I am trying to save the username entered in the "enter playername" field in order to create a highscore list, can anyone help me with that ?
namespace TikTakTo
{
public partial class Anmeldung : Form
{
public Anmeldung()
{
InitializeComponent();
}
private void button_play_Click(object sender, EventArgs e)
{
Form1.setSpielerName(Spieler_1.Text, Spieler_2.Text);
Form1 frm = new Form1();
frm.Show();
this.Hide();
}
private void Spieler_2_KeyPress(object sender, KeyPressEventArgs e)
{
if (e.KeyChar.ToString() == "\r")
button_play.PerformClick();
}
}
}

Most recommanded option for windows-forms applications is a settings file located in the Properties folder.
The data there can be saved per-user and per-application, and stored in the application's AppData folder.You can read the settings-table fields, change their values and save your changes.
e.g:Properties.Settings.Default["SomeProperty"] = "Some Value";Properties.Settings.Default.Save();
Read this question for more info.

Basically you have two options, you can either save the info to file, or save it to database. This should help you: Best way to store data locally in .NET (C#)
Always try to make your own search before asking a question!

you can write in txt file in your project folder , and after restarting the app, you can control the file in that location , if its exist you can read data and put the form.
like a cookie.
example code.
public static string _debugPath { get { return Path.GetDirectoryName(System.Reflection.Assembly.GetEntryAssembly().Location); } }
public static void WriteToText(string txt)
{
DateTime _dt = DateTime.Now;
using (StreamWriter wr = File.AppendText(Path.Combine(_debugPath, "Info.Inc")))
{
wr.WriteLine(txt+"|");
wr.Close();
}
}
public static bool ReadInfo()
{
FileInfo fi = new FileInfo(Path.Combine(_debugPath , "Info.Inc"));
if (fi.Exists)
{
using (StreamReader rd = new StreamReader(Path.Combine(_debugPath , "Info.Inc")))
{
//take data in here and put the form.
}
}
}

I have a problem with the code in rec.Speechreconized += rec_Speachrecognized.
I have been looking for answers in the internet but it just won't work. I hope someone can help me.
namespace ai
{
public partial class Form1 : Form
{
SpeechSynthesizer s = new SpeechSynthesizer();
Choices list = new Choice {};
public Form1()
{
SpeechRecognitionEngine rec = new SpeechRecognitionEngine();
list.Add(new String[] {"Hello", "how are you"});
Grammar gr = new Grammar(new GrammarBuilder(list));
try
{
rec.RequestRecognizerUpdate();
rec.LoadGrammar(gr);
rec.SpeechRecognized += rec_Speachrecognized();
rec.SetInputToDefaultAudioDevice();
rec.RecognizeAsync(RecognizeMode.Multiple);
}
catch{return;}
s.Speak("Hi, I am Ms M, what can i help you?");
InitializeComponent();
}
public void Say(String h)
{
s.Speak(h);
}
private EventHandler<SpeechRecognizedEventArgs> rec_Speachrecognized(object sender, SpeechRecognizedEventArgs e)
{
string r = e.Result.Text;
if(r == "hello")
{
Say("hi");
}
throw new NotImplementedException();
}
private void Form1_Load(object sender, EventArgs e)
{
}
}
}

you need to change this line
rec.SpeechRecognized += rec_Speachrecognized();
to
rec.SpeechRecognized += rec_Speachrecognized;
basically remove the () at the end since the event will pass the params but this way you are calling the method without params

how to do that if user did not did anything on the website for a set amount of time the website will log out him?
is it from the c# page?
how can i tocount the time sincethe last touch on something?
and how can i alert it?
plss help
i want to add it here:
protected void Page_Load(object sender, EventArgs e)
{
if (Session["Conect"]!=null)
{
if (!(bool)Session["Conect"])
{
Response.Redirect("Must-Had.aspx", true);
}
}
else
Response.Redirect("Must-Had.aspx", true);
if (Session["val"]!=null)
{
if ((bool)Session["val"])
{
limission4.Visible = true;
mission4.InnerText =(string)Session["tit"];
}
}
if (Session["val2"] != null)
{
if ((bool)Session["val2"])
{
limission5.Visible = true;
mission5.InnerText = (string)Session["tit2"];
}
}
}

Place this somewhere between the <body> and </body> tags.
<script type="text/javascript">
var timeoutHandle = window.setTimeout("window.close();", 3000);
window.onscroll = function (e) {
window.clearTimeout(timeoutHandle);
timeoutHandle = window.setTimeout("window.close();", 3000);
}
</script>
You can change the "3000" to whatever amount of time you want the page to last.
You can also change the "window.close();" to whatever you want the page to do when the time runs out. The "window.close();" command will just close the page.

I'm making a shopping cart in asp.net with c# using DataTable stored in Session and all items stored in DataTable.
public DataTable dtCart = new DataTable();
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
if (Session["dtCart"] == null) { CreateCartTable(); }
}
}
protected void CreateCartTable()
{
dtCart.Rows.Clear();
dtCart.Columns.Clear();
dtCart.Columns.Add(new DataColumn("Prd_Id", Type.GetType("System.String")));
dtCart.Columns.Add(new DataColumn("Prd_Name", Type.GetType("System.String")));
dtCart.Columns.Add(new DataColumn("Prd_Img", Type.GetType("System.String")));
dtCart.Columns.Add(new DataColumn("Qty", Type.GetType("System.Int32")));
dtCart.Columns.Add(new DataColumn("Rate", Type.GetType("System.Decimal")));
dtCart.Columns.Add(new DataColumn("Amount", Type.GetType("System.Decimal")));
dtCart.Columns.Add(new DataColumn("TotalAmount", Type.GetType("System.Decimal")));
Session["dtCart"] = dtCart;
}
Is this right approach or any other way is more elegant and light on application?
FYI I'm using web forms.

You can make a class to cart:
public class Cart
{
public string Prd_Id{set;get;}
public string Prd_Name{set;get;}
//and so on...
}
then in page:
Cart obj=new Cart{Prd_Id="1",Prd_Name="John"};
Session["dtCart"]=obj;

I have asp webpage in Net4.0. In this version I can't use async method. I have ajax container:UpdatePanel . I have button in this panel. When I press button the page doesn't reload and in debug mode I see Page load method. I need filter ajax request and usual. How can I this do?
Like this:
protected void Page_Load(object sender, EventArgs e)
{
if(request.isAsync)
{
//this is ajax
}else
{
//this is usual request.
}
}

You can use extension method from here
public static bool IsAjaxRequest(this HttpRequest request)
{
if (request == null)
{
throw new ArgumentNullException("request");
}
return (request["X-Requested-With"] == "XMLHttpRequest") || ((request.Headers != null) && (request.Headers["X-Requested-With"] == "XMLHttpRequest"));
}
and make it:
if(request.IsAjaxRequest())
