  • How to load an image in matlab from java

    - by Ian
    Basically I am trying to create a little program that will allow me to make calls in matlab from a jave GUI It's mainly going to be used for image manipulation and deblurring but I am struggling to find a way that will effectively give me full matlab control from the java end I am hoping to have it work like so: { //create matlab execution call String loadImage = " image1 = imread ('imageOnComputer.jpg'); "; //send instruction to matlab and save the path to it so java can //use the newly created variable resultingVariablePath = java.sendInstructionToMatlab(loadImage); //display on the screen java.displayImage(resultingVariablePath); } Basically I am just trying to find out if there is a plugin for matlab (or some java package) that will grant you (pretty much) full control over matlab.

  • SQL Native Client 10 Performance miserable (due to server-side cursors)

    - by namezero
    we have an application that uses ODBC via CDatabase/CRecordset in MFC (VS2010). We have two backends implemented. MSSQL and MySQL. Now, when we use MSSQL (with the Native Client 10.0), retrieving records with SELECT is dramatically slow via slow links (VPN, for example). The MySQL ODBC driver does not exhibit this nasty behavior. For example: CRecordset r(&m_db); r.Open(CRecordset::snapshot, L"SELECT a.something, b.sthelse FROM TableA AS a LEFT JOIN TableB AS b ON a.ID=b.Ref"); r.MoveFirst(); while(!r.IsEOF()) { // Retrieve CString strData; crs.GetFieldValue(L"a.something", strData); crs.MoveNext(); } Now, with the MySQL driver, everything runs as it should. The query is returned, and everything is lightning fast. However, with the MSSQL Native Client, things slow down, because on every MoveNext(), the driver communicates with the server. I think it is due to server-side cursors, but I didn't find a way to disable them. I have tried using: ::SQLSetConnectAttr(m_db.m_hdbc, SQL_ATTR_ODBC_CURSORS, SQL_CUR_USE_ODBC, SQL_IS_INTEGER); But this didn't help either. There are still long-running exec's to sp_cursorfetch() et al in SQL Profiler. I have also tried a small reference project with SQLAPI and bulk fetch, but that hangs in FetchNext() for a long time, too (even if there is only one record in the resultset). This however only happens on queries with LEFT JOINS, table-valued functions, etc. Note that the query doesn't take that long - executing the same SQL via SQL Studio over the same connection returns in a reasonable time. Question1: Is is possible to somehow get the native client to "cache" all results locally use local cursors in a similar fashion as the MySQL driver seems to do it? Maybe this is the wrong approach altogether, but I'm not sure how else to do this. All we want is to retrieve all data at once from a SELECT, then never talk the server again until the next query. We don't care about recordset updates, deletes, etc or any of that nonsense. We only want to retrieve data. We take that recordset, get all the data, and delete it. Question2: Is there a more efficient way to just retrieve data in MFC with ODBC?

  • Hbase schema design -- to make sorting easy?

    - by chen
    I have 1M words in my dictionary. Whenever a user issue a query on my website, I will see if the query contains the words in my dictionary and increment the counter corresponding to them individually. Here is the example, say if a user type in "Obama is a president" and "Obama" and "president" are in my dictionary, then I should increment the counter by 1 for "Obama" and "president". And from time to time, I want to see the top 100 words (most queried words). If I use Hbase to store the counter, what schema should I use? -- I have not come up an efficient one yet. If I use word in my dictionary as row key, and "counter" as column key, then updating counter(increment) is very efficient. But it's very hard to sort and return the top 100. Anyone can give a good advice? Thanks.

  • Is there a better way to serially submit multiple AJAX requests?

    - by friedo
    I have a page with multiple forms that I submit via Ajax POSTs serially. At first, I tried using synchronous XHR requests, but this causes the browser to lock up for the duration of the request, and breaks my DOM-manipulation effects, which is unacceptable. So the pattern I ended up using is basically this: var fcount = 0; // incremented for each form to be submitted function submit_form( num ) { var fdata = { ... }; // data from form # num $.ajax( { async: true, url: '/index.cgi', data: fdata, type: 'POST', success: function() { if ( num < fcount ) { submit_form( ++num ); } } } ); } $( '#submit_form_btn' ).click( function() { submit_form( 1 ) } ); The recursion strikes me as a bit of an ugly solution to what is essentially an iterative problem. Is there a cleaner or more elegant way that this could be handled?

