  • Configuring network to set wlan0 as primary

    - by Sheed
    I recently had to rebuild my pc and decided to go for ubuntu 14.04. I think the mistake I made was I started from a 12.04 install disk instead of the 12.10 disk I'd used previously and when given the option set my primary connection as ethernet (because the wireless option didn't work). After upgrading to 14.04 etc, I managed to get the wireless working, or more using steps like ifconfig -a and the likes I managed to prove that the wireless card etc. is all installed and working. However every time I boot without a hard wired connection plugged in I get the message "waiting for network configuration". I can then once it's booted without a network get my wirless working using sudo ifconfig wlan0 up iwlist wlan0 scan This seems to kick the wireless module into life and it appears in the GUI and I can then select a network, however all the options like edit network and disconnect etc are all greyed out. What I would like of course is if the WLAN0 was just set as my primary default network so I've been looking for a solution to this and it would seem that I need to adjust the old /etc/network/interfaces file but when I try to do so using the sudo vi /etc/network/interfaces command I, well I simply have no idea what I'm doing. Other than that typing :q! gets me out of there before I do to much damage! As far as I can tell (by navigating to the file in the GUI) the output of my /etc/network/interfaces is as follows: (obviously not including the " in each line that's just to break the heading rule of the #) "# This file describes the network interfaces available on your system "# and how to activate them. For more information, see interfaces(5). "# The loopback network interface auto lo iface lo inet loopback "# The primary network interface auto eth0 iface eth0 inet dhcp If this is the case then this clearly doesn't contain what it should do but I don't how to fix it. Nor do I even know if I'm on the right track. Any help would be appreciated thanks :)

  • Learning project Custom c# Cms [closed]

    - by user313378
    I want to start new project customCms, cause I think it's a good starting point to implement my collected knowledge from c#, ddd, nhibernate, mvc3, js. It will be great if I hear some guidlines from expirienced users here. I will use C# ASP.NET MVC3 razor view engine. Also I was thinking of NHibernate ORM, I dont know if using Nhibernate will cause performanse down. Initially MSSQL 2008 will be used, but using ORM layer cause that I can switch to some other db with no pain. I was thinking to create News entity which will have properties Id Name Created Updated IntroText Content Title Author ListPhotos Every input will be validated with untroub. java script on the view, and it will be validated on db level as well. Maybe it is best approach to create some interface which will be implemented by my cmsClient entity like NewsEntity. In this interface will be included everything it should be requested from my client in future. At least some stuff which are not included in entity right now, consumed data by rss feed, wcf, etc. So basically everything you think its good idea from documentating project, to coding. Everyone is welcomed to brainstorm for custom cms.

  • Alternatives to PHP [closed]

    - by kaz
    We are starting a project, which goal is to create new frontend interface to our product. Old version was created in PHP, very poorly written. We are choosing the language and frameworks that we want to use in new version. Requirements: New interface will be communicating with API. Application will not have it's own database. We don't have a big team, 3 max programmers for entire project. The main programmers are PHP veterans and knows some other technologies (Rails, C, C++, some Java) but not in professional level. But overall they are good and experienced programmers. So: We want to find a good alternative to PHP. I like Rails very much, but whole ActiveRecord model will be useless, when using application API. Java needs a lot of configuration and someone who is expert in Java to properly run this project. Also, in Java there are a lot of big and complicated enterprise frameworks - not very good for 2-3 programmers team. Python - I don't know Python and don't know good and experienced programmers who knows PY - but it's not so complicated and big as Java and maybe in long period it's good alternative for PHP. What are your thoughts?

  • How to take the snapshot of a IE webpage through a BHO (C#)

