  • Why isn't multi-touch working for my imagebuttons?

    - by Droidy
    I'm using imagebuttons that play sounds using SoundPool. Here is example code of one of the imagebuttons: ImageButton Button1 = (ImageButton)findViewById(R.id.sound); Button1.setOnTouchListener(new OnTouchListener() { public boolean onTouch(View v, MotionEvent event) { if (event.getAction() == MotionEvent.ACTION_DOWN ) { mSoundManager.playSound(1); return false; } return false; } }); For some reason, it doesn't allow you to click multiple buttons at the same time. Is it because I'm building for 1.6 SDK? Thanks!

  • Do you know why introducing jquery ui autocomplete for my dropdown boxes is also changing my listbox

    - by oo
    I am trying to change my comboboxes to use autocomplete so i leverage the code listed here (which worked perfectly for my dropdowns) The issue is that i also on the same page have a listbox with the following code: <%= Html.ListBox("Cars", Model.BodyParts.Select( x => new SelectListItem { Text = x.Name, Value = x.Id, Selected = Model.CarsSelected.Any(y => y.Id == x.Id) } ))%> and it appears that the jquery ui code is changing this to a autocomplete dropdown as well (as opposed to keeping it as a multi select list box) any idea how to prevent this from happening? i literally am just using the exact code on this page <script type="text/javascript"> (function($) { $.widget("ui.combobox", { _create: function() { var self = this; var select = this.element.hide(); var input = $("<input>") .insertAfter(select) .autocomplete({ source: function(request, response) { var matcher = new RegExp(request.term, "i"); response(select.children("option").map(function() { var text = $(this).text(); if (!request.term || matcher.test(text)) return { id: $(this).val(), label: text.replace(new RegExp("(?![^&;]+;)(?!<[^<>]*)(" + request.term.replace(/([\^\$\(\)\[\]\{\}\*\.\+\?\|\\])/gi, "\\$1") + ")(?![^<>]*>)(?![^&;]+;)", "gi"), "<strong>$1</strong>"), value: text }; })); }, delay: 0, select: function(e, ui) { if (!ui.item) { // remove invalid value, as it didn't match anything $(this).val(""); return false; } $(this).focus(); select.val(ui.item.id); self._trigger("selected", null, { item: select.find("[value='" + ui.item.id + "']") }); }, minLength: 0 }) .addClass("ui-widget ui-widget-content ui-corner-left"); $("<button>&nbsp;</button>") .insertAfter(input) .button({ icons: { primary: "ui-icon-triangle-1-s" }, text: false }).removeClass("ui-corner-all") .addClass("ui-corner-right ui-button-icon") .position({ my: "left center", at: "right center", of: input, offset: "-1 0" }).css("top", "") .click(function() { // close if already visible if (input.autocomplete("widget").is(":visible")) { input.autocomplete("close"); return; } // pass empty string as value to search for, displaying all results input.autocomplete("search", ""); input.focus(); }); } }); })(jQuery); $(function() { $("select").combobox(); }); </script>

  • Why is win32com so much slower than xlrd?

    - by Josh
    I have the same code, written using win32com and xlrd. xlrd preforms the algorithm in less than a second, while win32com takes minutes. Here is the win32com: def makeDict(ws): """makes dict with key as header name, value as tuple of column begin and column end (inclusive)""" wsHeaders = {} # key is header name, value is column begin and end inclusive for cnum in xrange(9, find_last_col(ws)): if ws.Cells(7, cnum).Value: wsHeaders[str(ws.Cells(7, cnum).Value)] = (cnum, find_last_col(ws)) for cend in xrange(cnum + 1, find_last_col(ws)): #finds end column if ws.Cells(7, cend).Value: wsHeaders[str(ws.Cells(7, cnum).Value)] = (cnum, cend - 1) break return wsHeaders And the xlrd def makeDict(ws): """makes dict with key as header name, value as tuple of column begin and column end (inclusive)""" wsHeaders = {} # key is header name, value is column begin and end inclusive for cnum in xrange(8, ws.ncols): if ws.cell_value(6, cnum): wsHeaders[str(ws.cell_value(6, cnum))] = (cnum, ws.ncols) for cend in xrange(cnum + 1, ws.ncols):#finds end column if ws.cell_value(6, cend): wsHeaders[str(ws.cell_value(6, cnum))] = (cnum, cend - 1) break return wsHeaders