  • Creating a Variable of Present Date Minus a Past Timestamp

    - by John
    Hello, In the code below, "created" is a field in a MySQL table. This field is of the type "timestamp" and the default is set to "CURRENT_TIMESTAMP" of whenever a given row is created. In the query below, I would like to create a new variable that equals the present date minus the timestamp of "created", rounded off to units of days. I would like the present date to be whenever the query is run. How could I do this? Thanks in advance, John $sqlStr = "SELECT l.loginid, l.username, l.created, ...

  • @media queries - one rule overrides another?

    - by John
    I have multiple @media queries all working fine but as soon as i put in a higher max screen-width than 1024px the rules for the higher width gets applied to everything. @media screen and (max-width: 1400px) { #wrap { width: 72%; } } @media screen and (max-width: 1024px) { #slider h2 { width: 100%; } #slider img { margin: 60px 0.83333333333333% 0 2.08333333333333%; } .recent { width: 45.82%; margin: 10px 2.08333333333334% 0 1.875%; } } as you can see 1024px (and also the 800px max-width query) do not change the #wrap width and work fine. As soon as i add the 1400px max-width query it changes them to 72% for ALL sizes and does the same for any element - for instance if i set #slider img to have a margin of 40px it will show at ALL sizes even though it is only in the max-width of 1400px. Am i missing something really obvious? Been trying to work this out for the past 2 days! Thanks, John

  • sqlplus remove \r \n \t from spool

    - by Tom
    Hi all, Is there any sql*plus command to remove \r \n and\t from the result set that's going out to the spool file? That is, "trim" every record? We've used set trim on in the past, but it doesn't seem to bue what we need right now. I'm trying to avoid calling oracle's translate, chr functions in the sql query. For example, If my query returns this |DATA| |\n \t\t\t\t\t thisistheactualdata \t\t\t\t\t\t\n| I'd like to keep this |DATA| |thisistheactualdata| Thanks in advance.

  • How to dynamically order many-to-many relationship in JPA or HQl?

    - by Indrek
    I have a mapping like this: @ManyToMany(cascade = CascadeType.PERSIST) @JoinTable( name="product_product_catalog", joinColumns={@JoinColumn(name="product_catalog", referencedColumnName="product_catalog")}, inverseJoinColumns={@JoinColumn(name="product", referencedColumnName="product")}) public List<Product> products = new ArrayList<Product>(); I can fetch the products for the catalog nicely, but I can't (dynamically) order the products. How could I order them? I probably have to write a many-to-many HQL query with the order-by clause? I though of passing the orderBy field name string to the query, or is there a better solution? Tables are: products, product_catalog, product_product_catalog (associative table) P.S. Using Play! Framework JPASupport for my entities.

  • SQL Querying for Threaded Messages

    - by Harper
    My site has a messaging feature where one user may message another. The messages support threading - a parent message may have any number of children but only one level deep. The messages table looks like this: Messages - Id (PK, Auto-increment int) - UserId (FK, Users.Id) - FromUserId (FK, Users.Id) - ParentMessageId (FK to Messages.Id) - MessageText (varchar 200) I'd like to show messages on a page with each 'parent' message followed by a collapsed view of the children messages. Can I use the GROUP BY clause or similar construct to retrieve parent messages and children messages all in one query? Right now I am retrieving parent messages only, then looping through them and performing another query for each to get all related children messages. I'd like to get messages like this: Parent1 Child1 Child2 Child3 Parent2 Child1 Parent3 Child1 Child2

  • Basic class returns onject reference instead of Array

But what I want is the MySQL row array from the mysql_fetch_row() call... What am I missing?

