  • A Map of View instances?

    - by user291701
    Is it possible to keep references to views keyed off of their hashCode? Something like: Map<Integer, View> views; views.put(view1.hashCode(), view1); views.put(view2.hashCode(), view2); views.put(viewN.hashCode(), viewN); I have a few in my view hierarchy and am downloading images for each. I want to be able to iterate over them quickly, or see if I've already previously added one (hence the map).

  • Create non-persistent cookie with FormsAuthenticationTicket

    - by Marcus
    Hello! I'm having trouble creating a non-persistent cookie using the FormsAuthenticationTicket. I want to store userdata in the ticket, so i can't use FormsAuthentication.SetAuthCookie() or FormsAuthentication.GetAuthCookie() methods. Because of this I need to create the FormsAuthenticationTicket and store it in a HttpCookie. My code looks like this: DateTime expiration = DateTime.Now.AddDays(7); // Create ticket FormsAuthenticationTicket ticket = new FormsAuthenticationTicket(2, user.Email, DateTime.Now, expiration, isPersistent, userData, FormsAuthentication.FormsCookiePath); // Create cookie HttpCookie cookie = new HttpCookie(FormsAuthentication.FormsCookieName, FormsAuthentication.Encrypt(ticket)); cookie.Path = FormsAuthentication.FormsCookiePath; if (isPersistent) cookie.Expires = expiration; // Add cookie to response HttpContext.Current.Response.Cookies.Add(cookie); When the variable isPersistent is true everything works fine and the cookie is persisted. But when isPersistent is false the cookie seems to be persisted anyway. I sign on in a browser window, closes it and opens the browser again and I am still logged in. How do i set the cookie to be non-persistent? Is a non-persistent cookie the same as a session cookie? Is the cookie information stored in the sessiondata on the server or are the cookie transferred in every request/response to the server? Thanks in advance! /Marcus

  • How to create mobile substrate plugins on XCode?

    - by prathumca
    Hi Everyone, I just wanna create a MS plugin to hook SpringBoard. I'm following "gojohnnyboi" tutorial from here "http://www.ipodtouchfans.com/forums/showthread.php?t=103558". To create a dylib on XCode, I'm following "SkylarEC" tutorial. I mix these two great tutorials and finally got succeed by getting a dylib. But when I placed the dylib in the /Library/MobileSubstrate/DynamicLibraries/ nothing is happened (no alert was shown). By evaluating, I found that, this dylib doesn't have any starting point when it was loaded into the memory. So I mentioned a starting point by declaring a constructor in the .mm file like, __ attribute__((constructor)) static void init() { Class _$SBAppIcon = objc_getClass("SBApplicationIcon"); MSHookMessage($SBAppIcon, @selector(launch), (IMP) &_$ExampleHook_AppIcon_Launch, "_OriginalMethodPrefix"); } But when I'm trying to compile this, I'm getting an error like, Undefined symbols: "_MSHookMessage", referenced from: init() in ExampleHook.o ld: symbol(s) not found collect2: ld returned 1 exit status. Does anyone has idea how to solve this? It would be great and more helpful if anyone share the detailed tutorial/instructions to create a dylib on XCode. P.S I placed all the libsubstrate.dylib and substrate.h files in the corresponding location. And the locations are, libsubstrate.dylib : /Developer/Platforms/iPhoneOS.platform/Developer/usr/lib/ substrate.h : /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.0.sdk/usr/include and my base SDK is 3.0.

  • Wix create non advertised shortcut for all users / per machine

    - by mcdon
    In WIX, how do you create a non advertised shortcut in the allusers profile? So far I've only been able to accomplish this with advertised shortcuts. I prefer advertised shortcuts because you can go to the shortcut's properties and use "find target". In the tutorials I've seen use a registry value for the keypath of a shortcut. The problem is they use HKCU as the root. When HKCU is used, and another user uninstalls the program (since it's installed for all users) the registry key is left behind. When I use HKMU as the root I get an ICE57 error, but the key is removed when another user uninstalls the program. I seem to be pushed towards using HKCU though HKMU seems to behave correctly (per-user vs all-users). When I try to create the non advertised shortcut I get various ICE error such as ICE38, ICE43, or ICE 57. Most articles I've seen recommend "just ignore the ice errors". There must be a way to create the non advertised shortcuts, without creating ICE errors. Please post sample code for a working example.