    - by Kapil
    Hi, I am trying to build an IE BHO in C# for taking the snapshot of a webpage loaded in the IE browser. Here is what I'm trying to do: public class ShowToolbarBHO : BandObjectLib.IObjectWithSite { IWebBrowser2 webBrowser = null; public void SetSite (Object site) { ....... if (site != null) { ...... webBrowser = (IWebBrowser2)site; ...... } } } Also, I p/invoke the following COM methods: [Guid("0000010D-0000-0000-C000-000000000046")] [InterfaceTypeAttribute(ComInterfaceType.InterfaceIsIUnknown)] [ComImportAttribute()] public interface IViewObject { void Draw([MarshalAs(UnmanagedType.U4)] int dwDrawAspect, int lindex, IntPtr pvAspect, [In] IntPtr ptd, IntPtr hdcTargetDev, IntPtr hdcDraw, [MarshalAs(UnmanagedType.LPStruct)] ref COMRECT lprcBounds, [In] IntPtr lprcWBounds, IntPtr pfnContinue, int dwContinue); int GetColorSet([MarshalAs(UnmanagedType.U4)] int dwDrawAspect, int lindex, IntPtr pvAspect, [In] IntPtr ptd, IntPtr hicTargetDev, [Out] IntPtr ppColorSet); int Freeze([MarshalAs(UnmanagedType.U4)] int dwDrawAspect, int lindex, IntPtr pvAspect, out IntPtr pdwFreeze); int Unfreeze([MarshalAs(UnmanagedType.U4)] int dwFreeze); int SetAdvise([MarshalAs(UnmanagedType.U4)] int aspects, [MarshalAs(UnmanagedType.U4)] int advf, [MarshalAs(UnmanagedType.Interface)] IAdviseSink pAdvSink); void GetAdvise([MarshalAs(UnmanagedType.LPArray)] out int[] paspects, [MarshalAs(UnmanagedType.LPArray)] out int[] advf, [MarshalAs(UnmanagedType.LPArray)] out IAdviseSink[] pAdvSink); } [StructLayoutAttribute(LayoutKind.Sequential)] public class COMRECT { public int left; public int top; public int right; public int bottom; public COMRECT() { } public COMRECT(int left, int top, int right, int bottom) { this.left = left; this.top = top; this.right = right; this.bottom = bottom; } } [InterfaceTypeAttribute(ComInterfaceType.InterfaceIsIUnknown)] [ComVisibleAttribute(true)] [GuidAttribute("0000010F-0000-0000-C000-000000000046")] [ComImportAttribute()] public interface IAdviseSink { void OnDataChange([In]IntPtr pFormatetc, [In]IntPtr pStgmed); void OnViewChange([MarshalAs(UnmanagedType.U4)] int dwAspect, [MarshalAs(UnmanagedType.I4)] int lindex); void OnRename([MarshalAs(UnmanagedType.Interface)] object pmk); void OnSave(); void OnClose(); } Now When I take the snapshot: I make a call CaptureWebScreenImage((IHTMLDocument2) webBrowser.document); public static Image CaptureWebScreenImage(IHTMLDocument2 myDoc) { int heightsize = (int)getDocumentAttribute(myDoc, "scrollHeight"); int widthsize = (int)getDocumentAttribute(myDoc, "scrollWidth"); Bitmap finalImage = new Bitmap(widthsize, heightsize); Graphics gFinal = Graphics.FromImage(finalImage); COMRECT rect = new COMRECT(); rect.left = 0; rect.top = 0; rect.right = widthsize; rect.bottom = heightsize; IntPtr hDC = gFinal.GetHdc(); IViewObject vO = myDoc as IViewObject; vO.Draw(1, -1, (IntPtr)0, (IntPtr)0, (IntPtr)0, (IntPtr)hDC, ref rect, (IntPtr)0, (IntPtr)0, 0); gFinal.ReleaseHdc(); gFinal.Dispose(); return finalImage; } I am not getting the image of the webpage. Rather I am getting an image with black background. I am not sure if this is the right way of doing it, but I found over the web that IViewObject::Draw method is used for taking the image of a webpage in IE. I was earlier doing the image capture using the Native PrintWindow() method as mentioned in the following codeproject's page - http://www.codeproject.com/KB/graphics/IECapture.aspx But the image size is humongous! I was trying to see if I can reduce the size by using other techniques. It would be great if someone can point out the mistakes (I am sure there would be many) in my code above. Thanks, Kapil

  • Is Multicast broken for Android 2.0.1 (currently on the DROID) or am I missing something?

