How can the cmd window be hidden?

[zhang listar]

Hi, all.
I am using gnu global with gvim on windows 7.
It woks fine and but a small problem bothes me.

I write the following code in vimrc:

au BufWritePost *.[ch],*.cpp call UpdateGtags(expand('<afile>'))
function! UpdateGtags(f)
     let dir = fnamemodify(a:f, ':p:h')
     exe 'silent !cd ' . dir . ' && global -u &> /dev/null &'
endfunction

But when I try to save content to gvim, a black window of cmd blinks,
and disappears.
I know it's vim calls it.

I want to let the cmd window run in the background. How can I do it?

Thanks in advance.

You can use !start /min or !start /b to run an asynchronous task minimized or with no window, respectively. If you do this, you may want to call back into Vim with the client-server function to let Vim know you're done. See:

Use system()

Thanks for your attention.
The plugin asynccommand is good.

Thanks a lot.
But it is the same using system()-a black window blocks gvim and
execute the command.
