  • Getting normal information from OpenGL render output

    - by okamiueru
    I'll try to keep this simple. I want a way to access the normal information of the scene, from the Frame Buffer output (or similar). The same way one is able to access the Depth Buffer using glGetTexImage and GL_DEPTH_COMPONENT. I know I could set up a fragment shader which outputs the normal information in RGB color space, which could in turn be read from the rendered image. I'm wondering however if there is a way to do this within the openGL API. I'll clarify anything upon request as best as I can, Thank you

  • How to get information about a Windows executable (.exe) using C++

    - by ereOn
    Hi, I have to create a software that will scan several directories and extracts information about the executables found. I need to do two things: Determine if a given file is an executable (.exe, .dll, and so on) - Checking the extension is probably not good enough. Get the information about this executable (the company name, the product name, and so on). I never did this before and thus am not aware if there is a Windows API (or lightweight C/C++ library) to do that or if it is even possible. I guess it is, because explorer.exe does it. Do you guys know anything that could point me in the right direction ? Thank you very much for your help.

  • titleForHeaderInSection is not updating Section Header information correctly

    - by Jim
    I have two tableviews where one navigates to the next. Both use more or less the same code and use the managedObjectContext and FetchedResultsController design pattern to provide the relevant data for both tables. My problem happens when I navigate from the first to the second tableview and the data has only one Section Header / Row in the tableview. The data will then not update Section Header information. It does when there is more than one row but not if there is only one row. It leaves the information from the first attempt in place. I can confirm the row data is correct so the relevant data should be being passed to the Section Header correctly but it isn't. Has anyone else come across this problem?

  • Advice on pursuing a masters in information systems or computer science

    - by phantom
    I wanted some advice about pursuing a graduate program. I was recently accepted into a masters in computer science but I do have about 2 years of pre-reqs to complete. However, I attained my undergrad in information systems. I originally applied to computer science because I felt it provided me with more technical knowledge necessary in today's market. I would like to know if you feel four years would be worth it to attain a masters in computer science or spend two years completing attaining a masters in information systems. Thank you! I appreciate your kind response!

  • Save information from MS crash reporter?

    - by DGentry
    On Windows XP when a process crashes, we get a dialog box with a link: "To view technical information about the error report, click here." The "click here" link brings up a whole lot of information in a window, but no obvious way to save it to a file. Is there a way? It would be very nice to be able to send that data to several different external vendors we're working with. The only other option I see in the dialog box is to send it to Microsoft, but this crash is likely not Microsoft's fault and there is no reason to send it to them.

  • providing a java servlet with information

    - by tom
    Hi, i am new to servlets. I made a simple hello world programme that prints those famous 2 words to the screen when i access the page via a browser using http://localhost:8080/mypath/path... My question is now, how do i provide a servlet with information? Specifically considering the fact that my c# programme calculates a lookup value for a global system, then the "java" servlet processes that and returns a set of results. I have done the reverse thanks to help on here, regarding calling a returned string from the java servlet in c#. However i am not sure how i go about providing the servlet information. Do i pass it via the url? Thank you

  • SQL - Link to more table information

    - by BioXhazard
    I have a datagrid with 3 of 5 fields from a SQL table. The first databound was changed to an asp:hyperlink so the field can be clicked. What I want to do is, when the user clicks an object in the field, it sends the ID to another page. From there, it uses the request in order to display the required information which is found in the same SQL table. For example: User clicks on a cell in the first column, it brings them to a page with more information on that cell.

  • Get ffmpeg information in friendly way

    - by JBernardo
    Every time I try to get some information about my video files with ffmpeg, it pukes a lot of useless information mixed with good things. I'm using ffmpeg -i name_of_the_video.mpg. There are any possibilities to get that in a friendly way? I mean JSON would be great (and even ugly XML is fine). By now, I made my application parse the data with regex but there are lots of nasty corners that appear on some specific video files. I fixed all that I encountered, but there may be more. I wanted something like: { "Stream 0": { "type": "Video", "codec": "h264", "resolution": "720x480" }, "Stream 1": { "type": "Audio", "bitrate": "128 kbps", "channels": 2 } }

  • Database Design Question regaurding duplicate information.