    - by Gubatron
    This code works perfectly in Ubuntu, in Windows and MacOSX, it also works fine with a Nexus-One currently running firmware 2.1.1. I start sending and listening multicast datagrams, and all the computers and the Nexus-One will see each other perfectly. Then I run the same code on a Droid (Firmware 2.0.1), and everybody will get the packets sent by the Droid, but the droid will listen only to it's own packets. This is the run() method of a thread that's constantly listening on a Multicast group for incoming packets sent to that group. I'm running my tests on a local network where I have multicast support enabled in the router. My goal is to have devices meet each other as they come on line by broadcasting packages to a multicast group. public void run() { byte[] buffer = new byte[65535]; DatagramPacket dp = new DatagramPacket(buffer, buffer.length); try{ MulticastSocket ms = new MulticastSocket(_port); ms.setNetworkInterface(_ni); //non loopback network interface passed ms.joinGroup(_ia); //the multicast address, currently 224.0.1.16 Log.v(TAG,"Joined Group " + _ia); while (true) { ms.receive(dp); String s = new String(dp.getData(),0,dp.getLength()); Log.v(TAG,"Received Package on "+ _ni.getName() +": " + s); Message m = new Message(); Bundle b = new Bundle(); b.putString("event", "Listener ("+_ni.getName()+"): \"" + s + "\""); m.setData(b); dispatchMessage(m); //send to ui thread } } catch (SocketException se) { System.err.println(se); } catch (IOException ie) { System.err.println(ie); } } Over here, is the code that sends the Multicast Datagram out of every valid network interface available (that's not the loopback interface). public void sendPing() { MulticastSocket ms = null; try { ms = new MulticastSocket(_port); ms.setTimeToLive(TTL_GLOBAL); List<NetworkInterface> interfaces = getMulticastNonLoopbackNetworkInterfaces(); for (NetworkInterface iface : interfaces) { //skip loopback if (iface.getName().equals("lo")) continue; ms.setNetworkInterface(iface); _buffer = ("FW-"+ _name +" PING ("+iface.getName()+":"+iface.getInetAddresses().nextElement()+")").getBytes(); DatagramPacket dp = new DatagramPacket(_buffer, _buffer.length,_ia,_port); ms.send(dp); Log.v(TAG,"Announcer: Sent packet - " + new String(_buffer) + " from " + iface.getDisplayName()); } } catch (IOException e) { e.printStackTrace(); } catch (Exception e2) { e2.printStackTrace(); } } Update (April 2nd 2010) I found a way to have the Droid's network interface to communicate using Multicast! _wifiMulticastLock = ((WifiManager) context.getSystemService(Context.WIFI_SERVICE)).createMulticastLock("multicastLockNameHere"); _wifiMulticastLock.acquire(); Then when you're done... if (_wifiMulticastLock != null && _wifiMulticastLock.isHeld()) _wifiMulticastLock.release(); After I did this, the Droid started sending and receiving UDP Datagrams on a Multicast group. gubatron

  • How to have two UIPickerViews together in one ViewController?

