Microsoft Visual Studio 2010 SP 1 – Issues

Published on November 10th, 2011 by in General, MS Visual Studio

So, after I’ve installed (and deinstalled) SP1 for the first time, I have decided to give it another shot… Regrettably…

Here is, what I’ve experienced so far:

  • I’m not seeing “Hidden” Controls in the Designer anymore (I mean.. what the heck?! That my customers aren’t seeing them in a deployed application is perfectly fine, but why (at least) does no option exist to turn this on / off in the Designer?)
  • “Debugging-Tooltips” (or what should I call them?) are unstable… Mostly 90% of the time I want to look up a variable or property, no Tooltip opens on mouseover… Here you go, Immediate Window…
  • The XAML-Designer loads up way slower than before
  • The XAML-Designer occasionally crashes with an InvalidOperationException:
System.InvalidOperationException
Operation is not valid due to the current state of the object.

SHA1-Encrypting

Published on October 28th, 2011 by in C#, Snippets

There is only some slow blogging going on recently… So here’s something to fill the Lazyness-Gaps :) 

  1.         /// <summary>
  2.         /// Encrypts the specified Text to SHA1
  3.         /// </summary>
  4.         /// <param name="text">The Text to encrypt</param>
  5.         /// <returns>The SHA1-Encrypted text</returns>
  6.         public static string EncryptToSHA1(this string text)
  7.         {
  8.             SHA1 sha1 = new SHA1CryptoServiceProvider();
  9.  
  10.             byte[] arrayData = Encoding.ASCII.GetBytes(text);
  11.             byte[] arrayResult = sha1.ComputeHash(arrayData);
  12.  
  13.             string result = string.Empty;
  14.             string temp = string.Empty;
  15.  
  16.             for (int i = 0; i < arrayResult.Length; i++)
  17.             {
  18.                 temp = Convert.ToString(arrayResult[i], 16);
  19.                 if (temp.Length == 1)
  20.                     temp = "0" + temp;
  21.                 result += temp;

List of CultureCodes in C#

Published on October 19th, 2011 by in C#

A comprehensive list of culture codes used for localising and in conjunction with the CultureInfo class.

The CultureInfo class specifies a unique name for each culture, based on RFC 4646 (Windows Vista and later). The name is a combination of an ISO 639 two-letter lowercase culture code associated with a language and an ISO 3166 two-letter uppercase subculture code associated with a country or region.

What programming is all about…

Published on September 30th, 2011 by in Daily Life, General

Here are 14 Programming quotes selected from BVK Mohan’s blog (http://bvkm.wordpress.com/2010?/12/16/top-50-programming-quotes/).

Enjoy :)

1. “Always code as if the guy who ends up maintaining your code will be a violent psychopath who knows where you live.”
– Martin Golding

2. “To iterate is human, to recurse divine.”
– L. Peter Deutsch

3. “The trouble with programmers is that you can never tell what a programmer is doing until it’s too late.”
– Seymour Cray

4. “Debugging is twice as hard as writing the code in the first place. Therefore, if you write the code as cleverly as possible, you are, by definition, not smart enough to debug it.”
– Brian W. Kernighan.

5. “Most software today is very much like an Egyptian pyramid with millions of bricks piled on top of each other, with no structural integrity, but just done by brute force and thousands of slaves.”
– Alan Kay

6. “Measuring programming progress by lines of code is like measuring aircraft building progress by weight.”
– Bill Gates

7. “Sometimes it pays to stay in bed on Monday, rather than spending the rest of the week debugging Monday’s code.”
– Christopher Thompson

8. “I don’t care if it works on your machine! We are not shipping your machine!”
– Vidiu Platon.

9. “Walking on water and developing software from a specification are easy if both are frozen.”
– Edward V Berard

10. “Fine, Java MIGHT be a good example of what a programming language should be like. But Java applications are good examples of what applications SHOULDN’T be like.”
– pixadel

11. “I think Microsoft named .NET, so it wouldn’t show up in a Unix directory listing.”
– Oktal

12. “I have always wished for my computer to be as easy to use as my telephone; my wish has come true because I can no longer figure out how to use my telephone.”
– Bjarne Stroustrup

13. “Don’t worry if it doesn’t work right. If everything did, you’d be out of a job.”
– Mosher’s Law of Software Engineering

14. “In the one and only true way. The object-oriented version of ‘Spaghetti code’ is, of course, ‘Lasagna code’. (Too many layers).”
– Roberto Waltman.

Convert Image to Byte[]

Published on September 15th, 2011 by in C#, Snippets, WPF

Let’s get a bit more advanced – we’re now converting a WPF-Image to a byte[]. You can then store this byte[] in an MS-SQL Database, for example.

  1.         /// <summary>
  2.         /// Converts the specified Image to a byte[]
  3.         /// </summary>
  4.         /// <param name="imageToConvert">The Image you wish to convert</param>
  5.         /// <returns>A Byte[], containing the images Information</returns>
  6.         public byte[] ConvertImageToByteArray(Image imageToConvert)
  7.         {
  8.             BitmapImage bmp = imageToConvert.Source as BitmapImage;
  9.  
  10.             if (bmp != null)
  11.             {
  12.                 int height = bmp.PixelHeight;
  13.                 int width = bmp.PixelWidth;
  14.                 int stride = width * ((bmp.Format.BitsPerPixel + 7) / 8);
  15.  
  16.                 byte[] bits = new byte[height * stride];
  17.                 bmp.CopyPixels(bits, stride, 0);
  18.  
  19.                 return bits;
  20.             }
  21.             else
  22.             {
  23.                 return null;
  24.             }
  25.         }

Creating a Nice-Looking Filesize in C#

Published on September 13th, 2011 by in C#, Snippets

Let’s go ahead with a little Code-Snippet regarding the FileSize in C#. Sometimes you need to display a “nice file size” – values like 14865343435 Bytes are absolutely useless for Userfriendly Interfaces…

  1. 		/// <summary>
  2. 		/// Creates a nicer FileSize from bytes
  3. 		/// </summary>
  4. 		/// <param name="size">The Size to Parse</param>
  5. 		/// <returns>The converted FileSize, including the SizeType (KB, MB, ...)</returns>
  6. 		public static string CreateNiceFileSize(double size)
  7. 		{
  8. 			int run = 0;
  9. 			string[] sizes = { "B", "KB", "MB", "GB", "TB", "PB", "EB" };
  10. 			while (size >= 1024)
  11. 			{
  12. 				size /= 1024;
  13. 				run++;
  14. 			}
  15.  
  16. 			return (Math.Round(size, 2) + " " + sizes[run]);
  17. 		}

Console.WriteLine(“Hello World!”);

Published on August 12th, 2011 by in General

Welcome to my new blog. I’ve thought for quite a while about starting a blog based on some advice from my friend Felix, but I finally got around to it. I plan to write on topics relevant to Coding, C#, Visual Studio and general Microsoft-Stuff. I’ll try to keep away from strictly technical topics, as there are many good blogs out there already.

Please feel free to send suggestions about topics you would like to hear about and areas, where I can get a little closer to perfection…
