Learning C sharp

what are you talking about? everyone uses .rar files...

And also, i have my program exactly how i want it. I have a cs file for each window(form), one cs for the main method and one for events. Thats how i like it, as it makes it easier for me to find what i need.
And my program's structure does not have anything to do with my problem, i just found out :)
Because i made a whole new program (a little one) to test this. It contains a main cs file, and a content cs file. It is a window with a text box and a button in it. The button saves the content of the text box in a txt file in "C:/" and runs it in IE. I wrote in the text box: "My name it Tomas, and i live in Norway"

what i got in IE was: "System.Windows.Forms.RichTextBox, Text: My name is Tomas..."

Which i do not understand at all! i see no reason for it to do so, i gave it no reason to do so and its pretty annoying that a bunch of experts like yourself don't know why it does so :(

I don't. A zip file would be oh so much easier for me. If you repost with a zip, i could take a look.

Noone was saying that you're program doesn't work because you're using partial classes so much, what they were saying (and i agree) is that splitting your classes up so much just does not make sense. It makes it much harder to figure out what's going on in a particular class as you now have to hunt through several .cs files to find out where everything is declared. This makes bug hunting quite a lot harder.

If you ever get to the stage of working on applications consisting of a few dozen (or more) classes, you'll soon appreciate why your layout isn't so good.

What is the exact bit of code that's getting the text from the textbox?

OK if you realy want to stay out of any standard then do whatever you want, but then you have to accept that we are not looking for working extra hours to help people keeping their strange ideas about programming. And I can tell you this way you never will get an expert in this. And with that arrogant way you will no easily get a job in that business.

Actually, look up the Model-View-Controller design pattern. I think that's more what you're looking for. It is a particular way of splitting your code up in a clean, easy to understand manner.

Actually fewer than 5% of the computers (running Windows) I see have the ability to access an .rar file. But since a "compressed folder" is really a Zip file, EVERY windows computer can directly access a .zip file. [I have 37 computers here, 2 have WinRar].

Then feel free to use it. But don't ask/expect help with it.

I did not see a project with just those two files, but I will go back and look... (Went back and looked. Did not see a zip file posted which contained 2 .cs files (which is still not minimal, btw)).

This is the type of attitude that gets people ignored (or banned for life). We are all volunteers, we all have jobs, families, lives. And you think you have "some right" to get help??? You are not paying for this (I can send you a list of paid support sides strarting at $125/hr if you like).

That would probably be good for the OP's design, but is relly a divergence from the thread. What we (Jonny and myself) have been asking for is a MINIMAL program which duplicates the behavior. If it really is an issue with the RichText control, then the repro should (probably) be a total of 5-7 lines of code.....

You are so great my dear ! :D :D
Why should we have unnecessary hours of seeking, only why you are annoying regulations which, if used keeps standards in, which means, can be read more easily by any other programmer. So what you think that you feel good to oder it in your specific manner goes contrary to any other long proofed programming style. The question is do you want to learn or not. If not then why are you still here asking for your damned totally worse code.
type in an X in your gray textwindow ( richtextbox ) and it will instantly terminate your program.

Code:

---

//NEW FILEif (kea.KeyCode == Keys.F2 || kea.KeyCode == Keys.N && kea.Modifiers == Keys.Control)
{
txtbox1.Text = "";
}
//
//
//CLOSE
if (kea.KeyCode == Keys.X || kea.KeyCode == Keys.N && kea.Modifiers == Keys.Control)
{
Close();
}

---

This is the why. But looking for it normally needs some seconds. In your case I first have to research your strange ideas of splitting code of a Form in different pages. Its just as a puzzle :rolleyes:
The problemis obviously

Code:

---

//NEW FILEif ((kea.KeyCode == Keys.F2 || kea.KeyCode == )Keys.N && kea.Modifiers == Keys.Control)
{
txtbox1.Text = "";
}
//
//
//CLOSE
if ((kea.KeyCode == Keys.X || kea.KeyCode == Keys.N ) && kea.Modifiers == Keys.Control)
{
Close();
}

---

Because you havn't set the red braces your program uses or statement and as it is fulfilled pressing X it doesn't check further on and terminates the Mainwindow You yourself stetted the close command.
CPU_Wiz asked you in an early post if you havn't used the richtextbox with its ToString() Property. You answered 'no'
But in your code I found

Code:

---

void run_click(object sender, EventArgs run_click)
{
string tempFile = Path.GetFullPath("C:/csc/");
string file = tempFile + "temp" + ".html";
StreamWriter SW = File.CreateText(file);
//SW.Write(txtbox1);  // Here you have it You are not writing the text  to the stream you are using txtbox1 object as a string so the compiler did for you txtbox1.ToString()
// correct code would be
SW.Write(txtbox1.Text); 
SW.Close(); // I added this for you, but doing the code with using statement would be much better as mentioned before too
// Additional: You need to close the stream so your file is updated
// otherwise you cannot find any data on your webbrowser.
Form test = new Form();
test.Text = "Testrun";
test.Width = 640;
test.Height = 480;
WebBrowser wb = new WebBrowser();
wb.Parent = test;
wb.Dock = DockStyle.Fill;
wb.Url = new Uri(file);
test.Show();
 
}

---

Obviously you did the same error in your 'small testprogram' too, or you wouldn't have got the same fault.

