Dear Sir, I had read the PHP online manual and tried to create a Word application from my PHP code. I am now using Vista Business. Funny thing is: $word=new COM(?word.application?); Works fine under my development IDE (PHPED) but when I tried to load it in FireFox or IE (even with ?Run as Administrator? option), ti shows the below error msg: atal error: Uncaught exception 'com_exception' with message 'Failed to create COM object `word.application': ¾Ü¾ø·ÃÎÊ¡£ ' in F:\Books.web\php\spellcheck.php:4 Stack trace: #0 F:\Books.web\php\spellcheck.php(4): com->com('word.applicatio...') #1 F:\Books.web\php\spellcheck.php(41): SpellCheck('Hellu world. Th...') #2 {main} thrown in F:\Books.web\php\spellcheck.php on line 4 Can you help? Rgds! Taylor
