怎么把系统时间输入到DateTimePicker中。

[ye83241905]

我用Ctime类获得时间以后，怎么加到DateTimePicker控件中呢？麻烦说得详细点。

[newzk]

CTime t = CTime::GetCurrentTime();
UpdateData(FALSE);

[newzk]

CDateTimeCtrl::SetTime
BOOL SetTime( const COleDateTime& timeNew );

BOOL SetTime( const CTime* pTimeNew );

BOOL SetTime( LPSYSTEMTIME pTimeNew = NULL );

Return Value

Nonzero if successful; otherwise 0.

Parameters

timeNew

A reference to a COleDateTime object containing the to which the control will be set.

pTimeNew

In the second version above, a pointer to a CTime object containing the time to which the control will be set. In the third version above, a pointer to aSYSTEMTIME structure containing the time to which the control will be set.

Remarks

This member function implements the behavior of the Win32 messageDTM_SETSYSTEMTIME, as described in the Platform SDK.

In the MFC implementation of SetTime, you can use the COleDateTime or CTime classes, or you can use a SYSTEMTIME structure, to set the time information.

能不能在细点。t = GetCurrentTime();以后，怎么加到DateTimePicker中去，并显示出来。

[newzk]

CTime t = CTime::GetCurrentTime();
((CDateTimeCtrl*)GetDlgItem(IDC_DATETIMEPICKER))->SetTime(&t);

[newzk]

够细了吧

[ye83241905]

多谢。
CTime t；
t.GetCurrentTime();
((CDateTimeCtrl*)GetDlgItem(IDC_DATETIMEPICKER))->SetTime(&t);
这样没什么问题吧。
CDateTimeCtrl指该控件型变量，*号一定要加吗？IDC_DATETIMEPICKER指该变量的IDC号。
初学者，别嫌麻烦？请指正。怎么编译老说括号有问题呢？

[newzk]

已运行过了，估计是你眼花了，打错了。

IDC_DATETIMEPICKER 是我窗体上date and time picker control的ID，你的我就不知道了;-)。

A CDateTimeCtrl object encapsulates the functionality of a date and time picker control. The date and time picker control (DTP control) provides a simple interface to exchange date and time information with a user. This interface contains fields, each of which displays a part of the date and time information stored in the control. The user can change the information stored in the control by changing the content of the string in a given field. The user can move from field to field using the mouse or the keyboard.

You can customize the date and time picker control by applying a variety of styles to the object when you create it. SeeDate and Time Picker Control Styles in the Platform SDK for more information about styles specific to the date and time picker control. You can set the display format of the DTP control using format styles. These format styles are described inPreset DTP Display Formats in the Platform SDK.

谢谢！我把前面的CDateTimeCtrl当成变量了。编译已无问题。只是取出来的时间不对呀。没有规律的乱变。

[newzk]

取的时间是你得系统时间，不变才怪

[ye83241905]

可是它是没规律的乱变呀。不是电脑显示的时间。
