• Pagination For SMS in Android specifically

  - by Priyank

  Hi. I had a pagination related question posted earlier. Here I went through the posted answers and suggested choices and I realized that to implement pagination in an application I could still write db level queries and ensure that I could implement pagination, even if in a crude form. However I have few follow up questions now: I am trying to show SMS from a content provider. Suppose I don't want to use content provider; can I access SMS table in database through my application. Aoes android's security framework allow that? How do people generally handle pagination problems in android, related to content that they are not storing but instead are fetching through content providers. (Android's own or custom) Isn't this a bigger problem. I am surprised to find so little text online about it.

• asp.net mvc - bootstrapping object via model binder

  - by csetzkorn

  Hi, I have a domain object Thing which can contain several Categories. So I have implemented my HTML helper to create a checkbox group of all possible Categories. I have no problem receiving: [AcceptVerbs(HttpVerbs.Post)] public ActionResult Create(Thing Thing, List<string> Categories) However I am wondering whether I could use a custom Model binder to use just this: [AcceptVerbs(HttpVerbs.Post)] public ActionResult Create(Thing Thing) So basically I am looking for a way to use the model binder to bootstrap the object tree/graph. Any pointers appreciated. Thanks. Christian

• How to get a Magento product collection as a comma separated list of SKU's

  - by Sam

  Hi All I have a custom module I made for Magento. From the admin, there is a multi-select list of store products. The selected products from this are output in the form of a comma separated list of SKU's - for example: // Get Featured Products from list $configData = Mage::getStoreConfig('featured_products'); $featuredlist = $configData['settings']['featuredlist']; This gives the output in the following format if I < ?php echo $featuredlist ?: cn,asc,ken,steve,nine,ecco,ana Is it possible to output a collection from a category in the same way, as a comma separated list of SKU's? I currently use the following to get a collection: $_productCollection = Mage::getResourceModel('reports/product_collection') ->addAttributeToSelect('*') ->addAttributeToFilter('visibility', $visibility) ->addCategoryFilter($_category); $_productCollection->load()

• WebOrb - Serializing an object as a string

  - by Robert Wagner

  We have an Adobe Flex client talking to a .NET server using WebORB. Simplifying things, on the .NET side of things we have a struct that wraps a ulong like this: public struct MyStruct { private ulong _val; public override string ToString() { return _val.ToString("x16"); } // Parse method } I want the Flex client to treat this as a string. So that for the following server method: public void DoStuff(int i, MyStruct b); It can call it as DoStuff(1, "1234567890ABCDEF") I've tried playing with custom WebORB serializers, but the documentation is a bit scarce. Is this possible? If so how?

• Huge EAR deployment

  - by bozo

  Hello all, I'm trying to figure out how to deploy a huge (40-50 MB) EAR file to the server through a rather slow VPN connection. The EAR contains EJB and WAR projects created in Glassfish, and 90% of the file size is from external dependency libraries used. Has anyone came up with a strategy for elegant deployment to production system from Netbeans, where the deployment (over the network) is done only for what is really needed (i.e. just one WAR, not the entire EAR, or just one lib, not the entire libraries subproject). Related to the first point, how to separate external dependency libs from project in Netbeans, so that the project compiles on development machine, but when the EAR/WAR/EJB is created it does not contain all the dependency JARs, which are making it huge. Perhaps we need to write custom ant script? Start using maven? Thank you all for kind answers, Bozo

• iPhone - Is it ok to override UITableViewCell setSelected:animated

  - by Brian

  I am drawing custom UITableViewCells. My cells are opaque and are completely drawn in the drawRect of the cell to help with performance. I want to handle the look of a selected cell myself. If I don't, then the contents of my cell is covered up by the selectedBackgroundView that is added. Is it common or acceptable to override the setSelected:animated method of my cell so this is done properly. I guess if I did that, then I would not call the super's setSelected method since I would be handling how the cell will show that its selected. I would also have to set the selected property of the cell. Any help would be great. Thanks.

