I have read the tutorial and can pass data from Form1 to Form2 but I am trying to find out if it is at all possible to be on Form2 and grab data that is on Form1.

What I am trying to do...

3 Forms
MainForm
ReportForm
BuildForm

MainForm
On the MainForm I have a menustrip with open and build. Below the menu strip is a panel. When a user clicks open in menustrip, it opens the ReportForm in the panel.

ReportForm
The ReportForm has a variable called theQuery. For now its default set to test. (Later will be changed based on a text file open.)

BuildForm
The BuildForm contains (for testing) a textbox called texboxQuery.

What I am wanting to happen is a user clicks open. The ReportForm loads all the variables it will store(with more stuff later). I want the user to be able to hit build in the menustrip of the MainForm. Then the BuildForm loads and fills out the textbox: textboxQuery with the data saved on the ReportForm variable theQuery.

So basically the ReportForm is just storing the variables and their data that BuildForm will need. The reason for this, is because I want the ability to open multiply reports. With each report possibly containing a different set of data.

So with how I am doing it.. Is there a way that the BuildForm can actually pull the variable data from the ReportForm? Or is the only way to do it, is create a button on the ReportForm that opens the BuildForm and passes the variables that way?

Ofcourse.
The easiest way is to pass the form1 to form2 while creating form2,than you can easy access to all data from form1.

Well this is my problem. I actually never open Form2 from Form1. In my example Form2 = BuildForm, Form1 = ReportForm, an then there is a MainForm. I open Form2 through the MainForm as Form1 is just a report form being opened in a Panel on the MainForm.

So I can not pass Form1 to Form2 as the button I am hitting is on the MainForm.

So it basically sounds like I am required to actually have to be on Form1, the form that stores the variables, and click a button on Form1 to send it to Form2?

I've been trying to hold myself back from posting on this thread but I can't stand it anymore. People forgive me if I sound like the crazy old man yelling "Get off my lawn!"

The prime issue is that MS completely failed the developer community with WinForms. WinForms development unfortunately steers programmers to mix view, model, and control code all into one form. This is why time again there is a question about how to pull data from another form. If you take time to at least just separate the model out of the form then you have a fighting chance.

So to wit, here is a basic outline:

class ProgramData {
    public ReportData ReportData;
    public BuildData BuildData;
}

class ReportData {
}

class BuildData {
}

class MainForm : Form {
    public MainForm(ProgramData programData) { ... }
}

class ReportForm : Form {
    public ReportForm(ReportData reportData) { ... }
}

class BuildForm : Form {
    public BuildForm(BuildData buildData, ReportData reportData) { ... }
}

In one of TlhIn'toq tutorials he shows how to keep the xxxData field up-to-date.

I hope this gives you a starting point.

no, you can be on any form a and access to any data(if its public) from any other form, you just need to send reference to that form.
take a look at this example: form1 is main form,form2 is "opened" from form1, form2 reads data from form1.
form1:

 public partial class Form1 : Form
    {
        public string DataToPass = "form1 data";

        public Form1()
        {
            InitializeComponent();
        }

        private void frm1_Load(object sender, EventArgs e)
        {
            Form2 frm = new Form2(this);
            frm.Show();
        }
    }

form2:

  public partial class Form2 : Form
    {
       private  Form1 FirstForm; 
        public Form2(Form1 f1)
        {
            InitializeComponent();
            FirstForm  = f1;
        }
        private void frm2_Load(object sender, EventArgs e)
        {
            MessageBox.Show(FirstForm.DataToPass);
        }
    }

And if you have 3 forms, and form1 is the main form,and form2 is "opened" from form1,and form3 is opened from form2, and you want to reach data in form3 from form1, you need to pass reference of the form1 through form2 to the form3.

Although that will work, it goes completely against the Law of Demeter. (Although the WikiPedia article is succint, this makes for much better reading: http://www.ccs.neu.e...boy/demeter.pdf )

ok, but this is the easiest way i think(for understanding). I'm not sure what Law Of Demeter is talking about, can you point out the irregularities in my example, or show the proper way of doing this by following the Law of Demeter?

    A condensed line like this makes a lot of assuptions that everything goes right, and gives you nothing to check or debug.
    
    If only for R&D / Debug purposes it can often be advantagous to break down the line
    
    

    if (dataset != null)
    {
       if (datase.Tables != null)
       {
          if (!string.IsNullOrWhiteSpace(tableName)
          {

  We see this a LOT, especially with rookies using textbox for numeric input.
  
  Any input that can't be converted to a number will do this.
  "5" can become 5
  "yogi" cannot become a number
  string.empty cannot become a number
  
  You would be best off changing from a textbox to a NumericUpDown or to inherit from textbox to make a numerictextbox.
  
