I am a complete beginner in asp.net, C#, etc...
I saw this and this
Then I try this:
using System;
using System.Configuration;
using System.Data;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.IO;
using System.Text;
using System.Net;
using System.Collections.Generic;
using System.Xml;
using System.Collections;
using System.Collections.Specialized;
using System.Diagnostics;
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
Response.Write("Hello from code behind");
PerformanceCounter cpuload = new PerformanceCounter();
cpuload.CategoryName = "Processor";
cpuload.CounterName = "% Processor Time";
cpuload.InstanceName = "_Total";
//or PerformanceCounter cpuload = new PerformanceCounter("Processor", "% Processor Time", "_Total");
Console.WriteLine(cpuload.NextValue() + "%");
}
}
But that only displays Hello from code behind. Why please?
You're writing to the console, which won't work, write to the response instead (just as your string does):
Response.Write(cpuload.NextValue().ToString() + "%");
While applications types that aren't strictly console applications can have an associated console, they're not visible unless explicitly made so, and couldn't be in a web application.

I am trying to create a Configuration Tool for new devices, which has to be set up.
That's why I am trying to set the local hostname with a Button.
I want to use the name which I wrote in a textbox
public void SetMachineName(string newName)
{
// Create a new process
ProcessStartInfo process = new ProcessStartInfo();
// set name of process to "WMIC.exe"
process.FileName = "WMIC.exe";
// pass rename PC command as argument
process.Arguments = "computersystem where caption='" + System.Environment.MachineName + "' rename " + newName;
// Run the external process & wait for it to finish
using (Process proc = Process.Start(process))
{
proc.WaitForExit();
// print the status of command
Console.WriteLine("Exit code = " + proc.ExitCode);
}
}
public void Click_sethostname(object sender, RoutedEventArgs e)
{
SetMachineName(Textbox_sethostname.Text);
}
WPF setup
I have following namespaces:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;

I am currently developing a website by visual studio c# language and right now I am working on the user password reset page design. The problem I met is that I want to add the control to the textboxes and labels by using basic textbox.text = ""; method. But it keeps telling me it did not exist. I have searched a lot of solutions I am sure that:
1, It is the same name between the label name and the coding name.
2, There were no other same name pages since I was re-created another page with different names.
3, All these are added:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Net;
using System.Net.Mail;
using System.Drawing;
using System.Configuration;
using System.Data.SqlClient;
using System.Data;
using System.Text;
using System.IO;
Can anyone help? I confused here for a few days already:)
protected void SubmitButton_Click(object sender, EventArgs e)
{
string CS = ConfigurationManager.ConnectionStrings["DBCS"].ConnectionString;
using (SqlConnection con = new SqlConnection(CS))
{
SqlCommand cmd = new SqlCommand("spResetPassword", con);
cmd.CommandType = CommandType.StoredProcedure;
SqlParameter paramUsername = new SqlParameter("#UserName", userTextBox.text);
cmd.Parameters.Add(paramUsername);
con.Open();
SqlDataReader rdr = cmd.ExecuteReader();
while (rdr.Read())
{
if (Convert.ToBoolean(rdr["ReaturnCode"]))
{
SendPasswordResetEmail(rdr["Email"].ToString(), TextBox1.Text, rdr["UniqueId"].ToString());
msgLabel.Text = "An reset password Email has sent to your Email address.";
}
else
{
msgLabel.Text = "username not found!";
}
}
}
Does your textbox control have the following attribute?
