Help with registry, array, and listbox

[vbMark]

Hello,

In regards to the Registry...

Can someone give me an example of how to list an unknown number of subkeys
under a key, and put the key names in one column of a listbox, and the key
values in another column of a listbox?

Thanks!

Look at GetSubKeyNames( ), and GetValueNames of the RegistryKey object.

I know this isn't right but I know I'm close.
What do I need to do to fix this?

string[] strKeys;
string[] strValues;
RegistryKey rk = Registry.Curren tUser;
rk = rk.OpenSubKey(" Software\\Micro soft\\Windows\\ CurrentVersion
\\Internet Settings");
strKeys = rk.GetSubKeyNam es();
for (int i = 0; i < strKeys.Length; i++)
rk = strKeys.GetValu e(i);
listBox.Items.A dd(rk.GetValueN ames);

You are getting closer. One thing is, I'm not really sure what you're trying
to show to the user, so it's hard to be more helpful. But for starters, you
should understand that a key can hold subkeys, which can hold subkeys, etc,
etc; which at the bottom hold name value pairs. So not all keys will have a
single value which means anything if you can figure out a way to display it
in one line of a list box. In other words the depth of the registry is
unknown (at least to me.)

Now, your last try in code. You wrote RegistryKey rk = Registry.Curren tUser;
rk = rk.OpenSubKey(" Software\\Micro soft\\Windows\\ CurrentVersion
\\Internet Settings");
You're setting rk twice in two lines. Not necessary. (watch word wrap)

RegistryKey rk =
Registry.Curren tUser.OpenSubKe y(@"Software\\M icrosoft\\Windo ws\\CurrentVers i
on\\Internet Settings");
Console.WriteLi ne("Subkeys: " + rk.SubKeyCount) ; // = 10 on my machine
Console.WriteLi ne("Values: " + rk.ValueCount); //= 30 on my machine

then you have strKeys = rk.GetSubKeyNam es();

which returns all the subkeys which are like folders, and which may be what
you want, but I'm not sure. The names you get are other keys, which can
contain values and other keys. So I'm not sure what you get with the for
loop but it's probably not what you want.

On my machine, the key you open has ten subkeys, and 30 values, which are
different. The subkeys are like subfolders, and the values like files.

Once you figure out which it is you want, the subkeys or the values for a
key, you can load the list box using just two lines like
string[] keys = rs.GetSubKeyNam es();
listBox1.DataSo urce = keys;
