[C#] Plugin usable in COM?

[Chriso]

Does anyone know if it is possible to create a C# plugin which can be used in Visual Basic 6.0 using CreateObject()? If so, point me to a documentation on it please...

Thanks.

A plugin?  For what?

MBNCSUtil exposes objects to COM.  See: http://www.jinxbot.net/CodeBrowse/MBNCSUtil_1_3_1_8/Com/ICdKey.cs.aspx and http://www.jinxbot.net/CodeBrowse/MBNCSUtil_1_3_1_8/CdKey.cs.aspx.  Doing this, once you register the type library using regasm, you can use code along the lines of CreateObject("MBNCSUtil.CdKey").

Thanks, thats what I needed

One more question, how would I pass a COM object to .NET? I want to give the C# plugin access to the main form object in Visual Basic 6.0.

I'm not sure that's possible.  I don't know that a VB Form implements COM.

FrmMain.Hwnd?

[Chriso]

If I pass the handle to the plugin, would C# be able to convert it to an object and use its attributes?

C# calls the object System.__ComObject when it is sent to the plugin from Visual Basic, therefore it knows it is a COM element, one would assume you could access its attributes or create an Interface (maybe?) which contains the attributes you want to use.

Would I be able to do it with a class declared in Visual Basic?

[Imperceptus]

Not to be rude, I am curious why you want to do this from your first post.

As long as the class was an ActiveX object.

Hmm I assume VB6 Classes are ActiveX...?

[Barabajagal]

...no... ActiveX Classes are ActiveX. When creating a new project, you have the option to make a Standard EXE, ActiveX EXE, ActiveX DLL, or ActiveX Control (plus a lot of others). I'm fairly certain you can make an ActiveX DLL (which is basically a standalone Class) and then use it like a COM Plugin... I don't know, I've never dealt with plugins.. but it's starting to interest me due to a project I'm thinking of writing.

[Chriso]

True, I was pretty hungover when I wrote that lol.

Yeah I was just trying to extend my application to use C# plugins, I have got it working with all other type declarations except object's.

I don't think objects are interchangeable between languages... but I might be wrong.

You are in fact, like I pointed out in my first reply to this thread.
