I would begin from the other side:

0. remove your VectorArray using

1. Inserting loop at initializing:

NOTINFO* pInfo = new NOTINFO;
pInfo->nEpoch = ...;
// filling of pInfo->szDateTime and pInfo->szEvent
// setting pInfo as item param (not &pInfo)

2. URGENTLY: Removing loop at destroying:

NOTINFO* pInfo = (NOTINFO*) GetItemParam(i);
delete pInfo;

virtual void BeHappy() = 0;

Re: Listview Sorting

arun_pk21-Apr-10 22:45

arun_pk

21-Apr-10 22:45

NOTINFO* pInfo = new NOTINFO;

this has to be done inside or out side the loop

Inside the loop, for each item (as well delete in the destroying loop) Smile | :)

what i did is
inside for loop

...........
NOTATIONINFO *NotationList = new NOTATIONINFO;
.......
.......
lvi.Param =(LPARAM)NotationList; 
.......

new for loop

for (int i = 0; i < Nnots; i++)
		{
			NOTATIONINFO         *NotationList      = (NOTATIONINFO*)GetItemParam(i);
			delete NotationList;
		}

error ...... Frown | :(

Please place the second loop
at destroying of the list (WM_DESTROY reaction)

...
case WM_DESTROY:
{
  LVITEM lvItem = {0};
  for (int i = 0; i < Nnots; i++) {
    lvItem.iItem = i;
    lvItem.mask  = LVIF_PARAM;
    ListView_GetItem(hwndList, &lvItem);
    NOTINFO* pInfo = (NOTINFO*) lvItem.lParam;
    delete pInfo;
  }
}
break;
...

Allow/Disallow a user from changing system time

Aseem Sharma31-Mar-10 17:17

Hi all,

I am working on a feature where in we can allow/disallow changing system time to any user. We can run this application from an administrator's account and set if a particular user can change system time or not. Even the administrator (who itself is logged on) itself can allow/disallow himself changing time.

While googling I found that there is some, The system user right SeSystemtimePrivilege that controls the ability to set the system time. I could not find how to complete my feature via the privilege SeSystemtimePrivilege using C#.

Can somebody help me how to that using c# (or even C++). Even if there is some other way of implementing this feature, please let me know.

Thanks in Advance
Best Regards
Aseem

Can you check if the Test.bsc file exists on the specified location? Following MSDN link mentions reasons for this error: http://msdn.microsoft.com/en-us/library/aa261920(VS.60).aspx[^]

Do you compile for WinCE ? Smile | :)

1) You shold not mix CE and PC projects in a solution

2) Please check the projects target configuration
in the solutions configurations manager.
2a) CE_MUST: CE target SDK is installed and the project has its configuration
2b) Sometime a CE/PC project has not a - for example Debug - configuration

3) Try to delete *.bsc files from your solution directory and rebuild all

Multithreading using AfxBeginThread

I am creating thread using AfxBeginThread in Visual Studio 2005 and the first parameter of this function is function pointer so i am passing member function pointer of that class but it gives error i.e.

my code is:

AfxBeginThread( &CMultithreadingInDialogDlg::MyThreadProc, GetSafeHwnd() );

in which MyThreadProc is member function. and the error is

error C2665: 'AfxBeginThread' : none of the 2 overloads could convert all the argument types.

but it is working if i am passing function pointer of any static function or global function

thanks in advance.

Is MyThreadProc() a static member of CMultithreadingInDialogDlg?

MyThreadProc is not a static function, it is simple member function.

Re: Multithreading using AfxBeginThread

Which means it cannot be used an argument to AfxBeginThread().

That is also the "classical" way
to pass - for example - a private static function of a dialog... Smile | :)
