  • I'm new to Java most basic question about arrays!

    - by ambidextorous
    Hey I have not been able to find a proper answer on any forums about this but how exactly do I pass an array to a class? public class TestArray { String name; String[] array; public TestArray(String name, String[] anArray){ this.name = name; int len = anArray.length; this.array = new String[len]; for (int i = 0; i < len; i++){ this.array[i] = new String(anArray[i]); } } } public static void main(String[] args){ String[] anArray = new String[2]; anArray[0] = new String("Test"); anArray[1] = new String("Test2"); TestArray work = new TestArray("Jordan", anArray?); } }

  • String vectors not working as expected with newline and iterators? (C++)

    - by kevin
    I have a text file made of 3 lines: Line 1 Line 3 (Line 1, a blank line, and Line 3) vector<string> text; vector<string>::iterator it; ifstream file("test.txt"); string str; while (getline(file, str)) { if (str.length() == 0) str = "\n"; // since getline discards the newline character, replacing blank strings with newline text.push_back(str); } // while for (it=text.begin(); it < text.end(); it++) cout << (*it); Prints out: Line 1 Line 3 I'm not sure why the string with only a newline was not printed out. Any help would be appreciated. Thanks.

  • Get the string "System.Collections.ObjectModel.ObservableCollection" from a Type (System.type) containing a generic ObservableCollection?

    - by Guillaume Cogranne
    I got a Type whose FullName is (if this helps) : "System.Collections.ObjectModel.ObservableCollection`1[[System.String, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]]" From that Type, I'd like to get "System.Collections.ObjectModel.ObservableCollection" as a string but I'd like to do it "cleanly", which means, without spliting the string with the char '`'. I think the strategy is to get something like a Type or something else whose FullName will be "System.Collections.ObjectModel.ObservableCollection" but I really don't manage to do it :/

  • How can I check a user/password combination on an ActiveDirectory without putting the password in a String?

    - by Jean Hominal
    I want to check User/Password combination on a Windows domain. Right now I do it with the following code: bool Login(String username, String password) { var principalContext = new PrincipalContext(ContextType.Domain); principalContext.ValidateCredentials(username, password); } While it works, the thing that bugs me is that I have to put the password in a String in order to use that API; as I am using a SecureString to store the password everywhere else, I would really like to use some way of checking the username / password combination without having to pass the password as a managed System.String. What would be the best way of achieving that?

  • LINQ - Splitting up a string with maximum length, but not chopping words apart.

    - by Stacey
    I have a simple LINQ Extension Method... public static IEnumerable<string> SplitOnLength(this string input, int length) { int index = 0; while (index < input.Length) { if (index + length < input.Length) yield return input.Substring(index, length); else yield return input.Substring(index); index += length; } } This takes a string, and it chops it up into a collection of strings that do not exceed the given length. This works well - however I'd like to go further. It chops words in half. I don't need it to understand anything complicated, I just want it to be able to chop a string off 'early' if cutting it at the length would be cutting in the middle of text (basically anything that isn't whitespace). However I suck at LINQ, so I was wondering if anyone had an idea on how to go about this. I know what I am trying to do, but I'm not sure how to approach it. So let's say I have the following text. This is a sample block of text that I would pass through the string splitter. I call this method SplitOnLength(6) I would get the following. This i s a sa mple b lock o f text that I would pass t hrough the s tring splitt er. I would rather it be smart enough to stop and look more like .. This is a sample // bad example, since the single word exceeds maximum length, but the length would be larger numbers in real scenarios, closer to 200. Can anyone help me?

  • PCRE (recursive) pattern that matches a string containing a correctly parenthesized substring. Why d

    - by Anton N. Petrov
    Well, there are other ways (hmmm... or rather working ways) to do it, but the question is why does this one fail? / \A # start of the string ( # group 1 (?: # group 2 [^()]* # something other than parentheses (greedy) | # or \( (?1) \) # parenthesized group 1 ) # -group 2 + # at least once (greedy) ) # -group 1 \Z # end of the string /x Fails to match a string with nested parentheses: "(())"

  • How to include and evaluate xhtml content represented as a String into a page using JSF?

