  • Cancel draggable dragging

    - by JohnM2
    I have a draggable (jquery-ui) element. I subscribe to it's 'drag' event. How can I cancel current draggig based on some constraints? So I want to constraint possible moves of this draggable element, but it is more custom then only based on axis or parent (containment). How can I do that?

  • Multiple accordion panes open

    - by Kevin
    We are using a jquery accordion on our site : http://www.racedayworld.com It basically lists events under each month... Apparently people are finding difficulties knowing how it really works and they don't see at first glance that there are more events under each month (that you click to expand) So I was thinking about opening two at a time (the current month and the next) .. but I'm not sure how to enable both to be open at once ... any ideas?

  • how to detect sql server timeout from .NET application without using catch Exception

    - by haditeo
    Hi, In my current application, i am performing an update by invoking T-SQL Update command. The problem is when the same record is locked by other users at that time. At .NET application, the application will wait until SQL Server timeout, then it will throw the SqlException timeout. Is it possible to perform a check first whether a particular record is locked by other process rather than catching the exception ? Thanks, hadi teo Update : The SQL Server version used are 2000 and 2008

  • What's the best Scala build system?

    - by gatoatigrado
    I've seen questions about IDE's here -- Which is the best IDE for Scala development? and What is the current state of tooling for Scala?, but I've had mixed experiences with IDEs. Right now, I'm using the Eclipse IDE with the automatic workspace refresh option, and KDE 4's Kate as my text editor. Here are some of the problems I'd like to solve: use my own editor IDEs are really geared at everyone using their components. I like Kate better, but the refresh system is very annoying (it doesn't use inotify, rather, maybe a 10s polling interval). The reason I don't use the built-in text editor is because broken auto-complete functionalities cause the IDE to hang for maybe 10s. rebuild only modified files The Eclipse build system is broken. It doesn't know when to rebuild classes. I find myself almost half of the time going to project-clean. Worse, it seems even after it has finished building my project, a few minutes later it will pop up with some bizarre error (edit - these errors appear to be things that were previously solved with a project clean, but then come back up...). Finally, setting "Preferences / Continue launch if project contains errors" to "prompt" seems to have no effect for Scala projects (i.e. it always launches even if there are errors). build customization I can use the "nightly" release, but I'll want to modify and use my own Scala builds, not the compiler that's built into the IDE's plugin. It would also be nice to pass [e.g.] -Xprint:jvm to the compiler (to print out lowered code). fast compiling Though Eclipse doesn't always build right, it does seem snappy -- even more so than fsc. I looked at Ant and Maven, though haven't employed either yet (I'll also need to spend time solving #3 and #4). I wanted to see if anyone has other suggestions before I spend time getting a suboptimal build system working. Thanks in advance! UPDATE - I'm now using Maven, passing a project as a compiler plugin to it. It seems fast enough; I'm not sure what kind of jar caching Maven does. A current repository for Scala 2.8.0 is available [link]. The archetypes are very cool, and cross-platform support seems very good. However, about compile issues, I'm not sure if fsc is actually fixed, or my project is stable enough (e.g. class names aren't changing) -- running it manually doesn't bother me as much. If you'd like to see an example, feel free to browse the pom.xml files I'm using [github]. UPDATE 2 - from benchmarks I've seen, Daniel Spiewak is right that buildr's faster than Maven (and, if one is doing incremental changes, Maven's 10 second latency gets annoying), so if one can craft a compatible build file, then it's probably worth it...

  • When does Visual Studio call target AfterBuild & BeforeBuild? And how is it handled when these targe

    - by Nam Gi VU
    Hi Fiburt, Today I meet a similar problem and it reminds me about this thread. In Visual Studio, if we open the .csproj file, we see that they tell us to uncomment the two targets AfterBuild and BeforeBuild so as to execute them after and before the build of the current project accordingly. My questions are: Where are these two targets called in Visual Studio? And how is it handled if the targets are not defined (be commented out) ?

  • Advice and resources for Apple iOS 4 development

    - by mlambie
    I'm looking for resources, screencasts, books, courses, sites and the like to assist with learning Objective-C with the intention of developing applications for Apple's iOS 4. My development team has access to Apple's development program, and is largely coming from a similar background: they're Comp Sci graduates that have experience with Ruby and web languages, but haven't written any C since university. Considering Apple's announcement regarding limited programming language support for developers, what's the current best avenue for learning Objective-C with the desire for developing iPad and iPhone applications?

  • Flex: Using NumericStepper as an itemEditor in a DataGrid

    - by AlexH
    I am trying to make one field in a datagrid editable with a numeric stepper. My current attempts look like they are working, but the dataProvider is not actually being changed. Based on what I have read in a billion different places, the syntax should be < mx:DataGridColumn dataField="a" itemRenderer="mx.controls.NumericStepper" rendererIsEditor="true" editorDataField="value" / > I have tried several variations on this theme, and nothing seems to work. What am I missing?

  • Optimize date query for large child tables: GiST or GIN?

