No, I really like such mechanism (on the other hand, there are certain framworks built on the top of it...).

I guess with the Window's version, I always disliked the lack of type safety and the way it was laid out. I will concede that it is quite a legacy interface in this day and age. Not that anything Microsoft has come up with since then is a lot better. Sniff | :^)

Yes, but even in C, I like my code pretty. Poke tongue | ;-P

I'd have declared a structure for each message type and just passed a pointer as part of the message. Or even the first field of the structure could have been the message type. Still not C++ type safe but I think more elegant. It would have made interpreting the message a bit easier than remembering which bit went it which parameter and still have pointers to structures occasionally flying by. But then I'm not a computer scientist. Cool | :cool:

Wow, tons of structs.

Pointers don't always make sense in Windows messages (pointers are process-scope valid).
Moreover, I think it is dangerous to use pointers in every Windows message, if you don't need a pointer, don't use it (don't get me wrong, pointers are useful, but, each time I see a pointer I ask to myself: is it valid? Should I free the memory?).

I don't worry about messages sent by Windows: any application may post and send messages like the operating system does.

using WMI classes are good for this purpose eg:- http://msdn.microsoft.com/en-us/library/aa390423(VS.85).aspx

But if you like to use API then you have a lot of options:--
One such is PSAPI
Just refer :- http://msdn.microsoft.com/en-us/library/ms681920(VS.85).aspx.

WMI is having high performance, and it has a good extensible event mechanism.
But PSAPI is not a bad option , but it wont support Windows 9X Smile | :)

Is this a coding question, or just a general Windows question? If the latter, use the Performance Monitor (perfmon.msc).

Taskbar is hooked

I have hooked taskbar. Below code is the new window procedure for task bar.
But when I tried to send message with valid m_hDlgWnd of my application window. But it is not working. Confused | :confused:

Is it not possible to send message from this task bar window procedure?

LRESULT CALLBACK NewProc(
  HWND hwnd,      // handle to window
  UINT uMsg,      // message identifier
  WPARAM wParam,  // first message parameter
  LPARAM lParam   // second message parameter
)
{
	switch (uMsg) 
	{
          case WM_PAINT: 
            ::SendMessage( m_hDlgWnd, WM_TASKBAR_UPDATED_EVENT,0,0 );// NOT WORKING
            ::SetEvent( m_hTaskBarUpdatedEvent ); // NOT WORKING
            ::MessageBeep( MB_OK );
             break;
	}
	
	return CallWindowProc( OldProc,hwnd,uMsg,wParam,lParam );
}

After finding the window again, it is worked. Smile | :)

case WM_PAINT: 
            {
                m_hDlgWnd = ::FindWindow( NULL, "HackTaskBar" );
                ::SendMessage( m_hDlgWnd, WM_TASKBAR_UPDATED_EVENT,0,0 );// WORKING
                ::MessageBeep( MB_OK );
                 break;

Just be carefull with SendMessage, you can run into deadlocks (i'm not saying you will), if the timing isn't that important for what you need, i recommend using PostMessage instead...

[edit] I mean if you use SendMessage between different threads/processes...
