• Visual Studio Symbols stored/loaded from wrong place

  - by werty0u

  Hello, I'm rather new to symbol servers and I've been experimenting with them and Visual Studio 2008 running Windows XP(SP3). I've encountered a wierd problem as my symbols are not being cached locally in the directory I've specified all the time. The possible reasons I have found for this si that the symbols(.pdb's) are being written to VS's IDE directory and/or the symbols are somehow being written in with the .exe, which I find odd since it should be read only. The symbols are being sent to the "server" I've specified so that part of the system shouldn't be the problem. Has anyone else had this type of issue before and/or maybe a solution to this problem? Thanks :)

• GAE and Socket Data

  - by Vinod

  I have a field device which keeps on sending data over to any designated port using sockets. I am planning to use GAE for server-side infrastructure. I read GAE does not support sockets. But i can configure the device to send the data over port 80. so we wrote a genericservlet to capture this data on GAE. But it is not obtaining any values from the client. any suggestions to fix this issue?

• "autotest/rails [...] doesn't [...] exist. Aborting"

  - by Ethan

  I'm finding that autotest has stopped working... $ autotest loading autotest/rails Autotest style autotest/rails doesn't seem to exist. Aborting. According to this blog post, the common reason for this error is that people don't have the autotest-rails gem installed. However, I definitely have that installed: autotest-rails (4.1.0) ZenTest (4.1.4, 4.1.3, 4.1.1, 4.0.0, 3.11.1, 3.11.0, 3.10.0, 3.9.3, 3.9.2) I haven't installed any new gems today or yesterday, though I might have done a gem update yesterday. Another issue I saw mentioned was incompatibility with Ruby 1.9, but I'm using MRI Ruby 1.8.6.

• Replacement for Azure SDK Powershell commandlets for deployments

  - by Frank Rosario

  Hi, We've run into an issue with the New-Deployment Azure Powershell commandlet timing out; we've put in a bug report with MS. While they gave us an explanation for it (the path and timeout threshold used to upload through commandlets is different then what's used by the web portal); they don't have a fix for us. We need to get this running so we can automate our build deployments, so we're looking into developing a custom commandlet to replace New-Deployment using the Azure SDK; hoping this path will not have the timeout issues the commandlet did. But before we go down that route; are there any other scriptable tools I can use to replace the New-Deployment functionality? I looked at Cloudberry for Windows Azure; but that doesn't have a scriptable interface yet. Any constructive input is greatly appreciated.

• Syncing with Address Book: Last modified property in ABPerson/ABRecord

  - by Oliver

  I'm syncing data from the Address Book into a Core Data database and I've nearly got it working perfectly. The only issue remaining is checking for changes and modifications on startup and reflecting the changes inside Core Data. Currently, I simply check the ID of each ABRecord and see if it is already in Core Data. Of course, this only works in the case of new contacts and not changed information inside an existing contact. One solution would be to go through each contact already in the database and check each property against the Address Book. The down side of this is that it's really slow. One method that would work is if the ABRecord had a last modified date. I could then store the date inside the Core Data database and check on startup to see if I need to update the contact. However, I can't find anything like this in the documentation. Any ideas?

• Linq to sql Incorrect varchar length

  - by scott

  I have a table with a nullable varchar(50) column in it. When I am updating the value through linq to sql and trace the call in profiler it is defining the parameter as varchar(36). This is obviously causing some minor issues when we are trying to insert data that is between 37 and 50 characters long. I have tried removing the table and re-adding it to the design surface but the same thing happens. I also tried removing that property and adding it manually, same issue. When I look at the designer.cs code it shows the attribute properly: [Column(Storage="_Name", DbType="VarChar(50)")] I am out of ideas, anybody seen this before? Every other column is correct.

• minimum enclosing rectangle of fixed aspect ratio

  - by Ramya Narasimha

  I have an Image with many rectangles at different positions in the image and of different sizes (both overlapping and non-overlapping). I also have a non-negative scores associated with each of these rectangles. My problem now is to find one larger rectangle *of a fixed (given) aspect ratio* that encloses as many of these rectangles as possible. I am looking for an algorithm to do this, if anyone has a solution, even a partial one it would be helpful. Please note that the positions of the rectangles in the image is fixed and cannot be moved around and there is no orientation issue as all of them are upright.

• How to get width of a div in pixels using JQuery (IE)

  - by Casidiablo

  Hello there. At first glance it sounds easy... when using JQuery one can use the .width() method to retrieve the width of an element. The problem comes when the DIV element does not have its size in pixels but in words like 'auto' or 'inherit'. When I do this it works nice in Firefox and Chrome even if the size is specified in words: alert($('#id_div').css('width')); // these two sentences does not It returns something like: 96px. But, IE returns the word 'auto'. I need to know the size it has in pixels because I have to do some calculations with that number... so, I've been wondering how to solve this problem. How can I solve this issue? Thanks for reading.

