c# - Entity framework issue with WCF and IIS -

September 15, 2013

I have a WCF service in a machine, an MS SQL database and the development environment of Visual Studio 2008 I iis 7 Operating System with Windows Server 2008 is IIS 7 hosts my WCF service and the service is connecting to the database using the Microsoft Entity Framework. Currently, I use the WCF Test client program from Microsoft WCF Received'm testing.

The problem is that when I declare a unit like this in my WCF method:

  newestdbentte db = new newtte dbestentes ();

If I'm connecting to hosting WCF service on IIS, then WCF service client shows error.

This error message is in the form of a WCF service client:

Failed to apply the service The possible cause: The service is offline or inaccessible; Client-side configuration does not match proxy; The current proxy is invalid View the stack trace for more details. You can try to recover by starting a new proxy, restoring the default configuration, or refreshing the service.

I know that this line throws an error because if I take this line away, then WCF completes the call

I have a debugger (WCF service customer IIS is connected to ASP.NET Development Server, and tried to check the WCF service by running this line of code

.  NewTestDBTTs DB = New NewTestDBTT ();

Run without error Does anyone know why this happens?

Thank you very much. Your WCF service is hosted in IIS - but have you been using relevant web.config

 EF4 the connection string is copied, also ??   If only the object context ( NewTestDBEntities ) stops with the bat, it is usually because the connection information is not available for your host application (here: IIS).

Short URL Outbound Link Tracking in PHP and MySQL -



    I have a site that reduces the link based on this topic. I decided that it would be great if users click on a small URL, like HootSuite users can track their links. I currently have a database in which the short URL is placed with the actual URL and this click count will ideally update the click count column when that small URL is accessed by an external user.   In short, I am looking for a PHP / MySQL solution so that many small URLs can be clicked. . Any additional information gathered from the clicks will also be highly appreciated.      I'm assuming you followed the PHP version of your tutorial. If so, look at listing for service.php under "service of small URL". In section round line 11 where it determines the position of 301, you can redirect with the database update. Something like    $ query = mysql_query ("update`" $ database. "` .```_AL_DIRED`Set count = count + 1 where` small '=' ".mysql_escape_string ($ short) , $ Db); $ Line = ...

php - How do I set up pagination for an image gallery with image
thumbnails? -



    I have two tables:    gallery id | Name | Details Image ID | Title | Caption | Gallery ID    By listing all thumbnails or paging through thumbnails I got the code to create a simple image gallery. However, what I need to do is here something like gallery here Only completes without javascript and ajax:     I want a selection number to show below the main image as soon as the user clicks the thumbnail, the page Selected new Highlight the image and the series of thumbnails on boto goes forward one by one if its not the last image.   How do I do this? Do I need a quick and dirty way to do this? I am using php and mysql for the database here - just need code to show 'paged' images below the main image. I know how to install everything i.e. Thumbnail size etc ...      I do not know the number of your rows in MySQL for T-SQL As there is a ROWNUMBER () function, but to do this, it is a smart way to sequential numbering of your images in the database. From there, you ask something ...
