Just use the thread handle and thread id from either:
GetThreadId(thread_hnd)
GetCurrentThreadId()
From MSDN:
Until a thread terminates, its thread identifier uniquely identifies it on the system.
This means you must also track when a thread you are interested in dies.
For threads you start you can just catch DLL_THREAD_DETACH.
For others (e.g. started by MS CRT or nVidia OpenGL driver) you won't always get a DLL_THREAD_DETACH.

I have a dialog based app. In the OnInitDialog() function I am showing for some time a dialog box without any buttons and system menu. It shows a waiting message. It appears into the upper left corner of the screen. How can I make it apper centred to the screen?

Hi all,
i want to use a bitmp variable as a global var,
so i wrote this code
<br />
CNeLoPApp theApp;<br />
CBitmap bitmap;<br />
bitmap.LoadBitmap(IDB_BITMAP1);<br />
HBITMAP hBitmap = (HBITMAP) bitmap.GetSafeHandle();<br />
But i had those errors
error C2143: syntax error : missing ';' before '.'
error C2501: 'bitmap' : missing storage-class or type specifiers
error C2371: 'bitmap' : redefinition; different basic types 
error C2143: syntax error : missing ';' before '.'
Whayt's wrong with that code.
PS: i wrote nthq into the stdafx.h
"The Ultimate Limit Is Only Your Imagination."

Where are you calling these methods from?

I changed some lignes:
in the stdafx.h
<br />
extern CBitmap bitmap;<br />
extern HBITMAP hBitmap ;<br />
In myprog.cpp (where 'TheApp' var is declared by default )
<br />
bitmap.LoadBitmap(IDB_BITMAP1);<br />
hBitmap = (HBITMAP) bitmap.GetSafeHandle();<br />
but now on aform when i try to set the bitmap to a button via OnInitialUpdate()
<br />
m_Next.SetBitmap(hBitmap);<br />
I have this error
: error C2065: 'hBitmap' : undeclared identifier (that hBitmap is not declared on that form) 
"The Ultimate Limit Is Only Your Imagination."

Ok i foud the solution.
all that i do is to delete the debug folder and rebuild the prog. and it works. 
But I still have some issue:
when i run the prog the button dosn't display the bitmap. but when i move the window or clik on it the bitmap appears. I even put the m_Next.SetBitmap(hBitmap); into the OninitialUpdate() and OnPaint().
how ciould i resolve that little prob

There's no reason to extract the HBITMAP from a CBitmap into a separate variable.
The handle is available from the CBitmap object any time.
That aside, you need to separate the global variable definitions from the code that
initializes them. For example:
CNeLoPApp theApp;<br />
CBitmap bitmap;<br />
HBITMAP hBitmap = NULL;<br />
<br />
BOOL CNeLoPApp
::InitInstance()<br />
{<br />
bitmap.LoadBitmap(IDB_BITMAP1);<br />
hBitmap = (HBITMAP) bitmap.GetSafeHandle();

I had to declare The bitmap and hBitmap as global var coz i had to Forms A & B and in both of them i hve a buttom that uses the same bitmap but when i goback from B to A the prog crashes (Erreur and stops).
So with global vars i had no more the erreur. but when i lunch tha prog, i have to wait 3 or 4 seconds to viex the button with the bitmap (may be it's a time prob for loading the bitmap).

First, CBitmap is a C++ wrapper for an HBITMAP handle. To have a separate HBITMAP variable
is redundant and instantly doubles your maintenance for a single object. There's NO valid reason
for doing that. You can use your CBitmap object anywhere a HBITMAP is needed, without even having
to cast it, because CBitmap has a HBITMAP cast operator.
Second, why not take advantage of the object-orientedness of MFC and encapsulate the
bitmap object in the class that uses it? What makes you think two buttons can safely share the
same bitmap?
There's rarely a need for global variables in MFC. If you think you need a global variable, there's
probably a better way to design your code.

I have 2 forms on each of which i load the same bitmap for a button (let's say a button labeled Next).
when i load the bitmap and the Hbitmap on form A all go well
when i load the form B after a click on button from form A all go well
when i wanna goback to form A aftr a clik on a button on Form B the prog Crach down. That's why i used the bitmap and the hBitmap as global var?

How do you know the crash is related to the bitmap?
If it is taking 3-4 seconds to load a bitmap, it's either really big, or
there's a problem somewhere else.

You can also use of HBITMAP without CBitmap.

Hi all,
I intend to filter IPv6 packets.
I have already succeeded in capturing and decoding the packets n a human readable format.
Now i want to block some unwanted IPv6 traffic
say:
I do Win XP to drop packets with destination address A and port A1 and source address B and port B1
how can I do this?
will manipulating the IPv6 routing tables on my machine work?
I did
C:> netsh
netsh> interface ipv6
interface ipv6> show routes
this showed me some routes for IPv6 traffic going out of my machine,can i manipulate them to block certain traffic.
Is there any other way of doing it, are there some libraries,classes, methods that can help filtering IPv6 packets.
please help
thanks and regards

I've managed to compile and run all the samples in the book so far, but all the sudden this code comes up and gives me nasty headaches.
When i'm trying to compile the code below everything goes fine until the compiler tries to link it.
Here's the error i get:
cd /Users/summer/Documents/C++/xcodeproject/ex<br />

And here's the code:
#include <iostream>
using namespace std;
class Form
{
public:
Form() {}
virtual ~Form() {}
virtual long HentAreal() { return -1; }
virtual long HentOmkreds() { return -1; }
virtual void Tegn() {}
};
class Rektangel : public Form
{
public:
Rektangel(int laengde, int bredde):
densLaengde(laengde), densBredde(bredde) {}
virtual ~Rektangel() {}
virtual long HentAreal() { return densLaengde * densBredde; }
virtual long HentOmkreds() { return 2*densLaengde + 2*densBredde; }
virtual int HentLaengde() { return densLaengde; }
virtual int HentBredde() { return densBredde; }
virtual void Tegn();
private:
int densBredde;
int densLaengde;
};
void Rektangel::Tegn()
{
for (int i = 0;i < densLaengde;i++)
{
for (int j = 0;j < densBredde;j++)
cout << "x";
cout << "\n";
}
}
class Kvadrat : public Rektangel
{
public:
Kvadrat(int laengde);
Kvadrat(int laengde, int bredde);
~Kvadrat();
long HentOmkreds() { return 4 * HentLaengde(); }
};
Kvadrat::Kvadrat(int laengde):
Rektangel(laengde, laengde)
{}
int main()
{
cout << "Do stuff";
return 0;
}</iostream>
When i remove
Kvadrat::Kvadrat(int laengde):<br />
Rektangel(laengde, laengde)<br />
{}
It compiles without problems. But i want to create a rectangel upon creation of a square! (rektangel == rectangel && kvadrat == square in danish)

You need a body for Kvadrat's destructor.

wow.. that was too simple. i feel stupid.

you forgot:
