Single-threaded apartment - cannot instantiate ActiveX control
I am developing a Asp.net template web based application in Visual Studio 2010. Aim of the application is to read the data from ID Tech card swipper.
#Default.aspx:
# It contain a Button
<asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent">
<h2>
<asp:Button ID="Button1" runat="server" Text="Button" OnClick="Button1_Click" />
</h2> </asp:Content>
Whereas following is .cs file:
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 AxOposMSR_CCO;
namespace WebApplication1
{
public partial class _Default : System.Web.UI.Page
{
AxOPOSMSR axOPOSMSR = new AxOPOSMSR();
protected void Page_Load(object sender, EventArgs e)
{
}
protected void Button1_Click(object sender, EventArgs e)
{
if (axOPOSMSR.Open("IDTECH_SECUREMAG_USBKB") == 0)
{
axOPOSMSR.ClaimDevice(100);
axOPOSMSR.DeviceEnabled = true;
axOPOSMSR.DataEventEnabled = true;
Console.WriteLine("cons called");
}
}
}
}
When i tried to run this project it shows:
ActiveX control 'ccb90122-b81e-11d2-ab74-0040054c3719' cannot be
instantiated because the current thread is not in a single-threaded apartment.
I googled it and it shows that i have to create an object of Active X control and use that object in my web application. I also followed some blogs and tutorial but didn't got any better explanation.
I am newbie in C#. What should i do to solve this issue?
Please explain me in the context of above application.
