    DWORD dwFlags,
    int nGlowSize = 0,
    COLORREF clrText = (COLORREF)-1);

Parameters

hTheme
[in] Handle to the theme data of a window, or NULL. The framework uses the specified theme to draw the text if this parameter is not NULL and themes are supported. Otherwise, the framework does not use a theme to draw the text.

Use the OpenThemeData method to create an HTHEME.

pDC
[in] Pointer to a device context.

iPartId
[in] The control part that has the desired text appearance. For more information, see the Parts column of the table in Parts and States. If this value is 0, the text is drawn in the default font, or a font selected into the device context.

iStateId
[in] The control state that has the desired text appearance. For more information, see the States column of the table in Parts and States.

strText
[in] The text to draw.

rect
[in] The boundary of the area in which the specified text is drawn.

dwFlags
[in] A bitwise combination (OR) of flags that specify how the specified text is drawn.

If the hTheme parameter is NULL or if themes are not supported and enabled, the nFormat parameter of the CDC::DrawText method describes the valid flags. If themes are supported, the dwFlags parameter of the DrawThemeTextEx method describes the valid flags.

clrText
[in] The color in which the specified text is drawn. The default value is the default color.

Return Value

TRUE if a theme is used to draw the specified text; otherwise, FALSE.

Remarks

A theme defines the visual style of an application. A theme is not used to draw the text if the hTheme parameter is NULL, or if the DrawThemeTextEx method is not supported, or if Desktop Window Manager (DWM) composition is disabled.

AFX_GLOBAL_DATA::EnableAccessibilitySupport

Enables or disables Microsoft Active Accessibility support.

void EnableAccessibilitySupport(BOOL bEnable=TRUE);

Parameters

bEnable
[in] TRUE to enable accessibility support; FALSE to disable accessibility support. The default value is TRUE.

Remarks

Active Accessibility is a COM-based technology that improves the way programs and the Windows operating system work together with assistive technology products. It provides reliable methods for exposing information about user interface elements. However, a newer accessibility model called Microsoft UI Automation is now available. For a comparison of the two technologies, see UI Automation and Microsoft Active Accessibility.

Use the AFX_GLOBAL_DATA::IsAccessibilitySupport method to determine whether Microsoft Active Accessibility support is enabled.

AFX_GLOBAL_DATA::ExcludeTag

Removes the specified XML tag pair from a specified buffer.

BOOL ExcludeTag(
    CString& strBuffer,
    LPCTSTR lpszTag,
    CString& strTag,
    BOOL bIsCharsList = FALSE);

Parameters

strBuffer
[in] A buffer of text.

lpszTag
[in] The name of a pair of opening and closing XML tags.

strTag
[out] When this method returns, the strTag parameter contains the text that is between the opening and closing XML tags that are named by the lpszTag parameter. Any leading or trailing whitespace is trimmed from the result.

bIsCharsList
[in] TRUE to convert symbols for escape characters in the strTag parameter into actual escape characters; FALSE not to perform the conversion.The default value is FALSE. For more information, see Remarks.

Return Value

TRUE if this method is successful; otherwise, FALSE.

Remarks

An XML tag pair consists of named opening and closing tags that indicate the start and end of a run of text in the specified buffer. The strBuffer parameter specifies the buffer, and the lpszTag parameter specifies the name of the XML tags.

Use the symbols in the following table to encode a set of escape characters in the specified buffer. Specify TRUE for the bIsCharsList parameter to convert the symbols in the strTag parameter into actual escape characters. The following table uses the _T() macro to specify the symbol and escape character strings.

Symbol Escape character
_T("\\t") _T("\t")
_T("\\n") _T("\n")
_T("\\r") _T("\r")
_T("\\b") _T("\b")
_T("LT") _T("<")
_T("GT") _T(">")
_T("AMP") _T("&")

AFX_GLOBAL_DATA::GetColor

Return Value

The RGB color value of the specified user interface element. For more information, see Remarks.

Remarks

If the nColor parameter is out of range, the return value is zero. Because zero is also a valid RGB value, you cannot use this method to determine whether a system color is supported by the current operating system. Instead, use the GetSysColorBrush method, which returns NULL if the color is not supported.