  • Problem with lazy loading implementation

    - by Mehran
    Hi, I have implemented lazy loading in my program. it's done through a proxy class like: class Order { public virtual IList<Item> Items {get; set;} } class OrderProxy { public override IList<Item> Items { get { if (base.Items == null) Items = GetItems(base.OrderID); return base.Items; } set { base.Items = value; } } } the problem is that whenever i instantiate proxy class,without even touching the Items property, it tries to load Items! as you may know,i want to instantiate proxy class and return the instance to BLL instead of domain object itself. what's the problem? Does .NET CLR access(read) properties in a class, when it's instatiating the class? any other methods? Thanks

  • Sharing Jinja2 templates between Pylons and Django applications

    - by Joe Holloway
    I'm writing a couple of Jinja2 templates that basically implement some common grid layouts. I'd like to be able to share this 'library' of templates between a Pylons app and Django app. I've hit a minor stumbling block in that Django's template context is accessible from the "top-level" of the template, whereas Pylons wraps your context inside the thread local c (or tmpl_context) variable. Here are some analogous examples that demonstrate this. Django from django.shortcuts import render_to_response ctx = {} ctx['name'] = 'John' return render_to_response('hello.html', ctx) hello.html: Hello {{ name }} Pylons from pylons import tmpl_context as c from myapp.lib.base import render c.name = 'John' return render('hello.html') hello.html: Hello {{ c.name }} What I'm trying to do is make it so that hello.html is the same across both frameworks. One way I see to do it is by wrapping the Django render_to_response and do something like this: ctx['c'] = ctx But that just doesn't feel right. Anybody see other alternatives to this? Thanks

  • Parsec Haskell Lists

    - by Martin
    I'm using Text.ParserCombinators.Parsec and Text.XHtml to parse an input and get a HTML output. If my input is: * First item, First level ** First item, Second level ** Second item, Second level * Second item, First level My output should be: <ul><li>First item, First level <ul><li>First item, Second level </li><li>Second item, Second level </li></ul></li><li>Second item, First level</li></ul> I wrote this, but obviously does not work recursively list= do{ s <- many1 item;return (olist << s) } item= do{ (count 1 (char '*')) ;s <- manyTill anyChar newline ;return ( li << s) } Any ideas? the recursion can be more than two levels Thanks!

  • Resolving type parameter values passed to ancester type using reflection

    - by Tom Tucker
    I've asked a similar question before, but this one is much more challenging. How do I find a value of a specific type parameter that is passed to an ancestor class or an interface implemented by one of its ancestor classes using reflection? I basically need to write a method that looks like this. // Return the value of the type parameter at the index passed to the parameterizedClass from the clazz. Object getParameterValue(Class<?> clazz, Class<?> parameterizedClass, int index) For the example below, getParameterValue(MyClass.class, Map.class, 1) would return String.class public class Foo<K, V> implements Map<K, V>{ } public class Bar<V> extends Foo<Integer, V> { } public class MyClass extends Bar<String> { } Thanks!

  • content show problem

    - by nonab
    I still fight with some jquery scripts:) With my first problem Jens Fahnenbruck helped me here: http://stackoverflow.com/questions/3021476/problem-with-hide-show-in-jquery thanks:) Now i added another fancy thing - jquery tabs Made a few modifications and it works like this: When you click on tab and it loads different main image for every tab. The problem is that i used $(document).ready(function() to handle those image changes. When i click any of 2x2 box images (on any tab) it will permanently change the image on the right and when i click on tabs it won't work like it did at the beginning. online example: http://rarelips.ayz.pl/testy/2/ code: <style type="text/css"> body { font: Arial, Helvetica, sans-serif normal 10px;

  • Is it considered bad form to execute a function within a conditional statement?

    - by michael
    Consider a situation in which you need to call successive routines and stop as soon as one returns a value that could be evaluated as positive (true, object, 1, str(1)). It's very tempting to do this: if (fruit = getOrange()) elseif (fruit = getApple()) elseif (fruit = getMango()) else fruit = new Banana(); return fruit; I like it, but this isn't a very recurrent style in what can be considered professional production code. One is likely to rather see more elaborate code like: fruit = getOrange(); if(!fruit){ fruit = getApple(); if(!fruit){ fruit = getMango(); if(!fruit){ fruit = new Banana(); } } } return fruit; According to the dogma on basic structures, is the previous form acceptable? Would you recommend it?

Thanks in advance. Best Regards. Jose

  • maths: motion depending on time

    - by clamp
    hello, i have a mathematical problem: i have a function where the only parameter is the current time. the return should be a position which is used to place an object on a certain place. int position(int time) { int x = 0; //TODO implement x depending on time return x; } so basically the function is called every frame to put the object in motion. the motion should look like this (this is the actual question): a linear motion for time A, the object moves at constant speed no motion for time B, the object is stopped repeat at 1. thanks!

