create a command with parameter

Anonymous — Fri, 23 Jun 2017 00:07:32 GMT

Dear All,

I want transmit a outside parameter to CAD, my thinking is like following :

//outside code

class xxxxx

{

//outside code

string parameter="ParameterToTransmit";

document acdoc.SendCommand("MyCommand ",ParameterToTransmit😞

}

//CAD command

[CommandMethod("MyCommand ")]
public static void MyCommand (ParameterToTransmit)
{

}

But i don't know how to make a command with parameter .

Is it possible to create a command with parameter ?

Or is it have other solution?

If you create a new ARX with the ObjectARX-Wizard, it will contain a lisp command called "MyLispFunction".

You find the implementation in acrxEntryPoint.cpp:

	static int ads_MyLispFunction () {
		struct resbuf *args =acedGetArgs () ;		
		// Put your command code here
		acutRelRb (args) ;
		
		// Return a value to the AutoCAD Lisp Interpreter
		// acedRetNil, acedRetT, acedRetVoid, acedRetInt, acedRetReal, acedRetStr, acedRetPoint, acedRetName, acedRetList, acedRetVal

		return (RTNORM) ;
	}

If you enter this command in AutoCAD: (mylispfunction "abc" 10 3.141 123456789)

args will be a resbuf list with the four arguments.

A different approach could be to implement a "normal" command that calls acedGetString(TRUE,NULL,argline) to retrieve arguments from the commandline. Than you have to parse argline yourself.
