Visual C++ 2010: MFC new features<\/h2>\n

Some years ago i thought that MFC will be obsolete, and no new features will be added, but i was wrong, VS2008 added many features and functionalities, and with VS 2010 i discovered new improvements.<\/p>\n

So what’s new in MFC 10?
\nTo answer to this question i tried to compare the two versions MFC 8 and MFC 10 using CppDepend.<\/p>\n

Removed classes<\/h2>\n

Let’s begin with breaking changes and search for removed classes:<\/p>\n

SELECT TYPES WHERE<\/span> WasRemoved<\/p>\n

\"\"<\/p>\n

It was very strange that this class is removed , and to be sure i searched in the code source and i found it inside #ifdef ENABLE_RIBBON_LAUNCH_BUTTON statement.<\/p>\n

The only resource i found in the web talking about this change is here , and i dont know if adding #define ENABLE_RIBBON_LAUNCH_BUTTON is suficient to compile without problem.<\/p>\n

Added Classes<\/h2>\n

SELECT TYPES WHERE<\/span> WasAdded AND <\/span>isClass<\/p>\n

\"\"<\/p>\n

What’s the new features added by these classes?<\/strong>
\n
\nCMFCRibbonCollector, CMFCRibbonConstructor, CMFCRibbonInfo: <\/strong>
\nWhen i searched in MSDN the utility of these classes , i didnt found any useful informations, so i searched for methods using CMFCRibbonInfo.<\/p>\n

SELECT METHODS WHERE<\/span> IsDirectlyUsing “CMFCRibbonInfo<\/span>”<\/p>\n

\"\"<\/p>\n

The RibbonBar class use CMFCRibbonInfo to save it to xml or load it.<\/p>\n

CJumpList, CAppDestinations:<\/strong><\/p>\n

Jump list is a new useful Window7 feature, it adds a new way of interaction between user and application.
\nhere’s a good article to add JumpList feature with MFC.<\/p>\n

CDataRecoveryHandler:<\/strong><\/p>\n

This class autosaves documents and restores them if an application unexpectedly exits, it’s used by Restart Manager feature, here’s an interesting article talking about it.<\/p>\n

Let’s search for classes used by CDataRecoveryHandler:<\/p>\n

SELECT TYPES WHERE<\/span> IsDirectlyUsedBy “CDataRecoveryHandler<\/span>”<\/p>\n

\"\"<\/p>\n

CDataRecoveryHandler is highly coupled with other MFC classes like CDocument, CWinApp, CWnd.<\/p>\n


\nWhich MFC classes use the recovery feature?<\/strong><\/p>\n

SELECT TYPES WHERE<\/span> IsDirectlyUsing “CDataRecoveryHandler<\/span>”<\/p>\n

\"\"<\/p>\n

So all these classes benefit of this new feature especially CDocument.<\/p>\n

CTaskDialog:
\nA pop-up dialog box that functions like a message box but can display additional information to the user.<\/p>\n

here’s an interesting article talking about this feature.<\/p>\n


\nCMFCVisualManagerVS2008, CMFCVisualManagerWindows7: <\/strong>
\nGives an application the appearance of a VS2008 or Windows 7 application.<\/p>\n


\nCGestureConfig: <\/strong>
\nUsed for touch feature.<\/p>\n


\nCFolderPickerDialog: <\/strong>
\nCFolderPickerDialog class implements CFileDialog in the folder picker mode.<\/p>\n


\nCXMLParser, CXMLParserCollection, CXMLParserRoot: <\/strong>
\nWhen i discovered these classes, i thought that is concerning xml parsing but when i searched for methods using them i discovered that only CMFCRibbonInfo use them to save or load its description to xml files.<\/p>\n

SELECT METHODS WHERE<\/span> IsDirectlyUsing “CXMLParserRoot<\/span>”<\/p>\n

\"\"<\/p>\n

CMFCZoomKernel, CMFCScanliner, CMFCScanlinerBitmap:<\/strong>
\nNot yet documented in MSDN, let’s discover which classes use them.<\/p>\n

