i have created a form for a codeDOM compiler and it can compile my code if its in a single text file but i want to be able to compile the source code in the text file and a class thats in a text file so they can work together.
I am unsure how to code codeDOM to add my class file as a resource for the main source to be compiled
Heres what i have so far
codeDOM Compiler
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.CodeDom.Compiler;
using Microsoft.CSharp;
namespace CodeDOMSourceTest
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
}
private void btnCompile_Click(object sender, EventArgs e)
{
CompilerParameters Params = new CompilerParameters();
Params.GenerateExecutable = true;
Params.ReferencedAssemblies.Add("System.dll");
Params.ReferencedAssemblies.Add("TextFile1.txt");
Params.OutputAssembly = "output.exe";
string Source = Properties.Resources.CodeDOMSource;
Source = Source.Replace("[TEXT]", txtReplace.Text);
CompilerResults Results = new CSharpCodeProvider().CompileAssemblyFromSource(Params, Source);
if (Results.Errors.Count > 0)
{
foreach (CompilerError err in Results.Errors)
Console.WriteLine(err.ToString());
}
else Console.WriteLine("Compiled just fine!");
}
}
}
Source file
namespace testingCodeDOM
{
class Program
{
static void Main()
{
System.Console.WriteLine("[TEXT]");
Console.WriteLine(Testing.textwork());
System.Console.Read();
}
}
}
ClassFile
namespace testingCodeDOM
{
class Testing
{
public static string textwork()
{
string hello = "calss worked";
return hello;
}enter code here
}
}
Any ideas how to do this because i have googled it an am getting no were or at least nothing i understand
on a side not this works with with just the source but am trying to adapt it to use class files aswell
The CompileAssemblyFromSource() method can take any number of source code strings (since it's a params method). So, you can call it something like:
CompileAssemblyFromSource(Params, Source, ClassFile)
Where ClassFile is a string that contains the text of the second file.

(I am very new to C#) I am creating a forms application, and the purpose is to get a string from a Web API, then put that text onto a label. I have successfully gotten the data from the Web, but when I try to update the label, I have no luck.
I have debugged and found that my method inside my class Is executing, but just not setting the label's text. As you can see below, I tried to use this.resultLabel.text = str;. Here's the classes:
Program.cs (not the form cs file)
using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using System.Windows.Forms;
using System.Net.Http;
using System.Net;
using System.IO;
namespace WebsiteAPITest
{
static class Program
{
/// <summary>
/// The main entry point for the application.
/// </summary>
[STAThread]
static void Main()
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Application.Run(new Form1());
}
}
class PostManager
{
public void setupClient()
{
HttpWebRequest WebReq = (HttpWebRequest)WebRequest.Create(string.Format("https://yakovliam.com/phpApi/csTest.php"));
WebReq.Method = "GET";
HttpWebResponse WebResp = (HttpWebResponse)WebReq.GetResponse();
string respStr;
using (Stream stream = WebResp.GetResponseStream()) //modified from your code since the using statement disposes the stream automatically when done
{
StreamReader reader = new StreamReader(stream, System.Text.Encoding.UTF8);
respStr = reader.ReadToEnd();
}
MessageBox.Show(respStr);
Form1 form = new Form1();
form.SetResultLabel(respStr);
}
}
}
Actual form class (Form1.cs)
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
namespace WebsiteAPITest
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
}
private void GetButton_Click(object sender, EventArgs e)
{
PostManager postManager = new PostManager();
postManager.setupClient();
}
public void SetResultLabel(string str)
{
this.resultLabel.Text = str;
this.resultLabel.Refresh();
}
}
proof of label name:
Inside setupClient you call Form1 form = new Form1(); that creates a second Form1 which you never display, then you call SetResultLabel(respStr) inside this second form you never display, then you leave the method and discard it.
If you want to call SetResultLabel of your calling form, you have to pass the calling form to setupClient:
public void setupClient(Form1 callingForm)
{
...
callingForm.SetResultLabel(respStr);
Then inside your Form1:
postManager.setupClient(this);
It's quite dangerous to pass forms to other methods; a better design is to have the other method return data to your form:
public string setupClient()
{
...
return respStr;
}
And inside Form1:
SetResultLabel(postManager.setupClient());
Cannot enter text from class to textbox in form.
We set a keypress event in the MyTreeView class.
The text box cannot contain characters.
What should I do?
*set of textBox1.
*Change Modifiers for textBox1 properties from private to public
*Change keypress event from private to public
*(It didn't work well, so I keep it private now.)

