• String Functions in IIS Url Rewritting Module

  - by Nariman

  The IIS URL Rewrite Module ships with 3 built-in functions: * ToLower - returns the input string converted to lower case. * UrlEncode - returns the input string converted to URL-encoded format. This function can be used if the substitution URL in rewrite rule contains special characters (for example non-ASCII or URI-unsafe characters). * UrlDecode - decodes the URL-encoded input string. This function can be used to decode a condition input before matching it against a pattern. The functions can be invoked by using the following syntax: {function_name:any_string} The question is: can this list be extended by introducing a Replace function that's available for changing values within a rewrite rule action or condition?

• convert array of objects to concatenated string

  - by oo

  if i have: List<Car> where car is: public class Car { public int Year; public string Name; } and i want to take this array and create a concatenated string by "," so it would return: "Toyota", "Ford", "Chevy" i can do it manually like this: private static string CreateConcatenatedList(List<Car> parts_) { StringBuilder b = new StringBuilder(); foreach (Car bp in parts_) { b.Append(bp.Name + ", "); } b.Remove(b.Length - 2, 2); return b.ToString(); } but i thought there might be a more elegant way

• Bullet physics engine, how to freeze an object?

  - by Markus

  Using Bullet 2.76 I'm trying to freeze an object (rigid body) so that it instantly stops moving, but still responds to collisions. I tried setting it's activation state to DISABLE_SIMULATION, but then it's virtually nonexistent to other objects. Furthermore, if objects "collide" with it when it's disabled, strange things begin to happen (object's falling through static bodies, etc.) I suppose, temporarily converting it to a static rigid body could work, but is there an existing "native" way to achieve this on Bullet's side? Edit: Is there a way to turn off gravity for a specific object?

• more efficient way to pickle a string

  - by gatoatigrado

  The pickle module seems to use string escape characters when pickling; this becomes inefficient e.g. on numpy arrays. Consider the following z = numpy.zeros(1000, numpy.uint8) len(z.dumps()) len(cPickle.dumps(z.dumps())) The lengths are 1133 characters and 4249 characters respectively. z.dumps() reveals something like "\x00\x00" (actual zeros in string), but pickle seems to be using the string's repr() function, yielding "'\x00\x00'" (zeros being ascii zeros). i.e. ("0" in z.dumps() == False) and ("0" in cPickle.dumps(z.dumps()) == True)

• Using the same CArchive object for archive and un-archive

  - by bdhar

  Following is a sample code: CFile serFile; serFile.Open(_T("Person.ser"), CFile::modeCreate | CFile::modeWrite); CArchive writer(&serFile, CArchive::store); me.Serialize(writer); writer.Close(); serFile.Close(); serFile.Open(_T("Person.ser"), CFile::modeRead); CArchive reader(&serFile, CArchive::load); CPerson clone; clone.Serialize(reader); reader.Close(); serFile.Close(); Here, I have a writer which archives the object me. Then, I use another CArchive object reader to un-archive it. Is it possible to re-construct or set any property of writer to make it, the reader instead of declaring another CArchive object reader? Thanks.

• Efficiency of PHP arrays cast as objects?

  - by keithjgrant

  From what I understand, PHP objects are generally much faster than arrays. How is that efficiency affected if I'm typecasting to define stdClass objects on the fly: $var = (object)array('one' => 1, 'two' => 2); If the code doing this is deeply-nested, will I be better off explicitly defining $var as an objects instead: $var = new stdClass(); $var->one = 1; $var->two = 2; Is the difference negligible since I'll then be accessing $var as an object from there on, either way?

• SQLCe local db in temp- path in connectionstring?

  - by Petr

  Hi, I have SQL Ce db in my app, which is included in my app directory. While debugging its OK, but when published and run with setup.exe, it retrieves "file not found" in temporary directory the app is ran from. I would like to run from standard location, but I dont know how to change it. I am using this string: SqlCeConnection connection = new SqlCeConnection("Data Source=database.sdf;Persist Security Info=False;"); When I run setup.exe, the app never starts, stating that in its temporary directory the db file was not found. When I run app.exe, it works. I do not understand it...:( EDIT: I can see that in the VS project settings, there is connection string and there is "Data Source=|DataDirectory|\Database.sdf" The path should be something like local directory? Thanks!

• How do I convert a NSString into TIS-620 encoded string

  - by MacPC

  In the apple document, I can see that there's a way to convert from UTF8 string to ASCII string like this NSData *asciiData = [theString dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES]; NSString *asciiString = [[NSString alloc] initWithData:asciiData encoding:NSASCIIStringEncoding]; But my app requires a TIS-620 string to post to a site so I try to do the same thing NSData *asciiData = [newPost.header dataUsingEncoding:kCFStringEncodingMacThai allowLossyConversion:YES]; NSString *asciiString = [[NSString alloc] initWithData:asciiData encoding:kCFStringEncodingMacThai]; NSLog(@"%@", asciiString); The output I got is like this ???????????. Does anyone know how to convert the NSString to TIS-620 properly? Thanks so much.

• Regular Expression to return the contents of a HTML tag received as a string of text

  - by Nathan Hernandez

  I have a string in my code that I receive that contains some html tags. It is not part of the HTML page being displayed so I cannot grab the html tag contents using the DOM (i.e. document.getElementById('tag id').firstChild.data); So, for example within the string of text would appear a tag like this: 12 My question is how would I use a regular expression to access the '12' numeric digit in this example? This quantity could be any number of digits (i.e. it is not always a double digit). I have tried some regular expressions, but always end up getting the full span tag returned along with the contents. I only want the '12' in the example above, not the surrounding tag. The id of the tags will always be 'myQty' in the string of text I receive. Thanks in advance for any help!

