I made a simple proxy checker but the problem is it is very slow. It takes much time because it checks one after one. I want to make it check +10 proxies in the same time. The question is: How can I make it fast using threads.
This is the simplified code :
namespace WindowsFormsApplication7
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
public void addgood() {
int co = int.Parse(bunifuCustomLabel1.Text);
co++;
bunifuCustomLabel1.Text = co.ToString();
}
public void testProxy(string ip, int port)
{
bool OK = false;
try
{
WebClient wc = new WebClient();
wc.Proxy = new WebProxy(ip, port);
wc.DownloadString("http://google.com/ncr");
OK = true;
addgood();
richTextBox2.Text +=ip+":"+port+"\n";
}
catch { }
}
private void bunifuFlatButton1_Click(object sender, EventArgs e)
{
openFileDialog1.Filter = "TXT Files | *.txt";
if (openFileDialog1.ShowDialog() == DialogResult.OK)
{
string fileName = openFileDialog1.FileName;
proxy_list.Text = File.ReadAllText(#fileName);
proxy_list.Refresh();
}
}
private void bunifuFlatButton4_Click(object sender, EventArgs e)
{
String ip;
int port;
if (proxy_list.Lines.Length < 1)
{
MessageBox.Show("Proxy list is Vide");
}
else {
foreach(String i in proxy_list.Lines){
String[] tab = i.Split(':');
port = int.Parse(tab[1]);
ip = tab[0];
testProxy(ip , port);
}
}
}
}
}
Here is an async implementation to your testProxy:
namespace WindowsFormsApplication7
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
public void addgood()
{
int co = int.Parse(bunifuCustomLabel1.Text);
co++;
bunifuCustomLabel1.Text = co.ToString();
}
public async Task testProxy(string ip, int port)
{
bool OK = false;
try
{
WebClient wc = new WebClient();
wc.Proxy = new WebProxy(ip, port);
await wc.DownloadStringTaskAsync(new Uri("http://google.com/ncr"));
OK = true;
addgood();
richTextBox2.Text += ip + ":" + port + "\n";
}
catch { }
}
private void bunifuFlatButton1_Click(object sender, EventArgs e)
{
openFileDialog1.Filter = "TXT Files | *.txt";
if (openFileDialog1.ShowDialog() == DialogResult.OK)
{
string fileName = openFileDialog1.FileName;
proxy_list.Text = File.ReadAllText(#fileName);
proxy_list.Refresh();
}
}
private void bunifuFlatButton4_Click(object sender, EventArgs e)
{
if (proxy_list.Lines.Length < 1)
{
MessageBox.Show("Proxy list is Vide");
}
else
{
var asyncTasks = new Task[proxy_list.Lines.Length];
for (int i = 0; i < proxy_list.Lines.Length; i++)
{
var tab = proxy_list.Lines[i].Split(':');
asyncTasks[i] = testProxy(tab[0], int.Parse(tab[1]));
}
Task.WaitAll(asyncTasks);
}
}
}
}

currently I am facing some difficulties in developing the code to log modbus data into XML format instead of CSV in c#. Following is the code which I have done:
public partial class FormMain : Form
{
public FormMain()
{
InitializeComponent();
InitializeRegisters();
}
private void FormMain_Load(object sender, EventArgs e)
{
try
{
//Start Modbus RTU Service
ModbusRTUProtocol.Start();
timer1.Enabled = true;

displayControl1.Register = ModbusRTUProtocol.Registers[0];