    - by 0SX
    I'm trying to put 2 UIPickerViews together in one ViewController. Each UIPickerView has different data arrays. I'm using interface builder to link the pickers up. I know I'll have to use separate delegates and dataSources but I can't seem to hook everything up with interface builder correctly. Here's all my code: pickerTesting.h #import <UIKit/UIKit.h> #import "picker2DataSource.h" @interface pickerTestingViewController : UIViewController <UIPickerViewDelegate, UIPickerViewDataSource>{ IBOutlet UIPickerView *picker; IBOutlet UIPickerView *picker2; NSMutableArray *pickerViewArray; } @property (nonatomic, retain) IBOutlet UIPickerView *picker; @property (nonatomic, retain) IBOutlet UIPickerView *picker2; @property (nonatomic, retain) NSMutableArray *pickerViewArray; @end pickerTesting.m #import "pickerTestingViewController.h" @implementation pickerTestingViewController @synthesize picker, picker2, pickerViewArray; - (void)viewDidLoad { [super viewDidLoad]; pickerViewArray = [[NSMutableArray alloc] init]; [pickerViewArray addObject:@" 100 "]; [pickerViewArray addObject:@" 200 "]; [pickerViewArray addObject:@" 400 "]; [pickerViewArray addObject:@" 600 "]; [pickerViewArray addObject:@" 1000 "]; [picker selectRow:1 inComponent:0 animated:NO]; picker2.delegate = self; picker2.dataSource = self; } - (NSInteger)numberOfComponentsInPickerView:(UIPickerView *)picker; { return 1; } - (void)pickerView:(UIPickerView *)picker didSelectRow:(NSInteger)row inComponent:(NSInteger)component { } - (NSInteger)pickerView:(UIPickerView *)picker numberOfRowsInComponent:(NSInteger)component; { return [pickerViewArray count]; } - (NSString *)pickerView:(UIPickerView *)picker titleForRow:(NSInteger)row forComponent:(NSInteger)component; { return [pickerViewArray objectAtIndex:row]; } - (void)didReceiveMemoryWarning { // Releases the view if it doesn't have a superview. [super didReceiveMemoryWarning]; // Release any cached data, images, etc that aren't in use. } - (void)viewDidUnload { // Release any retained subviews of the main view. // e.g. self.myOutlet = nil; } - (void)dealloc { [super dealloc]; } @end And I have a separate class for the other datasource. picker2DataSource.h @interface picker2DataSource : NSObject <UIPickerViewDataSource, UIPickerViewDelegate> { NSMutableArray *customPickerArray; } @property (nonatomic, retain) NSMutableArray *customPickerArray; @end picker2DataSource.m #import "picker2DataSource.h" @implementation picker2DataSource @synthesize customPickerArray; - (id)init { // use predetermined frame size self = [super init]; if (self) { customPickerArray = [[NSMutableArray alloc] init]; [customPickerArray addObject:@" a "]; [customPickerArray addObject:@" b "]; [customPickerArray addObject:@" c "]; [customPickerArray addObject:@" d "]; [customPickerArray addObject:@" e "]; } return self; } - (void)dealloc { [customPickerArray release]; [super dealloc]; } - (NSInteger)numberOfComponentsInPickerView:(UIPickerView *)picker2; { return 1; } - (void)pickerView:(UIPickerView *)picker2 didSelectRow:(NSInteger)row inComponent:(NSInteger)component { } - (NSInteger)pickerView:(UIPickerView *)picker2 numberOfRowsInComponent:(NSInteger)component; { return [customPickerArray count]; } - (NSString *)pickerView:(UIPickerView *)picker2 titleForRow:(NSInteger)row forComponent:(NSInteger)component; { return [customPickerArray objectAtIndex:row]; } @end Any help or code examples would be great.

  • Duplex Contract GetCallbackChannel always returns a null-instance

  • If 'Architect' is a dirty word - what's the alternative; when not everyone can actually design a goo

    - by Andras Zoltan
    Now - I'm a developer first and foremost; but whenever I sit down to work on a big project with lots of interlinking components and areas, I will forward-plan my interfaces, base classes etc as best I can - putting on my Architect hat. For a few weeks I've been doing this for a huge project - designing whole swathes of interfaces etc for a business-wide platform that we're developing. The basic structure is a couple of big projects that consists of service and data interfaces, with some basic implementations of all of these. On their own, these assemblies are useless though, as they are simply intended intended as a scaffold on which to build a business-specific implementation (we have a lot of businesses). Therefore, the design of the core platform is absolutely crucial, since consumers of the system are not intended to know which implementation they are actually using. In the past it's not worked so well, but after a few proof-of-concepts and R&D projects this new platform is now growing nicely and is already proving itself. Then somebody else gets involved in the project - he's a TDD man who sees code-level architecture as an irrelevance and is definitely from the camp that 'architect' is a dirty word - I should add that our working relationship is very good despite this :) He's open about the fact that he can't architect in advance and obviously TDD really helps him because it allows him to evolve his systems over time. That I get, and totally understand; but it means that his coding style, basically, doesn't seem to be able to honour the architecture that I've been putting in place. Now don't get me wrong - he's an awesome coder; but the other day he needed to extend one of his components (an implementation of a core interface) to bring in an extra implementation-specific dependency; and in doing so he extended the core interface as well as his implementation (he uses ReSharper), thus breaking the independence of the whole interface. When I pointed out his error to him, he was dismayed. Being test-first, all that mattered to him was that he'd made his tests pass, and just said 'well, I need that dependency, so can't we put it in?'. Of course we could put it in, but I was frustrated that he couldn't see that refactoring the generic interface to incorporate an implementation-specific feature was just wrong! But it is all very Charlie Brown to him (you know the sound the adults make when they're talking to the children) - as far as he's concerned we don't need to worry about it because we can always refactor. The problem is, the culture of test-write-refactor is all very well and good - but not when you're dealing with a platform that is going to be shared out among so many projects that you could never get them all in one place to make the refactorings work. In my opinion, sometimes you actually have to think about what you're doing, and not just let nature take its course. Am I simply fulfilling the role of Architect as a dirty word here? I believe that architecture is important and should be thought about before code gets written; unless it's a particularly small project. But when you're working in a team of people who don't think that way, or even can't think that way how can you actually get this across? Is it a case of simply making the architecture off-limits to changes by other people? I don't want to start having bloody committees just to be able to grow the system; but equally I don't want to be the only one responsible for it all. Do you think the architect role is a waste of time? Is it at odds with TDD and other practises? Can this mix of different practises be made to work, or should I just be a lot less precious (and in so doing allow a generic platform become useless!)? Or do I just lay down the law? Any ideas/experiences/views gratefully received.

