Pulling the Display name of an attribute from entity Metadata

I am fairly new at trying to get data from CRM using C#, I am trying to get the display names of all of my attribute on CRM, When I try, I am getting a result of Microsoft.Xrm.Sdk.Label and it doesn't seem to straight forward to get the value of that label, could someone point me in the right direction?
using System;
using Microsoft.Xrm.Tooling.Connector;
using Microsoft.Xrm.Sdk;
using Microsoft.Xrm.Sdk.Messages;
using Microsoft.Xrm.Sdk.Metadata;
namespace CRM_MetaData_Download
{
class Program
{
static void Main(string[] args)
{
try {
var connectionString = #"AuthType = Office365; Url = https://CRMINFORMATION";
CrmServiceClient conn = new CrmServiceClient(connectionString);
IOrganizationService service;
service = (IOrganizationService)conn.OrganizationWebProxyClient != null ? (IOrganizationService)conn.OrganizationWebProxyClient : (IOrganizationService)conn.OrganizationServiceProxy;
RetrieveEntityRequest retrieveEntityRequest = new RetrieveEntityRequest
{
EntityFilters = EntityFilters.All,
LogicalName = "account"
};
RetrieveEntityResponse retrieveAccountEntityResponse = (RetrieveEntityResponse)service.Execute(retrieveEntityRequest);
EntityMetadata AccountEntity = retrieveAccountEntityResponse.EntityMetadata;
Console.WriteLine("Account entity attributes:");
foreach (object attribute in AccountEntity.Attributes)
{
AttributeMetadata a = (AttributeMetadata)attribute;
Console.WriteLine(a.LogicalName + " " +
a.Description + " " +
a.DisplayName + " " +
a.EntityLogicalName + " " +
a.SchemaName + " " +
a.AttributeType + " "
);
}
Console.ReadLine();
}
catch (Exception ex)
{
Console.WriteLine(ex.ToString());
}
}
}
}

Since Dynamics CRM supports multi-lingual capabilities, the display name label will be stored for each language. You can get it like below:
a.DisplayName.UserLocalizedLabel.Label

Printing multiple lines in a text box/block .net c#

So what I'm trying to do is print outputs to a textbox but what's happening is it's always using the last textbox2.text it finds because I assume that each time I print it out it overrides the last output. I'm looking for some sort of work around

JArray players = (JArray)o["response"]["players"];
if (players.Count > 0)
{

string username = (string)players[0]["personaname"];

double LastLogOff = (double)players[0]["lastlogoff"];
int CurrentStatus = (int)players[0]["personastate"];
int GamePlaying = (int)players[0]["gameid"];
textBox2.Text = "your username is " + username + "\n";
textBox2.Text = "You last logged off on " + ConvertUnix(LastLogOff) + "\n";
if (PrivacyLevel == 3)
{
textBox2.Text = "This user's account is public";
}
else if (PrivacyLevel == 1)
{
textBox2.Text = "This user's account is private";
}
switch (CurrentStatus)
{
case 1:
textBox2.Text = "This user is offline";
break;
case 2:
textBox2.Text = "This User is online and playing";
break;
}
}
else
{
textBox2.Text = "You have entered the SteamID incorrectly";
}
Console.ReadLine(); // Don't remove you idiot
}
public static DateTime ConvertUnix(double unixTimeStamp)
{
// Unix timestamp is seconds past epoch
System.DateTime dtDateTime = new DateTime(1970, 1, 1, 0, 0, 0, 0, System.DateTimeKind.Local);
dtDateTime = dtDateTime.AddSeconds(unixTimeStamp).ToLocalTime();
return dtDateTime;
}
}
the output of this code will be the last textbox2.text so in this case it would be the switch statement. I know I haven't explained it the best but I just don't know why this is happening, Thanks

You should use textBox2.Text += "more text to be added to the text box" instead of textBox2.Text = "more text to be added to the text box"

The problem here is that by using textBox2.Text =, you're overwriting the value. Instead, if you want to add lines, use textBox2.Text += "myString";. This will append the string to the textbox instead of overwriting it.

you should use += operator after first equal.
textBox2.Text = "your username is " + username + "\n";
textBox2.Text += "You last logged off on " + ConvertUnix(LastLogOff) + "\n";
if (PrivacyLevel == 3)
{
textBox2.Text += "This user's account is public";
}
else if (PrivacyLevel == 1)
{
textBox2.Text += "This user's account is private";
}
switch (CurrentStatus)
{
case 1:
textBox2.Text += "This user is offline";
break;
case 2:
textBox2.Text += "This User is online and playing";
break;
}
}
else
{
textBox2.Text += "You have entered the SteamID incorrectly";
}

the answer is as they describe above but I would like to suggest that you use a
richtextbox since you have more than one message and it would be better if you display them in Separate lines to do so
richtextbox1.text="\r\n"+some string;
the "\r\n" is to go to new line and then insert the text in that new line
.

