  • Update to Alert on Java Runtime Environment (JRE) for EBS end-users on Windows

    - by user793553
    To ensure that Java users remain on a secure version, Windows systems that rely on auto-update will be auto-updated from JRE 6 to JRE 7. Until E-Business Suite is certified with JRE 7, EBS users should not rely on the Windows auto-update mechanism for their client machines and should manually keep the JRE up to date with the latest version of JRE 6 until further notice.   Click here for more details and for instructions on how to get the latest version of JRE 6

  • How do I change from locally generated File in Silverlight to a Website?

    - by Kris Erickson
    Because I want to do things like load images from the web, I guess I need to move my Silverlight project from using a default file to some kind of web package. I don't really want an ASP .Net site, in fact, I totally don't want an ASP.Net site and yet I want to be able to develop and load images from the web. How do I move my development files to a website and still be able to compile, debug, etc from Visual Studio?

  • ASP.Net: Is it possible to cache the js-proxies generated by scriptmanager?

    - by AndreasKnudsen
    We have the following code: <asp:ScriptManager runat="server"> ... <Services> <asp:ServiceReference Path="~/JSONServices/ProfileService.svc" /> </Services> ... This results in a Javascript proxy found in /JSONServices/ProfileService.svc/js. This Javascript has content expiry set to the same time it was called (so it is never cached on the client). Is it possible to have the clients cache these proxies for some time?

  • How do I save a file generated by an OS X Dashboard Widget?

    - by Weston C
    I've got a web app that I'm porting to an OS X Dashboard widget. The web app generates some data on the client side using JavaScript, and then, when the user wants to save it, sends it to a server-side script which relays the data back with the Content-disposition: attachment; HTTP header, triggering a save-file dialog in most browsers. I've tried duplicating this in the Dashboard environment. The Widget simply disappears. I don't know, but I suspect that it may be actually navigating to the unfamiliar content. So, how do I trigger a "save file dialog" -- or, failing that, use any method at all to save the data the Widget generates as a file?

  • Rand(); with exclusion to and already randomly generated number..?

    - by Stefan
    Hey, I have a function which calls a users associated users from a table. The function then uses the rand(); function to chose from the array 5 randomly selected userID's however!... In the case where a user doesnt have many associated users but above the min (if below the 5 it just returns the array as it is) then it gives bad results due to repeat rand numbers... How can overcome this or exclude a previously selected rand number from the next rand(); function call. Here is the section of code doing the work. Bare in mind this must be highly efficient as this script is used everywhere. $size = sizeof($users)-1; $nusers[0] = $users[rand(0,$size)]; $nusers[1] = $users[rand(0,$size)]; $nusers[2] = $users[rand(0,$size)]; $nusers[3] = $users[rand(0,$size)]; $nusers[4] = $users[rand(0,$size)]; return $nusers; Thanks in advance!

  • How to use the FindControl function to find a dynamically generated control?

    - by Abe Miessler
    I have a PlaceHolder control inside of a ListView that I am using to render controls from my code behind. The code below adds the controls: TextBox tb = new TextBox(); tb.Text = quest.Value; tb.ID = quest.ShortName.Replace(" ", ""); ((PlaceHolder)e.Item.FindControl("ph_QuestionInput")).Controls.Add(tb); I am using the following code to retrieve the values that have been entered into the TextBox: foreach (ListViewDataItem di in lv_Questions.Items) { int QuestionId = Convert.ToInt32(((HiddenField)di.FindControl("hf_QuestionId")).Value); Question quest = dc.Questions.Single(q => q.QuestionId == QuestionId); TextBox tb = ((TextBox)di.FindControl(quest.ShortName.Replace(" ",""))); //tb is always null! } But it never finds the control. I've looked at the source code for the page and the control i want has the id: ctl00_cphContentMiddle_lv_Questions_ctrl0_Numberofacres For some reason when I look at the controls in the ListViewDataItem it has the ClientID: ctl00_cphContentMiddle_lv_Questions_ctrl0_ctl00 Why would it be changing Numberofacres to ctl00? Is there any way to work around this? UPDATE: Just to clarify, I am databinding my ListView in the Page_Init event. I then create the controls in the ItemBound event for my ListView. But based on what @Womp and MSDN are saying the controls won't actually be created until after the Load event (which is after the Page_Init event) and therefore are not in ViewState? Does this sound correct? If so am I just SOL when it comes to retrieving the values in my dynamic controls from my OnClick event?

  • MS Excel automation without macros in the generated reports. Any thoughts?

    - by ezeki77
    Hello! I know that the web is full of questions like this one, but I still haven't been able to apply the answers I can find to my situation. I realize there is VBA, but I always disliked having the program/macro living inside the Excel file, with the resulting bloat, security warnings, etc. I'm thinking along the lines of a VBScript that works on a set of Excel files while leaving them macro-free. Now, I've been able to "paint the first column blue" for all files in a directory following this approach, but I need to do more complex operations (charts, pivot tables, etc.), which would be much harder (impossible?) with VBScript than with VBA. For this specific example knowing how to remove all macros from all files after processing would be enough, but all suggestions are welcome. Any good references? Any advice on how to best approach external batch processing of Excel files will be appreciated. Thanks! PS: I eagerly tried Mark Hammond's great PyWin32 package, but the lack of documentation and interpreter feedback discouraged me.

