I tried the following code in Visual C# 2010 Beta 2 on Win7Pro64. When I first
tried to add the references for JDLLServerLib and JEXEServerLib, I noticed that
the non-64 bit versions were listed in the Add Reference COM browser. I ran
jreg.bat from j64-602\bin. The code built and ran successfully with this
result:
>J DLL Test.exe"
J DoR ended with status 0 and result
1 1 1 1
0 1 0 1
0 0 1 1
0 0 0 1
===
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using JDLLServerLib;
using JEXEServerLib;
namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
// JDLLServerClass j = new JDLLServerClass();
JDLLServer j = new JDLLServer();
object result;
int status = j.DoR("2| !/~i.4", out result);
System.Console.WriteLine(string.Format("J DoR ended with status
{0}
and result\n{1}", status, result));
}
}
}
