What version of compiler are you using?
Why is common sense not common?
Never argue with an idiot. They will drag you down to their level where they are an expert.

I am unable to understand the difference in both the pointers, managed one with __gc and unmanaged pointer, please refer to the program and let me know the differences between them, and what is the advantage of _gc * coming for one time or coming for two times an how much difference it can make to the garbage collection or how much advantageous is it?
__gc struct G
{
int i;
};
__value struct V
{
int i;
};
int main()
{
// defaults to V __gc * __nogc * ppV;
V ** ppV;
// defaults to V __gc * __nogc * __nogc * pppV;
V *** pppV;
// defaults to G __gc * __gc * ppG;
G ** ppG;
// defaults to G __gc * __gc * __nogc * pppG;
G *** pppG;
// defaults to G __gc * __gc * __nogc * __nogc * ppppG;
G **** ppppG;
}
Thanks,
Syed

hi i am newbie...
i am a bit confused in socket programming.
my question is..
how can we communicate thru sockets between two different Ips as these two ip are have their internal IP and external IPs.
suppose that communication shud be between A and B.and A and B are having their internal and external IPs.
1. how the server(A) shud listen (ok it will listen to port x)?.if the client(B) connect to external IP of A..will that each to the server A?
2.if server (A) sends a message to Client (B) on B`s external IP will that reach the client B?
any one please pull me out of this confusion . plz point out if i am wrong or suggetst me how can i wright socket application ( chat for examaple) between these two IPs those of each are having two IP`( internal and external).
--Thanks in advance.

A Socket needs an IPAddress to communicate with its another peer.
1. It doesnt care whether it is External (PublicIP) or Internal (LAN)(hope my
interpretation of internal and external is right) it is handled by the DNSserver (publicIP) or your LAN GateWay.
2. Once the Connect--listen-- accept sequence is over, you can exchange messages between any two connected sockets.

Let's start inside the LAN, here your two peers communicate using the internal LAN IP addresses.
It gets a little bit more difficult when you communicate outside the LAN and the internet IP address (external IP address) is different to the LAN IP address (internal IP address). Generally two peers on the internet have to communicate via their external IP adresses, typically the router or the proxy does a kind of network-address-translation for you. For example if your internal IP address is 192.168.1.1 it could from the outside look like as you would have an external IP address 87.164.52.42. This network-address-translation often works automaticaly for the outgoing traffic (depends on your network setup), but it usually does not work automatically for incoming traffic (internet to LAN).... aka "firewalled computer".
Hope this helps for a start.

Once all thread started from the main thread. I have put the follwing wait message
in main thread to handle the child thread.Means until completed all the child threds Main thread must be wait.
for that I had put.
WaitForMultipleObjects(2, hThread, FALSE, INFINITE);
will it stop the messagepumping ?
because when thread reach at the following line .
<br />
SendMessage(hwndCmbProfile,CB_GETCURSEL,0,0);<br />
The application does stop the working .In Task manger it shown application not responding.
Is WaitForMultipleObjects affect on os message pumping??????
why the application get hang??

If you don't start any new thread, your application has only one thread. It means that if you do something that takes a lot of time, your application will not respond during this time, because the message loop is in the same thread. Thus, if you wait for something in the main thread, your application won't respond (unable to process messages) until the wait is terminated and until you are able to process messages once again.

Firstly this line looks funny:
WaitForMultipleObjects(2, hThread, FALSE, INFINITE);
If hThread is thread HANDLE, as the Hungarian prefix suggests, then this should not compile. It looks like you're just waiting on one HANDLE. I'd guess hThread is a pointer to an array of HANDLEs: if this is the case the "h" prefix is confusing and will throw programmers that are aware of Hungarian prefixes.
Secondly, no message pump is running so the SendMessage in the worker thread will (and should) block. What you need is the MsgWaitForMultipleObjects function. Look in the ATL source code in the function AtlWaitWithMessageLoop for an example of its usage.

Messages sent to a window must be processed by the thread that created the window. When a worker thread calls SendMessage(), it blocks until the message handler returns. Since the message is going to a window (assuming it was created by the main thread, which is uaually the case), the thread that has to handle the message is blocked and can't run, so you've created a deadlock.
You also have a bug in the call to WaitForMultipleObjects() - you say you're passing 2 handles, but only providing one.

Thank you sir,
How can I stop the deadlock situation? and child therad SendMessage to the window.

You should avoid the use of SendMessage() between threads; if the receiving thread is not processing messages your application will deadlock.
Use PostMessage() instead.

Grate !
Thanks! But my Thread application passes through some function where I every next step ,I have used the GUI messaging so now how can i handle that situation.
means fetching the values from the different control like combobox ,static text, listview during the thread is runing.
But thank you very much,
I will try it for PostMessage.

As Stephen suggested above, AtlWaitWithMessageLoop() is one way to have a thread wait and still be able to process messages. It's the method I use.

sir,
I have found the help for that and I am satisfy with this answer but could you guide me where should i write this function?
I mean in my Mainthread or the successive function call from the Mainthread.( )
suppose ,
e.g.
<br />
for(....)<br />
{<br />
hThread[i]=(HANDLE ) _beginthreadex(NULL, 0, &Thread, l, 0, &tid);<br />
}
here  ????? where should I call and where should I defined ?
<br />
unsigned __stdcall Thread(void* pArguments )<br />
{ <br />
HRESULT hr=NULL;<br />
struct argument_list *Lparam= (argument_list *)pArguments ;<br />
Package pkg;<br />
static int threadID;<br />
threadID++; <br />
{<br />
hr=pkg.EncodeMediaContent(Lparam->pszInFile,Lparam->pszOutFil,Lparam->hwndParent,Lparam->Host,Lparam->UserID,Lparam->InitPackageRequest,Lparam->ScriptFile,Lparam->Port,Lparam->hList,Lparam->_ProtectSet,Lparam->hWndinoutfiledir,Lparam->hwndEncrypt);<br />
}<br />
if(hr==S_OK)<br />
{ <br />
MessageBox(0,L"thread gone finished" ,L"therad",0);<br />
_endthreadex( 0 ); <br />
}<br />
<br />
<br />
threadID--; <br />
return 0;<br />
}

Hi,
I am looking for windows api for finding out that
Whether a system is connected to Primary domain controller or its a local workstation?
If i am logged on to a domain controller i would like to know the domain name?
And if i am on a local machine then i would like to know about the computer name?
I tried GetComputerName but it doesn't give the domain controller Domain name in case of domain.
I want to somehow know if its on a domain or not??

is it right to say that preprocessor directives is
#include<iostream.h>
and
preprocessor is a character
#

The preprocessor is a program that takes a source file and does things to it before the compiler sees the file. Directives are instructions to the preprocessor telling it what to do. More info here: clickety[^]
