Starting in Win98 sp2, Windows began making it difficult for one program to grab control (keyboard/visual focus) from another program.  It makes a lot of sense:  If you are working in a wordprocessor, you don't want some program to jump up and start eating your keystrokes (especially if it is one of thos banner ads!).  There is also a security consideration:  A program could lurk in the background waiting for a password prompt to appear, take the focus, save the keystroeks, then disappear.

So, unless your program owns the 'Foreground Window' any MessageBox that it pops up will be behind whatever program is currently in front.  

You can try calling SetForegroundWindow just before popping up the MessageBox.  That will cause your taskbar button to flash (indicating 'hot' activity) and if the user clicks your taskbar button, the Messagebox will appear in front.

with ur own dialog box or message window u can use following function to place ur window at the topmost position without disturbing or changing ur focus from other applications.
(like MSN Messenger popup messages):

BOOL SetWindowPos (
const CWnd* pWndInsertAfter,
int x,
int y,
int cx,
int cy,
UINT nFlags );

for example:

SetWindowPos(&wndTopMost,0,0,200,100,SWP_NOACTIVATE);

'wndTopMost' will place ur dialog box or Window at the topmost level, and 'SWP_NOACTIVATE' will prevent shifting ur focus from any other application.

i hope this will help u.

good luck
