  • image hover animate

    - by Ryan Max
    Hello. I have the following jQuery script that makes an orange transparent hover effect cover the image when it's rolled over. How do I make it so this script will animate in and out (with a fade?) $(document).ready(function() { $('#gallery a').bind('mouseover', function(){ $(this).parent('li').css({position:'relative'}); var img = $(this).children('img'); $('<div />').text(' ').css({ 'height': img.height(), 'width': img.width(), 'background-color': 'orange', 'position': 'absolute', 'top': 0, 'left': 0, 'opacity': 0.5 }).bind('mouseout', function(){ $(this).remove(); }).insertAfter(this); }); });

Am I missing something? Thanks in advance

  • Looking for detailed explanation of Hibernate UserType methods for mutable objects

    - by Tom
    I am creating a custom UserType class in Hibernate. The specific case is for an HL7v3 clinical document (I work in health IT). It is a mutable object and most of the documentation around the Hibernate UserType interface seems to center around immutable types. I want a better understanding of how and when the interface methods are used, specifically: assemble - why two parameters (one Serializable, one Object)? What is the use case for this method? disassemble - should I just implement this method to return a serializable form (e.g. String representation)? When and how is this method invoked? equals - is this for update? read? contention? dirty reads? What are the consequences of simply returning false in most cases? replace - I really don't understand where the three Object parameters come from, when this method is invoked, and what Hibernate expects to return, or how that return value is used. Any pointers would be appreciated. I've searched and read all I can find on the subject, but have not found much documentation at all explaining how these methods are used for mutable objects.

  • Access to Perl's empty angle "<>" operator from an actual filehandle?

    - by Ryan Thompson
    I like to use the nifty perl feature where reading from the empty angle operator <> magically gives your program UNIX filter semantics, but I'd like to be able to access this feature through an actual filehandle (or IO::Handle object, or similar), so that I can do things like pass it into subroutines and such. Is there any way to do this? This question is particularly hard to google, because searching for "angle operator" and "filehandle" just tells me how to read from filehandles using the angle operator.

  • Why qry.post executed with asynchronous mode?

    - by Ryan
    Recently I met a strange problem, see code snips as below: var sqlCommand: string; connection: TADOConnection; qry: TADOQuery; begin connection := TADOConnection.Create(nil); try connection.ConnectionString := 'Provider=Microsoft.Jet.OLEDB.4.0;Data Source=Test.MDB;Persist Security Info=False'; connection.Open(); qry := TADOQuery.Create(nil); try qry.Connection := connection; qry.SQL.Text := 'Select * from aaa'; qry.Open; qry.Append; qry.FieldByName('TestField1').AsString := 'test'; qry.Post; beep; finally qry.Free; end; finally connection.Free; end; end; First, Create a new access database named test.mdb and put it under the directory of this test project, we can create a new table named aaa in it which has only one text type field named TestField1. We set a breakpoint at line of "beep", then lunch the test application under ide debug mode, when ide stops at the breakpoint line (qry.post has been executed), at this time we use microsoft access to open test.mdb and open table aaa you will find there are no any changes in table aaa, if you let the ide continue running after pressing f9 you can find a new record is inserted in to table aaa, but if you press ctrl+f2 to terminate the application at the breakpoint, you will find the table aaa has no record been inserted, but in normal circumstance, a new record should be inserted in to the table aaa after qry.post executed. who can explain this problem , it troubles me so long time. thanks !!! BTW, the ide is delphi 2010, and the access mdb file is created by microsoft access 2007 under windows 7

  • Can I reset a forgotten owner password with iText?

    - by Tom Hubbard
    With iText I can use Java to open a pdf and write it. If the pdf has an owner password I can still open it but it can not be written. Clearly the content is readable, it seems like at that point you could simply write the document to a new file. iText doesn't allow this, it throws a bad password exception. Is there a way around this?

  • DataView.RowFilter an ISO8601

    - by Ryan
    I have a DataTable (instance named: TimeTable) whose DefaultView (instance named: TimeTableView) I am trying to use to filter based on a date. Column clock_in contains an ISO8601 formatted string. I would like to select all the rows in this DataTable/DefaultView between 2009-10-08T08:22:02Z and 2009-10-08T20:22:02Z. What would I have to filter on this criteria? I tried: TimeTableView = TimeTable.DefaultView; TimeTableView.RowFilter = "clock_in >= #2009-10-08T08:22:02Z# and #2009-10-08T20:22:02Z#"; This is not working for me. Am I operating on the wrong object or is my filter syntax wrong?

