I am trying to use SharpSSH to use the "view" command in the shell to read a file remotely. I am able to access and view it, but it only returns about 120 lines or so before the form locks up with no exception being thrown. Here is my code:
SshStream Shell = null;
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
string host = "10.100.100.15";
string user = "root";
string password = "pass";
Shell = new SshStream(host, user, password);
}
private void button1_Click(object sender, EventArgs e)
{
if (Shell != null)
{
try
{
Shell.Write("cd /var/log");
Shell.Write("view info.log");
StreamReader reader = new StreamReader(Shell);
string inputLine = Shell.ReadResponse();
while ((inputLine = reader.ReadLine()) != null)
{
lstLines.Items.Add(inputLine);
}
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
}
}
I am still learning to use this code, so I am just trying to display the lines that it returns in a listbox. There are about 2200 lines in the file, but it only returns about 100.
I've found a solution for my problem. Instead of using "view info.log", and am using "cat info.log". It shows all lines without prompting to continue. Thanks for your help!

Server 1 Server2 Server Config Screen
I am trying to make a video game server manager and I have run into an issue. I want the user to be able to have as many servers as they would like. However I cannot figure out through google searching and just regular messing around how to store the information that the user selects to become associated with the Server they create in the list. Basically when you make Server1 it takes the info you selected from the boxes on the config screen and uses them on the server selection page. But, when you make Server2, the configuration overwrites Server1's configuration. I know my code isn't even setup to be able to do this but I would appreciate a push in the right direction as to which type of code I should use.
Tl:dr I want config options to be associated with ServerX in the server list and each server should have unique settings.
public partial class Form1 : Form
{
//Variables
string srvName;
string mapSelect;
string difSelect;
public Form1()
{
InitializeComponent();
this.srvList.SelectedIndexChanged += new System.EventHandler(this.srvList_SelectedIndexChanged);
}
private void srvList_SelectedIndexChanged(object sender, EventArgs e)
{
if(srvList.SelectedIndex == -1)
{
dltButton.Visible = false;
}
else
{
dltButton.Visible = true;
}
//Text being displayed to the left of the server listbox
mapLabel1.Text = mapSelect;
difLabel1.Text = difSelect;
}
private void crtButton_Click(object sender, EventArgs e)
{
//Add srvName to srvList
srvName = namBox1.Text;
srvList.Items.Add(srvName);
//Selections
mapSelect = mapBox1.Text;
difSelect = difBox1.Text;
//Write to config file
string[] lines = { mapSelect, difSelect };
System.IO.File.WriteAllLines(#"C:\Users\mlynch\Desktop\Test\Test.txt", lines);
//Clear newPanel form
namBox1.Text = String.Empty;
mapBox1.SelectedIndex = -1;
difBox1.SelectedIndex = -1;
//Return to srvList
newPanel.Visible = false;
}
}
You mentioned in a recent comment that you had tried saving to a .txt file but it overwrote it anytime you tried to make an additional one. If you wanted to continue with your .txt approach, you could simply set a global integer variable and append it to each file you save.
//Variables
string srvName;
string mapSelect;
string difSelect;
int serverNumber = 0;
...
serverNumber++;
string filepath = Path.Combine(#"C:\Users\mlynch\Desktop\Test\Test", serverNumber.ToString(), ".txt");
System.IO.File.WriteAllLines(filepath, lines);
I think below source code will give you some idea about the direction. Let us start with some initializations:
public Form1()
{
InitializeComponent();
this.srvList.SelectedIndexChanged += new System.EventHandler(this.srvList_SelectedIndexChanged);
mapBox1.Items.Add("Germany");
mapBox1.Items.Add("Russia");
difBox1.Items.Add("Easy");
difBox1.Items.Add("Difficult");
}
This is the event handler of the "Create Server" button. It takes server parameters from the screen and writes to a file named as the server.
