Hey, guys
Please see the code below:
/////*************** *************** *************** ***
RegistryKey rkHive = null;
RegistryKey rk = null;
string target = "127.0.0.1" ;
rkHive = RegistryKey.Ope nRemoteBaseKey( RegistryHive.Lo calMachine,
this.target);
try
{
rk = rkHive.OpenSubK ey(oro.key.Valu e);
//rkHive = {HKEY_LOCAL_MAC HINE}
//oro.key.Value=" \\SOFTWARE\\Cla sses\\.wax"
//And its data type is string.
}
//after the operation
//rk = null;
//It is abnormal as there is the right key in the right position
catch (System.Excepti on e)
{
Log(e);
}
//////*************** *************** *************** ********
We have some subkey below "HKEY_LOCAL_MAC HINE\\SOFTWARE\ \Classes\\.wax"
But after the operation the rk still equal to null and there isn't any
exception.
Has someone met the same situation? 2 2072
Hi Leo,
When you open a SubKey, you must not have the preseding //. In your case
oro.key.Value should be SOFTWARE\\Class es\\.wax, not
\\SOFTWARE\\Cla sses\\.wax.
Cheers,
Chester

I'm having an argument with an incumbent self-taught programmer that
it is OK to use null foreign keys in database design.
My take is the whole point of a foreign key is that it's not supposed
to be optional, it's very definition is it's a necessary link to the
parent table and part of the definition. If it's optional it shouldn't
be part of the definition of a table and should be in a linking table
instead.

Hello
I am trying to implement a search function within a collection of
Employees. I am searching for a specific EmpID number in the collection,
and if it is found, I want to return the Employee. This I can do.
The problem comes if the EmpID is not found in the collection. The only way
to achieve this I can think of is to throw an invalid argument exception:

Hi, all... Trying to determine how to check the state of OpenSubKey when
called. What is the return value if the requested subkey doesn't exist?? I
try a GetType on the result but only get a bizarre error, so I'm uncertain
what should be returned on both success or failure!
Thanks!

I remember there was a thread a while back that was talking about using the
return value of a function as a reference where I had thought the reference
would become invalidated because it was a temporary but it was stated that
it would not. This has come up in an irc channel but I can not find the
original thread, nor can I get any code to work.
Foo& Bar( int Val )
{
return Foo( Val );

This is incredibly strange. I used regedit and went to
HKEY_LOCAL_MACHINE and create a new subkey under "Software". I added
a few more, then went into code to try to read them. I kept getting
null returned when I tried to open them, so I decided to try this:
Registry.LocalMachine.GetSubKeyNames()
The results where dumbfounding--they did NOT match what I see in the
Registry under HKEY_LOCAL_MACHINE. The list values returned from the...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
