OK. I get it now. Have you tried the DateTime_SetSystemtime macro?

Thanks Rajesh..
SystemTime Works... Manage to manipulate day of week...
But how to print the changed day in DateTimePicker??
I mean if today is tuesday i can change it to wednesday with the help of
SYSTEMTIME st;
GetSystemTime(&st);
st.wDayofWeek += 1;
After that it increment the day. But when i try to print the result on DateTimePicker using DTM_SETFORMAT it doesn't reflect...
What could be the problem??
Ash..

And when i apply the code below on button click it changes time only not day of week. Also i'm not doing manipulating time as well..
Case IDC_BUTTON1:
{
st.wDayOfWeek += 1;
BOOL a =DateTime_SetSystemtime(GetDlgItem(hdlg,IDC_DATETIMEPICKER6),GDT_VALID, &st);
TCHAR lpszFormat3[MAX_PATH] = "hh':'mm 'every' dddd";
SendMessage(GetDlgItem(hdlg,IDC_DATETIMEPICKER6),DTM_SETFORMAT,(WPARAM) wParam,(LPARAM) (LPCTSTR) lpszFormat3);
}

Please try this code and tell me if it helped.
void NextDayOfWeek(const SYSTEMTIME& st, SYSTEMTIME *calculatedTime)
{
FILETIME ft;
SystemTimeToFileTime(&st, &ft);
ULARGE_INTEGER nenoSeconds, nenoseconds_in_a_day;;
nenoseconds_in_a_day.QuadPart = 24*60*60*1000;
nenoseconds_in_a_day.QuadPart *= 10000;
nenoSeconds.HighPart= ft.dwHighDateTime;
nenoSeconds.LowPart= ft.dwLowDateTime;
nenoSeconds.QuadPart += nenoseconds_in_a_day.QuadPart;
ft.dwHighDateTime = nenoSeconds.HighPart;
ft.dwLowDateTime = nenoSeconds.LowPart;
FileTimeToSystemTime(&ft, calculatedTime);
}
case IDC_BUTTON1:
{
SYSTEMTIME myTime, ans;
HWND hdt;
GetDlgItem(IDC_DATETIMEPICKER6, &hdt);
if(DateTime_GetSystemtime(hdt, &myTime) == GDT_VALID)
{
NextDayOfWeek(myTime, &ans);
::SendMessage(hdt, (UINT)DTM_SETSYSTEMTIME, (WPARAM)(DWORD)GDT_VALID, (LPARAM)(LPSYSTEMTIME)&ans);
}
}
I'd also suggest you read a little bit about FILETIME on MSDN.

Hi..
Thanks Rajesh...Code works..
Thanks a ton...
I'm actually new in this...Anyways you mind telling me the calculation?
I mean i'm bit confused in quadpart, Lowpart, Highpart..
Gone through MSDN but still confused...
How did you calculate the next day.
Thanks Again..
Ash..

To manipulate time as a long integer, we need to convert it to FILETIME. ULARGE_INTEGER[^] is an union, defined in Winnt.h. This data structure can store a 64 bit unsigned integer. This data structure has a Low part (the low order 32 bits) and a High part (the high order 32 bits), whereas the Quadpart will be the unsigned 64 bit integer itself. I take up the high and low order bits from the SYSTEMTIME variable passed on to this function and assign it to the ULARGE_INTEGER variable. And then I calculate the no. of nano seconds in a day (24 hours, 60 minutes, 60 seconds, 1000 milliseconds, 10000 nanoseconds). Then, I add it up to the Quadpart of the ULARGE_INTEGER variable, nenoSeconds. This way, we've incremented one day of the week. Assign it back to SYSTEMTIME variable, and convert it back to SYSTEMTIME from FILETIME. Look at the code simultaneously and you will understand it.

Alright Cool...
Got it..
One more problem..I'm using property sheet for tab control..There are 3 tabs(Property pages) in my property sheet..
How can position my property sheet at the center of the screen. I tried with SetWindowPos but couldn't succeed..Cause i'm not sure about the handle of propertysheet.
Can you help me in that??
Ash..

Can you show me the code? What do you mean you aren't sure about the handle?
Also, have you tried enabling the "Center" property of the dialog (at design time) which contains the property sheet? Also look at CWnd::CenterWindow()
In the future, if you have a new problem, please start a new thread.

Also it's Non-MFC..
Here's my code for creating the sheet..
Should i start new thread??
HWND CreatePropSheet()
{
PROPSHEETPAGE psp[4];
PROPSHEETHEADER psh;
memset(psp, 0, sizeof(PROPSHEETPAGE) * 4);
memset(&psh, 0, sizeof(PROPSHEETHEADER));
psp[0].dwSize = sizeof(PROPSHEETPAGE);
psp[0].dwFlags = PSP_USETITLE;
psp[0].hInstance = NULL;
psp[0].pszTemplate = MAKEINTRESOURCE(IDD_PROPPAGE_MEDIUM);
psp[0].pszIcon = NULL;
psp[0].pfnDlgProc = (DLGPROC)Page1DlgProc;
psp[0].pszTitle = TEXT("Job");
psp[1].dwSize = sizeof(PROPSHEETPAGE);
psp[1].dwFlags = PSP_USETITLE;
psp[1].hInstance = NULL;
psp[1].pszTemplate = MAKEINTRESOURCE(IDD_PROPPAGE_MEDIUM2);
psp[1].pszIcon = NULL;
psp[1].pfnDlgProc = (DLGPROC)Page3DlgProc;
psp[1].pszTitle = TEXT("Schedule");
psp[2].dwSize = sizeof(PROPSHEETPAGE);
psp[2].dwFlags = PSP_USETITLE;
psp[2].hInstance = NULL;
psp[2].pszTemplate = MAKEINTRESOURCE(IDD_PROPPAGE_MEDIUM3);
psp[2].pszIcon = NULL;
psp[2].pfnDlgProc = (DLGPROC)Page4DlgProc;
psp[2].pszTitle = TEXT("Scan Options");
psh.dwSize = sizeof(PROPSHEETHEADER);
psh.dwFlags = PSH_PROPSHEETPAGE |PSH_USECALLBACK | PSH_MODELESS;
psh.hwndParent = NULL;
psh.hInstance = g_hInst;
psh.pszIcon = NULL;
psh.pszCaption = "Automatic Virus Check";
psh.nPages = sizeof(psp) / sizeof(PROPSHEETPAGE);
psh.nStartPage = 0;
psh.ppsp = (LPCPROPSHEETPAGE) &psp;
psh.pfnCallback = (PFNPROPSHEETCALLBACK)PSheetCallback;
return (HWND)PropertySheet(&psh);
}

