Create a named event using CreateEvent[^].
Create a thread in your service using CreateThread[^].
In the thread wait for the event to be signaled using WaitForSingleObject[^].
If you want multiple notifications, for example, one for window creation, another for window activation etc., create one event for each and use the WaitForMultipleObjects[^] in your service thread.

I am not sure about the best practice, how ever I guess message sending to the main window would be a bad mechanism, cause in windows vista, you cannot sent message from a process of low Integrity to high Integrity. check here [^]for details

Maybe, there is another way to do what I want, without using hooks. I use shell hook to detect that user change activated window to other application. It is not good for me that every process must load my hook dll and fire that hook. But at this time I dont have better idea.
Any tips?

i want to know how to send the input that i was write in rich edit to device??
the idea is simple...when i push the S key...the device also received s...

I recommend giving more details about your project, what kind of device, how is it connected to the computer, what protocol is it suposed to be using, otherwise don't expect any usefull answers. Good luck.

From your description it would seem that you need to capture key presses, so your program would need to respond to the WM_KEY type messages and then send each character to your device. However you do not specify what type of device you are interested in so it is impossible to know how to send it the character.
I do not understand what this has to do with rich edit!

<br />
IXMLDOMDocument *pDoc = NULL;<br />
BSTR bstr = NULL;<br />
...<br />
bstr = filename.AllocSysString();<br />
hr = pDoc->load (bstr, b_load);<br />
filename is a CString type,how can i slove this problem?
i 've tried ,then i have no regret

The load's prototype is below, this is the reason.
virtual HRESULT STDMETHODCALLTYPE load(
VARIANT xmlSource,
VARIANT_BOOL *isSuccessful) = 0;
One solution is this.
#include <comdef.h>
...
bstr = filename.AllocSysString();
_variant_t file(bstr);
hr = pDoc->load (file, b_load);
|

|

Or you can use the ATL class CComVariant in a similar way.
CComVariant file(filename);
CComVariant success(false);
hr = pDoc->load(file, &success);

To clarify, you want AppB to monitor AppA's messages?

You know that you could also use Spy++[^]. Shows you window messages and even more.

Why do you need to do such a thing? What exactly are you writing? Can't you just have App A to send only relevant messages to App B instead?

My Basic requirement is to monitor system standbay/shutdown message from window .But i need to do that in AppB (which is a non window based application). But application AppA is window based so i am receiving all these StandBy/shutdown messages.
So if there is a way to check when system goes shutdown from non-window based appliacations , than my need will be satisfied.

why don't you add a window to your non-window app, so you can get window messages?
you could make it invisible, or locate it outside the desktop area.

1. open the dialog in the resource editor.
2. open the 'Properties' window for the dialog
3. at the top of that window is an ugly little button called 'Messages', click it.
4. that will show a long list of messages. find "WM_TIMER" and click in the white space to its right. an "Add Handler" option will appear.
intuitive!

Right key to the class,click "attribute", --->"message"--->"WM_TIMER"
::Settimer()