  There are a LOT of articles on making a NumericTextBox. Try googling "C# NumericTextBox" and you should find a lot, such as this one on the MSDN:
  http://msdn.microsof...4(v=vs.80).aspx
  
  Once you study the code you'll see that as each key is pressed it is checked to see if it is a number. If not, then it is ignored. Thus the user can only enter numerically valid values.

  A: Make your new project a WinForms project. Then go back to project properties (Right-click on the project, select Properties).
  
  On the Application tab go to the dropdown that says "Windows Forms" and change it to "Console Application." You now have a WinForms application with a console window. I do this on occassion to see my Console.WriteLine statements when I am debugging. But don't consider this mixed mode operation a proper way to release an application for real-world use.

Quote

But when I kick off the background worker and it goes to change a label in this panel

I'll stop you right there. That underlying principal for your program is the problem and just won't work. The worker is a different thread than the one that created the GUI.

Background threads do not, ever, directly access anything that they didn't make. Period. Accept that and start re-designing.

Background worker raises events. You main class that makes this background worker has to subscribe to those events. Then that thread can update its GUI.

This is how is it meant to work. Each 'thing' in a program really should have only one purpose in life and cause no side affects. The background worker should do its job and nothing else. Its job is not to manage the GUI. The GUI thread's job is to manage the GUI.

Think of it this way: Your car dashboard has one job: To be the GUI for your car. But if the speedometer dies you don't want that to keep the engine from starting. The speedometer and the engine are 'loosely bound' for a reason. Your program is the same. You need the GUI to run whether or not the background worker does, and you want the background worker to run regardless which GUI you have on display.

So the background worker is kept ignorant of which panel you have up. It just says "I'm 50% done". If you have the simple panel or the complex panel on display doesn't matter. It hears the event and does whatever it is designed to do to display those results. Maybe the simple panel uses a progress bar, while the advanced panel display the exact percentage. The background thread doesn't know or care how it is shown.

Quote

So my main application should make a dozen threads to update the dozen similar controls?

To me that sounds like the main application is doing too much work and micromanaging the other controls. If the main application is coded for 12 background threads and panels, what happens in 6 months when you want to add a couple more panels? You have to update all your infrastructure to support them.

Personally I would make UserControls that consist of the Panel, its own backgroundworker and any pure objects that you might want to serialize for later restoration. The idea is to make a complete and fully self-contained 'Lego Block' of functionality. Then use your application to just hook them all together.

Now you can place 2 of your custom controls on screen... or 20... and they each take complete care of themselves. Only when one of your custom controls raises an event like LogThis(string message) or HighLevelWarning(int level) does the application have to do anything. The bulk of the work is done within the UserControl

In each of these UserControls I would create methods for Start() and Stop(). Let the UserControl handle its own needs.

Your main application should do nothing more than:

StartAllPanels()
{
   foreach(CustomPanel cp in myPanelsCollection)
   {
      cp.Start(); // Tell the panel to start
      cp.WarningMessage += WarningHandlerMethod; // Subscribe to warning event
      cp.LogThis += LogMessageHandlerMethod; // Subscribe to logging event
   }
}

See how your main application has no idea what the panel needs to do to start up? It doesn't try to micromanage the panel and tell it to start it's backgroundworker. The main app is blissfully ignorant of the inner needs of the component. Its like a the driver of a car. The driver doesn't tell the car: Close 12v power, start fuel pump, begin ignition computer, calibrate fuel/air mix, confirm foot is on brake, start ignition... The driver just turns the key to Start(). Your application should be the same. It only needs to know what it NEEDS to know. Let the rest of the parts take on as much responsibility as you can push on them.

Spending a little time on these tutorials before writing any more code should help you with a better understanding of all this and enable you to architect a better blueprint for your application. Work smarter not harder.

I've tried going through those, the only way im learning is through struggling to write code from scratch, the thought process i guess is helping me, i've tried reading sooo much and watching videos but honestly I'm not learning until I actaully type it.

I hear this a lot and the only thing I can think is students are buying the wrong books. Or they read the information and don't feel they need to actually work the lessons/exercises. This argument sounds like there are only two choices:

• Develop from scratch even though they haven't learned the language yet.
  
• Just read C# dictionaries.

Maybe this is from students buying the course textbook and reading it on their own, without the benefit of the teacher and their lesson plan and exercise assignments. When one mis-uses the materials, or only has 25% of the materials, of course they won't learn.

Here's a tip when selecting a book: If it is a dictionary of the language it is not a teaching book. Titles like "C# 4.0, The Complete Language" are not teaching books. If the title includes the words "Learn" or "Master" or "Teach" they might be teaching books. "Learn C# in 21 days", "Master C# in 2 hours a night", "Head First C#, A self-teaching guide" Then they are probably teaching books with a lesson plan and exercises to help you build up skills.

Obviously you didn't read the resources list I posted or get any one of the NUMEROUS self-teaching books.

