Thanks & Regards,

what's the gold bar in IE ???

Gold Bar also comes in firefox browser. Whenever we are browsing a web site for some web sites one 'Activex control' pops up just below the Frame window but above the client area. Color of that Bar is Yellow. That is known as gold bar. For your experiment you can create a simple xml file and open it in your IE. I hope you will get gold bar.

The following lines of code generate a unhandled exception in reading memory location error in my MFC program
Can anyone please tell the reason 
//The CUIThread class
class CUIThread : public CWinThread
{
DECLARE_DYNCREATE(CUIThread)
public:
virtual BOOL InitInstance();
};
IMPLEMENT_DYNCREATE(CUIThread,CWinThread)
BOOL CUIThread::InitInstance()
{
m_pMainWnd=new CMainWindow;
m_pMainWnd->ShowWindow(SW_SHOW);
m_pMainWnd->UpdateWindow();
return TRUE;
}
//The CMainWindow class
class CMainWindow : public CFrameWnd
{
public:
CMainWindow();
protected:
afx_msg void OnLButtonDown(UINT,CPoint);
DECLARE_MESSAGE_MAP()
};
BEGIN_MESSAGE_MAP(CMainWindow,CFrameWnd)
ON_WM_LBUTTONDOWN()
END_MESSAGE_MAP()
CMainWindow::CMainWindow()
{
Create(NULL,_T("UI Thread Window"));
}
void CMainWindow::OnLButtonDown(UINT nFlags,CPoint point)
{
PostMessage(WM_CLOSE,0,0);
}
CWinThread *pThread=AfxBeginThread(RUNTIME_CLASS(CUIThread));

All of them?? 
How odd.
Have a look at your call stack when your application generates the exception and provide information about which line is generating the exception.
You'll probably find the last reference to your code a few frames down.
Before you provide that info it's not worth digging in to.
And please put your code inside <pre></pre> tags for proper formatting.

Just a stab...

m_pMainWnd->ShowWindow(SW_SHOW); <<---does the window exist yet?
m_pMainWnd->UpdateWindow();
maybe put these in an OnCreate handler?

No no no - that won't work. The window needs to be created on the
new UI thread
(at least that's what it appears the OP is doing)

Ahh, thanks

The error is during Run time
The pointer to the thread "pThread" suddenly changes value to zero on going through InitInstance() function.
Even if i don't create a window derived from CFrameWnd it is generating the error.
The Window derived from CFrameWnd is created but the error is also generated at run time.
|
|
|
|
|
The exception occurs at
if(!pThread->InitInstance){.............} of predefined winmain.cpp
Error occurs in that if statement
The pThread value changes to zero for some reason.

Your code as shown works fine for me.
Where are you calling AfxBeginThread() from?

Sorry for the late reply.Iam calling AfxBeginThread globally.that is iam not calling inside any function or class Iam calling where they usually create the objects of the class
|
|
|
|
|
How? Can you show how you do that?
If you put a breakpoint on the call, is it getting hit?
You may get better results if you call it from the InitInstance() override
of your CWinApp class - before that, MFC may not be initialized yet.

Iam not using CWinApp class
Iam using only CWinThread class
I have to instantiate the application using AfxBeginThread
So InitInstance() won't be called unless I call AfxBeginThread globally.
InitInstance gets called only when a object is created
|

An MFC app has to have ONE CWinApp object.
That's by design. Why are you trying to do it differently?
You need a thread running to create another thread

questions and statements for (your) confirmation:
* more than one device can be associated to an IOCP
* each device would have its own thread pool
* each thread pool is associated to a particular function. which is why ANY of the threads (although usually the last in) in the pool can be awakened each time there is a new entry in the completion queue.
* somehow IOCP knows which thread in a pool to wake up depending on which IOCP-associated device has a completed IO request.
thanks in advance.

True (more than one handle - not necessarily device).
swjam wrote: each device would have its own thread pool
False. The number of threads in the pool is determined by how many threads
are waiting on the completion port with GetQueuedCompletionStatus().

False.

False. You can make no assumptions on which thread waiting in GetQueuedCompletionStatus()
will "wake up", unless you only have one thread in the pool.

i'm still tad confused
say multiple devices are associated to a completion port. surely each function will be different for each thread associated with a device? how then does the system know which one to wake up when an entry appears in the competion queue?

IOCPs are a bit confusing at first
swjam wrote: surely each function will be different for each thread associated with a device?
Not so. There's no parameter passed to GetQueuedCompletionStatus() that associates
the thread with a certain device. You'll need to provide any association yourself
in your overlapped structures.
swjam wrote: how then does the system know which one to wake up when an entry appears in the competion queue?
It's undocumented, but it may just take the next thread waiting in
GetQueuedCompletionStatus(). There's no particular order or association with
a certain thread.
These articles helped me a lot when I first used an IOCP.
They are socket-related but the same principles apply to any
overlapped IO device...

Hi,
I just downloaded WinObj doesn't seem like there is much documentation
Anyway here is my Question
If while stepping thru my Code (Debugging) after I execute CreateEvent (with name) I get a Handle Back
If I then Bring up WinObj Shouldn't I see that Event if I open up the Kernel Object folder