I am trying to read the coil and output the data read into xml logging file. However this is where I stuck on, can't get the it output the data into XML.
Can anyone please help me in this?
Try following :
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;
using System.Xml.Linq;
namespace ConsoleApplication189
{
class Program
{
const string FILENAME = #"C:\temp\test.xml";
static void Main(string[] args)
{
string xml = "<?xml version=\"1.0\" encoding=\"utf-8\"?><Modbus></Modbus>";
XDocument doc = XDocument.Parse(xml);
XElement modbus = doc.Root;
modbus.Add(new XElement("Register0", ModbusRTUProtocol.Registers[0]));
doc.Save(FILENAME);
}
}
}
I try to display crystal report in Report.aspx. so for this first i create class "``report_class` and in that class i create function like this:
using cookies
in webform2 i try this
public static bool setCookiesValue(Page page, string cookiesName, string cookiesValue, ref string ermsg)
{
if (cookiesValue.Trim().Length < 1)
{
ermsg = "cookies empty";
return false;
}
HttpCookie clearCookies = page.Request.Cookies[cookiesName];
clearCookies[cookiesName] = cookiesValue;
clearCookies.Expires = DateTime.Now.AddDays(1d);
page.Response.Cookies.Add(clearCookies);
return true;
}
public static String getCookies(Page page, string cookiesName)
{
try
{
HttpCookie GetCookies = page.Request.Cookies[cookiesName];
return GetCookies[cookiesName].ToString();
}
catch (Exception er)
{
return string.Empty;
}
}
then on button click
protected void Button6_Click(object sender, EventArgs e)
{
try
{
string datef = string.Empty;
setCookiesValue(this, "fromdate", "todate","regiondrop", ref ret);
report_class r = new report_class();
Report_Detail report = new Report_Detail();
Response.Redirect("Reports.aspx");
}
catch
{
Label4.Visible = true;
}
}
and in reports.aspx
protected void Page_Load(object sender, EventArgs e)
{
Report_Detail report = new Report_Detail();
report_class r = new report_class();
string date_f = getCookies(this, "fromdate");
string date_t = getCookies(this, "todate");
string drop_r = getCookies(this, "regiondrop");
r.Bindreport_class(report, Convert.ToDateTime(date_f),
Convert.ToDateTime(date_t), Convert.ToString(drop_r));
CrystalReportViewer1.ReportSource = report;
CrystalReportViewer1.DataBind();
}
but this show error
Error 8 No overload for method 'setCookiesValue' takes 5 arguments
Error 3 The name 'getCookies' does not exist in the current context
You just need to pass the value from for Example form1 to form2:
Do it this way:
FORM2
public partial class Form2 : Form
{
public static Label lblvar= null;
public Form2()
{
InitializeComponent();
}
private void Form2_Load(object sender, EventArgs e)
{
}
}
FORM1:
public partial class Form1 : Form
{
public Form1()
{
Form2.lblvar = lblvarinform1;
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
lblvarinform1.Text = txtdatepicker.Text;
Form2.lblvar.Text = lblvarinform1.Text;
}
}
USING COOKIES:
public static bool setCookiesValue(Page page, string cookiesName, string cookiesValue,ref string ermsg)
{
if (cookiesValue.Trim().Length < 1)
{
ermsg = "cookies empty";
return false;
}
HttpCookie clearCookies = page.Request.Cookies[cookiesName];
clearCookies[cookiesName] = cookiesValue;
clearCookies.Expires = DateTime.Now.AddDays(1d);
page.Response.Cookies.Add(clearCookies);
return true;
}
public static String getCookies(Page page,string cookiesName)
{
try
{
HttpCookie GetCookies = page.Request.Cookies[cookiesName];
return GetCookies[cookiesName].ToString();
}
catch (Exception er)
{
return string.Empty;
}
}
using the function above:
set cookies new value:
string ret = string.Empty;
setCookiesValue(this,"yourcookiesname","thisisyourdatevaue_or_any",ref ret);
get cookies value in another form:
string getval = getCookies(this,"yourcookiesname");
What I have to do is this:
Make an image gallery that has 5 buttons which each one select a folder of images.
Other two buttons for next and previous of the folder you are in. In my line 76, it says
argument 1: cannot convert from 'System.collection.Generic.list' to string
Any ideas?
Here's an image of the console
http://postimg.org/image/nct5pwdit/

pictureBox1.Load(semestres[semac].imagen[]);
I have the same command like 6 times.

