I found it at Windows CE page. And I tried on Win XP.

Searching in Internet is like Searching a needle in hay stack
If u are unable to find something in MSDN or else where, 
just send a mail asking somebody to search MSDN for you. 
We will be happy to do that. At least we will be able to contribute to project like that

Now I use Windows XP Pro. 
Only in -multiwindow with "hide root" it hides from Task bar
But all other modes it is there in Taskbar.
Same case in WinXP Home, and Win2k (I tested 2 week back)

Yeah, its for tool bar. 
So for -nodecoration and -rootless you may be able to use that.
I am attaching a sample for this case

WS_EX_NOACTIVATE also wont show in task bar. 
But I dont know whether we will able to use it.
It may be useful in -multiwindow mode with show root,
to act like a desktop. And u can put wallpaper 
and root window click (????) on that.

You can also try SetWindowPos()
with Z-Order HWND_TOPMOST and flags SWP_NOSIZE | SWP_NOMOVE

I dont find any reason why "Exit Dialog" not to be TOPMOST

Style DS_CENTER | WS_SIZEBOX | WS_POPUP | WS_CAPTION | WS_SYSMENU 
should show only "Close (X)" button

But if you use WS_MINIMIZEBOX, maxmize button will automaticaly come.
(similary WS_MAXIMIZEBOX cause minimise button to show up)

Additionly if you want to disable "Close (X)" button with SysMenu/Left hand Icon

Use WS_SYSMENU in Style 
It will also bring up "Close(X)" button along with SysMenu
(M$ may have done this, to make old Win 3.1 pgm to show "Close (X)" button
If you remember there was no Close(X) in Win 3.1) 

and then do 

    case WM_INITDIALOG:

      hMenu = GetSystemMenu(hwnd, FALSE);
      EnableMenuItem (hMenu , SC_CLOSE, MF_BYCOMMAND | MF_GRAYED);

But again, if you want a "Close" option as menu Item, then add
      RemoveMenu(hMenu,   SC_CLOSE,   MF_BYCOMMAND ); 
      AppendMenu(hMenu,   MF_STRING,  IDC_MYCLOSE,    "&My Close");