    - by galford13x
    I have a database that contains a history of product sales. For example the following table CREATE TABLE SalesHistoryTable ( OrderID, // Order Number Unique to all orders ProductID, // Product ID can be used as a Key to look up product info in another table Price, // Price of the product per unit at the time of the order Quantity, // quantity of the product for the order Total, // total cost of the order for the product. (Price * Quantity) Date, // Date of the order StoreID, // The store that created the Order PRIMARY KEY(OrderID)); The table will eventually have millions of transactions. From this, profiles can be created for products in different geographical regions (based on the StoreID). Creating these profiles can be very time consuming as a database query. For example. SELECT ProductID, StoreID, SUM(Total) AS Total, SUM(Quantity) QTY, SUM(Total)/SUM(Quantity) AS AvgPrice FROM SalesHistoryTable GROUP BY ProductID, StoreID; The above query could be used to get the Information based on products for any particular store. You could then determine which store has sold the most, has made the most money, and on average sells for the most/least. This would be very costly to use as a normal query run anytime. What are some design descisions in order to allow these types of queries to run faster assuming storage size isn’t an issue. For example, I could create another Table with duplicate information. Store ID (Key), Product ID, TotalCost, QTY, AvgPrice And provide a trigger so that when a new order is received, the entry for that store is updated in a new table. The cost for the update is almost nothing. What should be considered when given the above scenario?

  • MPNowPlayingInfoCenter defaultCenter will not update or retrieve information

    - by Jayson Lane
    I'm working to update the MPNowPlayingInfoCenter and having a bit of trouble. I've tried quite a bit to the point where I'm at a loss. The following is my code: self.audioPlayer.allowsAirPlay = NO; Class playingInfoCenter = NSClassFromString(@"MPNowPlayingInfoCenter"); if (playingInfoCenter) { NSMutableDictionary *songInfo = [[NSMutableDictionary alloc] init]; MPMediaItemArtwork *albumArt = [[MPMediaItemArtwork alloc] initWithImage:[UIImage imageNamed:@"series_placeholder"]]; [songInfo setObject:thePodcast.title forKey:MPMediaItemPropertyTitle]; [songInfo setObject:thePodcast.author forKey:MPMediaItemPropertyArtist]; [songInfo setObject:@"NCC" forKey:MPMediaItemPropertyAlbumTitle]; [songInfo setObject:albumArt forKey:MPMediaItemPropertyArtwork]; [[MPNowPlayingInfoCenter defaultCenter] setNowPlayingInfo:songInfo]; } This isn't working, I've also tried: [[MPNowPlayingInfoCenter defaultCenter] setNowPlayingInfo:nil]; In an attempt to get it to remove the existing information from the iPod app (or whatever may have info there). In addition, just to see if I could find out the problem, I've tried retrieving the current information on app launch: NSDictionary *info = [[MPNowPlayingInfoCenter defaultCenter] nowPlayingInfo]; NSString *title = [info valueForKey:MPMediaItemPropertyTitle]; NSString *author = [info valueForKey:MPMediaItemPropertyArtist]; NSLog(@"Currently playing: %@ // %@", title, author); and I get Currently playing: (null) // (null) I've researched this quite a bit and the following articles explain it pretty thoroughly, however, I am still unable to get this working properly. Am I missing something? Would there be anything interfering with this? Is this a service something my app needs to register to access (didn't see this in any docs)? Apple's Docs Change lock screen background audio controls Now playing info ignored UPDATE: I've created a tutorial outlining how I was able to get this functioning properly: http://jaysonlane.net/tech-blog/2012/04/lock-screen-now-playing-with-mpnowplayinginfocenter/

  • ADODB Connection String: Workgroup Information file is Missing?

