I am trying to find code to make a calculator of sorts. I need it to be three input boxes where you can type data in the first two boxes. First box divided by the second box and the result is then multiplied by 9 (the nine not shown) and the result or answer is shown in the third text box. With some sort of compute or calculate button.
This should do it:
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 calculator
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
int answer = (Convert.ToInt32(txt1.Text) / Convert.ToInt32(txt2.Text)) * 9 ;
txtAnswer.Text = Convert.ToString(answer);
}
}
}

i am trying to make a screen viewer.
i have an C# server side that works good and i have C# client side that works good.
this is my C# client side code:
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.Net.Sockets;
using System.Net;
using System.Threading;
using System.Drawing.Imaging;
using System.Runtime.Serialization.Formatters.Binary;
namespace WindowsFormsApp24
{
public partial class Form1 : Form
{
private readonly TcpClient client = new TcpClient();
private NetworkStream mainStream;
private int portNumber;
private static Image GrabDesktop()
{
Rectangle bound = Screen.PrimaryScreen.Bounds;
Bitmap screenshot = new Bitmap(bound.Width, bound.Height, PixelFormat.Format32bppArgb);
Graphics graphics = Graphics.FromImage(screenshot);
graphics.CopyFromScreen(bound.X, bound.Y, 0, 0, bound.Size, CopyPixelOperation.SourceCopy);
return screenshot;
}
private void SendDesktopImage()
{
BinaryFormatter binFormatter = new BinaryFormatter();
mainStream = client.GetStream();
binFormatter.Serialize(mainStream, GrabDesktop());
}
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
portNumber = 443;
try
{
string ip = "192.168.1.55";
client.Connect(ip, portNumber);
}
catch
{
}
timer1.Start();
}
private void textBox1_TextChanged(object sender, EventArgs e)
{
}
private void btnConnect_Click(object sender, EventArgs e)
{
}
private void timer1_Tick(object sender, EventArgs e)
{
SendDesktopImage();
}
}
}
The thing i am trying to do, is to switch the client side from C# to powershell.
is that possible? i am searching for ideas on google for along time, I would be happy
to hear what you have to say.. many thanks.
C# and Powershell are both using some version of the Dot Net runtime so the same objects and properties should be available in both, just by a different syntax. The process for converting between the two is basically this:
First you need to load the required assemblies into powershell with Add-Type. You will require several assemblies such as System.Net, System.Drawing and System.Windows.Forms to get access to the Objects in your code. (this is essentially the same as adding references to a C# project). Example: Add-Type -AssemblyName System.Drawing; would load everything inside System.Drawing.dll
Next you need to convert the syntax from C# to powershell line by line:
Example
private readonly TcpClient client = new TcpClient();
Would become:
[System.Net.Sockets.TcpClient] $client = New-Object System.Net.Sockets.TcpClient
Mostly this process will be simplification and expanding names. Above [System.Net.Sockets.TcpClient] is the fully qualified type - ie the long form name of the C# Class (visible on the tooltips in Visual Studio). New-Object is equivalent to new
Assuming you just want the screenshot to be taken and sent each time the script is executed you dont need to worry about writing classes or functions in powershell you can just convert each functional line of c# into powershell in a text file saved with .ps1 extension.
using a button to load a scene and iam just getting the error "Assets\Scripts\button_press.cs(15,59): error CS1503: Argument 1: cannot convert from 'UnityEngine.Object' to 'string'"
code:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.SceneManagement;
public class button_press : MonoBehaviour
{
public Object sceneToLoad;
public void PlayGame ()
{
UnityEngine.SceneManagement.SceneManager.LoadScene(sceneToLoad);
}
public void QuitGame()
{
Debug.Log (" You have quit");
Application.Quit();
}
}
The LoadScene API expects either an integer referring to the scene number in the build, or a string referring to the name of the scene (generally preferred).
You should define your sceneToLoad field as a string rather than an Object.
I am making a 2D platformer where I want the users inputted name to hover over there character.
This is what the menu screen looks like
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
using UnityEngine.SceneManagement;
public class set_usernames : MonoBehaviour {
public InputField name;
public InputField second_name;
private string Bader_input_name;
private string Dwarf_input_name;
public void updatename(string name){
}
public void setget()
{
//Debug.Log (name.text);
Bader_input_name = name.text;
Dwarf_input_name = second_name.text;
//Application.loadedLevel("game");
Debug.Log ("name was " + Bader_input_name);
Debug.Log ("name was " + Dwarf_input_name);
SceneManager.LoadScene ("map_select");
}
}
This is the error message I get
Basically what that means is that you are trying to access an object that's not instantiated. I have no idea how are you trying to access the input but the easiest way is to make two public inputs in your UIController drag and drop them in Unity and access the Text property of input objects like so: myInput.Text.
I am new to MEF and I am trying this following program.
The class library whose dll I am making has following code:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.ComponentModel.Composition;
namespace MefTestsCore
{
[Export (typeof(MefTestsCore.IFace))]
public class CoreClass1 : IFace
{
public String getName()
{
return "CoreClass1";
}
}
interface IFace
{
String getName();
}
}
The program which wants to access the dll has following code :
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.ComponentModel.Composition;
using System.ComponentModel.Composition.Hosting;
using MefTestsCore;
namespace MefTests
{
class Program
{
[Import (typeof(MefTestsCore.IFace), AllowRecomposition=true)]
public IFace iFaceObj;
static void Main(string[] args)
{
Program p = new Program();
p.Method();
}
public void Method()
{
DirectoryCatalog catalog = new DirectoryCatalog(#"C:\Users\username");
CompositionContainer container = new CompositionContainer(catalog);
container.ComposeParts(this);
Console.WriteLine(iFaceObj.getName());
Console.ReadKey();
}
}
}
I have the MEFLibrary.dll (dll containing MefTestsCore namespace, the first part of above code) at C:\Users\username. When I run the program, it throws CompositionException with following details
The composition produced a single composition error.
The root cause is provided below. Review the CompositionException.Errors property for more detailed information.
1) The export 'MefTestsCore.CoreClass1 (ContractName="MefTestsCore.IFace")' is not assignable to type 'MefTestsCore.IFace'.
Resulting in: Cannot set import 'MefTests.Program.iFaceObj (ContractName="MefTestsCore.IFace")' on part 'MefTests.Program'.
Element: MefTests.Program.iFaceObj (ContractName="MefTestsCore.IFace") --> MefTests.Program
In your test program you are using MefTestsCore. So I assume you referenced that assembly from your test program. But then you also load a copy from c:\Users\username. Now they types don't match because they come from different assemblies.
You have to put the interface into it's own assembly so that you then can reference it from your program and from MefTestsCore.
Hi I am a student I am getting this error:

this.textBox1.Text = result;
}
private void button1_Click(object sender, EventArgs e)
{
listBox1.Items.Add(textBox2.Text);
textBox2.Clear();
}
}
}
Pl. help me
Your code works fine for me. However, your code will break if you've added something other than a string to your ListBox's Items collection (although this will produce a different error than what you're apparently seeing).
Can you add the code you use to populate this ListBox?
