DNN Custom Error Pages

[Custom Errors] 

Default error pages may expose a lot of information, Like the language and the server you use, and such Info. could be used by malicious users to attack your site and your server.

Also default error pages look very ugly and outdated design, which may harm your brand.

So It's always recommended to use custom error pages..

So, How Could I display a custom error page in DNN when error occurs ?

To Disable DNN Error Handling, and Let Errors Bubble..

Host Settings >> Appearance >> Un-Check "Use Custom Error Messages? "

To Redirect Users To, Can be aspx page, but I prefer HTML

Then Create HTML Page at the root with Style

Then in Enable CustomErrors in Web.Config :

    <customErrors mode="On">

      <error statusCode="500" redirect="/MyCustomError.html"/>

      <error statusCode="404" redirect="/MyCustomError.html"/>

      <error statusCode="403" redirect="/MyCustomError.html"/>

    </customErrors>

  

Also You can Override IIS Error Pages and Redirect to your Custom Error Pages using the below web.config snippet

    <httpErrors>
      <remove statusCode="404" subStatusCode="-1"/>
      <error statusCode="404" prefixLanguageFilePath="" path="/MyCustomError.aspx" responseMode="ExecuteURL"/>
      <remove statusCode="403" subStatusCode="-1"/>
      <error statusCode="403" prefixLanguageFilePath="" path="/MyCustomError.html" responseMode="ExecuteURL"/>
    </httpErrors>

Post to twitter programatically with 3 lines of Code!

1. Create a new web application
2. using Nuget manager, download/install Tweetsharp
3. Create a twitter application by visiting https://dev.twitter.com/apps/new
4. Go to your twitter app settings, and make sure it's a read/write app
5. Go to "Reset Keys" tab and reset keys, so the permission of read/write works with the new keys
6. Generate Access Token and the first tab in your twitter settings
7. Write the following Code, *Replace Dashes with your app keys, from the previous steps

======================================

using TweetSharp;

        //Store Keys
        string consumerKey = "-------";
        string consumerSecret = "-------";
        string accessToken = "-------";
        string accessTokenSecret = "-------";
        //Authenticate with twitter as your app.
        var service = new TwitterService(consumerKey, consumerSecret);
        service.AuthenticateWith(accessToken, accessTokenSecret);
        //Post Tweet
        var status = service.SendTweet(new SendTweetOptions { Status = "My Second #Tweet from Code :D" });

======================================

-- You can use the status variable to know the id of you posted status etc.

Less for Dot Net - Asp.net

Introduction

Just hit an interesting utility, LESS Compiler for .net (asp.net)
So you can leverage the power of less (Dynamic CSS) in your .net web applications

Usage

Just add the following to the Web.config

<add type="dotless.Core.LessCssHttpHandler,dotless.Core" validate="false" path="*.LESS" verb="*" />

<section name="dotless" type="dotless.Core.configuration.DotlessConfigurationSectionHandler,dotless.Core" />

So, now you added a handler for .less files

Then configure it

<dotless minifyCss="false"
 cache="true" />   

*You can also use it from the code

Less.Parse("div { width: 1 + 1 }");

which will produce 

div {
  width: 2;
}