    - by Dave Jarvis
    Problem 72 child tables, each having a year index and a station index, are defined as follows: CREATE TABLE climate.measurement_12_013 ( -- Inherited from table climate.measurement_12_013: id bigint NOT NULL DEFAULT nextval('climate.measurement_id_seq'::regclass), -- Inherited from table climate.measurement_12_013: station_id integer NOT NULL, -- Inherited from table climate.measurement_12_013: taken date NOT NULL, -- Inherited from table climate.measurement_12_013: amount numeric(8,2) NOT NULL, -- Inherited from table climate.measurement_12_013: category_id smallint NOT NULL, -- Inherited from table climate.measurement_12_013: flag character varying(1) NOT NULL DEFAULT ' '::character varying, CONSTRAINT measurement_12_013_category_id_check CHECK (category_id = 7), CONSTRAINT measurement_12_013_taken_check CHECK (date_part('month'::text, taken)::integer = 12) ) INHERITS (climate.measurement) CREATE INDEX measurement_12_013_s_idx ON climate.measurement_12_013 USING btree (station_id); CREATE INDEX measurement_12_013_y_idx ON climate.measurement_12_013 USING btree (date_part('year'::text, taken)); (Foreign key constraints to be added later.) The following query runs abysmally slow due to a full table scan: SELECT count(1) AS measurements, avg(m.amount) AS amount FROM climate.measurement m WHERE m.station_id IN ( SELECT s.id FROM climate.station s, climate.city c WHERE -- For one city ... -- c.id = 5182 AND -- Where stations are within an elevation range ... -- s.elevation BETWEEN 0 AND 3000 AND 6371.009 * SQRT( POW(RADIANS(c.latitude_decimal - s.latitude_decimal), 2) + (COS(RADIANS(c.latitude_decimal + s.latitude_decimal) / 2) * POW(RADIANS(c.longitude_decimal - s.longitude_decimal), 2)) ) <= 50 ) AND -- -- Begin extracting the data from the database. -- -- The data before 1900 is shaky; insufficient after 2009. -- extract( YEAR FROM m.taken ) BETWEEN 1900 AND 2009 AND -- Whittled down by category ... -- m.category_id = 1 AND m.taken BETWEEN -- Start date. (extract( YEAR FROM m.taken )||'-01-01')::date AND -- End date. Calculated by checking to see if the end date wraps -- into the next year. If it does, then add 1 to the current year. -- (cast(extract( YEAR FROM m.taken ) + greatest( -1 * sign( (extract( YEAR FROM m.taken )||'-12-31')::date - (extract( YEAR FROM m.taken )||'-01-01')::date ), 0 ) AS text)||'-12-31')::date GROUP BY extract( YEAR FROM m.taken ) The sluggishness comes from this part of the query: m.taken BETWEEN /* Start date. */ (extract( YEAR FROM m.taken )||'-01-01')::date AND /* End date. Calculated by checking to see if the end date wraps into the next year. If it does, then add 1 to the current year. */ (cast(extract( YEAR FROM m.taken ) + greatest( -1 * sign( (extract( YEAR FROM m.taken )||'-12-31')::date - (extract( YEAR FROM m.taken )||'-01-01')::date ), 0 ) AS text)||'-12-31')::date The HashAggregate from the plan shows a cost of 10006220141.11, which is, I suspect, on the astronomically huge side. There is a full table scan on the measurement table (itself having neither data nor indexes) being performed. The table aggregates 237 million rows from its child tables. Question What is the proper way to index the dates to avoid full table scans? Options I have considered: GIN GiST Rewrite the WHERE clause Separate year_taken, month_taken, and day_taken columns to the tables What are your thoughts? Thank you!

  • Security for ASP.NET Diagnostics page

    - by Moe Sisko
    I'm thinking of creating a diagnostics page for an ASP.NET app, which would be mostly intended for admin use to get more information about the application for diagnosing problems. Examples of the info the page might have : System.Environment.MachineName (might be useful in web farm scenarios) System.Environment.Version Environment.UserName database name current user's session ID Some of the info on this page might be sensitive from a security perspective. If you've done this sort of page before, what sort of security did you put on access to this page ? .

  • postgresql: Fast way to update the latest inserted row

    - by Anonymous
    What is the best way to modify the latest added row without using a temporary table. E.g. the table structure is id | text | date My current approach would be an insert with the postgresql specific command "returning id" so that I can update the table afterwards with update myTable set date='2013-11-11' where id = lastRow However I have the feeling that postgresql is not simply using the last row but is iterating through millions of entries until "id = lastRow" is found. How can i directly access the last added row?

  • chrome-like status bar in qt

    - by hasen j
    I'm not big on creating GUI's, and generally my philosophy is: I don't create them, or I make them as simple as possible (and convince myself that it's better for usability :) For my current project, I'm using Qt from Python (PyQt), and I want to start adding some GUI elements without cluttering the interface. My idea is to create these elements as sort of floating-shaped-widgets that only appear when necessary; pretty much like the status bar (and find bar) in chrome. Is there any standard api that enables creating this kind of interface?