Getting all the items from the listbox winform

Good day!
I am having troubles on getting all the items, selected or not, from the listbox. Whenever I click the send button, the only items that I could get is the ones I selected (This is the current results of my code below: http://imgur.com/jA94Bjm). What I want is to get all the items from the textbox not just from the selected ones and which is not repeating.
private void cmd_send_Click_1(object sender, EventArgs e)
{
for (int i = 0; i < listBox1.Items.Count; i++)
{
try
{
String pno = textBox4.Text.ToString();
String path = textBox5.Text.ToString();
String name = textBox6.Text.ToString();
String user = textBox7.Text.ToString();
output.Text += "\n Sent data : " + pno + " " + user + " " + name + " " + path;
}
catch (Exception ex)
{
wait.Abort();
output.Text += "Error..... " + ex.StackTrace;
}
NetworkStream ns = tcpclnt.GetStream();
String data = "";
data = "--++" + " " + textBox4.Text + " " + textBox5.Text + " " + textBox6.Text + " " + textBox7.Text;
if (ns.CanWrite)
{
byte[] bf = new ASCIIEncoding().GetBytes(data);
ns.Write(bf, 0, bf.Length);
ns.Flush();
}
}
}

If you want to access all your items from your listbox, you have to iterate all of the items and access the value of that item. Here's a sample how you can achieve this:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
namespace ConsoleApplication1
{
class Program
{
class Process
{
public int ProcessId { get; set; }
public string FilePath { get; set; }
public string FileName { get; set; }
public string User { get; set; }
}
static void Main(string[] args)
{
Process p1 = new Process();
p1.ProcessId = 1;
p1.FileName = "Tool.exe";
p1.FilePath = #"C:\Tool.exe";
p1.User = "User1";
Process p2 = new Process();
p2.ProcessId = 2;
p2.FileName = "Tool2.exe";
p2.FilePath = #"C:\Tool2.exe";
p2.User = "User2";
Process p3 = new Process();
p3.ProcessId = 3;
p3.FileName = "Tool3.exe";
p3.FilePath = #"C:\Tool3.exe";
p3.User = "User3";
ListBox listBox = new ListBox();
listBox.Items.Add(p1);
listBox.Items.Add(p2);
listBox.Items.Add(p3);
for (int i = 0; i < listBox.Items.Count; i++)
{
Process p = (Process)listBox.Items[i]; //Access the value of the item
Console.WriteLine("Process id: {0}", p.ProcessId);
Console.WriteLine("Process filename: {0}", p.FileName);
Console.WriteLine("Process file path: {0}", p.FilePath);
Console.WriteLine("Process user: {0}", p.User);
}
Console.ReadLine();
}
}
}
We have a sample class Process with different properties. Each Process is added on ListBox which is later accessed inside the loop.

mono-service keeps reserving memory untill raspberry pi is out of mem

So I have a background service written in C# which connects to a RFID-reader and reads out all the tags he sees. After that the service will place all tags in a database running on the Raspberry Pi as well. The problem is when I start the service that it keeps consuming more and more memory from the Pi. I've already ran it with mono-service --profile=default:alloc but this returns errors. Does anybody see anything in my code which could cause this memory usage?

MaasOne yahoo-finance-managed returning zero results for AlphabeticIDIndexResult

I am trying to use http://code.google.com/p/yahoo-finance-managed/ to retrieve a list of all stock ids
with the following code:
using MaasOne.Base;
using MaasOne.Finance.YahooFinance;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace Elance___Yahoo_Finance_Symbols
{
class Program
{
static void Main(string[] args)
{
AlphabeticIDIndexDownload dl1 = new AlphabeticIDIndexDownload();
dl1.Settings.TopIndex = null;
Response<AlphabeticIDIndexResult> resp1 = dl1.Download();
Console.Write("Id|Isin|Name|Exchange|Type|Industry");
foreach (var alphabeticalIndex in resp1.Result.Items)
{
AlphabeticalTopIndex topIndex = (AlphabeticalTopIndex)alphabeticalIndex;
dl1.Settings.TopIndex = topIndex;
Response<AlphabeticIDIndexResult> resp2 = dl1.Download();
foreach (var index in resp2.Result.Items)
{
IDSearchDownload dl2 = new IDSearchDownload();
Response<IDSearchResult> resp3 = dl2.Download(index);
int i = 0;
foreach (var item in resp3.Result.Items)
{
Console.Write(item.ID + "|" + item.ISIN + "|" + item.Name + "|" + item.Exchange + "|" + item.Type + "|" + item.Industry);
}
}
}
}
}
}
but the
Response<AlphabeticIDIndexResult> resp1 = dl1.Download();
is always returning zero results...
Does anyone know what might be wrong please?
Thanks

I have an app using this API that's been working for about a year, and I see the same issue as of yesterday. :( Perhaps Yahoo changed their API, which would really suck.