I set the "Center" Property for pages also. As there is property page dialog box for tabs(Pages)...
There is no dialog for Propertysheet..Creating programmatically..

I said, in the "future". The reason why I asked you to create a new thread is, your query will get more visibility and more people may give you valuable inputs. This thread is kind of buried now and I'll try helping you out, but I may or may not be able to solve it. If I fail to solve your query, then start a new thread.
Now, please show me what you tried with SetWindwoPos().

Please try this code and tell me if it worked:
HWND hPWnd = CreatePropSheet();
RECT rc;
GetWindowRect(hPWnd, &rc);
SetWindowPos(hPWnd, NULL,
((GetSystemMetrics(SM_CXSCREEN) - (rc.right - rc.left)) / 2),
((GetSystemMetrics(SM_CYSCREEN) - (rc.bottom - rc.top)) / 2),
0, 0, SWP_NOSIZE | SWP_NOACTIVATE);

Yeah..Thanks Rajesh
This code works...
Initially i was doing something like that
g_hwndPropSheet = CreatePropSheet();
RECT rect;
GetWindowRect(g_hwndPropSheet, &rect);
int xL = LOWORD(dwSize) / 2 - (rect.right - rect.left) / 2;
int yT = HIWORD(dwSize) / 2 - (rect.bottom - rect.top) / 2;
SetWindowPos(g_hwndPropSheet, NULL, xL, yT, -1, -1,
SWP_NOSIZE | SWP_NOZORDER | SWP_NOACTIVATE);
g_hwndPropSheet is type of HWND.
Thanks again..

Why do you repeatedly say DateTimePicker? It belongs to the .NET framework class library. I believe that we're talking about CDateTimeCtrl.
Ashish Chauhan wrote: GetSystemTime(&st);
What are you doing using GetSystemTime()? This would get the computer's time and not the time that's being shown in your DateTimeControl()! Please use the DateTime_SetSystemtime Macro to set the value into your control. Also, check the return value of this macro. It should return a non zero value if it didn't fail. Try that and let me know the result.

Hi All,
I Create some thread by using the function _beginthreadex.
I hold some handle to this thread
(ThreadHandle = (HANDLE) _beginthreadex(...))
And now i want to kill the running thread and i don't know how to do it.
thanks for any help...

Let the thread procedure function exit by itself.

There's a few ways to do it.
The nice way:
Before starting the thread, create an event object (CreateEvent). Share this event handle with your thread, check it periodically -- and when it becomes signalled, have the thread exit itself. It's always best for the thread to exit gracefully.
HANDLE hEvent = CreateEvent();
_beginThreadEx( NULL, 0, YourThreadFunc, hEvent, 0, &ThreadID );
unsigned int __stdcall YourThreadFunc( LPVOID pData )
{
HANDLE hEvent = (HANDLE)pData;
while ( WaitForSingleObject(hEvent,0) != WAIT_OBJECT_0 )
{
DoSomething();
}
return 0;
}
SetEvent(hEvent);
The nasty way:
TerminateThread( threadHandle );

I cant in my code check for event ... but using TerminateThread look better option for now.
but I dont understand why dont use the TerminateThread ?
I rad about TerminateThread in MSDN - and they wrote "TerminateThread is a dangerous function that should only be used in the most extreme cases" - but i dont see any problem.
Can you explain ?
Thanks.

Because it is not a natural way to exit your thread. First, if you allocated some resources in your thread, there's no way you will be able to clean them if you are using TerminateThread.
Second, you have no control about what you are doing: you will terminate the thread whatever it was processing. It means you can terminate it in the middle of something important that will be left not terminated (e.g. if you communicate with an external device, you started to send some data to it and then brutally stop it, leaving the device in an unknown state).
It is far better to handle that yourself, using a flag for example: you check regularly if this flag is false, if that's the case, you exit nicely the thread function (the general idea is having a loop that checks for this flag).

If this is your first jaunt into threading, you'll run into some problems. There's a whole bunch of things that you need to learn about in order to make threading work right.
But once you figure them out -- you'll LOVE threading!
The most important lesson is "Don't take shortcuts" -- a certain level of discipline is important when constructing a program that employs threads.
I think I've forgotten how to write an unthreaded program. What did we do before threading?

Hi,
Can anybody please explain, How virtual destructor works under the hood?
What happens exactly with virtual table?
Thanks in advance.
|
|
|
|
|
I think:
The destructor goes into the vtable.
When the destructor is called -- the top-most constructor is called first, executed, then in turn, the each of the parent destructors are called. The order is the opposite of the order that the constructors are executed.
If you didn't do a virtual destructor, the parent destructors are hidden. I, personally, always use virtual destructors.
Just off the top of my head.
