HIGHCONTRAST
The HIGHCONTRAST structure contains information about the High Contrast Mode accessibility
feature, which sets the appearance scheme of the user interface for maximum
visibility for a visually-impaired user, and advises applications to comply with this
appearance scheme.
typedef struct tagHIGHCONTRAST { // hc
UINT cbSize;
DWORD dwFlags;
LPTSTR lpszDefaultScheme;
} HIGHCONTRAST, FAR* LPHIGHCONTRAST;
Members
cbSize
Specifies the size, in bytes, of this structure.
dwFlags
Specifies a combination of the following values:
Value
| Meaning
| HCF_AVAILABLE
| The High Contrast Mode is available.
| HCF_CONFIRMHOTKEY
| A confirmation dialog appears when the the High Contrast Mode is activated by
using the hot key.
| HCF_HIGHCONTRASTON
| The High Contrast Mode is on.
| HCF_HOTKEYACTIVE
| The user can turn the High Contrast Mode on and off by simultaneously pressing
the left ALT, left SHIFT, and PRINT SCREEN keys.
| HCF_HOTKEYAVAILABLE
| The hot key associated with the High Contrast Mode can be enabled. An
application can retrieve this value, but cannot set it.
| HCF_HOTKEYSOUND
| A siren is played when the user turns the High Contrast Mode on or off by
using the hot key.
| HCF_INDICATOR
| A visual indicator is displayed when the High Contrast Mode is on. This value
is not currently used and is ignored.
|
lpszDefaultScheme
Points to a string that contains the name of the default color scheme.
Remarks
An application uses this structure when calling the SystemParametersInfo function with the SPI_GETHIGHCONTRAST or SPI_SETHIGHCONTRAST value. When
using SPI_GETHIGHCONTRAST, an application must specify the cbSize member of the HIGHCONTRAST structure; the SystemParametersInfo function fills the remaining members. An application must specify all
structure members when using the SPI_SETHIGHCONTRAST value.

Nostalgia .Net |
|
.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More » |