• Looking for a good example usage of get_or _create in Django views and raising a Form error

  - by Rik Wade

  I am looking for a good example of how to achieve the following: I would like to use get_or_create to check whether an object already exists in my database. If it does not, then it will be created. If it does exist, then I will not create the new object, but need to raise a form error to inform the user that they need to enter different data (for example, a different username). The view contains: p, created = Person.objects.get_or_create( email = registration_form.cleaned_data['email'], defaults = { 'creationDate': datetime.datetime.now(), 'dateOfBirth': datetime.date(1970,1,1) }) So 'p' will contain the existing Person if it exists, or the new Person if not. I would like to act on the boolean value in 'created' in order to skip over saving the Person and re-display the registration_form and raise an appropriate form validation error. The alternative I'm considering is doing a check in a custom Form validation method to see whether a Person exists with the data in the provided 'email' field, and just raising a validation error.

• Zend RegEx Validator error message issue

  - by Mallika Iyer

  Hello, I'm validating a text field in my form as follows: $name = new Zend_Form_Element_Text('name'); $name->setLabel('First Name:') ->setRequired(true) ->addFilter(new Zend_Filter_StringTrim()) ->addValidator('regex',true,array('/^[(a-zA-Z0-9)]+$/')) ->addErrorMessage('Please enter a valid first name'); What I'm trying to accomplish is - how can i display a meaningful error message? Eg: If first name is 'XYZ-', how can i display '- is not allowed in first name.' Is there a way I can access what character the regex is failing for? Would you recommend something else altogether? I thought about writing a custom validator but the regex is pretty simple, so I don't see the point. I couldn't find a decent documentation for the zend 'regex' validator anywhere. If I don't override the default error message, I simple get something like : ';;;hhbhbhb' does not match against pattern '/^[(a-zA-Z0-9)]+$/' - which I obviously don't want to display to the user. I'd appreciate your inputs.

• Changing error message for datatype validation?

  - by Matthias

  Hey guys, I've a small question on ASP.NET MVC 2. I'm using Data Annotations on my Presentation Model and its model binder per default. But one step back, I want to do the most elementary thing: validation of the data type. Let's say I have an "int ID" on my model and want to edit the according entity in my view. If I enter something wrong like "foo", then I get a model error back, but the validation message is on English. I want to have this message in other languages, too. How can I do this? I remember that in MVC 1 I've written a custom model binder which checks the data types, but that's not what I want to do (at least not in MVC 2). Thus I hope there is a better way... Thanks, Matthias

• How do I support the touch of the navigation bar label?

  - by iaefai

  I have an editor that I am making, and I need a way of editing the document's title. I was considering touching the title of the navigation item and have a custom view appear. I did this in an initial version of the application with a button bar item (and target/action), but I cannot seem to find a way to do it with the managed navigation bar. The alternative I was considering was putting another bar at the bottom with an item to do just that, but it doesn't seem like the best design if I don't need to do it, as it takes away from viewing space.

• what possible workarounds are there for "only parameterless constructors are support in Linq to Enti

  - by Ralph Shillington

  In my query I need to return instances of a class that doesn't have a default constructor (specifically this is in a custom Membership provider, and MembershipUser is the culprit) var users = from l in context.Logins select new MembershipUser( Name, l.Username, // username l.Id, // provider key l.MailTo, l.PasswordQuestion, l.Notes.FirstOrDefault().NoteText, l.IsApproved, l.IsLockedOut, l.CreatedOn, l.LastLoginOn.HasValue ? l.LastLoginOn.Value : DateTime.MinValue, l.LastActivityOn.HasValue ? l.LastActivityOn.Value : DateTime.MinValue, DateTime.MinValue, l.LastLockedOutOn.HasValue ? l.LastLockedOutOn.Value : DateTime.MinValue ); is syntacitally correct, but results in a runtime error as Only parameterless constructors and initializers are supported in LINQ to Entities.

• AutoMapper with c# 2.0 syntax

  - by Morri

  I'm trying to create a custom mapping with AutoMapper, but I can't use 3.0 syntax with lambdas. How would one convert this 3.0 code into 2.0 ? Mapper.CreateMap<MyClass, MyDto>() .ForMember(dest => dest.Name, opt => opt.MapFrom(src => src.CompanyName)) Edit: Since there was no better solution, we are now using vs2008 on one workstation to make these mappings and build a dll. I hope it won't be long until we upgrade to vs2010.