  • Create win task to run once and delete immediately using C#

    - by pencilslate
    Here is the use case: - Create a new win task, run immediately and once complete, delete the task. Here is basic code to create a task using C#. using (TaskService ts = new TaskService(null)) { string projectName = "runnowtest" + Guid.NewGuid().ToString(); //create new task TaskDefinition td = ts.NewTask(); Trigger mt = null; //setup task as Registration trigger mt = td.Triggers.AddNew(TaskTriggerType.Registration); mt.StartBoundary = DateTime.Now; //delete the task 1 minute after the program ends td.Settings.DeleteExpiredTaskAfter = new TimeSpan(0, 1, 0); //run the notepad++ in the task td.Actions.Add(new ExecAction("notepad.exe")); //register task Task output = ts.RootFolder.RegisterTaskDefinition(projectName, td); //check output Console.WriteLine(output != null ? "Task created" : "Task not created"); } The API doesn't seem to have a property/flag to mark task as run once. I am trying to ensure the above task runs only once and deletes immediately after that. Any thoughts are much appreciated!

  • Create a SSL certificate on Windows

    - by Ben Fransen
    Hi all, Since I'm very new to SSL certificates, and the creation and usage of them I figured maybe StackOverflow members can help me out. I'm from Holland, the common way of online payments is by implementing iDEAL. An online payment protocol supported by the major banks. I have to implement a 'professional' version. This includes creating a RSA private key. Based on that key I have to create a certificate and upload it to the webserver. I'm on a Windows machine and completely confused what to do. I took a look at the OpenSSL website, because the manual forwarded me to that website to get a SSL Toolkit. The manual provides two commands which have to be executed in order to create a RSA key and a certificate. The commands are: openssl genrsa -des3 –out priv.pem -passout pass:myPassword 1024 and openssl req -x509 -new -key priv.pem -passin pass:myPassword -days 3650 -out cert.cer Is there a way I can do this by a utility on a windows machine? I've downloaded PuTTy KeyGenerator. But I'm not sure what to do, I've created a key (SSH-2 RSA, whatever that is..) but how do I create a certificate with that key? Any help is much appreciated! Ben

  • Regex with optional part doesn't create backreference

    - by padraigf
    I want to match an optional tag at the end of a line of text. Example input text: The quick brown fox jumps over the lazy dog {tag} I want to match the part in curly-braces and create a back-reference to it. My regex looks like this: ^.*(\{\w+\})? (somewhat simplified, I'm also matching parts before the tag): It matches the lines ok (with and without the tag) but doesn't create a back-reference to the tag. If I remove the '?' character, so regex is: ^.*(\{\w+\}) It creates a back-reference to the tag but then doesn't match lines without the tag. I understood from http://www.regular-expressions.info/refadv.html that the optional operator wouldn't affect the backreference: Round brackets group the regex between them. They capture the text matched by the regex inside them that can be reused in a backreference, and they allow you to apply regex operators to the entire grouped regex. but must've misunderstood something. How do I make the tag part optional and create a back-reference when it exists?

  • create board for game with events support

    - by netmajor
    How can I create board for simple game, looks like for chess,but user could dynamically change number of column and rows? In cells I could insert symbol of pawn, like small image or just ellipse or rectangle with fill. This board should have possibility add and remove pawn from cells and move pown from one cell to another. My first idea was Grid. I do it in code behind, but it's hurt to implement events or everything in runtime create board :/ int size = 12; Grid board = new Grid(); board.ShowGridLines = true; for (int i = 0; i < size;i++ ) { board.ColumnDefinitions.Add(new ColumnDefinition()); board.RowDefinitions.Add(new RowDefinition()); } //komputer Rectangle ai = new Rectangle(); ai.Height = 20; ai.Width = 20; ai.AllowDrop = true; ai.Fill = Brushes.Orange; Grid.SetRow(ai, 0); Grid.SetColumn(ai,0); //czlowiek Rectangle hum = new Rectangle(); hum.Height = 20; hum.Width = 20; hum.AllowDrop = true; hum.Fill = Brushes.Green; Grid.SetRow(hum,size); Grid.SetColumn(hum,size); board.Children.Add(ai); board.Children.Add(hum); this.Content = board; It's a way to do this dynamically col and row change in XAML ? It's better way to implement that board create and implement events on move pawn from one cell to another ?

