I'm trying to add a clickable link to a rich text box that says something like "Start RDP" so when a user clicks on it, it will start windows remote desktop and use put the machine name in the box for you. Here is my code so far, It searchs Active Directory for a computer name that the user enters, pings the machine and if it is online, show its status in another textbox.
private void btnAd_Click(object sender, EventArgs e)
{
var adsb = new StringBuilder();
var mssb = new StringBuilder();
DirectoryEntry de = new DirectoryEntry();
de.Path = "LDAP://dc=Domain.org";
try

string wildcard = "*";
string adser = wildcard + txtAd.Text + wildcard;
DirectorySearcher ser = new DirectorySearcher();
ser.SizeLimit = System.Int32.MaxValue;
ser.PageSize = System.Int32.MaxValue;
ser.Filter = "(&(ObjectCategory=computer)(name=" + adser + "))"; //Only allows Computers to be returned in results.
SearchResultCollection results = ser.FindAll();
if (String.IsNullOrEmpty(txtcomputers.Text)) //if the textbox is empty, write ad search results to textbox
{
foreach (SearchResult res in results)
{
string[] temp = res.Path.Split(','); //temp[0] would contain the computer name ex: cn=computerName,..
adsb.AppendLine(temp[0].Substring(10));//returns everything after LDAP://CN= until end of temp[0].
if (Ping(temp[0].Substring(10)))
{
mssb.AppendLine(temp[0].Substring(10) + "....Online");
}
else
{
mssb.AppendLine(temp[0].Substring(10) + "....Offline");
}
}
rtbComputerstatus.Text = mssb.ToString();
txtcomputers.Text = adsb.ToString();
}
else //Add items to textbox if there are already items present.
{
txtcomputers.AppendText(Environment.NewLine);
rtbComputerstatus.AppendText(Environment.NewLine);
foreach (SearchResult res in results)
{

box.SelectionStart = jx;
box.SelectionLength = phrase.Length;
box.SelectionColor = color;

}

box.SelectionLength = 0;
}
//ping method
public static bool Ping(string hostName)
{
bool result = false;
try
{
Ping pingSender = new Ping(); PingOptions options = new PingOptions();
// Use the default Ttl value which is 128,
// but change the fragmentation behavior.
options.DontFragment = true;
// Create a buffer of 32 bytes of data to be transmitted.
string data = "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa";
byte[] buffer = Encoding.ASCII.GetBytes(data);
int timeout = 120;
PingReply reply = pingSender.Send(hostName, timeout, buffer, options); if (reply.Status == IPStatus.Success)
{

}
else

}
}

Any suggestions ? I've tried a few different things but can't seem to get it working.
Thanks !

Device Model: SpeedFace-H5L

When i use GetUserFaceStr I get all the templates but when I try to do SetUserFaceStr the operation fails and returns a -103 Error Code, In the documentacion it says that this error means "-103 device send back error of face version error"

It is a ZKteco error in SDK not compatible with device firmware. I faced same issue. It also happens with SpeedFace V4L
I try to enable/disable a specific USB device with C#.
I am a very confused because i found a lot informations, and they all contradict each other.