  • ASP.NET how to implement IServiceLayer

    - by rockinthesixstring
    I'm trying to follow the tutorial found here to implement a service layer in my MVC application. What I can't figure out is how to wire it all up. here's what I have so far. IUserRepository.vb Namespace Data Public Interface IUserRepository Sub AddUser(ByVal openid As String) Sub UpdateUser(ByVal id As Integer, ByVal about As String, ByVal birthdate As DateTime, ByVal openid As String, ByVal regionid As Integer, ByVal username As String, ByVal website As String) Sub UpdateUserReputation(ByVal id As Integer, ByVal AmountOfReputation As Integer) Sub DeleteUser(ByVal id As Integer) Function GetAllUsers() As IList(Of User) Function GetUserByID(ByVal id As Integer) As User Function GetUserByOpenID(ByVal openid As String) As User End Interface End Namespace UserRepository.vb Namespace Data Public Class UserRepository : Implements IUserRepository Private dc As DataDataContext Public Sub New() dc = New DataDataContext End Sub #Region "IUserRepository Members" Public Sub AddUser(ByVal openid As String) Implements IUserRepository.AddUser Dim user = New User user.LastSeen = DateTime.Now user.MemberSince = DateTime.Now user.OpenID = openid user.Reputation = 0 user.UserName = String.Empty dc.Users.InsertOnSubmit(user) dc.SubmitChanges() End Sub Public Sub UpdateUser(ByVal id As Integer, ByVal about As String, ByVal birthdate As Date, ByVal openid As String, ByVal regionid As Integer, ByVal username As String, ByVal website As String) Implements IUserRepository.UpdateUser Dim user = (From u In dc.Users Where u.ID = id Select u).Single user.About = about user.BirthDate = birthdate user.LastSeen = DateTime.Now user.OpenID = openid user.RegionID = regionid user.UserName = username user.WebSite = website dc.SubmitChanges() End Sub Public Sub UpdateUserReputation(ByVal id As Integer, ByVal AmountOfReputation As Integer) Implements IUserRepository.UpdateUserReputation Dim user = (From u In dc.Users Where u.ID = id Select u).FirstOrDefault ''# Simply take the current reputation from the select statement ''# and add the proper "AmountOfReputation" user.Reputation = user.Reputation + AmountOfReputation dc.SubmitChanges() End Sub Public Sub DeleteUser(ByVal id As Integer) Implements IUserRepository.DeleteUser Dim user = (From u In dc.Users Where u.ID = id Select u).FirstOrDefault dc.Users.DeleteOnSubmit(user) dc.SubmitChanges() End Sub Public Function GetAllUsers() As System.Collections.Generic.IList(Of User) Implements IUserRepository.GetAllUsers Dim users = From u In dc.Users Select u Return users.ToList End Function Public Function GetUserByID(ByVal id As Integer) As User Implements IUserRepository.GetUserByID Dim user = (From u In dc.Users Where u.ID = id Select u).FirstOrDefault Return user End Function Public Function GetUserByOpenID(ByVal openid As String) As User Implements IUserRepository.GetUserByOpenID Dim user = (From u In dc.Users Where u.OpenID = openid Select u).FirstOrDefault Return user End Function #End Region End Class End Namespace IUserService.vb Namespace Data Interface IUserService End Interface End Namespace UserService.vb Namespace Data Public Class UserService : Implements IUserService Private _ValidationDictionary As IValidationDictionary Private _repository As IUserRepository Public Sub New(ByVal validationDictionary As IValidationDictionary, ByVal repository As IUserRepository) _ValidationDictionary = validationDictionary _repository = repository End Sub Protected Function ValidateUser(ByVal UserToValidate As User) As Boolean Dim isValid As Boolean = True If UserToValidate.OpenID.Trim().Length = 0 Then _ValidationDictionary.AddError("OpenID", "OpenID is Required") isValid = False End If If UserToValidate.MemberSince = Nothing Then _ValidationDictionary.AddError("MemberSince", "MemberSince is Required") isValid = False End If If UserToValidate.LastSeen = Nothing Then _ValidationDictionary.AddError("LastSeen", "LastSeen is Required") isValid = False End If If UserToValidate.Reputation = Nothing Then _ValidationDictionary.AddError("Reputation", "Reputation is Required") isValid = False End If Return isValid End Function End Class End Namespace I have also wired up the IValidationDictionary.vb and the ModelStateWrapper.vb as described in the article above. What I'm having a problem with is actually implementing it in my controller. My controller looks something like this. Public Class UsersController : Inherits BaseController Private UserService As Data.IUserService Public Sub New() UserService = New Data.UserService(New Data.ModelStateWrapper(Me.ModelState), New Data.UserRepository) End Sub Public Sub New(ByVal service As Data.IUserService) UserService = service End Sub .... End Class however on the line that says Public Sub New(ByVal service As Data.IUserService) I'm getting an error 'service' cannot expose type 'Data.IUserService' outside the project through class 'UsersController' So my question is TWO PARTS How can I properly implement a Service Layer in my application using the concepts from that article? Should there be any content within my IUserService.vb?

