What is the preferred way to remove spaces from a string in C++? I could loop through all the characters and build a new string, but is there a better way?
I am trying to parse a list of operating system instances with their unique identifiers. I am looking for a solution to parse a text string, and pass the values into two variables. The string to be parsed is as followed:

problem even happens when I try to match the string with regex.

Hi all,
I have a string as below:
"http:172.1." = (10, 1,3);

I have a dynamic php website which index only has around 800 errors according to the w3 validator online.
I have tried checking major websites like ebay, stackoverflow and others also, all with around 400 errors.
So my first thought is, what good is that validator when it always displays errors?
Secondly, will the errors affect my SERP ranking? ie, will me fixing these errors as good as I can increase my Google search position?
Thanks

I've built an API using actionwebservice and when a client calls a method to pass in an empty string (""), it's to_s value is # instead of "". But when the client passes in "hello", it's to_s value is "hello".
class UsersApiController < ApiController
web_service_api UserApi
def create_or_update(arg1)
Rails.logger.info arg1.to_s # Displays "#<SOAP::Mapping::Object:0x3a89c08>" if arg1 is an empty string
end
end
Let's say I have something like 30-10-2025 12:53, how could I convert that to an NSDate? I guess there's some class that takes this plus an format string that tells it how the date looks as a string, so it can parse it... where must I look?

Hi,
I want to check whether a string starts with any character in a list. My current implementation in C# is as follows:
char[] columnChars = new char[] { 'A', 'B', 'C', 'D', 'E' };
private bool startWithColumn(string toCheck)
{
for(int i=0; i<columnChars.Length; i++)
if (toCheck.StartsWith(columnChars[i]+""))
{
return true;
}
return false;
}
I would like to know if any solution is better?
Hi all,
I have a Windows Forms application (C#) containing a ListBox into which I have added some items (I'm not using a DataSource). I want to filter the items in the ListBox to show only items containing a string I'm searching for.
I have done this by keeping a list of the original items and selecting matching items from that list each time the searchstring changes and updating the ListBox.Items
Is there a more elegant/efficient way to do this?

I need to split this line string in each line, I need to get the third word(film name) but as you see the delimeter is one big blank character in some cases its small like before the numbers at the end or its big as in front of numbers at front.
I tried using string split with(" ") regex, and also \t but get the out of the bounds error.

Hello all ,
I have a string like "SAB_bARGS_D" . What I want is that the string gets divided into list of characters but whenever there is a _ sign the next character gets appended to the previous one.
So the answer to above should be ['S','A','B_b','A','R','G','S_D']
It can be done by using a for loop traversing through the list but is there an inbuilt function that I can use.....
Thanks a lot
I have the following dilemma: I have a list of strings, and I want to find the set of string which start with a certain prefix. The list is sorted, so the naive solution is this:
Perform binary search on the prefixes of the set, and when you find an element that starts with the prefix, traverse up linearly until you hit the top of the subset.
This runs in linear time, however, and I was wondering if anyone can suggest a more efficient way to do it.
Hi,
I want to execute a query like
select ID from "xyz_DB"."test" where user in ('a','b')
so the corresponding code is like
String s="(";
for(String user:selUsers){
s+= " ' " + user + " ', ";
}
s+=")";
Select ID from test where userId in s;
The following code is forming the value of s as ('a','b',)
