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

// CDlgApp:

Dlg.cpp 

// Dlg.cpp : Defines the class behaviors for the application.
//

#include "stdafx.h"
#include "Dlg.h"
#include "DlgDlg.h"

#ifdef _DEBUG
#define new DEBUG_NEW

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

/////////////////////////////////////////////////////////////////////////////
// CDlgApp construction

}

/////////////////////////////////////////////////////////////////////////////

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;
}

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_

#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

/////////////////////////////////////////////////////////////////////////////
// CS_ChineseApp
// See S_Chinese.cpp for the implementation of this class
//

class CS_ChineseApp : public CWinApp
{
public:
	CS_ChineseApp();

// Overrides
	// ClassWizard generated virtual function overrides
	//{{AFX_VIRTUAL(CS_ChineseApp)
	//}}AFX_VIRTUAL

	//{{AFX_MSG(CS_ChineseApp)
		// NOTE - the ClassWizard will add and remove member functions here.
		//    DO NOT EDIT what you see in these blocks of generated code !
	//}}AFX_MSG
	DECLARE_MESSAGE_MAP()
};


/////////////////////////////////////////////////////////////////////////////

//{{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.

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

/////////////////////////////////////////////////////////////////////////////
// CDlgApp

BEGIN_MESSAGE_MAP(CDlgApp, CWinApp)
	//{{AFX_MSG_MAP(CDlgApp)
		// NOTE - the ClassWizard will add and remove mapping macros here.
		//    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;
}

到这里便完成了多语言系统的制作，例子代码如下 http://download.csdn.net/detail/wangweitingaabbcc/4578441
