Introduction

Shows how to create a very simple MFC Direct2D application, or how to convert an existing MFC application to Direct2D.

This code is the illustration of this blog article: MFC and Direct2D, part 1/N

Building the Sample

To build this sample, open the solution (.sln) file titled Helloworld.sln (C++ project)  from Visual Studio 2010 SP1 (any SKU). Press F7 or go to Build->Build Solution from the top menu after the sample has loaded.

The Service Pack 1 for Visual Studio 2010 is required.

The blog article shows how to convert an MFC application which uses GDI to a Direct2D MFC application, and focuses on explaining how the things work under the hood.

The code sample uses a simple MFC AppWizard generated application. Only the code of the View is modified (file HelloWorldApp.cpp / .h)

    m_pTextFormat->Get()->SetParagraphAlignment(DWRITE_PARAGRAPH_ALIGNMENT_CENTER);

    // Draw text 
    CRect rect; 
    GetClientRect(rect); 
    pRenderTarget->DrawText(_T("Hello, World!"), rect, m_pBlueBrush, m_pTextFormat); 
    return TRUE;
