  • Opening href in jQuery Dialog

    - by Phil
    Okay, so I've got the following code to create a dialog of a div within a page: $('#modal').dialog({ autoOpen: false, width: 600, height: 450, modal: true, resizable: false, draggable: false, title: 'Enter Data', close: function() { $("#modal .entry_date").datepicker('hide'); } }); $('.modal').click(function() { $('#modal').dialog('open'); }); All working fine. But what I want is to also be able to open a link in a dialog window, kinda like... <a href="/path/to/file.html" class="modal">Open Me!!</a> I've done this before by hardcoding the path: $('#modal').load('/path/to/file.html').dialog('open'); but we can't hardcode the path in the javascript (as there will be multiple coming from the database) and I'm struggling to understand how to get this to work. I'm also pretty sure that the answer is really obvious, and I'm merely setting myself up to be humbled by the clever folk here at StackOverflow, but I've scratched my head for long enough this afternoon, so my ego has been put away, and hopefully someone can point me in the right direction... Thanks Phil

  • How should I handle persistence in a Java MUD? OptimisticLockException handling

    - by Chase
    I'm re-implementing a old BBS MUD game in Java with permission from the original developers. Currently I'm using Java EE 6 with EJB Session facades for the game logic and JPA for the persistence. A big reason I picked session beans is JTA. I'm more experienced with web apps in which if you get an OptimisticLockException you just catch it and tell the user their data is stale and they need to re-apply/re-submit. Responding with "try again" all the time in a multi-user game would make for a horrible experience. Given that I'd expect several people to be targeting a single monster during a fight I think the chance of an OptimisticLockException would be high. My view code, the part presenting a telnet CLI, is the EJB client. Should I be catching the PersistenceExceptions and TransactionRolledbackLocalExceptions and just retrying? How do you decide when to stop? Should I switch to pessimistic locking? Is persisting after every user command overkill? Should I be loading the entire world in RAM and dumping the state every couple of minutes? Do I make my session facade a EJB 3.1 singleton which would function as a choke point and therefore eliminating the need to do any type of JPA locking? EJB 3.1 singletons function as a multiple reader/single writer design (you annotate the methods as readers and writers). Basically, what is the best design and java persistence API for highly concurrent data changes in an application where it is not acceptable to present resubmit/retry prompts to the user?

  • Double type returns -1.#IND/NaN error when calculating pi iteratively

    - by Draak
    I am working through a problem for my MCTS certification. The program has to calculate pi until the user presses a key, at which point the thread is aborted, the result returned to the main thread and printed in the console. Simple enough, right? This exercise is really meant to be about threading, but I'm running into another problem. The procedure that calculates pi returns -1.#IND. I've read some of the material on the web about this error, but I'm still not sure how to fix it. When I change double to Decimal type, I unsurprisingly get Overflow Exception very quickly. So, the question is how do I store the numbers correctly? Do I have to create a class to somehow store parts of the number when it gets too big to be contained in a Decimal? Class PiCalculator Dim a As Double = 1 Dim b As Double = 1 / Math.Sqrt(2) Dim t As Double = 1 / 4 Dim p As Double = 1 Dim pi As Double Dim callback As DelegateResult Sub New(ByVal _callback As DelegateResult) callback = _callback End Sub Sub Calculate() Try Do While True Dim a1 = (a + b) / 2 Dim b1 = Math.Sqrt(a * b) Dim t1 = t - p * (a - a1) ^ 2 Dim p1 = 2 * p a = a1 b = b1 t = t1 p = p1 pi = ((a + b) ^ 2) / (4 * t) Loop Catch ex As ThreadAbortException Finally callback(pi) End Try End Sub End Class

  • Visual studio not detecting that exe is out of date after perforce revert

    - by CHaskell2
    This is a bit of an odd situation. Here's what's happening. So, we have a VS2008 project which outputs to a number of files under perforce control. These files have the always writable flag set. I compile the project in VS, which gives me up to date binaries on my machine. If I then revert those binaries via perforce, I have the version of the binaries that were up on perforce (ie, old ones.) Despite this, compiling the project again at this point detects no changes and will not remake those binaries. In a way, this makes sense, since none of the code or obj files have changed, but it's not really what I want to happen. This comes up in an edge case on our automated build server. I can think of tons of different little hacks I could do to fix this, but I'm thinking I could be missing something fundamental here. The actual build process uses the Unreal build tool, so there is a bit of magic going on behind the scenes that I'm not entirely familiar with too. Edit: This is a C/C++ project, forgot to mention that.