private void crtButton_Click(object sender, EventArgs e)
{
//Add srvName to srvList
srvName = namBox1.Text;
srvList.Items.Add(srvName);
//Selections
mapSelect = mapBox1.Text;
difSelect = difBox1.Text;
//Write to config file
string path = #"C:\Test\" + srvName + ".txt";
StreamWriter sw = new StreamWriter(path);
sw.WriteLine(mapSelect);
sw.WriteLine(difSelect);
sw.Flush();
sw.Close();
//Clear newPanel form
namBox1.Text = String.Empty;
mapBox1.SelectedIndex = -1;
difBox1.SelectedIndex = -1;
//Return to srvList
//newPanel.Visible = false;
}
And finally list box event handler is below. Method reads the server parameters from file and displays on the screen.
private void srvList_SelectedIndexChanged(object sender, EventArgs e)
{
if (srvList.SelectedIndex == -1)
{
dltButton.Visible = false;
}
else
{
dltButton.Visible = true;
}
string path = #"C:\Test\" + srvList.SelectedItem + ".txt";
StreamReader sr = new StreamReader(path);
//Text being displayed to the left of the server listbox
mapLabel1.Text = sr.ReadLine(); // mapSelect;
difLabel1.Text = sr.ReadLine(); // difSelect;
}
Please feel free to ask any questions you have.
I ended up figuring out the issue. Basically I ended up deciding on a write to a txt file and then read from it to display the contents of the file in the server select menu. I also added a delete button so you can delete the servers that you created. it does not have full functionality yet but it is there. So here it what I ended up with and it works perfectly. Thank you all for trying to help.

I am having a problem with a with a code that I used for my C# application. When I click on the browse button and select the file dialogue box opens twice.
private void txt_location_TextChanged(object sender, EventArgs e)
{
string folderPath = "";
FolderBrowserDialog folderBrowserDialog1 = new FolderBrowserDialog();
if (folderBrowserDialog1.ShowDialog() == DialogResult.OK) {
folderPath = folderBrowserDialog1.SelectedPath;
}
}
private void Button21_Click(object sender, EventArgs e)
{
using(var fbd = new FolderBrowserDialog()) {
DialogResult result = fbd.ShowDialog();
if (result == DialogResult.OK && !string.IsNullOrWhiteSpace(fbd.SelectedPath)) {
selectedPath = fbd.SelectedPath;
txt_location.Text = selectedPath;
}
}
}
private void bunifuThinButton21_Click_1(object sender, EventArgs e)
{
System.IO.StreamWriter file;
bool isvalid = ValidateInputs();
try {
file = new System.IO.StreamWriter(selectedPath + # "\dred.txt");
catch (Exception ex) {
MessageBox.Show("Please, Select valid Path..");
return;
}
try {
if (isvalid) {
WriteLines(file);
}
}
catch (Exception ex2) {
MessageBox.Show(ex2.Message);
}
finally {
file.Close();
}
}
}
Obviously, it is only meant to open once to enable me to read the selected file. This works, but only once I have selected the file twice.
Thanks in advance for your help.
You have FolderBrowserDialog being instantiated and shown on two different events:
txt_location_TextChanged
and
Button21_Click
You're having two popups because each one is firing once separately.
You should probably remove the event txt_location_TextChanged entirely unless you need it for another thing that isn't popping the FolderBrowserDialog again.
First off, I'm on a Win7 laptop using Chrome in my IE.
I can store the data I have with a session variable but cannot get it to work with a cookie.
I attempt to set the cookie in a button click event and then attempt to read it in a textChanged event. I can see the cookie object get populated in the IE but it never seems to actually get created when I look for it with chrome://settings/cookies.
Here is my code:
protected void btnSubmitQuery_Click(object sender, EventArgs e)
{
List<string> geometryList = new List<string>();
try
{
using (SqlConnection conn = new SqlConnection(this.SqlQri.ConnectionString))
{
conn.Open();
using (SqlCommand cmd = new SqlCommand(this.tbxSQLQri.Text, conn))
{
object result = cmd.ExecuteScalar();
Session["polys"] = result.ToString();
HttpCookie myPolys = new HttpCookie("polys"); // This seems to work
myPolys.Value = result.ToString();
myPolys.Expires = DateTime.Now.AddDays(1);
Response.SetCookie(myPolys);
}
conn.Close();
}
}
catch (SqlException ex)
{
this.tbxSQLQri.Text = "Query Exception";
}
}
protected void TextBox1_TextChanged(object sender, EventArgs e)
{
// Read Session val
string looky = (string)(Session["polys"]);
this.TextBox1.Text = looky;
string lookyHere = "";
if (HttpContext.Current.Request.Cookies["polys"] != null) // This is never true!
