DateAdd : reusable Javascript function

 

While looking for a Javascript equivalent of DataAdd VB or SQL method, I came across this function which is working flawlessly. Please visit the forum post to view it directly and also as follow:

   1: function DateAdd(timeU,byMany,dateObj) {

   2:     var millisecond=1;

   3:     var second=millisecond*1000;

   4:     var minute=second*60;

   5:     var hour=minute*60;

   6:     var day=hour*24;

   7:     var year=day*365;

   8:  

   9:     var newDate;

  10:     var dVal=dateObj.valueOf();

  11:     switch(timeU) {

  12:         case "ms": newDate=new Date(dVal+millisecond*byMany); break;

  13:         case "s": newDate=new Date(dVal+second*byMany); break;

  14:         case "mi": newDate=new Date(dVal+minute*byMany); break;

  15:         case "h": newDate=new Date(dVal+hour*byMany); break;

  16:         case "d": newDate=new Date(dVal+day*byMany); break;

  17:         case "y": newDate=new Date(dVal+year*byMany); break;

  18:     }

  19:     return newDate;

  20: }

Using a Stored Procedure in Entity Framework 4

If you have worked with LINQ and added stored procedures to it, it would seem obvious to be able to it the same way in Entity framework.

In LINQ all you had to do is to drag the stored procedure from your Server Explorer respective data connection on your model diagram.

In entity framework 4, there are few steps and they are different.

1. On your entity diagram in visual studio, right click and choose Update Model from database.

2. Add your stored procedure from the wizard. What it does, it adds the proc to your diagram. Its not visible in .Net code yet.
If you go to Model Browser > {EntityModel}.Store > Stored Procedures, it should be visible in there now

3. Right click, Add > Function Import. Complete this according to your requirement, name of the proc you want to see in .Net, which stored proc it maps to and what is the collection it returns etc.

After step 3 you can access access the proc using an instance of context.

Extracting tags from xhtml content

There are two ways of doing it. One is the dirty way, using Mid function in VB.Net or IndexOf string method but the more appropriate way would be to use regular expressions.

Following code will get you title using regular expression

Regex regex = new Regex("<title>(?<title>.*?)</title>", RegexOptions.IgnoreCase);
Match titleMatch = regex.Match(html);
string title = titleMatch.Groups["title"].Value;

Following code will get you meta tag My_Meta

Regex regex = new Regex("<META +NAME=\"(?<name>My_Meta*?)\" +CONTENT=\"(?<content>.*?)\" */?>", RegexOptions.IgnoreCase);

Match metaMatch = regex.Match(html);

title = metaMatch.Groups["content"].Value;

Saving objects using Entity framework

TableClass tableObject = new TableClass();
tableObject.property1 = "Hello";
tableObject.proeprty2 = "World";

// NOTE: make sure to use the same instance of entityContextObject which was used to populate the tableObject (e.g. updating back to database)
entityContextObject.AddToTableClass(tableObject);
entityContextObject.SaveChanges();

Accessing email settings from web.config

Rather than using appSettings, a section from webconfig is a better use for email settings which gives you typed properties in .Net code.
