  • C# wpf: Need to add mouseclick event to certain text within a textbox

    - by Michael
    I have a textbox with a paragraph of information. There are certain words in the paragraph that i want the user to be able to click on, and when clicked, a different textbox is populated with more information. I know that you can have the event for the whole textbox, but that isn't want i want. I only want to call that event when certain words within the box are clicked.

  • Get Item from Collection by unique ID

    - by David Murdoch
    I have a collection of Contacts that inherits from CollectionBase: public class ContactCollection : CollectionBase{ //... } each contact in the collection has a unique ID: public class Contact{ public int ContactID{ get; private set; } //... } I think what I would like to do is something like the following: // get the contact by their unique [Contact]ID Contact myPerson = Contact.GetContactById(15); // get all contacts for the customer ContactCollection contacts = customer.GetContacts(); // replaces the contact in the collection with the // myPerson contact with the same ContactID. contacts.ReplaceAt(myPerson); // saves the changes to the contacts and the customer // customer.Save(); There is probably a better way...if so, please suggest it.

  • c# finding matching words in table column using Linq2Sql

    - by David Liddle
    I am trying to use Linq2Sql to return all rows that contain values from a list of strings. The linq2sql class object has a string property that contains words separated by spaces. public class MyObject { public string MyProperty { get; set; } } Example MyProperty values are: MyObject1.MyProperty = "text1 text2 text3 text4" MyObject2.MyProperty = "text2" For example, using a string collection, I pass the below list var list = new List<>() { "text2", "text4" } This would return both items in my example above as they both contain "text2" value. I attempted the following using the below code however, because of my extension method the Linq2Sql cannot be evaluated. public static IQueryable<MyObject> WithProperty(this IQueryable<MyProperty> qry, IList<string> p) { return from t in qry where t.MyProperty.Contains(p, ' ') select t; } I also wrote an extension method public static bool Contains(this string str, IList<string> list, char seperator) { if (String.IsNullOrEmpty(str) || list == null) return false; var splitStr = str.Split(new char[] { seperator }, StringSplitOptions.RemoveEmptyEntries); foreach (string s in splitStr) foreach (string l in list) if (String.Compare(s, l, true) == 0) return true; return false; } Any help or ideas on how I could achieve this?

  • Cygwin environment variable case

    - by Michael
    For some reason on one pc, when variable names are going from batch file to Cygwin environment, they are capitalizing. On other the case stay intact. @set aa=bb %BASH% --login -c "set" so the output in one case will show AA=bb in other case aa=bb How to control the case of the exported variables?

  • How to copy a variable in JavaScript?

    - by Michael Stum
    I have this JavaScript code: for (var idx in data) { var row = $("<tr></tr>"); row.click(function() { alert(idx); }); table.append(row); } So I'm looking through an array, dynamically creating rows (the part where I create the cells is omitted as it's not important). Important is that I create a new function which encloses the idx variable. However, idx is only a reference, so at the end of the loop, all rows have the same function and all alert the same value. One way I solve this at the moment is by doing this: function GetRowClickFunction(idx){ return function() { alert(idx); } } and in the calling code I call row.click(GetRowClickFunction(idx)); This works, but is somewhat ugly. I wonder if there is a better way to just copy the current value of idx inside the loop? While the problem itself is not jQuery specific (it's related to JavaScript closures/scope), I use jQuery and hence a jQuery-only solution is okay if it works.

  • Changing type of object in a conditional

    - by David Doria
    I'm having a bit of trouble with dynamic_casting. I need to determine at runtime the type of an object. Here is a demo: include include class PersonClass { public: std::string Name; virtual void test(){}; //it is annoying that this has to be here... }; class LawyerClass : public PersonClass { public: void GoToCourt(){}; }; class DoctorClass : public PersonClass { public: void GoToSurgery(){}; }; int main(int argc, char *argv[]) { PersonClass* person = new PersonClass; if(true) { person = dynamic_cast(person); } else { person = dynamic_cast(person); } person-GoToCourt(); return 0; } I would like to do the above. The only legal way I found to do it is to define all of the objects before hand: PersonClass* person = new PersonClass; LawyerClass* lawyer; DoctorClass* doctor; if(true) { lawyer = dynamic_cast(person); } else { doctor = dynamic_cast(person); } if(true) { lawyer-GoToCourt(); } The main problem with this (besides having to define a bunch of objects that won't be use) is that I have to change the name of the 'person' variable. Is there a better way? (I am not allowed to change any of the classes (Person, Lawyer, or Doctor) because they are part of a library that people who will use my code have and won't want to change). Thanks, Dave

  • Should I use interface builder or not?

