COULD INVOKE A COM+ (CCW - .NET) FROM A CLIENT WITHOUT FRAMEWORK .NET INSTALLET

dotnet component services:

This is my COM+'s code:

using System;
using System.Text;
using System.IO;
using System.Reflection;
using System.EnterpriseServices;
using System.Runtime.InteropServices;

namespace Sgm.Interface
{
public interface ISampleSgm2
{
string Sistema {set;}
void Write();
}

[ProgIdAttribute("SampleSgm2")]
public class SampleSgm2 : ServicedComponent,
ISampleSgm2
{
public string _sistema = "";

public SampleSgm2(){}

public string Sistema
{
set {_sistema=value;}
get {return _sistema;}
}

public void Write()
{
String reg="";
FileStream fs = new
FileStream
("c:\\temp\\SampleSgm.log",
FileMode.Append);

DateTime dt = DateTime.Now;

reg=_sistema + " "+ dt.ToShortDateString()+"
"+dt.ToShortTimeString()+"\n";

byte[] text = ASCIIEncoding.ASCII.GetBytes(reg);

fs.Write(text, 0,
text.Length);

fs.Close();

}
}
}

I follow the next steps:

1.- sn -k XXXXXX.snk
2.- compile (VS-2002)
3.- regasm /tlb:XXXXX.tlb /codebase XXXXXX.dll
4.- gacutil -i XXXXXX.dll

and next ..

I create manually a application in Serviced Components (Server's
application)and I import this registered COM.

Finally I generated a proxy for the client.

Install de proxy in the client.

And I try this code in client, VB for application in excel

Dim obj As Object

Set obj=CreateObject("SampleSgm2")

... and I recive an exception ('242'Object required or '70'Not Allowed)
it depends of the proxy's configuration.

If someone have an idea that can helps me, I'll be interested to read
it.

Thanks.

Disable COM+ application security or add the calling account to the
COM+ role and enable the role for your component. It's best to use
static registration with regsvcs
