Well.. what have you tried? Why would you put a string in a byte array? What event is supposed to trigger this?

[DamianMRLY]

Well eventually i want to read an file and determine the frequenty of all bytes for my Huffman algorimth

Textbox has a .Text property - That's how you get the text that is in the textbox.

It would therefore be a safe assumption that you haven't really taken any time to learn about C#. This is something covered by the 3rd chapter in any "Learn C# in 30 days" type of book.

As another expert here told another student (so well that he deserves credit for it):

Curtis Rutland, on 09 July 2012 - 01:38 PM, said:

I hate to be the bearer of bad news, but there's a fundamental problem here: we're not a "intro to programming class" and we never can be. We can help you with specific problems, but what you're missing is the basic foundation. Go back to your instructor and explain to him/her that you don't understand and need help. Talk to your classmates. Find someone who can go over the book with you, in person, so you can understand what you are missing.

For now, you just need to work on learning the foundation basics. Don't try to architect programs until you are ready.

Plan your study route:
There are three routes people seem to take when learning programming.

• Just start trying to create programs
  
• Start taking apart other programs and try to figure out the language by reverse engineering
  
• Follow a guided learning course (school or self-teaching books)

For the life of me I can't figure out why people try 1 & 2. I strongly suggest taking the guided learning approach. Those book authors go in a certain order for a reason: They know what they're doing and they know the best order to learn the materials.

• First learn the language by working 2-5 "Learn C# in 30 days" type books cover to cover.
  
• Do a dozen on-line tutorial projects where you build what you're told to build, the way you are told to build it WITH AN EXPLANATION OF WHY so you can learn.
  
• Learn to plan before you type.
  
• THEN you start designing software with a purpose.

I don't learn from reading books: I learn by doing.

Spoiler

Total honesty here: That is either B.S., you haven't really tried, or this is the wrong career field for you so bail out now.
You can try to learn C# by dismantling snippets and googling terms - basically you can take a hit-n-miss, shotgun approach. But honestly, just typing away and seeing what pops up in Intellisense is going to make your self-education take 20 years. You can learn by trying to reverse engineer the language through banging on the keyboard experimentation - or you can learn by doing the tutorials and following a good "How to learn C#" book. There are so many great "How do I build my first application" tutorials on the web... There are dozens of "Learn C# in 21 days", "My first C# program" type books at your local book seller or even public library.

I'll tell you from experience that just fumbling around in the dark and trying to teach yourself with no guidance doesn't work. Its like stumbling across a Harrier Jump Jet and trying to teach yourself how to fly with no background in piloting: You simply lack any groundwork to start from. How can you lay out your own training course if you don't already know the material? Would you go to a university where the teacher says "I don't know any of this but we'll fumble through it together?"

You need to start there. I can't say "I have little experience in speaking Russian, but I have been assigned to write a mystery novel in Russian. Can you help me?"

We can help you by saying "First learn basic programming and the language of C#. Then take on assignments." Could someone here write this program for you? Sure. Could someone here map out all the processes you need to follow and do the Software Design part of this in the slim hope you could code it from there? Sure. But we don't volunteer to do the job that you're either getting paid for, or getting a grade for. You may want to read this.

For now, just work on the lessons. Do a self-teaching book from cover to cover. Then consider writing a program.

Don't try to create a useful working program to fit a need of yours (or a for-pay contract) as your introduction to coding project. When you are learning to code you don't know enough to code a program, let alone know how to engineer the architecture of a program. It would be like saying "I don't know how to read sheet music, or play an instrument. I think I'll write a 3 act opera as my first learning experience."

I don't say this to be mean. We've seen lots of new coders take this approach and we know it doesn't work. Trying to design your own programs before you understand the basics of the code language you've chosen just leads to problems, frustrations, and 'swiss-cheese' education (lots of holes).