• Account preferences crashes on ListPreference

  - by Sionide21

  I have created an account type using the AccountAuthenticator stuff as done in the SampleSyncAdapter tutorial. I am now trying to get account preferences working. I have added the line android:accountPreferences="@xml/account_preferences" to my account-authenticator and account_preferences.xml looks like so: <?xml version="1.0" encoding="utf-8"?> <PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android"> <PreferenceCategory android:title="@string/alum_settings_title"/> <CheckBoxPreference android:key="sync_alum" android:title="@string/sync_alum" android:summaryOn="@string/sync_alum_check" android:summaryOff="@string/sync_alum_nocheck"/> <ListPreference android:key="sync_alum_since" android:title="@string/alum_years" android:entries="@array/years" android:entryValues="@array/years" android:dependency="sync_alum"/> </PreferenceScreen> The checkbox preference works exactly like it should but the ListPreference crashes the entire system with the following message: 05-14 22:32:16.794: ERROR/AndroidRuntime(63): android.view.WindowManager$BadTokenException: Unable to add window -- token null is not for an application I get the same error with EditTextPreference and with the custom subclass of DialogPreference I created.

• mybase.showdialog event fired without apparent reason

  - by António Mendes

  Hi, i'm new to vb .net and oop although i have learned the basics. I'm working in VB and .NET CF 3.5 and i'm trying to pass and received a value with showdialog. The issue here is when i'm done with a procedure in Load, for some reason MyBase.Showdialog (line 3) gives an error of "NullReferenceException was unhandled", but the same procedure doesn't have anything to do with Showdialog. Also, this same error happens with me in other forms when i use AlphaImageButton from AlphaMobileControls. I even created an custom AlphaImageButton with a DialogResult Property and set it to None with no avail. Public Overloads Function ShowDialog(ByRef sArg As String) As String sParam = Split(sArg, vbTab) sArtigo = sParam(0) If MyBase.ShowDialog() = Windows.Forms.DialogResult.OK Then Return lblQuant.Text End If Return Nothing End Function

• When are ASP.NET Expression Builders most useful?

  - by SkippyFire

  I saw an example of using Expression Builders, and creating your own Custom Expression Builder Classes here: http://aspnet.4guysfromrolla.com/articles/022509-1.aspx However, I fail to see the value in using this approach. It doesn't seem much easier than programmatically setting values in your code behind. As far as I can tell, the only thing you can do with them is set properties. Maybe they would be useful for setting defaults on certain controls? Can anyone shed light on where this ASP.NET feature becomes powerful?

• Compile error when trying to _debug_ a Visual Stuio integration project

  - by Rune FS

  I'm currently working on a Visual Studio integration project for VS2010 (a custom highlighter) I'm using Irony and the LanguageServiceTemplate from this Code project article. However that template is build for 2008 and the changes made in VS2010 when it comes to integrating breaks the template. When I try to compile I get the following error: Source.extension.vsixmanifest file not found in project. If a file with this name is present in the project, make sure the build action is set to "None". Any ides of what I can do to fix it?

• Database independent row level security solution

  - by Filip

  Hi, does anybody knows about Java/C# database independent authorization library. This library should support read, write, delete, insert actions across company organizational structure. Something like this: - user can see all documents - user can enter new document assigned to his unit - user can change all documents assigned to his unit and all subordinate units. - user can delete documents that are assigned to him I should also be able to create custom actions (besides read, write,...) connect them to certain class and assign that "security token" to user (e.g. document.expire). If there aren't any either free or commercial libraries, is there a book that could be useful in implementing this functionality? Thanks.

• Emacs: annoying Flymake dialog box.

