  • How do I show the print with AJAX/jQuery?

    - by Doug
    So I'm trying to understand this whole AJAX/jQuery thing. Right now, when I run this PHP script alone, I would have to wait and watch the wheel spin until it's done with the loop and then it will load. while ( $row = mysql_fetch_array($res) ) { postcode_to_storm( $row['Test'] ); $dom = new DOMDocument(); @$dom->loadHTML($result); $xPath = new DOMXPath($dom); $failInvite = 'Rejected'; $findFalse = strpos($result, $failInvite); if ( $findFalse == true ) { $array[$i] = $row['Test']; $i++; echo $array[$i]}; } } Now, how do I use AJAX/jQuery to show echo $array[$i]}; everytime it is invoked instead of waiting for the whole process to complete?

  • Getting object coordinates from camera

    - by user566757
    I've implemented a camera in Java using a position vector and three direction vectors so I can use gluLookAt(); moving around in `ghost mode' works fine enough, but I want to add collision detection. I can't seem to figure out how to transform my position vector to coordinates in which OpenGL draws my objects. A rough sketch of my drawing loop is this: glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); glLoadIdentity(); camera.setView(); drawer.drawTheScene(); I'm at a loss of how to proceed; looking at the ModelView matrix between calls and my position vector, I haven't found any kind of correlation.

  • How to retrieve large data from oracle database using vbscript

    - by allenzzzxd
    Hi guys, I'm now working on vbscript to do some test. Actuelly, I want to retrieve a large amount of data from an oracle database, so I write the code like this: sql = "Select * from CORE_DB where MC = '" & mstr & "' " Set myrs = db_execute_query(curConnection, sql) Then I count the rows in myrs,there are 248 rows. So then I do a For loop to retrieve some fields of each row. For k = 0 To db_get_rows_count(myrs) But then I found that the content of the row k when k 133 was always equal to k = 133. So this makes an error. As I think, there may be a limit size of mrys ? Could anyone light me about this? Thanks a lot in advance

  • Why is Postgres doing a Hash in this query?

    - by Claudiu
    I have two tables: A and P. I want to get information out of all rows in A whose id is in a temporary table I created, tmp_ids. However, there is additional information about A in the P table, foo, and I want to get this info as well. I have the following query: SELECT A.H_id AS hid, A.id AS aid, P.foo, A.pos, A.size FROM tmp_ids, P, A WHERE tmp_ids.id = A.H_id AND P.id = A.P_id I noticed it going slowly, and when I asked Postgres to explain, I noticed that it combines tmp_ids with an index on A I created for H_id with a nested loop. However, it hashes all of P before doing a Hash join with the result of the first merge. P is quite large and I think this is what's taking all the time. Why would it create a hash there? P.id is P's primary key, and A.P_id has an index of its own.

  • Does any language have a while-else flow structure?

    - by dotancohen
    Consider this flow structure which I happen to use often: if ( hasPosts() ) { while ( hasPosts() ) { displayNextPost(); } } else { displayNoPostsContent(); } Are there any programming languages which have an optional else clause for while, which is to be run if the while loop is never entered? Thus, the code above would become: while ( hasPosts() ) { displayNextPost(); } else { displayNoPostsContent(); } I find it interesting that many languages have the do-while construct (run the while code once before checking the condition) yet I have never seen while-else addressed. There is precedent for running an N block of code based on what was run in N-1 block, such as the try-catch construct. I wasn't sure whether to post here or on programmers.SE. If this question is more appropriate there, then please move it. Thanks.

  • C++: FFMPEG and SDL resources

    - by advs89
    I'm looking for resources (preferably books, but websites are fine too) for using FFMPEG and/or SDL with C++. Stuff I'd like to be able to do (eventually): Decode and play videos in realtime to a QT widget (the QT part isn't a problem) Overlay text and images on the video (in realtime) Loop video Cross-fade from one video to another (in realtime) Some kind of DVD functionality LIVE sources? (i.e. webcam, stream, etc.) So far I've looked at (and consider helpful) the following resources: FFMPEG and SDL Tutorial by Dranger (extremely helpful) StackOverflow: ffmpeg C API documentation/tutorial (not a duplicate, btw) Sample code bundled with FFMPEG libraries (I'll try and update this list with anything helpful below) Thanks for any help... Also: Operating System is Windows (but maybe one day cross-platform) Also 2: Resources using alternatives are welcome too... i.e. DirectShow, VFW, etc.

  • Faster way to compare two sets of points in N-dimensional space?

    - by Amit
    List1 contains a high number (~7^10) of N-dimensional points (N <=10), List2 contains the same or fewer number of N-dimensional points (N <=10). My task is this: I want to check which point in List2 is closest (euclidean distance) to a point in List1 for every point in List1 and subsequently perform some operation on it. I have been doing it the simple- the nested loop way when I didn't have more than 50 points in List1, but with 7^10 points, this obviously takes up a lot of time. What is the fastest way to do this? Any concepts from Computational Geometry might help?

