  • Is there a way to split a widescreen monitor in to two or more virtual monitors?

    - by Mike Thompson
    Like most developers I have grown to love dual monitors. I won't go into all the reasons for their goodness; just take it as a given. However, they are not perfect. You can never seem to line them up "just right". You always end up with the monitors at slight funny angles. And of course the bezel always gets in the way. And this is with identical monitors. The problem is much worse with different monitors -- VMWare's multi monitor feature won't even work with monitors of differnt resolutions. When you use multiple monnitors, one of them becomes your primary monitor of focus. Your focus may flip from one monitor to the other, but at any point in time you are usually focusing on only one monitor. There are exceptions to this (WinDiff, Excel), but this is generally the case. I suggest that having a single large monitor with all the benefits of multiple smaller monitors would be a better solution. Wide screen monitors are fantastic, but it is hard to use all the space efficiently. If you are writing code you are generally working on the left-hand side of the window. If you maximize an editor on a wide-screen monitor the right-hand side of the window will be a sea of white. Programs like WinSplit Revolution will help to organise your windows, but this is really just addressing the symptom, not the problem. Even with WinSplit Revolution, when you maximise a window it will take up the whole screen. You can't lock a window into a specific section of the screen. This is where virtual monitors comes in. What would be really nice is a video driver that sits on top of the existing driver, but allows a single monitor to be virtualised into multiple monitors. Control Panel would see your single physical monitor as two or more virtual monitors. The software could even support a virtual bezel to emphasise what is happening, or you could opt for seamless mode. Programs like WinSplit Revolution and UltraMon would still work. This virtual video driver would allow you to slice & dice your physical monitor into as many virtual monitors as you want. Does anybody know if such software exists? If not, are there any budding Windows display driver guru's out there willing to take up the challenge? I am not after the myriad of virtual desktop/window manager programs that are available. I get frustrated with these programs. They seem good at first but they usually have some strange behaviour and don't work well with other programs (such as WinSplit Revolution). I want the real thing!

  • UTF-8 to ISO-8859-1 mapping / lossless conversion libraries in Java

    - by Pawel Krupinski
    I need to perform a conversion of characters from UTF-8 to ISO-8859-1 in Java without losing for example all of the UTF-8 specific punctuation. Ideally would like these to be converted to equivalents in ISO (e.g. there are probably 5 different single quotes in UTF-8 and would like them all converted to ISO single quote character). String.getBytes("ISO-8859-1") just won't do the trick in this case as it will lose the UTF-8-specific chars. Do you know of any ready mappings or libraries in Java that would map UTF-8 specific characters to ISO?

  • XSLT: How do I trigger a template when there is no input file?

    - by Ben Blank
    I'm creating a template which produces output based on a single string, passed via parameter, and does not use an input XML document. xsltproc seems to happily run with a single parameter specifying the stylesheet, but I don't see a way to trigger a template without an input file (no parameter to xsltproc to run a named template, for example). I'd like to be able to run: xsltproc --stringparam bar baz foo.xsl But I'm currently having to run, with the "main" template matching "/": echo '<xml/>' | xsltproc --stringparam bar baz foo.xsl - How can I get this to work? I'm sure I've seen other templates in the past which were meant to be run without an input document, but I don't remember how they worked or where to find them again. :-)

  • How can I capture multiple matches from the same Perl regex?

    - by Sho Minamimoto
    I'm trying to parse a single string and get multiple chunks of data out from the same string with the same regex conditions. I'm parsing a single HTML doc that is static (For an undisclosed reason, I can't use an HTML parser to do the job.) I have an expression that looks like: $string =~ /\<img\ssrc\="(.*)"/; and I want to get the value of $1. However, in the one string, there are many img tags like this, so I need something like an array returned (@1?) is this possible?