  • WPF View/ViewModels using Generics- how?

    - by Investor5555
    New to WPF, so please bear with me... Suppose I have 2 tables in SQL Thing OtherThing Both have the exact same fields: ID (int) Name (string) Description (string) IsActive (bit/bool) DateModified (DateTime) So, I want to create one Model (not two) and do something like this: BaseModel<T>() { public int ID {get;set;} ... } etc. (of course, using the INotifyPropertyChanged, just trying to keep the code simple). I want to be able to create a BaseView and BaseViewModel that would work with whatever model conforms to the Thing/OtherThing. I am really at a loss as to what to do here to make this generic, so I don't have to have a ThingView/ThingViewModel and a OtherThingView/OtherThingViewModel... It seems that this should be simple, but I cannot seem to figure it out. Does anyone have a code example where they could interchange various items from a dropdown list using one view, one ViewModel, and one base datamodel (and switching out the type from a dropdown)? For example, a combobox has 3 identical table structures for Thing OtherThing SomeThing and on selection changed, I want to pull the data from whatever table was selected, to be able to do standard CRUD operations on any of these 3 tables, without having to create concrete classes for each view/viewmodel.

  • Create a dictionary property list programmatically

    - by jovany
    I want to programatically create a dictionary which feeds data to my UITableView but I'm having a hard time with it. I want to create a dictionary that resembles this property list (image) give or take a couple of items. I've looked at "Property List Programming Guide: Creating Property Lists Programmatically" and I came up with a small sample of my own: //keys NSArray *Childs = [NSArray arrayWithObjects:@"testerbet", nil]; NSArray *Children = [NSArray arrayWithObjects:@"Children", nil]; NSArray *Keys = [NSArray arrayWithObjects:@"Rows", nil]; NSArray *Title = [NSArray arrayWithObjects:@"Title", nil]; //strings NSString *Titles = @"mmm training"; //dictionary NSDictionary *item1 = [NSDictionary dictionaryWithObject:Childs, Titles forKey:Children , Title]; NSDictionary *item2 = [NSDictionary dictionaryWithObject:Childs, Titles forKey:Children , Title]; NSDictionary *item3 = [NSDictionary dictionaryWithObject:Childs, Titles forKey:Children , Title]; NSArray *Rows = [NSArray arrayWithObjects: item1, item2, item3, nil]; NSDictionary *Root = [NSDictionary dictionaryWithObject:Rows forKey:Keys]; // NSDictionary *tempDict = [[NSDictionary alloc] //initWithContentsOfFile:DataPath]; NSDictionary *tempDict = [[NSDictionary alloc] initWithDictionary: Root]; I'm trying to use this data of hierachy for my table views. I'm actually using this article as an example. So I was wondering how can I can create my property list (dictionary) programmatically so that I can fill it with my own arrays. I'm still new with iPhone development so bear with me. ;)

  • Table view with custom cell (programmatically)

    - by gotye
    Hey guys, So far, I used to create custom nibs to make my cell as I wanted but this time, the height of a cell will change from one to another so that I can't create a fixed-size cell's nib. So I decided to create it programmatically ... Is the way below the good way to achieve it ? // Customize the appearance of table view cells. - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; UILabel *pseudoAndDate = [[UILabel alloc] initWithFrame:CGRectMake(0.0,0.0,320.0,20.0)]; [pseudoAndDate setTag:1]; [cell addSubview:pseudoAndDate]; [pseudoAndDate release]; } CommentRecord *thisRecord = [comments objectAtIndex:[indexPath row]]; UILabel *label = (UILabel *)[cell viewWithTag:1]; [label setText:[NSString stringWithFormat:@"%@ | %@",thisRecord.author,thisRecord.date]]; return cell; } or .. am i missing something here ? Cause so far it doesn't seem to work ;) Thanks, Gotye.