Self-teaching books HAVE YOU TYPING CODE. They are NOT just reading as you describe.

C# is a language just like Russian or English. You cannot learn Italian by just reading an Italian dictionary.

Or even reading an English-to-Italian dictionary. You have to take lessons and do the learning exercises. Those lessons and exercises are developed by professionals to take place in a sequence proven to work, by taking the student from simple to complex concepts. You did not learn how to compose literary works in English by just reading a dictionary. You worked at lessons that taught you the syntactical use of verbs, nouns, additives and so on. You worked lessons that had you build simple things first like "Those are my apples. These are your pencils", and worked up from there.

So why are you trying to "just read" to learn C#? Or why are you insisting on trying to design and code a working program without first learning the language? It makes no sense! Its like saying you have to design and write a mystery novel as your introductory educational process to learn German. Its just a fraking ridiculous argument to try to take or defend.

There are numerous on-line learning series on the internet that have you learning and WRITING code, not just reading. We have them right here on DIC and they have been linked to you several times. There are many good guided self-teaching books, that once again are NOT just reading but teaching through proven methods of:

• Introduce new material
  
• Have student exercise with new material

Yet you insist that you don't need to go the route that has worked for the 3 generation of coders before you:

Representatives of which are here TELLING you that is the way to learn this science/skill/art.

would i be able to take out the private double[] months = new double[12];
and place it in a method instead of leaving it in a private field, why does it have to be in a private field as opposed to a method in just placing it in the main method?

Questions like this last one show just how badly you need to stop trying to write this program and just concentrate on learning the language through some sort of guided lesson plan. This question is filled with so much lack of understanding that it is hard to know where to start in an effort to answer it. To answer this someone would have to back up 5 chapters and help you get a grasp of certain introductory concepts. It's not right to ask that of people that have already devoted tens or hundreds of hours to develop the tutorials we have here. You shouldn't be asking them to repeat themselves because you feel you need special hand-holding or because you don't want to get the right books or because you don't want to actually work the exercises in the books or tutorials.

If you are struggling with how to do this you need to talk to your professor. Let him/her know you are struggling at this early stage in class. Make your professor do the job (s)he gets paid to do by either helping you or finding you a tutor or giving you more exercises from earlier in the book. You are paying for this education. Be an active part in not allowing the teacher to brush you off and let you slip through the cracks. If the other 50 people in class aren't struggling then don't blame the teacher. If the other 50 people are struggling then you all need to go to the professor's superior and tell him/her. If the prof is really incompetent then you don't need to help him keep his cushy 100,000/year job. If the prof isn't incompetent then you need to study harder or consider buying another book on programming. You aren't required to ONLY use the text book provided for the class.

A:

Spoiler

Your professor. That's where to start for a couple reasons:
1. They are getting paid to teach you. If they aren't teaching you this needs to come to their attention and that of their superiors.
2. You're the one paying them. Tens of thousands of dollars for your education. You need to learn to take every ounce of knowledge you can from these teachers and not sit passively back and try to learn it on the outside. If you were going to do that then you didn't need to take out all the student loans that are going to keep you in

debt for the next 15 years.
3. You need to let the teacher do their job. If you are struggling here you don't want to hide it. You need them to be aware of position so they can give you the time and attention you need. Otherwise you will be a little lost on chapter 1. A little more on 2. Way behind by chapter 3. You have to get a good foundation now if you are to gain anything in the later lessons.

Discussion topics:

Q: What is the best programming language/OS? What programming language/OS should I learn?
A:

Spoiler

All of them. And none of them. You might as well be asking "What is the best kind of vehicle?" Because the answer for both questions is "It depends on your needs and what personally suites you the best." C, C++, C#, Objective-C, Cocoa, F#, Visual Basic, Python, JAVA...

Are all good languages. They all have their pros and cons. They each have their strengths and weaknesses. Some have stronger footholds in some markets than others. Do you want to write for iPhone/iPad then you need Objective-C. Do you want to write for generic mobile phone use then you need JAVA. And so on. If you have no idea what area of programming you want to move to (Gaming, Financial, Windows, Macintosh, Cell phones) then nobody can advise you on a language. Personally, I would point you to C# because, like it or not, Microsoft owns the desktop computer market and C# will teach you good habits of design, OOP (Object Oriented Programming) design, inheritance and so on: Concepts that translate well to all other OOP languages.

The OS is a by-product of the type of coding you want to do, which in turn dictates the language you need, which then decides the operating system you probably need. Not the other way around.

Do you want to code apps for iOS devices like the iPad and iPhone? Then you need a Macintosh to do it right. Are you hankering to do machine vision programming? Industrial robot control? Financial applications?