  • merging arrays of hashes

    - by Ben
    I have two arrays of hashes. Array1 => [{attribute_1 = A, attribute_2 = B}, {attribute_1 = A, attribute_2 = B}] Array2 => [{attribute_3 = C, attribute_2 = D}, {attribute_3 = C, attribute_4 = D}] Each hash in the array is holding attributes for an object. In the above example, there are two objects that I'm working with. There are two attributes in each array for each object How do I merge the two arrays? I am trying to get a single array (there is no way to get a single array from the start because I have to make two different API calls to get these attributes). DesiredArray => [{attribute_1 = A, attribute_2 = B, attribute_3 = C, attribute_2 = D}, {attribute_1 = A, attribute_2 = B, attribute_3 = C, attribute_2 = D}] I've tried a couple things, including the iteration methods and the merge method, but I've been unable to get the array I need.

  • using Mutex causing application to hang on Win XP X64

    - by Mohsan
    hi. I used the following code to verify the single instance of application. On Win XP X86 it is working fine, but on X64 after 3 to 4 minutes System generates StackOverflowException and causes the application to hang. after removing this check application is working fine.. Please tell me what should be the reason. code is static void Main() { bool instanceCountOne = false; using (Mutex mtex = new Mutex(true, "AppName", out instanceCountOne)) { if (instanceCountOne) { #if (DEBUG) RunInDebugMode(); #else RunInReleaseMode(); #endif mtex.ReleaseMutex(); } else { MessageBox.Show( "An application instance is already running", "App Name", MessageBoxButtons.OK, MessageBoxIcon.Information); } } } it crashes when single instance of application is running.

  • How should I add multi language support to my web app across PHP, JS and Template Files?

    - by Camsoft
    I'm building a website that needs to support different language translations. I have strings in PHP, JavaScript and Smarty Template files that need to translated. I want to use something like PHP's gettext() function and have a single language file for each locale. This is easy when the translatable strings are in the PHP files but I also have text in the Smarty Templates and JavaScript files that also need to be translated. I really want one single file that holds all the translatable strings. What is the best way to achieve this?

  • What is .htaccess RewriteRule best practice?

    - by Pablo
    Is it better to have a single RewriteRule with a bunch of RegEx or multiples Rules with fewer RegEx for the server to query? Will there be any performance differences? Heres is an example a single rule with almost all RegEx groups as optional: RewriteRule ^gallery/?([\w]+)?/?([\w]+)?/?([\d]+)?/?([\w]+)/?$ /gallery.php?$1=$2&start=$3&by=$4 [NC] Here are some of the rules lists that would replace the one above: RewriteRule ^gallery/category/([\w]+)/$ /gallery.php?category=$1& [NC] RewriteRule ^gallery/category/([\w]+)/([\d]+)/$ /gallery.php?category=$1&start=$2 [NC] RewriteRule ^gallery/category/([\w]+)/([\d]+)/([\w]+)/$ /gallery.php?category=$1&start=$2&by=$3 [NC] ... RewriteRule ^gallery/tag/([\w]+)/$ /gallery.php?category=$1& [NC] RewriteRule ^gallery/tag/([\w]+)/([\d]+)/$ /gallery.php?category=$1&start=$2 [NC] RewriteRule ^gallery/tag/([\w]+)/([\d]+)/([\w]+)/$ /gallery.php?category=$1&start=$2&by=$3 [NC] ... I'll be glad to hear your options or personal experiences.

  • AVG time spent on multiple rows SQL-server?

Would like to calculate the average time spent per IP. in a single row Know you can do something like this: SELECT CAST(AVG(CAST(MyTable.MyDateTimeFinish - MyTable.MyDateTimeStart AS float)) AS datetime) But how on earth do I find the first and last entry of my unique IP row so I can have a start and finish time? I'M stuck. Would like to calculate the average time spent per IP. in a single row

