Searching for files that DONT contain a certain string

[durbs]

Hi, i need to search a large amount of text files (aspx.vb) for all files that DONT contain a certain text string. All the tools i've got only seem to be able to search for all instances of a certain string (normally use the excellent Textpad for this sort of thing).

Anyone know a tool that i can point at a directory and it'll tell me all files of a certain type that dont contain the word 'Apples' for example?

Ta bledd, thought initially that would be no good as i read the line 'Search for a text string in a file' and seeing as theres 300+ files to search against i didnt fancy the hassle of scripting it to loop through them all. Turns out it can indeed scan a directory though so that'll do the trick!