SELECT TYPES WHERE<\/span> IsDirectlyUsing “CMFCZoomKernel<\/span>”<\/p>\n

\"\"<\/p>\n

And we have the same result for the two other classes.<\/p>\n

SafeInt classes:<\/strong>
\nExtends the integer primitives to help prevent integer overflow and lets you compare different types of integers.
\nhere’s a video about using SafeInt.<\/p>\n

After detecting which classes are added and removed, let’s discover all methods removed or added to MFC10, and which features are implemented by these methods.<\/p>\n

Methods Removed<\/h2>\n

SELECT METHODS WHERE<\/span> WasRemoved<\/p>\n

\"\"<\/p>\n

Almost all theses methods are not removed but only the signature is changed , and some optional parameters are added, however some methods are removed like CCommandManager::ResetAllImages or CPanelDialog::ClipPaint, and one method was renamed from CMFCRibbonBar::GetTabTrancateRatio to CMFCRibbonBar::GetTabTruncateRatio.<\/p>\n

Methods Added<\/h2>\n

Let’s search for all methods added to MFC10<\/p>\n

SELECT METHODS WHERE<\/span> WasAdded<\/p>\n

\"\"<\/p>\n

Which features are added by these new methods?<\/strong><\/p>\n

For that we will focus only in the most used classes.<\/p>\n

CWnd:<\/strong>
\nHere’s the methods added for CWnd, and almost all methods added concern touch feature and touch gestures.<\/p>\n

\"\"<\/p>\n

CFile, CStdioFile, CFileFind: <\/strong>
\nMany methods of these classes add CAtlTransactionmanager as optional parameter.<\/p>\n

Transactional File System is a new technology first introduced in Windows Vista. It enables you to roll back operations made on the file system and registry.<\/p>\n

Here’s a good article about this feature.<\/p>\n

CRecentFileList:<\/strong><\/p>\n

\"\"<\/p>\n

New possibilities to add item to recent file list are now available.<\/p>\n

CDocument:<\/strong> Here’s the methods added by CDocument:<\/p>\n

\"\"<\/p>\n

Two new features concern methods added : Supporting Windows Search with MFC<\/strong> and Rich Preview<\/strong> <\/p>\n

Let’s discover the changes concerning dependency of CDocument to other MFC classes,and which additional dependencies are added in MFC10, for that Dependency Matrix can be useful, and the sign “+” in the cell representing the dependency indicate that this dependency is new.<\/p>\n

\"\"<\/p>\n

So many dependencies are added, especially with new classes added to MFC10 like CDataRecoveryHandler,and also some other inner classes added to CDocument.<\/p>\n

CFileDialog:<\/strong> Here’s the methods added by CFileDialog:<\/p>\n

\"\"<\/p>\n

A good news is we can now customize CFileDialog by adding what we want in the dialog.<\/p>\n

CMDIChildWndEx:<\/strong>
\nHere’s the methods added by CMDIChildWndEx<\/p>\n

\"\"<\/p>\n

Windows7 add a new interesting features like:taskbar Tabs,Taskbar thumbnails and thumbnail previews, and almost all methods added to CMDIChildWndEx concern theses features.<\/p>\n

CFrameWnd:<\/strong>
\nWindows 7 add also some useful features like OverlayIcon and progressbar in the taskbar, and the methods added to CFrameWnd concern these features.<\/p>\n

\"\"<\/p>\n

CWinApp:<\/strong>
\nAlmost all methods added to CWinApp concern the ApplicationRecovery support.<\/p>\n

\"\"<\/p>\n

Other useful methods are added like CMFCControlRenderer::SmoothResize and CDrawingmanager::DrawRotated.<\/p>\n

Methods where visibility was changed<\/h2>\n

SELECT METHODS WHERE<\/span> VisibilityWasChanged<\/p>\n

\"\"<\/p>\n

Almost the visibility of all CMFCRibbonTab methods is changed from private to public.<\/p>\n

But when i checked the code source the only modification in the class declaration is the adding of DECLARE_DYNAMIC(CMFCRibbonTab) , this macro include “public:” , so i wonder if this visibility changes is only a side effect of adding this macro.<\/p>\n","protected":false},"excerpt":{"rendered":"
