I was doing a script with Perl and I came up with the following problem: I have to edit the name of a key in the Windows registry.
I'm using the module Win32::TieRegistry and searched at the documentation for any function, but didn't find it. I know that it should be easy, but can't find the way to do that. Any tip?
Thanks!
You can't change the name of a key in a hash, but you can copy the value to a new key and delete the old one.
$hash{new} = delete $hash{old};
This should work the same for a tied hash, assuming the implementation is sane.

I am trying to get the environment variable details of a particular user(non-administrator) from Administrator and when I was searching manually on registry editor found that its located under Computer\HKEY_USERS\S-..........\Environment. So came to the conclusion that I have to look for \HKEY_USERS\*\Environment and iterate each key to get the desired key and value. When I did google found that I have to pass the path for Win32::Registry::HKEY_USERS.open() and not suer how to pass the wildcard kind of value in the path. Any suggestion to get around this or if there is a better way (like getting the list of environment variables for the given username) to get the desired data that also would be great.
I'm trying to find something along the lines of insert_or_update (similar to what Laravel offers) in CodeIgniter 3. The closest I have found is $this->db->replace(), but I can't find anything that specifies that it can/can't be used alongside a ->where(). Based on the docs I don't believe this will work since it doesn't list ->where() as an option, but I wanted to double check this as well.
I'm hoping I can do something like...
$data = [...];
$whereSearch = [...];
$this->db->replace($data)->where($whereSearch);
The key here to quote the documentation is
using PRIMARY and UNIQUE keys as the determining factor.
Replace only works based on your keys to replace the values in a table. You might find Does replace into have a where clause? helpful as well.
$this->db->where('column_name',$compared_data);
$this->db->set('column_name',$updated_data);
$this->db->update('table_name');
Would this be what you're looking for?
I want to remove key from dictionary in Parse cloud code, as we can achieve this by calling removeObjectForKey: in objective-C. Sorry as this is very simple, but I am new to js, and also not able to find out solution for this.
As I have found the answer, so I am posting it for others, who want to do the same thing.By following command, we can do this
delete dictionary[key];
I'm rather new to Objective C (I'm using Xcode, if it's relevant). I tried to find an answer to this, but couldn't find anywhere...
My question is: Is there a possible way to change a variable name in the Localizable.strings file, so that it would change in the entire app?
I do not want to use the "search and replace" option, since if there are more instances of that string which are not this variable's name, they would change too (which is something I'm interested to avoid).
Basically I'm interested in finding the parallel function to java's "refactor", while using eclipse. Thanks to all helpers!
No, not possible to do it automatically. At least not in XCode - maybe AppCode can offer something, but I doubt it. Localizable.strings is not code - it's a text file which contains key-value pairs. Thus there are no real references to keys in your code, just same string values in your code and in the file.
I'm looking for a way to quickly edit and view my extension credential list (I use nsIPrefBranch to store it).
Is there any easy way to do that? I tried to look where that's stored but couldnt find it.
Many thanks!!
Got it,