So you have this:
pictureBox1.Load(semestres[semac].imagen);
Well the problem is that imagen is a List<string>. Picturebox.Load(string) takes a string, not a List<string>. So you need to get a string from that list instead of passing the whole list. One way would be:
pictureBox1.Load(semestres[semac].imagen[0]);
This would load the first image in that list.
Alternatively, you might be trying to do:
pictureBox1.Load(semestres[semac].imagen[cont]);
You just need to determine what the correct index is that you're trying to specify.
In Form1 I removed/deleted the _busy variable. In Form1 top I did:
BackgroundWebCrawling bgwc;
Then in the button4 pause click event I did:
private void button4_Click(object sender, EventArgs e)
{
bgwc.PauseWorker();
label6.Text = "Process Paused";
button5.Enabled = true;
button4.Enabled = false;
}
In the button5 click event button I did:
private void button5_Click(object sender, EventArgs e)
{
bgwc.ContinueWorker();
label6.Text = "Process Resumed";
button4.Enabled = true;
button5.Enabled = false;
}
And the cancel button click event:
private void button3_Click(object sender, EventArgs e)
{
bgwc.CancelWorker();
cancel = true;
}
Then I'm checking in Form1 completed event if cancel is true or not:
if (cancel == true)
{
label6.Text = "Process Cancelled";
}
else
{
label6.Text = "Process Completed";
}
And this is how the BackgroundWebCrawling class look like now:

}
public void ContinueWorker()
{

}
public void CancelWorker()
{
ContinueWorker();
mainBackGroundWorker.CancelAsync();
}
}
}
So I added the methods the pause the continue the cancel. In the dowork event, I changed all the things and added things.
But when I click the buttons there is no effect. Not pausing, not continue and not cancel. Nothing.
You never check the _busy status in mainBackGroundWorker_DoWork method;
for (int i = 0; i < WebSitesToCrawl.Count; i++)
{
_busy.WaitOne();
//...
}
also you should have your ManualResetEvent _busy in class with BackgroundWorker
ManualResetEvent _busy = new ManualResetEvent(true);
public BackgroundWorker mainBackGroundWorker;
public void PauseWorker()
{
if(mainBackGroundWorker.IsBusy)
{
_busy.Reset();
}
}
public void ContinueWorker()
{
_busy.Set();
}
and in Form1:
private void button4_Click(object sender, EventArgs e)
{
bgwc.PauseWorker();
//...
}
private void button5_Click(object sender, EventArgs e)
{
bgwc.ContinueWorker();
//...
}
to cancel the BackgroundWorker you can use CancellationPending property and CancelAsync method. Note: you should first unpause the worker.
public void CancelWorker()
{
ContinueWorker();
mainBackGroundWorker.CancelAsync();
}
private void mainBackGroundWorker_DoWork(object sender, DoWorkEventArgs e)
{
BackgroundWorker worker = sender as BackgroundWorker;
for (int i = 0; i < WebSitesToCrawl.Count; i++)
{
_busy.WaitOne();
if ((worker.CancellationPending == true))
{
e.Cancel = true;
break;
}
//...
}
}
If this doesn't help you, then you have problems with mainBackGroundWorker code and secondryBackGroundWorker.
This code only pauses mainBackGroundWorker, but not secondryBackGroundWorkers. The same with cancelation. If main worker is canceled? it will wait for all the secondary workers to finish their jobs. Also if you pause main worker? you can still have new results arriving from secondary workers.
You do not handle errors. If you have an exception in second worker, than you do not get any notification about that and also your main worker will never stop, because counter will never be 0.
There can be another problems, witch cause this behaviour.
I created a program that monitors what happens to the files inside a directory. For example if I add a new file, it shows the path and the name of the new file. Though I coded it in Windows Forms, I want to change it to a Console Application so that it shows the results on the console
My question is that how can I browse a folder using a console?
any ideas thanks in advance
The Windows Forms code is below:
private void button1_Click(object sender, EventArgs e)
{
DialogResult result = folderBrowserDialog1.ShowDialog();
if (result == DialogResult.OK)
{
button1.Enabled = false;
button2.Enabled = true;
directoryPath = folderBrowserDialog1.SelectedPath;
}
}
private void button2_Click(object sender, EventArgs e)
{
try
{
if (Directory.Exists(directoryPath))
{
textbox_append("monitor opened");
filesList = Directory.GetFiles(directoryPath);
timer1.Start();

First, you need to add reference to System.Windows.Forms
Second, add STAThread attribute to your method.
For example:
using System;
using System.Windows.Forms;
namespace ConsoleApplication1
{
class Program
{
[STAThread]
static void Main(string[] args)
{
OpenFileDialog ofd = new OpenFileDialog();
ofd.ShowDialog();
Console.Write(ofd.FileName);
}
}
}