If you want just to click an button and then print some text i don't understand why you are making another class.
Will be good to make your code efficient and not complicated.
In the main class
private void SendText_Click(object sender, EventArgs e)
{
textBox1.Text = "hi";
}
But if you want to make it complicated and make a class you shuld return i variable and send it to the other class the you can use it.
Learn how to use Public and private first and then use them.
You shuld have a public class which send data and the private to recive and process.
add (Exception ex) to your try catch.
so do:
try
{
// your code
}
catch (Exception ex)
{
MessageBox.Show(ex, "Error in (add where the error is)");
Console.WriteLine(ex);
}
So you will get a detailed Exception Message, maybe it helps you or maybe you will post it here, so we can see what the problem is.
And because you have System.Windows.Forms in your Using Directive
using System.Windows.Forms;
so
System.Windows.Forms.TreeNode[] tree1 = new System.Windows.Forms.TreeNode[2];
is redundant and can be shortened to:
TreeNode[] tree1 = new TreeNode[2];
I have a problem changing text from another class in another namespace. I have the first Form1 class :
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using System.Runtime.InteropServices;
namespace WindowsFormsApplication1
{
public partial class Form1 : Form
{
static Form1 mainForm;
[DllImport("kernel32.dll", SetLastError = true)]
[return: MarshalAs(UnmanagedType.Bool)]
static extern bool AllocConsole();
public static String LinkToApi = "http://google.com/api/";
public static Comunicator comunicator;
public static int debug = 5;
public Form1()
{
InitializeComponent();
AllocConsole(); // allow console
if(Form1.debug >= 3) Console.WriteLine("Application started");
comunicator = new Comunicator();
mainForm = this;
}
private void TestButton_Click(object sender, EventArgs e)
{
TestButton.Text = "Loading";
comunicator.TestConnection();
}
}
}
and this Comunicator class
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Net;
using System.Collections.Specialized;
using System.Windows.Forms;
using System.Runtime.InteropServices;
using System.IO;
using System.Threading;
namespace WindowsFormsApplication1
{
public class Comunicator
{
private String action = "idle";
public static Thread Start(Action action)
{
Thread thread = new Thread(() => { action(); });
thread.Start();
return thread;
}
public Comunicator()
{
}
public void TestConnection()
{
if (Form1.debug >= 3) Console.WriteLine("Testing connection");
// thread test
Start(new Action(ApiTest));
}
public void ApiTest()
{
if (Form1.debug >= 3) Console.WriteLine("API test begin");
// Create a request for the URL.
WebRequest request = WebRequest.Create("http://www.bogotobogo.com/index.php");
// If required by the server, set the credentials.
request.Credentials = CredentialCache.DefaultCredentials;
// Get the response.
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
// Display the status.
Console.WriteLine(response.StatusDescription);
// Get the stream containing content returned by the server.
Stream dataStream = response.GetResponseStream();
// Open the stream using a StreamReader for easy access.
StreamReader reader = new StreamReader(dataStream);
// Read the content.
string responseFromServer = reader.ReadToEnd();
// Display the content.
Console.WriteLine(responseFromServer);
// Cleanup the streams and the response.
reader.Close();
dataStream.Close();
response.Close();
// Console.Read();
if (Form1.debug >= 3) Console.WriteLine("API test end");
// Form1.StaticTestButton.Text = "Loaded"; <---- CHANGE HERE
}
}
}
which is not even a form class (I want to keep everything nice and clean). I want to change the TestButton text into "LOADED" but i get an error when I try to do that as if Form1.TestButton does not exist in Comunicator class.
I have tried to instantiate the class, I made a couple of variables static ... nothing, still getting error.
What is the problem? How may I solve this?
The request must be asynchronous, that's why I am using threads.
You should separate concerns, and you shouldn't communicate with UI in class which is not related to UI.
You should rewrite your code.
But as quick fix you should do the following.
In class Comunicator, you can do such field.
private readonly Action<string> _notifySimpleMessageAction;
Then add to Communicator constructor parameter notifyFunction. Code in constructor:
_notifySimpleMessageAction = notifyFunction
After that you should create Communicator in following manner:
communicator = new Communicator((notification)=>
{
StaticTestButton.BeginInvoke((MethodInvoker)(() => StaticTestButton.AppendText(notification)));
});
Then at the end of your method you should do
_notifySimpleMessageAction("Loaded")
Controller class:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
