The following page : http://msdn2.microsoft.com/en-us/library/6f01ek09.aspx
says that __event -based event handling is deprecated. In that case, what is the best way to do event handling?
I have a class HWClass, that talks to a hardware device. Several other classes need to read from this hardware device. However, the reading is asynchronous and HWClass needs to notify the calling object if the reading process is finished.

Use the event_source and event_receiver attributes instead.

but you still have to use __event and __hook with these attributes. plus, they are optional in native C++. or am i missing something?
|

Yeah, sorry my memory was a little vague there 
The __event and associated keywords are the .NET 1.1 style of event handling. .NET 2.0 uses the event keyword instead, and is only supported for managed objects. If you're wanting to use events with native C++ objects (which they were never designed for), I'd recommend using callback functions or functors instead.

i guess back to the old solution. i was aware of functors, but just saw how convenient the __event style was.
thanks!

I code to display the bitmap,
the situation is like , i got a background bmp , and later a transparent bmp (Let's say a character bitmap) to cover onto the background.
I wonder why the background bmp is displayed well n refreshed at every rate , but the character bmp will display in a flashing way.
Is there anything to fix it?
And yet i tried another way , i created the character's DC and HBITMAP directly inside the background's DC but not in the CClientDC. It won't flash but it run very slow when it's bein displayed.
Hope to seek for some guides.
thanks for guides... =)

I have written an application. After clicking cross (close) Button, i have to execute some code (i.e to call fclose() function). Where should I write the code? Please help me regarding this.

In your WM_CLOSE handler.
If your using MFC you can override OnClose for your view/dialog, or place your code in the ExitInstance member of your CWinApp derived class.
Or you could put your code in your objects ~destructor.

Hi,
As a first step you need to register all the components and add necessary permissions to access from VC++, i think it should be DCOM components and there will be two .exe files. After these registration you will get Interop DLL's. From there it will be general programming structure it will give response in the form of XML further some PDF's will be available with QB for developers.