If you also prefer using WMI you can do it like this:
*Install Management NuGet
using System.Management;
*Add string with your device name/guid/deviceid.etc
public string DeviceName = "YourDeviceName";
*For Enable
ManagementObjectSearcher myDevices = new ManagementObjectSearcher("root\\CIMV2", #"SELECT * FROM Win32_PnPEntity where Name Like " + '"' + DeviceName + '"');
foreach (ManagementObject item in myDevices.Get())
{
ManagementBaseObject UWFEnable = item.InvokeMethod("Enable", null, null);
}
*For Disable
ManagementObjectSearcher myDevices = new ManagementObjectSearcher("root\\CIMV2", #"SELECT * FROM Win32_PnPEntity where Name Like " + '"' + DeviceName + '"');
foreach (ManagementObject item in smyDevices.Get())
{
ManagementBaseObject inParams = item.InvokeMethod("Disable", null, null);
}
#Edit:
You can also use devcon.exe from the Microsoft website.
I was able to achieve this by making use of the DevCon utility provided by Microsoft. The DevCon utility can be invoked by command line or with Process.Start(...).
I followed the example for disabling a device based on the device instance ID. Note that the ID argument begins with the "#" character. When I initially ran the command, I didn't notice this and it didn't enable/disable my device.
https://learn.microsoft.com/en-us/windows-hardware/drivers/devtest/devcon-examples?source=recommendations#example-31-disable-devices-by-device-instance-id
devcon disable "#USB\VID_045E&PID_0039\5&29F428A4&0&2"
i've got a server with all the logic of a four on row game of which i would like to display the state after each player turn i've got several class and i would like to send the game with the position played each turn,i succeded to send the first move to the client but the client just shoot down after that. the client and the server are both console application
in my main server side i've got this
var game = Game.CreateConsoleGame(DifficultyLevel.Hard, ActivePlayer.User, false);
game.Play();
Console.ReadKey();
those line are going to use other class Board,Game,Iodevice,judge and player
making all the logic of the game
in class player i've got this
and once i've got the position played ,i draw a String Builder
with this method
public static StringBuilder DrawStringBuilder(int nk)
{
cells = new CellStates[6, 7];
var builder = new StringBuilder();
var header = " 0 1 2 3 4 5 6";
var divisor = "-------------------------------------------------------------------";
builder.AppendLine(header);
builder.AppendLine(divisor);
int p = 0;
for (int i = 0; i < cells.GetLength(0); i++)
{
for (int j = 0; j < cells.GetLength(1); j++)
{
int counter1 = 0;
int counter2 = 1;
cells[5, nk] = CellStates.Player;
//cells[5, 0] = CellStates.User;
var str = cells[i, j] == CellStates.Empty ? "| ······· " : (cells[i, j] == CellStates.User ? "| 0 " : "| x ");
builder.Append(str);
counter1 = counter1 + 2;
counter2++;
}
builder.Append('|');
builder.AppendLine();
builder.AppendLine(divisor);
}
return builder;
}
i am just using this method
to send it to the client
public static void SendingPacket(StringBuilder packet)
{
IPAddress ipLocal;
IPEndPoint ipeLocal;
TcpListener List;
TcpClient tc = null;
NetworkStream ns = null;
string s2;
int n = 0;
try
{
ipLocal = IPAddress.Parse("127.0.0.1");
ipeLocal = new IPEndPoint(ipLocal, 8888);
List = new TcpListener(ipeLocal);
List.Start();
tc = List.AcceptTcpClient();
ns = tc.GetStream();
StreamReader reader = new StreamReader(ns);
StreamWriter write = new StreamWriter(ns);
string response = null;
//Console.WriteLine(response);
response = reader.ReadLine();
Console.WriteLine(response);
Thread.Sleep(200);
write.WriteLine(packet);
write.Flush();
n++;
Console.WriteLine("j'envoie");
Console.WriteLine("de player");
Console.ReadKey();
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
}
finally
{
if ((tc != null) && (ns != null))
{
tc.Close();
ns.Close();
}
}
}
for the client side i've got receveingdata method that i call in my main
why i can't receive at least twice my stringbuilder sent i'am getting an error
atthe second turn saying unable to read data from the transport connection an existing connection was closed by the distant host
public static void RecevingData()
{
IPAddress ipServeur;
IPEndPoint ipeServeur;
TcpClient tc = null;
NetworkStream ns = null;
try
{
ipServeur = IPAddress.Parse("127.0.0.1");
ipeServeur = new IPEndPoint(ipServeur, 8888);
tc = new TcpClient();
tc.Connect(ipeServeur);
ns = tc.GetStream();
string s = null;
string s1 = "ping";
string reponse = null;
StreamWriter write = new StreamWriter(ns);
StreamReader reader = new StreamReader(ns);
//Console.WriteLine("un string svp");
//s = Console.ReadLine();
write.Flush();
write.WriteLine(s1);
write.Flush();
do
{
reponse = reader.ReadLine();
Console.WriteLine(reponse);
} while (true);
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
Console.ReadKey();
}
}
i am a beginner so maybe my question is too stupid but i am just driven by getting better so please try to be indulgent,my idea was to send the stringbuilder the same way after each player's turn
I'm issue when I get +CDS in AT COMMAND throught c# using SerialPort, any times I get this +CDS truncated, example:

Please I really need help with it, I'm glad for any help!
+cds is alert for incoming message with message location on SIM memeory.
so here its seems in PDU mode data. and it is seems may be flash message content.
Convert the data PDU mode to Text mode to receive message.
review this ATSMS library
Here is a sample of my code.
Here I recieve a string variable from another page.
protected override void OnNavigatedTo(System.Windows.Navigation.NavigationEventArgs e)
{
base.OnNavigatedTo(e);
string newparameter = this.NavigationContext.QueryString["search"];
weareusingxml();
displayResults(newparameter);
}
private void displayResults(string search)
{
bool flag = false;
try
{
using (IsolatedStorageFile myIsolatedStorage = IsolatedStorageFile.GetUserStoreForApplication())
{
using (IsolatedStorageFileStream stream = myIsolatedStorage.OpenFile("People.xml", FileMode.Open))
{
XmlSerializer serializer = new XmlSerializer(typeof(List<Person>));
List<Person> data = (List<Person>)serializer.Deserialize(stream);
List<Result> results = new List<Result>();
for (int i = 0; i < data.Count; i++)
{
string temp1 = data[i].name.ToUpper();
string temp2 = "*" + search.ToUpper() + "*";
if (temp1 == temp2)
{
results.Add(new Result() {name = data[i].name, gender = data[i].gender, pronouciation = data[i].pronouciation, definition = data[i].definition, audio = data[i].audio });
flag = true;
}
}
this.listBox.ItemsSource = results;
}
catch
{
textBlock1.Text = "error loading page";
}
if(!flag)
{
textBlock1.Text = "no matching results";
}
}
Nothing is loaded into the list when the code is run, I just get the message "no matching results".
Looks like you are trying to do a contains search (my guess based on your addition of the * around the search string. You can remove the '*' and do a string.Contains match.
Try this.
string temp1 = data[i].name.ToUpper();
string temp2 = search.ToUpper()
if (temp1.Contains(temp2))
{
It looks like you are trying to check if one string contains another (ie substring match) and not if they are equal.
In C#, you do this like this:
haystack = "Applejuice box";
needle = "juice";
if (haystack.Contains(needle))
{
// Match
}
Or, in your case (and skip the * you added to the string temp2)
if (temp1.Contains(temp2))
{
// add them to the list
}
Have you checked to make sure data.Count > 0?