I've created a NSMutableArray and chuck it with 5 data. Testing out how many number it has was fine. But when I tried to use the button function to load the object it return me with object <sampleData: 0x9a2f0e0> - (IBAction)generateNumber:(id)sender { srand(time(NULL)); NSInteger number =rand()% ds.count ; label.text = [NSString stringWithFormat:@"object %@", [ds objectAtIndex:number] ]; NSLog(@"%@",label.text); } While I feel the main cause is the method itself, I've paste the rest of the code below just incase i made any error somewhere. ViewController.h #import <UIKit/UIKit.h> #import "sampleData.h" #import "sampleDataDAO.h" @interface ViewController : UIViewController @property (weak, nonatomic) IBOutlet UILabel *label; @property (weak, nonatomic) IBOutlet UIButton *onHitMePressed; - (IBAction)generateNumber:(id)sender; @property(nonatomic, strong) sampleDataDAO *daoDS; @property(nonatomic, strong) NSMutableArray *ds; @end ViewController.m #import "ViewController.h" @interface ViewController () @end @implementation ViewController @synthesize label; @synthesize onHitMePressed; @synthesize daoDS,ds; - (void)viewDidLoad { [super viewDidLoad]; daoDS = [[sampleDataDAO alloc] init]; self.ds = daoDS.PopulateDataSource; // Do any additional setup after loading the view, typically from a nib. } - (void)viewDidUnload { [self setLabel:nil]; [self setOnHitMePressed:nil]; [super viewDidUnload]; // Release any retained subviews of the main view. } - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { return (interfaceOrientation != UIInterfaceOrientationPortraitUpsideDown); } - (IBAction)generateNumber:(id)sender { srand(time(NULL)); NSInteger number =rand()% ds.count ; label.text = [NSString stringWithFormat:@"object %@", [ds objectAtIndex:number] ]; NSLog(@"%@",label.text); } @end sampleData.h #import <Foundation/Foundation.h> @interface sampleData : NSObject @property (strong,nonatomic) NSString * object; @end sampleData.m #import "sampleData.h" @implementation sampleData @synthesize object; @end sampleDataDAO.h #import <Foundation/Foundation.h> #import "sampleData.h" @interface sampleDataDAO : NSObject @property(strong,nonatomic)NSMutableArray*someDataArray; -(NSMutableArray *)PopulateDataSource; @end sampleDataDAO.m #import "sampleDataDAO.h" @implementation sampleDataDAO @synthesize someDataArray; -(NSMutableArray *)PopulateDataSource { someDataArray = [[NSMutableArray alloc]init]; sampleData * myData = [[sampleData alloc]init]; myData.object= @"object 1"; [someDataArray addObject:myData]; myData=nil; myData = [[sampleData alloc] init]; myData.object= @"object 2"; [someDataArray addObject:myData]; myData=nil; myData = [[sampleData alloc] init]; myData.object= @"object 3"; [someDataArray addObject:myData]; myData=nil; myData = [[sampleData alloc] init]; myData.object= @"object 4"; [someDataArray addObject:myData]; myData=nil; myData = [[sampleData alloc] init]; myData.object= @"object 5"; [someDataArray addObject:myData]; myData=nil; return someDataArray; } @end

