  • Creating a directory in linux assembly language

    - by Jayson Kane
    I am trying to create a small assembly program to create a folder. I looked up the system call for creating a directory on this page: http://www.ctyme.com/intr/rb-8144.htm It says that it is identified by 27h. How would I go about implementing the "mkdir somename" in assembly? I am aware that the program should move 27 into eax but I am unsure where to go next. I have googled quite a bit and no one seems to have posted anthing about this online. This is my current code (I don't know in which register to put filename and so on) section .data section .text global _start mov eax, 27 mov ???????? .... int 80h Thanks

  • Hibernate: @UniqueConstraint with @ManyToOne field???

    - by Misha Koshelev
    Dear All: Using the following code: @Entity @Table(uniqueConstraints=[@UniqueConstraint(columnNames=["account","name"])]) class Friend { @Id @GeneratedValue(strategy=GenerationType.AUTO) public Long id @ManyToOne public Account account public String href public String name } I get the following error: org.hibernate.AnnotationException: Unable to create unique key constraint (account, name) on table Friend: account not found It seems this has to do with the @ManyToOne constraint, which I imagine actually creates a separate UniqueConstraint??? In any case, if I take this out, there is no complaint about the UniqueConstraint, but there is another error which makes me believe it must be left in. org.hibernate.MappingException: Could not determine type for: com.mksoft.fbautomate.domain.Account, at table: Friend, for columns: [org.hibernate.mapping.Column(account)] Any hints how I can create such a desired constraint (i.e., that each combination of account and name occurs only once???) Thank you! Misha

  • attaching linq to sql datacontext to httpcontext in business layer

    - by rap-uvic
    Hello all, I need my linq to sql datacontext to be available across my business/data layer for all my repository objects to access. However since this is a web app, I want to create and destroy it per request. I'm wondering if having a singleton class that can lazily create and attach the datacontext to current HttpContext would work. My question is: would the datacontext get disposed automatically when the request ends? Below is the code for what I'm thinking. Would this accomplish my purpose: have a thread-safe datacontext instance that is lazily available and is automatically disposed when the request ends? public class SingletonDC { public static NorthwindDataContext Default { get { NorthwindDataContext defaultInstance = (NorthwindDataContext)System.Web.HttpContext.Current.Items["datacontext"]; if (defaultInstance == null) { defaultInstance = new NorthwindDataContext(); System.Web.HttpContext.Current.Items.Add("datacontext", defaultInstance); } return defaultInstance; } } }

  • constructors and inheritance in JS

    - by nandinga
    Hi all, This is about "inheritance" in JavaScript. Supose I create a constructor Bird(), and another called Parrot() which I make to "inherit" the props of Bird by asigning an instance of it to Parrot's prototype, like the following code shows: function Bird() { this.fly = function(){}; } function Parrot() { this.talk = function(){ alert("praa!!"); }; } Parrot.prototype = new Bird(); var p = new Parrot(); p.talk(); // Alerts "praa!!" alert(p.constructor); // Alerts the Bird function!?!?! After I've created an instance of Parrot, how comes that the .constructor property of it is Bird(), and not Parrot(), which is the constructor I've used to create the object? Thanks!!

  • Linq to xml not able to add new elements

    - by Fore
    We save our xml in a "text" field in the database. So first I check if it exist any xml, if not I create a new xdocument, fill it with the necessary xml. else i just add the new element. Code looks like this: XDocument doc = null; if (item.xmlString == null || item.xmlString == "") { doc = new XDocument(new XDeclaration("1.0", "utf-8", "yes"), new XElement("DataTalk", new XAttribute(XNamespace.Xmlns + "xsi", "http://www.w3.org/2001/XMLSchema-instance"), new XAttribute(XNamespace.Xmlns + "xsd", "http://www.w3.org/2001/XMLSchema"), new XElement("Posts", new XElement("TalkPost")))); } else { doc = XDocument.Parse(item.xmlString); } This is working alright to create a structure, but then the problem appears, when I want to add new TalkPost. I get an error saying incorrectly structured document. The following code when adding new elements: doc.Add(new XElement("TalkPost", new XElement("PostType", newDialog.PostType), new XElement("User", newDialog.User), new XElement("Customer", newDialog.Customer), new XElement("PostedDate", newDialog.PostDate), new XElement("Message", newDialog.Message)));

