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

I realize that this may not be the ideal message board for this question, but it seemed like the best place, so here it is.
What would be the best way to monitor/log memory & cpu usage for a specific process in the general windows environment? -Thanks

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).

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...

Probably you will must determinate

and then include its usage... Smile | :)

No, include the lib of the unresolved symbol to the linking process.
It could be perform in a .cpp file as following too Smile | :)
