sql server - Unable to connect to SQL LocalDB -

I have a basic C + + app inside which I am trying to connect to local DB example using ADO I am By manually starting my example, I can run sqllocaldb info v11.0 and see that the database instance is running.

My code is as follows.

  ADO :: _ Connection PTR connection (__Eidof (ado :: connection)); SpConnection-> Open (L "Provider = SQLNCLI11; Server = (LocalDB) \\ v11.0; Integrated Security = True", L "", L "", 0); The error code is DB_E_ERRORSOCCURRED (0x80040e21) and error message  Multiple-phase OLE DB operation errors are generated. If available, check the value of each OLE DB status. No work was done.    
 I have been able to successfully connect to the database using SQL Server Management Studio and I have tried to specify this with and without the connection string provider as well as an initial list.   
 
  I get my issue security should be set to  sspi  shown below.  
  ADO :: _ Connection PTR spConnection (ADO :: Connection); SpConnection-> Open (L "Provider = SQLNCLI11; Server = (LocalDB) \\ v11.0; Integrated Security = SSPI", L "", L "", 0);

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.    RewriteRule ^ forum $ /index.php?app=forums    Alternatively, you redirect from a 301 / forum to index.php URL .   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,
