  • Is it possible to supply the jQuery Validation plugin with a rules object?

    - by ethagnawl
    I took the rules that I'd been using to validate my form and broke them out into a JSON object, hoping to use the same set of rules for client/server validation. So, where I had: $(document.getElementById('new_listing_form')).validate({ rules: { apt: { required: true } } }); I'm attempting to use: var rules_obj = { apt: { required: true } }; $(document.getElementById('new_listing_form')).validate({ rules: rules_obj }); ... and the form is not being validated. Does anyone know if this is possible?

  • In C, is it possible do free only an array first or last position?

    - by user354959
    Hi there! I've an array, but I don't need its first (or last) position. So I point a new variable to the rest of the array, but I should free the array first/last position. For instance: p = read_csv_file(); q = p + 1; // I don't need the first CSV file field // Here I'd like to free only the first position of p return q; Otherwise I've to memcpy the array to other variable, excluding the first position, and then free the original array. Like this: p = read_csv_file(); q = (int*) malloc(sizeof(int) * (SOME_SIZE - 1)); memcpy(q, p+1, sizeof(int) * (SOME_SIZE - 1)); free(p); return q; But then I'll have the overhead of copying all the array. Is this possible to only free a single position of an array?

  • Possible to load entries into hosts.deny from text file?

    - by Tar
    I have around 96 million IP addresses that I have collected and routinely validate to be VPN providers, proxies, etc. I want these blocked. Currently, I am including the list formatted like deny ip; in nginx and that works perfectly. I want to use this list on another server, but nginx isn't an option, and I don't trust apache to handle this without slowing down. Is there a way to load this list into hosts deny via some command like aclexec or something? Are there other alternatives like setting up a DNSBL or using hosts.deny in conjunction with one?

  • What are possible results/side effects if replication between DC's in a Windows domain is unable to occur?

    - by hydroparadise
    There's plenty of administration literature out there how to properly manage Windows servers. But in dealing with real life, things don't always occur like you want them to. In Microsoft's Windows Server 2003 Administrator's Companion, out of 1400+ pages, theres only one page that I could find when it comes up setting up additional domain controlers. They make it sound seemless and don't reveal a whole lot on what happens if "peer" DC's are unable to replicate. Down to the specific issue at hand, we had a DC go down about a month ago due to a bad RAID controller. There was nothing critical that waranted imediate attention, so bringing it back up got put on the back burner. A month later, we get the DC back up and running and everyting seemed ok. The next day, nobody is able to logon complaining that the "user does not exist" or "unable to establish a trust relationship". Knowing that I had just put the downed DC back on the network, I immediately took it back off the network and had everybody restart the workstations. After that, exchange was fine, shares became available, and everybody was able to log in. After doing some event log swimming, it would appear that everything started due to replication issues on the SYSVOL. I've read where you can force replication, but that would mean putting it back on the network. I am afraid to put the DC back on the network in fear that something else could go wrong. So, what other issues could one expect to run into where two DC's are unreplicated for over a month?

  • Is it possible that an insert would use parallelism?

    - by Lieven Cardoen
    In what situation can inserting a simple record (the table has got some 10 columns, two of them are xml) use parallelism? CREATE TABLE [dbo].[PackageSessions]( [PackageSessionId] [int] IDENTITY(1,1) NOT NULL, [PackageId] [int] NOT NULL, [UserId] [int] NOT NULL, [StartDateTime] [datetime] NULL, [StopDateTime] [datetime] NULL, [Score] [float] NOT NULL, [ScoreMax] [float] NOT NULL, [CompletionStatus] [int] NOT NULL, [ReviewPlayerContextId] [int] NOT NULL, [PlayerContextId] [int] NOT NULL, [ReducedScore] [float] NOT NULL, [ReducedScoreMax] [float] NOT NULL, [PackageSnapShot] [xml] NULL, [InterfaceLanguageId] [int] NOT NULL, [Data] [xml] NULL, [PackageSessionLanguageId] [int] NOT NULL, CONSTRAINT [PackageSessions_PK] PRIMARY KEY CLUSTERED ( [PackageSessionId] ASC )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] ) ON [PRIMARY]

  • Laptop + External Monitor: Possible to Scale Mouse-crossover Position?