Everyone:

• Microsoft Visual Studio Tips, 251 ways to improve your productivity, Microsoft press, ISBN 0-7356-2640-5 Has many, many great, real-world tips that I use all the time.
  
• MSDN C# Developers Center with tutorials
  
• Welcome to Visual Studio
  
• Free editions of Visual Studio 2010
  
• Student editions of Visual Studio

Some of my common tips (some may apply more than others to your specific style):

• Take the extra 3 seconds to rename your controls each time you drag them onto a form. The default names of button1, button2... button54 aren't very helpful. If you rename them right away to something like btnOk, btnCancel, btnSend etc. it helps tremendously when you make the methods for them because they are named after the button by the designer.btnSend_Click(object sender, eventargs e) is a lot easier to maintain than button1_click(object sender, eventargs e)
  
  
• You aren't paying for variable names by the byte. So instead of variables names of a, b, c go ahead and use meaningful names like [font="Courier New"]index, timeOut, row, column and so on. You should avoid 'T' for the timer. Amongst other things 'T' is commonly used throughout C# for Type and this will lead to problems. There are naming guidelines you should follow so your code confirms to industry standards. It makes life much easier on everyone around you, including those of us here to help. If you start using the standards from the beginning you don't have to retrain yourself later.
  You might want to look at some of the naming guidelines. Its a lot easier to start with good habits than to break bad habits later and re-learn.
  
  
  • Guidelines for names
    
  • Naming guidelines
    
  • Design guidelines for classes
  
  
  
• Don't use your GUI objects as your variable. In other words don't keep referencing TextBox4.Text everyplace. TextBox4.Text is not a variable or property. The GUI is on its own thread so as soon as you start doing multi-threading you're screwed because your worker thread can't access the GUI elements. Use properties.
  
  
• Try to avoid having work actually take place in GUI control event handlers. It is better to have the GUI handler call other methods so those methods can be reused and make the code more readable. This is also how you can send parameters rather than use excessive global variables. Get in this habit even if you are using WinForms because WPF works a lot under the idea of "commands" and this will get you working towards that. Think of each gester, control click, menu option etc. as a command to do something such as a command to SAVE. It doesn't matter where the command comes from, all sources should point at the same target to do the actual saving.
  
  Spoiler

  
  

  // All of this different triggering mechinisms call the same single [il]SavePreferences()[/il] method
  
  btnSave(object sender, eventargs e)
  {
      SavePreferences(preferencesPath);
  }
  
  <KeyboardShortcut control+s bound to save>
  <Touchscreen guesture swiping from lowerleft to upperright bound to save>
  
  SaveMenuItem(object sender, eventargs e)
  {
      SavePreferences(@"C:\prefs\test.txt");
  }
  
  SaveContextMenu(object sender, eventargs e)
  {
      SavePreferences();// No parameter method overload
  }
  
  FormMain_Closing(object sender, eventargs e)
  {
      if (IsDirty) SavePreferences();
  }
  

  
  
  
• Don't replace lines of code that don't work. Instead comment them out and put your new attempts below that. This will keep you from re-trying the same ideas over and over. Also, when you come back to us saying "I've tried this 100 different ways and still can't get it", we can actually see what you tried. So often a failed attempt is very very close and just needs a little nudge in the right direction. So if we can say "See what you did in attempt 3... blah blah" it helps a lot

• You have to program as if everything breaks, nothing works, the cyberworld is not perfect, the attached hardware is flakey, the network is slow and unreliable, the harddrive is about to fail, every method will return an error and every user will do their best to break your software. Confirm everything. Range check every value. Make no assumptions or presumptions.
  
  
• I strongly suggest installing VMware or some other virtualization technology on your development PC so you can create a couple virtual computers for testing. This would allow you to debug and test inside: WinXP32, XP64, Vista, Win7x32, Win7x64... etc. without having to actually have 5 physical PC's. Visual Studio will let you send the debug directly into one of these virtual machines so you can watch it operate, check its variables, see the crashes and so on just as if it were debugging on your real machine.
  