  • Why does this class declaration not work on Visual Studio

    - by Roel
    So I'm trying to get some code that is written for gcc to compile on Visual Studio 2008. I have a problem that I have narrowed down to this: class value_t { public: typedef std::deque<value_t> sequence_t; typedef sequence_t::iterator iterator; }; This code fails: 1>cpptest.cpp 1>c:\program files\microsoft visual studio 9.0\vc\include\deque(518) : error C2027: use of undefined type 'value_t' 1> c:\temp\cpptest\cpptest.cpp(10) : see declaration of 'value_t' 1> c:\temp\cpptest\cpptest.cpp(13) : see reference to class template instantiation 'std::deque<_Ty>' being compiled 1> with 1> [ 1> _Ty=value_t 1> ] 1>c:\program files\microsoft visual studio 9.0\vc\include\deque(518) : error C2027: use of undefined type 'value_t' 1> c:\temp\cpptest\cpptest.cpp(10) : see declaration of 'value_t' However when I try this with std::vector, it compiles fine: class value_t { public: typedef std::vector<value_t> sequence_t; typedef sequence_t::iterator iterator; }; What's wrong? I have tried adding 'typename' everywhere I can think of, but at this point in time I'm thinking it's just a bug in the Dinkumware STL. Can anyone explain what's happening, and/or offer a solution? Thanks.

  • How do DP and CC change in Piet?

    - by Paul Butcher
    According to the specification, Black colour blocks and the edges of the program restrict program flow. If the Piet interpreter attempts to move into a black block or off an edge, it is stopped and the CC is toggled. The interpreter then attempts to move from its current block again. If it fails a second time, the DP is moved clockwise one step. These attempts are repeated, with the CC and DP being changed between alternate attempts. If after eight attempts the interpreter cannot leave its current colour block, there is no way out and the program terminates. Unless I'm reading it incorrectly, this is at odds with the behaviour of the Fibonacci sequence example here: http://www.dangermouse.net/esoteric/piet/fibbig1.gif (from: http://www.dangermouse.net/esoteric/piet/samples.html) Specifically, why does the DP turn left at (0,3) ((0,0) being (top, left)) when it hits the left edge? At this point, both DP and CC are LEFT, so, by my reading, the sequence should then be: Attempt (and fail) to leave the block by going off the edge at (0,4), Toggle CC to RIGHT, Attempt (and fail) to leave the block by going off the edge at (0,2). Rotate DP to UP, Attempt (and succeed) to leave the block at (1,2) by entering the white block at (1,1) The behaviour indicated by the trace seems to be that DP gets rotated all the way, leaving CC at LEFT. What have I misunderstood?

  • WPF designer gives exception when databinding a label to a checkbox

    - by John
    I'm sure it's something stupid, but I'm playing around with databinding. I have a checkbox and a label on a form. What I'm trying to do is simply bind the Content of the label to the checkbox's IsChecked value. What I've done runs fine (no compilation errors and acts as expected), but if I touch the label in the XAML, the designer trows an exception: System.NullReferenceException Object reference not set to an instance of an object. at MS.Internal.Designer.PropertyEditing.Editors.MarkupExtensionInlineEditorControl.BuildBindingString(Boolean modeSupported, PropertyEntry propertyEntry) at <Window x:Class="UnitTestHelper.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:FileSysCtls="clr-namespace:WPFFileSystemUserControls;assembly=WPFFileSystemUserControls" xmlns:HelperClasses="clr-namespace:UnitTestHelper" Title="MainWindow" Height="406" Width="531"> <Window.Resources> <HelperClasses:ThreestateToBinary x:Key="CheckConverter" /> </Window.Resources> <Grid Height="367" Width="509"> <CheckBox Content="Step into subfolders" Height="16" HorizontalAlignment="Left" Margin="17,254,0,0" Name="chkSubfolders" VerticalAlignment="Top" Width="130" IsThreeState="False" /> <Label Height="28" HorizontalAlignment="Left" Margin="376,254,0,0" Name="lblStepResult" VerticalAlignment="Top" Width="120" IsEnabled="True" Content="{Binding IsChecked, ElementName=chkSubfolders, Mode=OneWay, UpdateSourceTrigger=PropertyChanged, Converter={StaticResource CheckConverter}}" /> </Grid> The ThreeStateToBinary class is as follows: class ThreestateToBinary : IValueConverter { #region IValueConverter Members public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) { if ((bool)value) return "Checked"; else return "Not checked"; //throw new NotImplementedException(); } public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) { return ((string)value == "Checked"); //throw new NotImplementedException(); } #endregion } Quite honestly, I'm playing around with it at this point. It was originally simpler (not using the ValueConverter) but was displaying similar behavior when I simply had the content set to: Content="{Binding IsChecked, ElementName=chkSubfolders, UpdateSourceTrigger=PropertyChanged}" Any ideas? Thanks, John