  • Minimum needs to Deploy SQL Server Integration Services 2008

    - by Tim
    Hi, I would like to run SSIS 2008 packages on a server that does not have SQL Server 2008 installed on it. I have a simple package to test the concept, but it fails to execute. The return code is 9020 which I have not seen listed as a return code elsewhere. I have copied the following files to the test server that does not have SQL Server 2008 installed on it: SelfContainedSample.dtsConfig Package.dtsx DTExec.exe I am attempting to run the package using a batch file. The line in the batch file that runs the package is: "%dtexecloc%\dtexec.exe" /FILE "%packagefolder%\Package.dtsx" /CONFIGFILE "%configfolder\SelfContainedSample.dtsConfig" /CHECKPOINTING OFF /REPORTING E %logfile% set rc=%errorlevel% I am wondering if there are other requirements that need to be satified to run an SSIS 2008 package on a server that does not have SQL Server 2008 on it? .NET Runtime? SSIS 2008 runtime? Please share your advice if you have a solution or have met this issue before. Thanks, Tim

  • LINQ DefaultIfEmpty(), generating inferred argument error

    - by Refracted Paladin
    I am trying to get the below linq query to return -1 if there isn't any current value. I was looking at this article on MSDN, here, and it seemed that DefaultIfEmpty() was what I wanted. Unfortunately, I am getting a The type arguments cannot be inferred from the usage. Try specifying the type arguments explicitly. error. I guess I am not sure what that means or what it is telling me to do.

  • Constructor invocation returned null: what to do?

    - by strager
    I have code which looks like: private static DirectiveNode CreateInstance(Type nodeType, DirectiveInfo info) { var ctor = nodeType.GetConstructor(new[] { typeof(DirectiveInfo) }); if(ctor == null) { throw new MissingMethodException(nodeType.FullName, "ctor"); } var node = ctor.Invoke(new[] { info }) as DirectiveNode; if(node == null) { // ???; } return node; } I am looking for what to do (e.g. what type of exception to throw) when the Invoke method returns something which isn't a DirectiveNode or when it returns null (indicated by // ??? above). (By the method's contract, nodeType will always describe a subclass of DirectiveNode.) I am not sure when calling a constructor would return null, so I am not sure if I should handle anything at all, but I still want to be on the safe side and throw an exception if something goes wrong.

  • What is the best way get and hold property reference by name in c#

    - by Jeff Weber
    I want to know if there is a better way (than what I'm currently doing) to obtain and hold a reference to a property in another object using only the object and property string names. Particularly, is there a better way to do this with the new dynamic functionality of .Net 4.0? Here is what I have right now. I have a "PropertyReference<T>" object that takes an object name and property name in the constructor. An Initialize() method uses reflection to find the object and property and stores the property Getter as an Action<T> and the property Setter as an Func<T>. When I want to actually call the property I do something like this: int x = _propertyReference.Get(); or _propertyReference.Set(2); Here is my PropertyReference<T> code. Please dissect and make suggestions for improvement. using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Reflection; using System.Xml; namespace WindowsFormsApplication2 { public class PropertyReference<T> : IPropertyReference { public string ComponentName { get; set; } public string PropertyName { get; set; } public bool IsInitialized { get { return (_action != null && _func != null); } } Action<T> _action; Func<T> _func; public PropertyReference() { } public PropertyReference(string componentName, string propertyName) { ComponentName = componentName; PropertyName = propertyName; } public void Initialize(IEntity e) { Object component = e.GetByName(ComponentName); if (component == null) return; Type t = e.GetByName(ComponentName).GetType(); PropertyInfo pi = t.GetProperty(PropertyName); _action = (T a) => pi.SetValue(component, a, null); _func = () => (T)pi.GetValue(component, null); } public void Reset() { _action = null; _func = null; } public void Set(T value) { _action.Invoke(value); } public T Get() { return _func(); } } } Note: I can't use the "Emit" functionality as I need this code to work on the new Windows Phone 7 and that does not support Emit.

