  • Convert Enum to String

    - by Eric Weilnau
    Which is the preferred way to convert an Enum to a String in .NET 3.5? Enum.GetName Enum.Format toString Why should I prefer one of these over the others? Does one perform better? Justification for Accepted Answer Based on the forum post in panesofglass answer, it appears that Microsoft indirectly endorses the following method of converting an enum value to a string. Do not convert an enum value to a string using built-in enum methods. ... This will cause problems when Dotfuscating. You should not use enum.ToString(), enum.GetNames(), enum.GetName(), enum.Format() or enum.Parse() to convert an enum to a string. Instead, use a switch statement, and also internationalize the names if necessary.

  • PHP ucwords(): Uppercase the first character of each word in a string accept 'and', 'to', etc

    - by lauthiamkok
    hi, How can I make upper-case the first character of each word in a string accept a couple of words which I don't want to transform them, like - and, to, etc? For instance, I want this - ucwords('art and design') to output the string below, 'Art and Design' is it possible to be like - strip_tags($text, '<p><a>') which we allow and in the string? or I should use something else? please advise! thanks.

  • Why is this c++ string concatenation missing a space?

    - by danutenshu
    I am working with c++ strings, and am a beginner at programming. I am expecting: 99 Red Balloons But I am receiving: 99 RedBalloons Why is that? #include <string> #include <iostream> using namespace std; int main() { string text = "9"; string term( "9 "); string info = "Toys"; string color; char hue[4] = {'R','e','d','\0'}; color = hue; info = "Balloons"; text += (term + color + info); cout << endl << text << endl; return 0; }

  • Cannot access data in a xml string

    - by Jess McKenzie
    I am trying to create an array that I can include the perent category Name and the child category Name. I can so far access the below object fine using $xml->Subcategories; but if I try my code below I get an empty array why? PHP: foreach ($catDetailsXml->Category as $value) { $categoryDetails[] = array('CategoryNumber' => $value->Number); } Structure: object(SimpleXMLElement)#13 (1) { ["Category"]=> array(5) { [0]=> object(SimpleXMLElement)#14 (4) { ["Name"]=> string(19) "Commercial Property" ["Number"]=> string(10) "0350-0100-" ["Subcategories"]=> object(SimpleXMLElement)#35 (1) { ["Category"]=> array(3) { [0]=> object(SimpleXMLElement)#36 (4) { ["Name"]=> string(9) "Car parks" ["Number"]=> string(15) "0350-0100-8946-" ["Subcategories"]=> object(SimpleXMLElement)#39 (0) { } }

  • Python - Compress Ascii String

    - by n0idea
    I'm looking for a way to compress an ascii-based string, any help? I need also need to decompress it. I tried zlib but with no help. What can I do to compress the string into lesser length? code: def compress(request): if request.POST: data = request.POST.get('input') if is_ascii(data): result = zlib.compress(data) return render_to_response('index.html', {'result': result, 'input':data}, context_instance = RequestContext(request)) else: result = "Error, the string is not ascii-based" return render_to_response('index.html', {'result':result}, context_instance = RequestContext(request)) else: return render_to_response('index.html', {}, context_instance = RequestContext(request))

  • parsing/matching string occurrence in C

    - by David
    I have the following string: const char *str = "\"This is just some random text\" 130 28194 \"Some other string\" \"String 3\"" I would like to get the the integer 28194 of course the integer varies, so I can't do strstr("20194"). So I was wondering what would be a good way to get that part of the string? I was thinking to use #include <regex.h> which I already have a procedure to match regexp's but not sure how the regexp in C will look like using the POSIX style notation. [:alpha:]+[:digit:] and if performance will be an issue. Or will it be better using strchr,strstr? Any ideas will be appreciate it

  • Are pointers primitive types in C++?

    - by Space_C0wb0y
    I was wondering about the last constructor for std::string mentioned here. It says: template<class InputIterator> string (InputIterator begin, InputIterator end); If InputIterator is an integral type, behaves as the sixth constructor version (the one right above this) by typecasting begin and end to call it: string(static_cast<size_t>(begin),static_cast<char>(end)); In any other case, the parameters are taken as iterators, and the content is initialized with the values of the elements that go from the element referred by iterator begin to the element right before the one referred by iterator end. So what does that mean if InputIterator is a char * ?

  • C# enum to string auto-conversion?