  • First and last window don't show up.

    - by SirGregg
    Hi, I'm creating a WinApi application for my programming course. The program is supposed to show an LED clock using a separate window for each 'block'. I have figured most of it out, except for one thing: when creating the two-dimensional array of windows, the first and last window never show up. Here's the piece of code from the InitInstance function: for (int x=0;x<8;x++) for (int y=0;y<7;y++) { digitWnd[x][y] = CreateWindowEx((WS_EX_LAYERED | WS_EX_TRANSPARENT | WS_EX_NOACTIVATE | WS_EX_STATICEDGE), szWindowClass, szTitle, (WS_POPUP| WS_BORDER), NULL, NULL, NULL, NULL, dummyWnd, NULL, hInstance, NULL); ShowWindow(digitWnd[x][y], nCmdShow); UpdateWindow(digitWnd[x][y]); } The same loop bounds are used everytime I interact with the windows (set position and enable/disable). All the windows seem to be working fine, except for digitWnd[0][0] and digitWnd[7][6]... Any ideas as to what is happening?

  • Handling of data truncation (short reads/writes) in FUSE

    - by Vi
    I expect any good program should do all their reads and writes in a loop until all data written/read without relying that write will write everything (even with regular files). Am I right? Implemented simple FUSE filesystem which only allows reading and writing with small buffers, very often returning that it is written less bytes that in a buffer (using -o direct_io). Some programs work, some not (notably mountlo). Are them buggy or programs should not expect truncated writes and reads from the regular files? In general, are seekable file descriptors expected to truncate data like sockets and pipes?

  • getting the value of a filter at an arbitrary time

    - by Andiih
    Context: I'm trying to improve the values returned by the iPhone CLLocationManager, although this is a more generally applicable problem. The key is that CLLocationManger returns data on current velocity as and when it feels like it, rather than at a fixed sample rate. I'd like to use a feedback equation to improve accuracy v=(k*v)+(1-k)*currentVelocity where currentVelocity is the speed returned by didUpdateToLocation:fromLocation: and v is the output velocity (and also used for the feedback element). Because of the "as and when" nature of didUpdateToLocation:fromLocation: I could calculate the time interval since it was last called, and do something like for (i=0;i<timeintervalsincelastcalled;i++) v=(k*v)+(1-k)*currentVelocity which would work, but is wasteful of cycles. Especially as I probably want timeintervalsincelastcalled to be measured as 10ths of a second. Is there a way to solve this without the loop ? i.e. rework (integrate?) the formula so I put an interval into the equation and get the same answer as I would have by iteration ?

  • Dynamically adding Views in Silverlight & MVVM

    - by dvox
    Hi all, I am starting to re-write my whole silverlight business application in the MVVM pattern; My first stop-point is this: I have a page (View1) with corresponding ViewModel1 (with a property 'IEnumerable AllData'); Now, within this View, I want to have i.e. a tree-view control, in which one node will be populated with another View2; My question is: 1. How to do it? - I can't loop through the AllData property since it is asynchronously loaded... - thus I don't know the number of View2s' to insert - I don't know how to do it from ViewModel1 :( Will I need ViewModel2 with property 'MyDataEntity CurrentData'? or I can bind to AllData property from ViewModel1 Can you help me out? Thanks

  • Looping over some selected values in a stored procedure

    - by macca1
    I'm trying to modify a stored procedure hooked into an ORM tool. I want to add a few more rows based on a loop of some distinct values in a column. Here's the current SP: SELECT GRP = STAT_CD, CODE = REASN_CD FROM dbo.STATUS_TABLE WITH (NOLOCK) Order by STAT_CD, SRT_ORDR For each distinct STAT_CD, I'd also like to insert a REASN_CD of "--" here in the SP. However I'd like to do it before the order by so I can give them negative sort orders so they come in at the top of the list. I'm getting tripped up on how to implement this. Does anyone know how to do this for each unique STAT_CD?

  • Realtime processing and callbacks with Python and C++

    - by Doughy
    I need to write code to do some realtime processing that is fairly computationally complex. I would like to create some Python classes to manage all my scripting, and leave the intensive parts of the algorithm coded in C++ so that they can run as fast as possible. I would like to instantiate the objects in Python, and have the C++ algorithms chime back into the script with callbacks in python. Something like: myObject = MyObject() myObject.setCallback(myCallback) myObject.run() def myCallback(val): """Do something with the value passed back to the python script.""" pass Will this be possible? How can I run a callback in python from a loop that is running in a C++ module? Anyone have a link or a tutorial to help me do this correctly?

  • java Swing Listeners: components listening at each others.