  • Using Api to submit userdata to external party

    - by Younes
    I have to submit subscription data to another website. I have got documentation on how to use this API however i'm not 100% sure of how to set this up. I do have all the information needed, like username / passwords etc. This is the API documentation: https://www.apiemail.net/api/documentation/?SID=4 How would my request / post / whatever look like in C# .net (vs 2008) when i'm trying to acces this API? This is what i have now, I think i'm not on the right track: public static string GArequestResponseHelper(string url, string token, string username, string password) { HttpWebRequest myRequest = (HttpWebRequest)WebRequest.Create(url); myRequest.Headers.Add("Username: " + username); myRequest.Headers.Add("Password: " + password); HttpWebResponse myResponse = (HttpWebResponse)myRequest.GetResponse(); Stream responseBody = myResponse.GetResponseStream(); Encoding encode = System.Text.Encoding.GetEncoding("utf-8"); StreamReader readStream = new StreamReader(responseBody, encode); //return string itself (easier to work with) return readStream.ReadToEnd();

  • search through related field for specific related object

    - by dotty
    Hay, I'm working on a simple voting system, where users can vote on a poll. My model looks like this class Poll(models.Model): question = models.CharField() votes = models.IntegerField() usersVoted = models.ManyToManyField(User) Now, i want to scan through the usersVoted field to see if a User object is in there. This User object will then be matched against a logged in User (User obj saved in a session). If the User has voted i want to be able to set a 'has_voted' field. I then want to use this field in my view. I will be using the Property() thingy inside the model to work this 'has_voted' value out. Like so def _can_vote(self): return False can_vote = property(_can_vote) Obviously it'll return a Bool. Any ideas how to search through a related field to find a specific Object?

What might be the error?

  • NSFormatter problem: not getting called for the empty string

    - by Enchilada
    I have created a custom formatter for my (read-only) table column. It looks like this: - (NSString *)stringForObjectValue:(id)anObject { NSAssert([anObject isKindOfClass:[NSString class]] && anObject != nil, @"invalid object"); if ([anObject isEqualToString:@""]) return @"EMPTY"; else return [anObject stringByAppendingString:@"++"]; } Very simple. The corresponding objects are just strings, so it's an string-to-string formatter. All non-empty string objects are returned with @"++" appended to them. Empty string objects should be turned into the @"EMPTY" string. The @"++" gets appended to non-empty strings just fine. The problem is, @"EMPTY" never gets shown! My formatter is never called by Cocoa when the underlying object is the empty string. The corresponding row just keeps being empty, instead of showing my requested @"EMPTY". Any ideas?

  • CouchDB Map/Reduce raises execption in reduce function?

    - by fuzzy lollipop
    my view generates keys in this format ["job_id:1234567890", 1271430291000] where the first key element is a unique key and the second is a timestamp in milliseconds. I run my view with this elapsed_time?startkey=["123"]&endkey=["123",{}]&group=true&group_level=1 and here is my reduce function, the intention is to reduce the output to get the earliest and latest timestamps and return the difference between them and now function(keys,values,rereduce) { var now = new Date().valueOf(); var first = Number.MIN_VALUE; var last = Number.MAX_VALUE; if (rereduce) { first = Math.max(first,values[0].first); last = Math.min(last,values[0].last); } else { first = keys[0][0][1]; last = keys[keys.length-1][0][1]; } return {first:now - first, last:now - last}; } and when processing a query it constantly raises the following execption: function raised exception (new TypeError("keys has no properties", "", 1)) I am making sure not to reference keys inside my rereduce block. Why does this function constantly raise this exception?

    I want to make a pattern route, to redirect users to login page when they are not logged in. I searched but couldn't find a solution. as always Laravel's Documentation is useless! I have this in my filter.php Route::filter('auth', function() { if (Auth::guest()) return Redirect::guest('login'); }); Route::filter('auth.basic', function() { return Auth::basic(); }); And this route in my routes.php Route::when('/*', 'auth' ); but It's not working. How can I do that?

