vb.net - Brute force MD5 hash in Visual Basic -

i have made program converts string hash using md5 algorithm.

   public shared function getmd5hash(byval strtohash string) string     dim md5obj new system.security.cryptography.md5cryptoserviceprovider()     dim bytestohash() byte = system.text.encoding.ascii.getbytes(strtohash)      bytestohash = md5obj.computehash(bytestohash)      dim strresult string = ""     dim b byte      each b in bytestohash         strresult += b.tostring("x2")     next      return strresult end function  private sub button1_click(byval sender system.object, byval e system.eventargs) handles button1.click     textbox2.text = getmd5hash(textbox1.text) end sub 

but have added button use brute force find original text when md5 hash given.

what code can write in button systematically try every word/number , check against original hash?

what code can write in button systematically try every word/number , check against original hash?

looking @ current code , enormous effort create button, recommend, , might sound bit crazy, recommend code within button .... vb.net
