I'm trying to show online/offline contacts from Skype, but I get an error:
An unhandled exception of type
'System.Runtime.InteropServices.COMException' occurred in
WindowsFormsApplication2.exe
Additional information: Retrieving the COM class factory for component
with CLSID {830690FC-BF2F-47A6-AC2D-330BCB402664} failed due to the
following error: 80040154.
Debugger says that an error is in: Skype skype = new Skype();

I found the solution.
Build -> Configuration Manager -> Acitve solution platform -> New -> x86 (instead of x64)
This helped.

Can someone help me with this code, at the line concerning the condition if I'm and Administrator it returns false despite logged in as Administrator.

Can someone help me adjusting the previous code so that the Rule is seen as Administrator?
I am trying to make an application with 5 virtual(hidden) Gecko(Xulrunner) Browser. But when I try to create one browser in Threading its return error at GeckoPreferences I am totally confused with it!
Here code Sample:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using DevExpress.XtraEditors;
using Skybound.Gecko;
using System.Threading;
namespace Gekco_Test

public partial class Main : DevExpress.XtraEditors.XtraForm
{
public Main()
{
InitializeComponent();
CheckForIllegalCrossThreadCalls = false;
}
private void Main_Load(object sender, EventArgs e)
{
}
private void simpleButton1_Click(object sender, EventArgs e)
{
Thread th = new Thread(webControllerFunc);
th.SetApartmentState(ApartmentState.STA);
th.Start();
}
void webControllerFunc()
{
geckoWebControl gControll = new geckoWebControl();
gControll.webBrowserAccess("91.213.108.178", 80);
}
}
class geckoWebControl
{
bool readyState;
GeckoWebBrowser wb = new GeckoWebBrowser();
public string webBrowserAccess(string host,int port)
{
Skybound.Gecko.Xpcom.Initialize(Application.StartupPath + "\\xulrunner\\");
readyState = false;
Form form = new Form();
GeckoPreferences.User["network.proxy.http"] = host;
GeckoPreferences.User["network.proxy.http_port"] = port;
GeckoPreferences.User["network.proxy.type"] = 1;
wb.Navigate("about:blank");
wb.DocumentCompleted += wb_DocumentCompleted;
while (!readyState)
Application.DoEvents();
return wb.Document.TextContent;
}
void wb_DocumentCompleted(object sender, EventArgs e)
{
readyState = true;
}
}
}
Error:
{"Unable to cast COM object of type 'System.__ComObject' to interface type 'Skybound.Gecko.nsIServiceManager'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{8BB35ED9-E332-462D-9155-4A002AB5C958}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE))."}
Thanks!
Gecko Doesn't support multithreading. So you can use it following code to use it in the threads.
this.BeginInvoke(new Action(() => {
//What you want gecko browser to do! Like:
geckoBrowser.navigate("http://somewhere.com");
}));

These instructions are for diagnosing this in WinDBG, a command line based debugger from microsoft, but I have been told they can work in Visual Studio.
Start up the application
Start up WinDBG and attach to the application
Type in ".loadby sos clr" (assuming >=4.0 framework)
Type "dumpheap -stat"
Look over the results, for suspicious objects type "dumpheap -mt {0}" where {0} is replaced by the objects MT address
If you don't know why objects are alive, type "gcroot {0}" passing an object address from above
my code is working fine but also I am receiving lot of WSAECONNRESET An existing connection was forcibly closed by the remote host. error.
I have a Chilkat.Socket Listener exe which is executing as a windows service and a test program which is simply sending strings data to this listener service. Listener is working fine but the program which is generatring strings and sending it to the listener is receiving the below mentioned error...please guide.
