I have a bunch of HTML + JS that currently uses a signed Java applet for reading/writing files to the hard disc.

I would like to remove my applet in favour of ActiveX.

In c++ I could overload the class which implements the calls to the COM / Active X object I used and add additionally member functions in the overloaded class.
How do that in c# with NET ? The "object" I get is only an interface with a CoClass. Deriving from the interface without implementation of all functions of the CoClass is not possible ... I dont have any dispatch pointer etc...
The member function should access a static Hashtable which returns some values.
Any Idea ?

Yes, but away from defining about 40 properties,functions get/set I dont know how to write them becouse:

The Interface class shows only the definitions like:
[DispId(0)]
string _Name { get; set; }

The CoClass similar like:
[DispId(0)]
public virtual string _Name { get; set; }

Which code to write into the class which inherits from the Interface ???
public class CMyClass : ICOMClass
{
public virtual string _Name { get { ??? }; set{ ??? }; }
....
I cannot leave the get/set empty but I dont have any parameters
Or how can I put something like a DispatchId and a dispatch pointer there ??

public class CMyClass : IComClass
{
    private IComClass m_Inner;

    public virtual string _Name
    {
        get {return m_Inner._Name;}
        set{m_Inner._Name = value}
    }

...

[CoClass CCOMClass]<br />
...<br />
public interface ICOMOuter : ICOMInner<br />
{ // not any character inside this interfaces {} <br />
}<br />
<br />
public interface ICOMInner<br />
{<br />
  [DispId1]<br />
  public string Property1 { get; set; }<br />
  ... etc.<br />
}<br />

public class MyClass : ICOMOuter<br />
{ ....<br />
}<br />

public class MyClass : ICOMOuter , ICOMInner<br />
{ ...<br />
}<br />

Does it create any specific kind of structure in the Registry under HKEY_CLASS_ROOT while registring the TLB file?
