Copying to clipboard from an aspx page

Try like this:

  protected void  CopyEmailToClipboard()
  {
    Thread.CurrentThread.SetApartmentState(Threading.ApartmentState.STA)
    Clipboard.SetText(txtEmail.Text)
   }

I changed the code to...
protected void  CopyEmailToClipboard()
 {
   Thread.CurrentThread.SetApartmentState(System.Threading.ApartmentState.STA)
   Clipboard.SetText(txtEmail.Text)
  }

Now I am getting this error...
Failed to set the specified COM apartment state

Could you please add this in your default.aspx.vb or .cs

Public Class abc    <STAThread()> _    Shared Sub Main(ByVal args As String())    End SubEnd Class

Partial Public Class _Default
    Inherits System.Web.UI.Page
.
.
.
.
.
End ..........

I will add it to default.aspx but I was wondering if it might be better in the MasterPage?

Okay I don't know about any thing regarding your project. So, If possible for you, adjust it.

By default there is no Main() method in an asp.net project. However, I added on. Here is what the code looked like after I added the Main() method you suggested to index.aspx.

using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using UserSession;
using MySchoolFeesMethods;

public partial class index : System.Web.UI.Page
{
private SessionVariables sv = new SessionVariables();
private MSF_Methods MSF = new MSF_Methods();

[STAThread()]
public static void Main(string[] args)
{
}

protected void Page_Load(object sender, EventArgs e)
{
// Set up session variables

// Direct to certain page based on variables
}

After doing this, this is the error that was thrown
System.InvalidOperationException was unhandled by user code

I think we should wait for someone else. I don't want to misguide you. :)

thanks for giving it a try! I do appreciate it. I am continuing to google. If I find the answer I will post it.

Here is how you do it...

It takes two methods to get the text into the clipboard.  The first method is your Click Method. The second method is the one that copies the text to the clipboard. You will notice that the name of the second method is referenced in the 1st line of the btnCopyToClipBoard_Click() method, I've bolded the place where you must reference the second method in the first. I hope that this is clear.

protected void btnCopyToClipBoard_Click(object sender, EventArgs e)
{
Thread t = new Thread(new ThreadStart(CopyEmailToClipboard));
t.TrySetApartmentState(ApartmentState.STA);
t.Start();
t.Join();
}

[STAThread]
protected void CopyEmailToClipboard()
{
Clipboard.SetText(txtEmailToUser.Text);
}

I thought that I had this problem whipped but I don't. When I run the web app locally it works great. However, when I publish it out to the web it fails.

Please don't close this thread. I thought that I had the problem figured out but the solution only works locally. Once I publish the site it fails. Thanks.

Yay, this thread is back open! Hello, hello, hello, is there anybody out there...

Basically what you are trying to do will be working but actually that is on Server side so you will not get it on client machine. I hope this is your problem. since you are doing R&D on local so server and client are on same machine so it worked well. for client side you need to create an activex object and read and write from that activeX control. Below discussion might help you.
