Hi Friends,
Has any one of you tried setting the compiler options from command line??
If so, please give me step by step procedure for setting options for my VC++ application.
Thanks in advance.

Hi all
I have seen in MSDN while describing windows function they describe about system queue.
I dont know what events will enter into systems queue. when an entry in the system queue is removed(is it after processing).
how is this system queue different from message queue or is it same
thanks in advance

System Queue is the Queue that maintains all the Services(Processes) that are running on the system.
where as message queue is specific to a particular Application(Active Application)..

Sorry for the previous mail.
System Queue has different meaning to Message Queue.
Here is the explanation from MSDN.
Queues that are generated by Message Queuing are referred to as system queues, internal private queues, and outgoing queues.
System queues include the following types of queues:
Queue journals: Queue journals are queues that contain copies of all messages removed from a queue with target journaling enabled.
Computer journals: Computer journals are queues that contain copies of all messages sent from a computer with a request for positive_source journaling.
Dead-letter queues: Dead-letter queues contain messages that were sent from a computer with a request for negative source journaling and could not be delivered. Message Queuing provides a transactional dead-letter queue and a nontransactional dead-letter queue.
Connector queues: Connector queues are used when sending messages to foreign queues.
The computer journal and the dead-letter queues are listed in MMC snap-ins (or the Control Panel applet) in the System Queues folder.
Applications can read the messages in system queues, but cannot address messages to them.
Thanks for u r post. I learnt a lot because of u r post.

Thank You

I'm using following statement to create a new thread,
AfxBeginThread(SocketConnection,this);
Method to be invoked
UINT SocketConnection(LPVOID pParam)
{
return 0;
}
But i'm getting the following error message; whats wrong with my code how to resolve it
'AfxBeginThread' : none of the 2 overloads can convert parameter 1 from type 'UINT (LPVOID)'

Have you defined the Thread function SocketConnection in the header file of the class.
If yes remove the function declaration in the header file and then try and compile your code.
Somethings seem HARD to do, until we know how to do them.

No it says UnDeclare Identifier
AfxBeginThread(SocketConnection,this);
UINT static SocketConnection(LPVOID pParam)
{
return 0;
}
Error Message
error C2065: 'SocketConnection' : undeclared identifier
|
|

|

Your need to define the function before you call this . SO check it.

if (m_Thread != NULL)<br />
m_Thread->ResumeThread();<br />
}<br />
<br />
<br />
UINT MyThread( LPVOID pv )<br />

<br />
return 0;<br />

Actually Class Function which is going to used as Thread, is decalred as STATIC to save it from Object Boundation!

If Function Declared In Class is going to used at Thread, then it declared Static otherwise not

The definition function for the function SocketConnection should be at the top of the file if it's not declared before the AfxBeginThread statement.
UINT SocketConnection(LPVOID pParam)
{
return 0;
}
void CSomeClass::SomeMethod()
{
AfxBeginThread(SocketConnection,this);
}

You are right Nibu. This is allowed in C++, but not in C.

It's allowed only if you have a declaration before the function is referenced.

Here is my small issue
SocketThread = AfxBeginThread(ReceiveMessage,this);
UINT static ReceiveMessage(LPVOID pParam)
{
return 0;
}
Since i'm not defining this class inside the Header file i'm not able to access any controls and its values. Previously i had as like below
strSocketData.SetWindowText (strResult);
//strSocketData is a control variable.
How can i access it in my "ReceiveMessage" method.

Yes it sounds Good... i can able to read and write data.
Shall use this?. Is it it advisable?. Make sure i'm using it in MFC Activex control. You mentioned that it is not safe is there anyother alternate.
CYourDlg* pYourDlg = reinterpret_cast< CYourDlg* >( pParam ); pYourDlg->strSocketData.SetWindowText( pYourDlg->strResult );

Well did it work? 
sivaprakashshanmugam wrote: You mentioned that it is not safe is there anyother alternate.
No it's not at all thread safe to pass around MFC objects. Instead pass the HWND of your dialog. Then use SetDlgItemText to set the text for the item.
SetDlgItemText( hDialog, IDD_DIALOGCONTROL_ID, _T( "This is thread safe" )); Well you cannot retrieve the strResult parameter too. To get around this store the buffer of strResult inside another pointer. Put both the handle to the dialog and the pointer to the buffer inside the struct and then pass this struct object to the thread.