  • Xorg crashes ever since using Nvidia dual monitors

    - by legion
    Well ever since I have used dual monitors with the NVIDIA X Server Settings program my xorg process has been crashing after a while, and its generally a pretty long while of like 6 hours afterwards. Before NVIDIA changed my xorg.conf file I only had xorg crash like twice in 2 months, I can't figure out what is going on.

  • controlling the class names generated by JAXB for xsd:attributeGroup?

    - by Stephen Winnall
    I am using JAXB to bind XML to Java for an application that I am writing. I have an element called measure which contains two amount elements called amount and maxAmount, with which I want to model a lower and an upper limiting value. amount and maxAmount are otherwise identical and I would like them to be implemented with the same class when unmarshalled into Java. The following is an extract from the XML schema which I feed to JAXB: <xsd:attributeGroup name="AmountAttributes"> <xsd:attribute name="quantity" type="xsd:decimal"/> <xsd:attribute name="numerator" type="xsd:nonNegativeInteger"/> <xsd:attribute name="denominator" type="xsd:positiveInteger"/> </xsd:attributeGroup> <xsd:element name="measure"> <xsd:complexType> <xsd:sequence> <xsd:element minOccurs="0" name="amount"> <xsd:complexType> <xsd:attributeGroup ref="mpr:AmountAttributes"/> </xsd:complexType> </xsd:element> <xsd:element minOccurs="0" name="maxAmount"> <xsd:complexType> <xsd:attributeGroup ref="mpr:AmountAttributes"/> </xsd:complexType> </xsd:element> </xsd:sequence> </xsd:complexType> </xsd:element> JAXB creates from this a more elaborate version of the following: public class Measure { protected Measure.Amount amount; protected Measure.MaxAmount maxAmount; public static class Measure.Amount {} public static class Measure.MaxAmount {} } Measure.Amount and Measure.MaxAmount are identical except for their names, but - of course - as far as Java is concerned they have little to do with each other. Is there a way of making JAXB use the same class for both amount and maxAmount? Just to come completely clean ;-) I should mention that I generate the XML schema from RNC using Trang. If the answer to the question is "change the XML schema", I have the supplementary question "how do I change the RNC to produce that XML schema?". My RNC looks like this: AmountAttributes = QuantityAttribute? & attribute numerator { xsd:nonNegativeInteger }? & attribute denominator { xsd:positiveInteger }? QuantityAttribute = attribute quantity { xsd:decimal } Measure = element measure { element amount { AmountAttributes }?, element maxAmount { AmountAttributes }? }+ I use RNC because I find it simpler to understand, but if the solution to my problem means just using XML Schema, so be it.

  • How can I execute an insert with data from a repeater-generated form whose data source is SQL?

    - by Duke
    I'm storing multilingual data in a database whose model is language normalized (like this). For this particular problem the key for the table in question consists of a value entered by the user and a language from the language table. I'd like to dynamically generate a form with input fields for all available languages. The user inputs a key value then goes down a list of field sets filling out the information in each language. In this case there are two fields for every language, a name and a value (the value is language dependent.) I have all existing information displayed on the page with a gridview, below which I have a formview that is always in insert mode allowing the user to enter new data. Within the formview I have a repeater with an SQLDataSource that gets a list of available languages: <asp:Repeater ID="SessionLocaleRepeater" runat="server" DataSourceID="LocaleSQLDataSource" EnableViewState="false"> <ItemTemplate> <tr> <th scope="row"><%# DataBinder.Eval(Container.DataItem, "LocaleName") %></th> <td>Name:</td> <td><asp:TextBox ID="TextBox1" runat="server" Text="" /></td> <td>Number:</td> <td><asp:TextBox ID="TextBox2" runat="server" Text="" /></td> </tr> </ItemTemplate> </asp:Repeater> I figured that in order to insert this data I'd have to execute my sql server insert stored procedure for each item in the repeater; I am trying to use the formview inserting event. The problem is that the repeater isn't databound to the SQLDataSource until after the formview inserting event (inserting event is in PostBackEvent and databind is in PreRender), which means the controls and data are not available when the inserting event is fired. I tried databinding the repeater during the formview inserting event; the controls were available but the data was not. Would this have something to do with how/when the viewstate information is re-added to the controls? From what I've read, Viewstate is one of the first things to be restored. Given the order of events how can I get the data I need for the insert? I'm open to other solutions to creating dynamic input controls, but they will have to query the database to determine how many sets of controls to create.

  • Why column rename script generated by SSMS uses temporary name?

    - by abatishchev
    When I rename a table column in Designer mode in SQL Server Management Studio 2008 (both R2 and non-R2) and generate a change script it looks like this: EXECUTE sp_rename N'table.column', N'Tmp_columnNew', 'COLUMN' GO EXECUTE sp_rename N'table.Tmp_columnNew', N'columnNew', 'COLUMN' GO What for temporary column name is used? Why don't rename at once?