    - by Michael Waterfall
    I'd like to know more about the pros and cons of using interface builder when developing iPhone/iPad apps. I've written a fairly complex and customized app that's on the app store right now, but all of the interfaces are hand coded as they are fairly complex. I've customised the navigation and tab bars with backgrounds, table view cells are manually drawn for speed, and some views are complex and scalable with many subviews. I'm pondering whether or not to start using interface builder but I'm not sure to what extent I'll use it and whether it's worth it at all. Is it quicker? Can things still be easily customised? Any advice would be most welcome!

  • Getting specific values with regex

    - by David
    I need to knowingly isolate each row of the vCard and get its value. For instance, I want to get "5555" from X-CUSTOMFIELD. So far, my thoughts are: "X-CUSTOMFIELD;\d+" I have been looking at some tutorials and I am a little confused with what function to use? What would my regex above return? Would it give me the whole line or just the numerical part (5555)? I was thinking I i get the whole row, I can use substring to get the digits? BEGIN:VCARD VERSION:2.1 N:Last;First; FN:First Last TEL;HOME;VOICE:111111 TEL;MOBILE;VOICE:222222 X-CUSTOMFIELD;5555 END:VCARD

  • How do I sync iPad Notes without Mail?

    - by Michael
    The default Notes app on the iPad is fine for my note taking needs. I see how it syncs through iTunes to Mail, but if one doesn't use Mail for e-mail management, is there any other way to sync and view the iPad notes on the desktop? (We use Eudora for mail management, and Apple's Mail is not great if all you want to do is view your notes with it.)

  • Creating an XmlNode/XmlElement in C# without an XmlDocument?

    - by Michael Stum
    I have a simple class that essentially just holds some values. I have overridden the ToString() method to return a nice string representation. Now, I want to create a ToXml() method, that will return something like this: <Song> <Artist>Bla</Artist> <Title>Foo</Title> </Song> Of course, I could just use a StringBuilder here, but I would like to return an XmlNode or XmlElement, to be used with XmlDocument.AppendChild. I do not seem to be able to create an XmlElement other than calling XmlDocument.CreateElement, so I wonder if I have just overlooked anything, or if I really either have to pass in either a XmlDocument or ref XmlElement to work with, or have the function return a String that contains the XML I want?

  • php, extract data from a non-standard xml document

    - by Michael
    I have some kind xml content I need to extract the information and store it into database <xml file="136000000-136100000"> <Id>136000000</Id> <Name>Sem Serxy</Na me> <Email>[email protected]</Email> <DateRegistration>10/13/2010 1:49:30 AM</DateRegistration> </xml> <xml file="136000000-136100000"> <Id>136000001</Id> <Name>God Deckor</Name> <Email>[email protected]</Email> If I try simple xml load is not working as the document doesn't seem to be valid xml. I can use regex to extract the info with preg_match_all but I feel this is not the right way as the data is already well structured. Any other method ?

  • Cakephp beforeFind() - How do I add a JOIN condition AFTER the belongsTo association is added?

