Re: html browser preview help

Hi ken-93

Thanks again for your helpful reply.
I have tried to follow your advice & code but I still need some help.
(BTW O/S=Vista & browser=InternetExplorer8)

To open internet explorer from the shell> start iexplore.exe

From this I edited your .emacs defun code to:

(defun browse-file-url-ie-new-tab (url &optional new-window) 
  "Open the current file, the file associated with the current buffer, 
 in a new IE tab." 
  (interactive "i") 
  (unless 
      (string= "" 
               (shell-command-to-string 
                (concat "start iexplore.exe" buffer-file-name 
", new-tab)'"))) 
    (message "Opening in IE new tab: " buffer-file-name))) 
(setq browse-url-browser-function 'browse-file-url-ie-new-tab) 

When I try this I get a browser to open at my homepage. 
(I have tried to edit this in other ways but again with no success).

The code I have which opens my IE browser normally is:

(setq 
 browse-url-browser-function 'browse-url-generic
 browse-url-generic-program "C:\\Program Files\\Internet
Explorer\\iexplore.exe")

 (setq gnus-button-url 'browse-url-generic
 browse-url-generic-program "C:\\Program Files\\Internet
Explorer\\iexplore.exe"
 browse-url-browser-function gnus-button-url)

Any idea how I should proceed/what I can try to fix this please?
Many thanks & best wishes