  • Creating Membership Tables, SPROCs, Views in Attached DB

    - by azamsharp
    I have AdventureWorks database mdf file in my VS 2010 project. Is there anyway I can create Membership tables inside my AdventureWorks database. I know I can detach the database attach in SQL SERVER 2008. Create the tables and then detach. But I don't have SQL SERVER 2008 and I want to see if this can be done using command line tool. I tried this but no use: aspnet_regsql.exe -d AdventureWorks.mdf -A mr -E -S .\SQLEXPRESS Update: If I right click and see the properties of the AdventureWorks.mdf database then it shows the name as "C4BE6C8DA139A060D14925377A7E63D0_64A_10\ADVENTUREWORKSWEBFORMS\ADVENTUREWORKSWEBFORMS\ADVENTUREWORKS\APP_DATA\ADVENTUREWORKS.MDF" This is interesting!

  • .NET connecting with RDP

    - by user311130
    I want to connect to a remote desktop connection to a specified server/username from c#. I have found: __http://www.codeproject.com/KB/cs/RemoteDesktop_CSharpNET.aspx a AxMSTSCLib dll should be referenced to the solution. I don't want to download this dll from anywhere as I'm not sure if I can trust it. However it also says: "After research on the web I found that I have to create new AxMSTSCLib and MSTSCLib DLLs. So I did" How do I "create" this new AxMSTSCLib ? Other link, doesn't use this dll but run an script instead. http://bytes.com/topic/c-sharp/answers/517024-remote-desktop-connection-c but that code throws Security Exception. So I cannot use it.

  • PPP connection with RAS dialer in C++

    - by user312054
    I have a windows mobile application that is using Windows CE 5.0. I have been informed by the people supplying the hardware for the unit that I need to create a socket, which I have done successfully, and then dial out to the internet with a PPP connection with a RAS dialer connection. Our old code uses an APN to dial out so I need to create the above connection with an APN. I am having trouble finding examples of this. Can someone point me to some examples of this situation?

    - by Jonas
    I have setup Riak on a Ubuntu machine, and it seam to work if I do riak ping. Now I would like to use the Riak Java client to store an object, but it doesn't work.

  • Creating GUI using XML file in C#

    - by Gal Goldman
    How can I create automatic GUI using XML file in C#? Should I write a parser for the file and define a sort of "protocol" for the file's structure, and after the parse - create the GUI controls manually (respective to the data in the files)? Or is there a better way? Is there a tool, or a built-in code in the .NET environment which can do that for me automatically? (I am currently working with win forms, but I am willing to consider any other technology - as long as it's supported in MONO, since the code should be portable to Linux as well).

  • How to navigate clicking row to another UITableView ?

    - by Meko
    Hi. I am trying to show detailed UItable view when clicking on row. I used - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { // Navigation logic may go here. Create and push another view controller. // AnotherViewController *anotherViewController = [[AnotherViewController alloc] initWithNibName:@"AnotherView" bundle:nil]; photoListViewController = [[PhotoListViewController alloc]initWithNibName:@"PhotoListViewController" bundle:[NSBundle mainBundle]]; [self.navigationController pushViewController:photoListViewController animated:YES]; [photoListViewController release]; // [self.navigationController pushViewController:anotherViewController]; // [anotherViewController release]; } This PhotoListViewController is an empty UITableViewController. As I know UITableViewCOntroller has a navigation controller implemented and I don`t have to create navigation controller. But When I clicked on row it does not navigate to second view.AM I have to make some connection on nib file?I only created this PhotoListViewController in File-New-UIViewCOntroller and selected UITableView. EDIT : SOLVED I solved my problem.I should use UINAvigation object.I thought that UITable has it but there was no ))

  • user table with javaDB and hybernate from within grails

    - by Ralf
    let's see if I can ask this in an understandable way... I started with grails and created a domain class called user. As far as I understand, hybernate is used to map this domain class to the database. This works pretty fine with hsqldb. Now I tried to switch to javaDB and get an error message because the table is called "user" (which seems to be a reserverd word for javaDB). So a statement like create table user ... will result in an error message. create table "user" ... works, but hybernate seems not put put the table name in quotes. How can I configure hybernate to use quotes in order to make it work with my table name? PS: yes, I know, I could map the domain class to another table name... :-)