runat="server"
I'm trying to create an application in C#.Net, and I need it to scan the processes that the user start and stop, but I'm getting an "Access Denied" on the .Start()
Here is what I've got so far
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Security.Cryptography;
using System.Text;
using System.Threading;
using System.Threading.Tasks;
using System.Windows.Forms;
using MySql.Data.MySqlClient;
using System.Management;
using Security;
using MySQLConnectivity;
namespace MyApp
{
public partial class Login : Form
{
MySQLClass sql = new MySQLClass();
ManagementEventWatcher processStartEvent = new ManagementEventWatcher("SELECT * FROM Win32_ProcessStartTrace");
ManagementEventWatcher processStopEvent = new ManagementEventWatcher("SELECT * FROM Win32_ProcessStopTrace");
public Login()
{
InitializeComponent();
processStartEvent.EventArrived += new EventArrivedEventHandler(processStartEvent_EventArrived);
processStartEvent.Start();
processStopEvent.EventArrived += new EventArrivedEventHandler(processStopEvent_EventArrived);
processStopEvent.Start();
}
void processStartEvent_EventArrived(object sender, EventArrivedEventArgs e)
{
string processName = e.NewEvent.Properties["ProcessName"].Value.ToString();
string processID = Convert.ToInt32(e.NewEvent.Properties["ProcessID"].Value).ToString();
MessageBox.Show("Process started. Name: " + processName + " | ID: " + processID);
}
void processStopEvent_EventArrived(object sender, EventArrivedEventArgs e)
{
string processName = e.NewEvent.Properties["ProcessName"].Value.ToString();
string processID = Convert.ToInt32(e.NewEvent.Properties["ProcessID"].Value).ToString();
MessageBox.Show("Process stopped. Name: " + processName + " | ID: " + processID);
}
}
}
I've searched online hours, but couldn't find anything. People that had this problem, had it remotelly, and not locally. I am using Windows Pro 8.1 + Microsoft Visual Studio Ultimate 2013, just in case that versions of VS or OS may be important in this case.
The problem triggers on processStartEvent.Start() saying "Access denied".
I also tried to switch from .Start() to .WaitForNextEvent() with the same result
Anything that I'm missing here?
ClickOnce was activated. Disabling it solved my problem. Thanks tho.
I have ran a debug stepping through the program and it crashes at the following line
Runspace runspace = RunspaceFactory.CreateRunspace();
It gives the following error
An unhandled exception of type 'System.InvalidProgramException' occurred in PrimarySMTP_Fix.exe
Additional information: Common Language Runtime detected an invalid program.
This is my first time working with Power Shell through C# and I'm having trouble getting some simple code execution. The point of the project is to automate a simple fix for a common issue with our company's exchange server.
The complete code is below.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;
using System.Management.Automation;
using System.Collections.ObjectModel;
using System.Management.Automation.Runspaces;
namespace PrimarySMTP_Fix
{
public partial class MainWindow : Window
{
//Variable Declarations
string userName = "";
string confirmUser = "";
string primarySMTP = "";
string confirmSMTP = "";
public MainWindow()
{
InitializeComponent();
}
private string RunScript(string scriptText)
{
Runspace runspace = RunspaceFactory.CreateRunspace();
runspace.Open();
Pipeline pipeline = runspace.CreatePipeline();
pipeline.Commands.AddScript(scriptText);
pipeline.Commands.Add("Out-String");
Collection<PSObject> results = pipeline.Invoke();
runspace.Close();
StringBuilder stringBuilder = new StringBuilder();
foreach (PSObject obj in results)
{
stringBuilder.AppendLine(obj.ToString());
}
return stringBuilder.ToString();
}
private void Button_Click(object sender, RoutedEventArgs e)
{
userName = adUser.Text;
confirmUser = confirmAD.Text;
primarySMTP = mail.Text;
confirmSMTP = confirmMail.Text;
outPut.Text = RunScript(userName);
}
}
}
The above is just setup to test. For now it's taking just the username information and running it directly as a command. If I can get that to work and output information then I can re-write it to do what I want it to do.
After playing around for a while I found that I needed to reinstall the Windows Management Framework to get it to work. Figured that out when I put the debug build on the server and ran the test there and it worked.
MailMessage is not working i don't know what I'm missing. Pls correct my program if there is missing codes or did i use wrong namespace?
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Net;
using System.Net.Mail;
using System.Web.Mail;
using System.Data.SqlClient;
using System.Data;
protected void btnsend_Click(object sender, EventArgs e)
{
try
{
SmtpClient smtp=new SmtpClient("smtp.gmail.com",587);
smtp.EnableSsl = true;
smtp.UseDefaultCredentials = false;
smtp.Credentials=new NetworkCredential(txtemail.Text,txtpassword.Text);
MailMessage mail = new MailMessage(txtemail.Text, ddlemail.Text, txtsubject.Text, txtbody.Text);
smtp.Send(mail);
}
catch (Exception ex)
{
Console.WriteLine("{0} Exception caught.", ex);
}
}
The problem is because you have referenced
using System.Net.Mail;
using System.Web.Mail;
So there was ambiguous reference between System.Web.Mail.MailMessage and System.Net.Mail.MailMessage
Remove using System.Web.Mail; reference