    - by Brian Lacy
    I have a laptop with a 16" screen @ 1366x768 resolution, and a 24" external monitor at 1920x1200 resolution. I'm extending the Windows 7 desktop onto the other screen. The 24" is the secondary monitor, and is positioned so the bottom of that screen lines up with the bottom of the 16" screen. Currently, if I move the mouse to the top portion of the 24" screen, then move left, the mouse will stop at the edge of the 24" screen until I move it down far enough to get into the range of the 16" screen. So that's all pretty standard; but I'm wondering if there's any software out there that will allow me to "scale" the mouse-crossover position, such that if I'm at the TOP of the 24" screen and move left, the mouse will cross to the TOP of the 16" screen, whereas if I'm at the BOTTOM of the 24" screen, crossing over will position the mouse at the BOTTOM of the 16" screen. So then, if the mouse cursor is on the 24" screen at (x,y) position (10,600), and I move 20 pixels left, the mouse is now on the 16" screen at position (1356,384). Anyone know of such a solution?? Note: I also use Ubuntu, so if there's a solution to this for X, but not Windows, I'd be interested in that also.

  • C# TabControl - is it possible to "disable" individual TabPages?

    - by CaldonCZE
    Is it somehow possible to disable one (or more) tabs of tab control? At some point I need to make user stay on the active tab and prevent him from leaving... I know I can disable the whole TabControl component, but that disables also all components on active tab... I also tried to use the Selecting method of TabControl: private void TabControl_Selecting(object sender, TabControlCancelEventArgs e) { e.Cancel = PreventTabSwitch; } This works, prevents user from switching (if PreventTabSwitch==true), but since all tabs look active and just don't react it's confusing... There is no Enabled property for individual tab pages, so I don't know what else to do... Thanks a lot for in advance for all tips.

  • Is it possible to get Logged in user Non Restricted token from a service on Vista?

    - by coolcake
    Hello All, I need to create a process with integrity level high, so that it can do all the administrative tasks. But the created process should run in the current logged in desktop i.e. it should not run in session 0. By default only administrators will log on to the console. The service should launch the process, as service is running in session 0 and system account. Can it any how get the non restricted token and use it in CreateProcessAsUser, so that the process created does have integrity level of high or system. Is it possible? One more thing is i should get the non restricted token with out prompting for user name or password of the logged in user. Thanks

  • Is it possible to do a web search filtered for the user's comprehension level? [migrated]

    - by Tim
    Do any of the major search engines support a filter to indicate the comprehension level of the user and thus to filter out content beyond their scope? So for example, if someone wanted to find results on "astronomy", but to only show content appropriate for someone in junior-high or lower. Alternatively, if there isn't such an existing method directly, any ideas on how this might be accomplished with existing tools? I found this paper, which seems to indicate folks have looked at this, just don't know if there is a real world tool to do this.

  • Inheritance: possible to change base reference to something else?

    - by fred
    For example I have two classes, Base and Derived as shown below: class Base { public string Name { get; set; } public Base() { } } class Derived : Base { public Derived(Base b) { base = b; // doesn't compile, but is there any way to do something similar? } } So that they behave like this: Base b = new Base(); b.Name = "Bob"; Derived d = new Derived(b); d.Name = "John"; // b.Name is now "John" also Is this possible? I guess one way would be to keep the Base b reference in Derived and override Derived.Name to point to b.Name? Is there an easier way though, for example if I have like 50 properties to override? class Derived : Base { Base b; public override string Name { get { return b.Name; } set { b.Name = value; } } public Derived(Base b) { this.b = b; } }

  • Using C++ is a Linked-List implementation without using pointers possible or not?

    - by sonicoder
    My question is very simply, can one using C++, implment a link-list data structure without using pointers (next nodes)? To further qualify my question, I'm mean can one create a Linked-List data structure using only class instantiations. A common node definition might be like so: template<typename T> struct node { T t; node<T>* next; node<T>* prev; }; I'm aware of std::list etc, I'm just curious to know if its possible or not - and if so how? code examples will be greatly appreciated.

  • Possible reasons for high CPU load of taskmgr.exe process on VM?

    - by mjn
    On a VMware virtual machine which has severe performance problems I can see a constant average of 20+ percent CPU load for the TASKMGR.EXE (task manager) process. The apps running on this server have lower load, around 4 to 10 percent average. The VM is running Windows 2003 Server Standard with 3.75 GB assigned RAM. I suspect that the task manager CPU load has something to do with other VM instances on the VMWare server but could not see a similar value on internal ESXi systems (the problematic VM runs in the customers IT).