  • I'm trying to pass a string from my first ViewController to my second ViewController but it returns NULL

    - by Dashony
    In my first view controller I have 3 input fields each of them take the user input into and saves it into a string such as: address, username and password as NSUserDefaults. This part works fine. In my second view controller I'm trying to take the 3 strings from first controller (address, username and password) create a html link based on the 3 strings. I've tried many ways to access the 3 strings with no luck, the result I get is NULL. Here is my code: //.h file - first view controller with the 3 input fields CamSetup.h #import <UIKit/UIKit.h> @interface CamSetup : UIViewController <UITextFieldDelegate> { NSString * address; NSString * username; NSString * password; IBOutlet UITextField * addressField; IBOutlet UITextField * usernameField; IBOutlet UITextField * passwordField; } -(IBAction) saveAddress: (id) sender; -(IBAction) saveUsername: (id) sender; -(IBAction) savePassword: (id) sender; @property(nonatomic, retain) UITextField *addressField; @property(nonatomic, retain) UITextField *usernameField; @property(nonatomic, retain) UITextField *passwordField; @property(nonatomic, retain) NSString *address; @property(nonatomic, retain) NSString *username; @property(nonatomic, retain) NSString *password; @end //.m file - first view controller CamSetup.m #import "CamSetup.h" @interface CamSetup () @end @implementation CamSetup @synthesize addressField, usernameField, passwordField, address, username, password; -(IBAction) saveAddress: (id) sender { address = [[NSString alloc] initWithFormat:addressField.text]; [addressField setText:address]; NSUserDefaults *stringDefaultAddress = [NSUserDefaults standardUserDefaults]; [stringDefaultAddress setObject:address forKey:@"stringKey1"]; NSLog(@"String [%@]", address); } -(IBAction) saveUsername: (id) sender { username = [[NSString alloc] initWithFormat:usernameField.text]; [usernameField setText:username]; NSUserDefaults *stringDefaultUsername = [NSUserDefaults standardUserDefaults]; [stringDefaultUsername setObject:username forKey:@"stringKey2"]; NSLog(@"String [%@]", username); } -(IBAction) savePassword: (id) sender { password = [[NSString alloc] initWithFormat:passwordField.text]; [passwordField setText:password]; NSUserDefaults *stringDefaultPassword = [NSUserDefaults standardUserDefaults]; [stringDefaultPassword setObject:password forKey:@"stringKey3"]; NSLog(@"String [%@]", password); } - (void)viewDidLoad { [addressField setText:[[NSUserDefaults standardUserDefaults] objectForKey:@"stringKey1"]]; [usernameField setText:[[NSUserDefaults standardUserDefaults] objectForKey:@"stringKey2"]]; [passwordField setText:[[NSUserDefaults standardUserDefaults] objectForKey:@"stringKey3"]]; [super viewDidLoad]; } @end //.h second view controller LiveView.h #import <UIKit/UIKit.h> #import "CamSetup.h" @interface LiveView : UIViewController { NSString *theAddress; NSString *theUsername; NSString *thePassword; CamSetup *camsetup; //here is an instance of the first class } @property (nonatomic, retain) NSString *theAddress; @property (nonatomic, retain) NSString *theUsername; @property (nonatomic, retain) NSString *thePassword; @end //.m second view LiveView.m file #import "LiveView.h" @interface LiveView () @end @implementation LiveView @synthesize theAddress, theUsername, thePassword; - (void)viewDidLoad { [super viewDidLoad]; theUsername = camsetup.username; //this is probably not right? NSLog(@"String [%@]", theUsername); //resut here is NULL NSLog(@"String [%@]", camsetup.username); //and here NULL as well } @end

