c# - Overloaded VB.NET extension method in class library -

It seems that there are problems with my written library of written extensions in VB.NET.

I2 overloaded extension methods crop ().

When I refer to Lib from the VB.NET project, I see them. If it refers to the C # project, then I can not see them.

What's going on?

It works like this:

In C # When you call a method with a outside or ref parameter, the compiler will call out or riff Keyword needs to be repeated. This is because it does not make any difference to the language whether the variable is already initialized or not.
In VB.NET, when you call a method with the ByRef parameter, the compiler lets you repeat the ByRef on the calling logic Not necessarily, this fixes it for you because the language does not make any difference whether the variable is already initialized or not.

  Therefore, VB.NET can easily solve an extension method by using  ByRef . , Because there is only one possible way in which it can be called. However, C # does not know what to do because by saying that there is no syntax for calling method using  outside  or  riff . 
  All you can do is: 
   Write your extension methods again to use the  ByVal  parameter wherever possible. 
  If this is not possible, you get stuck with them in normal ways like calling C #.

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 ...
