February 15, 2013

How to pass the null value for the database field type of the image I am trying But am receiving an error:

  if (photo) cmd.Parameters.AddWithValue ("EPhotograph", img); And CMD. Parameter. Edvat Value ("Epotograph", ""); If (signal) CMD Parameter. Advant Value ("signature", sign); And CMD.Pameters.Advith Value ("Aspiration", DBINUL.VIL); Please try entering a blank instead of

apache - How to do an URL rewrite that works with a
pre-existing .htaccess file? -



    I have a platform that is currently available through the URL:    Www.websitecom / index.php? App = forum    Instead, I want people to be able to go here:      & lt; Ifmodule mod_rewrite.c & gt; Option - Multi Views RewriteEngine RewriteBase / RewriteCond on% {REQUEST_FILENAME}! -f Rewrite Convert% {REQUEST_FILENAME}! -d rewriteable /index.php [L] & lt; / IfModule & gt;    It seems that it should be possible, but I'm not sure how to do it.   Thank you!      This has not been tested, but something like that should be done. Add it before the first Rev.Directivity.

By doing this:    301 / redirect the forum "http://www.website.com/index.php?app = forum    However, it seems that you want to make a proper rewrite, so the first option is better,
