Change Font Type and Size
You can change font type, size of style of a dialog box's controls by writing few lines of code.
Sample Code:
Write this code OnInitDialog of your application.
LOGFONT lf; // Used to create the CFont.
memset(&lf, 0, sizeof(LOGFONT)); // Clear out structure.
lf.lfHeight = 20; // Request a 20-pixel-high font
lf.lfWeight = FW_BOLD ;
strcpy(lf.lfFaceName, "Arial"); // with face name "Arial".
m_font.CreateFontIndirect(&lf); // Create the font.
// Use the font to paint a control. This code assumes
// a control named IDC_TEXT1 in the dialog box.
GetDlgItem(IDC_EDIT1)->SetFont(&m_font);
GetDlgItem(IDC_BROWSE)->SetFont(&m_font);
GetDlgItem(IDOK)->SetFont(&m_font);
GetDlgItem(IDCANCEL)->SetFont(&m_font);
