Hi,
I'm using the script editor in msn plus to load a dll I created using
Visual Studio (class library project in vb.net).

The code of the dll looks like this:
Public Class Msg
Public Sub New()

End Sub

Public Function Display() As Boolean
MsgBox("hello world")
Return True
End Function
End Class

and here is the call from the script (JScript) :
function OnEvent_ChatWndCreated(ChatWnd)
{
var externLib = MsgPlus.ScriptFilesPath + "\\msn.dll";
MsgPlus.DisplayToast("", externLib);
Interop.Call(externLib, "Display");

}

the error returned is :
Interop.Call could not locate the function "Display"

So I assume the dll was found but not the function withing the dll
Does anyone knows what could be wrong there ?
thanks
 
In case people are wondering why I'm posting msn jscript related code
on this forum, I just want to precise that obviously my question was
about the dll I wrote in vb.net ! not about the calling code...
So does anyone know what I should add/modify to this dll code so that
it can be recognised when called from my msn script ?
Just for info, I can load user32.dll from my msn script, so the trick
would be to make my vb.net dll look like user32.dll. What is specific
about it ?

Thanks