  • Write directly to a remote Git repository, without adding objects to a local index/repo?

    - by Ryan B. Lynch
    Does Git support any commands that would allow me to commit directly from a local/working tree into a remote repository? The normal workflow requires a "git add", at least, to populate the object database with copies of the file contents, etc. I understand that this is NOT the normal, expected Git workflow. But I noticed that Git already supports downloading directly from the repository, with no local repo ("git archive"), so it seems reasonable that there might be a similar uploading operation. Alternatively, if there isn't such a command in the core Git itself, does any 3rd-party software support direct remote writes?

  • Extract XML name/value pairs from different nodes in Coldfusion

    - by Ryan French
    Hi All, I am working on some Plesk integration using the XML API and I am trying to figure out how to parse the XML response that I get back. Most of the data is fine, but the Limits and Permissions are setout differently. Essentially they are set out like so: <data> <limits> <limit> <name>foo</name> <value>bar</value> </limit> <limit> <name>foo2</name> <value>bar2</value> </limit> </limits> </data> How do I extract 'bar' from the xml given that I know I want the value of 'foo', but not the value of 'foo2'?

  • Finding the left-most and right-most points of a list. std::find_if the right way to go?

    - by Tom
    Hi, I have a list of Point objects, (each one with x,y properties) and would like to find the left-most and right-most points. I've been trying to do it with find_if, but i'm not sure its the way to go, because i can't seem to pass a comparator instance. Is find_if the way to go? Seems not. So, is there an algorithm in <algorithm> to achieve this? Thanks in advance. #include <iostream> #include <list> #include <algorithm> using namespace std; typedef struct Point{ float x; float y; } Point; bool left(Point& p1,Point& p2) { return p1.x < p2.x; } int main(){ Point p1 ={-1,0}; Point p2 ={1,0}; Point p3 ={5,0}; Point p4 ={7,0}; list <Point> points; points.push_back(p1); points.push_back(p2); points.push_back(p3); points.push_back(p4); //Should return an interator to p1. find_if(points.begin(),points.end(),left); return 0; }

  • Installed Programs/Computer Info for Web Application

    - by Ryan Gyure
    I'm currently developing a support system for a university. The system is written in PHP and I would like to be able to get a current list of software and basic computer information on a computer. Basically when one of the faculty or staff creates a ticket from our web interface, I would like to have a Java Applet or similar that could be run and would return the information to the help desk PHP script. Does something like this exist?

  • Importing a large delimited file to a MySQL table

    - by Tom
    I have this large (and oddly formatted txt file) from the USDA's website. It is the NUT_DATA.txt file. But the problem is that it is almost 27mb! I was successful in importing the a few other smaller files, but my method was using file_get_contents which it makes sense why an error would be thrown if I try to snag 27+ mb of RAM. So how can I import this massive file to my MySQL DB without running into a timeout and RAM issue? I've tried just getting one line at a time from the file, but this ran into timeout issue. Using PHP 5.2.0. Here is the old script (the fields in the DB are just numbers because I could not figure out what number represented what nutrient, I found this data very poorly document. Sorry about the ugliness of the code): <? $file = "NUT_DATA.txt"; $data = split("\n", file_get_contents($file)); // split each line $link = mysql_connect("localhost", "username", "password"); mysql_select_db("database", $link); for($i = 0, $e = sizeof($data); $i < $e; $i++) { $sql = "INSERT INTO `USDA` (1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17) VALUES("; $row = split("\^", trim($data[$i])); // split each line by carrot for ($j = 0, $k = sizeof($row); $j < $k; $j++) { $val = trim($row[$j], '~'); $val = (empty($val)) ? 0 : $val; $sql .= ((empty($val)) ? 0 : $val) . ','; // this gets rid of those tildas and replaces empty strings with 0s } $sql = rtrim($sql, ',') . ");"; mysql_query($sql) or die(mysql_error()); // query the db } echo "Finished inserting data into database.\n"; mysql_close($link); ?>

  • Dual slider control with custom skin

    - by Ryan French
    Hi All, I'm currently trying to create a page for users to select two points from a range, using a slide control. The first point in the range is when an alert will be sent to the user, the second point is a max limit. What I would like to do is have the bar colored green from the 0 point to the first slider point, then orange between the two sliders, and lastly red from the second slider up to the other end of the bar. Does anyone know of an easy was I can do this or of a slider control that can be skinned to do this?