  • Problem deploying VSTO office addin

    - by zeocrash
    I'm having some issues deploying a visio addin. running the VSTO file works on my computer, but whenever i try and move it to any other user's computer it throws an error on deployment. I thought it might be a setting i'd set in the porject properties so i created an entirely new plugin project and set it to display a message box on startup. The error i'm getting is "the expected element "addin" was not found in the xml"

  • Java: Checking if PC is idle

    - by Scott Straughan
    This is a rather tricky question as I have found no information online. Basically, I wish to know how to check if a computer is idle in Java. I wish a program to only work if the computer is in active use but if it is idle then to not. The only way i can think of doing this is hooking into the mouse/keyboard and having a timer. MSN Messenger has that "away" feature, I wish for something similar to this.

  • Pattern for verifying authenticity of a request to WCF service

    - by fung
    I have a client app that makes calls to a WCF service. This app is on a public computer that's easily accessible and anyone can easily copy the .EXE and .CONFIG of my app into another machine and start using it. Is there a pattern where I can check if the request is coming only from an app on a computer I installed it on and not on one it has been copied to? Thanks in advance.

  • Downloading Python 2.5.4 (from official website) in order to install it

    - by brilliant
    I was quite hesitant about whether I should post this question here on "StackOverflow" or on "SuperUser", but finally decided to post it here as Python is more a programming language rather than a piece of software. I've been recently using Python 2.5.4 that is installed on my computer, but at the moment I am not at home (and won't be for about two weeks from now), so I need to install the same version of Python on another computer. This computer has Windows XP installed – just like the one that I have at home. The reason why I need Python 2.5.4 is because I am using “Google App Engine”, and I was told that it only supports Python 2.5 However, when I went to the official Python page for the download, I discovered that certain things have changed, and I don’t quite remember where exactly from that site I had downloaded Python 2.5.4 on my computer at home. I found this page: http://www.python.org/download/releases/2.5.4/ Here is how it looks: (If you can’t see it here, please check it out at this address: http://brad.cwahi.net/some_pictures/python_page.jpg ) A few things here are not clear to me. It says: “For x86 processors: python-2.5.4.msi For Win64-Itanium users: python-2.5.4.ia64.msi For Win64-AMD64 users: python-2.5.4.amd64.msi” First of all, I don’t know what processor I am using – whether mine is “x86” or not; and also, I don’t know whether I am an “Win64-Itanium” or an “Win64-AMD64” user. Are Itanium and AMD64 also processors? Later it says: “Windows XP and later already have MSI; many older machines will already have MSI installed.” I guess, it is my case, but then I am totally puzzled as to which link I should click as it seems now that I don’t need those three previous links (as MSI is already installed on Windows XP), but there is no fourth link provided for those who use “Windows XP” or older machines. Of course, there are these words after that: “Windows users may also be interested in Mark Hammond's win32all package, available from Sourceforge.” but it seems to me that it is something additional rather than the main file. So, my question is simple: Where in the official Python website I can download Python 2.5.4, precisely, which link I should click?

  • Cannot Install JDK

    - by Vince
    For the life of me, I can't install the JDK on Windows Vista. I keep getting the error, "This Software Has Already Been Installed on Your Computer. Would you like to reinstall it?" Problem is, it's evidently not on my computer, since I can't a) run Eclipse - I get "Could Not Find Java SE Runtime Environment" or b) Find any reference to Java from the command line when typing java -version - I get "Error opening registry key 'Registry/JavaSoft/Java Runtime Environment." Any ideas?

  • IEEE 1003.1 licenses compared

    - by LarsOn
    Software or real people can technically copy a BSD software, install it and sell it. What are technical and licence advantages and disadvantages compared to taking Linux or other 1003.1 and delivering or selling it? Which license is most flexible for instance when selling or delivering a computer BSD licence seems more flexible than Linux and other specs also interesting (Haiku and likewise). Typical case someone wants a computer with which we can deliver BSD or Linux quite similar weighing licence flexibility (BSD seems best licence) and functions (Linux seems have most functions)

  • Preventing cheating in online chess games?

    - by gamedevv
    In many online chess lobbies, I've seen instances of 'engining', where a cheater would open a chess program at the same time as the main game window. He would then set it up so that the opponent's moves are relayed to the computer, then which he would copy the computer's moves, until he (almost always) wins. As a game developer and moderator, what is there to do about this situation?