• jQuery - want to get input value for submit but it gets one and repeats

  - by jquery n00b

  I'm trying to replace all submit buttons with a span so cufon will work. The input still needs to be there so have done some css to hide it and overlay to span on top. My issue is getting the value from the input tag is proving quite diffcult. The code below gets the first input value (being 'search' from the search box at the top of the page, and then puts that value into all the spans, even for buttons that have different values (eg: send). This is a .NET page so the whole page is wrapped in one form tag. Any help is greatly appreciated. jQUERY: jQuery(document).ready( function() { jQuery(".button-wrap input.button").each(function() { var values = jQuery(".button-wrap input").attr('value'); jQuery(this).before("<span class='input-replacer'>" +values+ "</span>"); });

• Why is the CoreData stack in XCode's CoreData enabled template treated as private?

  - by rob5408

  In regards to XCode templates with CoreData enabled, I've read http://stackoverflow.com/questions/2729055/unclear-use-of-property-in-window-app-using-core-data which goes over the 'what' in the templates. But I am having an issue with the 'why'. By declaring the category in the implementation file, the CoreData accessors act like private methods. The problem with that is whenever you want to use CoreData elsewhere in your app, you need some extra code. I've figured you need to either supply your own method that exposes the managed object context, such as... - (NSManagedObjectContext *)getManagedObjectContext { return self.managedObjectContext; } ...which will allow other parts of your app to use it. Or you would need to jam pack your app delegate with specific methods to return managed objects, ie getProducts or setUser. Can anyone shed light on the reasoning here?

• IIS7 or .Net 301 Redirects from 1 domain to another

  - by RandomBen

  I have 2 domains. For the question, I will call them www.old.com and www.new.com. Both urls are pointing to the same IIS7 Site instance. I need to it up so that when someone goes to www.old.com they get a 301 redirect to www.new.com. The tricky part is I am using URL rewrites for pages within the site. So www.old.com/About.aspx redirects to www.new.com/About. To get that to work with IIS7 URL rewrite rules, it also means that www.new.com/About.aspx redirects to www.new.com/About. That is fine and is not a big deal. My issue is how do I redirect the main domain without losing the URL Rewrites from the sub pages? I don't care if I use a module within IIS7 or if I need to do it in .NET code.

• ASP.NET - Themes and Relative Referencing

  - by user70192

  Hello, I have an ASP.NET application that uses themes. Let's pretend I have a theme named "MySkin". I have a page that is in a sub-directory of my application. When I reference a page that uses "MySkin", I noticed that ASP.NET renders a link element that walks up to the root of the site and then down into the App_Themes directory. Here is an example link element I found in a rendered ASP.NET page: <link href="../../App_Themes/MySkin/theme.css" type="text/css" rel="stylesheet" /> Is there a reason that the rendered link element does not use the following instead: <link href="/App_Themes/MySkin/theme.css" type="text/css" rel="stylesheet" /> Is this a browser compatibility issue or is there another reason? The reason I am asking is because I am rendering my ASP.NET page using Server.Execute and storing the result in a different directory. Because of this, I would prefer to use the second way to reference my theme's css. Thank you!

• IIS7 integrated mode closing token between requests

  - by user607287

  We are migrating to IIS7 integrated mode and have come across an issue. We authenticate using WindowsAuthentication but then store a reference to the WindowsPrincipal so that on future requests we can authorize as needed against AD. In IIS 7 Integrated mode, the token is being closed (between requests) so that when we try to run IsInRole it generates a disposed exception. Is there a way to cache this token or change our use of WindowsPrincipal so that we don't need to make successive AD requests to get it for each authorization request? Here is the exception being thrown from WindowsPrincipal.IsInRole("") - System.ObjectDisposedException: {"Safe handle has been closed"} Thanks.

• How to send html form data from one form to multiple database tables

  - by user1701556

  I am able to send html form data to database using hibernate. I am using mySQL, Hibernate, Java 1.6, Spriong 3.0. But I would like to send that same data to multiple tables in the database. My issue is that I want to use only one html form not multiple html form. I have these tables: name, address, email, login, phone_num. From this one html form I want data to go to different tables depending on what the data is. I want to do it using Hibernate so that I am not manually taking form data and inserting it in the database. Please let me know if this is possible.

• Best practice for Python Assert

  - by meade

  Is there a performance or code maintenance issue with using assert as part of the standard code instead of using it just for debugging purposes? Is assert x >= 0, 'x is less then zero' and better or worse then if x < 0: raise Exception, 'x is less then zero' Also, is there anyway to set a business rule like if x < 0 raise error that is always checked with out the try, except, finally so, if at anytime throughout the code x is < 0 an error is raised, like if you set assert x < 0 at the start of a function, anywhere within the function where x becomes less then 0 an exception is raised?

• shall I move from prototype to jquery?