    - by dcompiled
    Is it possible to have the compiler automatically convert my Enum values to strings so I can avoid explicitly calling the ToString method every time. Here's an example of what I'd like to do: enum Rank { A, B, C } Rank myRank = Rank.A; string myString = Rank.A; // Error: Cannot implicitly convert type 'Rank' to 'string' string myString2 = Rank.A.ToString(); // OK: but is extra work

  • Is there a way to define a List<> of two elements string array?

    - by Alexander Prokofyev
    I want to build two-dimentional array of strings where length of one dimention is 2. Similar to this string[,] array = new string[,] { {"a", "b"}, {"c", "d"}, {"e", "f"}, {"g", "h"} } Doing List<string[]> list = new List<string[]>(); list.Add(new string[2] {"a", "b"}); list.Add(new string[2] {"c", "d"}); list.Add(new string[2] {"e", "f"}); list.Add(new string[2] {"g", "h"}); list.ToArray(); gives me string[][] but not string[,] array. Just curious, is there some trick to build dynamically string[,] array somehow?

  • Forced closed only when put alphabetical string in edit text

    - by Abdullah Al Mubarok
    So, I make a checker if an id is in the database or not, the id is in numerical string, the type in database is char(6) though. So this is my code public class input extends Activity{ /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.input); final EditText edittext = (EditText)findViewById(R.id.editText1); Button button = (Button)findViewById(R.id.button1); button.setOnClickListener(new OnClickListener(){ @Override public void onClick(View arg0) { // TODO Auto-generated method stub String nopel = edittext.getText().toString(); if(nopel.length() == 0){ Toast.makeText(getApplicationContext(), "error", Toast.LENGTH_SHORT).show(); }else{ List<NameValuePair> pairs = new ArrayList<NameValuePair>(); pairs.add(new BasicNameValuePair("nopel", nopel)); JSON json_dp = new JSON(); JSONObject jobj_dp = json_dp.getJSON("http://10.0.2.2/KP/pdam/nopel.php", pairs); try { if(jobj_dp.getInt("row") == 0){ Toast.makeText(getApplicationContext(), "error", Toast.LENGTH_SHORT).show(); }else{ String snopel = jobj_dp.getString("nopel"); String snama = jobj_dp.getString("nama"); String salamat = jobj_dp.getString("alamat"); String sgolongan = jobj_dp.getString("golongan"); Intent i = new Intent(input.this, list.class); i.putExtra("nopel", snopel); i.putExtra("nama", snama); i.putExtra("alamat", salamat); i.putExtra("golongan", sgolongan); startActivity(i); } } catch (JSONException e) { // TODO Auto-generated catch block e.printStackTrace(); } } } }); } } the first check is to check if an input is null, it's going right for now, the second check is to check if an id in the database, and it's the problem. When I try some id in numerical value like "0001" or "02013" it's fine, and can run. but when I just got to put "abushd" it forced close. anyone know why I got this?

  • Why, in Ruby, does Array("foo\nbar") == ["foo\n", "bar"]?

    - by Tyson
    In Ruby 1.8.7, Array("hello\nhello") gives you ["hello\n", "hello"]. This does two things that I don't expect: It splits the string on newlines. I'd expect it simply to give me an array with the string I pass in as its single element without modifying the data I pass in. Even if you accept that it's reasonable to split a string when passing it to Array, why does it retain the newline character when "foo\nbar".split does not? Additionally: >> Array.[] "foo\nbar" => ["foo\nbar"] >> Array.[] *"foo\nbar" => ["foo\n", "bar"]

  • String Compression using Lempel-Ziv

    - by roybot
    Im looking for a way of compressing a given string using the Lempel-Ziv Algorithm. Preferably there would only be a set of two functions, encoder and decoder. The encoder takes the string and returns an integer. The decoder takes the integer and returns the original string. Time complexity is not important. How would you implement this?

