  • Possible to have empty values with Html For Helpers such as Html.TextBoxFor()?

    - by chobo2
    Hi Is it possible to have to make a html for helper in asp.net mvc 2.0 have a default value of "empty string" Like if I do this Html.TextBoxFor( u => u.ProductName) would render to <input id ="ProductName" name="ProdcutName" type="text" value="Jim" /> Now I don't want the textbox to display jim. I want it to display nothing. <input id ="ProductName" name="ProdcutName" type="text" value="" /> I tried to do this Html.TextBoxFor( u => u.ProductName, new { @value = " "}) but that seems to do nothing. So how can I do this. I hope you can do something like this otherwise I think these new helpers have a great flaw since now I need to use like javascript to remove them since I hardly ever want a default value in the textbox especially when I have a label right beside the textbox saying what it is.

  • What was the motivation for adding the IPV6_V6ONLY flag?

    - by Jeremy Friesner
    In IPv6 networking, the IPV6_V6ONLY flag is used to ensure that a socket will only use IPv6, and in particular that IPv4-to-IPv6 mapping won't be used for that socket. On many OS's, the IPV6_V6ONLY is not set by default, but on some OS's (e.g. Windows 7), it is set by default. My question is: What was the motivation for introducing this flag? Is there something about IPv4-to-IPv6 mapping that was causing problems, and thus people needed a way to disable it? It would seem to me that if someone didn't want to use IPv4-to-IPv6 mapping, they could simply not specify a IPv4-mapped IPv6 address. What am I missing here?

  • Parser Error Debugging VS2008

    - by maatthias
    When I create new VS2008 asp.net application it builds fine. But when I start debugging I get below error in browser. I've rebuilt the app. The Inherits clause of the markup page matches the class in the code-behind C#. Any clues? Server Error in '/' Application. Parser Error Description: An error occurred during the parsing of a resource required to service this request.

  • Client Side Prediction

    - by user13842
    I have a question regarding Client Side prediction. Ive tried to search topics about my specific problem but couldn't find anything which really answered my problem. Most tutorials and explanations assume that the Client sends messages like "Move my player up by 1 Position", but what if i send messages like "Set my player's velocity to x"? Since it's hard to explain with text, i made a graphic explaining my problem. The main problem is, that the player sets his own velocity, due to Client Side Prediction, earlier than the Server. So if 2 different velocities overlap, the Server would get out of sync. How can i tackle that problem? Thanks a lot. Graphic: http://img27.imageshack.us/img27/6083/clientpred.png (Ignore the 5.5cm)

  • Alter Git prompt on Windows

    - by kko
    I'm using Git on Windows, installed through GitExtensions with MSysGit (latest) having selected "do not modify my Windows prompt" during installation. Now, I would like to be able to modify the default prompt (which by default shows just the branch name to also show me how much time, and how many local commits since I last pushed to origin (or specifically origin/master, whichever is easier). So say instead of: me@myPC /c/myRepo (master) I would see something along the lines of: me@myPC /c/myRepo (master) 5 | 10:20 meaning I have last pushed 10h 20min ago and I have made 5 local commits since. Before you mention it, I am aware there are ways of doing it with PowerShell, but I don't want to use it. I want my standard git bash we all know and love. I found a few solutions to that, with modifying PS1 variable in .bashrc file, but (excuse my poor Unix konwledge) they seem to be not working, (for example accepted answer to this question). So there you have it. Is this possible?

  • Is there a way to use a dictionary or xml in the Application Settings?

    - by Shimmy
    I have to store a complex type in the application settings. I thought that storing it as XML would work best. The problem is I don't know how store XML. I prefer to store it as a managed XML rather than using just a string of raw XML having to parse it on each access. I managed to set the Type column of the setting to XDocument, but I was unable to set its value. Is there a way to use XDocument or XML in application settings? Update I found a way, simply by editing the .settings file with the xml editor. I changed it to a custom serializable dictionary, but I get the following error when I try to access the setting-property (I set it to a serialized representation of the default value). The property 'Setting' could not be created from it's default value. Error message: There is an error in XML document (1, 41). Any ideas will be appreciated.

