  • Error ORA-01034: Oracle not available

    - by Mark Hardcastle
    I have an old Novell server which runs DocsOpen. I know very little about this system, basically we had a disk fault which halted the system. The server was rebooted and came up, I had to manually mount the DATA volume and then reboot again. All seems to be working but nobody can get in to DocsOpen, getting the error ORA-01034: Oracle not available.

  • How is the Windows 7 activation going to be?

    - by Donny V
    I really hated the Windows Vista activation system Microsoft had. I hope that Windows 7 is going to go back to the simple serial key like Windows XP. You couldn't even upgrade hardware without Windows Vista bitching. What is the activation system they're using for Windows 7?

  • Imagemagick - File Naming

    - by Josh Crowder
    I am using the convert command to convert a pdf to multiple pngs, I need the naming conventions to be slide-##.png at the moment they come out like slide-1.png but because there is 20+ slides when I loop through them to add them into the model the order comes up wrong, so it looks like slide-1.png slide-10.png slide-11.png and so on, how can I force convert to use double numbers like 01 02 03 and so forth or is there a better way to loop through them, this is the code I have at the moment def convert_keynote_to_slides system('convert -size 640x300 ' + keynote.queued_for_write[:original].path + ' ~/rails/arcticfox/public/system/keynotes/slides/'+File.basename( self.keynote_file_name )+'0%d.png') slide_basename = File.basename( self.keynote_file_name ) files = Dir.entries('/Users/joshcrowder/rails/arcticfox/public/system/keynotes/slides') for file in files #puts file if file.include?(slide_basename +'-') self.slides.build("slide" => "#{file}") if file.include?(slide_basename) end end

  • Stop a stopwatch

    - by James Morgan
    I have the following code in a JPanel class which is added to a another class (JFrame). What I'm trying to implement is some sort of a stopwatch program. startBtn.addActionListener(new startListener()); class startListener implements ActionListener { public void actionPerformed(ActionEvent e) { Timer time = new Timer(); time.scheduleAtFixedRate(new Stopwatch(), 1000, 1000); } } This is another class which basically the task. public class Stopwatch extends TimerTask { private final double start = System.currentTimeMillis(); public void run() { double curr = System.currentTimeMillis(); System.out.println((curr - start) / 1000); } } The timer works fine and this is definitely far from complete but I'm not sure how to code the stop button which should stop the timer. Any advice on this? BTW I'm using java.util.timer

  • Problems setting up an ASP.NET MVC site on IIS7 w/ Nhibernate

    - by Brandon
    When deploying my published website to the host (Its a shared hosting plan) I get this error: [NullReferenceException: Object reference not set to an instance of an object.] System.Web.PipelineStepManager.ResumeSteps(Exception error) +929 System.Web.HttpApplication.BeginProcessRequestNotification(HttpContext context, AsyncCallback cb) +91 System.Web.HttpRuntime.ProcessRequestNotificationPrivate(IIS7WorkerRequest wr, HttpContext context) +508 I found this question which describes my problem, but I'm not initializing NHibernate in Application_Start, it is already being done in Init. The only other cause of this error I can find is that the Global.asax file is inheriting from a class other than HttpApplication, but I'm not doing that either. This is pretty much the Global.asax file protected void Application_Start() { AreaRegistration.RegisterAllAreas(); RegisterRoutes(RouteTable.Routes); } public override void Init() { base.Init(); if (_wasNHibernateInitialized) return; // Initialize NHibernate // Other setup like the StructureMap initialization } Is there any other reason why an ASP.NET MVC application would give this error when being deployed to IIS7?

  • Is there a literal notation for decimal in IronPython?

    - by jeroenh
    suppose I have the following IronPython script: def Calculate(input): return input * 1.21 When called from C# with a decimal, this function returns a double: var python = Python.CreateRuntime(); dynamic engine = python.UseFile("mypythonscript.py") decimal input = 100M; // input is of type Decimal // next line throws RuntimeBinderException: // "cannot implicitly convert double to decimal" decimal result = engine.Calculate(input); I seem to have two options: First, I could cast at the C# side: seems like a no-go as I might loose precision. decimal result = (decimal)engine.Calculate(input); Second option is to use System.Decimal in the python script: works, but pollutes the script, which should be understandable for my users... import clr import System def CalculateVAT(amount): return amount * System.Decimal(1.21) Is there a way to tell the DLR that the number 1.21 should be interpreted as a Decimal, much like I would use the '1.21M' notation in C#?

