• Android animation clipping when going between layouts

  - by Ravedave

  I have a fairly complex layout. I use a relative layout as the root and then inside of it I have a few table views and some further nesting. When I animate an imageview between these layouts my image clips. I have a background on the parent layout and the animation looks like it's going under it. I have set android:clipChildren="false" and android:clipToPadding="false" on all of the layouts. I've also set anim.setZAdjustment(Animation.ZORDER_TOP); on all of my animations. What am I doing wrong?

• Can't store array in json field in postgresql (rails) can't cast Array to json

  - by Drew H

  This is the error I'm getting when I run db:migrate rake aborted! can't cast Array to json This is my table class CreateTrips < ActiveRecord::Migration def change create_table :trips do |t| t.json :flights t.timestamps end end end This is in my seeds.rb file flights = [{ depart_time_hour: 600, arrive_time_hour: 700, passengers: [ { user_id: 1, request: true } ] }] trip = Trip.create( { name: 'Flight', flights: flights.to_json } ) For some reason I can't do this. If I do this. trip = Trip.create( { name: 'Flight', flights: { flights: flights.to_json } } ) It works. I don't want this though because now I have to access the json array with trip.flights.flights. Not the behavior I'm wanting.

• How to push UIViewController into UINavigationController from seperate UIView of different UIViewCon

  - by Kundan

  I have a UIViewController(AbcViewController) with NavigationController.AbcViewController uses UIView(AbcView) as its view. AbcView has a UITableView. I have set This TableView's datasource in AbcViewController and delegate in its SuperView i.e. AbcView. How will I push another UIViewController(XyzViewcontroller) into navigationController when I select a row in this table because it gives "error: request for member 'navigationController' in something not a structure or union" when I do this : [self.navigationController pushViewController:xyzViewcontroller animated:TRUE]; I also did this : AbcViewController *parentVC; [parentVC.navigationController pushViewController:xyzViewcontroller animated:TRUE]; Though it builds successfully but XyzViewcontroller's view does not appear. It does not push XyzViewcontroller's view into navigationController. Thanks For Any Help.

• How to query the like count of a facebook object such as a album or photo via fql?

  - by hip10

  Hi, Here is a tricky question, how do you get the like count of a facebook object such as an album or a photo? I know that facebook has a fql table called link_stat that allow you to get the like count for an external url, but it does not seem to work if the object is within facebook. If you access the likes via the opengraph api on a particular object, it will only return a maximum of 4 users that like the object, even though there maybe a few thousand users that like it. Any clues?

• How to get MAX value of a version-number (varchar) column in T-SQL

  - by Ogre Psalm33

  I have a table defined like this: Column: Version Message Type: varchar(20) varchar(100) ---------------------------------- Row 1: 2.2.6 Message 1 Row 2: 2.2.7 Message 2 Row 3: 2.2.12 Message 3 Row 4: 2.3.9 Message 4 Row 5: 2.3.15 Message 5 I want to write a T-Sql query that will get message for the MAX version number, where the "Version" column represents a software version number. I.e., 2.2.12 is greater than 2.2.7, and 2.3.15 is greater than 2.3.9, etc. Unfortunately, I can't think of an easy way to do that without using CHARINDEX or some complicated other split-like logic. Running this query: SELECT MAX(Version) FROM my_table will yield the erroneous result: 2.3.9 When it should really be 2.3.15. Any bright ideas that don't get too complex?

• Why can't I see the 'dataset project' property in Visual Studio DataSet designer?

  - by Ryan

  Hi, I am trying to follow 'n tier app design' tutorials and they tell me to set the DataSet Project property from the Data Set Designer in VS, to split table adaptors and entities into seprate projects. I can't see that property! (I'm looking in the same place shown on the videos... all other properties match) Does anybody know why? The video is here http://windowsclient.net/learn/video.aspx?v=14625 (4:36 is where the property is set) I'm using VS c# 2008 Express, with SQL Server Express 2008. Thanks a lot for any help Ryan

• Change Ssms2008 default setting on installation

  - by CziX

  Hey, I am currently developing a vbs script, which installs SQL server 2008 + SP1. After the install I want to change the default settings in the Ssms, such as "Prevent saving changes that require table recreation" and such on. I can't figure out, where Ssms hides its settings. Currently I am looking at 1) My Documents\SQL Server Management Studio\ 2) HKCU\Software\Microsoft\Microsoft SQL Server\100\Tools\Shell\Profile But whenever I change a "setting" in the vssettings-file in 1), Ssms thinks it is first time it runs, and overwrite. How can I change the Ssms setting manual, without doing it from the Ssms itself?

