The same code works fine on windows application but it does not work in Nav. Here is my sample code. please help me if i am doing anything wrong here.

I am working in c-sharp .net and I am working on creating a login screen for my project. I have a text file with login info for all the users. My c-sharp scrip reads that file to a string then cuts it up into two lists, _usernames and _passwords. When the user types their login info and hits login the _usernames[0] and _passwords[0] account info are the only ones that work. What I want it to do is look through all the _usernames for the inputted one, if it finds it then check the _password[same index as _usernames] and if both are the same as what the user submitted then it will add "true" to the richTextBox.
Why is it not correctly reading from the array?
This is my users.txt:
admin,test|
andrew,yeet|
zana,happy|
This is my c-sharp script:

rtbTemp.AppendText("\ntrue");

rtbTemp.AppendText("\nfalse");
}
public void GetLoginData()
{
using (StreamReader streamReader = new StreamReader(path, Encoding.UTF8))
{
data = streamReader.ReadToEnd();
}
List<string> _data = data.Split('|').ToList();
_data.RemoveAt(_data.Count - 1);
rtbTemp.AppendText("\n");
Array.Resize<string>(ref _usernames, _data.Count);
Array.Resize<string>(ref _passwords, _data.Count);
foreach (string _item in _data)
{
List<string> userdata = _item.Split(',').ToList();
string username = userdata[0].ToString();
string password = userdata[1].ToString();
Console.WriteLine(_item);
Console.WriteLine(username);
Console.WriteLine(password);

And this is an image of the login screen:

Your file contains carriage return characters. Remove them before you split its content
data = streamReader.ReadToEnd().Replace("\r\n", "");
Hello I was writing a basic text editor in C# on visual studio windows form using the .NET framework 3.1 long term support version everything worked fine until I wrote the save file script
Here's the code for "Form1.cs" which is where the open and save file functions reside
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.IO;
using System.Security.Principal;
namespace Text_Editor
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
string locsave;
private void openbtn_Click(object sender, EventArgs e)
{
var identity = WindowsIdentity.GetCurrent();
var principal = new WindowsPrincipal(identity);
if (principal.IsInRole(WindowsBuiltInRole.Administrator) != true)
{
MessageBox.Show("Run as Admin");
System.Windows.Forms.Application.ExitThread();
}
else
{
OpenFileDialog openfile = new OpenFileDialog();
if (openfile.ShowDialog() == DialogResult.OK)
{
var locationArray = openfile.FileName;
string location = "";
locsave = locationArray;
foreach (char peice in locationArray)
{
location = location + peice;
}
var contentArray = File.ReadAllText(location);
string content = "";
label4.Text = location;
foreach (char peice in contentArray)
{
content = content + peice;
}
richTextBox1.Text = content;
}
}
}
private void Form1_Load(object sender, EventArgs e)
{
Console.WriteLine("Test");
}
private void savebtn_Click(object sender, EventArgs e)
{
if (#label4.Text == "")
{
MessageBox.Show("Open a text file first");
}
else
{
StreamWriter outputfile = new StreamWriter(locsave);
outputfile.Write(richTextBox1.Text); //this is where the error occures and it throws the error of access denyed
outputfile.Close();
}
}
}
}
Does anyone have a suggestion about what to do I looked around on google for a solution but it seemed most did not work and some others I did not understand.
What I have is a medical record database that is accessed via PuTTY (SSH client). The cards themselves will only have Client name, record number in a barcode format (still determining the barcode type to be used), and client registration date.
1) We can get the data output as .zpl for Zebra Barcode label printers or formats compatible with laser printers like HP or Brother in a RAW format.
2) What output WILL the ZXP 3 SDK accept?
3) Can the SDK be set up to wait for and accept data coming at it using a command line from something like RedMon?
The cards themselves will only have the printed data, no mag stripe, smart chips, laminates or anything like that.
Mahalo in advance.
I would not recommend using either RedMon nor the SDK, as neither are required for what you are trying to do, and they both are time-vampires. Instead, I would write a small Windows Forms application which listens on a TCP port to receive the print job and send it to the standard printer which uses the Zebra driver.
Have the MUMPS application send an XML document via the Remote Print support in VT100. The example I have been using is below:
^[[5i
<patient>
<name first="John" last="Smith" />
<mrn>A04390503</mrn>
<dob>1991-03-12</dob>
</patient>
^[[4i
Configure a printer on the windows client to redirect to TCP/IP:
Add Printer
Local printer
Create a new port
Standard TCP/IP Port
Hostname: 127.0.0.1
Port name: CardFormatter
Uncheck "Query the printer and automatically select the driver to use"
Device type: Custom
Protocol: Raw
Port: 9101
Driver: Generic / Text Only
Start the application at logon, and print from the server. The MUMPS application will send back the XML, which Putty prints to the Text printer, which gets sent to the C# application on localhost. The C# application interprets the XML and prints to the actual printer via the Zebra driver or SDK.
Note: This only assumes one interactive session per workstation. If you are using fast-user-switching or terminal services, further care must be taken to ensure things work properly.
