• Sql server execute permission; failure to apply permissions

  - by WestDiscGolf

  I've just migrated from SQL2000 to SQL2008 and I have started getting an execute permission issue on a stored proc which uses sp_OACreate. The rest of the system works fine with the db login which has been setup and added to the database. I've tried: USE master GO GRANT EXEC ON sp_OACreate TO [dbuser] GO But this fails with the following error: Msg 15151, Level 16, State 1, Line 1 Cannot find the user 'dbuser', because it does not exist or you do not have permission. I'm logged into the server as sa with full permissions. I can execute a similar sql statement and apply the permissions to a server role, however not a login/user. How do I apply the changes to the specific user/login? I can apply the permissions to the public role and it resolves my issue; however this seems to be a security issue to me which I don't really want to apply to the live server.

• ASP.NET MVC Render Ajax / Standard View

  - by Wayne

  I am a little confused and making it alot more complicated than this needs to be! Here is what I have... A view which displays a drop down of US States. When the user chooses a state it loads a list of data from a database and returns the results (populates the View Model) and the View renders the information. What I wanted to do was have have the dropdown trigger an Ajax event which performs the data load, but also wanted it to depreciate if the user didn't have Javascript enabled. How would I go about rendering the view with AND without javascript / ajax? Hope that makes sense. Thanks for your help.

• Can I assume Flash and PHP will generate the same floating point numbers?

  - by Fragsworth

  In a multiplayer game I'm developing, we have a few values that are floating point numbers. The back-end (in PHP) and the front-end (in Flash) occasionally perform the same calculations on these numbers, to minimize communication. I am currently making sure that both sides are using 64-bit doubles, but am I safe to assume that all calculations will be the same? For instance, what about string to float conversion - should I worry about Flash having a potentially different implementation as PHP? (If this happens, our game will go out of sync - the client will think it is in one state while the server is in another) With some testing, it appears to be the same, but I'm just not sure. Can someone clarify this for me?

• How can I seperate my TransactionScope so they don't interfere with each other?

  - by shenku

  I have some business logic that executes within a simple TransactionScope. using (var scope = new TransactionScope()) { // does some logic. // then some more... scope.Complete(); } During execution an ado exception ocurres and the transaction is on it's way to being disposed. In the mean time the exception is captured further upstream, and I try to log it to my database, via another connection. At this point I get another error saying The operation is not valid for the state of the transaction. Eeek! Now I can see I am able to use IsolationLevel, to change the way my transactions interact, but is this the right thing to do? And which should I use?

• What is the precision of the priority field in sitemap.xml?

  - by Christoph

  Unfortunately the specification does not tell anything about precision. The xml scheme definition states that it is of the type xsd:decimal: <xsd:restriction base="xsd:decimal"> <xsd:minInclusive value="0.0"/> <xsd:maxInclusive value="1.0"/> </xsd:restriction> I have a sitemap generator that uses up to 10 positions after decimal point. Where often only the last few positions differ. These numbers are perfectly right according to the xsd, but yet i found some pages(3,4) that state that only 0.0, 0.1, 0.2, .., 1.0 are valid values. How will the search engines react to such a sitemap? Will some just round the value? I know that it is unlikely that someone can provide an answer to that question, unless he works for that search engine, but i think experiences will also do.

• How to indicate to user that a command affects a subset of a multiple selection?

  - by Zamboni

  Here is an example that illustrates my question. I have a program that lists 1000 items. I select 10 of 1000 items. The program enables a button indicating that a command is available for my selection. I click the button, and a window appears. I make some change in the window and click OK. The command changes 5 of the 10 items in my multiple selection, and those 5 changed items now reflect a modified state in my list. My question is: How do I indicate to user that the command affects a subset of a multiple selection before clicking OK? Can anyone cite examples of existing products that handle this scenario well?

• Can I access an iframe of the same domain in a separate window?

  - by jozecuervo

  How can I detect the presence of and then call a function on a frame that is already loaded in one tab (my iframed facebook app) from a page being loaded in a new tab (from an ad-served link). It seems most examples focus on parent/child iframe communication. In this case, a link will be served from Google Ad Manager, which only allows _top or _blank to be targeted. I want to pass an id through the ad click into the new page/tab on my domain and then JS call over to the frame my app is in to switch state. Both frames are on my domain but not in the same document or window. Is this possible?

• Can somehow show progress on file upload without using AJAX?