  I am trying to check whether the string starts and ends with the same word. egearth. s=raw_input(); m=re.search(r"^(earth).*(earth)$",s) if m is not None: print "found" my problem is when the string consists only of one word eg: earth At present I have hard coded this case by if m is not None or s=='earth': print "found" Is there any other way to do this? EDIT: words in a string are separated by spaces. looking for a regex solution some examples: "earth is earth" ,"earth", -- valid "earthearth", "eartheeearth", "earth earth mars" -- invalid

• Doxygen C++ comment string parser in python?

  - by Sebastian

  Does anybody know of a python module to parse a doxygen style C++ comment string? I mean a string like this (simple example): /** * A constructor. * A more elaborate description of the constructor. * @param param1 test1 * @param param2 test2 */ and I would like to extract the brief, the long description, the parameters, the return value etc. I'm currently doing this using string methods and regular expressions but my solution is not very robust. Alternatively can anybody recommend an easy to use python parser lib that I can set up quickly? Thanks in advance

• moving EDMX file System.Data.MetadataException: Unable to load the specified metadata resource.

  - by Dani

  I have a ASP.NET MVC 2 project. I've created edmx file on the class library project that holds the model. now I've created another class library called it shared and moved the edmx file over there. resolved some issues, everything compiles, but it can't find the connection string resource at runtime. I've copied the ConnectionString part of the Web.Config to the main file, the old class library app.config file and the new class library app.config file. Still get this error: System.Data.MetadataException: Unable to load the specified metadata resource. Line 75: public myProjdb() : base("name=myProjdb", "MyProjdb") in the MyProj.Designer.cs file. Any Idea how to resolve this issue ? Is there a better way to store connection string data ?

• Attaching catalog with SQL Authentication credentials attaches it as Read-Only

  - by Nissim

  Hello, As part of our product's installation process, a database is attached to the server. We use EXEC sp_attach_db in order to attach it to MSSQL. The problem occures when we try to attach it with "SQL Authentication" connection string - the database is attached to the server as read-only, thus preventing any write access from being performed This is driving us nuts... it's working just fine with Windows Authentication, and the only difference is the connection string... I tried googling for it but no mention for such a scenario is found. Any ideas anyone? It's important to mention that the MDF/LDF physical files are not set with "ReadOnly" attribute, so this is not the problem.

• What happens to a class in PHP once its been instantiated?

  - by Caylem

  Hi I'm just playing around with some PHP and was wondering what happens when an object from a class is created within another PHP script? I assume once its created and been processed their is no way of then going back and 'playing' around with it from another script? The idea is i'm trying to create a kind of deck of cards using a card class, each card has specific data that is added to each individual object to make it unique, suit, value etc. Once its created i need to be able to go back to specific cards to use them. In java i'd have an arraylist of card objects, i'm not sure how to approach the same area in PHP. Thanks.

• Freeing JavaScript object

  - by pion

  I am looking at the example from http://www.javascriptkit.com/javatutors/oopjs.shtml var person = new Object() person.name = "Tim Scarfe" person.height = "6Ft" But there is no mention how to "free" it in order to avoid memory leak. Will the following code free it? person = null; How do you free a JavaScript Object using "new Object()? How do you free a JavaScript Array allocated using "new Array(10)"? How do you free a JavaScript JSON allocated using "var json = {"width": 480, "height": 640}"? Thanks in advance for your help.

• Check if a string substitution rule will ever generate another string.

  - by Mgccl

  Given two strings S and T of same length. Given a set of replacement rules, that find substring A in S and replace it with string B. A and B have the same length. Is there a sequence of rule application, such that it make string S into string T? I believe there is no better way to answer this than try every single rule in every single state. Which would be exponential time. But I don't know if there are better solutions to it.

• Updating an object with L2S with ASP.NET MVC

  - by Paul

  Is there an easier way to update an object with L2S other then doing it property by property? This is what I am doing now: Public ActionResult Edit(Object obj) { var objToUpdate = _repository.Single<Object>(o => o.id = obj.id); objToUpdate.Prop1 = obj.Prob1; objToUpdate.Prop2 = obj.Prop2; ... _repository.SubmitChanges(); } I am hoping there is a way to just say objToUpdate = obj then submit the changes??? Any help on this would be appreciated!

• C# COM+ component isn't getting the constructor string

  - by Kyle W

  I've created a COM+ component in C# with a strong name, COM Visible, ProgId, etc... I've then registered the assembly with regasm, and imported it into the COM+ Applications in Component Services. It runs just fine, and loads up the DLL, except that the constructor string that is passed in is always empty. The method signature is protected override void Construct(string constructString), and it is being called before the method on the actual component. In the component details in COM+ Applications, the constructor string is checked and a value is entered. Any help is appreciated.

• assignment vs std::swap and merging and keeping duplicates in seperate object

  - by rubenvb

  Say I have two std::set<std::string>s. The first one, old_options, needs to be merged with additional options, contained in new_options. I can't just use std::merge (well, I do, but not only that) because I also check for doubles and warn the user about this accordingly. To this effect, I have void merge_options( set<string> &old_options, const set<string> &new_options ) { // find duplicates and create merged_options, a stringset containing the merged options // handle duplicated the way I want to // ... old_options = merged_options; } Is it better to use std::swap( merged_options, old_options ); or the assignment I have? Is there a better way to filter duplicates and return the merged set than consecutive calls to std::set_intersection and std::set_union to detect dupes and merge the sets? I know it's slower than one traversal and doing both at once, but these sets are small (performance is not critical) and I trust the Standard more than I trust myself.
