OK. So are any of the data you're sending to the database larger than the fields in the database?
Your code doesn't say what it's sending, how big, nor do you supply anything on the structure of the table you're updating.

Hey everyone, I am fairly new to learning c# and I wish to know how to make a C# Script to say when the player hits this collider then the next level starts.
Can you please let me know what I have done wrong in below?
Thanks for you help! 
Code I have currently:
using UnityEngine;
using System.Collections;
public class newLevelstarter : MonoBehaviour {
float OnTriggerEnter (){
Application.LoadLevel("Scene2"){
}
}
}
|
|
|
|
|
where is the code for Application.LoadLevel()?
and what is the problem or error?
|
|
|
|
|
I'm not exactly sure what that means. I was hoping someone had the same problem and was able to show me what they wrote to fix it. If not then I need to know how to fix it.
|
|
|
|
|
How to fix what? You have not shown any useful code, or explained what problem you are facing. If you are looking for sample code then you need to look in the Articles section, or try a Google search.
|
|
|
|
|
You haven't posted any code so you have nothing to fix. What you're actually doing is asking someone to write your code for you, that is something completely different.
|
|
|
|
|
I was just trying to find out what I did wrong and for someone to correct it. I'm just trying to make a simple level restarter that when a player hits a collider the level restarts?
|
|
|
|
|
You haven't done anything wrong; the problem is that you haven't done anything. If you have some code that does not work then you need to show it so someone can help you with it. What you have in your original question is not even started.

this is the code for restarting current level as i found on the net. so put this in any trigger, event , method or anything that want to restart the level. it may work 
Application.LoadLevel(Application.loadedLevel);
and also dont put '{}' for method calls just ';'

I am doing a TCP server & client communication. I would like to display the received data (from client) on the textbox of the server.
When i used txtStatus.AppendText, it works perfectly fine. But when i changed to txtStatus.Text, nothing was shown in the textbox.
I have tried changing to
txtStatus.Text += recMovementData.BaseMoveData.BaseMov.ToString();
but to no avail 
It should work as it is the same as .AppendText but it doesnt.
Can anyone help me with this?
This is my code for my server:
private void btnListen_Click(object sender, EventArgs e)
{
//IPAddress ipaddress = IPAddress.Parse(txtIP1.Text + "." + txtIP2.Text + "." + txtIP3.Text + "." + txtIP4.Text);
//int portNum = Convert.ToInt32(txtPort.Text);
IPAddress ipaddress = new IPAddress(new byte[] { 123, 123, 123, 123 });
int portNum = 8500;
TCPServerHelper.AcceptConnection(ipaddress, portNum);
txtStatus.Text = "Connected to remote client!";
while (true)
{
byte[] bufferReceivedData = TCPServerHelper.Read();
MovementData recMovementData = (MovementData)TCPServerHelper.Deserialize(bufferReceivedData);
try
{
//txtStatus.AppendText(recMovementData.BaseMoveData.BaseMov.ToString());
txtStatus.Text += recMovementData.BaseMoveData.BaseMov.ToString();
}
catch
{ }
}

Are you sure that the += operator is overridden for this property. I notice that you have an empty catch block in your code, which may well be why you don't see anything. There is no point using try/catch if you just ignore any exceptions.

I have an SQLite database with a column type of BLOB. But, here I inserted a text, because is a very long text and data types TEXT,STRING or VARCHAR does not support such a length. How can I show the text in a richTextBox? The code so far:
using (Conexiune.getConnection())
{
string select = "SELECT * FROM legislatie WHERE capitol = '" + SimulatorManager.LegislatieCapitol + "'";
SQLiteCommand cmd = new SQLiteCommand(select, Conexiune.getConnection());
cmd.CommandType = CommandType.Text;
SQLiteDataReader rdra = cmd.ExecuteReader(CommandBehavior.CloseConnection);
try
{
while (rdra.Read())
{
data = (byte[])(rdra["date"]);
}
}
catch (InvalidOperationException ex)
{
MessageBox.Show(ex.Message);
}
MemoryStream ms = new MemoryStream(data);
richTextBox1.Text = data.ToString();
}
|

Your code is vulnerable to SQL Injection[^].
NEVER use string concatenation to build a SQL query. ALWAYS use a parameterized query.
You're calling Conexiune.getConnection() twice, throwing away the result of the first call, and not disposing of the result of the second call.
You should wrap your disposable objects (the connection, command, and datareader) in using blocks.
You shouldn't use SELECT * FROM - state the column(s) you want to load explicitly.
There's no need to use a datareader to select a single value. ExecuteScalar will return the first column of the first row of the query results. You can also add a LIMIT 1 at the end of the query, since you're only looking at a single record.
To convert a byte[] array to a string, you'll probably need to the Encoding class[^]. Which encoding you use will depend on how your data was added to the database.
const string select = "SELECT data FROM legislatie WHERE capitol = @capitol LIMIT 1";
using (SqlLiteConnection connection = Conexiune.getConnection())
using (SqlLiteCommand cmd = new SqlListCommand(select, connection))
{
cmd.Parameters.AddWithValue("@capitol", SimulatorManager.LegislatieCapitol);
cmd.CommandType = CommandType.Text;
var data = cmd.ExecuteScalar() as byte[];
if (data == null || data.Length == 0)
{
richTextBox1.Text = string.Empty;
}
else
{
richTextBox1.Text = System.Text.Encoding.Default.GetString(data);
}
}