  • PHP - a different open_basedir per each virtual host

    - by Lopoc
    Hi I've came across on this problem, I have a sever running apache and php. We have many virtual hosts but we've noticed that a potentially malicious user could use his web space to browse other user's files(via a simple php script) and even system files, this could happens due to the php permissions. A way to avoid it is to set the open_basedir var in php.ini, yhis is very simple in a single host system, but in case of virtual hosts there would be a basebir per each host. Ho can I set dis basedir per each user/host? is there a way to let apache hereditate php privileges of the php file that has been requested E.G. /home/X_USER/index.php has as owner X_USER, when apache read the file index.php it checks its path and owner, simply I'm looking for a system set php basedir variable to that path. Thank in advance Lopoc

  • C#: Windows Forms: Getting keystrokes in a panel/picturebox?

    - by Rosarch
    I'm making a level editor for a game using windows forms. The form has several drop down menus, text boxes, etc, where the user can type information. I want to make commands like CTRL + V or CTRL + A available for working within the game world itself, not text manipulation. The game world is represented by a PictureBox contained in a Panel. This event handler isn't ever firing: private System.Windows.Forms.Panel canvas; // ... this.canvas = new System.Windows.Forms.Panel(); // ... this.canvas.PreviewKeyDown += new System.Windows.Forms.PreviewKeyDownEventHandler(this.canvas_PreviewKeyDown); What is the preferred way of doing this? Can a panel even receive keyboard input? I would like to allow the user to use copy/paste/select-all commands when working with the text input, but not when placing objects in the game world.

  • Why would Silverlight be crashing in Release but not in Debug mode?

    - by Edward Tanguay
    I have a Silverlight App that has worked well in Debug and Release modes for weeks. It still works well in Debug mode. However, now when I run it in Release mode, it starts, shows me the screen, loads the data, then hangs, and the browser (Firefox) closes automatically. I've tried other browsers and each of them crashes, Chrome says "The Silverlight Plug-In has crashed" for instance. Here are the last lines of Output that I get: 'firefox.exe' (Silverlight): Loaded 'System.Windows.Controls' 'firefox.exe' (Silverlight): Loaded 'System.Windows.Controls.Toolkit' 'firefox.exe' (Silverlight): Loaded 'C:\Program Files\Microsoft Silverlight\4.0.50524.0\en-US\mscorlib.debug.resources.dll' 'firefox.exe' (Silverlight): Loaded 'C:\Program Files\Microsoft Silverlight\4.0.50524.0\en-US\System.Windows.debug.resources.dll' The program '[1120] firefox.exe: Silverlight' has exited with code -2147023895 (0x800703e9). How can I get more information about what is happening at the point of crash in Release mode that is not happening in Debug mode?

  • YesNo MessageBox not closing when x-button clicked

    - by Simpzon
    When I open a MessageBox with options YesNo, the (usually) cancelling cross in the upper right is shown but has no effect. System.Windows.MessageBox.Show("Really, really?", "Are you sure?", MessageBoxButton.YesNo); If I offer YesNoCancel as options, clicking the cross closes the Dialog with DialogResult Cancel. System.Windows.MessageBox.Show("Really, really?", "Are you sure?", MessageBoxButton.YesNoCancel); I would have expected that the cross is "looking disabled" if not hidden at all, when clicking it has no effect. Probably I am not the first one observing this. What is your favorite way to hide/disable this button or workaround the issue? Note: I would prefer a solution that does not use System.Windows.Forms, since I am dealing with WPF projects and would like to avoid any InterOp if possible.

  • Session timeout issue

    - by Kumar
    I have a role based ASP.NET C# web application in which I am putting the menu object inside a session and I have a session timeout configured in the web.config as below: <forms defaultUrl="Home.aspx" loginUrl="Login.aspx" name=".ASPXFORMSAUTH" timeout="10"></forms> I first logged into the system as an employee and waited until the session expires and then when I click a link in the menu I am being rightly redirected to the login page with the ReturnUrl parameter. Now when I try to login to the system as an administrator I am still seeing the employee menu and not the admin menu. The method which loads the menu 1st checks to see if the menu session object is not null if so loads the menu from the session if not then it builds the menu and put it into session. So when the system timesout the menu session object is not being cleared. How can I fix this?

  • How can I setup a .NET Custom Action within WiX 3.0?

    - by Luke
    I need to setup a custom action within WiX 3.0. I have the following setup in my Windows application exe. I have viewed the question at StackOverflow: Removing files when uninstalling Wix however I can't get this working with WiX 3.0. This seems to deal with InstallUtilLib.dll, however I can't work out how I call the custom action within my main Windows app executable. Also, is there some method that I can use to manually invoke and test the OnBeforeUninstall function is working as expected? Imports System.Configuration.Install.Installer Imports System.IO Public Class CustomInstaller Inherits Configuration.Install.Installer Protected Overrides Sub OnBeforeUninstall(ByVal savedState As System.Collections.IDictionary) MyBase.OnBeforeUninstall(savedState) Try End Sub End Class

  • VB.NET WebBrowser control not navigating to a local document

    - by blerh
    I have this code set up to navigate to a certain .html document depending on what's selected from a ListBox: Private Sub FileList_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles FileList.SelectedIndexChanged HelpWindow.Navigate(System.AppDomain.CurrentDomain.BaseDirectory & "help\" & fileArray(FileList.SelectedIndex, 1)) End Sub The problem is, when I first select something in the ListBox, it successfully navigates to that file and displays it. But when I select something a second time it doesn't change. All of the paths it's trying to navigate to are correct. I've checked this 1000 times. Anyone have any clues why this isn't working? Thank you.