What are your programming goals? Do you want to market $9.99 desktop applications to the masses? Do you want to make control systems for helicopters? XBox games requires the .NET XNA framework so you are now in Windows. Do you want to do embedded controls for automotive computers? Do you just love MS Office and love to make extensions for it? Do you want to work on web apps or desktop apps or mobile apps?

Do you now see why we can't even begin to tell you what is best for you? Only you know what you like and what you don't like. Only you know what area of programming is interesting to you. If you ask me for advice I might tell you video processing for the movie industry is great so you should get a Mac. Someone else is going to tell you cool stories of working on CSI lab equipment so you should do C embedded stuff.

The short answer for this question is: Get in touch with your own wants and needs then think for yourself.

You are asking a very vague, generalize question about a broad topic.
You might as well be asking... What is the best kind of vehicle to buy? Or what is the best kind of plastic to make? It all depends on your needs... Your area of business.

If you are interested in embedded devices like computers that control automobile engines it is still programming - but it is entirely different to writing a point of sale program meant to be used as a self-service kiosk like you see at Home Depot. And that is entirely different to writing a program that is meant to be used on a mobile platform.

You need to make a decision about what kind of programming, what area of interest, what industry you want to work in, before you can worry about the specifics of which language and OS and platform.

Q: Are there any resources for small C# projects a novice to become a better coder?
A:

Spoiler

There is a novice projects thread here on DIC. But here's my advice whenever this comes up:

Look around. Anyone who can't find a dozen projects a day by just walking through life, is doing so with their eyes closed to the world.

• Do you like the weather? What about a program to get the various weather reports from different web sites?
  
  Or to integrate with one of the numerous USB weather station hobby kits on the market?
  
• Do you like the run? What about a program to log your runs, routes and progress?
  
• Do you like movies? What about a program to catalog all your DVD's and AVI's?
  
• Do you like photography? What about a program to browse your images, assign tags and GPS?
  
• Do you like shooting? What about a program to track your aim and improvement?
  
• What about every time you walk into a business and someone says "Oh, I'm sorry. The computers are slow/suck.
  
  This is going to take 10 minutes and 25 screens." Sounds like an opportunity to make and maybe even sell them a new program. So go home and make it first before you open your mouth. If you succeed in something great. If you fail, then you know where to study more and you haven't embarrassed yourself.

If you succeed in something great. If you fail, then you know where to study more and you haven't embarrassed yourself.

Go to any of the on-line coder for hire sites. Read the new contract descriptions. DON'T BID ON THEM. Just read them. This will tell you what is requested by employers so you know where you have the potential to make money, and tell you where you should study. Then pick a project and build it. TRACK YOUR TIME. If you don't know how

long it takes you to build a project then you won't be able to bid on contracts. If you bid $50 for 50 hours of work you're going to starve to death. Again, building projects just to learn the technology and learn your own speed and weaknesses is something we all do/did and you need to do too. Once you can build a project just for the learning experience, fast enough that you could have made a competitive bid... Now you can start considering actually bidding on new contracts that are in your skill set.

Q: How do I sell the software I've developed?
A:http://www.dreaminco...m_notifications

Q: How do I decide how much to charge for my application?
A: Read this
A lot of questions about freelancing were covered in the Q&A with the Experts thread

Q: How do I deploy my program / Make an installer?
[b]A: C# application deployment project
Include the smallest .NET possible

Although that will work, it goes completely against the Law of Demeter.

ok, but this is the easiest way i think(for understanding). I'm not sure what Law Of Demeter is talking about, can you point out the irregularities in my example, or show the proper way of doing this by following the Law of Demeter?

A simplistic way to restate the "Law of Demeter" is "use only one dot". It is a design principle that encourages loose coupling of components. I highly recommend that you read the PDF I linked above because it is good reading and it will serve you well in the years to come.

So in your example with Form1, Form2, and Form3, you would be in this situation:

class Form1 {
    public string DataToPass = "Harry";
}

class Form2 {
    public Form1 FirstForm;
    public Form2(Form1 form1) {
        FirstForm = form1;
    }
}

class Form3 {
    public Form2 SecondForm;
    public Form3(Form2 form2) {
        SecondForm = form2;
    }

    void DoSomethingWithDataToPass() {
        SecondForm.FirstForm.DataToPass = "Voldemort";   //!!! We used more than one dot.
    }
}

This type of code establishes tight coupling between forms 1, 2, 3. Form3 needs to know that Form2 has a public Form1 reference. Form2 has to have a reference to Form1 even if it doesn't really need it, but just for the sake of Form3.

Or put another way is to quote from Meyers from "Effective C++": "Friends don't let friends play with their privates.". If you sit down and think about it, why does DataToPass, FirstForm, and SecondForm have to be public. They should really be private because they should only concern those classes. But now to effect the data passing you make the privates public (which is effectively what 'friend' does in C++).

I hope that all makes sense.