  - by nimo

  Let's say that I upload a file using a basic multipart post. The server then receives the request and starts to execute the server side code. Can I somehow in that state start to output the response and after some data is sent start to receive the file? Finally when the file is uploaded I output the rest of the response. If this is possible I can display file upload progress without using ajax? I guess this might depend on what I run server side. But let's assume that I have full network control.

• Rails 3 Nested Forms

  - by Mike

  I have a Person model and an Address Model: class Person < ActiveRecord::Base has_one :address accepts_nested_attributes_for :address end class Address < ActiveRecord::Base belongs_to :person end In my people controller I have @person.build_address in my new action. My forms builds correctly. The problem is that when I submit the form, a person record and an address record is created but they aren't linked via the address_id column in the Person table.

• Asp.net Page and control Events

  - by andrewWinn

  I have looked all over the web and I can not find the information I am looking for and I was hoping that someone could give me a hand. Specifically, I am looking for a comprehensive list of what events occur in the page and control life cycles and what is "available" in each event. Like when can I get a dropdownlists selected value, when can i databind, when can I get at values in view state and what not. Can anyone point me to a comprehensive list for both page and control life cycles? Or even provide that information for me? Thanks in advance.

• MSMQ empty object on message body

  - by Owen

  Ok, so I'm very VERY new to MSMQ and I'm already confused. I have created a private queue and added a few messages to it, all good so far. BUT when I retrieve the messages back from the queue the message body contains a empty object of the type I added. By this I don't mean that the body is null, it does have a reference to a type of the object that I added, but it's not instantiated so all the properties are in their null or default state. This is the code I use to add to the queue: using (var mQueue = new MessageQueue(QueueName)) { var msg = new Message(observation) { Priority = MessagePriority.Normal, UseJournalQueue = true, AcknowledgeType = AcknowledgeTypes.FullReceive, }; mQueue.Send(msg); } And this is the code that dequeues the messages: using (var mQueue = new MessageQueue(QueueName)) { mQueue.MessageReadPropertyFilter.SetAll(); ((XmlMessageFormatter)mQueue.Formatter).TargetTypes = new[] { typeof(Observation) }; var msg = mQueue.Receive(new TimeSpan(0, 0, 5)); var observation = (Observation)msg.Body; return observation; }

• Ruby on Rails: how to sort data in an array of active record objects right before iterating?

  What is the best way to sort an array of active record objects by by a field? This array is a field of an object, link_pages, and I want it sorted by the field "sequence" <% @menu_bar.link_pages.each do |lp| %> <li id="page_<%= lp.id%>" class="ui-state-default"> <span class="ui-icon ui-icon-arrowthick-2-n-s"></span> <font size=5><%= lp.name %></font> | <%= link_to "remove", :controller => "admin/menu_bars", :action => :remove_page_from_menu, :page => lp.id, :id => @menu_bar.id %> </li> <% end %> maybe there is a way to do @menu_bar.link_pages.sort_by_sequence.each do .... that would be slick... but I just don't know.

• Rails group validation with just one error message

  - by Victor

  The following validation code in the model: validates :formatted_address, :zip, :city, :state, :country, :presence => true, :message => "is incomplete. Please enter full address." is displayed when either of the fields are empty. Let's say now :address and country are empty, 2 errors are displayed: Formatted Address is incomplete. Please enter full address. Country is incomplete. Please enter full address. How can I group the error message in the validation to just show one error message if either of the fields validated does not exist? Address is incomplete. Please enter full address. Thanks.

• Hibernate Unit tests - Reset schema

  - by Marco

  Hi, I'm testing the CRUD operations of my DAOs in JUnit tests. When i execute the single test, Hibernate always resets the schema and populates the DB in a known state. But when i execute multiple tests in a row, Hibernate resets the schema once, and then the data is accumulated during the execution of the tests. This is an unexpected behavior, so I'd like to add in the @Before method of the tests a function that explicitly resets the schema to avoid the pesistence of side data created by previous tests during the execution chain. Any tips? Thanks

• Why can't I pass in a uniqueidentifier/GUID to a stored procedure

  - by chobo2

  Hi I have this SP USE [TestDB] GO /****** Object: StoredProcedure [dbo].[sp_test] Script Date: 06/12/2010 11:47:27 ******/ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO CREATE PROCEDURE [dbo].[sp_test] @id uniqueidentifier AS BEGIN select * from TestTbl where ProductId= @id END I then went to the SP with ms sql 2005 and clicked execute. It comes up with a box where I entered in the GUID. I copied and pasted it straight from my test database. I get this error. Msg 102, Level 15, State 1, Line 5 Incorrect syntax near 'cac671b'. So why can't I sent in GUIDs? even ones that are copied right from the database and must be valid as they where allowed into the db.

