Here's my code:
string[] strKeys;
RegistryKey rk = Registry.CurrentUser;
RegistryKey val = Registry.CurrentUser;
string sLocation = "Software\\Microsoft\\Windows\\CurrentVersion
\\Internet Settings\\P3P\\History";
rk = rk.OpenSubKey(sLocation);
strKeys = rk.GetSubKeyNames();
for (int i = 0; i < strKeys.Length; i++)
{
listBox.Items.Add( strKeys.GetValue(i) );
}
The above works to just display the Key names. However, when I try
to change the for loop to diplay the 1st value of each key I can not
get it to work. I've tried all sorts of things. Here is one example:
for (int i = 0; i < strKeys.Length; i++)
{
val = rk.OpenSubKey( sLocation + "\\" + strKeys.GetValue(i) );
sKey = strKeys.GetValue(i);
listBox.Items.Add( strKeys.GetValue(i) + " " + val.GetValue(sKey)
);
}
The above gives conversion error messages.
How do I make this work?
What error messages are you getting?
Could you post a short but complete program which demonstrates the
problem?
See

what I mean by that.
