Hi Alok
See.. If I am setting the priority of the application process as a REALTIME_PRIORITY_CLASS in its OnInitDialog() function (if not in this function, where?) and setting the thread created by that application using SetThreadPriority() (calling in the thread itself) to TIME_CRITICAL_PRIORITY level , what would be the priority of the thread that I have created? Can any process or thread interrupt the thread I have created?

According to MSDN, REALTIME_PRIORITY_CLASS :-" A thread with a base priority level above 11 interferes with the normal operation of the operating system. Using REALTIME_PRIORITY_CLASS may cause disk caches to not flush, hang the mouse, and so on.
"
So i believe no process or thread wil interrupt your high priority thread

I think I'll never buy products from your company  .
Seriously, I don't think this is a good solution ! Maybe the user doesn't want that your program kills its own applications don't you think ?
A better way would be to solve the problem itself. Maybe this is due to thread priority or something like that.

Hi Cedric
What you said was perfect. But I am using a thread with a real time priority for that. But still the disturbances happen.

Hi:
I overload the CToolBar class , and process the default TBN_GETINFOTIP event to dynamicly changge the tips.
( ON_NOTIFY_REFLECT( TBN_GETINFOTIP, OnGetInfoTip)
the way works well. Then I create a toolbar in the statusbar in one of my project, but this way doesn't work at all. I couldn't get the OnGetInfoTip event form the toolbar created in the statusbar now. Why? how could I do?
Thanks

Get the tooltip control associated to your toolbar (MFC : GetToolTips()) and call the RelayEvent() function once after the init of the toolbar.

Hey guys,
I'm absolutely not a experienced programmer but i have a problem, i will be happy someone can help me.
I have a dialog class CSimulator with a number of timers:
//part of the XXXXX.h file ****************************************************
class CSimulator : public CDialog
{
DECLARE_DYNAMIC(CSimulator)
protected:
virtual void DoDataExchange(CDataExchange* pDX); // DDX/DDV support
DECLARE_MESSAGE_MAP()
...
...
...
public:
virtual BOOL OnInitDialog();
void OnTimer(UINT nIDEvent);
//part of the XXXX.cpp file ****************************************************
IMPLEMENT_DYNAMIC(CSimulator , CDialog)
void CSimulator::DoDataExchange(CDataExchange* pDX)
{
CDialog::DoDataExchange(pDX);
}
BEGIN_MESSAGE_MAP(CSimulator, CDialog)
ON_WM_TIMER()
...
...
END_MESSAGE_MAP()
void CSimulator::OnTimer(UINT nIDEvent)
{
...
...
...
CDialog::OnTimer(nIDEvent);
}
When i start the class CSimulator from another class (CWnd) with DoModal() everything is working fine and the function CSimulator::OnTimer(UINT nIDEvent) is called after setting a timer with SetTimer(IDTIMER,50,0);
But  when i start the class CSimulator from another class (CWnd) with m_Simulator.Create(IDD_SIMULATION_DIALOG); (m_Simulator is the instance of class CSimulator)
i have a problem. In this situation i don't receive the ON_WM_TIMER message  .
Note: At another situation i need the class CSimulator (CDialog) showed in a window, but in this situation i only need the algorithm of the class, only modeless
What i'm doing wrong? I search a lot, but don't see the problem, can anyone help me?
 Thanks, Bart

ON_WM_TIMER requires a message pump to be running, that's why you are not getting the messages.

Thanks, but how can i solve the problem? What is it for a message pump?

Probably a silly question but where are you calling SetTimer() from?
If you are calling it in IntiDialog() in the CSimulator class then
it is never getting called when you instantiate and create the dialog
class from your CWnd class. If not then maybe you have some other code
in InitDialog() that needs to be run.

Hi,
I've trying to create a browser helper object (BHO) for explorer. I've got a main "manager" class that initializes two objects. Each of these uses an simple XML parser (using MSXML). Now, when parsing XML files, I want to store the results to a struct array (not a class). The struct array is in turn comprised of a few other struct arrays. All mem allocation is static, only the topmost parent struct array is dynamically allocated. That's where the problem is: When I allocate (using new) the struct arr in the first object, its ok. Then when I init the second obj, the new fails and crushes the explorer. I did a simple test in the second obj:
int *i = new int[x];
when x is <255 it's ok. if x>=255 then it crashes (and of course, my struct arr is bigger than 255*sizeof(int) bytes). I don't think I have any serious mem leaks in the code before this.
Has anyone seen this before? Is there a memory limit imposed by explorer (unlikely as it sounds)? I would appreciate any comments.
Thanks,
Pete

It indicates that the implementation of the
int __cdecl sumArray(int * const,int)
function is missing.

You seem to have declared the function sumarray(...) but forgot to implement it.

Hello,
I copied a large file from one disk(source) to another disk(destination). After this I made (manually or programmatically) some changes in the file on the source disk. Now, these changes should reflect in the file on the destination disk also. In order to achieve this, I copied the file again from source to destination. Since the file is a large one this method is not efficient. Because, for any minute change, I have to copy the entire thing.
Is there any way to copy only the updated portion from the file on the source disk to the file on the destination disk?
Hoping to get a reply soon.
Thanks in advance.
regards,
Jahfer V P.

When you are making changes to the file, make another file (changes-file) also, with your own file format:
Repeat (1) below for every change:
1- The size of data in four bytes (long int) then four bytes (long int) for offset into the file for the data, then the data. Write this into your "changes-file".
Then when you need to update the destination file, repeat (2) below until the end of the file.
2- Read the "changes-file", and correctly read the length of data, offset of data, and the data. Then open the destination file in update mode, move into it at the correct offset, and write out the data you read from the "changes-file".
Does that solve the problem?
this is this.

Dear khan++,
That doesn't solve my problem, because I am not the person going to update the file. More over, the file may get updated not only at its end but anywhere in it.
Any other idea?

Jahfer V P.

I don't get it.
The technique I gave can update the file anywhere in it, not just the end, that is why I asked for an offset field.
I hope someone else can help as I am about to logout for the day.
this is this.
