Say I wanted to display the number 123 with a variable number of padded zeroes on the front. For example, if I wanted to display it in 5 digits I would have digits = 5 giving me: '00123'. If I wanted to display it in 6 digits I would have digits = 6 giving: '000123'. How would I do this in Python? ...
Hello, I have some gaps in the understanding of string::assign method. Consider the following code: char* c = new char[38]; strcpy(c, "All your base are belong to us!"); std::string s; s.assign(c, 38); Does s.assign allocate a new buffer and copy the string into it or it assumes ownership of the pointer; i.e. doesn't allocate new mem...
So I have a problem that I can not figure out. I am writing some code in C. I kept winding up with issues where reading from the network would seemly randomly work. I finally traced it down to the number of strings in the code. I cant believe it but I have verified it pretty in depth. The code base is rather massive so I am not sure o...
Hi, This is a many discussed topic. But after searching for hours, I still could find how to do it... So, what I want is to render an anti-alias string on an SDL_Surface with a given alpha channel. It is possible to render: an anti-alias string with the Blended variant of the string render method. But then I can't make it transparen...
Is it possible to get an android cursor from an array (either ArrayList or StringaArray)? ...
Is this possible, or am I just trying to way overly shorten my code? I thought it might be something like: IQueryable<string> trimmedStrs = untrimmedStrsArr.AsQueryable<string>().All(s => s.Trim()); But that's no good :( ...
On Excel why putting a formula with the contents ="" sometimes make the replacement for an empty string and sometimes it places literally that text in the cell. Note: every cell of the worksheet is in the text format. ...
For some reason (it's a long story) I need to change the accents with their 'normal' counterparts. I'm doing this: $array = array( 'ò' => 'o', 'ó' => 'o', 'à' => 'a', 'è' => 'e', 'é' => 'e', 'ù' => 'u', ); return str_replace(array_keys($array), array_va...
Currently, whenever I pass a string to the db, if that string is empty, then i set that object to NULL by doing the following: IIf(DescriptionTxt.Text.length > 0, DescriptionTxt.Text, DBNull.Value) I was thinking about writing a function to reduce the length of this code, and make it more consistent. However, I was wondering, is ther...
I have an array of strings and an IQueryable (called MyTypeQbl). I want to iterate through the strings in the array which do not have a corresponding MyType.MyString. I thought this would be: foreach (string str in stringsArr.Where(s => MyTypeQbl.Count(m => m.MyString == s) == 0)) But is this just more complex than it should be? Is...
Hello I have an array of persons, and i am trying to sort them by age using a sort descriptor. The age field in a patient is a string so when calling: ageSorter = [[NSSortDescriptor alloc] initWithKey:@"age" ascending:YES]; [personList sortUsingDescriptors:[NSArray arrayWithObject:ageSorter]]; It sorts them but 100 appears first becau...
It is common knowledge that SameStr(S1, S2) is faster than S1 = S2, where var S1, S2: string in Delphi. (And, of course, SameText(S1, S2) is much faster than AnsiLowerCase(S1) = AnsiLowerCase(S2).) But, as far as I understand it, SameStr(S1, S2) does exactly the same thing as S1 = S2, so I cannot help but wonder why in the world the De...
I have two cell arrays of strings, and I want to check if they contain the same strings (they do not have to be in the same order, nor do we know if they are of the same lengths). For example: a = {'2' '4' '1' '3'}; b = {'1' '2' '4' '3'}; or a = {'2' '4' '1' '3' '5'}; b = {'1' '2' '4' '3'}; First I thought of strcmp but it would r...
I can get the compiler (msvc++ express) to convert "string" as a CustomString in a constructor, but not with a reference. Will it therefore not have the same chance of being optimized out with a pass-by-reference anyway, like passing by value with other types can, if the compiler thinks it can? won't implicit convert using new xmlNode...
What is the best way to convert a String to a ByteString in Haskell? My gut reaction to the problem is import qualified Data.ByteString as B import Data.Char (ord) packStr = B.pack . map (fromIntegral . ord) But this doesn't seem satisfactory. ...
I followed the great example at Python: Nicest way to pad zeroes to string (4) but now I need to turn that padded string to a padded integer. I tried: list_padded=['0001101', '1100101', '0011011', '0011011', '1101111', '0000001', '1110111', 1101111', '0111001', '0011011', '0011001'] # My padded sting list. int_l...
How do I find the sum of all the digits in a number in PHP? I've found solutions for C# and others, but not PHP. How do I do it? Thanks! ...
The following segment demonstrates my issue: (compilation error on GCC) stringstream ss; string s; ss << "Hello"; // This fails: // s.swap(ss.str()); // This works: ss.str().swap(s); My error: constSwap.cc:14: error: no matching function for call to 'std::basic_string<char, std::char_traits<char>, std::allocator<char> >::swap(std::...
d.getTime().toString().search(/Wed/i) I don't get it... typeof returns string, and if i copy and paste "Wed Jul 14 2010 15:35:53 GMT-0700 (PST)" and save it to the var str and do str.search(/Wed/i) it returns 0 but when i do it like above i always get -1, even tho, as i said, it returns a string typeof. Any ideas how to check if Wed i...
I'm having a very hard time trying to do something very simple. Here's the code: if(data == 'success') { alert('foo'); } else { alert(data); } I've simplified it, but that's all that's necessary to understand what's going on. the variable 'data' is a result of an AJAX call, if that m...