  • Windows-mobile app won't run after being closed by Task Manager

    - by pithyless
    I've inherited some windows-mobile code that I've been bringing up-to-date. I've come across a weird bug, and I was hoping that even though a bit vague, maybe it will spark someone's memory: Running the app (which is basically a glorified Forms app with P/Invoke gps code), I switch to the task manager, and close the app via End Task. Seems to exit fine (no errors and disappears from Task Manager). Unfortunately, the app refuses to start a second time until I reboot the phone or reinstall the CAB. What's worse: this bug is reproducible on a HTC Diamond, but works fine (ie. can run again after EndTask) on an HTC HD2. The only thing I can think of is some kind of timing race between a Dispose() and the Task Manager. Any ideas? I'm also thinking of a workaround - I do have a working "Exit Application" routine that correctly cleans up the app; can I catch the EndTask event in the c# code in order to complete a proper cleanup? Maybe I'm just missing the pain point... all ideas welcome :)

  • Non-deprecated code for detecting whether a SharePoint User has a specific Permission Level

    - by ccomet
    In our application, we have some forms which need to show some data specifically if the current user has a specific permission level. These users belong to an SPGroup which includes users who should not see this data, so in this particular case I cannot filter based off of group membership. My current solution has been to use web.CurrentUser.Roles and use a simple check on whether it contains a permission level of the correct name. Roles is of the deprecated SPRole class, so I am bombarded with warning messages despite the fact it technically works. It suggests that I use SPRoleAssignment or SPRoleDefinition (the recommendation seems arbitrary since some lines recommend one while others recommend the other even though it is being used for the same thing). However, I cannot seem to find any method to directly retrieve an SPRoleAssignment or SPRoleDefinition object from an SPUser or SPPrincipal object, nor can I retrieve either object corresponding specifically to the current user of the SPWeb object. How can I update these methods to use non-deprecated code? I've found other cases of determining user permissions, but I haven't found one that will work from a starting point of the current web or the current user. It's not urgent, but it certainly is helpful to avoid having to sift through all of those warnings just to reach the more important warnings.

  • Nonblocking Tcp server

    - by hoodoos
    It's not a question really, i'm just looking for some guidelines :) I'm currently writing some abstract tcp server which should use as low number of threads as it can. Currently it works this way. I have a thread doing listening and some worker threads. Listener thread is just sits and wait for clients to connect I expect to have a single listener thread per server instance. Worker threads are doing all read/write/processing job on clients socket. So my problem is in building efficient worker process. And I came to some problem I can't really solve yet. Worker code is something like that(code is really simple just to show a place where i have my problem): List<Socket> readSockets = new List<Socket>(); List<Socket> writeSockets = new List<Socket>(); List<Socket> errorSockets = new List<Socket>(); while( true ){ Socket.Select( readSockets, writeSockets, errorSockets, 10 ); foreach( readSocket in readSockets ){ // do reading here } foreach( writeSocket in writeSockets ){ // do writing here } // POINT2 and here's the problem i will describe below } it works all smothly accept for 100% CPU utilization because of while loop being cycling all over again, if I have my clients doing send-receive-disconnect routine it's not that painful, but if I try to keep alive doing send-receive-send-receive all over again it really eats up all CPU. So my first idea was to put a sleep there, I check if all sockets have their data send and then putting Thread.Sleep in POINT2 just for 10ms, but this 10ms later on produces a huge delay of that 10ms when I want to receive next command from client socket.. For example if I don't try to "keep alive" commands are being executed within 10-15ms and with keep alive it becomes worse by atleast 10ms :( Maybe it's just a poor architecture? What can be done so my processor won't get 100% utilization and my server to react on something appear in client socket as soon as possible? Maybe somebody can point a good example of nonblocking server and architecture it should maintain?