    - by Mohgeroth
    I have a few data sources in access that I need to connect to programatically to do things with behind the scenes and keep visibility away from users. Said datasource has a password 'pass' as I'm going to call it here. Using this connection method I get an error attempting to use the open method Dim conn as ADODB.Connection Set ROBBERS.conn = New ADODB.Connection conn.open "Provider=Microsoft.Jet.OLEDB.4.0;" _ & "Data Source=\\pep-home\projects\billing\autobilling\DPBilling2.mdb;" _ & "Jet OLEDB:Database Password=pass;", "admin", "pass" "Cannot start your application. The workgroup information file is missing or opened exclusively by another user." Due to planning to move into 2007, we are not using nor have ever used a workgroup identification file through access. The database password on the data source was set through the Set Databa Password which had to be done on an exclusive open. Ive spent a good while changing around my connection options, where to put the passwords etc and either cannot find the right format, or (why I'm asking here) I think there may be some other unknown that I must setup to do this. Anyone out there got some useful information?

  • Get the Information You Need. Delivered.

    - by Get Proactive Customer Adoption Team
    Untitled Document Don’t Take Chances with Alerts—Get Hot Topics When Oracle Support publishes an alert, how do you find out about it? I can see any number of ways you might stumble onto an alert that you need. For example, if you are visiting My Oracle Support in search of answers under the Knowledge tab and happen to notice, and click on, the Alert tab the under the Knowledge Article region, you might see an alert listed for one of the products you use. There are other ways… like subscribing to one of the Oracle Blogs and finding the alert in your RSS feed because the blogger decided to write up that topic for the latest post. I’m sure your colleagues sometimes pass on critical alerts for your products, I hope, giving you the information before you needed it. Well, no matter how you learn about an alert, the important point is that you get the correct information in a timely way. Right? I must admit, the ‘magic’ required to find out via these methods makes me nervous. Rather than leave it to chance, I think you need a more reliable way to stay informed and receive alerts for your products when Oracle publishes them. You may not be aware of it, but there is a better way. Oracle Premier Support Customers can leverage the “Hot Topics E-Mail.” You select the products and topics that interest you. Based on your choices, the system sends you the support related information when Oracle Support publishes it. This way you and I can both relax, knowing you’ll have ready access to the alerts you need, and enjoy the breadth of support related information you choose to subscribe to. This can include recently updated Knowledge base articles, new bugs, and product news. If I’ve convinced you, you will want to know how to set up and subscribe to the Hot Topics E-Mail. The complete guide, Doc ID 793436.1, is waiting for you. Follow the instructions in the document, and you will always stay on top of the latest information from Oracle Support.

  • How to get stack trace information for logging in production when using the GAC

    - by Jonathan Parker
    I would like to get stack trace (file name and line number) information for logging exceptions etc. in a production environment. The DLLs are installed in the GAC. Is there any way to do this? This article says about putting PDB files in the GAC: You can spot these easily because they will say you need to copy the debug symbols (.pdb file) to the GAC. In and of itself, that will not work. I know this article refers to debugging with VS but I thought it might apply to logging the stacktrace also. I've followed the instructions for the answer to this question except for unchecking Optimize code which they said was optional. I copied the dlls and pdbs into the GAC but I'm still not getting the stack trace information. Here's what I get in the log file for the stack trace: OnAuthenticate at offset 161 in file:line:column <filename unknown>:0:0 ValidateUser at offset 427 in file:line:column <filename unknown>:0:0 LogException at offset 218 in file:line:column <filename unknown>:0:0 I'm using NLog. My NLog layout is: layout="${date:format=s}|${level}|${callsite}|${identity}|${message}|${stacktrace:format=Raw}" ${stacktrace:format=Raw} being the relevant part.

  • Sharepoint survey: How to identify the question fields when fetching survey information from the Lis

    - by paul
    I am wanting to access survey information via the Lists web service and display the questions contained in the survey. The result contains a large number of Field nodes some of which are the questions in the survey. The other fields contain other information such as author, last changed etc. How can I pick out the questions? I had thought that all non-questions would be hidden but this is not the case. Here is my code as it is at the moment. It returns about 16 items. The survey has 6 questions... // read question definitions string[] HandleTypes = new string[] { "Number", "DateTime", "Text", "Choice", "GridChoice", "Boolean" }; var query = from n in node.Descendants(ns+"Field") where (n.Attribute("Hidden") == null || n.Attribute("Hidden").Value.ToLower() == "true") && (n.Attribute("Type") != null && HandleTypes.Contains(n.Attribute("Type").Value)) select new Question(n.Attribute("ID").Value) { Text = n.Attribute("DisplayName").Value, QuestionType = n.Attribute("Type").Value, Element = n }; Ideas anyone?

