.NET command called by LISP

[klonbeck]

I have a .NET app that calls wd_proj_wdp_data LISP API through a result buffer. If the app is called on the command line using the .NET defined command name everything works fine. I would like to the option to start my app by using the LISP command call, (command "commandname").

When I use the LISP command call the result buffer returns null. I don't know why it is returning null.

Why would the LISP command call prevent the result buffer from returning a value?

I am running AutoCAD Electrical 2016 on Windows 7

Hi,

are you using "LispFunction" ? if not, please try using LispFunction,

[LispFunction("MyLispFunction", "MyLispFunctionLocal")]
public int MyLispFunction(ResultBuffer args) // This method can have any name
{
          
    return 1;
}