  - by opensas

  lastly I've been feeling like jquery is slowly becoming the defacto standard in js libraries I might be wrong!) or at least that is more active than the rest of the frameworks... for example I've been looking for a fine open source calendar like componente and found http://fullcalendar.vinsol.com/ we've been using prototype for very little things, like its selector capabilities ($ function as a shortcut for document.getElementById, mainly), executing some piece of js when the page is loaded and to issue some very simple ajax calls. so I guess the migration should be quite straight forward, but I'd like to know the pros / cons of migrating to prototype... on the other hand, I guess that having both of them together is not a good choice, specially taking into account that the migration should be quite simple... am I right? saludos sas

• Explanation of contribute_to_class

  - by anon.

  I'm attempted to extend code, and have come across an issue, I don't understand a line of code. I know the outcome of it - but I don't understand how it happens and am naturally enough scared to change it. The line of code I've come across is this: MyGenericRelation().contribute_to_class(model, 'field_name') The result of this code is a field with 'field_name' is added to the 'model' and from what I gather the objects inside the field are a list of type X (part of MyGenericRelation). I'm wondering if anyone can explain how this works. As in, why do I get a list of X objects attached to 'field_name' and if does it have to be generic relations prior to contribute_to_class or would using an actual model type, say 'Y' just give me a list of Y's. To be honest, I am more interested in the affect and functionality of the contribute_to_class method.

• XNA Class Design with Structs as Properties and issues because they are value types and not referenc

  - by Nate Bross

  I'm wondering how you'd recommend designin a class, given the fact that XNA Framework uses Struct all over the place? For example, a spite class, which may require a Vector2 and a Rectangle (both defined as Struct) to be accessed outside of the class. The issue come in when you try to write code like this: class Item { public Vetor2 Position {get; set;} public Item() { Position = new Vector2(5,5); } } Item i = new Item(); i.Positon.X = 20; // fails with error 'Cannot modify the return value of Item because it is not a variable.' // you must write code like this var pos = i.Position; pos.X++; i.Position = pos; The second option compiles and works, but it is just butt ugly. Is there a better way?

• Why does having a transitional doctype, cause my javascript to fail in WebKit and Opera Browsers

  - by morgenmuffel

  Hi all I am trying to get a mouseover script to work, when there is no doctype set the script works fine in all browsers I test, but the site looks like a dogs breakfast However When i set the doctype to transitional (it has to be this doctype) Firefox and IE8 (&compat mode) work fine But Opera and the webkit browsers can only display the popup above the page fold, so if you scroll down the page and go over an image the popup appears above the visible page. And I can't figure out why, there are a couple of instances of document.all in the code, but my attempts to replace these have broken the code, besides the fact it works in Firefox and not Opera makes me think that document.all is not the issue Any help would be appreciated, even just telling me why a doctype would effect Javascript would be a help. Here is the site without a doctype As I can't post 2 links, being a new user and all, follow the link above and change and change the url from noodle3 to noodle to see the site with a doctype

• Asp.net Site on GoDaddy Loads Slowly

  - by Randy

  I just published a very small site to GoDaddy that I programmed in Microsoft Visual Web Developer 2008. The site only contains 6 sheets, none of which are data intensive. Each has a few small images that serve mostly to navigate to the other sheets. There is no data, no SQL, nothing like that. There is one master page that governs the page layout for all of the pages. Everything works fine, for the most part. I am posting because the site loads quite slowly, particularly considering how little content is being loaded. Can anybody give me any advice about what I should look at to speed this thing up a little bit? Is this an asp.net issue? Use of master pages? Godaddy? Something else? I'm a newbie, so speak slowly. Thanks.

• How to reduce java concurrent mode failure and excessive gc

  - by jimx

  In Java, the concurrent mode failure means that the concurrent collector failed to free up enough memory space form tenured and permanent gen and has to give up and let the full stop-the-world gc kicks in. The end result could be very expensive. I understand this concept but never had a good comprehensive understanding of A) what could cause a concurrent mode failure and B) what's the solution?. This sort of unclearness leads me to write/debug code without much of hints in mind and often has to shop around those performance flags from Foo to Bar without particular reasons, just have to try. I'd like to learn from developers here how your experience is. If you had previous encountered such performance issue, what was the cause and how you addressed it? If you have coding recommendations, please don't be too general. Thanks!

• How to change font size in a pickerview?

  - by user183804

  I'm fairly new to iPhone programming and am trying to implement a double-component PickerView. At this point the picker works fine in terms of taking user input, created with Interface Builder. However, I need to change the font size to accommodate the text length in each column. I very much would appreciate any link to a straightforward method to creating a multi-component picker with an adjustable font size. Seems like it is not possible if Interface Builder is used to create the picker. So far I have not found any code links that address this issue in detail. Thanks in advance.

• Dashboard pattern: HorizontalScrollView with pagination or ScrollView?

  - by Macarse

  I am starting a new application and I am willing to use the Dashboard pattern. For example: The Google IO app uses it: My issue is that the amount of buttons will be more than six. I'm not sure if I should use vertical or horizontal scrolling. Vertical scrolling could be done with a ScrollView or a GridView but I am not sure which would be the easier way to implement the horizontal version. I was thinking of using an HorizontalScrollView but it doesn't have pagination. It should feel similar to the tweetdeck app. How would you implement it?