  - by baol

  Hello I have the following lines in my ~/.emacs.d/init.el (custom-set-variables '(flymake-allowed-file-name-masks (quote ( ("\\.cc\\'" flymake-simple-make-init) ("\\.cpp\\'" flymake-simple-make-init))))) (add-hook 'find-file-hook 'flymake-find-file-hook) When I open a cc/cpp file that has a Makefile with the following content in the same folder I get proper on-the-fly compilation and error reporting (Flymake will check the syntax and report errors and warnings during code editing) .PHONY: check-syntax check-syntax: $(CXX) -Wall -Wextra -pedantic -fsyntax-only $(CHK_SOURCES) The problem is that when I open a .cc file that has no corresponding Makefile i get an annoying dialog box that warns me about flymake being disabled for every file opened. Is there some hook I can use to disable that warning? Can you provide sample elisp code and explanation on how you found the proper hook?

• ASP.NET - dynamically creating database connection in datasets

  - by Foo

  I am currently using datasets for my data access layer. I currently store the connection string in the web.config file. I need the ability to change the connection to another database before any queries are processed. Is there an event that is triggered or a base class that can be modified that intercepts the process of retrieving the connection string from the web.config file? Is there any way to handle multiple database connections using the same code base and also take advantage of the connection pooling? I understand the best method is to get rid of datasets and use custom data objects. Any ideas?

• How to customize pickle for django model objects

  - by muudscope

  I need to pickle a complex object that refers to django model objects. The standard pickling process stores a denormalized object in the pickle. So if the object changes on the database between pickling and unpickling, the model is now out of date. (I know this is true with in-memory objects too, but the pickling is a convenient time to address it.) So what I'd like is a way to not pickle the full django model object. Instead just store its class and id, and re-fetch the contents from the database on load. Can I specify a custom pickle method for this class? I'm happy to write a wrapper class around the django model to handle the lazy fetching from db, if there's a way to do the pickling.

• How to determine the maximum integer the model can handle?

  - by John Mee

  "What is the biggest integer the model field that this application instance can handle?" We have sys.maxint, but I'm looking for the database+model instance. We have the IntegerField, the SmallIntegerField, the PositiveSmallIntegerField, and a couple of others beside. They could all vary between each other and each database type. I found the "IntegerRangeField" custom field example here on stackoverflow. Might have to use that, and guess the lowest common denominator? Or rethink the design I suppose. Is there an easy way to work out the biggest integer an IntegerField, or its variants, can cope with?

• What should I use for the .SWF path in FlowPlayer's configuration if I'm developing from my desktop?

  - by codeninja

  I'm having an extremely difficulty time getting the flowplayer to show up and the worst part is I have no idea what is wrong because I'm not getting any error messages! I have an external javascript file: C:/desktop/mysite/js/jq/plugins.js calling $f() from: C:/desktop/mysite/thirdparty/flowplayer/flowplayer.js the swf files also live there... I'm working on file/desktop (no localhost or webserver) $(video.id).flowplayer("thirdparty/flowplayer/flowplayer-3.1.15.swf", { clip:{ .... }, // min Flash version version:[9,115], // older versions will see a custom message onFail:function(){ alert("Failed!"); }, onError:function(errCode,errMsg){ alert(errCode+errMsg); } }); I don't know what path to use for the SWFs to get them to load, is the path relative to the javascript (plugins.js) that calls $f() or is it relative to the path of the flowplayer.js ?? bangs head on wall

• CPP extension and multiline literals in Haskell

  - by jetxee

  Is it possible to use CPP extension on Haskell code which contains multiline string literals? Are there other conditional compilation techniques for Haskell? For example, let's take this code: -- If the next line is uncommented, the program does not compile. -- {-# LANGUAGE CPP #-} msg = "Hello\ \ Wor\ \ld!" main = putStrLn msg If I uncomment {-# LANGUAGE CPP #-}, then GHC refutes this code with a lexical error: [1 of 1] Compiling Main ( cpp-multiline.hs, cpp-multiline.o ) cpp-multiline.hs:4:17: lexical error in string/character literal at character 'o' Using GHC 6.12.1, cpphs is available. I confirm that using cpphs.compat wrapper and -pgmP cpphs.compat option helps, but I'd like to have a solution which does not depend on custom shell scripts. -pgmP cpphs does not work. P.S. I need to use different code for GHC < 6.12 and GHC = 6.12, is it possible without preprocessor?
