Default InvalidActiveXStateException

Hello,

I am writing a control in C# that requires me to use an ActiveX control created in VB6. It works fine running from inside the IDE in both debug and release mode.

However, when I try to run an installed version, I get an InvalidActiveXStateException whenever I try to access a method or property of the ActiveX control. For instance, there is a connection property that is defined in the ActiveX control as:

Code:
Public Function Connect(Hostname As String, Port As Long, _
    Flags As Integer, UserName As String, _
    Password As String) As Integer


Inside the C# code, I call it like this:
Code:
    try
    {
        Result = axMyControl.Connect(ref m_HostName, 
        ref m_Port, ref Flags, ref m_UserName, ref m_Password);
    }
    catch (Exception e)
    {
    MessageBox.Show("Unable to connect to " + m_HostName + 
        "\n" + e.Message, "Connection Error",
            MessageBoxButtons.OK, MessageBoxIcon.Information);
    return;
    }


The exception is always thrown here (and anywhere else I try to access the code).

Any suggestions?

Thanks,
pagates