  • How can I use multiple PHP header content types on the same page? is this possible?

    - by Jon
    Is it possible to use multiple header types in one document? For example: header("Content-type: image/jpeg"); header('Content-Type: text/html; charset=utf-8'); returns the whole page as text/html... while header('Content-Type: text/html; charset=utf-8'); header("Content-type: image/jpeg"); Returns the whole page as an image.... How can I use both types of content on the same page? I'm using ob_start() at the top and ob_end_flush() at the beginning.

  • Is it possible to autocomplete fields in Sharepoint with user info?

    - by Antoine
    Hi, I'm in charge of a Sharepoint collection, and a user asks this. Is it possible that when a user creates an item, some fields are automatically filled with some info, such as email address and location? Authentication uses Active Directory, so every user is identified when using Sharepoint. The only issue is that, being in a big corporate company, I don't have any access to the server, so it must be feasible through configuration of said site/list or using Sharepoint Designer, but I can't and won't be allowed to deploy anything server side. Any idea?

  • Accessing php $_SESSION from python (wsgi) - is it possible?

    - by Bill Zimmerman
    Hi, I've got a python/WSGI app which needs to check to see if a user has logged on to a PHP web app. The problem is that the PHP app checks if a user has logged on by comparing a value in the $_SESSION variable to a value in the cookie from the user's browser. I would prefer to avoid changing the behavior of the php app if at all possible. My questions: Is there anyway I can access the session variables from within python? Where should I start to look? Are there any obvious security/performance issues I should be aware of when taking this approach?

  • Is it possible to run a hidden console application from a Windows service?

    - by norgepaul
    I've written a server in Delphi 2010 that needs to launch a console application every now and again to back up a database. The console application can send log information to the console window, but it is not required. This works fine when running as an application, but when run as a service I get an access violation when launching the console application. This is the case even if I launch it hidden (SW_HIDE). Is it possible to launch a hidden console application from a Windows service? The solution needs to work on XP, Vista and Windows 7.

  • Is it possible to create a jdbc connection without a password (using postgresql 'trust')?

    - by mojones
    I am using jdbc to connect to a postgresql database in a java application (actually the app is written in Groovy). I have postgresql set up to use the 'trust' authentication method. Is it possible to open a jdbc connection without specifying a password?

  • Is it possible to specify a return type of "Derivative(of T)" for a MustOverride sub in VB.NET?

    - by Casey
    VB.NET 2008 .NET 3.5 I have two base classes that are MustInherit (partial). Let's call one class OrderBase and the other OrderItemBase. A specific type of order and order item would inherit from these classes. Let's call these WebOrder (inherits from OrderBase) and WebOrderItem (inherits from OrderItemBase). Now, in the grand scheme of things WebOrder is a composite class containing a WebOrderItem, like so: Public Class WebOrder Inherits OrderBase Public Property OrderItem() as WebOrderItem End Property End Class Public Class WebOrderItem Inherits OrderItemBase End Class In order to make sure any class that derives from OrderBase has the OrderItem property, I would like to do something like this in the OrderBase class: Public MustInherit Class OrderBase Public MustOverride Property OrderItem() as Derivative(Of OrderItemBase) End Class In other words, I want the derived class to be forced to contain a property that returns a derivative of OrderItemBase. Is this possible, or should I be using an entirely different approach?

  • How many bootable partitions are possible to have on one hard drive?

    - by draiden
    This may not be the correct place to post this; if that's the case, just let me know and point me in the right direction please! I'm thinking of building a box that needs to be lightweight and portable, and would need to be able to boot multiple installations of windows. I am needing to have multiple installations so that I can, for example, plug the box in to the network at one location, boot in to that location's partition, and have full access to everything I would normally need to do on a computer that has already been set up on that network. Then, when I go to the next client, I would be able to do the same thing, with the new location's partition, and have all of those network settings, drive mappings, etc., available there. Obviously I'd need to go through and set them all up on the different locations/networks, I'm not expecting it to magically know where I am and what I'm doing. It would be like I'm carrying around a computer that is configured for each place I need to go in one little box, instead of having to have multiple computers or having to reconfigure all the settings and such every time I go to another client. Or is there an easier way to do this that I haven't learned of?