  • Creating a Large Matrix in ff

    - by Ryan Rosario
    I am trying to create a huge matrix in ff, and I know that ff is good for this sort of thing. But, there is a major problem. The dimensions of the matrix exceed .Machine$max_integer! I am running on a 64 bit machine, using 64bit R and 64bit ff. Is there any way to get around this problem? It's been suggested that R is using the MAXINT value from stdint.h. Is there any way to fix this without changing that file and possibly breaking build? > ffMatrix <- ff(vmode="boolean", dim=c(1e10,1e10)) Error in if (length < 0 || length > .Machine$integer.max) stop("length must be between 1 and .Machine$integer.max") : missing value where TRUE/FALSE needed In addition: Warning message: In ff(vmode = "boolean", dim = c(1e+10, 1e+10)) : NAs introduced by coercion > 1e+10 > .Machine$integer.max [1] TRUE

  • Exactly clone an object in javascript

    - by Tom
    Hi, I tried to exactly clone an object in javascript. I know the following solution using jquery: var newObject = jQuery.extend({}, oldObject); // Or var newObject = jQuery.extend(true, {}, oldObject); but the problem with that is, that the objects type gets lost: var MyClass = function(param1, param2) { alert(param1.a + param2.a); }; var myObj = new MyClass({a: 1},{a: 2}); var myObjClone = jQuery.extend(true, {}, myObj); alert(myObj instanceof MyClass); // => true alert(myObjClone instanceof MyClass); // => false Is there any solution to get true on the second alert?

  • Problem with WHERE columnName = Data in MySQL query in C#

    - by Ryan Sullivan
    I have a C# webservice on a Windows Server that I am interfacing with on a linux server with PHP. The PHP grabs information from the database and then the page offers a "more information" button which then calls the webservice and passes in the name field of the record as a parameter. So i am using a WHERE statement in my query so I only pull the extra fields for that record. I am getting the error: System.Data.SqlClient.SqlException:Invalid column name '42' Where 42 is the value from the name field from the database. my query is string selectStr = "SELECT name, castNotes, triviaNotes FROM tableName WHERE name =\"" + show + "\""; I do not know if it is a problem with my query or something is wrong with the database, but here is the rest of my code for reference. NOTE: this all works perfectly when I grab all of the records, but I only want to grab the record that I ask my webservice for. public class ktvService : System.Web.Services.WebService { [WebMethod] public string moreInfo(string show) { string connectionStr = "MyConnectionString"; string selectStr = "SELECT name, castNotes, triviaNotes FROM tableName WHERE name =\"" + show + "\""; SqlConnection conn = new SqlConnection(connectionStr); SqlDataAdapter da = new SqlDataAdapter(selectStr, conn); DataSet ds = new DataSet(); da.Fill(ds, "tableName"); DataTable dt = ds.Tables["tableName"]; DataRow theShow = dt.Rows[0]; string response = "Name: " + theShow["name"].ToString() + "Cast: " + theShow["castNotes"].ToString() + " Trivia: " + theShow["triviaNotes"].ToString(); return response; } }

  • Showing renames in hg status?

    - by Ryan Thompson
    I know that Mercurial can track renames of files, but how do I get it to show me renames instead of adds/removes when I do hg status? For instance, instead of: A bin/extract-csv-column.pl A bin/find-mirna-binding.pl A bin/xls2csv-separate-sheets.pl A lib/Text/CSV/Euclid.pm R src/extract-csv-column.pl R src/find-mirna-binding.pl R src/modules/Text/CSV/Euclid.pm R src/xls2csv-separate-sheets.pl I want some indication that four files have been moved. I think I read somewhere that the output is like this to preserve backward-compatibility with something-or-other, but I'm not worried about that.

  • getting around circular references in Delphi

    - by Tom
    Is there a way of getting around circular unit references in Delphi? Maybe a newer version of delphi or some magic hack or something? My delphi project has 100 000+ lines of code mostly based on singleton classes. I need to refactor this, but that would mean several months of "circular reference" hell :)

  • Is there a version of the .Net Redistributable bundled with all supported versions of Windows?

    - by Tom the Junglist
    Hi there, Is there a specific version of .Net that I can target that is bundled with all versions of Windows of XP SP2 and higher? We are trying to create a simple setup stub without having to resort to a low-level C/C++ app... currently something is cooked up in VB6, but there's a fair amount of low-level network code that I would much rather rewrite in .Net -- which would be trivial if only we could rely on the presence of a given version.