  • Creating a Box Control over an area of the map with OpenLayers

    - by Bernie Perez
    I am using OpenLayers to create a box of interest with my program. I am using this code: var control = new OpenLayers.Control(); OpenLayers.Util.extend(control, { draw: function () { this.box = new OpenLayers.Handler.Box( control, {"done": this.notice}, {keyMask: OpenLayers.Handler.MOD_SHIFT}); this.box.activate(); }, notice: function (bounds) { areaSelected(bounds); } }); map.addControl(control); to capture the "Shift Create a Box" control and use the area selected as my area of interest. However the values come back as pixels. But I want Longitude and Latitude, not pixels. The Mouse Position control does show the correct long & lat. I really don't care how to box is created, I just want an easy way for the user to select a area of the map and I need to get the lat & longs of the area. (Box, Circle, doesn't matter)

I am using a tutorial to accomplish this http://www.tonymarston.net/php-mysql/dom.html#a5 what I want to do is to create each element separately, instead of creating them all at once as shown in the tutorial. In order to do that I am trying to place the specific field name into the foreach loop below, any help would be greatly appreciated. foreach ($row as where fieldname should go => $row['artistname']) { $artval = $doc->createTextNode($row['artistname']); $artval = $chil->appendChild($val); }

  • Automate Testing on future only items business rules

    - by Titan
    I currently have a business object with a validation business rule, which is it can only be created for the future, tomorrow onwards, and I cannot create new items for today. I have a process, which runs the non-future business objects through some steps.. Because I have to set things up today, and test tomorrow, and when it fails, I can only create a new object tomorrow and test the following day. Are there any easy ways to automate this process in any testing frameworks? I think our testers are using the visual studio 2010 test manager. How do you guys manage situations like this? Cheers

  • C# to loop through folder until it finds the correct files

    - by Liton Uddin
    I’m running a batch to do an update to my sql table. I’m using windows scheduler to run the batch file. Each day files come in at different time. Sometime they come in after my scheduled time therefore the batch file doesn’t run when there’s no file before the scheduled task in the folder. I want to create a c# program where it will loop through the folder until it finds the files and then move to the next step in the batch file. Basically my goal is to create a program that will look for those particular files and once they finds the correct files then it will start the update. I’m new to programming and need some direction. Can someone please help me with this? Thanks.

  • Making a DVD video with a still image and PCM 16bit audio with ffmpeg

    - by João
    I'm trying to make a small video with a still image and a sound file playing in the background to pass it to dvdauthor and create a DVD. The command I'm using is this: ffmpeg -loop_input -i image.jpg -qscale 2 -i song.flac -aspect 4:3 -target pal-dvd -acodec pcm_s16le -shortest output.mpg However, the resulting video file doesn't have sound at all (testing it on VLC Player). I don't know if I can't combine "-acodec pcm_s16le" with "-target pal-dvd" to override the later, or if there is something else wrong with the command. If I try without the "-acodec pcm_s16le" parameter the video and audio works, I can even create a DVD ISO with it. However, the audio stays as AC3. I wanted to include with the video the lossless audio, not a compressed one. I suppose the DVD standart allows to have PCM audio in it, am I right?

  • Subcontrols not visible in custom control derived from another control

    - by Gacek
    I'm trying to create a custom control by deriving from a ZedGraphControl I need to add a ProgressBar to the control, but I encountered some problems. When I create a custom control and add both, ZedGraphCOntrol and ProgressBar to it, everything is OK: MyCustomControl { ZedGraphControl ProgressBar } All elemnets are visible and working as expected. But I need to derive from ZGC and when I add a progress bar as a subcontrol of ZedGraphControl: MyCustomControl : ZedGRaphControl { ProgressBar } The progress bar is not visible. Is there any way to force the visibility of ProgressBar? Is it possible, that ZedGraphControl is not displaying its subcontrols? I tried do the same thing with a simple button and it's also not being displayed.

  • How important is W3C XHTML/CSS validation when finalizing work?

    - by Andrew G. Johnson
    Even though I always strive for complete validation these days, I often wonder if it's a waste of time. If the code runs and it looks the same in all browsers (I use browsershots.org to verify) then do I need to take it any further or am I just being overly anal? What level do you hold your code to when you create it for: a) yourself b) your clients P.S. Jeff and company, why doesn't stack overflow validate? :) EDIT: Some good insights, I think that since I've been so valid-obsessed for so long I program knowing what will cause problems and what won't so I'm in a better position than people who create a site first and then "go back and fix the validation problems" I think I may post another question on stack overflow; "Do you validate as you go or do you finish and then go back and validate?" as that seems to be where this question is going