  • SelfReferenceProperty vs. ListProperty Google App Engine

    - by John
    Hi All, I am experimenting with the Google App Engine and have a question. For the sake of simplicity, let's say my app is modeling a computer network (a fairly large corporate network with 10,000 nodes). I am trying to model my Node class as follows: class Node(db.Model): name = db.StringProperty() neighbors = db.SelfReferenceProperty() Let's suppose, for a minute, that I cannot use a ListProperty(). Based on my experiments to date, I can assign only a single entity to 'neighbors' - and I cannot use the "virtual" collection (node_set) to access the list of Node neighbors. So... my questions are: Does SelfReferenceProperty limit you to a single entity that you can reference? If I instead use a ListProperty, I believe I am limited to 5,000 keys, which I need to exceed. Thoughts? Thanks, John

  • Can't check more than one RadioButton across multiple items in a Treeview

    - by Mike Johnston
    I’m using a TreeView control to present a list of Questions. Using the Prism.DataTemplateSelector, I'm loading a View (.xaml file) that represents a single Question into each node in the TreeView. In the View for that question is a ListBox containing RadioButtons (one for each item in a Picklist object that the ListBox is bound to). The radio buttons work as expected for the question, but when I check a RadioButton on another node/question in the TreeView, the check for the button in the Question I was editing before disappears. In other words, I'm only able to check one RadioButton in the whole list of Questions/Items bound to the containing TreeView. How do I group the RadioButtons in the ListBox to the scope of the single question instead of all the questions in the TreeView.

Why mails are not delivered ? And is it possible to view the subject for the all mail status instead of message id? I mean to review the status of the single mail. We are using Sawmill analyzer now. But the management is not satisfied with the report from the sawmaill, since its missing single message status and subject.

  • Create fulltext index on a VIEW

    - by kylex
    Is it possible to create a full text index on a VIEW? If so, given two columns column1 and column2 on a VIEW, what is the SQL to get this done? The reason I'd like to do this is I have two very large tables, where I need to do a FULLTEXT search of a single column on each table and combine the results. The results need to be ordered as a single unit. Suggestions? EDIT: This was my attempt at creating a UNION and ordering by each statements scoring. (SELECT a_name AS name, MATCH(a_name) AGAINST('$keyword') as ascore FROM a WHERE MATCH a_name AGAINST('$keyword')) UNION (SELECT s_name AS name,MATCH(s_name) AGAINST('$keyword') as sscore FROM s WHERE MATCH s_name AGAINST('$keyword')) ORDER BY (ascore + sscore) ASC sscore was not recognized.

  • acts_as_solr returns all rows in the database when using the model as search query

    - by chris Chan
    In our application we're using acts_as_solr for search. Everything seems to be running smoothly except for the fact that using the model name as the search query returns every single row in the table. For example, let's say we have a users table. We specify acts_as_solr in our model to search the fields first name, last name and handle acts_as_solr :fields = [:handle, :lname, :fname]. When you use "user" as the search term it returns every single user in the system, or every row in the database as a result. Has anyone else run into this?

    Hi, I have the following models: class User < ActiveRecord::Base has_many :results, :dependent => :destroy has_many :participants, :dependent => :destroy has_many :courses, :through => :participants end class Course < ActiveRecord::Base has_many :tests, :dependent => :destroy has_many :participants, :dependent => :destroy has_many :users, :through => :participants end class Result < ActiveRecord::Base belongs_to :test belongs_to :user end class Test < ActiveRecord::Base belongs_to :course has_many :results, :dependent => :destroy end The Idea is that a user has_and_belongs_to_many courses, the course has_many tests, and every test has_and_belongs_to_many users (results). So what is the best query to select every Result from a single Course (not test), and also the query to select every Result from a single Course, but from one user. Thanks!

  • Javascript calls to an Ajax WebMethod. How to get multiple output params returned?

