How do I find if a string contains html data or not? (note: user provides input via rich:editor and its quite possible he could have used either a simple text or used html formatting)
I have 4 numeric up down controls on a form. They are set to hexidecimal, maximum 255, so they'll each have values from 0 to FF. I'd like to concatenate these values into a string for a textbox.
I have a string of HTML stored in a database. Unfortunately it contains characters such as ®
I want to replace these characters by their HTML equivalent, either in the DB itself or using a Find Replace in my Python / Django code.
Any suggestions on how I can do this?
Not sure whats going on here, or what could be the integer in this case. Here's the code:
def build_array_from_file(filename)
contents = []
File.read(File.expand_path('lib/project_euler/' + filename), 'r') do |file|
while line = file.get
contents << line
end
end
contents
end
filename is a string and I've checked to make sure the path comes up valid.
Any thoughts? Thanks.

I have strings like "5d4h2s", where I want to get 5, 4, and 2 from that string, but I also want to know that 5 was paired with d, and that 4 was paired with h, etc etc. Is there an easy way of doing this without parsing char by char?
I need to verify that the provided string has only allowed characters using Oracle regular expressions (REGEXP_LIKE).
Allowed chars are: abcdefghijklmnopqrstuvwxyz0123456789_-.
Trying to execute
SELECT CASE
WHEN REGEXP_LIKE('abcdefghijklmnopqrstuvwxyz0123456789_-.'
, '^[a-z0-9_\-\.]+$')
THEN 'true'
ELSE 'false'
END tmp
FROM dual;
results in 'false'.
Any ideas on this?

I want someone to type words in the console, and autocomplete from a list when they hit "tab" key. However, raw_input won't return a string until someone hits [Enter].
How do I read characters into a variable until the user hits [Enter]?
*Note: I don't want to use import readline for autocompletion because of OS issues.
It seems that if there is a sql memory leak somewhere and you dont have time to find it you can use the load balance timeout option in a sql connection string to destory the connection after x seconds.
Am i right in assuming I can set the load balance time out to 30-40 seconds and then hunt for the leak latter, while in the mean time the leak will not affect my application too much.

So are there any nice ways of getting the name of a predefined function as a string?

Hi, im traversing through the registry, taking the values of the keys and storing them as strings. I have discovered there are many different types. Some of these types are causing my filestream writer to fail. Is it possible to convert all of the below into a string form. The actual data value is not important, just the ability to differentiate between different values.
DWORD
ExpandString
Binary (is this just the same as byte[] ?)
MultiString
Trying to format a date string using a technique I've used countless times, suddenly returning false (PHP5). Anyone run into this?
//$new_date = June 14,2010
echo $new_date;
$new_date = date("F j, Y", strtotime($new_date));
//returns the infamous December 31, 1969 because strototime() is returning false?