  • Python Speeding Up Retrieving data from extremely large string

    - by Burninghelix123
    I have a list I converted to a very very long string as I am trying to edit it, as you can gather it's called tempString. It works as of now it just takes way to long to operate, probably because it is several different regex subs. They are as follow: tempString = ','.join(str(n) for n in coords) tempString = re.sub(',{2,6}', '_', tempString) tempString = re.sub("[^0-9\-\.\_]", ",", tempString) tempString = re.sub(',+', ',', tempString) clean1 = re.findall(('[-+]?[0-9]*\.?[0-9]+,[-+]?[0-9]*\.?[0-9]+,' '[-+]?[0-9]*\.?[0-9]+'), tempString) tempString = '_'.join(str(n) for n in clean1) tempString = re.sub(',', ' ', tempString) Basically it's a long string containing commas and about 1-5 million sets of 4 floats/ints (mixture of both possible),: -5.65500020981,6.88999986649,-0.454999923706,1,,,-5.65500020981,6.95499992371,-0.454999923706,1,,, The 4th number in each set I don't need/want, i'm essentially just trying to split the string into a list with 3 floats in each separated by a space. The above code works flawlessly but as you can imagine is quite time consuming on large strings. I have done a lot of research on here for a solution but they all seem geared towards words, i.e. swapping out one word for another. EDIT: Ok so this is the solution i'm currently using: def getValues(s): output = [] while s: # get the three values you want, discard the 3 commas, and the # remainder of the string v1, v2, v3, _, _, _, s = s.split(',', 6) output.append("%s %s %s" % (v1.strip(), v2.strip(), v3.strip())) return output coords = getValues(tempString) Anyone have any advice to speed this up even farther? After running some tests It still takes much longer than i'm hoping for. I've been glancing at numPy, but I honestly have absolutely no idea how to the above with it, I understand that after the above has been done and the values are cleaned up i could use them more efficiently with numPy, but not sure how NumPy could apply to the above. The above to clean through 50k sets takes around 20 minutes, I cant imagine how long it would be on my full string of 1 million sets. I'ts just surprising that the program that originally exported the data took only around 30 secs for the 1 million sets

  • how to copy char * into a string and vice-versa

    - by user295030
    If i pass a char * into a function. I want to then take that char * convert it to a std::string and once I get my result convert it back to char * from a std::string to show the result. I don't know how to do this for conversion ( I am not talking const char * but just char *) I am not sure how to manipulate the value of the pointer I send in. so steps i need to do take in a char * convert it into a string. take the result of that string and put it back in the form of a char * return the result such that the value should be available outside the function and not get destroyed. If possible can i see how it could be done via reference vs a pointer (whose address I pass in by value however I can still modify the value that pointer is pointing to. so even though the copy of the pointer address in the function gets destroyed i still see the changed value outside. thanks!

  • More elegant way to parse inline variables in strings

    - by Tom
    Currently I have this: function parse_string($string, $variables){ extract($variables); return eval('return "'. addcslashes($string, '"') .'";'); } So I can input this string: 'Hi {$name}, my name is {$own_name}' Together with this array: array('name' => 'John', 'own_name' => 'Tom') And get this back: 'Hi John, my name is Tom'   I've never liked this eval() approach but it works and it's fast (faster than regex at least). Question: Is there a more elegant way to do this (faster than using regex) in PHP5?

  • Python elegant inverse function of int(string,base)

    - by random guy
    python allows conversions from string to integer using any base in the range [2,36] using: int(string,base) im looking for an elegant inverse function that takes an integer and a base and returns a string for example >>> str_base(224,15) 'ee' i have the following solution: def digit_to_char(digit): if digit < 10: return chr(ord('0') + digit) else: return chr(ord('a') + digit - 10) def str_base(number,base): if number < 0: return '-' + str_base(-number,base) else: (d,m) = divmod(number,base) if d: return str_base(d,base) + digit_to_char(m) else: return digit_to_char(m) note: digit_to_char() works for bases <= 169 arbitrarily using ascii characters after 'z' as digits for bases above 36 is there a python builtin, library function, or a more elegant inverse function of int(string,base) ?

  • How do I not include part of a regular expression

    - by Axilus
    I'm pretty new to using regexes and I can figure out how I would go about extracted a specific number from a string. Suppose the string was any amount of whitespace or random text and somewhere within it is this, "Value: $1000.00." In order to retrieve that value I am currently using this: string value = Convert.ToString(Regex.Match(BodyContent, @"Value:[ \t]*\$?\d*(\.[0-9]{2})?", RegexOptions.Singleline)); So the variable 'value' now has, "Value: $1000.00" stored in it. My question is, using Regex is there a way to use 'Value:' to find the number value but only store the actual number value (i.e. 1000.00) in the 'value' variable?

  • Filtering python string through external program

    - by Peter
    What's the cleanest way of filtering a Python string through an external program? In particular, how do you write the following function? def filter_through(s, ext_cmd): # Filters string s through ext_cmd, and returns the result. # Example usage: # filter a multiline string through tac to reverse the order. filter_through("one\ntwo\nthree\n", "tac") # => returns "three\ntwo\none\n" Note: the example is only that - I realize there are much better ways of reversing lines in python.
