c# - Problem Creating Instances of ASP.NET User Controls Programmatically -

I am able to create control pro from the gramma without any problem using the code given below:

< Pre>

 FileListReader FReader = (FileListReader) LoadControl ("~ / Controls / FileListReader.ascx"); PhFileLists.Controls.Add (fReader); However, I would like to change the control so that I can give it a constructor like this:    Public FileListReader (Int32 itemGroupId, Int32 documentType, string header string , String Footer String, Bull is Administrator) {base.Construct (); This.itemGroupId = itemGroupId; This.documentType = documentType; This.HeaderString = HeaderString; This.FooterString = FooterString; This.isAdminUser = isAdminUser; }  
  And then I should be able to call control in this way: 
   FileListReader fReader = (FileListReader) LoadControl (typeof (FileListReader), New Object [] {Item Group ID, 6, "Cell Sheets", "End Lt; BR /> 
 AdManuser}};  
  However, when I do this, I always get an error that the control within the file control manager in my file has not been started and I get an empty reference error. So for example I have a  and  gt; & Lt; / Asp: label & gt;  is the control, when I try to set the text on the page_load method, what is the reason for it being generated? I felt that  base.Construct ()  must have solved this issue but it is not clearly.

  
  The proper way of a manufacturer's heir is as follows: 
   Class FileListReader: WebControl {Public FileListReader (Int32 itemGroupId, Int32 documentType, String Header String, String Footer, bool isAdminUser): Base () // and & lt; - Notice this heir {this.itemGroupId = itemGroupId; This.documentType = documentType; This.HeaderString = HeaderString; This.FooterString = FooterString; This.isAdminUser = isAdminUser; } // ... other code here ...  
  Does your constructor change to fix the problem?

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 ...
