Visual Studio 2015 MFC Programming Tutorial for Beginners18

Microsoft Foundation Classes (MFC) is a library developed by Microsoft that provides a set of C++ classes that encapsulate the Windows API. MFC simplifies the development of Windows applications by providing a high-level interface to the underlying operating system. This tutorial will guide you through the basics of MFC programming using Visual Studio 2015.

Creating a New MFC Application

1. Open Visual Studio 2015 and click on "File" -> "New" -> "Project".
2. In the "New Project" dialog box, select the "Visual C++" template and then select the "MFC Application" project type.
3. Enter a name for your project and click on the "OK" button.

Understanding the MFC Application Structure

The MFC application structure is divided into two main parts: the user interface (UI) and the application logic. The UI is created using MFC classes such as CDialog, CFrameWnd, and CWnd. The application logic is implemented in the member functions of these classes.

Creating a Dialog Box

A dialog box is a modal window that is used to interact with the user. To create a dialog box, you can use the Class Wizard.
1. Right-click on the "Resource View" tab in the Solution Explorer and select "Insert" -> "Dialog".
2. In the "Insert Dialog" dialog box, enter a name for your dialog box and click on the "OK" button.

Adding Controls to the Dialog Box

Controls are used to add functionality to a dialog box. To add controls to a dialog box, you can use the Toolbox.
1. Drag and drop the desired controls from the Toolbox onto the dialog box.

Handling Events

Events are triggered when the user interacts with a control. To handle events, you can override the corresponding event handler function in the dialog box class.
1. Right-click on the control in the dialog box and select "Event Handlers".
2. In the "Event Handlers" dialog box, select the event you want to handle and click on the "Add" button.

Writing Code in the Event Handler

In the event handler function, you can write code to respond to the event. For example, you can use the following code to handle the OnBnClicked() event of a button:```cpp
void CMyDialog::OnBnClickedButton1()
{
MessageBox(L"Button 1 was clicked", L"Information", MB_OK);
}
```

Building and Running the Application

Once you have written the code, you can build and run the application.
1. Click on the "Build" -> "Build Solution" menu item.
2. If the build is successful, click on the "Debug" -> "Start Debugging" menu item.

Conclusion

This tutorial has provided you with a basic understanding of MFC programming using Visual Studio 2015. You have learned how to create a new MFC application, add controls to a dialog box, handle events, and write code in the event handler. With this knowledge, you can start developing your own MFC applications.