namespace ControllerDemonstrator
{
public class Controller
{
public event EventHandler CommunicatorDataLoaded;
public event EventHandler FormTestConnection;
private Form1 _form;
private Communicator _communicator;
public Form1 MainForm
{
get { return _form; }
}
public Controller()
{
_form = new Form1(this);
_form.TestConnection += _form_TestConnection;
_form.FormClosed += _form_FormClosed;
_communicator = new Communicator(this);
_communicator.DataLoaded += _communicator_DataLoaded;
}
public void Start()
{
_form.Show();
}
void _form_FormClosed(object sender, System.Windows.Forms.FormClosedEventArgs e)
{
// put any code to clean up the communicator resources (if needed) here
// --------------------------------------------------------------------
_communicator = null;
// Then exit
// ---------
Application.Exit();
}
private void _communicator_DataLoaded(object sender, EventArgs e)
{
if (null != CommunicatorDataLoaded)
{
CommunicatorDataLoaded(sender, e);
}
}
private void _form_TestConnection(object sender, EventArgs e)
{
if (null != FormTestConnection)
{
FormTestConnection(sender, e);
}
}
}
}
Basic form with one button (_testButton):
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
namespace ControllerDemonstrator
{
public partial class Form1 : Form
{
public event EventHandler TestConnection;
public Form1(Controller controller)
{
InitializeComponent();
controller.CommunicatorDataLoaded += controller_CommunicatorDataLoaded;
}
void controller_CommunicatorDataLoaded(object sender, EventArgs e)
{
_testButton.Text = "Loaded";
}
private void _testButton_Click(object sender, EventArgs e)
{
if (null != TestConnection)
{
TestConnection(this, new EventArgs());
}
}
}
}
Communicator class (everything has been stripped out, you will need to add in your logic):
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace ControllerDemonstrator
{
public class Communicator
{
public event EventHandler DataLoaded;
public Communicator(Controller controller)
{
controller.FormTestConnection += controller_FormTestConnection;
}
private void controller_FormTestConnection(object sender, EventArgs e)
{
// put your code that does the connection here
// -------------------------------------------
if (null != DataLoaded)
{
DataLoaded(this, new EventArgs());
}
}
}
}
And in your Program.cs (assuming that is how you are starting your application):
using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using System.Windows.Forms;
namespace ControllerDemonstrator
{
static class Program
{
/// <summary>
/// The main entry point for the application.
/// </summary>
[STAThread]
static void Main()
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Controller c = new Controller();
Application.Run(c.MainForm);
}
}
}
With this kind of design, the communicator doesn't know about the form and vice verse. You can expand it out to have different kind's of communicators/forms/etc and have the controller keep track of everything. It is also much easier to test code like this as you can test each separate piece on it's own since they don't depend on each other. This is a quick and dirty implementation. Do some research on the Model View Controller design pattern (not Microsoft MVC for asp.Net, but the actual design pattern). It is more code up-front to code an application with the MVC design pattern but it makes it easier to test and more maintainable.
How do I get a button click on a form to send the return of a called method to another class? Here is the pseudo code of what I have and any help would be greatly appreciated...

I want to get the return value from public string UseThis(string txt) into public string SendToOtherApp() which is visible to the other system that is calling this.
I am obviously new to C# so I am also very open to an overall critique of the project and best practices.
This is what I have done and it works great. In our ERP I run the codeunit, which calls the automation variable which is tied to the "OpenThis()" method. My form opens, I enter text in the textbox, click OK, it closes the from and the ERP pops a messagebox displaying the text from the message box. What do you C# experts think about this build? I am very interested in your thoughts on this solution so please let me know.

I am not sure if i got your goals right but here is the code that when called from a from, shows another modal form with a textbox, you enter a value into that textbox and close this modal form to find that value in that textbox returned to the first form that called for the show of the modal form.

Here in this example i am able create a folder(DMS) and sub-folder(SCOSTADL) and i want to create many sub-folders along with Sub-folder(SCOSTADL).please give me suggestions......
CreateDirectory creates all sub-directories in the path as well, so you can do Directory.CreateDirectory("C:\\abc\\def\\ghi");.
