MFC implementation resources are implemented separately by DLL

summary

We are developing MFC In the project , If it's a project, it's ok , If we divide into different projects , And each project as Dll Provide , In this way, resources may be stored in each dynamic library , Very bad for management , So we think of resources as a single Dll Library provides .

resources Dll The implementation of the

Create resources Dll

Compile after creation , After compiling , It means that our project is OK , There is also a link option to set

Now we can add our own resources 、 Edit resource .

The call of the main program sets the resource dynamic library .

// CMultilingualDemoApp  initialization 

BOOL CMultilingualDemoApp::InitInstance()
{
    
	//  If one runs on  Windows XP  The application manifest on specifies to 
	//  Use  ComCtl32.dll  edition  6  Or later to enable visualization ,
	// You need to  InitCommonControlsEx().  otherwise , Windows will not be created .
	INITCOMMONCONTROLSEX InitCtrls;
	InitCtrls.dwSize = sizeof(InitCtrls);
	//  Set it to include all of the 
	//  Common control classes .
	InitCtrls.dwICC = ICC_WIN95_CLASSES;
	InitCommonControlsEx(&InitCtrls);

	CWinApp::InitInstance();
	m_hLangDLL = NULL;


	AfxEnableControlContainer();

	//  establish  shell  Manager , In case the dialog box contains 
	//  whatever  shell  Tree view control or  shell  List view control .
	CShellManager *pShellManager = new CShellManager;

	//  Activate “Windows Native” Vision Manager , In order to be in  MFC  Control 
	CMFCVisualManager::SetDefaultManager(RUNTIME_CLASS(CMFCVisualManagerWindows));

	//  Standard initialization 
	//  If you don't use these features and want to reduce 
	//  The size of the final executable , The following should be removed 
	//  Specific initialization routines not required 
	//  Change the registry key used to store settings 
	// TODO:  The string should be modified appropriately ,
	//  For example, change it to company or organization name 
	SetRegistryKey(_T(" Local applications generated by the application wizard "));


	HINSTANCE m_hLangDLL = ::LoadLibrary(_T("Resource_zh.dll"));

	if(m_hLangDLL != NULL)
	{
    
		AfxSetResourceHandle(m_hLangDLL);
	}
	else
	{
    
		AfxMessageBox(_T(" resources DLL File load failed ！"));
	   exit(1);
	}

In fact, the implementation of resource independent dynamic library is realized .

Digression ：

Resources are used alone as Dll Can succeed , So if we are multilingual , Each language can be a separate Dll, In this way, the use of Dll Multi language support .
The following is the code for dynamically loading resources ：

BOOL CMultilingualDemoDlg::ResetDialog()
{
    
    //TODO:  Process additional resources that may have been added 
    AfxOleTerm(FALSE);

    if(m_hLangDLL)
    {
    
        FreeLibrary(m_hLangDLL);
    }

    STARTUPINFO StartupInfo={
    0};
    PROCESS_INFORMATION ProcessInfo;

    StartupInfo.cb=sizeof(STARTUPINFO);
    char Path[256];
    GetModuleFileName(NULL,(LPSTR)(LPCTSTR)Path,255);
    CreateProcess(NULL,(LPSTR)(LPCTSTR)Path,NULL,NULL,FALSE,0,NULL,NULL,&StartupInfo,&ProcessInfo);
    return TRUE;
}