  • Pentaho - Reporting Tool - Is the .prpt file (report template file) contains datasource information

    - by Yatendra Goel
    I am new Pentaho Reporting Tool. I have the following question: When I created a report using Pentaho Report Designer, it output a report file having .prpt extension. After that I found an example on internet where the following code were used to display the report in html format:| protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { ResourceManager manager = new ResourceManager(); manager.registerDefaults(); String reportPath = "file:" + this.getServletContext().getRealPath("sampleReport.prpt"); try { Resource res = manager.createDirectly(new URL(reportPath), MasterReport.class); MasterReport report = (MasterReport) res.getResource(); HtmlReportUtil.createStreamHTML(report, response.getOutputStream()); } catch (Exception e) { e.printStackTrace(); } } And the report got printed successfully. So as we haven't specified any datasource information here, I think that the .prpt file contains that information in it. If that's true than Isn't Jasper is better Reporting tool than Pentaho because when we display Jasper reports, we have to provide datasource details also so in that way our report is flexible and is not bound to any particular database.

  • Extend base type and automatically update audit information on Entity

    - by Nix
    I have an entity model that has audit information on every table (50+ tables) CreateDate CreateUser UpdateDate UpdateUser Currently we are programatically updating audit information. Ex: if(changed){ entity.UpdatedOn = DateTime.Now; entity.UpdatedBy = Environment.UserName; context.SaveChanges(); } But I am looking for a more automated solution. During save changes, if an entity is created/updated I would like to automatically update these fields before sending them to the database for storage. Any suggestion on how i could do this? I would prefer to not do any reflection, so using a text template is not out of the question. A solution has been proposed to override SaveChanges and do it there, but in order to achieve this i would either have to use reflection (in which I don't want to do ) or derive a base class. Assuming i go down this route how would I achieve this? For example EXAMPLE_DB_TABLE CODE NAME --Audit Tables CREATE_DATE CREATE_USER UPDATE_DATE UPDATE_USER And if i create a base class public abstract class IUpdatable{ public virtual DateTime CreateDate {set;} public virtual string CreateUser { set;} public virtual DateTime UpdateDate { set;} public virtual string UpdateUser { set;} } The end goal is to be able to do something like... public overrride void SaveChanges(){ //Go through state manager and update audit infromation //FOREACH changed entity in state manager if(entity is IUpdatable){ //If state is created... update create audit. //if state is updated... update update audit } } But I am not sure how I go about generating the code that would extend the interface.

  • Mac OS X: Getting detailed process information (specifically its launch arguments) for arbitrary run

    - by Jasarien
    I am trying to detect when particular applications are launched. Currently I am using NSWorkspace, registering for the "did launch application" notification. I also use the runningApplications method to get apps that are currently running when my app starts. For most apps, the name of the app bundle is enough. I have a plist of "known apps" that I cross check with the name of that passed in the notification. This works fine until you come across an app that acts as a proxy for launching another application using command line arguments. Example: The newly released Portal on the Mac doesn't have a dedicated app bundle. Steam can create a shortcut, which serves as nothing more than to launch the hl2_osx app with the -game argument and portal as it's parameter. Since more Source based games are heading to the Mac, I imagine they'll use the same method to launch, effectively running the hl2_osx app with the -game argument. Is there a nice way to get a list of the arguments (and their parameters) using a Cocoa API? NSProcessInfo comes close, offering an `-arguments' method, but only provides information for its own process... NSRunningApplication offers the ability to get information about arbitrary apps using a PID, but no command line args... Is there anything that fills the gap between the two? I'm trying not to go down the route of spawning an NSTask to run ps -p [pid] and parsing the output... I'd prefer something more high level.