    OK, I know how to call a simple old fashion asmx webservice webthod that returns a single value as a function return result. But what if I want to return multiple output params? My current approach is to separate the params by a dividing character and parse them on teh client. Is there a better way. Here's how I return a single function result. How do I return multiple output values? <asp:ScriptManager ID="ScriptManager1" runat="server"> <Services> <asp:ServiceReference Path="WebService.asmx" /> </Services> function CallHelloWebMethod() { WebService.Hello(OnComplete1, OnTimeOut, OnError); } function OnComplete1(arg) { alert(arg); } function OnTimeOut(arg) { } <WebMethod()> Public Function Hello(ByVal x As String) As String Return "Hello " & x End Function

  • AuthLogic perishable_token resets on every request

    - by go minimal
    In my User model I have: acts_as_authentic do |c| c.perishable_token_valid_for = 30.minutes end In my Application Controller I have the standard boilerplate code: def current_user_session return @current_user_session if defined?(@current_user_session) @current_user_session = UserSession.find end def current_user return @current_user if defined?(@current_user) @current_user = current_user_session && current_user_session.record end Now in my view I need to see if a user is logged in: <% if current_user %> Sign Out <% else %> Sign In <% end %> On every single request, current_user is being called, and that causes a SELECT call to be made to the database to find the user, then an UPDATE call that updates the last_request_at and perishable_token even though I set perishable_token_valid_for = 30.minutes. Does anyone have a better way to see if a user is logged in without causing a SELECT and UPDATE on every single page of my app. Does anyone know why the perishable token keeps updating even if I set it to be valid for 30 minutes???

  • noindex, follow on list views?

    - by Fabrizio
    On one of our client's website we have lot's of list views with links to detail views. (Image a blog with the posts overview and the single pages). The detail views don't change, but the list views will change when new items come up. The pages displaying the list view don't contain any other valuable content. So my question is: Does it make sense to define meta "noindex, follow" on the list view pages (and of course "index, follow" on the detail views) to prevent search engines to point to the list views when the keyword is found in the title or teaser of the list view. By the time the visitor clicks on the list view search result it might have changed and the content is not visible anymore, whereas if he goes directly to the single view he will definitly find what he was searching for? Related question: The startpage also contains mainly a list view. Is it a bad idea to have the start page not indexed? Any SEO gurus here? :) Thanks, Fabrizio.

  • Why do Pascal control structures appear to be inconsistent?

    - by 70Mike
    Most Pascal control structures make sense to me, like: for ... do {statement}; if (condition) then {statement}; while (condition) do {statement}; where the {statement} is either a single statement, or a begin ... end block. I have a problem with: repeat {statement-list} until (expression); try {statement-list} except {statement-list} end; Wouldn't it be better that repeat and try have the same general structure, accepting only a single statement or a begin ... end block, instead of having a statement-list that's not formally blocked with a begin and an end?

  • MongoDB RSS Feed Entries, Embed the Entries in the Feed Object?

    - by Patrick Klingemann
    I am saving a reference to an RSS Feed in MongoDB, each Feed has an ever growing list of Entries. As I'm designing my schema, I'm concerned about this statement from the MongoDB Schema Design - Embed vs. Reference Documentation: If the amount of data to embed is huge (many megabytes), you may read the limit on size of a single object. This will surely happen if I understand the statement correctly. So the question is, I am correct to assume that I should not embed the Feed Entries within a Feed because I'll eventually reach the limit on size of a single object?

  • NHibernate Named Query Parameter Numbering @p1 @p2 etc

    - by IanT8
    A colleague recently ran into a problem where he was passing in a single date parameter to a named query. In the query, the parameter was being used twice, once in an expression and once in a GROUP BY clause. Much to our surprise, we discovered that NHibernate used two variables and sent the single named parameter in twice, as @p1 and @p2. This behaviour caused SQL to fail the query, with the usual "a column in the select clause is not in the group by clause" (I paraphrase ofcourse). Is this behaviour normal? Can it be changed? Seems to me that if you have a parameter name like :startDate, NHibernate only needs to pass in @p1 no matter how many times you might refer to :startDate in the query. Any comments? The problem was worked around by using another sub-query to overcome the SQL parsing error.