  • how do i implement / build / create an 'in memory database' for my unit test

    - by Michel
    Hi all, i've started unit testing a while ago and as turned out i did more regression testing than unit testing because i also included my database layer thus going to the database verytime. So, implemented Unity to inject a fake database layer, but i of course want to store some data, and the main opinion was: "create an in-memory database" But what is that / how do i implement that? Main question is: i think i have to fake the database layer, but doesn't that make me create a 'simple database' myself or: how can i keep it simple and not rebuilding Sql Server just for my unit tests :) At the end of this question i'll give an explanation of the situation i got in on the project i just started on, and i was wondering if this was the way to go. Michel Current situation i've seen at this client is that testdata is contained in XML files, and there is a 'fake' database layer that connects all the xml files together. For the real database we're using the entity framework, and this works very simple. And now, in the 'fake' layer, i have top create all kind of classes to load, save, persist etc. the data. It sounds weird that there is so much work in the fake layer, and so little in the real layer. I hope this all makes sense :)

  • jQuery: how to create a new div, assign some attributes, and create an id from some other elements a

    - by Ronedog
    jQuery: how to create a new div, assign some attributes, and create an id from some other elements attributes? How can I accomplish this. What I've tried below is not working and I'm unsure how to make it work. What I'm trying to do is create a div and assign it some attributes, then append this div to all the < li elements that are the on the last node of my unordered list. And lastly, but most important I want to retrieve the value of the attribute called "p_node" from the < li that is being appended to and insert it in as part of the ID of the newly created div. Here's my current jQuery code: $('<div />,{id:"'+ $("#nav li:not(:has(li))").attr("p_node").val() +'_p_cont_div", class:"property_position"}').appendTo("#nav li:not(:has(li))"); Here's the HTML before the div creation: <ul> <li p_node="98" class="page_name">Category A</li> </ul> <ul> <li p_node="99" class="page_name">Category B</li> </ul> Here's what I want it to look like after the new div creation: <ul> <li p_node="98" class="page_name">Category A</li> <div id="98_p_cont_div" class="property_position"></div> </ul> <ul> <li p_node="99" class="page_name">Category B</li> <div id="99_p_cont_div" class="property_position"></div> </ul>

  • Android refresh StateListDrawable problem

    - by Max
    Hi all, I have a strange problem with StateListDrawable or maybe (probably) I'm missing something. I created a test application for it and the same problem occurs. So, this is my StateListDrawable resourse in file test_selection.xml <?xml version="1.0" encoding="utf-8"?> <selector xmlns:android="http://schemas.android.com/apk/res/android"> <item android:state_selected="true"> <shape android:shape="rectangle" android:background="#ff0000"> <corners android:radius="10dp" /> <gradient android:startColor="#ff5555" android:endColor="#ff5555" android:angle="0" /> </shape> </item> <item android:state_selected="false"> <shape android:shape="rectangle" android:background="#eeeeee"> <corners android:radius="10dp" /> <gradient android:startColor="#eeeeee" android:endColor="#eeeeee" android:angle="0" /> </shape> </item> </selector> It's a very simple selector that draw a red color for selected state and a white rect for the unselected one. My main.xml template is very simple. I simply use a TextView that uses the selection as background. <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"> <TextView android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="@string/hello" android:textSize="30dp" android:id="@+id/test_view_example" android:background="@drawable/test_selection"/> <Button android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/refresh" android:onClick="updateView" android:text="refresh"></Button> </LinearLayout> My Activity code is also very simple. public class TestDrawableStateActivity extends Activity { private final static int[] SELECTED_STATE = { android.R.attr.state_selected }; private final static int[] UNSELECTED_STATE = {}; private TextView textView; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); textView = (TextView) findViewById(R.id.test_view_example); } @Override protected void onResume() { super.onResume(); // Carichiamo la Drawable if(textView.getBackground().setState(SELECTED_STATE)){ textView.invalidate(); } } public void updateView(View view) { if(textView.getBackground().setState(SELECTED_STATE)){ textView.invalidate(); }; } } When Activity starts I try to set the state of my Drawable (the StateListDrawable) with the value SELECTED. It seems all very simple.... but the problem is that the state is not shown. If, later, I click a button and execute the method updateView() the state changes. Where is my problem? Where am I wrong? Thankx a lot Max