  • Update table columns bound to NSArrayController

    - by Loz
    Hi, I'm fairly new to the world of bindings in cocoa, and I'm having some troubles (perhaps/probably due to a misunderstanding). I have a singleton that contains an NSMutableArray called plugins, containing objects of class Plugin. It has a method called loadPlugins which adds objects to the plugins array. This may be called at any point. It's been added as an instance in Interface Builder. Also in IB is an NSObjectController, whose content outlet is connected to the singleton. There is also an NSArrayController, whose contentArray is bound to the NSObjectController (controller key is 'selection', model key path is 'plugins', object class name is 'Plugin'). And finally I have a table view with 2 columns, the values of which are bound to the NSArrayController's arrangedObjects, using keys of properties in the Plugin class. So far so standard (as far as I can tell from tutorials at least). My trouble is that when the loadPlugins method is called in the singleton, and objects are added to the plugins array, the table doesn't update to show the objects (unless loadPlugins is called before the nib is loaded). -reloadData called on the tableView doesn't do anything. Is there a way to tell the NSArrayController that the referenced array has been updated? I understand there is the -add: method for NSArrayController, which could be used in the loadPlugins, but this isn't desirable as I want to keep the singleton totally separate from the display aspect. This seems related to: http://stackoverflow.com/questions/1623396/refresh-cocoa-binding-nsarraycontroller-combobox The line: "editing the array behind the controller's back" seems to perhaps pinpoint the problem, but I would hope that it would be possible to have the singleton not know about the controller. Thanks in advance.

  • WPF 3D extrude "a bitmap"

    - by Bgnt44
    Hi, I'm looking for a way to simulate a projector in wpf 3D : i've these "in" parameters : beam shape : a black and white bitmap file beam size ( ex : 30 °) beam color beam intensity ( dimmer ) projector position (x,y,z) beam position (pan(x),tilt(y) relative to projector) First i was thinking of using light object but it seem that wpf can't do that So, now i think that i can make for each projector a polygon from my bitmap... First i need to convert the black and white bitmap to vector. Only Simple shape ( bubble, line,dot,cross ...) Is there any WPF way to do that ? Or maybe a external program file (freeware); then i need to build the polygon, with the shape of the converted bitmap , color , size , orientation in parameter. i don't know how can i defined the lenght of the beam , and if it can be infiny ... To show the beam result, i think of making a room ( floor , wall ...) and beam will end to these wall... i don't care of real light render ( dispersion ...) but the scene render has to be real time and at least 15 times / second (with probably from one to 100 projectors at the same time), information about position, angle,shape,color will be sent for each render... Well so, i need sample for that, i guess that all of these things could be useful for other people If you have sample code : Convert Bitmap to vector Extrude vectors from one point with a angle parameter until collision of a wall Set x,y position of the beam depend of the projector position Set Alpha intensity of the beam, color Maybe i'm totally wrong and WPF is not ready for that , so advise me about other way ( xna,d3D ) with sample of course ;-) Thanks you

  • Unable to import Eclipse project to Android studio

    - by Binoy Babu
    Whenever I try to import my Eclipse project to Android Studio I get the following error : You are using an old, unsupported version of Gradle. Please use version 1.8 or greater. Please point to a supported Gradle version in the project's Gradle settings or in the project's Gradle wrapper (if applicable.)

