Cheers NUL was what I was looking for. I've used it to exec stuff and get php to run straight past, and last night was sick of forgetting where to edit the dreamweaver config files every time I need to add a new type, as I want .cgi to be highlighted as php. I put this in a bat file, but both windows won't kick off at once:
"C:\Program Files\Windows NT\Accessories\wordpad.exe" "C:\winFiles\Macromedia\Dreamweaver MX 2004\Configuration\DocumentTypes\MMDocumentTypes.xml" > nul 2>&1
"C:\Program Files\Windows NT\Accessories\wordpad" "C:\Documents and Settings\s\Application Data\Macromedia\Dreamweaver MX 2004\Configuration\Extensions.txt" > nul 2>&1
Any idea if I can get it to not wait for the first one to close?