  • Can I use a local::lib if local::lib isn't installed globally and without eval-ing it in shell?

    - by xenoterracide
    I have a problem, I want to use local::lib; in a script. But because I need to use this script many places, I don't want to try adding the eval to bashrc, every time I install this script to a server. and I can't get local::lib installed globally (in the default @INC) on the servers. Is there any way I can use local::lib from within the script so that it knows where the module local::lib is without the eval that local::lib recommends and without installing it into a directory in the default @INC on the server?

  • How are managed the sequences by JPA and Hibernate?

    - by romaintaz
    Hi all, I am using Hibernate in my project, and many of my entities use a sequence for their technical keys. For example: @Entity @Table(name = "T_MYENTITY") @SequenceGenerator(name = "S_MYENTITY", sequenceName = "S_MYENTITY") public class MyEntity { @Id @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "S_MYENTITY") @Column(name = "MY_ENTITY_ID") private Long entityId; ... } I have two questions about the ID generated by Hibernate when a new object of this class is persisted: Why SequenceGenerator (from javax.persistence) has a default value of allocationSize set to 50 instead of 1? What are the interests of that? What is the default algorithm used by Hibernate to calculate the generated ID? It seems that Hibernate uses the value returned by the sequence hosted by my Oracle database, but then modify it before assigning it to my entity...

  • iPhone App takes up too much memory

    - by Stephen Furlani
    Ok, so here's my problem. My iPhone app is 1.2MB on disk. Granted I have a bunch of Images for the GUI buttons and backgrounds, etc. In-memory, my app takes up a whopping 15MB! That means if I then take a picture with the camera, 8MB default, it gives a memory warning (several) even before the picker calls its delegate! How can I tell what is grabbing so much memory, and how to remove it? I've removed all of my debugging symbols and added [-Os], but it still takes up a huge amount of memory! Also, (how) can I change the default resolution of the camera?

  • C++ linkage error . What am I doing wrong ? [migrated]

    - by nashmaniac
    So, this is the first time I actually separated a single program into a header and two .cpp files . But I think I am getting an linkage error . Heres how the directory looks . (heres a link to my image I dont have enough rep to post image in the question) http://i.stack.imgur.com/sbT4V.png The main.cpp is my main source file where all the calling functions and other important stuff goes . In functions.cpp I have all my functions , in the coordin.h file I have the function prototypes and structures and Constants . Everything is ok no typo nothing I have checked everything . But I am getting an undefined reference to function error. I have included the coordin.h file too . Do you think the functions.cpp file needs to go somewhere else I mean is the compiler not looking inside that file ? Thanks !

  • Cannot see index view of my controller - routing related

    - by olst
    Hi. I have a controller named Content, which has an Index action, which is associated with a view. I would like the simple route "content" to show me the index view of the content controller, so I use the following code (with the addition of the default site home route): routes.MapRoute( "ContentIndex", "content", new { controller = "Content", action = "Index"} ); routes.MapRoute( "Default", "{controller}/{action}", new { controller = "Home", action = "Index" } ); when I type the url : "http://localhost/content/", I get an error 404 saying the resource cannot be found, but when I type "http://localhost/content/index", it shows the content index view. How can I get rid of the index in the url ? Thanks !

  • How to implement custom texture formats in Android?

    - by random1337
    What I know: Android can load PNG, BMP, WEBP,... via BitmapFactory. What I want to achive: Load my own 2D file format (e.g. 1-bit texture with a 1-bit alpha channel) and output a RGBA8888 texture. Question: Is there any interface to achieve this?(or any other way) The resulting image is used as a texture for a 3D model. Why would you do that? Saving phone memory and download bandwidth while expanding the texture at runtime to RAM seems reasonable for very simple textures.