  • Bind a SL4 TreeView to an IGrouping using Caliburn

    - by illdev
    I am just starting in the SL world and am trying to use the Caliburn NavigationShell as my starting point. I converted the solution to SL4 and use Caliburn from the trunk . To create the basic navigation, I am a bit unsure (well, quite), how I can display the original StackPanel of Buttons as a collapsible Treeview. I changed ITaskBarItem to own a simple GroupName property public interface ITaskBarItem : IEntryPoint { BitmapImage Icon { get; } string DisplayName { get; } string GroupName { get;} } then, I expose this in ShellViewModel to the View: public IEnumerable<IGrouping<string, ITaskBarItem>> TaskBarItems { get { return _taskBarItems.GroupBy(t => t.GroupName); } } How can I do the xaml markup so that I get a simple hierarchy? How can I bind Actions with out the use of Buttons? GroupName DisplayName DisplayName DisplayName GroupName DisplayName DisplayName DisplayName ... Mind, this is MVVM, so I am not going to use code behind or events to do that...

  • Mutability design patterns in Objective C and C++

    - by Mac
    Having recently done some development for iPhone, I've come to notice an interesting design pattern used a lot in the iPhone SDK, regarding object mutability. It seems the typical approach there is to define an immutable class NSFoo, and then derive from it a mutable descendant NSMutableFoo. Generally, the NSFoo class defines data members, getters and read-only operations, and the derived NSMutableFoo adds on setters and mutating operations. Being more familiar with C++, I couldn't help but notice that this seems to be a complete opposite to what I'd do when writing the same code in C++. While you certainly could take that approach, it seems to me that a more concise approach is to create a single Foo class, mark getters and read-only operations as const functions, and also implement the mutable operations and setters in the same class. You would then end up with a mutable class, but the types Foo const*, Foo const& etc all are effectively the immutable equivalent. I guess my question is, does my take on the situation make sense? I understand why Objective-C does things differently, but are there any advantages to the two-class approach in C++ that I've missed? Or am I missing the point entirely? Not an overly serious question - more for my own curiosity than anything else.

  • How to open a help webpage after installation is complete

    - by Kapil
    I have built an installer for my windows app using the VisualStudio 2008 IDE. I also use some custom-actions to do a few extra stuff at the time of installation/uninstallation. What I also want to do is that when the installation is completed, the installer should launch a help webpage or a getting-started page for the users to know how to go ahead with the app. I am doing the following for this: private void CustomInstaller_Committed(object sender, InstallEventArgs e) { System.Windows.Forms.LinkLabel lbl = new System.Windows.Forms.LinkLabel(); lbl.Links.Remove(lbl.Links[0]); lbl.Links.Add(0, lbl.Text.Length, "http://www.mywebsite.com/help.aspx"); ProcessStartInfo pInfo = new ProcessStartInfo(lbl.Links[0].LinkData.ToString()); Process.Start(pInfo); } Also, I set the event handler as such: this.Committed += new InstallEventHandler(CustomInstaller_Committed); This is launching the webpage, but not at the right point in the flow where I would have wanted it. It launches the IE browser even before the user dismisses the installation window (i.e clicks 'Close' in the Installation Completed dialog box). I want the webpage to open only when the user finally dismisses the installation. Any ideas how can I achieve this? Thanks, Kapil

  • Debugger Visualizer, ElementHost, and Edit and Continue problems

    - by Frank Fella
    I recently wrote a custom Debugger Visualizer for Visual Studio 2008 for one of the custom types in my application. The UI for the visualizer is written in WPF and is hosted in an element host and shown using the IDialogVisualizerService windowService object. Everything works great, and my visualizer loads and shows the relevant information, but if try to "edit and continue" in my application after loading the visualizer, Visual Studio crashes with no useful error message. In trying to debug this I removed almost all of my code from the solution to the point where I was only serializing a string with the ObjectSource and displaying just an empty element host and I still get the crash on edit and continue. If I remove the element host and show a WinForms control or form there is no crash. Here is the Visualizer code: using System; using System.Drawing; using System.IO; using System.Runtime.Serialization.Formatters.Binary; using System.Windows.Forms; using System.Windows.Forms.Integration; using Microsoft.VisualStudio.DebuggerVisualizers; using ObjectVisualizerShared; using ObjectVisualizerUI; namespace ObjectVisualizer { public class Visualizer : DialogDebuggerVisualizer { protected override void Show(IDialogVisualizerService windowService, IVisualizerObjectProvider objectProvider) { try { Stream stream = objectProvider.GetData(); if (stream.Length > 0) { BinaryFormatter formatter = new BinaryFormatter(); VisualizerNode node = (VisualizerNode)formatter.Deserialize(stream); if (node != null) { VisualizerWindow window = new VisualizerWindow(node); ElementHost host = new ElementHost(); host.Child = window; host.Dock = DockStyle.Fill; host.Size = new Size(800, 600); windowService.ShowDialog(host); } } } catch (Exception ex) { MessageBox.Show(string.Format("Error!\n{0}", ex), "Object Visualizer"); } } } } Any ideas?

