Generating Random Number Using RND Function And Randomize Statement
We will use RDN function to generate a random number. Our first example generates a random number between 1 ~ 10.
Example 1
<%@ Page Language="VB" Debug="true" %>
Sub Page_Load(Source as Object, E as EventArgs)
Dim i as integer
i = CInt(Int((10 * Rnd()) + 1))
example.InnerHtml = "Random Number : " & i
end sub
i = CInt(Int((10 * Rnd()) + 1))
In this example we put a limited number for our result. Here, 10 is the upperbound for our random number, Our lowerbound is 1. Becuase we do not want to generate a random number equals to 0 (zero). Our script will generate a random number from 1 to 10.
Now we will generate a random number using randomize statement. You will add only a line same code. Add 'randomize' code inside of your original code. Randomize generates a number from system timer, then RDN function uses this number to generate a random number. Therefore if you use 'randomize', mostly you will get more different numbers.
Example 2
<%@ Page Language="VB" Debug="true" %>
Sub Page_Load(Source as Object, E as EventArgs)
Dim i as integer
Randomize
i = CInt(Int((10 * Rnd()) + 1))
example.InnerHtml = "Random Number : " & i
end sub

Getting the primary key value of the record
Often, we need to insert a new record in a table with an autonumber
variable as primary key, and get the value of the automatically
generated primary key back. For instance, when we start a new session
for a user, and we need the sessionID to insert as a foreign key into an
order table or so.
Simple PHP SOAP example
This post will show a simple example of how to interpretate a WSDL file and a very simple, yet quick example of how to extract information from this file through PHP.
In this example I assume that you've already have SOAP enabled in your PHP configuration because this is beyond the scope of this example. If you're not sure, you can check your phpinfo file.
Using an alternate JSON Serializer in ASP.NET Web API
The new ASP.NET Web API that Microsoft released alongside MVC 4.0 Beta
last week is a great framework for building REST and AJAX APIs. I've
been working with it for quite a while now and I really like the way it
works and the complete set of features it provides 'in the box'. It's
about time that Microsoft gets a decent API for building generic HTTP
endpoints into the framework.
How to Convert a PSD to XHTML