  • (rsErrorOpeningConnection) Could not obtain information about Windows NT group/user

    - by ChelleATL
    I am trying to deploy a report to the Reporting Services Server but keep running up against this error: An error occurred during client rendering. An error has occurred during report processing. (rsProcessingAborted) Cannot create a connection to data source 'dataSource1'. (rsErrorOpeningConnection) Could not obtain information about Windows NT group/user 'DOMAIN\useradmin', error code 0x5. Here’s my situation: Everything is being ran using DOMAIN\useradmin and the report is using a remote database. Reporting Services and SQL Server are both ran under DOMAIN\useradmin. DOMAIN\useradmin is a windows AD login and is part of the server machine Administrators group. My test report is using a data source model that in turn is using a data source that is connection to a database on a different SQL Server. The data source is using “Credentials stored securely in the report server” with the options “Use as Windows credentials when connecting to the data source” and “Impersonate the authenticated user after a connection has been made to the data source.” I am using the credentials of DOMAIN\useradmin that is the db owner of the remote database. DOMAIN\useradmin is assigned the roles, System Administrator, System User and Browser, Content Manager, My Reports, Publisher, Report Builder. So if everything is being run under an über AD account, why I am getting this Could not obtain information about Windows NT group/user 'DOMAIN\useradmin' error? Under normal circumstances , an AD login with Publisher permissions will developing reports using a datasource model created by DOMAIN\useradmin but using one of the remote database’s users which is mapped from yet another AD login. I ran the following statements and non errors were returned: use master go xp_grantlogin 'DOMAIN\useradmin' go xp_logininfo 'DOMAIN\useradmin' go

  • iphone crash log with dSym not loading debug information

    - by AngeDeLaMort
    Hello, I was trying to see why my application crashed on the device (iPhone) using the dSym generated along the executable (in ad hoc), but I don't know why, there isn't any useful information. It seems that "Organizer" is able to find the appropriate dSym and translate some data into more readable one, but when it comes to my application, I just have an address. Since I know how to reproduce it, I've tried to setup my build so it can help me in the future. So, I've tried to find if I had all the proper flags set int the project build properties and everything seems fine. So after doing some research, it seems that all information are stripped during link time and the dSym seems completely useless. I've played with some flags, but nothing changed. So, is there something special to do in order to get the crash file human readable? Or is it impossible in the ad hoc setting? The closest thing near to work that I've done was to build a debug version and look up the address in it. At least it seems to give the right file. So, I made a sample app and here what I have: (the line I want is #4): Thread 0 Crashed: 0 libobjc.A.dylib 0x00003ebc objc_msgSend + 20 1 UIKit 0x0005c970 -[UIView dealloc] + 60 2 UIKit 0x0005c840 -[UIImageView dealloc] + 76 3 CoreFoundation 0x0003963a -[NSObject release] + 28 4 MyApplication 0x000046a6 0x1000 + 13990 5 UIKit 0x00069750 -[UIViewController view] + 44 6 MyApplication 0x000053fa 0x1000 + 17402 The crash is made using 2 successive releases on an object. Thanks in advance.

  • retrieving object information with Doctrine

    - by ajsie
    i want to fetch information from the database using objects. i really like this approach cause this is more OOP: $user = Doctrine_Core::getTable('User')->find(1); echo $user->Email['address']; echo $user->Phonenumbers[0]->phonenumber; rather than: $q = Doctrine_Query::create() ->from('User u') ->leftJoin('u.Email e') ->leftJoin('u.Phonenumbers p') ->where('u.id = ?', 1); $user = $q->fetchOne(); echo $user->Email['address']; echo $user->Phonenumbers[0]['phonenumber']; the problem is that the first one uses 3 queries (3 different tables), while the second one uses only 1 (and is therefore recommended technique). but i feel that it destroys the object oriented design. cause ORM is meant to give us an OOP approach so that we could focus on objects and not the relational database. but now they want us to go back to use SQL like pattern. there isn't a way to get information form multiple tables not using DQL? the above examples are taken from the documentation: doctrine