  • How do I code Citrix web sites to use a Secure Gateway (CSG)?

    - by RAVolt
    I'm using Citrix's sample code as a base and trying to get it to generate ICA files that direct the client to use their Secure Gateway (CSG) provider. My configuration is that the ICA file's server address is replaced with a CSG ticket and traffic is forced to go to the CSG. The challenge is that both the Citrix App Server (that's providing the ICA session on 1494) and the CSG have to coordinate through a Secure Ticket Authority (STA). That means that my code needs to talk to the STA as it creates the ICA file because STA holds a ticket that the CSG needs embedded into the ICA file. Confusing? Sure! But it's much more secure. The pre-CSG code looks like this: AppLaunchInfo launchInfo = (AppLaunchInfo)userContext.launchApp(appID, new AppLaunchParams(ClientType.ICA_30)); ICAFile icaFile = userContext.convertToICAFile(launchInfo, null, null); I tried to the SSLEnabled information to the ICA generation, but it was not enough. here's that code: launchInfo.setSSLEnabled(true); launchInfo.setSSLAddress(new ServiceAddress("CSG URL", 443)); Now, it looks like I need to register the STA when I configure my farm: ConnectionRoutingPolicy policy = config.getDMZRoutingPolicy(); policy.getRules().clear(); //Set the Secure Ticketing Authorities (STAs). STAGroup STAgr = new STAGroup(); STAgr.addSTAURL(@"http://CitrixAppServerURL/scripts/ctxsta.dll"); //creat Secure Gateway conenction SGConnectionRoute SGRoute = new SGConnectionRoute(@"https://CSGURL"); SGRoute.setUseSessionReliability(false); SGRoute.setGatewayPort(80); SGRoute.setTicketAuthorities(STAgr); // add the SGRoute to the policy policy.setDefault(SGRoute); This is based on code I found on the Citrix Forums; however, it breaks my ability to connect with the Farm and get my application list! Can someone point me to an example of code that works? Or a reference document?

  • ClickOnce Deployment Error - Access to the Path is Denied

    - by michael.lukatchik
    I have a WPF app that I'm deploying to a network path using ClickOnce deployment. After the app is deployed to a network location, I use the ClickOnce html page to launch the installation process. I am successfully able to download and install the app. However, my users are not able to download and install the app. When a user navigates to the ClickOnce html page and clicks to begin the installation process, the following error message is received: ERROR SUMMARY Below is a summary of the errors, details of these errors are listed later in the log. * Activation of http://software.mycompany.com/myapp/myapp.application resulted in exception. Following failure messages were detected: + Downloading file://dev/webs/software/myapp/myapp.application did not succeed. * [4/5/2010 1:56:59 PM] System.Deployment.Application.DeploymentDownloadException (Unknown subtype) - Downloading file://dev/Webs/software/myapp/myapp.application did not succeed. All signs point to this being a security issue. So, I've done the following: Ensured that "Everyone" had read access to the files that were being deployed as part of my project Ensured that "Everyone" had read access to the network location where the app was deployed (//dev/webs/software/myapp) Ensured that "Everyone" had read access to the IIS path where the ClickOnce html page is located In each of these cases, I've made no progress in getting the app to successfully deploy via ClickOnce. Again, the odd thing is that I am able to successfully walk through the process of downloading and installing the app. It's my users, though, that need the ability to download and install the app. I've looked extensively on the web for answers, but there hasn't been much. I'd like to resolve the issue without "re-installing" or "rigging" anything. I need a solid answer. Thank you all for your input!! Mike