• Android asking for unneeded permissions

  - by steveo225

  I have an Android widget that needs internet access, fine and coarse permissions only. However, when I install the apk file, it says it also needs access to read the phone state and identity, and access to storage. It doesn't need access to either, and the only permissions that are in the mainfest are: <uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /> <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" /> Any ideas on why this is happening? Thanks for the help.

• How can I get an error or a warning from a PreparedStatement?

  - by Geo

  I had an update like this: update table set col1=?,col2=?,col3=? where col4=?; and I filled it up like this: statement.setString(1,"some_value"); statement.setString(2,"some_value"); statement.setString(3,"some_value"); and I forgot to add a fourth value.I did a executeUpdate and of course nothing happened to the database. I spent about 1 hour debugging it, to see where it goes wrong. I then modified my code to print the SQLWarning object returned by the getWarnings method. It always returned null. I even modified the code to the buggy state it was, before I set the fourth parameter, and still no warning. Does anyone know how one can get an error/warning? If it matters, my Connection is set to autoCommit.

• jquery ajax call errors in chrome onenter with no responseText

  - by wham12

  I've built a login page that uses a .ajax call to a generic c# handler (.ashx) to validate the username and password before allowing the user to log in. If you click on the login link <a href="#" class="ui-state-default ui-corner-all CustomButton" onclick="goLogin();return false"> the .ajax call returns successfully and it logs the user in. I am trying to make it so the user can also just press the "enter" key from the password box: $("#pword").keydown(function(e) { if (e.keyCode == 13) { goLogin(); } }); Using Firefox, both ways work just fine and the user is logged in. With Chrome however, pressing "enter" hits the error function of my .ajax call and will not log the user in. The parameters and responses look identical through Firefox's console, as expected. What would be causing this and/or how can I debug it in Chrome?

• Hide or Disable? In this example and in general...

  - by George

  I have the following set of controls. Scenario 1: If you select one of the first 3 radio buttons and click enter, focus will jump to the Passport Number text box. If the user selects "Other", the "Other, Please Specify" textbox is enabled and, for convenience, screen focus (the cursor is moved) to that textbox. Scenario 2: The "specify Other" text box is hidden until the user clicks on the Other Radio button. Upon doing so, the textbox is made visible and the cursor is placed in this textbox. Which scenario do you feel is a better approach? Perhaps you have another variation? Please state your reasoning. I would also appreciate it if you could make a generalized statement as to when hiding is better than disabling or vice versa, but I am also interested in this particular example. Thanks. Afetrthought: Perhaps, in the 2nd example, the "Please Specify" text would only appear after the user has selected the 'Other' radio button.

• Android SharedPreferences set True or False - Clear on App Exit

  - by KickingLettuce

  I want a notification to pop up when an app opens. But once User dismisses, I don't want it to come back again, even if they go back to the same activity. But when the app exits, and they come back later, I want same dialog notification to pop up (prompting user to login). So basically... boolean b = true; if (b == true) { // show dialog b = false; } I simply want var b to save state but clear on exit.

• How to evaluate "enterprise" platforms?

  - by Ran Biron

  Hi all, I'm tasked with evaluating an "enterprise" platform for the next-gen version of a product. We're currently considering two "types" of platforms - RAD (workflow engine, integrated UI, small cores of "technology plugins" to the workflows, automatic persisting of state...) like SalesForce.com / Service-Now.com and "cloud based" (EC2 / AppEngine...). While I have a few ideas on where to start, I'd like your opinions - how would you evaluate platforms for an enterprise suite of products? What factors would you consider? How would you eliminate weak options quickly enough to be able to concentrate on the few strong ones? Also interesting is how would you compare enterprise RAD (proven technology, quick to develop - but tends to look "the same as the competition") to cloud-based technology (lots of "buzz", not that many competitors - easy to justify to management, but probably lacking (?) enterprise tools and experience). As said before - I have a few ideas, but would like to see some answers before I post mine so I wouldn't drive the discussion to a specific place. RB.
