COleDateTime cdt1;
CString chk_dt1=cdt1.Format(_T("%d %b, %Y %I:%M:%S %p"));

You didn't initialize cdt1. You need to use one of the COleDateTime constructors that initializes it, or use this:

cdt1 = COleDateTime::GetCurrentTime();

before calling cdt1.Format().

i cant use this,

Hans Dietrich wrote:

coz its not confirm ,the date time control have current data time,

user can select any date time and i perform action according to selected dates.

when i debug the program i found problem arise on ParseDateTime.

Here is the code you posted:

COleDateTime cdt1;
CString chk_dt1=cdt1.Format(_T("%d %b, %Y %I:%M:%S %p"));
cdt1.ParseDateTime(chk_dt1,0,LANG_USER_DEFAULT);

Please tell me where in this code you initialize cdt1 to some valid date value.

Best wishes,
Hans

its actually this.

CString from_date,to_date;
	GetDlgItemText(IDC_DATETIMEPICKER1,from_date);
	GetDlgItemText(IDC_DATETIMEPICKER2,to_date);
	
	cdt1.ParseDateTime(from_date,0,LANG_USER_DEFAULT);
	cdt2.ParseDateTime(to_date,0,LANG_USER_DEFAULT);

	CString chk_dt1=cdt1.Format(_T("%d %b, %Y %I:%M:%S %p"));
	CString chk_dt2=cdt2.Format(_T("%d %b, %Y %I:%M:%S %p"));
	
	cdt1.ParseDateTime(chk_dt1,0,LANG_USER_DEFAULT);
	cdt2.ParseDateTime(chk_dt2,0,LANG_USER_DEFAULT);

A datetime picker holds a date/time value, not a string. Why on earth are you calling GetDlgItemText() on it and then parsing the outcome? Have a look here[^].

Don't use strings when there is a more appropriate type around.

I provided a link to an example based on GetTime(). If you don't like it, google for some more examples. I don't have any myself.

in this link example use only get time there is no option where assign value in COleDateTime type variable.

here only get time from control and set the text in edit box.

please understand my problem and help me to resolve this.

Have you tried:

COleDateTime DateTime;
((CDateTimeCtrl *) GetDlgItem(IDC_DATETIMEPICKER1))->GetTime(DateTime);

So use the appropriate cast, or better yet, a member variable. GetDlgItem() is to be used sparingly.

Disable turning the screen off

Hello

I would like to disable the outomatic turning off the screen,
i.e. I want that the screen will always be on.

I need that the project will be suitable also to windows xp accordingly,
I can't use the function "RegisterPowerSettingNotification " .

If anyone know another way to do it I would be glad if he can write it to me.

thanks

You can use SystemParametersInfo() with the SPI_SETSCREENSAVEACTIVE parameter to control the screensaver. You may also need to use the same API with the SPI_SETPOWEROFFACTIVE parameter.

Best wishes,
Hans

Sounds like you need to notify someone of something important? I'm not always looking at a screen, and sometimes we even turn off the physical monitor.

Now, if something is amiss, the machine starts beeping, and will keep beeping until someone goes check on it - beep was chosen because it's hooked to the internal speaker, and doesn't rely on the availability of a sound-card Smile | :)

In general, messing up the user settings of a system from an application is not a good idea.

If the system is not used for that sole purpose, the user may have good reasons you cannot even imagine to keep the screen off (sometimes I even switch off the physical monitor!). By forcing it to be always on you're forcing a user system-requirement.
Try thinking a user that uses your application and another one that -for reasons opposite to yours- want to force it off. What a mess!

If the system is instead dedicated to your application (it will be in use for that only purpose ...) why not just configure it to have th screen always on, independently on your code?