  • no statement parsed and wrong number or types of arguments - cfstoredproc

    - by Travis
    I have an Oracle procedure - editBacklog which I'm calling from a CFM page via cfstoredproc. After several changes to the procedure I started getting ORA-06550: line 1, column 7: PLS-00306: wrong number or types of arguments in call to 'EDITBACKLOG'. I've gotten this before and found that if I changed the name of the procedure it starts working again. I changed the name to editBacklog2 and it worked as I expected it to. I changed the name back to editBacklog and got the same error. I changed the name back to editBacklog2 again and started getting ORA-01003: no statement parsed. NOTHING has changed at this point except for the names. I changed the name yet again to editBacklog3 and it works as expected. As of right now editBacklog = ORA-06550 editBacklog2 = ORA-01003 editBacklog3 = works (kinda) This whole thing started when I was trying to fix an ORA-01821: date format not recognized error. I fear when I start changing things I'll start getting the same lame behavior described above. Either Oracle or CF is messing with me and I'll end up liking one of them less because of it. I assume it's probably cfstoredproc caching metadata or something but neither google, livedocs, or OTN have much to say about my situation. I'm not the SA or DBA. Anyone have any ideas?

  • Scalaz: request for use case

    - by oxbow_lakes
    This question isn't meant as flame-bait! As it might be apparent, I've been looking at Scalaz recently. I'm trying to understand why I need some of the functionality that the library provides. Here's something: import scalaz._ import Scalaz._ type NEL[A] = NonEmptyList[A] val NEL = NonEmptyList I put some println statements in my functions to see what was going on (aside: what would I have done if I was trying to avoid side effects like that?). My functions are: val f: NEL[Int] => String = (l: NEL[Int]) => {println("f: " + l); l.toString |+| "X" } val g: NEL[String] => BigInt = (l: NEL[String]) => {println("g: " + l); BigInt(l.map(_.length).sum) } Then I combine them via a cokleisli and pass in a NEL[Int] val k = cokleisli(f) =>= cokleisli(g) println("RES: " + k( NEL(1, 2, 3) )) What does this print? f: NonEmptyList(1, 2, 3) f: NonEmptyList(2, 3) f: NonEmptyList(3) g: NonEmptyList(NonEmptyList(1, 2, 3)X, NonEmptyList(2, 3)X, NonEmptyList(3)X) RES: 57 The RES value is the character count of the (String) elements in the final NEL. Two things occur to me: How could I have known that my NEL was going to be reduced in this manner from the method signatures involved? (I wasn't expecting the result at all) What is the point of this? Can a reasonably simple and easy-to-follow use case be distilled for me? This question is a thinly-veiled plea for some lovely person like retronym to explain how this powerful library actually works.

  • What's the proper way to setup different objects as delegates using Interface Builder?

    - by eagle
    Let's say I create a new project. I now add two text fields to the view controller in Interface Builder. I want to respond to delegate events that the text fields create, however, I don't want to have the main view controller to act as the delegate for both text fields. Ideally I want a separate file for each text field that acts as the delegate. Each of these objects also needs to be able to interact with the main view controller. My question is how I would set this up and link everything correctly? I tried creating a new class that inherits from NSObject and implements UITextFieldDelegate. I then added an instance variable called "viewController" of the same type of my view controller and marked it with IBOutlet (this required me to add #import "myViewcontroller.h"). I then went to Interface Builder and opened up my view controller which contains the two edit boxes. I added an NSObject to the form and changed it's type to be of the new class I created. I set its viewController property to the File's Owner, and set one of the textbox's delegate properties to point to this new object I created. Now when I run the program, it crashes when I touch the text box. It gives the error EXC_BAD_ACCESS. I'm guessing I didn't link stuff correctly in IB. Some things I'm not sure about which might be the problem: Does IB automatically know to create an instance of the class just by placing the NSObject in the ViewController? Can it properly assign the viewController property to an instance of itself even though it is creating itself at the same time?