  • Inserting contact with android and querying the result uri returns no entries

    - by th0m4d
    Im developing an application which is dealing with the android contacts API. I implemented methods to insert, update and query contacts. So far everything worked (writing and reading contacts). At one point in my project Im experiencing a strange behaviour. I insert a contact using batch mode. I receive the URI to the RawContact. I do this in a background thread. // use batchmode for contact insertion ArrayList ops = new ArrayList(); int rawContactInsertIndex = ops.size(); // create rawContact ops.add(ContentProviderOperation.newInsert(RawContacts.CONTENT_URI) .withValue(RawContacts.ACCOUNT_TYPE, ConstantsContract.ACCOUNT_TYPE) .withValue(RawContacts.ACCOUNT_NAME, accountName).build()); ops.add(createInsertOperation().withValueBackReference(Data.RAW_CONTACT_ID, rawContactInsertIndex) .withValue(Data.MIMETYPE, StructuredName.CONTENT_ITEM_TYPE) .withValue(StructuredName.DISPLAY_NAME, displayName).withValue(StructuredName.GIVEN_NAME, firstName) .withValue(StructuredName.FAMILY_NAME, lastName).build()); //other data values... ContentProviderResult[] results = context.getContentResolver().applyBatch(ContactsContract.AUTHORITY, ops); if (results.length 0) { result = results[0]; } Then i request and store the lookup uri RawContacts.getContactLookupUri(this.getContentResolver(), myContantRawContactUri); I am able to query the contact using the rawContactUri directly after inserting it (in the same thread). The lookup uri returns null. Uri rawContactUri = appUser.getRawContactUri(ctx); if (rawContactUri == null) { return null; } String lastPathSegment = rawContactUri.getLastPathSegment(); long rawContactId = Long.decode(lastPathSegment); if (rawContactUri != null) { contact = readContactWithID(rawContactId, ContactsContract.Data.RAW_CONTACT_ID); In a different place in the project I want to query the contact i inserted by the stored lookup uri or raw contact uri. Both return no rows from the content provider. I tried it in the main thread and in another background thread. ctx.getContentResolver().query(ContactsContract.Data.CONTENT_URI, null, ContactsContract.Data.RAW_CONTACT_ID + " = ? AND " + ContactsContract.Data.MIMETYPE + " = ?", new String[] { contactID + "", ContactsContract.CommonDataKinds.StructuredName.CONTENT_ITEM_TYPE }, null); My first thought was that it could be related to the context.getContentResolver(). But the android documentation states, that the ContentResolver objects scope is the application's package, so you have on ContentResolver for the whole app. Am I right? What am I doing wrong? Why does the same rawContactUri return the contact at one place and does not on another place? And why do I get a lookup uri from a raw contact, which is not working at all?

  • Override Linq-to-Sql Datetime.ToString() Default Convert Values

    - by snmcdonald
    Is it possible to override the default CONVERT style? I would like the default CONVERT function to always return ISO8601 style 126. Steps To Reproduce: DROP TABLE DATES; CREATE TABLE DATES ( ID INT IDENTITY(1,1) PRIMARY KEY, MYDATE DATETIME DEFAULT(GETUTCDATE()) ); INSERT INTO DATES DEFAULT VALUES; INSERT INTO DATES DEFAULT VALUES; INSERT INTO DATES DEFAULT VALUES; INSERT INTO DATES DEFAULT VALUES; SELECT CONVERT(NVARCHAR,MYDATE) AS CONVERTED, CONVERT(NVARCHAR(4000),MYDATE,126) AS ISO, MYDATE FROM DATES WHERE MYDATE LIKE'Feb%' Output: CONVERTED ISO MYDATE --------------------------- ---------------------------- ----------------------- Feb 8 2011 12:17AM 2011-02-08T00:17:03.040 2011-02-08 00:17:03.040 Feb 8 2011 12:17AM 2011-02-08T00:17:03.040 2011-02-08 00:17:03.040 Feb 8 2011 12:17AM 2011-02-08T00:17:03.040 2011-02-08 00:17:03.040 Feb 8 2011 12:17AM 2011-02-08T00:17:03.040 2011-02-08 00:17:03.040 Linq-to-Sql calls CONVERT(NVARCHAR,@p) when I cast ToString(). However, I am displaying all my data in the ISO8601 format. I would like to override the database default if possible to CONVERT(NVARCHAR,@p,126). I am using Dynamic Linq-to-Sql as demoed by ScottGu to process my data. PropertyInfo piField = typeof(T).GetProperty(rule.field); if (piField != null) { Type typeField = piField.PropertyType; if (typeField.IsGenericType && typeField.GetGenericTypeDefinition().Equals(typeof(Nullable<>))) { filter = filter .Select(x => x) .Where(string.Format("{0} != null", rule.field)) .Where(string.Format("{0}.Value.ToString().Contains(\"{1}\")", rule.field, rule.data)); } else { filter = filter .Select(x => x) .Where(string.Format("{0} != null", rule.field)) .Where(string.Format("{0}.ToString().Contains(\"{1}\")", rule.field, rule.data)); } } I was hoping my property would convert the expression from CONVERT(NVARCHAR,@p) to CONVERT(NVARCHAR,@p,126), however I get a NotSupportedException: ... has no supported translation to SQL. public string IsoDate { get { if (SUBMIT_DATE.HasValue) { return SUBMIT_DATE.Value.ToString("o"); } else { return string.Empty; } } }