  • Ubuntu One slow download sync speed

    I am having problems syncing my Ubuntu One files with my Ubuntu 12.04 fresh installation. Everything went well during the setup phase. Now, I am trying to sync back in my folders in my U1 account and the transfer speed is extremely slow. I am averaging a 15kb/s transfer speed. I tried uninstalling ubuntuone-client and reinstalling it. It did not fixed the problem. Right now U1 is stuck downloading a 50mb file. It is taking forever. Any ideas?

  • Leaving SQL Management open on the internet

    - by Tim Fraud
    I am a developer, but every so often need access to our production database -- yeah, poor practice, but anyway... My boss doesn't want me directly on the box using RDP, and so we decided to just permit MS SQL Management Console access so that I can do my tasks. So right now we have the SQL box somewhat accessible on the internet (on port 1433 if I am not mistaken), which opens a security hole. But I am wondering, how much of an uncommon practice is this, and what defaults should I be concerned about? We use MSSQL2008 and I created an account that has Read-Only access, because my production tasks only need that. I didn't see any unusual default accounts with default passwords on the system, so I would be interested to hear your take. (And of-course, is there a better way?)

  • 13.10 login Background without unity

    - by user204477
    I want to change my login screen background (and keep the dots). But I upgraded to cinnamon 2.0 a day ago and then to 13.10 earlier today. I recently became aware of the issue with cinnamon 2.0 and unity on 13.10. This normally would not matter to me since I use cinnamon instead but the only way I know of to change the login screen background is to change unity background. Also all of my backgrounds are jpgs not pngs (in case anyone was gonna say the replace /usr/share/backgrounds/ubuntu-warty.png) and for some reason gimp has issues so converting them is not currently possible for me.

  • How do I open a web browser from C#? Process.Start() isn't working?

    - by Scott Whitlock
    I have a URL and I want to launch it in the default browser. I've tried two methods: Process.Start("http://stackoverflow.com"); ... and the one detailed in this other question using ShellExecute. In both cases I get the error: Windows cannot find 'http://stackoverflow.com'. Make sure you typed the name correctly, and then try again. It shouldn't be trying to open it as a file though... from what I understand, it should recognize it as a URL and open it in the default browser. What am I missing? By the way: OS = Vista, and .NET = 3.5

  • Creating attribute sets and attributes programatically magento

    - by digital_paki
    I am using the code listed on the following link =: http://www.magentocommerce.com/wiki/5_-_modules_and_development/catalog/programmatically_adding_attributes_and_attribute_sets Everything works until the point: // Just add a default group. else { $this->logInfo("Creating default group [{$this->groupName}] for set."); $modelGroup = Mage::getModel('eav/entity_attribute_group'); $modelGroup->setAttributeGroupName($this->groupName); $modelGroup->setAttributeSetId($id); // This is optional, and just a sorting index in the case of // multiple groups. // $modelGroup->setSortOrder(1); $model->setGroups(array($modelGroup)); } I am unsure where the object reference would need to be set from - I am attempting to have this as a separate file that can be automated - I am running this file by doing a require_once 'app/Mage.php'; Mage::app(); Any help in this would be greatly appreciated Thanks

  • Assign TableView column binding to a specific core-data object in to-many related entity based on se

    - by snown27
    How would I assign a column of a TableView to be a specific entry in a Core Data entity that is linked to the NSArrayController via a to-many relationship? For example Entity: MovieEntity Attributes: title(NSString), releaseDate(NSDate) Relationship: posters<-->> PosterEntity Entity:PosterEntity Attributes: imageLocation(NSURL), default(BOOL) Relationships: movie<<--> MovieEntity So I have a three column table that I want to display the Poster, Title, and Release Date attributes in, but as one movie could potentially have several different style's of posters how do I get the poster column to only show the one that's marked default? Since the rest of the table is defined in Interface Builder I would prefer to keep it that way for the sake of keeping the code as clean as possible, but if this can only be done programmatically then I'm all ears. I just wanted to give preference in case there's more than one way to skin a cat, so to speak.