  • Genetic Algorithms applied to Curve Fitting

    - by devoured elysium
    Let's imagine I have an unknown function that I want to approximate via Genetic Algorithms. For this case, I'll assume it is y = 2x. I'd have a DNA composed of 5 elements, one y for each x, from x = 0 to x = 4, in which, after a lot of trials and computation and I'd arrive near something of the form: best_adn = [ 0, 2, 4, 6, 8 ] Keep in mind I don't know beforehand if it is a linear function, a polynomial or something way more ugly, Also, my goal is not to infer from the best_adn what is the type of function, I just want those points, so I can use them later. This was just an example problem. In my case, instead of having only 5 points in the DNA, I have something like 50 or 100. What is the best approach with GA to find the best set of points? Generating a population of 100, discard the worse 20% Recombine the remaining 80%? How? Cutting them at a random point and then putting together the first part of ADN of the father with the second part of ADN of the mother? Mutation, how should I define in this kind of problem mutation? Is it worth using Elitism? Any other simple idea worth using around? Thanks

  • EF4 Generate Database

    - by shaneseaton
    Hi, I am trying my hardest to find the simplest way to create a basic "model first" entity framework example. However I am struggling with the actually generation of the database, particularly the running of the SQL against the database. Tools Visual Studio 2010 SQL Server 2008 Express Process Create a new class project Add a new Server-Database item (mdf) named "Database1.mdf" to the project Add an empty ADO.net Entity Model Create a simple entity (Person: Id, Name) Generate the Script selecting the Database1 connection created for me by visual studio Right click the script editor and select the "Execute SQL..." option Log in to SQLEXPRESS This is where is falls over saying it cant find a database name "Database1". The "problem" is that the SQL server has not had Database1 attached to it. I am 100% positive that Visual Studio use to attach a database to SQLExpress when it created a new database (Step 2). This appears to not be the case any more (even the beta of VS2010 did it). Can someone confirm this? or tell me how to get this to happen? Is there a way that I can modify the TSQL script to use an un-attached database. ie a file. I know I can use SQL Management Studio or sqlcmd to attach the database, but I would ideally like to avoid the solutions as I would like to see the cleanest method of just using visual studio. Ideal Solutions (in order of most prefered) Get visual studio to attach the newly created database Modify the generated SQL to point to file Thanks in advance.

  • NSIS takes ownership of IIS system files

    - by Lucas
    I recently encountered an issue with NSIS that I believe is related to an interaction with UAC, but I am at a loss to explain it and I do not know how to prevent it in the future. I have an installer that creates and removes IIS virtual directories using the NsisIIS plugin. The installer appeared worked correctly on my Windows 7 workstation. When the installer was run on a Windows 2008 R2 server it installed properly, but the uninstaller removed all of the virtual directories and put IIS is an unusable state; to the point that I had to remove the Default Web Site and re-add it. What I eventually found was that all of the IIS configuration files under C:\Windows\System32\inetsrv\config had a lock icon on them. Some investigation seem to indicate that this means a user account has taken ownership of the file, however all the files listed SYSTEM as the file owner. I did check a different server that I have not run the installer on, and it does not have the lock icon applied to the IIS files. I have also seen the same lock icon appear on other files that the NSIS installer creates. For instance, I have a Web.Config.tpl file that is processed using the NSIS ReplaceInFile which also appears with the lock icon after the installer finished. After I explicitly grant another user account access to the file, the lock icon goes away. I run the installer under the local Administrator account on the 2008 R2 server, so I do not get the UAC prompt. Here is the relevant code from the install.nsi file RequestExecutionLevel admin Section "Application" APP_SECTION SectionIn RO Call InstallApp SectionEnd Section "un.Uninstaller Section" Delete "$PROGRAMFILES\${PROGRAMFILESDIR}\Uninstall.exe" Call un.InstallApp SectionEnd Function InstallApp File /oname=Web.Config Web.Config.tpl !insertmacro ReplaceInFile Web.Config %CONNECTION_STRING% $CONNECTION_STRING FunctionEnd Function un.InstallApp ReadRegStr $0 HKLM "Software\${REGKEY}" "VirtualDir" NsisIIS::DeleteVDir "$0" Pop $0 FunctionEnd I have three questions stemming from this incident: How did this happen? How can I fix my installer to prevent it from happening again? How can I repair the permissions on the IIS config files.