    - by happycoder
    Hi! Im using JSF 1.2 and need to include xhtml content represented as a String in a bean. So, how can I get the content from a bean in xhtml but represented as a String and render it on the page? Here is an example: myPage.xhml ... xmlns:ui="http://java.sun.com/jsf/facelets" xmlns:h="http://java.sun.com/jsf/html" xmlns:a4j="http://richfaces.org/a4j" ... <h:panelGrid> <a4j:outputPanel ajaxRendered="true"> <ui:include src="#{myBean.someContent}" /> <!-- this doesnt work! --> </a4j:outputPanel> </h:panelGrid> ... MyBean.java ... class MyBean ... { private String someContent = "<h:panelGrid><h:outputText value=\"Name:\"/><h:inputText value=\"#{anotherBean.name}\" /></h:panelGrid>"; public String getSomeContent() { return someContent; } public void setSomeContent(String someContent) { this.someContent = someContent; } } i.e. in myPage.xhtml I want to read the someContent variable and include the content before page evaluation. The ui:include-tag nor the h:outputText escape="false" seems to work. /happycoder

  • Intelligent search and generation of Java code, preferrably using Python?

    - by Ipsquiggle
    Basically, I do lots of one-off code generation, large-scale refactorings, etc. etc. in Java. My tool language of choice is Python, but I'll take whatever solutions you can offer. Here is a simplified illustration of what I would like, in a pseudocode Generating an implementation for an interface search within my project: for each Interface as iName: write class(name=iName+"Impl", implements=iName) search within the body of iName: for each Method as mName: write method(name=mName, body="// TODO implement this...") Basically, the tool I'm searching for would allow me to: parse files according to their Java structure ("search for interfaces") search for words contextualized by language elements and types ("variables of type SomeClass", "doStuff() method calls on SomeClass instances") to run searches with structural context ("within the body of the current result") easily replace or generate code (with helpers to generate, as above, or functions for replacing, "rename the interface to Foo", "insert the line Blah.Blah()", etc.) The point is, I don't want to spend a lot of time writing these things, as they are usually throwaway. But sometimes I need something just a little smarter than what grep offers. It wouldn't be too hard to write up a simplistic version of this, but if I'm going to use something like this at all, I'd expect it to be robust. Any suggestions of a tool/library that will help me accomplish this?

  • Handling a button click in MVC, why is there a string parameter?

    - by SLC
    I'm following this awful textbook, going through the basics of create/edit/delete records. The delete bit has a confirm button, and it is handled like so: [AcceptVerbs(HttpVerbs.Post)] public ActionResult Delete(int id, string confirmButton) { It offers no explanation of why the button is passed as a string or how MVC interprets it. Can anyone help clarify what's going on here? The Create code has no such string being passed.

  • How do i change Object to String in a class which extends AsyncTask?

    - by Filip V.
    I'm learning from Google's Android developing tutorial and i came across a problem. On this link https://developer.android.com/training/basics/network-ops/connecting.html#AsyncTask it says to create a class that extends AsyncTask. So when i write the class it automatically implements the method as follows: private Object doInBackground(Object... args) {..} //it's fine but when i try writing just as it says in the tutorial: private String doInBackground(String... args) {..} //it gives an error and the error says: The method doInBackground(String...) of type MainActivity.DownloadWebpageText must override a superclass method. So how do i change Object to String without getting an error there?

  • JQuery Autocomplete Form Submission

    - by user1658370
    I have managed to implement the jQuery autocomplete plugin on my website but was wondering if it is possible to make the form auto-submit once the user selects an item from the search. I have the following set-up: HTML Form: <form class="quick_search" action="../include/search.php" method="post"> <input type="text" name="search" id="search" value="Search..."> </form> JavaScript: $().ready(function() { $("#search").autocomplete("../include/search.php", { width: 350, selectFirst: false }); }); I have also included the jQuery and Autoplugin scripts. The search.php file contains a list of the search options. At the moment, the search works correctly and I just need it to submit the form once an item is selected from the list that appears. I tried to use the onClick and onSelect options within the search field but neither of these worked correctly. Any help would be much appreciated (I don't really understand js)! Thanks.

