Accessing COM object written in C# using JavaScript

Hello. I have an COM object that was written in C# using Visual Studio 2005. This is a COM object. I was able to instantiate this COM object using C++
code. (I had to import the tlb file at the top of the C++ file.)

Now I need to write JavaScript to access this COM object. The code I am using is this:
var myCOMObject = new ActiveXObject("progid");
catch (err)

where progid is the progid from the registry. (It's under KEY_CLASSES_ROOT\CLSID\(guid)\ProgID.

This is going into the catch block. The error it is getting (err.number) is -2146827859. I searched the Web, and this error code means "Automation server can't create object."

What am I doing wrong? I need to create this COM object in JavaScript.

- I did register the assembly using regasm.
- I know the COM object is defined because I can see it in the registry and I was able to access the COM object using C++. (I just can't access it in JavaScript.)

Many thanks in advance for the help.

C++ access violation when using JavaScript objects
Being completely new to Firefox extensions/plugins, XPConnect, and SpiderMonkey, I'm clearly missing a critical step and was hoping someone here could point me in the right direction. We have some existing C++ code we want to incorporate into a Firefox plugin so that Web pages can interact with our C++ using JavaScript embedded in the Web page. We're not trying to embed SpiderMonkey into our plugin...rather we need to use the native instance running in Firefox.

How to use a COM object written in C++ within PB
I need some help on how to use a COM object written in C++ saved as a xxx.DLL within PowerBuilder 6.5. We don't want to have to "deploy" this COM object to an application server, and have to create a "proxy" object to call it. we want to simply use this COM object from the file system where it resides, basically like an external function within a normal DLL.

How to get local app.config path for a .NET COM object used in aspx page
Hi all, We have an application with two parts: - An ASP.NET 2.0 web site - A VB.NET 2.0 class library (dll) which is compiled to be a COM component, so the public classes have a COM classid for each one. Most of the operations in the web site are run in the server (in the normal way), but a few operations have to be run locally in the client PCs which are running the web browser. To allow this, we use COM: we place <object> elements in the aspx pages, with the classids of the right library class. We install some files in the client PCs, including a local app.config...

use VB.NET and C#.NET code in the same C#.NET project
All-- Here is a sample that is "off the beaten path", (at least for me). Is it possible, in an ASP.NET application, using the code-behind page building technique, to have both pages written in VB.NET and pages written C#.NET?At there is a sample that shows that, (contrary to popular belief), it IS possible to mix ASP.NET pages built with C#.NET with ASP.NET pages built with VB.NET in the same VS.NET 2003 project. Note that this is just a "fun" sample to see if it can be done and I do not recommend this practice as a "standard" way of develo...
