How do you call an external dll? I'm really confused. I'm using VB.NET to make the dll, and I'm registering it in the DotNetFiles section of the ScriptInfo.xml. However, each time I've tried to call a function from it, I get "Error: unknown."

I tried giving the DLL Name parameter of Interop.Call a nonexistant filename, and I get the same error with the same parameters as I did, with the same error code. This leads me to believe that Plus! cannot find my dll, however, everything I've tried gives me this same error.

So how can I make this work?

Interop.Call is for win32 dlls, not .NET ones.

I'm not sure what you need to use for .NET DLLs. Probably ActiveXObject().

Ah, I see. I'll try that soon.

EDIT: I can't seem to get this to work.

Hi,

I need to call an .Net Library, too, so I have the same problem...
Does anybody know a solution?

Edit: We can use the Included Com-Interop Services in .Net, but then it´s mindless from the developers of Plus! to differentiate between OLE and .Net Librarys...

JScript doesn't support .net objects natively so you have to use COM interop to access them. As long as you have the option checked in your project, you shouldn't see any difference at all . To instantiate your .NET object, just use new ActiveXObject().

What option? "Make assembly COM-Visible" ? And then we put it in <DotNetFiles> ? Also, how do I call it in ActiveXObject? Just ActiveXObject("MyDLL") ... or do I need something like ActiveXObject("MyDLL.Something-Else-Goes-Here") ?

Hi,

Pachou, why you doesn´t add a .Net-Scriptingfeature for Plus! Live?
The Framework offers many Runtime Support...

Using COM Interop in .Net is mindless! The objective of .Net it´s to supersede COM...

I'm still not catching this. BlackSun, if you got it, can you say something?

Hi,

You must use COM Interop attribtes, to "brand" your functions as COM compactible.
Then use the "Call" function to from you JScript to call your function...

If you don´t know about COM Interop, you should read here.

Well, I can set it as com-visible in the Assembly Information...is that it? Then just put it in DotNetFiles and use Interop.Call?
