[RESOLVED] Help with registry

[daimous]

hi guys! im trying to add a subkey, "mySubKey", in LocalMachine but it wont work but when i try to add it in CurrentUser it works...any idea guys what the problem is? by the way, im login as administrator.

RegistryKey RegInfo = Registry.LocalMachine;
RegInfo.CreateSubKey("BCMDAlarm");
RegInfo.SetValue("StringName", "value");

What does "it won't work" mean? What actually happens?

[daimous]

Sorry for that. What i mean is, the subkey does not appear in LocalMachine(HKEY_LOCAL_MACHINE) after I executed the code above. But when I use .CurrentUser in lieu of .LocalMachine the subkey appears in HKEY_CURRENT_USER.

And you do have permissions and you receive no error whatsoever?

wouldnt you want your "BCMDAlarm" to actually be in the SOFTWARE folder...as in...

"HKLM\SOFTWARE\BCMDAlarm"

what you are trying to do is is create the following...

"HKLM\BCMDAlarm"

I didnt think you could write to the root HKLM key...(correct me if im wrong please...)?

Cheers, Justin

Oh! my fault. My code above is logically wrong..Because what I want is first, create a subkey "BCMDAlarm" in LocalMachine. Second, add Value "StringName" under subkey "BCMDAlarm" that I have just created. But what the code above will do is to create the value "StringName" under LocalMachine and not under "BCMDAlarm" subkey. I have the code here below is the right one.

string KeyName = @"SOFTWARE\BCMDAlarm";
RegistryKey RegInfo = Registry.LocalMachine;
RegInfo.CreateSubKey(KeyName);
RegInfo.Close();
Registry.SetValue(@"HKEY_LOCAL_MACHINE\" + KeyName, "Serial", "hisserial");

That's a little convoluted:RegistryKey key = Registry.LocalMachine.CreateSubKey(@"SOFTWARE\BCMDAlarm");

key.SetValue("Serial", "hisserial");
key.Close();