    - by michael
    I'm in Model-beforeFind($queryData), trying to add a JOIN condition to the queryData on a model which has belongsTo associations. Unfortunately, the new JOIN references a table in the belongsTo association, so it must appear AFTER the belongsTo in the query. Here is my Tagged-belongsTo association: app\plugins\tags\models\tagged.php (line 192) Array ( [Tag] => Array ( [className] => Tag [foreignKey] => tag_id [conditions] => [fields] => [order] => [counterCache] => ) [Group] => Array ( [className] => Group [foreignKey] => foreign_key [conditions] => Array ( [Tagged.model] => Group ) [fields] => [order] => [counterCache] => ) ) Here is the JOIN added in Tagged-beforeFind(), notice that the belongsTo joins have not yet been added: app\plugins\tags\models\tagged.php (line 194) Array ( [conditions] => Array ( [Tag.keyname] => europe ) [fields] => Array ( [0] => DISTINCT Group.* [1] => GroupPermission.* ) [joins] => Array ( [0] => Array ( [table] => permissions [alias] => GroupPermission [foreignKey] => [type] => INNER [conditions] => Array ( [GroupPermission.model] => Group [0] => GroupPermission.foreignId = Group.id [or] => Array ( ... ) ) ) ) [limit] => [offset] => [order] => Array ( [0] => ) [page] => 1 [group] => [callbacks] => 1 [by] => europe [model] => Group ) When I check the output, it fails with "1054: Unknown column 'Group.id' in 'on clause'" because the Permissions join appeared BEFORE the Groups join. SELECT DISTINCT `Group`.*, `GroupPermission`.* FROM `tagged` AS `Tagged` INNER JOIN permissions AS `GroupPermission` ON (`GroupPermission`.`model` = 'Group' AND `GroupPermission`.`foreignId` = `Group`.`id` AND (...)) LEFT JOIN `tags` AS `Tag` ON (`Tagged`.`tag_id` = `Tag`.`id`) LEFT JOIN `groups` AS `Group` ON (`Tagged`.`foreign_key` = `Group`.`id` AND `Tagged`.`model` = 'Group') WHERE `Tag`.`keyname` = 'europe' But this SQL (with Permissions joined moved to the end) works fine: SELECT DISTINCT `Group`.*, `GroupPermission`.* FROM `tagged` AS `Tagged` LEFT JOIN `tags` AS `Tag` ON (`Tagged`.`tag_id` = `Tag`.`id`) LEFT JOIN `groups` AS `Group` ON (`Tagged`.`foreign_key` = `Group`.`id` AND `Tagged`.`model` = 'Group') INNER JOIN permissions AS `GroupPermission` ON (`GroupPermission`.`model` = 'Group' AND `GroupPermission`.`foreignId` = `Group`.`id` AND (...)) WHERE `Tag`.`keyname` = 'europe' How do I add my join in beforeFind() after the belongsTo join?

  • c# Lambda Expression built with LinqKit does not compile

  • C Question: How to store data inside the executable file

    - by michael
    Hello all, complete newbie here, I need to find a way to store 250 KB of plain text numbers inside my program's executable file. Usually, I would put the data in a separate file and let the program read it while it is running, but that's not an option here. Instead, the program and the data need to be in one executable file. I have absolutely no idea how to do it (except writing 250.000 #defines :-) and I'd appreciate any suggestions. Thank you very much!

  • Is it possible to tie nested generics?

    - by Michael Deardeuff
    Is it possible to tie nested generics/captures together? I often have the problem of having a Map lookup of class to genericized item of said class. In concrete terms I want something like this (no, T is not declared anywhere). private Map<Class<T>, ServiceLoader<T>> loaders = Maps.newHashMap(); In short, I want loaders.put/get to have semantics something like these: <T> ServiceLoader<T> get(Class<T> klass) {...} <T> void put(Class<T> klass, ServiceLoader<T> loader) {...} Is the following the best I can do? Do I have to live with the inevitable @SuppressWarnings("unchecked") somewhere down the line? private Map<Class<?>, ServiceLoader<?>> loaders = Maps.newHashMap();

  • Finding mySQL duplicates, then merging data

    - by Michael Pasqualone
    I have a mySQL database with a tad under 2 million rows. The database is non-interactive, so efficiency isn't key. The (simplified) structure I have is: `id` int(11) NOT NULL auto_increment `category` varchar(64) NOT NULL `productListing` varchar(256) NOT NULL Now the problem I would like to solve is, I want to find duplicates on productListing field, merge the data on the category field into a single result - deleting the duplicates. So given the following data: +----+-----------+---------------------------+ | id | category | productListing | +----+-----------+---------------------------+ | 1 | Category1 | productGroup1 | | 2 | Category2 | productGroup1 | | 3 | Category3 | anotherGroup9 | +----+-----------+---------------------------+ What I want to end up is with: +----+----------------------+---------------------------+ | id | category | productListing | +----+----------------------+---------------------------+ | 1 | Category1,Category2 | productGroup1 | | 3 | Category3 | anotherGroup9 | +----+----------------------+---------------------------+ What's the most efficient way to do this either in pure mySQL query or php?

  • Is there a Java unit-test framework that auto-tests getters and setters?

    - by Michael Easter
    There is a well-known debate in Java (and other communities, I'm sure) whether or not trivial getter/setter methods should be tested. Usually, this is with respect to code coverage. Let's agree that this is an open debate, and not try to answer it here. There have been several blog posts on using Java reflection to auto-test such methods. Does any framework (e.g. jUnit) provide such a feature? e.g. An annotation that says "this test T should auto-test all the getters/setters on class C, because I assert that they are standard". It seems to me that it would add value, and if it were configurable, the 'debate' would be left as an option to the user.
