Pluralisation in C# and JavaScript

Pluralisation is the act of making a singular word to its plural equivilent. For example, baby should equal babies and student should equal students.

I was thinking how difficult this would be to do in code without asking users to type both singular and plural in.

So I have come up with the following function that should convert a given word into its plural equivilent. It should also take care of if a word is already plural. I have written both methods in C# and JavaScript below. There are few changes between them.


public string Pluralise(string word) {
if (word[word.Length - 1] == 's')
return word;

if (name[word.Length - 1] == 'y' && word[word.Length - 2] != 'e')
return word.Substring(0, word.Length - 1) + "ies";

return word + "s";
}


JavaScript


function Pluralise(word) {
if (word[word.length - 1] == 's')
return word;

if (word[word.length - 1] == 'y' && word[word.length - 2] != 'e')
return word.substring(0, word.length - 1) + "ies";

return name + "s";
}


How to update AppSettings programmatically

You can approach this like:

string newSetting = txtSetting.Text;
Configuration config = System.Web.Configuration.WebConfigurationManager.OpenWebConfiguration("~");
AppSettingsSection section = (AppSettingsSection)config.GetSection("appSettings");
section.Settings["AnAppSetting"].Value = newSetting;
config.Save();

Compile an ASP.net usercontrol into a DLL

Recently I have been using the ASP.net AJAX Toolkit and one of the best things about this toolkit is that the controls are compiled into one nice sized DLL.  This left me thinking, why don’t I create my own library of reusable usercontrols and compile them into a single DLL instead of including the seperate files together.
I found a nice tutorial on how to do this here.

Here is another tutorial I found that shows you how to create server controls that can be added to the toolbox here.

Regular Expression Validator – Validating a user inputted time (24 hour format)

I have a text box that the user inputs a time like “22:30″. But I don’t want the page to postback unless the input is valid. This is where the RegularExpressionValidator comes in to play.

What is the RegularExpressionValidator?
Basically, it is a control that you add to the page just like a button or text box. When you declare it in markup it adds client side code that validates this control on the client side and will cancel the postback if it is not valid.

Here is the the code I used:

<asp:TextBox ID="txtStartTime" runat="server" />
<asp:RegularExpressionValidator ID="regexStartTime" ControlToValidate="txtStartTime"
     ValidationExpression="^([0-1][0-9]|[2][0-3]):([0-5][0-9])$" ErrorMessage="Input valid date" runat="server" />

As you can see, I have a text box declared and under it I have declared a RegularExpressionValidator. The attributes I have used are:
- ID = a unique id for the control on the page
- ControlToValidate = the id of the control to validate
- ValidationExpression = the regex to use to validate the input
- ErrorMessage = your custom error message if validation fails

The regex I used to validate a 24 hour time input (HH:MM) is:
^([0-1][0-9]|[2][0-3]):([0-5][0-9])$

I was recieving this error in ASP.net.  The cause of the error was the following line:

Response.Headers.Add(“content-disposition”, “inline; filename=\”somefile.txt\”");

 

The workaround I used for this was to use the AddHeader method instead:

Response.AddHeader(“content-disposition”, “inline; filename=\”somfile.txt\”");

Make sure AjaxControlToolkit.Properties.Resources.NET4.resources was correctly embedded

I’ve been playing around with ASP.NET AJAX recently and decided to try out a few controls in the AJAXControlToolKit and I received this message the first time I used the AsyncFileUpload control.

 

The solution was to include the following, somewhere on the same page as the AJAX control

<asp:ScriptManager ID=”ajaxScript” runat=”server”>
</asp:ScriptManager>

Regex to replace urls with hyperlinks in text

Use the following code to convert urls in text into html hyperlinks.  The code also fixes a bug that is in a lot of resources out there where if a url is at the end of a sentence ending with a full stop, the full stop would be included.

Here is the fully working method:

function replaceURLWithHTMLLinks(text) {
  var exp = /(?:^|[^"'])((ftp|http|https|file):\/\/[\S]+(\b|$))/gi
  return text.replace(exp, " <a href='$1'>$1</a>");
}

Error 5 : Access Denied when starting windows service

I resolved this issue by issuing the correct file permissions on the root directory of the service for the user ‘SERVICE’.
That is all.

Adding SSL to IIS 7

I come across a problem today where we exported a few SSL certificates off one of our servers and imported it on to another IIS 7 server.

For some reason we were getting an error to do with a chain of certificates when assigning https bindings.
The solution was to install SSL123 (based on Certitificate subject when viewing the certificate on IIS 7) from

https://search.thawte.com/support/ssl-digital-certificates/index?page=content&id=AR1384&actp=RELATED_RESOURCE

 

We installed the CA Bundle for SSL123 and reassigned the SSL certificates to the appropriate sites with no issues.