I have also read the text of your about window.

Code:

---

lbl2.Text = "My name is Tomas Sandven.\nI have been programming since 20/3 2007, when i found my first free C# programming book on the internett. Since then i have been developing a series of programms to help me learn.\nMy official IM and email adress is [email protected]\nFeel free to contact me if you need any kind of help programming C#.";

---

Excuse me, but do you yourself really beliefe that you are in a state to help any other person in learning C# ? Come down to the earth please.:thumbd:

Here is the evidenz that I reapaired it ! But if you dont come down to the earth and correcting what we are trying to learn you. I'll disconnect of posts with your name

So, (after Jonny "gave it away"). Here is the offending line:

Code:

---

SW.Write(txtbox1);

---

This line of code calls the .ToString() method as I stated back in reply #91 (and i believe earlier, also)

However I discounted this because the Dahwan, specifically stated the problems was related to the contents of richtxtbox1

Simply amazing (even after all these years), how people can post completely incorrect information, and when asked to at least some some reasonable effort, become extremely rude.

Alas, it looks like I will be adding another person to the "Ignore" list (3rd one this year, out of 2000+ posts to people who showed at least some willingness)....

I think I'll follow this idea, because what me drives crazy is, that since post#85 he grumbles around that nobody finds his troubles. But in this post#85 he has shown a code which wasn't the code he really used in his program ! This code is nowhere ! So nobody could find this error. As I had seen the code of his testRumWindow class here on the web I was searching through his code where he will have something like richtextbox1 in his code, but I even could not find the testRunWindow code which he showed here.
Also nowhere in the program there was only a single line about a richtextbox1 in this code.
His code shown on the web was ( look at post#85)

Code:

---

using System;
using System.IO;
using System.Xml;
using System.Drawing;
using System.Threading;
using System.Collections;
using System.Diagnostics;
using System.Windows.Forms;
using WebSlinger.Properties;
using System.Text.RegularExpressions;
 
namespace editor
{
        class testRunWindow : Form
        {
                private WebBrowser browserWindow;
 
                public testRunWindow()
                {
                        //
                        //
                        //TestRun window
                        this.Text = "Options";        //titlebar text
                        this.Width /= 2;                        //width
                        this.Height /= 2;                //height
                        //
                        //
                        //Browser window
                        browserWindow = new WebBrowser();       
                        browserWindow.Dock = DockStyle.Fill;        //dock
                        browserWindow.Parent = this;                        //parent
                        browserWindow.Url = new Uri("http://www.google.com"); //adress
                }
        }
}

how do i get rid of the "System.Windows.Forms.RichTextBox, Text:" ?

So everyone looks for richtextbox1 through all of the program, which is perfect out of any standard, really never seen a better example of getting a private system of disorder, or should I say: mess ?
In the truth the 'run' button was a TestRun button, which had a run_click delegate, but thats nearly the same isn't it ? :rolleyes:
And who cares about that the richtextbox1 he mentioned here, in reality was named txtbox1 in the program and exactly that code which produced the error he didn't post. He said that he saved richtxbox1.Text ( see above ) Useless to say that in truth exactly in the not shown codepart he saved the datastream but using only textbox1 ( without .Text) as his source, which created the error, he was grumbling for all the time.

But blaming us for our helpfu hands, we are not able to repair his problems. Stubborn he refused all of our comments to get a standard order in his coding. Ignoring the fact that his confusing way also confused himself he declared that it could not be his code as he has done another project which created the same problem. reading his post about this I really think, he was believing he has found 'a big MS bug' :D :D

As I personally hate ignorance and as he is obviously a person who didn't really want to learn, whatfor should I any longer answer his posts ? :eek:
No, I for the future dont !

ignorance = lack of knowledge. This is expected, and why people post. ;)

arrogance is a problem.... :mad:

Oh thats definitly not, what I wanted to express. In german 'ignoring' things means not to give any attention to it. So for example when I say I will ignore his post it means, I will no longer read them, even if they show up on my PC. Whatever an other person says, if you are an 'Ignorant' you do in a way as if the other just hasn't said anything. 'Ignoring a person' means he is there, but you are doing like if he isn't there. If he is talking to you this is just the same, as he's talking against a stone ! In this way, I was talking about 'Ignorance' This comes from an attitude not to allow other people to be corrected by them. And is maybe in the deapest background a problem of a inferiority complex. This attitude is followed by an unability to learn then, because the person thinks - he himself knows all- .

