how do you properly instantiate an activeX control on aspx
 

hey... i currently making a web application, in VS 2008 - visual web developer 2008, for our final project and it makes use of an ocx which has methods to enable VOIP. What i did, since the control cannot be added to the tool box in order for it to be simply 'drag and drop'; i used aximp.exe to produce two dll's ATLH323Lib and AxATLH323Lib; i then referenced these two into my web application using Add Reference in the Solution Explorer.

My earlier error was that i always got an {ActiveX control 'fdd4c8c1-69c9-11d3-9dc8-525400e38cf9' cannot be instantiated because the current thread is not in a single-threaded apartment.} error when i did this... [code below]

namespace WebVOIP

{

   

    public partial class _Default : System.Web.UI.Page

    {

        //flags to know status of caller

        static bool inComingCall;

        static bool onTheLine;

       

        //variables in use

        static string newline = "\r\n";

       

        //Objects that handles the VOIP capabilites of the site



        private AxATLH323Lib.AxH323 ConnectionControl = new AxATLH323Lib.AxH323(); //ERROR points to this line

       

        protected void Page_Load (object sender, EventArgs e)

        {

            ConnectionControl.Listen();

           

            //ConnectionControl.ReceivingCall += new ATLH323Lib._IH323Events_ReceivingCallEventHandler(ConnectionControl_ReceivingCall);

        }



....



}

Then i tried to do it like this ... [code below]

namespace WebVOIP

{

   

    public partial class _Default : System.Web.UI.Page

    {

        //flags to know status of caller

        static bool inComingCall;

        static bool onTheLine;

       

        //variables in use

        static string newline = "\r\n";

       

        //Objects that handles the VOIP capabilites of the site



        private AxATLH323Lib.AxH323 ConnectionControl;

       

        protected void Page_Load (object sender, EventArgs e)

        {

            ConnectionControl = new AxATLH323Lib.AxH323();

            ConnectionControl.Listen();

           

            //ConnectionControl.ReceivingCall += new ATLH323Lib._IH323Events_ReceivingCallEventHandler(ConnectionControl_ReceivingCall);

        }



....



}

But then this error would appear... {Exception of type 'System.Windows.Forms.AxHost+InvalidActiveXStateException' was thrown.}

Help Please...
