SftMask/DLL 7.0 - Masked Edit Control

SetHighContrastMode

void SftMask_SetHighContrastMode(HWND hwndCtl, int mode);

C++

void CSftMask::SetHighContrastMode(int mode);

hwndCtl

The window handle of the masked edit control.

mode

The high contrast setting. One of the following values:

SFTMASK_HIGHCONTRAST_OFF	Ignore the Windows High Contrast setting and render normally. Not recommended in shipping applications.
SFTMASK_HIGHCONTRAST_ON	Always use the system palette, regardless of the Windows High Contrast setting.
SFTMASK_HIGHCONTRAST_AUTO	Follow the Windows High Contrast setting. The control re-renders when the setting flips. This is the default.

While high contrast is active, system color values resolve to the user's high contrast palette, dark mode rendering is suppressed and Windows themes are suppressed - this covers the edit area, caption, popup calendar, popup calculator and autocomplete window. Custom RGB color values set by the application remain in effect. See High Contrast.

When the mode is SFTMASK_HIGHCONTRAST_AUTO, the control sends SFTMASKN_HIGHCONTRAST_CHANGED to its parent window each time the active state flips.

The high contrast setting can also be set through the nHighContrastMode field of the SFTMASK_CONTROL structure.
