• How might you unobtrusively enhance the jQuery Datepicker class?

  - by Teflon Ted

  You can pass special strings into jQuery's Datepicker class setDate() method like "+7" which will be translated into "7 days from today": http://docs.jquery.com/UI/Datepicker#method-setDate But you can't get that "+7" back out. When you call getDate() you get the calculated resulting date. I have a use case where I need to pull out the special string "+7" for propagation. One chunk of code is passing a special string into the Datepicker and passing the Datepicker over to another chunk of code which pulls out the date, but the latter sometimes needs to know the special string rather than the calculated date. So I need to enhance the Datepicker tool to (a) store the special code internally and (b) expose it via a method like getOriginallyPassedInDate() or some such. I'm not a jQuery/Javascript ninja so I could really use some guidance on how I might preferably-unobtrusively add the necessary functionality to the Datepicker class, the way you might monkey-patch an object in Ruby I'm guessing.

• Java - Reg. Ex. File Question

  - by aloh

  I'm grabbing lines from a text file and sifting line by line using regular expressions. I'm trying to search for blank lines, meaning nothing or just whitespace. However, what exactly is empty space? I know that whitespace is \s but what is a line that is nothing at all? null (\0)? newline (\n)? I tried the test harness in the Java tutorial to try and test to see what an empty space is but no luck so far.

• Pass structured data from C++ app to ASP.NET web service.

  - by Odrade

  I have Visual C++ application that needs to communicate with a ASP.NET web service. Specifically, the app needs to pass structured data (e.g. objects that contain lists of structures, etc) as a parameter to one of the service methods. The C++ application is already generating an xml document that contains this data. The document is generating using an xml library, so it should always well-formed. What is a good method for passing this data to the web service? I'm thinking about passing the document to the web service as a string parameter, then deserializing to a .NET object based on an xsd. But, I hear that passing an xml doc as a string parameter is not recommended. So, my questions: What are the pitfalls associated with sending the document as a string parameter, assuming that the document itself is always well-formed? Assuming the above is a bad idea, what are some good alternate approaches?

• Convert Python 3.x snippet to C#/LINQ.

  - by Hamish Grubijan

  I want to sort elements of a HashSet<string> and join them by a ; character.

Many thanks!

• Accessing variablss through a different class within the constructor of latter classes of an object

  - by Haxed

  In the code below, I've added two lines that print output. The first line prints junk as usual, but surprisingly the second one gives me a compilation error. Why? class Student { private String name; public Student(String name){ this.name = name; } public String getName(){ return name; } } class StudentServer { public StudentServer(){ Student[] s = new Student[30]; s[0] = new Student("Nick"); // LINE 01: This compiles, although prints junk System.out.println(s[0]); // LINE 02: I get a error called cannot find symbol System.out.println(s[0].getName()); } public static void main(){ new StudentServer(); } } Many Thanks

• Urban Airship Tags issue

  - by Moshe

  I modified the alias sample code from: [request addRequestHeader: @"Content-Type" value: @"application/json"]; [request appendPostData:[[NSString stringWithFormat: @"{\"alias\": \"%@\"}", self.deviceAlias] dataUsingEncoding:NSUTF8StringEncoding]]; to: [request addRequestHeader: @"Content-Type" value: @"application/json"]; [request appendPostData:[[NSString stringWithFormat: @"{\"tags\": \"%@\"}", offsetStr] dataUsingEncoding:NSUTF8StringEncoding]]; offsetStr is a string containing a Timezone offset (which can be any number between -12 and 12). For some reason, Urban Airship is making each character of the string into its own tag. I've tried to substitute the - for a string neg with the same results. What's wrong?

• c++ Array passing dilemma

  - by Thomas

  Hi, I am writing a function that takes a string, string pointer and an int. The function splits the string based on a set of rules and puts each token into an array. I need to return the array out of the function with the number of elements in the int variable etc. I am stuck as to how I return the array as I can not use auto other wise it is destroyed and I am reluctant to use new as I feel this is patchy. I have other ideas on how to go about this but would like to see how other people go about this first. I could also be wrong and it could be possible to pass an auto out of an array. I can also not use vectors so there goes a copy constructor.

• Prevent Java from parsing the command line parameters

  - by User1

  Would like to make anapplication in Java that will not automatically parse parameters used on the command-line. Currently, java requires public static void main(string[]) as the entry point signature. I would like just a single string that I parse myself. Can this be done at all? Here's an example: java MyProgram.class Hello World I would want it to give me Hello World without requiring quotes around that string. I would even settle for java giving me the entire java MyProgram.class Hello World. I'm thinking this is something beyond Java and has more to do with the shell.