    - by Pierre
    Hi all, I want to code two JList (categories and items). When I click one category it should select all the items for that category and when I click on one item it should select its categories. So both JList will have a ListSelectionListener listening at each other and changing the selection. Should I fear about some a of "loop" ? Is there a way to tell that an Event has been consumed ? how do people manage that kind of situation ? Thanks

  • Write a row to Google Spreadsheet programmically javascript

    - by Verber
    I'm trying to find a way to insert a row into a google spreadsheet dynamically. I have a list of objects that has all the data for every column in a row. I'm just trying to run a for loop and then send the data to the row in the spread sheet. But the spreadsheet is completely empty. So I don't know if that creates certain problems or not. for(var j=0; j < masterList.length; j++) { //tried this one but it didn't pan out sheet.appendRow([ masterList[j].Date, masterList[j].Name, masterList[j].Bugs, masterList[j].Enhancements, masterList[j].Epic, masterList[j].DevOps, masterList[j].High ]); }

  • Highest populated dimension of an array vba

    - by Ommit
    Say i have an single dimension array (to keep it simple). Is there a simple way to tell how many entries are populated, or the highest dimension of populated entries, other than to loop through and count them? I know Ubound finds the highest dimension of the array but that's not what I need. Is there something like Ubound but it only find populated entries, or the highest dimension populated? Also, what if the array is multidimensional. I'm working in excel vba.

  • convert std object class to comma seperated string

  • How to analyse Dalvik GC behaviour?

    - by HRJ
    I am developing an application on Android. It is a long running application that continuously processes sensor data. While running the application I see a lot of GC messages in the logcat; about one every second. This is most probably because of objects being created and immediately de-referenced in a loop. How do I find which objects are being created and released immediately? All the java heap analysis tools that I have tried(*) are bothered with the counts and sizes of objects on the heap. While they are useful, I am more interested in finding out the site where temporary short-lived objects get created the most. (*) I tried jcat and Eclipse MAT. I couldn't get hat to work on the Android heap-dumps; it complained of an unsupported dump file version.

  • Is there a better way to do SELECT queries in MySQL and sort them in PHP than this way?

    - by Kent
    I am just learning PHP/MySQL, one this I am having to do a lot is displaying data that was previously inserted into the database out to the user's browser. So I am doing this: $select = mysql_query('SELECT * FROM pages'); while ($return = mysql_fetch_assoc($select)) { $title = $return['title']; $author = $return['author']; $content = $return['content']; } then I can use these variables through out the page. Now, doing it the above way isn't an issue when I only have 3 columns in a database but what if I am dealing with a huge database with many more columns. I have a nagging feeling that the pros do it in some more efficient way where they maybe loop through the table they are selecting from to find all columns it has and associate them with variables automatically. Is that the case? or is the above how you guys do it too?

  • A $_GET input paramter that's an Array

    - by donpal
    I'm trying to pass 3 parameter to a script, where the 3rd parameter $_GET['value3'] is supposed to be an array $_GET['value1'] $_GET['value2'] $_GET['value3'] //an array of items I'm calling the script like this: (notice my syntax for value3, I'm not sure it's correct) http://localhost/test.php?value1=test1&value2=test2&value3=[the, array, values] I then use a foreach to hopefully loop through the third parameter value3 which is the array //process the first input $_GET['value1'] //process the second input $_GET['value2'] //process the third input $_GET['value3'] which is the array foreach($_GET['value3'] as $arrayitem){ echo $arrayitem; } but I get the error Invalid argument supplied for foreach() I'm not sure if my methodology is correct. Can some clarify how you'd go about doing the sort of thing

  • Dynamic Dropdown menu through php

    - by Code_Ed_Student
    I visited a website a few weeks ago and came across a dynamic drop down menu. I came across a functionality that I am now trying to replicate but do not know how. In the dropdown you picked the desired number of cars and then it reiterated input fields according to the number of cars chosen. I believe this was done through javascript and a loop was involved. Is there a term for this action or way to display things? Also an example of how to accomplish something similar would help?

  • How do you get the ID of a control in ASP.NET

    - by James
    I am attempting to loop through an array of numbers, match them to the checkbox they they are associated with, and checkmark that box. My checkbox is set up like: <input type="checkbox" runat="server" id="someID" name="somename" value="1234" /> My code when the page loads currently looks like: foreach (string interest in interests_Var){ foreach (var c in Page.Controls) { } } interests_Var is my array containing different numbers. We'll assume one of them is 1234. While looping through the page controls, I want to compare the value of the control to my number. If it equals my number, I want to then apply the attribute checked="checked". I'm assuming I have to find the ID of the control I am using, then use that ID to add a new attribute. Or is there a way I can add the attribute using the c variable? I'm not dead set on this setup, so if you know a better way, I'm all ears. Thanks for any help and suggestions.