  
• This can't be stressed enough in today's world of cell phone messaging:
  Don't use txt/sms/leet/T9 speak like: dnt no wut i m do-n, coz, al gud, b4, ny1, sum1, u r, and so on like this guy. Its completely disrespectful to the senior coding professionals that volunteer here to mentor you.
  
  
  Spoiler

  dis not b d'hood dawg... You are sitting at a real keyboard with a real monitor, not a cell phone. You are not here texting your high school posse to come to your kegger after their shift at Taco Bell. You are here asking for help from senior coding professionals who graciously donate their valuable time to helping the next generation of coders with their chosen craft. Please try to show them, yourself and the industry some respect by writing at least at an eighth grade level. (IE: English not ebonics or SMS, real words, punctuation and so on). If you can't take your own problem/question seriously enough to write like an adult, then why would you expect anyone else to take it seriously?
  
  When you write a post you are presenting yourself. Your writing style is all you have to show others who you are and what you stand for. When I see posts filled with lack of capitalization, SMS text like 'Urself', lack of punctuation and so on; what I see is someone who just doesn't care to make even an eighth grade presentation of themselves. I also see that you feel we are not worth the effort. Posts that look like this show that you don't feel the person you are talking to is worth speaking to as an adult. If you show this level of contempt or apathy towards someone you are asking for help how can you expect to be taken seriously or expect to receive that expert's fullest attention and time to help you?

[Skydiver]

Ouch! If you can't even read a string and get its characters, how do you expect to even write code to implement the Huffman encoding and decoding?

[tlhIn`toq]

To be fair the OP did say 'eventually'. Its good to have goals.
The problem here is the OP is trying to drive on the freeway as his first time behind the wheel.

Trust us when we tell you to just learn and do the exercises in the books for now. Designing a program comes later.

Hahah ok i will take you're advise. Can recommomend any book in particular for learning programming in C#?

  Don't use txt/sms/leet/T9 speak like: dnt no wut i m do-n, coz, al gud, b4, ny1, sum1, u r, and so on like this guy. Its completely disrespectful to the senior coding professionals that volunteer here to mentor you.
  
  
  Spoiler

  dis not b d'hood dawg... You are sitting at a real keyboard with a real monitor, not a cell phone. You are not here texting your high school posse to come to your kegger after their shift at Taco Bell. You are here asking for help from senior coding professionals who graciously donate their valuable time to helping the next generation of coders with their chosen craft. Please try to show them, yourself and the industry some respect by writing at least at an eighth grade level. (IE: English not ebonics or SMS, real words, punctuation and so on). If you can't take your own problem/question seriously enough to write like an adult, then why would you expect anyone else to take it seriously?
  
  When you write a post you are presenting yourself. Your writing style is all you have to show others who you are and what you stand for. When I see posts filled with lack of capitalization, SMS text like 'Urself', lack of punctuation and so on; what I see is someone who just doesn't care to make even an eighth grade presentation of themselves. I also see that you feel we are not worth the effort. Posts that look like this show that you don't feel the person you are talking to is worth speaking to as an adult. If you show this level of contempt or apathy towards someone you are asking for help how can you expect to be taken seriously or expect to receive that expert's fullest attention and time to help you?

Hi,

I just must need to solve this little problem i've got here.

I got this code

        private void btn_Click(object sender, EventArgs e)
        {
            byte[] data = File.ReadAllBytes("a.txt");

            int[] totals = new int[256];

            foreach (char b in data)
            {
                ++totals[b];
            }
        }

It gives me this:

But how can i show the frequency(occurrence) of each character in a.txt also?

You're on the right track.

You'll have to loop through the array and count. No magic call that does the work for you.

So when you have a value of 97, increase the value in your array at the 97th index.

Give it a try and if it doesn't work, show us your updated code.