  • ASP.NET MVC F# controller action ignoring parameter

    - by Matt H
    Hi. I have a C# ASP.NET MVC project but my controllers are written in F#. For some reason, the following code doesn't work properly. namespace MvcApplication8.Controllers open System.Web.Mvc [<HandleError>] type ImageController() = inherit Controller() member x.Index (i : int) : ActionResult = x.Response.Write i x.View() :> ActionResult The parameter of the action is seemingly ignored. http://localhost:56631/Image/Index/1 = The parameters dictionary contains a null entry for parameter 'i' of non-nullable type 'System.Int32' for method 'System.Web.Mvc.ActionResult Index(Int32)' in 'MvcApplication8.Controllers.ImageController'. An optional parameter must be a reference type, a nullable type, or be declared as an optional parameter. Parameter name: parameters The controller otherwise works fine. I know that plenty of people have written F# mvc code, so, any ideas where I'm going wrong?

  • Problems with VBScript - RegRead when running as a service

    - by Brandon
    I am working on a script that runs under a custom installation utility, which is running as a service. To get the current user name the script executes this command: str_Acct_Name_Val = "HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\Logon User Name" str_Acct_Name = RegRead(str_Acct_Name_Val) When I run the script from the command prompt, it can read that value just fine (under an administrator account). When the value is attempted to be read with service/local system privileges, the read fails. What is the problem here? EDIT: Some additional information. When running as a service calling the current user name returns "SYSTEM" and my guess is that HKCU doesn't "exist" under the view of the SYSTEM, since there is technically no current user. There is a user logged in at the time, but not in the scope of the running script. Maybe there is somewhere in HKLM I could find the currently logged on user?

  • Two-way databinding of a custom templated asp.net control

    - by Jason
    I hate long code snippets and I'm sorry about this one, but it turns out that this asp.net stuff can't get much shorter and it's so specific that I haven't been able to generalize it without a full code listing. I just want simple two-way, declarative, edit-only databinding to a single instance of an object. Not a list of objects of a type with a bunch of NotImplementedExceptions for Add, Delete, and Select, but just a single view-state persisted object. This is certainly something that can be done but I've struggled with an implementation for years. This newest, closest implementation was inspired by this article from 4-Guys-From-Rolla. Unfortunately, after implementing, I'm getting the following error and I don't know what I'm missing: System.InvalidOperationException: Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control. If I don't use Bind(), and only use Eval() functionality, it works. In that way, the error is especially confusing. Update: Actually, using Eval() does NOT work, but using <%# Container.SampleString %> works. However, Eval("SampleString") gives the same error. That leads me back to this article I found earlier but had discarded. Now I believe it might be related, though I haven't cracked it yet ... Here's the simplified codeset that still produces the error: using System.ComponentModel; namespace System.Web.UI.WebControls.Special { public class SampleFormData { public string SampleString = "Sample String Data"; public int SampleInt = -1; } [ToolboxItem(false)] public class SampleSpecificFormDataContainer : DataBoundControl, INamingContainer { SampleSpecificEntryForm entryForm; internal SampleSpecificEntryForm EntryForm { get { return entryForm; } } [Bindable(true), Category("Data")] public string SampleString { get { return entryForm.FormData.SampleString; } set { entryForm.FormData.SampleString = value; } } [Bindable(true), Category("Data")] public int SampleInt { get { return entryForm.FormData.SampleInt; } set { entryForm.FormData.SampleInt = value; } } internal SampleSpecificFormDataContainer(SampleSpecificEntryForm entryForm) { this.entryForm = entryForm; } } public class SampleSpecificEntryForm : WebControl, INamingContainer { #region Template private IBindableTemplate formTemplate = null; [Browsable(false), DefaultValue(null), TemplateContainer(typeof(SampleSpecificFormDataContainer), ComponentModel.BindingDirection.TwoWay), PersistenceMode(PersistenceMode.InnerProperty)] public virtual IBindableTemplate FormTemplate { get { return formTemplate; } set { formTemplate = value; } } #endregion #region Viewstate SampleFormData FormDataVS { get { return (ViewState["FormData"] as SampleFormData) ?? new SampleFormData(); } set { ViewState["FormData"] = value; SaveViewState(); } } #endregion public override ControlCollection Controls { get { EnsureChildControls(); return base.Controls; } } private SampleSpecificFormDataContainer formDataContainer = null; [Browsable(false), DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)] public SampleSpecificFormDataContainer FormDataContainer { get { EnsureChildControls(); return formDataContainer; } } [Bindable(true), Browsable(false)] public SampleFormData FormData { get { return FormDataVS; } set { FormDataVS = value; } } protected override void CreateChildControls() { if (!this.ChildControlsCreated) { Controls.Clear(); formDataContainer = new SampleSpecificFormDataContainer(this); Controls.Add(formDataContainer); FormTemplate.InstantiateIn(formDataContainer); this.ChildControlsCreated = true; } } public override void DataBind() { CreateChildControls(); base.DataBind(); } } } With an ASP.NET page the following: <%@ Page Title="Home Page" Language="C#" MasterPageFile="~/Site.master" AutoEventWireup="true" CodeBehind="Default2.aspx.cs" Inherits="EntryFormTest._Default2" EnableEventValidation="false" %> <%@ Register Assembly="EntryForm" Namespace="System.Web.UI.WebControls.Special" TagPrefix="cc1" %> <asp:Content ID="HeaderContent" runat="server" ContentPlaceHolderID="HeadContent"> </asp:Content> <asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent"> <h2> Welcome to ASP.NET! </h2> <cc1:SampleSpecificEntryForm ID="EntryForm1" runat="server"> <FormTemplate> <asp:TextBox ID="TextBox1" runat="server" Text='<%# Bind("SampleString") %>'></asp:TextBox><br /> <h3>(<%# Container.SampleString %>)</h3><br /> <asp:Button ID="Button1" runat="server" Text="Button" /> </FormTemplate> </cc1:SampleSpecificEntryForm> </asp:Content> Default2.aspx.cs using System; namespace EntryFormTest { public partial class _Default2 : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { EntryForm1.DataBind(); } } } Thanks for any help!

