其实很简单。制作流程如下。一下以最简单的对话框为列做个示范，大系统同样是该流程。(这里IDE使用 VC6.0 )
1、创建简单的对话框应用程序Dlg，同时添加Static文本控件。
2、创建动态库项目S_Chinese(空项目则可)，然后把步骤一中所说的项目下的res文件夹、.rc文件、.resource.h、stdafx.h、stdafx.cpp文件拷贝到创建的动态库项目中，同时添加进工程，如下图所示
并将要修改的资源在此处进行修改。
3、S_Chinese.h 和S_Chinese.cpp文件可以直接从上面对话框项目的Dlg.h Dlg.cpp 并做一下修改便可。
Dlg.h
// Dlg.h : main header file for the DLG application
//
#if !defined(AFX_DLG_H__D1CC9B6F_8745_458B_9432_BB3DD26912FF__INCLUDED_)
#define AFX_DLG_H__D1CC9B6F_8745_458B_9432_BB3DD26912FF__INCLUDED_
#if _MSC_VER > 1000
#pragma once
#endif // _MSC_VER > 1000
#ifndef __AFXWIN_H__
#error include 'stdafx.h' before including this file for PCH
#endif
#include "resource.h" // main symbols

ON_COMMAND(ID_HELP, CWinApp::OnHelp)
END_MESSAGE_MAP()
/////////////////////////////////////////////////////////////////////////////

// CDlgApp initialization

{
AfxEnableControlContainer();
// Standard initialization
// If you are not using these features and wish to reduce the size
// of your final executable, you should remove from the following
// the specific initialization routines you do not need.
#ifdef _AFXDLL
Enable3dControls(); // Call this when using MFC in a shared DLL
#else
Enable3dControlsStatic(); // Call this when linking to MFC statically
#endif
HINSTANCE hInst;
hInst=LoadLibrary("S_Chinese.dll");
if(hInst!=NULL)
AfxSetResourceHandle(hInst);
CDlgDlg dlg;
m_pMainWnd = &dlg;
int nResponse = dlg.DoModal();
if (nResponse == IDOK)
{
// TODO: Place code here to handle when the dialog is
// dismissed with OK
}
else if (nResponse == IDCANCEL)
{
// TODO: Place code here to handle when the dialog is
// dismissed with Cancel
}
// Since the dialog has been closed, return FALSE so that we exit the
// application, rather than start the application's message pump.
return FALSE;
}
修改如下：
S_Chinese.h
// S_Chinese.h : main header file for the S_Chinese DLL
//
#if !defined(AFX_S_Chinese_H__434B3D70_1ED9_44C1_B0B4_E51CB2EF620C__INCLUDED_)
#define AFX_S_Chinese_H__434B3D70_1ED9_44C1_B0B4_E51CB2EF620C__INCLUDED_

#pragma once
#endif // _MSC_VER > 1000

#endif
#include "resource.h" // main symbols

};
/////////////////////////////////////////////////////////////////////////////
//{{AFX_INSERT_LOCATION}}
// Microsoft Visual C++ will insert additional declarations immediately before the previous line.
#endif // !defined(AFX_S_Chinese_H__434B3D70_1ED9_44C1_B0B4_E51CB2EF620C__INCLUDED_)
S_Chinese.cpp
// S_Chinese.cpp : Defines the initialization routines for the DLL.
//
#include "stdafx.h"
#include "S_Chinese.h"
#ifdef _DEBUG
#define new DEBUG_NEW
#undef THIS_FILE
static char THIS_FILE[] = __FILE__;
#endif
//
// Note!
//
// If this DLL is dynamically linked against the MFC
// DLLs, any functions exported from this DLL which
// call into MFC must have the AFX_MANAGE_STATE macro
// added at the very beginning of the function.
//
// For example:
//
// extern "C" BOOL PASCAL EXPORT ExportedFunction()
// {
// AFX_MANAGE_STATE(AfxGetStaticModuleState());
// // normal function body here
// }
//
// It is very important that this macro appear in each
// function, prior to any calls into MFC. This means that
// it must appear as the first statement within the
// function, even before any object variable declarations
// as their constructors may generate calls into the MFC
// DLL.
//
// Please see MFC Technical Notes 33 and 58 for additional
// details.

CS_ChineseApp theApp;
4、并添加.def文件，用于导出.lib文件
; S_Chinese.def : Declares the module parameters for the DLL.
LIBRARY "S_Chinese"
DESCRIPTION 'S_Chinese Windows Dynamic Link Library'
EXPORTS
; Explicit exports can go here
5、编译得到S_Chinese.dll S_Chinese.lib文件，如果只是动态加载的话 ，只需要.dll文件
6、在Dlg项目中初始化对话框(Dlg.cpp文件)前面添加加载资源的句柄，如下所示
// Dlg.cpp : Defines the class behaviors for the application.
//
#include "stdafx.h"
#include "Dlg.h"
#include "DlgDlg.h"
#ifdef _DEBUG
#define new DEBUG_NEW
#undef THIS_FILE
static char THIS_FILE[] = __FILE__;
#endif

// DO NOT EDIT what you see in these blocks of generated code!
//}}AFX_MSG
ON_COMMAND(ID_HELP, CWinApp::OnHelp)
END_MESSAGE_MAP()
/////////////////////////////////////////////////////////////////////////////
// CDlgApp construction
CDlgApp::CDlgApp()
{
// TODO: add construction code here,
// Place all significant initialization in InitInstance
}
/////////////////////////////////////////////////////////////////////////////
// The one and only CDlgApp object
CDlgApp theApp;
/////////////////////////////////////////////////////////////////////////////
// CDlgApp initialization
BOOL CDlgApp::InitInstance()
{
AfxEnableControlContainer();
// Standard initialization
// If you are not using these features and wish to reduce the size
// of your final executable, you should remove from the following
// the specific initialization routines you do not need.
#ifdef _AFXDLL
Enable3dControls(); // Call this when using MFC in a shared DLL
#else
Enable3dControlsStatic(); // Call this when linking to MFC statically
#endif
HINSTANCE hInst;
hInst=LoadLibrary("S_Chinese.dll");
if(hInst!=NULL)
AfxSetResourceHandle(hInst);
CDlgDlg dlg;
m_pMainWnd = &dlg;
int nResponse = dlg.DoModal();
if (nResponse == IDOK)
{
// TODO: Place code here to handle when the dialog is
// dismissed with OK
}
else if (nResponse == IDCANCEL)
{
// TODO: Place code here to handle when the dialog is
// dismissed with Cancel
}
// Since the dialog has been closed, return FALSE so that we exit the
// application, rather than start the application's message pump.
return FALSE;
}
