CMonthCalCtrl::SetDayState
将显示在月历控件的日。
BOOL SetDayState(
int nMonths,
LPMONTHDAYSTATE pStates
);
参数
nMonths
值指示某个元素在 pStates 指向的数组。pStates
用于定义的 MONTHDAYSTATE 的指针值month calendar控件在其显示每天将绘制。 MONTHDAYSTATE 数据类型是位域,每位(1到31)在一个月份表示一天状态。 如果位打开,对应的日以粗体显示;否则它将显示没有焦点。
返回值
非零,如果成功;否则为0。
备注
此成员函数实现Win32消息 MCM_SETDAYSTATE的行为,如 Windows SDK所述。
示例
void CMonthCalDlg::OnBnClickedDaystatebutton()
{
// First, we must find the visible range. The array we pass to the
// SetDayState() function must be large enough to hold days for all
// of the visible months. Even if a month is _partially_ visible,
// we must have MONTHDAYSTATE data for it in the array we pass.
// GetMonthRange() returns the range of days currently visible in
// the control, along with a count of visible months. This array
// will be up to 2 months larger than the number of "pages" visible
// in the control.
SYSTEMTIME timeFrom;
SYSTEMTIME timeUntil;
int nCount = m_calCtrl1.GetMonthRange(&timeFrom, &timeUntil, GMR_DAYSTATE);
// Allocate the state array based on the return value.
LPMONTHDAYSTATE pDayState;
pDayState = new MONTHDAYSTATE[nCount];
memset(pDayState, 0, sizeof(MONTHDAYSTATE) * nCount);
// Find the first fully visible month.
int nIndex = (timeFrom.wDay == 1) ? 0 : 1;
// Set the 4th day, 19th day, and 26th day of the first
// _fully_ visible month as bold.
pDayState[nIndex] |= 1 << 3; // 4th day
pDayState[nIndex] |= 1 << 18; // 19th day
pDayState[nIndex] |= 1 << 25; // 25th day
// Set state and clean up
VERIFY(m_calCtrl1.SetDayState(nCount, pDayState));
delete [] pDayState;
}
