Console app and microsoft.win32

What happens when you try to run it ? Does it throw any exceptions ?

> I can run the app locally, but when I run it on a basic pc...

  Is the "basic pc" accessing the application from the network?  If so, can you try copying the application to the (C:) drive of the basic pc, and try again?

Window pops up:
common language runtime debugging services
application has generated an exception that could not be handled.
process id = 0x6f4(1780), thread id=0x400(1024)

On the command line:
Unhandled Exception: System.NullReferenceException: Object reference not set to
an instance of an object.
   at Application.class1.Main(String[] args)

The app is running locally on the test pc.  

What operating systems are the two PCs running?

win 2000 on the test pc.  win xp on the development machine (the that works).

But I just tried the exe on another test pc with win xp, and that didn't work.

Can you verify that your Registry calls would actually successful on another machine (i.e. check the registry on the test machine to make sure the keys you are looking up actually exist, or if you are making modifications then make sure you have the appropriate permissions)?

If you are still stuck, a post with some more code from your Main method would be helpful.

I'm thinking that it has something to do with .net framework and how on the test pc's its quite limited.

Is there a dll out there that contains the same methods and such thats in the microsoft.win32 namespace?

It may be a permissions issue that your code doesn't currently handle rather than there being something missing. Are you running the app under an Administrator account on all the machines ?

I"m logging in as the admin on the test pc's...  so permissions are valid.

yes, registry folder exists.

Here's the whole section that doesn't work...  you should be able to compile with no issues.  Just confirm you have the path first.  and just does a read, no modification at all.

                              OurKey = OurKey.OpenSubKey("Software\\Microsoft\\Windows Nt\\CurrentVersion\\Windows Messaging Subsystem\\Profiles\\Outlook\\"+ KeyName,false);

                              foreach(string valuename in OurKey.GetValueNames())
                              {
                                    if(valuename == "001e6608")
                                    {
                                          Console.WriteLine("\t\tValueName: "+ OurKey.GetValue(valuename).ToString());

                                          if(OurKey.GetValue(valuename).ToString() == "100")
                                          {
                                                Console.WriteLine("\t\tFOUND THE '100' VALUE");
                                          }
                                    }            
                              }
                        }
                  }
                  catch(Exception ex)
                  {
                        throw ex;
                  }
                  finally
                  {
                  }
            }
      }
}

Note that, you will also need to check that OurKey is not null before proceeding to call OurKey.GetValueNames.

Expert1701,

Thanks.  I found out that the path in the registry (depending on computer) changes for the last entry in the path.

I just wasn't looking far enough down in the tree.

Thanks for your help!