• Best practices for combining Lucene.NET and a relational database?

  - by FlySwat

  I'm working on a project where I will have a LOT of data, and it will be searchable by several forms that are very efficiently expressed as SQL Queries, but it also needs to be searched via natural language processing. My plan is to build an index using Lucene for this form of search. My question is that if I do this, and perform a search, Lucene will then return the ID's of matching documents in the index, I then have to lookup these entities from the relational database. This could be done in two ways (That I can think of so far): N amount of queries (Horrible) Pass all the ID's to a stored procedure at once (Perhaps as a comma delimited parameter). This has the downside of being limited to the max parameter size, and the slow performance of a UDF to split the string into a temporary table. I'm almost tempted to mirror everything into lucenes index, so that I can periodicly generate the index from the backing store, but only need to access it for the frontend. Advice?

• Bash alias to open Vim at last cursor position mark

  - by Pierre LaFayette

  The mark " in Vim takes you to your last cursor position. I want to create an alias that will open my Vim instance and jump to that mark; something which is obviously extremely useful. This works from the command line: $ vim -c "'\"" File.cpp Now I want to make an alias for this: $ alias v='vim -c "'\""' Well that's not going to work! You need to escape the first single quote you say... $ alias v='vim -c "\'\""' Hmm. That didn't work either... So I try a whole lot of variations of single quoted and double quoted madness, bang my head against the table and load up stackoverflow in my browser, and here we are. How do I properly escape this alias?

• Hash of unique value = unique hash?

  - by Nebs

  Theoretically does hashing a unique value yield a unique value? Let's say I have a DB table with 2 columns: id and code. id is an auto-incrementing int and code is a varchar. If I do ... $code = sha1($id); ... and then store $code into the same row as $id. Will my code column be unique as well? What about if I append the current time? eg: $code = sha1($id . time()); Thanks.

• L2E delete exception

  I have following code to delete an user from database: try { var user = from u in db.Users where u.Username == username select u; if (user.Count() > 0) { db.DeleteObject(user.First()); db.SaveChanges(); } } but I got exception like this: at System.Data.Mapping.Update.Internal.UpdateTranslator.Update(IEntityStateManager stateManager, IEntityAdapter adapter) at System.Data.EntityClient.EntityAdapter.Update(IEntityStateManager entityCache) at System.Data.Objects.ObjectContext.SaveChanges(Boolean acceptChangesDuringSave) at System.Data.Objects.ObjectContext.SaveChanges() at MyCompany.SystemSoftware.DQMgr.User.DeleteUser(String username) in C:\workspace\SystemSoftware\SystemSoftware\src\dqm\User.cs:line 479 The Users table is referenced by few other tables. It is probably caused by the foreign key constraint?

• Best way to produce automated exports in tab-delimited form from Teradata?

  - by Cade Roux

  I would like to be able to produce a file by running a command or batch which basically exports a table or view (SELECT * FROM tbl), in text form (default conversions to text for dates, numbers, etc are fine), tab-delimited, with NULLs being converted to empty field (i.e. a NULL colum would have no space between tab characters, with appropriate line termination (CRLF or Windows), preferably also with column headings. This is the same export I can get in SQL Assistant 12.0, but choosing the export option, using tab delimiter, setting my NULL value to '' and including column headings. I have been unable to find the right combination of options - the closest I have gotten is by building a single column with CAST and '09'XC, but the rows still have a leading 2-byte length indicator in most settings I have tried. I would prefer not to have to build large strings for the various different tables.

• Foreign key onto weak entity set in MS SQL Server 2008?

  - by Nic Waller

  I'm using Microsoft SQL Server 2008 Management Studio to create a relational schema by following an Entity-Relationship diagram. (included below; unrelated details removed) Until now, primary and foreign keys have been working as expected. But when I try to create a foreign key from the entity relationship takes onto the weak entity set section, I get an error. Section is identified by a composite primary key in the context of course, which has course_id as a primary key. Therefore, the primary key of section is a 4-way composite key. The entity relationship takes needs to refer to section, so it includes all 4 primary attributes from section in it's own primary key. When trying to establish a foreign key relationship from takes to section, Studio gives the following error: The columns in table 'section' do not match an existing primary key or UNIQUE constraint. Am I doing something wrong, or is this an unsupported configuration? I can provide more details or the SQL schema if necessary.