  • How to make web service methods return string value in lines format?

    How to make web service methods return string value in lines format? My web service method looks like this [WebMethod] public string GetSomeLines() { System.Text.StringBuilder builder = new StringBuilder(); builder.AppendLine("Line1."); builder.AppendLine("Line2."); builder.AppendLine("Line3."); return builder.ToString(); } But when I get the result from web browser or from delphi/c# consumer it will be like this: Line1. Line2. Line3. While I expect to see: Line1. Line2. Line3. I know may be returning a StringBuilder or String Array is an option here but I want to know if there is a way to make this with string result. Thanks for your help.

  • Python - Find where in string regex match was found?

    - by nb
    I'm currently using regular expressions to search through RSS feeds to find if certain words and phrases are mentioned, and would then like to extract the text on either side of the match as well. For example: String = "This is an example sentence, it is for demonstration only" re.search("is", String) I'd like to know where the is was found so that I can extract and output something like this: 1 match found: "This is an example sentence" I know that it would be easy to do with splits, but I'd need to know what the index of first character of the match was in the string, which I don't know how to find

  • Parsing an XML string containing "&#x20;" (which must be preserved)

    - by Zoodor
    I have code that is passed a string containing XML. This XML may contain one or more instances of &#x20; (an entity reference for the blank space character). I have a requirement that these references should not be resolved (i.e. they should not be replaced with an actual space character). Is there any way for me to achieve this? Basically, given a string containing the XML: <pattern value="[A-Z0-9&#x20;]" /> I do not want it to be converted to: <pattern value="[A-Z0-9 ]" /> (What I am actually trying to achieve is to simply take an XML string and write it to a "pretty-printed" file. This is having the side-effect of resolving occurrences of &#x20; in the string to a single space character, which need to be preserved. The reason for this requirement is that the written XML document must conform to an externally-defined specification.) I have tried creating a sub-class of XmlTextReader to read from the XML string and overriding the ResolveEntity() method, but this isn't called. I have also tried assigning a custom XmlResolver.

  • How can I use SQL Server's full text search across multiple rows at once?

    - by Morbo
    I'm trying to improve the search functionality on my web forums. I've got a table of posts, and each post has (among other less interesting things): PostID, a unique ID for the individual post. ThreadID, an ID of the thread the post belongs to. There can be any number of posts per thread. Text, because a forum would be really boring without it. I want to write an efficient query that will search the threads in the forum for a series of words, and it should return a hit for any ThreadID for which there are posts that include all of the search words. For example, let's say that thread 9 has post 1001 with the word "cat" in it, and also post 1027 with the word "hat" in it. I want a search for cat hat to return a hit for thread 9. This seems like a straightforward requirement, but I don't know of an efficient way to do it. Using the regular FREETEXT and CONTAINS capabilities for N'cat AND hat' won't return any hits in the above example because the words exist in different posts, even though those posts are in the same thread. (As far as I can tell, when using CREATE FULLTEXT INDEX I have to give it my index on the primary key PostID, and can't tell it to index all posts with the same ThreadID together.) The solution that I currently have in place works, but sucks: maintain a separate table that contains the entire concatenated post text of every thread, and make a full text index on THAT. I'm looking for a solution that doesn't require me to keep a duplicate copy of the entire text of every thread in my forums. Any ideas? Am I missing something obvious?

  • What's the most efficient way to combine two List(Of String)?

    Let's say I've got: Dim los1 as New List(Of String) los1.Add("Some value") Dim los2 as New List(Of String) los2.Add("More values") What would be the most efficient way to combine the two into a single List(Of String)? Edit: While I'm loving the solutions everyone has provided so far, I probably should also mention I'm stuck using the .NET 2.0 framework. Any other suggestions?