  • Shortcut to create automatic properties using Visual Studio 2008/2010 or Resharper 5

    - by Piers Myers
    I have a class that contains a load of properties that contain results of some calculations e.g: public class Results { public double Result1 { get; set; } public double Result2 { get; set; } } In a different class I am doing calculations to populate the above properties, e.g: public class Calc { private Results Calc() { Results res = new Results(); res.Result1 = ... some calculation res.Result2 = ... some other calculation res.Result3 = ... // not yet defined in 'Results' class return res; } } When I am writing the Calc class, 'Result3' will be highlighted in red as it is not yet defined in the 'Results' class. Currently I am using the Resharper ALT-Enter shortcut, selecting "Create Property 'Result3'" which will create the following code int the 'Results' class: public double Result3 { get { throw new NotImplementedException(); } set { throw new NotImplementedException(); } } Which I need to manually change to: public double Result3 { get; set; } Then I use the CTRL-Shift-Backspace shortcut to take me back to the 'Calc' class. How can I easily create automatic properties in the 'Results' class if they are not yet defined directly from the 'Calc' class?

  • Design Philosophy Question - When to create new functions

    - by Eclyps19
    This is a general design question not relating to any language. I'm a bit torn between going for minimum code or optimum organization. I'll use my current project as an example. I have a bunch of tabs on a form that perform different functions. Lets say Tab 1 reads in a file with a specific layout, tab 2 exports a file to a specific location, etc. The problem I'm running into now is that I need these tabs to do something slightly different based on the contents of a variable. If it contains a 1 I may need to use Layout A and perform some extra concatenation, if it contains a 2 I may need to use Layout B and do no concatenation but add two integer fields, etc. There could be 10+ codes that I will be looking at. Is it more preferable to create an individual path for each code early on, or attempt to create a single path that branches out only when absolutely required. Creating an individual path for each code would allow my code to be extremely easy to follow at a glance, which in turn will help me out later on down the road when debugging or making changes. The downside to this is that I will increase the amount of code written by calling some of the same functions in multiple places (for example, steps 3, 5, and 9 for every single code may be exactly the same. Creating a single path that would branch out only when required will be a bit messier and more difficult to follow at a glance, but I would create less code by placing conditionals only at steps that are unique. I realize that this may be a case-by-case decision, but in general, if you were handed a previously built program to work on, which would you prefer?

  • why create CLSID_CaptureGraphBuilder2 instance always failed in a machine

    - by Yigang Wu
    It's a real strange issue, the machine information below is from DXDiag. There is no error reported, but create CLSID_CaptureGraphBuilder2 instance always failed in the machine. It's okay to create CLSID_FilterGraph. Before create CLSID_CaptureGraphBuilder2, I have called CoInitialize and created CLSID_FilterGraph. Only this machine has the error, what dll related with this interface or any function needed to call before to make it work? Thanks in advance.

  • Rails: RESTful Find, Initialize, or Create

    - by Andrew
    I have an app that has Cities in it. I'm looking for some suggestions on how to RESTfully structure a controller so that I can lookup, initialize, and create city records via AJAX requests. For instance: Given a text field city_name A user enters the name of a City, like "Paris, France" The app checks this location to see if there is such a city in the database already If there is, it returns the city object If there is not, it returns a new record initialized with the name "Paris" and the country "France", and prompts the user to confirm they want to add this city to the database If the user says "Yes" the record is saved. If not the record is discarded and the form is cleared. Now, my first approach was to change the Create action to use find_or_create, so that an AJAX post to cities_path would result in either returning the existing city or creating it and returning it. That works ok... However, it would be better to setup controller actions that would take a string input, find , or else initialize and return, then only create if the user confirms the generated record is correct. The ideal scenario would put this all in one action so AJAX request can go to that url, the server responds with JSON objects, and javascript can handle things from there. I'd like to keep all the user-interaction logic client side, and also minimize the number of requests it takes to achieve this. Any suggestions on the cleanest, most RESTful way to accomplish this?