  • Emacs stops taking input when a file has changed on disk [migrated]

    - by recf
    I'm using Emacs v24.3.1 on Windows 8. I had a file change on disk while I had an Emacs buffer open with that file. As soon as I attempt to make a change to the buffer, a message appears in the minibuffer. Fileblah.txt changed on disk; really edit the buffer? (y, n, r or C-h) I would expect to be able to hit r to have it reload the disk version of the file, but nothing happens. Emacs completely stops responding to input. None of the listed keys work, nor do any other keys as far as I can tell. I can't C-g out of the minibuffer. Alt-F4 doesn't work, not does Close window from the task bar. I have to kill the process from task manager. Anyone have any idea what I'm doing wrong here? In cases it's various modes not playing nice with each other, for reference, my init.el is here. Nothing complex. Here's the breakdown: better-defaults (ido-mode, remove menu-bar, uniquify buffer `forward, saveplace) recentf-mode custom frame title visual-line-mode require final newline and delete trailing whitespace on save Markdown mode with auto-mode-alist Flyspell with Aspell backend Powershell mode with auto-mode-alist Ruby auto-mode-alist Puppet mode with auto-mode-alist Feature (Gherkin) mode with auto-mode-alist The specific file was a markdown file with Github-flavored Markdown mode and Flyspell mode enabled.

  • Why is an anonymous inner class containing nothing generated from this code?

    - by Andrew Westberg
    When run through javac on the cmd line Sun JVM 1.6.0_20, this code produces 6 .class files OuterClass.class OuterClass$1.class OuterClass$InnerClass.class OuterClass$InnerClass2.class OuterClass$InnerClass$InnerInnerClass.class OuterClass$PrivateInnerClass.class When run through JDT in eclipse, it produces only 5 classes. OuterClass.class OuterClass$1.class OuterClass$InnerClass.class OuterClass$InnerClass2.class OuterClass$InnerClass$InnerInnerClass.class OuterClass$PrivateInnerClass.class When decompiled, OuterClass$1.class contains nothing. Where is this extra class coming from and why is it created? package com.test; public class OuterClass { public class InnerClass { public class InnerInnerClass { } } public class InnerClass2 { } //this class should not exist in OuterClass after dummifying private class PrivateInnerClass { private String getString() { return "hello PrivateInnerClass"; } } public String getStringFromPrivateInner() { return new PrivateInnerClass().getString(); } }

  • Do I need to Salt and Hash a randomly generated token?

    - by wag2639
    I'm using Adam Griffiths's Authentication Library for CodeIgniter and I'm tweaking the usermodel. I came across a generate function that he uses to generate tokens. His preferred approach is to reference a value from random.org but I considered that superfluous. I'm using his fall back approach of randomly generating a 20 character long string: $length = 20; $characters = '0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ'; $token = ''; for ($i = 0; $i < $length; $i++) { $token .= $characters[mt_rand(0, strlen($characters)-1)]; } He then hashes this token using a salt (I'm combing code from different functions) sha1($this->CI->config->item('encryption_key').$str); I was wondering if theres any reason to to run the token through the salted hash? I've read that simply randomly generating strings was a naive way of making random passwords but is the sh1 hash and salt necessary? Note: I got my encryption_key from https://www.grc.com/passwords.htm (63 random alpha-numeric)

  • Analysing objects generated by a Java application in between GCs.

    - by elec
    Is there a tool which could be used to analyse the objects being created between two separate garbage collection run (= number of objects created and their type) ? Heapdumps dont really work here as they perform a GC when they're invoked (or at least that's what I observed everytime so far), and I want to see which objects are collected by the GC, not which objects are left after the GC run, if that makes sense. ...or is it possible somehow to inspect the nature and size of objects being collected by the garbage collector ?

  • How do I post back information from a webpage that has post-generated content?

    - by meanbunny
    Ok so I am very new to html and the web. Right now I am trying to generate list items on the fly and then have them post back to the web server so I know what the person is trying to obtain. Here is the code for generating the list items: foreach (var item in dataList) { MyDataList.InnerHtml += "<li><a runat='server' onclick='li_Click' id='" + item.Name + "-button'></a></li>"; } Further down I have my click event. protected void li_Click(object sender, EventArgs e) { //How do I determine here which item was actually clicked? } My question is how do I determine which list item was clicked? Btw, the code running behind is C#. EDIT 1 LinkButton link = new LinkButton(); link.ID = "all-button"; link.Text = "All"; link.Click += new EventHandler(link_Click); MyDataList.Controls.Add(link); Then below I have my link_Click event that never seems to hit a breakpoint. void link_Click(object sender, EventArgs e) { if (sender != null) { if (sender.GetType() == typeof(LinkButton)) { LinkButton button = (LinkButton)sender; if (button.ID == "all-button") { } } } } I know this has to be possible I just cant figure out what I am missing. Edit 2 Ok ok I think I know what the problem is. I was trying to add a second list inside of another list. This was causing the whole thing to have problems. It is working now.