{
lookyHere = Request.Cookies["polys"].Value;
}
this.TextBox2.Text = lookyHere;
}
I declare a Private constant string with the name as follows
private const string cnstLoginCookieName = "Super-User";
inside of my Page_load I have the following declared
protected void Page_Load(object sender, EventArgs e)
{
HttpCookie objCookie = new HttpCookie(cnstLoginCookieName);
objCookie.Values["Login"] = username.Trim();
objCookie.Values["Company"] = "CoolFirm";
objCookie.Expires = DateTime.MaxValue;
Response.Cookies.Add(objCookie);
}
OK, This part of my problem was solved. My string was too long to go in a cookie.
POLYGON ((-122.143636 47.257808, -122.143685 47.257807, -122.143877 47.257802, -122.143993 47.257799, -122.143989 47.257746,
If I changed the value to "hello world" the cookie was successful.
Thank you for your help on this.
Having a lot of trouble with this. I'm working on a large project, so there's only a few classes I'm interested in and working on. Basically, these are forms - one is a main editor where a user edits details and the other is used to assign a pin number. In the main editor form, if the user has a pin, they can choose to edit this pin. Here's where my problem lies - if I edit the pin, what I'm doing in the code is deleting the old pin and adding the new one. However, the database doesn't update until AFTER the editor form is closed. Therefore, I'd like to call the method that does change the database on the OKButton click, if I could. The problem I'm facing is I don't know how.
Here is the DB code, we'll say the class is called DetailsConn:
public string editPin(int driverID)
{
if (SchemaChecker.PINAvailable())
{
string sql = "EditPIN";
using (SqlCommand cmd = new SqlCommand(sql, base.connection))
{
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.Remove("#nDriverID");
cmd.Parameters.AddWithValue("#nDriverID", driverID);
cmd.Parameters.Remove("#nPIN");
SqlParameter pinParameter = cmd.Parameters.Add("#nPIN", SqlDbType.Char);
pinParameter.Direction = ParameterDirection.Output;
pinParameter.Size = 32;
cmd.ExecuteNonQuery();
return pinParameter.Value.ToString();
}
}
return "";
}
Here's the code for my edit:
private void editToolStripMenuItem_Click(object sender, EventArgs e)
{
if (this.listViewDriverTags.SelectedItems.Count > 0)
{
ListViewItem lvi = this.listViewDriverTags.SelectedItems[0];
DriverTag driverTag = lvi.Tag as DriverTag;
else if (blahTag.blahType == 2)
{
buttonAssignPIN_Click(sender, e);
}
//message stuff and dialog boxes with localization info
if (dr == DialogResult.Yes)
{
this.listViewDriverTags.Items.Remove(lvi);
if (Tag.id != -1)
{
TagsToBeDeleted.Add(driverTag);
}
}
if (dr == DialogResult.No)
{
this.listViewTags.Items.Clear();
this.listViewTags.Items.Add(lvi);
}
}
}
Here's my buttonAssignPIN stuff:
private void buttonAssignPIN_Click(object sender, EventArgs e)
{
using (AssignPINForm form = new AssignPINForm())
{
if (form.ShowDialog(this) == DialogResult.OK)
{
DriverTag PIN = DriverTag.GetNewPIN(form.DriverTag);
ListViewItem lvi = this.listViewTags.Items.Add(PIN.driverTag);
lvi.SubItems.Add(this.TagTypes[PIN.TagType]);
lvi.Tag = PIN;
}
}
}
And finally, here's my AssignPINForm code:
public partial class AssignPINForm : Form
{
public AssignPINForm()
{
InitializeComponent();
this.buttonOK.Click += new EventHandler(buttonOK_Click);
this.buttonCancel.Click += new EventHandler(buttonCancel_Click);
this.buttonOK.Enabled = false;
this.textBoxPin.TextChanged += delegate(object sender, EventArgs e)
{
String pattern = #"^[0-9]{4,20}$";
Regex regex = new Regex(pattern);
buttonOK.Enabled = regex.IsMatch(textBoxPin.Text);
};
LoadStrings();
}
public void LoadStrings()
{
//stome stuff
}
public string DriverTag
{
get { return this.textBoxPin.Text; }
set { this.textBoxPin.Text = value; }
}
private void buttonOK_Click(object sender, EventArgs e)
{
}
private void buttonCancel_Click(object sender, EventArgs e)
{
this.Close();
}
private void AssignPINForm_Load(object sender, EventArgs e)
{
}
}
I know it's kind of all over the place but I've provided everything I think is relevant. The middle two snippets are in the same class too, and the DB stuff is the same solution but a different project. I'd be grateful if someone can decipher what I'm after and help me out, it's the only thing I have left to do on this particular bit!