  • Echoing a pseudo column value after a COUNT

    - by rob - not a robber
    Hi Gang... Please don't beat me if this is elementary. I searched and found disjointed stuff relating to pseudo columns. Nothing spot on about what I need. Anyway... I have a table with some rows. Each record has a unique ID, an ID that relates to another entity and finally a comment that relates to that last entity. So, I want to COUNT these rows to basically find what entity has the most comments. Instead of me explaining the query, I'll print it SELECT entity_id, COUNT(*) AS amount FROM comments GROUP BY entity_id ORDER BY amount DESC The query does just what I want, but I want to echo the values from that pseudo column, 'amount' Can it be done, or should I use another method like mysql_num_rows? Thank you!!!

  • using jquery to load data from mysql database

    - by Ieyasu Sawada
    I'm currently using jquery's ajax feature or whatever they call it. To load data from mysql database. Its working fine, but one of the built in features of this one is to load all the data which is on the database when you press on backspace and there's no character left on the text box. Here's my query: SELECT * FROM prod_table WHERE QTYHAND>0 AND PRODUCT LIKE '$prod%' OR P_DESC LIKE '$desc%' OR CATEGORY LIKE '$cat%' As you can see I only want to load the products which has greater than 0 quantity on hand. I'm using this code to communicate to the php file which has the query on it: $('#inp').keyup(function(){ var inpval=$('#inp').val(); $.ajax({ type: 'POST', data: ({p : inpval}), url: 'querys.php', success: function(data) { $('.result').html(data); } }); }); Is it possible to also filter the data that it outputs so that when I press on backspace and there's no character left. The only products that's going to display are those with greater than 0 quantity?

I can't figure out why. Any ideas?

  • Java Session Like Object

    - by scriptmonster
    I have been developing a project and in this project i have designed my code to do the same job after a specified time interval continuously. The job that wanted to be done has a lot of distinct cycles. The interval is small to execute them normally thus i used threads. Until that point everything is clear for me. To decrease the process and information transaction i wanted to put an session like object that holds the given data and provide it to any thread at anytime. With this object i plan to not query the same configuration information from database at everytime but if it exists on the session take it else query and store on session. I'm not sure how to implement this structure. Regards,

  • What's the best way to apply a drop shadow?

    - by jckeyes
    What is the best method for applying drop shadows? I'm working on a site right now where we have a good deal of them, however, I've been fighting to find the best method to do it. The site is pretty animation heavy so shadows need to work well with this. I tried a jQuery shadow pulgin. The shadows looked good and were easy to use but were slow and didn't work well with any animations (required lots of redrawing, very joggy). I also tried creating my own jQuery extension that wraps my element in a couple gray divs and then offsets them a little bit to give a shadow effect. This worked well. It's quick and responsive to the animation. However, it makes DOM manipulation/traversal cumbersome since everything is wrapped in these shadow divs. I know there has to be a better way but this isn't exactly my forte. Thoughts?

  • How do I alternate table row colors in asp.net mvc using jquery?

    Probably a dumb question but I'm new to MVC and jQuery. I want to alternate the row colors of my tables and I've decided that I'm going to use jQuery to do it. I know that I could write an extension method (http://haacked.com/archive/2008/08/07/aspnetmvc_cycle.aspx), etc but after reading SH's comment on the article at http://haacked.com/archive/2008/05/03/code-based-repeater-for-asp.net-mvc.aspx I've picked jQuery as the solution I want to implement. I want to implement the method described at http://www.packtpub.com/article/jquery-table-manipulation-part2 but I haven't figured out where to put the initial jQuery call (eg: $(document).ready(function() {...}); Like I said, I'm new to jQuery...

  • Fetch pages translated by Google? (PHP)

    - by mathon12
    Hi, I have a bunch of big txt files (game walkthroughs) that I need translating from English to French. My first instinct was to host them on a server and use a PHP script to automate the translation process by doing a file_get_contents() and some URL manipulation to get the translated text. Something like: http://translate.google.com/translate?hl=fr&sl=en&u=http://mysite.com/faq.txt I found it poses two problems: 1) there are frames 2) the frame src values are relative (ie src="/translate_c?....") so nothing loads. Is there any way to fetch pages translated via Google in PHP (without using their AJAX API as it's really not suitable here)?
