c# simple skype app throws COM exception

Question

I am making my first Skype app that can simply message a user but when I debug I get a exception that crashes my app. Here is the code:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using skype_app;
using SKYPE4COMLib;

namespace skype_app
{
    public partial class Form1 : Form
    {

        public Form1()
        {
            InitializeComponent();

        }

        private void Form1_Load(object sender, EventArgs e)
        {

        }



        private void button2_Click(object sender, EventArgs e)
        {
            var oskype = new SKYPE4COMLib.Skype();
            oskype.PlaceCall(textBox1.Text);
        }

        private void textBox1_TextChanged(object sender, EventArgs e)
        {

        }

        private void button1_Click(object sender, EventArgs e)
        {
           var oskype = new SKYPE4COMLib.Skype();
           oskype.SendMessage(textBox1.Text, textBox2.Text);
        }

        private void textBox2_TextChanged(object sender, EventArgs e)
        {

        }
    }
}

i have use some extra references references list:

Microsoft.Csharp
SKYPE4COMlib
SkypeDialoglib
system
system.core
system.data
system.data.DataSetEXTensions
system.deployment
system drawing
System.Windows.forms
System.xml.linq

Here is the exception i get: System.RUntime.InteropServices.ComException : {"connection refused"} So I guess my main question is why does my connection get refused when Skype dose not even open the dialogue asking if I want to allow the connection ?

the exseption get throwen at 'private void button2_Click(object sender, EventArgs e) { var oskype = new SKYPE4COMLib.Skype(); oskype.PlaceCall(textBox1.Text); }' — Gerard2202, Jul 10 '13 at 20:20
it would appear from your app that you haven't logged into Skype yet. Is this the case? — Chris, Jul 10 '13 at 20:21

The issue is that you're trying to debug in Visual Studio. Unfortunately, according to Skype themselves, they do not support using this API & debugging in VS:

Per the link:

The most comment cause for this is you are trying to debug the program in Visual Studio. Going forward we will not be able to support using the visual studio hosting process for debugging. You can turn it off by:

Open your project in VS

Open your projects properies

click the debug tab

untick "use visual studio hosting process"

rebuild your application and begin debugging and it should work ok.

Debugging in Visual Studio and Debugging using the [Visual Studio Hosting Process](http://msdn.microsoft.com/en-us/library/ms185331.aspx) are two very different things. – Scott Chamberlain Jul 10 '13 at 21:33
its ok i just built the solution the application was not supported in debug mode – Gerard2202 Jul 10 '13 at 22:15

i face the same issue. this way i solved it.

here is my code

Skype skype;
skype = new SKYPE4COMLib.Skype();
Call call = skype.PlaceCall(txtPhonenNo.Text);

first thing login to skype and go to Tools > option > advanced settings

your screen would look like enter image description here

click on manage other program's access to skype

then another window will come which will show all program name which try to access skype. if any exist just select all and remove it.

then run your program again and go to that screen where this option was available called click on manage other program's access to skype

click there and a windows will come which will display the name of your apps just select that name and click on change button then another window will come which looks like enter image description here

in that window just select the option called allow this program to access skype then a dialog come on the skype window which looks like enter image description here where you need to click on allow access button and then your job will be done. hope this will help.