  • How long does it take to iterate through a long loop?

    - by Carl Rosenberger
    On a modern 64-Bit machine, how long do you think it takes to iterate through all the positive long numbers? Below is a code snippet in Java to demonstrate the idea. Without running the code yourself, how long do you think this code is going to run? How long will similar code run in other programming languages? public class LongLoop { public static void main(String[] args) { long startTime = System.currentTimeMillis(); for (long i = 0; i < Long.MAX_VALUE; i++) { // do nothing, just loop } long stopTime = System.currentTimeMillis(); long duration = stopTime - startTime; System.out.println("Time taken: " + duration + " milliseconds"); } }

  • Using RouteExistingFiles to block access to existing files even if no route exists

    - by Michael Stum
    In ASP.net MVC 2, I can use routes.RouteExistingFiles = true; to send all requests through the routing system, even if they exist on the file system. Usually, this ends up hitting the "{controller}/{action}/{id}" route and throws an exception as the controller cannot be found. I do not want to use that route though (I have only a few URLs and they are specifically mapped), yet I would still like to prevent access to the file system. Basically I want to Whitelist pages using IgnoreRoute. Is there a built-in way to do this? My current approach is to still have the "{controller}/{action}/{id}" route and generate a 404 when this is hit, but I'm just wondering if something is built-in already?

  • Eclipse does not recognize Classes of the jar

    - by Tom Brito
    I've included a new jar in my jre/lib/ext folder, and updated the Eclipse jre so the Eclipse see the new jar in the default JRE System Library. The trouble is that even showing the jar in the JRE System Library, the Eclipse does not see the Classes. And the worst: Eclipse see tha packages! It don't see only the classes! Here is a printscreen showing the jar withing the JRE System Library, and the Eclipse preview showing only the packages: http://picasaweb.google.com/brito.pro/Fail#5458323206632279634 Any idea how to solve this? :?

  • How to cause AggregateException with TPL?

    - by Sly
    I'm trying to recreate the conditions that will cause this exception: System.AggregateException: A Task's exception(s) were not observed either by Waiting on the Task or accessing its Exception property. As a result, the unobserved exception was rethrown by the finalizer thread.` I wrote this program thinking I'd cause the exception but it does not: using System; using System.Threading.Tasks; namespace SomeAsyncStuff { class Program { static void Main(string[] args) { Task.Factory.StartNew(() => { throw new NullReferenceException("ex"); }); GC.Collect(); Console.WriteLine("completed"); } } } In my real application, I use TPL and I did not code my exception handling right. As a result I get that exception. Now I'm trying to recreate the same conditions in a separate program to experiment with unobserved exceptions.
