you can look here also:
UINT ThreadNotifyFunc (LPVOID pParam)
{
HWND hwnd = (HWND) pParam; // Window to notify
HANDLE hChange = ::FindFirstChangeNotification (_T ("C:\\"),
TRUE, FILE_NOTIFY_CHANGE_FILE_NAME ¦ FILE_NOTIFY_CHANGE_DIR_NAME);
if (hChange == INVALID_HANDLE_VALUE) {
TRACE (_T ("Error: FindFirstChangeNotification failed\n"));
return (UINT) -1;
}
while (...) {
::WaitForSingleObject (hChange, INFINITE);
::PostMessage (hwnd, WM_USER_CHANGE_NOTIFY, 0, 2);
::FindNextChangeNotification (hChange); // Reset
}
::FindCloseChangeNotification (hChange);
return 0;
}

class a{
public:

CRecordset rs;//line a
CDatabase db; //line b
};
// my question is shld line b comes before line a

heu, you are trying to create an object, but you assign a member with another member of the same object, which wasn't set yet. so change your code...
i'd like to add a remark. your code is note very beautiful, and worse, it is not very useful.
put your data members in private statement, write your class definition in a .h file, and write the class implementation into a .cpp file :
A.h
<font style="color:blue;">class</font> CA {
CRecordset rs;
CDatabase db;
<font style="color:blue;">public:</font>
CA (<font style="color:blue;">void</font>);
<font style="color:green;">
}
A.cpp
CA::CA(<font style="color:blue;">void</font>) : rs(), db() {
}
<font style="color:green;">

i feel that was the most simple way to express his doubt.
It'd be funny to have .cpp and .h files along for such a simple question.

Members of class are constructed in order, in which are declared. It doesn't depend on, whether they are initialized in class constructor. And it also doesn't depend on the order of member initializers in class constructor.
So in your example the line b should be before the line a.

Hi,
I created a thread using the AfxBeginthread function.
How do I stop this thread from another thread. MSDN resources say that its dangerous to use call TerminateThread. I tried using it too, but it failed to terminate it.
Thanks,
Deepak Samuel.

one way is to set a global boolean flag like g_fExit = true, from whichever thread you want ..so that the corresponding thread sees that and return.

in case you wanna use that call InterlockedIncrement or use a Critical section object in order to prevents more than one thread from using the same variable simultaneously.

Check the CEvent for MFC or the events in general for WIN32
The main idea:
in the loop of the thread that you want to stop, call WaitForSingleObject with WAIT_OBJECT_0 on the event handle, and in case it is signaled you just have to return  and in the other thread just signal the event

i told that was one way and perhaps the simplest.

Both are easy and simple to use, but i would rather go with events as it sure that it would be thread safe.

sounds nice..
please explain the need for thread saftey for this line:
g_fExit = true
 that also with the help of an MFC object !

No, i am not tring to be within the context on this problem only... In general senario where threads need to be syncronised i would use kernel objects rather than some variables.;)

it 'd 'nt be fair if i dont mention the risk of deadlock. For any big and complex program it 'd be programmers nightmare to maintain all those handles.
if he has lot of threads and want to stop them form others. seems you didnt faced any such problem yet.

thats what kernel object are for, using it efficiently gives good results.

i would be greatful if you explain the pitfall in following line if executed from multiple thread.
g_fExitThread=true;
or atleast the need from the kernal resource, to do the above.

PostThreadMessage(ThreadId, WM_QUIT, 0, 0);

The problem with using PostThreadMessage or SendNotifyMessage is that worker threads typically don't have message loops, so these functions are not helpful always.
