I want to redirect to Home.aspx page but I am getting this error message:"System.Web.HttpException: Response is not available in this context" in the line of Response.Redirect("Home.aspx"); Any idea on solving this?
if ((strbuffer[11].ToString() == strCard1[11]))
{
UserID = "0000";
Send_Beep();
System.Diagnostics.Debug.WriteLine(("UserId: " + UserID));
comRFID.Close();
Response.Redirect("Home.aspx");
}
else
{
Response.Write("<script>alert('Card Undefined, Please Register Your Card.');</script>");
}

We need to see the context. Where is this code being called from?

Hi, this is my aspx.cs file:
private void comRFID_DataReceived(object sender, System.IO.Ports.SerialDataReceivedEventArgs e)
{
System.Diagnostics.Debug.WriteLine("comRFID_DataReceived");
comRFID.Read(hex, 0, hex.Length);
//Send_Beep();
System.Diagnostics.Debug.WriteLine("hex[0].ToString()");
System.Diagnostics.Debug.WriteLine("hex[1].ToString()");
System.Diagnostics.Debug.WriteLine("hex[2].ToString()");
System.Diagnostics.Debug.WriteLine("hex[3].ToString()");
System.Diagnostics.Debug.WriteLine("hex[4].ToString()");
System.Diagnostics.Debug.WriteLine("hex[5].ToString()");
System.Diagnostics.Debug.WriteLine("hex[6].ToString()");
System.Diagnostics.Debug.WriteLine("hex[7].ToString()");
System.Diagnostics.Debug.WriteLine("hex[8].ToString()");
System.Diagnostics.Debug.WriteLine("hex[9].ToString()");
System.Diagnostics.Debug.WriteLine("hex[10].ToString()");
System.Diagnostics.Debug.WriteLine("hex[11].ToString()");
string[] strCard1 = { "2", "12", "18", "128", "4", "0", "149", "124", "243", "50", "224", "243" };
//byte[] bytes = { hex[0], hex[1], hex[2], hex[3], hex[4], hex[5], hex[6], hex[7], hex[8], hex[9], hex[10], hex[11] };
string[] strbuffer = { hex[0].ToString(), hex[1].ToString(), hex[2].ToString(), hex[3].ToString(), hex[4].ToString(), hex[5].ToString(), hex[6].ToString(), hex[7].ToString(), hex[8].ToString(), hex[9].ToString(), hex[10].ToString(), hex[11].ToString() };
if ((strbuffer[11].ToString() == strCard1[11]))
{
UserID = "0000";
Send_Beep();
System.Diagnostics.Debug.WriteLine(("UserId: " + UserID));
comRFID.Close();
Response.Redirect("Home.aspx");
//Server.Execute("Home.aspx");
//HttpContext.Current.Response.Redirect("Home.aspx");
//Server.Transfer("Home.aspx", true);
}
else
{
Response.Write("alert('Card Undefined, Please Register Your Card.');");
Send_cmd();
}

So based on the name, that method is being called when data has been received from a serial port on the server - potentially some time after the page has finished executing and returned the response to the user.
The user is not still connected to the page, and there is no "response" to alter.
You need to read up on how ASP.NET works:

Hello,
I'm building a web application which involves using Google Translation.
The goal is to have the user enter the text into a text-box on my form, and then my code should take that string and enter it into Google Translate and retrieve translation. Any ideas how I can do that? Google Translator doesn't affect URL in any way when a query is entered or when a result is returned. It's completely in-page and URL independent, so I can't do anything there.
Any ideas?? I'm using VB.NEt
Thanks

Most likely you need to use an API or service provided by Google. Go to the Google developers website and see what features are available.

That's a better subject-line than cross-posted version in the C# forum. Alas, this one is missing the code-dump and will look cryptic.

And that's the problem...
You are a student, which means you are learning and need to practice. If you search for code "ready to go solutions" you are never going to learn as you should.
Facebook has a lot of very good professional programmers. Don't you think, this might be a bit too much for your level?

If something has a solution... Why do we have to worry about?. If it has no solution... For what reason do we have to worry about?
Help me to understand what I'm saying, and I'll explain it better to you
Rating helpful answers is nice, but saying thanks can be even nicer.

How is your project any reflection of your ability if you simply get the code elsewhere? If you get a job as a programmer and they want you to develop a hotel booking website what are you going to do? Search the net for hotel booking code? What if you can't find any or it doesn't meet client requirements?
No-one here is going to help you cheat your way to a qualification as we might end up working next to you one day.

I'm not sure what you are searching for but there are tons of examples online of how to do chatting using ASP.Net. You won't find anything you can copy and paste and be done with and I'm sure you wouldn't want that anyway.
So, get started writing the code. If you ever want a job programming you'll never be able to copy and paste entire projects of code off the internet. So, learn. Do.

Example: if I have a break line tag
<br/> in index2.aspx it is duplicated to many lines like this
<br/>
<br/>
<br/>
Please let me know how to solve this issue.
Thank You All

Are you talking about WebForms (because there is also ASP.NET MVC)?
Don't use Angular with WebForms; that's just dumb. They do the exact same thing, except one renders on the client and the other renders on the server.