• GWT - How to define a Widget outside layout hierarchy in uibinder xml file

  - by mr_room

  Hello, this is my first post. I hope someone could help me. I'm looking for a way to define a widget in UiBinder XML layout file separately, without being part of the layout hierachy. Here's a small example: <ui:UiBinder xmlns:ui="urn:ui:com.google.gwt.uibinder" xmlns:g="urn:import:com.google.gwt.user.client.ui"> <g:Label ui:field="testlabel" text="Hallo" /> <g:HTMLPanel> ... </g:HTMLPanel> The compile fails since the ui:UiBinder element expects only one child element. In Java Code i will access and bind the Label widget as usual: @UiField Label testlabel; For example, this could be useful when you define a Grid or FlexTable - i want to define the Labels for the table header within the XML layout file, not programmatically within the code. Many thanks in advance

• Telling a UITextField to become first responder while embedded in a UITableViewCell

  - by Jasarien

  I have a UITextField that is a subview of a UITableViewCell. When my view loads, I want the text field to become first responder. I have a pointer to the text field in the table cell, so to do this I am trying: [myTextField becomeFirstResponder]; This returns NO all the time, regardless of when it's called, which according to the docs means the text field refused to become first responder... What am I doing wrong? Edit: The text field properly responds to being touched. It bring up the keyboard then. It's only when telling it to become first responder programmatically that the problem happens.

• Membership provider stopped working on using Membership Provider in ASP.Net MVC

  - by Michael Meadows

  I have a production ASP.Net MVC application that has been using the membership service. It has worked fine, up until today. Nothing has changed on the server, but I now have this error: System.Configuration.Provider.ProviderException: The 'System.Web.Security.SqlMembershipProvider' requires a database schema compatible with schema version '1'. However, the current database schema is not compatible with this version. You may need to either install a compatible schema with aspnet_regsql.exe (available in the framework installation directory), or upgrade the provider to a newer version. I checked the asp_schemaversions table, and it looks fine. Please any help would be appreciated.

• How to replace all instances of a particular value in a mysql database with another?

  - by Joseph

  I'm looking for a MySQL equivalent of what str_replace is for PHP. I want to replace all instances of one word with another, I want to run a query that will replace all "apples" with "oranges". The reason why: UPDATE fruits SET name='oranges' WHERE name='apples'; isn't going to work for my situation, is because I often times have multiple words in a table row separated by commas like: "apples, pears, pineapples". In this case I want just apples to be replaced by oranges and pear and pineapples to stay in tact. Is there any way to do this?

• HTMLAgilityPack ChildNodes index works, named node does not

  - by XgenX

  I am parsing an XML API response with HTMLAgilityPack. I am able to select the result items from the API call. Then I loop through the items and want to write the ChildNodes to a table. When I select ChildNodes by saying something like: sItemId = dnItem.ChildNodes(0).innertext I get the proper itemId result. But when I try: sItemId = dnItem.ChildNodes("itemId").innertext I get "Referenced object has a value of 'Nothing'." I have tried "itemID[1]", "/itemId[1]" and a veriety of strings. I have tried SelectSingleNode and ChildNodes.Item("itemId").innertext. The only one that has worked is using the index. The problem with using the index is that sometimes child elements are omitted in the results and that throw off the index. Anybody know what I am doing wrong?

• Fine tune some SQL called multiple times

  - by Carl

  Hi all, I currently have an SQL query which is currently called multiple times like this (pseudo code): foreach(KeyValuePair kvp in someMapList) { select col1 from table where col2 = kvp.key and col3 = kvp.value; //do some processing on the returned value } The above could obviously call the database a large number of times if it is a big list of pairs. Can anyone think of a more efficient piece of SQL which could essentially return a list of specific values based on a list of two unique pieces of information so that the processing can be done in bulk? One obvious one would be to build up a big piece of SQL with ORs but this would probably be quite inefficient? Thanks Carl
