Online Developer Tools

No Comments »

Here’s something that all you, my fellow C# developers, will find useful. Yesterday a company called Browserling announced that they’re launching a network of online developer tools.

If you haven’t heard about Browserling then you should check them out. They’re a friendly and fun cross-browser testing service and they’ve created and open-sourced over a hundred projects, including browserify for node.js.

Online developer tools network is a collection of websites where each website focuses on a single category of developer tools. Right now there are four websites in the network and they’re releasing 30 more websites over the next couple of years.

All websites in the network are ad-free. The reason why Browserling built this network is because their developers got fed up with other online services that offer similar tools. They were often filled with ads, popunders, blinking buttons and other crap. Browserling’s developers had had enough of this and they decided to create their own utilities that just work in your browser and do the right thing.

Let’s take a look at each site in more details.

Online String Tools

Online String Tools has hundreds of tiny string utilities for converting strings, generating strings, encoding/decoding strings, filtering and replacing strings and more. All string utilities work right in your browser. There is no server-side processing going on and everything is super fast.

Online JSON Tools

JSON Tools for Developers

Online JSON Tools has two dozen utilities for working with JSON config files and JSON documents. Just like string tools, JSON tools work in your browser and are powered by modern JavaScript code, which makes them very fast. You can convert JSON to various data formats, encode and decode JSON, and compress, validate and prettify JSON.

Online XML Tools

Similar to string and JSON tools, this website offers two dozen utilities for working with XML configuration files and XML documents. All tools on this website also work inside your browser and nothing gets sent to the server. You can pretty much do all XML tasks with these tools. For example, you can compress XML, prettify XML and validate XML documents, and you can also convert XML to other data formats, such as YAML, TSV, CSV, JSON and Base64.

Online CSV Tools

Online CSV Tools offers over two dozen different utilities for working with CSV data files. All CSV data processing happens in the browser and it’s super fast. You can convert CSV to a bunch of other data formats, like JSON and YAML, then you can work with CSV columns and rows. You can insert rows, swap columns, as well as change CSV delimiter and change quoting of CSV fields.

What’s next?

Browserling loves marathons. They will be adding 30 more websites to their network over the next 5 years. Here are some of the other sites they will be launching:

  • Online BROWSER Tools – A collection of browser/web developer tools
  • Online YAML Tools – A collection of Yet Another Markup Language tools
  • Online TSV Tools – A collection of Tab Separated Values tools
  • Online IMAGE Tools – A collection of image editing tools
  • Online AUDIO Tools – A collection of audio editing tools
  • Online PDF Tools – A collection of PDF editing tools
  • Online CRYPTO Tools – A collection of cryptography tools
  • Online RANDOM Tools – A collection of randomization tools
  • Online FILE Tools – A collection of file editing tools
  • Online TIME Tools – A collection of various time and date tools
  • Online LIST Tools – A collection of tools for working with data lists
  • Online CSS Tools – A collection of CSS tools
  • Online JS Tools – A collection of JavaScript tools
  • … and more websites!

How to Initialize Flags Enumerations in C#


I have a friend who is just starting to learn C#, so I am getting some interesting questions whose answers seem obvious to me but apparently not to beginners.  Today I answer the question: What’s the best way to initialize Flags enumerations in C#?

As a quick review, here is how Microsoft describes the Flags enumeration:  “You can use an enumeration type to define bit flags, which enables an instance of the enumeration type to store any combination of the values that are defined in the enumerator list.  (Of course, some combinations may not be meaningful or allowed in your program code.)  You create a bit flags enum by applying the System.FlagsAttribute attribute and defining the values appropriately so that AND, OR, NOT and XOR bitwise operations can be performed on them.”