Hi everybody, i would like some help i am studying c#, however the text book i am studying from has examples that doesnt make any sense. Can someone please give me a example of how to use property in consuming classes. Thank you very much.

I'm not too sure what your actual problem is. Does the following help?
class ClassWithProperties
{
public string SomeProperty { get; private set; }
public ClassWithProperties(string someProperty)
{
SomeProperty = someProperty;
}
}
class ConsumingClass
{
public string SomeOtherProperty { get; private set; }
public ConsumingClass(ClassWithProperties cwp)
{
SomeOtherProperty = cwp.SomeProperty + "foo";
}
}
If not, please clarify.

hi to all and sorry for my bad english (im Italian).
i have a code (c#) for chat server and client using NetworksApi library. server and client works good but only in local (192.168.1.--).
what i would is the same operation but with public Ip (internet for far PC).
I tried putting the public IP and port number but nothing works.
here is my code for SERVER :
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 NetworksApi.TCP.SERVER;
using System.IO;
using System.Net;
namespace AdvanceServer
{
public delegate void UpdateChatLog(string txt);
public delegate void UpdateListBox(ListBox box,string value, bool Remove);
public partial class Form1 : Form
{
Server server;
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
server = new Server("192.168.1.6","90");
server.OnClientConnected += new OnConnectedDelegate(server_OnClientConnected);
server.OnClientDisconnected += new OnDisconnectedDelegate(server_OnClientDisconnected);
server.OnDataReceived += new OnReceivedDelegate(server_OnDataReceived);
server.OnServerError += new OnErrorDelegate(server_OnServerError);
server.Start();
}
Here is the code for CLIENT :
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 NetworksApi.TCP.CLIENT;
using System.IO;
using System.Net;
namespace AdvancedClient
{
public delegate void UpdateText(string txt);
public partial class Form1 : Form
{
Client client;
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
}
private void ChangeTextBox(string txt)
{
if (textBox1.InvokeRequired)
{
Invoke(new UpdateText(ChangeTextBox), new object[] { txt });
}
else
{
textBox1.Text += txt + "\r\n";
}
}
private void button3_Click(object sender, EventArgs e)
{
if (textBox3.Text != "" && textBox4.Text != "" && textBox5.Text != "")
{
client = new Client();
client.ClientName = textBox4.Text;
client.ServerIp = textBox3.Text;
client.ServerPort = textBox5.Text;
client.OnClientConnected += new OnClientConnectedDelegate(client_OnClientConnected);
client.OnClientConnecting += new OnClientConnectingDelegate(client_OnClientConnecting);
client.OnClientDisconnected += new OnClientDisconnectedDelegate(client_OnClientDisconnected);
client.OnClientError += new OnClientErrorDelegate(clien_OnClientError);
client.OnClientFileSending += new OnClientFileSendingDelegate(client_OnClientFileSending);
client.OnDataReceived += new OnClientReceivedDelegate(client_OnDataReceived);
client.Connect();
}
else
{
MessageBox.Show("E' obbligatorio completare tutti i campi");
}
}
anybody can help me ?
Thanks, Nick.

It may be blocked by your firewall, or perhaps you do not have a fixed IP address. Going through an ISP on auto-generated IP addresses does not work.
|
|
|
|
|
thanks Richard
so .... which could be the solution?
|
|
|
|
|
I connected my second PC with the phone (hotspot) and I identified public IP replacing it immediately to the local
|
|
|
|
|
That will not work, the 'public' IP only gets as far as the service provider. They then re-route the data to your broadband connection. If you wish to use a socket connection across the internet then you need to get a fixed IP address from your service provider.

I solved the issue.The 4.5 framework does not support destructor.
If someone use the destructor in the class file the solution build properly but the error occur when service is running.So it removed the destuctor and re-build.

How to Retrieve Image binary format data store in image
show the image Gridview
|
|
|
|
|
Use a BinaryWriter object.
Small Example:
using (var filestream = File.OpenWrite(file))
{
BinaryWriter bw = new BinaryWriter(filestream);
bw.Write(imagefieldhere, 0, (int)imagefieldhere.Length);
bw.Close();
}
In Word you can only store 2 bytes. That is why I use Writer.