Thanks!
Not sure I fully got what you're after and I agree with some of the comments that this isn't the best of practice but I guess what you're after is to update the buttonOK_Click method to something like this:
private void buttonOK_Click(object sender, EventArgs e)
{
using(DetailsConn connection = new DetailsConn())
{
int driver = -1;
if(int.TryParse(this.DriverTag, out driver)) {
connection.editPin(driver);
}
}
}
Also, you may want to remove any other possible references to the editPin() function.
I actually figured out that even if I got that working correctly, it wasn't going to solve my problem. I've had to call a new procedure and declare that in the database schema - basically it was a lot more complicated than what I was giving it credit for. Thanks for the responses nonetheless.
I have a combobox and want to save the changes in the database.
What I want to do is if the combobox is selected and it is true it must run the code below. If it is false it must then skip the code and go further.
The code below is checking if the combobox is enabled. But when I'm compiling it's saying true when not selected
private void Log()
{
if (kaartburgerlijkestand.Enabled)
{
veranderingBurgelijkestaat();
}
}
The code below is saving the data in the database
private string veranderingBurgerlijkestaat()
{
string gebruiker = curMedewerker.Behandelnaam;
string bekeken = prodermaform.pKaart();
string tabblad = tabControl1.SelectedTab.Text;
string pat = CPatient.GeefPatientNaam(patient.Id);
string wijz = "Burgerlijkestaat: " + kaartBurgerlijkestand.Text;
CDb dcon = new CDb();
try
{
if (dcon.Open())
{
SqlCommand cmd = new SqlCommand("INSERT INTO dbo.loggen(Gebruiker, Bekeken, Tabblad, Patientnaam, Wijziging, Datum) VALUES(#gebruiker, #bekeken, #tabblad, #pat, #wijz, #datum)", dcon.Conn);
cmd.Parameters.AddWithValue("#gebruiker", gebruiker);
cmd.Parameters.AddWithValue("#bekeken", bekeken);
cmd.Parameters.AddWithValue("#tabblad", tabblad);
cmd.Parameters.AddWithValue("#pat", pat);
cmd.Parameters.AddWithValue("#wijz", wijz);
cmd.Parameters.AddWithValue("#datum", DateTime.Now);
cmd.ExecuteNonQuery();
cmd.Dispose();
}
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
finally
{
dcon.Close();
}
return wijz;
}
Could someone show me a example how to do it
I Found the solution
I have made a check
private void doCheck(object sender, EventArgs e)
{
cmbox = false;
if (kaartBurgerlijkestaat.Focused)
{
veranderingBurgerlijkestand();
}
cmbox = true;
}
Then I used the SelectedValueChanged Event
private void kaartBurgerlijkestand_SelectedValueChanged(object sender, EventArgs e)
{
if (cmbox)
doCheck(sender, e);
}
And it works fine.
I want to thank you all for helping me!
Add an Event Listener, the kaartburgerlijkestand.Enabled only check your combobox is enabled to select or not.
Add this line after your InitializeComponent(); line of Form.cs file
kaartburgerlijkestand.SelectedIndexChanged += new System.EventHandler
(this.kaartburgerlijkestand_SelectedIndexChanged);
Also add a function for above code :
private void kaartburgerlijkestand_SelectedIndexChanged(object sender, EventArgs e)
{
veranderingBurgelijkestand();
}
