Considering that I want to communicate between two processes on the same system, among the existing IPC mechanisms like shared memory, DDE, windows sockets, pipes, RPC etc.which is the best technique for IPC. The priority being security of data being exchanged, and the second priority being speed..
Thanks.

With processes on the same machine, I use shared memory since it's really simple to set up and access.

ok.. but is shared memory a secured way for IPC between processes or windows sockets a better way for IPC ?
Thanks

A shared memory section can be secured with an ACL. If at all possible, don't use a named section (which can be spied on and discovered). Use an unnamed one and communicate the name between the processes some other way. This was discussed on Raymond's blog[^] a while ago, you should be able to find it with a search.
As for sockets, I don't know off-hand since I don't do much work with sockets.

Hi.
I have a ready made menu IDR_MAINFRAME created by AppWizard.
So my problem is to load this menu on the Dialog box at the upper right portion of dialog window.
Thanks

Right click on the dialog box, take properties. You can find a combo box called, Menu. Select IDR_MAINFRAME from the combox. close the properties dialog and build the project.

Hi Nave.
Mannn that was easy wasn't it. Thanks.
But my requirement is to load this menu dynamically. I mean depending upon the requirement, I want to keep this menu changing.
i.e. For situation -->1 menu = IDR_MAINFRAME
For situation -->1 menu = IDR_ANOTHER
and so on....
Thanks

ok.
1. The create a member variable of class CMenu in your dialog.
2. In the Oninitdialog function, call LoadMenu with the resource you want( IDR_MAINFRAME or IDR_ANOTHER )
3. Now call SetMenu function and pass the pointer of the CMenu object.
eg .
m_Menu.LoadMenu( IDR_MAINFRAME );
SetMenu( &m_Menu );

if the file is unicode, Only thing you have to do is to pass a wchar_t pointer to the read function.

yes. If u do so, you will get the unciode string in the buffer. And What you want is to display it in the edit or some other controls, you neeed to define _UNICODE in your project settings
( Project->settings->Preprocessor definitions )

overide the PreTranslateMessage function of the main dialog and handle the WM_WINDOWPOSCHANGED messages of the child windows.
