The Framework

Instead of creating an application using "raw" Win32 classes and functions, the MFC library simplifies this process by providing a mechanism called the framework. The framework is a set of classes, functions, and techniques used to create an application as complete as possible with as few lines of code as possible. To provide all this functionality, the framework works behind the scenes with the CWinApp class to gather the necessary MFC classes and functions, to recognize and reconcile the Win32 classes that the application needs. This reconciliation is also made possible by a set of global functions. These functions have names that start with Afx... Some of these functions are:
  • AfxFormatString1
  • AfxFormatString2
  • AfxMessageBox
  • AfxFreeLibrary
  • AfxGetApp
  • AfxGetAppName
  • AfxGetInstanceHandle
  • AfxGetMainWnd
  • AfxGetResourceHandle
  • AfxInitRichEdit
  • AfxLoadLibrary
  • AfxMessageBox
  • AfxRegisterWndClass
  • AfxSocketInit
  • AfxSetResourceHandle
  • AfxRegisterClass
  • AfxBeginThread
  • AfxEndThread
  • AfxGetThread
  • AfxWinInit
We will come back to some of these functions and we will see many other MFC macros in later lessons.

Adding Existing Files to a Project

If a file had already been created and exists on a separate folder, drive, directory or project, you can import it and add it to your application. When you decide to add an existing file to a project, because Microsoft Visual Studio allows you a great level of flexibility on the types of files you can add, it is your responsibility to check that the file is valid. If you copy a file from somewhere and paste it in the folder that contains your project, the file is still not considered as part of the project. You must explicitly add it. Before adding an existing file to your project: On the main menu, you can click File -> Add Existing Itemﾃδ｢ﾃ｢窶堋ｬﾃつｦ On the main menu, you can also click Project -> Add Existing Itemﾃδ｢ﾃ｢窶堋ｬﾃつｦ In the Solution Explorer, you can right-click the name of the project, position your mouse on Add and click Add Existing Itemﾃδ｢ﾃ｢窶堋ｬﾃつｦ Any of these actions would open the Add Existing Item dialog box. This requires you to locate the item and select it. O...

Introduction to Microsoft Visual C++/MFC

Microsoft Visual C++ is a programming environment used to create applications for the Microsoft Windows family of operating systems. To use these lessons, you must have installed either Microsoft Visual Studio 2010. Although Microsoft Visual Studio 2010 Professional provides many programming environments for the price of one, in our lessons, we will use it but we will cover only the Microsoft Foundation Class (MFC) library side. After installing it, to use the programming environment, you must first open it. To do that, you would click Start -> (All) Programs -> Microsoft Visual Studio 2010 -> Microsoft Visual Studio 2010. In our lessons, unless used in code, the -> arrow means an action that should follow another. Based on this: Edit -> Copy means click Edit, then click Copy View -> Toolbars -> Custom means click View position the mouse on Toolbars, and then click Custom To start Microsoft Visual C++ or Visual Studio, on the Taskbar, click Start (All) Prog...

Creating a File

Although the most popular files used in Microsoft Visual C++ are header and source files, this IDE allows you to create various other types of files that are not natively C++ types. To create a file, if a project is currently opened: On the main menu, click Project -> Add New Item... This would open the New dialog box from where you can select the desired type of file and click Open. By default, the new file would open in the Source Code Editor. If you want to open the file otherwise, after selecting it in the New dialog box, click the arrow of the Open As combo box. In the Solution Explorer or the Class View, right- click the name of the project, position the mouse of Add, and click the option you want