• Deserializing different named xml nodes

  - by Andreas

  Hi. Is there a way to convert different named xml nodes into one class when deserializing an XML Example XML: <items> <aaa>value</aaa> <bbb>value</bbb> </items> Normaly i would write: [XmlRoot("items")] class Items { [XmlElement("aaa")] public string aaa; [XmlElement("bbb")] public string bbb; } But now i would like to do something like this [XmlRoot("items")] class Items { [XmlElement("aaa")] [XmlElement("bbb")] public List<string> item; } Here I would love if "aaa" and "bbb" was added to the same list.

• Affine Transforms with Demo App

  - by Dex

  I have a demo app here https://github.com/rdetert/image-transform-test After importing an image, you can pinch, zoom, rotate the image. What I want to do is save out a 640x480 image (landscape mode) that looks identical to the live preview. So if there are 100px bars of empty space on the sides, I need the same empty bars in the final output (scaled appropriately). This is proving to be more difficult than I thought it would be. I can't quite get it to come out right after days of working on it. The magic method that generates the final image is called -(void)generateFinalImage Good luck! ;)

• Difference between ruby StringScanner post_match and rest?

  - by zhon

  What is the difference between ruby's StringScanner#post_match and StringScanner#rest? scanner = StringScanner.new('Say hello to...') scanner.scan(/\w+/) #=> 'Say' scanner.scan(/\s+/) #=> ' ' scanner.rest #=> 'hello to...' scanner.post_match #=> 'hello to...' scanner.rest.class #=> String scanner.post_match.class #=> String I don't see a difference. It seems like both return a string containing everything after the match.

• Return no records if FIndKey results in False?

  - by jwilfong

  Using TDataSet.FindKey you can locate records. When it results in True the datasets cursor will be positioned on the found record. When it results in False the cursor is not moved. This results in the record data prior to FindKey being issued being displayed in data aware components. How can I code the result of FindKey to return an empty record? if Not tblSomeTable.FindKey([SomeSearchData]) then begin < code to return empty or move data cursor to neutral position > end; Thanks, John

• Passing object through WCF so that server receives client changes

  - by cvig

  I would like to set up a WCF service so that any changes a client makes to an object I send them are also reflected on the server side. For example, if Assembly A has the following... namespace AssemblyA { public class Person { public string FirstName { get; set; } public string LastName { get; set; } } [ServiceContract] public interface IServer { [OperationContract] Person GetPerson(); } } And Assembly B references Assembly A... using AssemblyA; namespace AssemblyB { class Program { static void Main(string[] args) { <snip> IServer server = factory.CreateChannel(); Person person = server.GetPerson(); person.FirstName = "Kilroy"; person.LastName = "WuzHere"; } } } What is the easiest/best way to make it so that the service's copy of the Person object also reflects the changes that the client makes? Is this even possible?

• What is wrong with my version of strchr?

  - by Eduard Saakashvili

  My assignment is to write my own version of strchr, yet it doesn't seem to work. Any advice would be much appreciated. Here it is: char *strchr (const char *s, int c) //we are looking for c on the string s { int dog; //This is the index on the string, initialized as 0 dog = 0; int point; //this is the pointer to the location given by the index point = &s[dog]; while ((s[dog] != c) && (s[dog] != '\0')) { //it keeps adding to dog until it stumbles upon either c or '\0' dog++; } if (s[dog]==c) { return point; //at this point, if this value is equal to c it returns the pointer to that location } else { return NULL; //if not, this means that c is not on the string } }

  I must convert string of 1324312321 to array of integers in java this is fine. I could use integer parseint and string substring method but how do I repesent -12312312 to my original array of integer.. the fact that - is a char / string and convert to array of integer would alter the value ( even though I convert - to integer-equivalent , it would change the rest of 12312312) it must be an array of integers and how should I convert negative numbers and still keeep the same value somehow reminding me of two complements trick but i dont think i need to go down to binary level in my program.. any other trick for doing this? thanks!

• PHP - Can you help change this function slightly?

  - by Joe

  I have the following function I modified based off someone elses function: function showCombinations($string, $nameString, $linkParts, $i){ $wordDivider = "/"; //the divider between the words/values if ($i >= count($linkParts)){ echo "<a href='".trim($string)."'>".trim($nameString)."</a>, "; } else { foreach ($linkParts[$i] as $currentTrait){ if ($currentTrait['name']=="urltext"){ $currentNameStringName=""; //ignore } else { $currentNameStringName=$currentTrait['name']; } if ($nameString!=""){ $currentNameString=$nameString." - ".$currentNameStringName; } else { $currentNameString=$nameString.$currentNameStringName; } showCombinations($string.$currentTrait['value'].$wordDivider, $currentNameString, $linkParts, $i + 1); } } } showCombinations('', '', $linkParts, 0); All I need to change this to do is, instead of "ECHO", I want it to build up the combination and so I can do: $result = showCombinations('', '', $linkParts, 0); echo $result; I need it this way because I have to modify that $result, not just echo it.