In other words, each enumeration value must correspond to a single, unique bit.  So one way to initialize flags is to use integers that are a power of 2.  The disadvantage of this method is it’s not easy to see which bit is being set, and errors might creep in enumerations with many flags, especially when you start getting up into the range of 16384, 32768, 65536, and 131072.  But there is nothing inherently wrong with this approach either:

public enum DaysOfTheWeek
	None = 0,
	Sunday = 1,
	Monday = 2,
	Tuesday = 4,
	Wednesday = 8,
	Thursday = 16,
	Friday = 32,
	Saturday = 64,

Zoom the View in Visual Studio

No Comments »

I was using Visual Studio on my laptop when suddenly the font in the code editor got so small I could barely read it.  I figured I must have engaged some obscure key sequence, so I did a little research and discovered there are many ways to change the zoom level in Visual Studio:

Keyboard Shortcuts

  • To make the font larger, press CTRL+SHIFT+PERIOD
  • To make the font smaller, press CTRL+SHIFT+COMMA

Keyboard+Mouse Shortcuts

  • To make the font larger, press & hold the CTRL key while scrolling the mouse wheel up one click
  • To make the font smaller, press & hold the CTRL key while scrolling the mouse wheel down one click

Note this also works with the trackpad on most laptops.  Sliding your finger up or down along the right edge of the trackpad is the same as scrolling the mouse wheel.  By the way, I had the CTRL key pressed while I slid my finger down along the right edge of the trackpad, and this is how I accidentally made the font really small.  Also note that each click increases or decreases the font size by 10%.

C# Modeling Tools


C# modeling tools help you model, visualize, analyze, understand and document C# source code.  Most modeling tools use the Unified Modeling Language (UML), which is a standardized way to create visual models from object-oriented source code.

Following is a list of modeling tools that run on Microsoft Windows and model software written with the C# programming language.  Prices listed are direct from the manufacturer for a single license of the “Professional Version” which includes C# round-trip engineering.  This means the modeling tool can read C# source code and generate models, allow the user to make changes to the model, then automatically generate the updated C# code.  Foreign prices are converted to U.S. Dollars at the current exchange rate. 

Please comment with any corrections or additions, as I will keep this list updated.

Google Considered C# as the Native Language for Android


Wow, I nearly fell out of my chair when I read this little gem on TechCrunch:

Android chief Andy Rubin wrote in a 2005 email, “If Sun doesn’t want to work with us, we have two options: 1) Abandon our work and adopt MSFT CLR VM and C# language – or – 2) Do Java anyway and defend our decision, perhaps making enemies along the way.”

Imagine how different the world would be today if Google had chosen .NET instead of Java as the native development framework for the Android mobile operating system…

C# Custom Enumerators Made Simple with the Yield Keyword


An enumerator enables you to iterate over a collection in a foreach loop.  You can use foreach to iterate over all C# collection classes, because all C# collection classes inherit from the IEnumerable interface (regular or generic).  IEnumerable contains the GetEnumerator method, which returns an enumerator.

Occasionally you may find a need to create a custom enumerator, which used to be somewhat of a challenge until the yield keyword was introduced.  Here is how Microsoft describes yield:

The yield keyword signals to the compiler that the method in which it appears is an iterator block.  The compiler generates a class to implement the behavior that is expressed in the iterator block.  In the iterator block, the yield keyword is used together with the return keyword to provide a value to the enumerator object.  This is the value that is returned, for example, in each loop of a foreach statement.

So rather than creating your own enumerator class and managing the enumeration state — which is time consuming and tricky — you can simply write the enumeration logic in the GetEnumerator method, and the yield keyword will automagically wrap your code in a handy-dandy enumerator.

Apparently C# Doesn’t Suck


YourLanguageSucks is a wiki on that lists reasons why the most popular programming languages suck.  There are long lists of reasons why Java, JavaScript, C++ and PHP suck.  But the list for C# is very short:

  • Supports ‘goto’.
  • Two distinct sets of collections: non-generic and generic.  Stack and Queue have the same name in both their generic and non-generic flavors, but then we have Hashtable (non-generic) and Dictionary (generic).

The first reason is easy to discount: just avoid using goto!  The second reason is valid, but not really an issue if you use only generic collections, as I do.
