Help with another key. (Almost done)!

Mar 5th, 2006

I've finally gotten this thing to open information and place it into a text file.
My next question is, how do I get this part to work? I've bolded the registry key that I'm trying to put into the notepad file, but this one just will not work. What am I doing wrong?

using System.Data;
using System.Collections.Generic;
using System.ComponentModel;

class Test 
{
    public static void Main() 
    {
        // Create an instance of StreamWriter to write text to a file.
        // The using statement also closes the StreamWriter.
        using (StreamWriter sw = new StreamWriter("SysInfo.txt")) 
{
            RegistryKey hklm = Registry.LocalMachine;
            hklm = hklm.OpenSubKey("HARDWARE\\DESCRIPTION\\System\\CentralProcessor\\0");
            Object obp = hklm.GetValue("Identifier");
            sw.WriteLine("Processor Identifier: " + obp);

         RegistryKey hklp = Registry.HKEY_CURRENT_USER;
            hklp = hklp.OpenSubKey("HKEY_CURRENT_USER\Software\America Online\AOL Instant Messenger (TM)\CurrentVersion\Users");
            Object obc = hklp.GetValue("Users");
            sw.WriteLine("Users: {0} ", obc);

            RegistryKey biosv = Registry.LocalMachine;
            biosv = biosv.OpenSubKey("HARDWARE\\DESCRIPTION\\System\\MultiFunctionAdapter\\4");
            Object obv = biosv.GetValue("Identifier");
            sw.WriteLine("Bios Status: {0} ", obv);

            RegistryKey biosd = Registry.LocalMachine;
            biosd = biosd.OpenSubKey("HARDWARE\\DESCRIPTION\\System\\");
            Object obd = biosd.GetValue("SystemBiosDate");
            sw.WriteLine("Bios Date: {0} ", obd);

            RegistryKey bios = Registry.LocalMachine;
            bios = bios.OpenSubKey("HARDWARE\\DESCRIPTION\\System\\");
            Object obs = bios.GetValue("Identifier");
            sw.WriteLine("System Identifer: {0} ", obs);
            sw.Close();

        }
    }
}

Basically I want it to place all those users on my computer into the file.

Whats the problem? you didnt say if there was an error.

What is the value in the registry? Is it a delimited text?

I think I'm using the wrong information to grab the key from the registry.
All it does it underline this part: HKEY_CURRENT_USER\Software\America Online\AOL Instant Messenger (TM)\CurrentVersion\Users in red and gives me this message: "Unrecognized escape sequence."

Thats because you made a mistake. In C# a \ is an escape sequence (used for special characters such as carriage return \r or new line \n). So a \ in a string is also a special character and so needs the escape sequence ie \\. As you see in your other reg strings (you left it out in this one).
The other way round it if you are not using special characters in your string is to use the @ symbol in front of the quotes which tells c# to take the string literally (beware if you use this then \r will appear as \r not a carriage return.

So your choices are
hklp = hklp.OpenSubKey(@"HKEY_CURRENT_USER\Software\America Online\AOL Instant Messenger (TM)\CurrentVersion\Users");

or

hklp = hklp.OpenSubKey("HKEY_CURRENT_USER\\Software\\America Online\\AOL Instant Messenger (TM)\\CurrentVersion\\Users");

both will work

hope it helps

Alright then. So now I have changed that part to

 Help with Code Tags 
 C# Syntax (Toggle Plain Text) 
            RegistryKey hklp = Registry.CurrentUser;
            hklp = hklp.OpenSubKey("HKEY_CURRENT_USER\\Software\\America Online\\AOL Instant Messenger (TM)\\CurrentVersion\\Users");
try
{
	Object obc = hklp.GetValue("Identifier");
	sw.WriteLine("Users: {0} " + obc.ToString());
}
catch (Exception exc)
{
	sw.WriteLine(exc.Message);
}
            RegistryKey hklp = Registry.CurrentUser;
            hklp = hklp.OpenSubKey("HKEY_CURRENT_USER\\Software\\America Online\\AOL Instant Messenger (TM)\\CurrentVersion\\Users");
try
{
	Object obc = hklp.GetValue("Identifier");
	sw.WriteLine("Users: {0} " + obc.ToString());
}
catch (Exception exc)
{
	sw.WriteLine(exc.Message);
}

Now when the program runs, it creates the file and everything, but in the part where it's supposed to have the AIM sign ons, it says "Object reference not set to an instance of an object."

Blah...this is frustrating. And I know I'm using the correct registry key path.

but you went and changed the key now.
it used to be
Object obc = hklp.GetValue("Users");
and now you just posted
Object obc = hklp.GetValue("Identifier");

be careful when you code you make mistakes if not paying attention. If it is frustrating then walk away for 30 minutes - you will come back refreshed.

Anyway, put the proper key in from your registry and it will work

Done, but it's still not working.
Apparently there's no way to get it to do that.
Oh well.

if you can see it in reg edit then it can be done in C#.
The trouble is i am working blind here as cannot see your registry etc and dont have AIM myself.
Can you tell me what the value is in your registry that you are trying to display? I dont need the names of your contacts, just whether it is a dword and a sample of the content (eg comma delimited string, or semi colon or what. Then i can help more

I made a screenshot for you...hopefully that will help you to see what I'm talking about.

I outlined the information I want in pink.

            RegistryKey hklp = Registry.CurrentUser;

try
{
string[] valnames = hklp.GetValueNames();
for (int i = 0; i < valnames.count; i++)
     {
	Object obc = hklp.GetValue(valnames[i]);
	sw.WriteLine("Users: {0} " + obc.ToString());
     }
