I have update the MFC static control presented in the previous articles by adding methods for setting text range color, typography and inline images.
Code samples

void CDemoDlg::_DoDemo_Effects() { m_staticDemo.Clear(); const CString strTagRed = _T("RED"); const CString strTagGreen = _T("GREEN"); const CString strTagBlue = _T("BLUE"); CString strText; strText.Format(_T("IDWriteTextLayout::SetDrawingEffect can change the color") _T(" of a text range as for example: \n\t%s\n\t%s\n\t%s"), strTagRed, strTagGreen, strTagBlue); m_staticDemo.SetText(strText); // set text range colors m_staticDemo.SetTextColor(strText.Find(strTagRed), strTagRed.GetLength(), RGB(255,0,0)); m_staticDemo.SetTextColor(strText.Find(strTagGreen), strTagGreen.GetLength(), RGB(0, 255, 0)); m_staticDemo.SetTextColor(strText.Find(strTagBlue), strTagBlue.GetLength(), RGB(0, 0, 255)); } |

Is AFX_WM_RECREATED2DRESOURCES handler really neccesary in any circumstances? It wasn’t mentioned in your MFC Direct2d tutorial.
Usually there is no much to do. See this article:

Thank you so much for the explanation about the issue.