Thats what was in my german pictures in my mind when I said 'I hate ignorance' But I can agree with you, that 'arrogance' is maybe the better word for this attitude :thumb:

This thread has been most amusing. At any rate, I am in the same boat as dahwin. I am trying to learn C#, a very daunting task I might say. I was wondering if you guys knew of any good, basic beginner books?

I do not have any programming experience in any language. I have been a system administrator for many years and would like to learn something knew. I just started with two step by step books(one is a for dummies book). One I had to put down as it is written for visual studio(older version) and I am unable to follow the steps in their walk through tutorial. I have done as much as I could out of that book. I am now using another book which seems to be pretty good but looking for more. My goal is to read the chapters of different books on the same topics at the same time to get a better understanding.

Any recommendations?

Yes and no. If you are trying to help people and they refuse to learn its sometimes absolutly frustrating. If someone takes your ideas just as a sponge takes water then its great to help people

The MS Visual Studio C# 2005 step by step is a good one.
also there is a pretty good book on the net which has many additional explantions and pictures to illustrate the concepts Its named Illustrated C#2005 and you find it here
http://www.apress.com/category.html?nID=38 in the C#section. Its only some few U$ to buy a download version. And there is additional a big file with examples

Basically what you need to learn is not a lot of books. Sure sometimes one book explaains something better then another one. But in my experience (and I'm now 40 years of school and I learned programming in a time where we used punched cards for programs, so I had to add a lot of knowledge in all the years for my own and I did this mostly by books ) if you read a book and you did not understand whats written there then you get tired to read furter on and took the next book. But thats wrong. Find out which words you cannot understand and you will be able to get fully understanding. Everytime if your head feels heavy take a PC and do examples for yourself, about things you have read and understood. Try it out and you get trained that way more and more.
then read next chapter, clear all terms in it and when understood do some examples.

You cannot read furteher on in a book when there stood OOP and you have no ides about what that means. And its also not enough that you know that this means Object Orientated Programming, you need to get fully understanding what this means so clarify what this is. Therefor you maybe need a good glossary or a simple book which minimum explains basichs of OOP . Then you can go further on in text and your knowledge will increase very fast. No matter it need half a weeek to clarify what OOP is, but after this, you are able to understand what this means and when this tech is used in the book you will make it out and understand whats going on. ( And modern programming is OOP technique all the time I would say)

So get the newer version MS Visual Studio C# 2005 Step by step

Its significant that when you have studied your materials very ycorrect then you have a very clear feeling in your head and your body feels lightweight. To less practicals and you will feel heavy of weight especially in the head. there is one additional part. I'm normally trying to visualize also theoretical concepts like data are a piece of paper and storing them means to put them in a square place on my table which then in my phantasy is my discdrive. Also I use drawings on paper, because visualisation is very good for understanding.
On the other hand, if you have misunderstoods or not understood words your head feels confused and dizzy.

So thats my experience and this way I have learned Basic of the 80th, Fortran, old C ( before we had any windows, PowerBasic, Basic for an old non IBM system, Access Basic in different versions , Borlands C++ , MS Visual Studio C++ with MFC , VB 4-6 and now I'm just learning C# since approximatly 3 quaters of a year now.

In nearly every of that languages I have coded programs. Training and studying gives you a fast progress. There is one additional part.
In my sight of view I can help others to the point of my own knowledge, no more, but helping others also is a good method to find leaks in my own knowledge. And its also training.
And i never have had the idea 'that I know all about siomething' Because this is the stonewall where all learning would be finished. thinking to know all about stops the possibility to learn about something. Got it ?

So feel free to ask whatever you need but IMHO never only ask for asking, without any practical usage in your mind. This sort of questions may be good in a philosophical aerea, but not in a practical study.
You are welcome:wave:

I have to agree with Jonny (been doing alot of that lately).

Pick ONE book. Start from the fronty and skip nothing. Key in EVERY code sample. Run EVERY code sample through the debugger, line by line. Move to the next paragraph/sample/chapter when you are convinced you have a solid understanding.

Use other sources (searching CodeGuru as well as Google) for clarification or additional information on things you find difficult.

If you run into some serious trouble, post here. Read the FAQ's before you post, and try to make sure your posts are complete will ALL the necessary information (We do have to charge $$$ for mindreading :lol: ).

Good Luck, and welcome to CG! :wave: :wave:
