  • Pull datasets from DB and manipulate into separate arrays

    - by dresdin
    My DB has four fields, date:date, morning:integer, afternoon:integer, evening:integer. Google charts needs the data split into one array per dataset (example below). What's the best way to do this? ['Day', 'Morning', 'Afternoon', 'Evening'], ['06/27/13', 1000, 400 234], ['06/28/13', 1170, 460 275], ['06/29/13', 660, 1120 377], ['06/30/13', 1030, 540 934] I've tried this without much luck: var data = google.visualization.arrayToDataTable([ <% @todo.each do |t| %> ['Day', 'Morning', 'Afternoon', 'Evening'], [<%= t.date.strftime("%m/%d/%y") %>, <%= t.morning %>, <%= t.afternoon %>, <%= t.evening %>] <% end %> ]);

  • Qt - arguments in signal-slots

    - by bullettime
    I have a QPushButton, QDateEdit and another custom object. I want to connect the button to the date edit object in a way that when I click the button, the date edit object will change its set date to a date defined on the custom object. Kinda like this: connect(pushbutton,SIGNAL(clicked()),dateedit,SLOT(setDate(custom_object.getDate()))); but I can't do that. Apparently, the connect statement doesn't specify what's the information being passed from the signal to the slot, only the type of the information being passed. Is there a way to do this without having to create a new class?

  • Question about "Link Map" output and "Assume" directive of MASM assembler.

    - by smwikipedia
    I am new to MASM. So the questions may be quite basic. When I am using the MASM assembler, there's an output file called "Link Map". Its content is composed of the starting offset and length of various segments, such as Data segment, Code segment and Stack segment. I am wondering that, where are these information describing? Are they talking about how various segments are located within an EXE file or, how segments are located within memory after the EXE file being loaded into memory by a program loader? BTW: What does the "Assume" directive do? My understanding is that it tell the assembler to emit some information into the exe file header so the program loader could use it to set DS, CS, SS, ES register accordingly. Am I right on this? Thanks in advance.

  • ColdFusion's cfquery failing silently

    - by johnthexiii
    I have a query that retrieves a large amount of data. <cfsetting requesttimeout="9999999" > <cfquery name="randomething" datasource="ds" timeout="9999999" > SELECT col1, col2 FROM table </cfquery> <cfdump var="#randomething.recordCount#" /> <!---should be about 5 million rows ---> I can successfully retrieve the data with python's cx_Oracle and using sys.getsizeof on the python list returns 22621060, so about 21 megabytes. ColdFusion does not return an error on the page, and I can't find anything in any of the logs. Why is cfdump not showing the number of rows? Additional Information The reason for doing it this way is because I have about 8000 smaller queries to run against the randomthing query. In other words when I run those 8000 queries against the database it takes hours for that process to complete. I suspect this is because I am competing with several other database users, and the database is getting bogged down. The 8000 smaller queries are getting counts of col1 over a period of col2. SELECT count(col1) as count WHERE col2 < 20121109 AND col2 > 20121108 According to Adam Cameron's suggestions. cflog is suggesting that the query isn't finishing. I tried changing the queries timeout both in the code and in the CFIDE/administrator, apparently CF9 no long respects the timeout attribute, regardless of what I tried I couldn't get the query to timeout. I also started playing around with the maxrows attribute to see if I could discern any information that way. when maxrows is set to 1300000 everything works fine when maxrows is 1400000 or greater I get this error when maxrows is 2000000 I observe my original problem Update So this isn't a limit of cfquery. By using QueryNew then looping over it to add data and I can get well past the 2 million mark without any problems. I also created a ThinClient datasource using the information in this question, I didn't observe any change in behavior. The messages on the database end are SQL*Net message from client and SQL*Net more data to client I just discovered that by using the thin client along with blockfactor1="100" I can retrieve more rows (appx. 3000000).

  • Code for adding Content Controls Word 2007 C#

    - by AProgrammer
    Hey all, I was wondering if anyone has any idea how I can add Content Controls to a Word Document (Office 2007) from the Document Task/Action Pane via C#. The goal is the following: I want to have categorized information in the Task/Action Pane and have the user fill out the info there. Once they have filled out that information they'll click on a button and it will insert content Controls into the Word Document that has that Data. The reason I want to use Content Controls is because the data will be bound to a database. Is this possible? I would like links that do this without WordProcessingML or OpenXML. There has to be a way to do this via server side code and such that doesn't require long blocks of ,, etc. Thanks!

  • How to read pixel values of a video?

    - by vikramtheone
    Hi Guys, I recently wrote C programs for image processing of BMP images, I had to read the pixel values and process them, it was very simple I followed the BMP header contents and I could get most of the information of the BMP image. Now the challenge is to process videos (Frame by Frame), how can I do it? How will I be able to read the headers of continuous streams of image frames in a video clip? Or else, is it like, for example, the mpeg format will also have universal header, upon reading which I can get the information about the entire video and after the header, all the data are only pixels. I hope I could convey. Has anyone got experience with processing videos? Any books or links to tutorials will be very helpful. Vikram

  • Getting RGB values for each pixel from a 24bpp Bitmap in C

    - by seven
    Hello, i want to read the RGB values for each pixel from a .bmp file , so i can convert the bmp into a format suitable for gba . so i need to get just the RGB for each pixel and then write this information to a file. i am trying to use the windows.h structures : typedef struct { char signature[2]; unsigned int fileSize; unsigned int reserved; unsigned int offset; }BmpHeader; typedef struct { unsigned int headerSize; unsigned int width; unsigned int height; unsigned short planeCount; unsigned short bitDepth; unsigned int compression; unsigned int compressedImageSize; unsigned int horizontalResolution; unsigned int verticalResolution; unsigned int numColors; unsigned int importantColors; }BmpImageInfo; typedef struct { unsigned char blue; unsigned char green; unsigned char red; unsigned char reserved; }Rgb; typedef struct { BmpHeader header; BmpImageInfo info; Rgb colors[256]; unsigned short image[1]; }BmpFile; but i only need RGB struct. So lets say i read "in.bmp": FILE *inFile, *outFile; inFile = fopen("C://in.bmp", "rb"); Rgb Palette[256]; for(i=0;i<256;i++) { fread(&Palette[i],sizeof(Rgb),1,inFile); } fclose(inFile); is this correct ? how do i write only the RGB information to a file ? can anyone please give me some information please . Thank you.

  • Core dump utility for .NET

    - by Dave
    In my past life as a COBOL mainframe developer I made extensive use of a tool called Abendaid which, in the event of an exception, would give me a complete memory dump including a formatted list of every variable in memory as well as a complete stack trace of the program with the offending statement highlighted. This made pinpointing the cause of an error much simpler and saved a lot of step-through debugging and/or trace statements. Now I've made the transition to C# and .NET web development I find that the information provided by ASP.NET only tells half the story, giving me a stack trace, but not any of the variable or class information. This makes debugging more difficult as you then have to run the process again with the debugger to try and reproduce the error, not easy with intermittent errors or with assemblies that run under the likes of SQL Server or CRM. I've looked around quite a lot for something that does this but I can't find anything obvious. Does anyone have any idea if there is one, or if not, what I'd need to start with in order to write one?

  • Need Help on OAuthException Code 2500

    - by Deepak
    I am trying to develop an Facebook application (apps.facebook.com/some_app) using PHP where I need to present some information based on user's music interests. I found that its under "user_likes games". My problems are as follows: To gain access, I have implemented the oauth dialog method as suggested in API in my index page. $auth_url = "http://www.facebook.com/dialog/oauth?client_id=" . $app_id . "&redirect_uri=" . urlencode($canvas_page) ."&scope=user_likes"; After successful authorization I come back to index page with "code" as parameters. http://MY_CANVAS_PAGE/?code=some base64 encoded letters Firstly I don't know if I need access_token just to read user's music interests but I have tried all the methods suggested. I couldn't move forward from this point I have a code like this (in my index page), which redirects for authorization if code parameters is not set. if(empty($code) && !isset($_REQUEST['error'])) { $_SESSION['state'] = md5(uniqid(rand(), TRUE)); //CSRF protection echo("<script> top.location.href='" . $auth_url . "'</script>"); } Currently I am just trying to get user's public information here but with no success. I have tried the signed_request method as suggested but no success $signed_request = $_REQUEST["signed_request"]; list($encoded_sig, $payload) = explode('.', $signed_request, 2); $data = json_decode(base64_decode(strtr($payload, '-_', '+/')), true); echo ("Welcome User: " . $data["user_id"]); Also tried the code found in http://developers.facebook.com/blog/post/500/ but I am getting error when trying to get the debug info using print_r($decoded_response); stdClass Object ( [error] => stdClass Object ( [message] => An active access token must be used to query information about the current user. [type] => OAuthException [code] => 2500 ) ) To get user's public info, I have tried also the suggested example in PHP SDK $facebook = new Facebook(array( 'appId' => MY_APP_ID, //registered facebook APP ID 'secret' => MY_SECRET, //secret key for APP )); $fb_user = $facebook->getUser(); if($fb_user){ try { $user_profile = $facebook->api('/me'); echo $user_profile['email']; } catch(FacebookApiException $e) { $fb_user = null; } } But no success. Can somebody explain me why I am getting this error and how to access the user's music interest properly. Probably I misunderstood the API. Thanks Deepak

  • Graphical database monitoring tool for debugging

    - by salle55
    I would love a tool that in real-time showed changes in a set of predefined tables in a graphical way, for example different colors on fields that has changed value, added records, deleted records etc. I don't want a list of all transactions (like SQL Server Profiler), instead a clever visualized more graphical approach where you can get a great overview if you are just monitoring a few tables. I realize the visualization would be hard if there is a lot of transactions against the database, but with monitoring on a few tables and a single session during debugging it would be possible. Does something like this exist? I think it would be great for debugging! Preferably for SQL Server and/or MySQL.

  • Object reference error even when object is not null

    - by Shrewd Demon
    hi, i have an application wherein i have incorporate a "Remember Me" feature for the login screen. I do this by creating a cookie when the user logs in for the first time, so next time when the user visits the site i get the cookie and load the user information. i have written the code for loading user information in a common class in the App_Code folder...and all my pages inherit from this class. code for loading the user info is as follows: public static void LoadUserDetails(string emailId) { UsersEnt currentUser = UsersBL.LoadUserInfo(emailId); if (currentUser != null) HttpContext.Current.Session["CurrentUser"] = currentUser; } Now the problem is i get an "Object reference" error when i try to store the currentUser object in the session variable (even though the currentUser object is not null). However the password property in the currentUser object is null. Am i getting the error because of this...or is there some other reason?? thank you

  • Basic Login Script using php and mysql inquiry

    - by Matt
    Attempting to write a check for a login script to see if the username is available. Would the best way to write this query be to check if isset(!_POST[]) for both values (nick and pass) then connect to database WHERE the mysql database for the usernick requested return the user id if the usernick exists evaluate if isset($id) to see if the user name is taken and use that to continue to creating an entry Does this logically sound like a method to check for login without using excessive code sorry for not posting the code, it is on another computer and this computer is locked down by my administrator at work... Also, is there another way to evaluate if a value exists in the database? For instance, instead of setting $id to the return value of the mysql database can i just ping the mysql database for the information and have it return a Boolean result so I am not putting out any user information. Thanks, Matt

    Say i make a get request like this: GET http://cotnet.diggstatic.com:6000/js/loader/443/JS_Libraries,jquery|Class|analytics|lightbox|label|jquery-dom|jquery-cookie?q=hello#frag HTTP/1.0 Host: cotnet.diggstatic.com:6000 My servlet takes request like this: HttpServletRequest req; When i debug my server and execute, i get the following: req.getRequestURL().toString() = "http://cotnet.diggstatic.com:6000/js/loader/443/JS_Libraries,jquery%7cClass%7canalytics%7clightbox%7clabel%7cjquery-dom%7cjquery-cookie" req.getRequestURI() = "/js/loader/443/JS_Libraries,jquery%7cClass%7canalytics%7clightbox%7clabel%7cjquery-dom%7cjquery-cookie" req.getQueryString() = "q=hello" How does one get the fragment information ? Also, when i debug the request, i see a uri_ field of type java.net.URI which has the fragment information. This is exactly what i want. How can i get that ?

  • SharePoint - DIP problem on local copies downloaded from the portal

    - by user255234
    Our users have issues where the Document Information Panel(DIP) appears on Word, Excel, PPT documents. Here is the scenario: User downloads a copy of a template from the portal to his/her local hard drive. User edits that template and renames the file, again saving it to his/her local drive. User continues to edit and update that new document, and it continues to prompt him/her for document information as if the user was saving it on the portal. User clicks the “X” to remove this DIP bar, the next time he/she opens the local file it comes back. Is there anything I can do to make the DIP NOT SHOW on the local copies? Thanks!

  • Playing audio from a wav file in iPhone SpeakHere example

    - by Mo
    I'm working with the iPhone SpeakHere example, and I would like to be able to play audio from either the mic (as in the example) or from a wav file. I have working code to play from a particular wav file, which looks like this: NSString *path = [[NSBundle mainBundle] pathForResource:@"basketBall" ofType:@"wav"]; AVAudioPlayer* theAudio=[[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:NULL]; theAudio.delegate = self; [theAudio play]; So I'm fine with actually getting the wav to play in the application (I can hook it up to a button, etc.) but I would like it to also behave the same way pushing the "Play" button does after recorded speech, in that it should be connected to the same visualization (which I have modified quite a bit, but essentially shows the current volume, among other things). Thanks for your help!

  • Range partition skip check

    - by user289429
    We have large amount of data partitioned on year value using range partition in oracle. We have used range partition but each partition contains data only for one year. When we write a query targeting a specific year, oracle fetches the information from that partition but still checks if the year is what we have specified. Since this year column is not part of the index it fetches the year from table and compares it. We have seen that any time the query goes to fetch table data it is getting too slow. Can we somehow avoid oracle comparing the year values since we for sure know that the partition contains information for only one year.

  • Using java.util.logging, is it possible to restart logs after a certain period of time?

    - by Fry
    I have some java code that will be running as an importer for data for a much larger project. The initial logging code was done with the java.util.logging classes, so I'd like to keep it if possible, but it seems to be a little inadequate now given he amount of data passing through the importer. Often times in the system, the importer will get data that the main system doesn't have information for or doesn't match the system's data so it is ignored but a message is written to the log about what information was dropped and why it wasn't imported. The problem is that this tends to grow in size very quickly, so we'd like to be able to start a fresh log daily or weekly. Does anybody have an idea if this can be done in the logging classes or would I have to switch to log4j or custom? Thanks for any help!

  • Is there any graphics library in a higher level than OpenGL

    - by Turtle
    Hello, I am looking for a graphics library for 3D reconstruction research to develop my specific viewer based on some library. OpenGL seems in a low level and I have to remake the wheel everywhere. And I also tried VTK(visualization toolkit). However, it seems too abstract that I need to master many conceptions before I start. Is there any other graphics library? I prefer to program in python. So I would like the library has a python wrapper. I think something like O3D would be better. But O3D is for javascript and it seems that Google already stops the development.

  • What should I really release as open source when I use Berkeley DB (JE)?

    - by Ersin Er
    The Berkeley DB (JE) license information says: "...Redistributions in any form must be accompanied by information on how to obtain complete source code for the DB software and any accompanying software that uses the DB software.... For an executable file, complete source code means the source code for all modules it contains. It does not include source code for modules or files that typically accompany the major components of the operating system on which the executable file runs." If I build an abstraction level on top of BDB JE, should I open source only that library or any software that uses BDB JE indirectly?

  • Is there a good reflection library available for Scala?

    - by Erik Engbrecht
    I'm working on a library that needs reflection, and needs Scala-specific information as opposed to what is available via the standard Java reflection API. Right now I'm using the undocumented code in scalap (the Scala equivalent to javap) and trying to associate the data it provides with Java reflection objects so that I can call methods and such (scalap just parses class files). I found this but there's nothing there... https://github.com/dubochet/scala-reflection ...and I've searched the Scala SVN repo for traces of it and failed to find it there, either (but it could be I just missed it). Does anyone know of a Scala reflection library that provides information similar to what scalap provides but also allows you to call methods, access fields, etc like the Java reflection library?

  • FLEX: customized tag Cloud, how to compute positioning and distances

    - by Patrick
    hi, I want to build a tag cloud like this one in my Flex application. See image: http://dl.dropbox.com/u/72686/tagCloud.png At the moment I have the tags (that are mx.controls.LinkButtons) added at the same position and having different sizes according to values (stored in an ArrayComponent). In my visualization, the orange tags are supposed to be listed vertically in the middle. The gray tags should be at different distances (according to stored numeric values). I want to avoid overlapping and cluttering. How do you suggest to compute x and y of the gray tags taking care about: the distances from orange tags avoid overlapping between them thanks

  • v8 is too slow for my purpose

    - by Scott
    I'm working on a music visualization plugin for libvisual. It's an AVS clone -- AVS being from Winamp. Right now I have a superscope plugin. This element has 4 scripts, and "point" is run at every pixel. You can imagine that it has to be rather fast. The original libvisual avs clone had a JIT compiler that was really fast, but it had some bugs and wasn't fully implemented, so I decided to try v8. Well, v8 is too slow running the compiled script at every pixel. Is there any other script engine that would be pretty fast for this purpose?

  • 3G/Edge/GPRS IP addresses and geocoding

    - by LookitsPuck
    Hey all! So, we're looking to develop a mobile website. On this mobile website, we'd like to automatically populate a user's location (with proper fallback) based on their IP address. I'm aware of geocoding a location based on IP address (mapping to latitude, longitude and then getting the location with that information). However, I'm curious how accurate this information is? Are mobile devices assigned IP's when they utilize 3G, EDGE, and GPRS connections? I think so. If that is so, does it map to a relatively accurate location? It doesn't have to be spot on, but relatively accurate would be nice. Thanks! -Steve

  • API for accessing PHP documentation?

    - by Chad Johnson
    I'm done some Googling, and I've found nothing. I'm scoping out writing a plugin for an editor I use, and I am wondering whether there is a way I can access the PHP documentation via an API? For instance, I'd like to get raw access to the information (besides the comments) located here: http://php.net/file_exists. php.net seemingly uses MediaWiki which provides an API. The tutorial provides the example URL, http://en.wikipedia.org/w/api.php?action=login&format=xml. This does not work for php.net, however (http://php.net/w/api.php?action=login&format=xml). I'm just looking for a little information on how to interface with the PHP documentation.
