• SSRS and cached reports

  - by Tabloo Quijico

  Hi, I'm opening an SSRS2008 report using the http://server/reportserver/... syntax, outputting directly a PDF copy. This report has several parameters. The problem is that, despite making changes to the report, and clearing the browser's temporary files cache.. if I request the same report (i.e. same parameters) - the old report is returned. In the report execution properties, I have "Always run this report with the most recent data" and "Do not cache temporary copies of this report" selected. It's not just a case of caching data, but the entire report (including formatting, e.g. I deleted a page from the report yet it was still being shown...) and as I haven't specifically chosen to perform any caching I'm a little concerned and clearly don't fully understand what's going on! Any tips?

• C++ Boost ASIO: how to read/write with a timeout?

  - by Stéphane

  From reading other Stackoverflow entries and the boost::asio documentation, I've confirmed that there is no synchronous asio read/write calls that also provide an easy-to-use timeout as a parameter to the call. I'm in the middle of converting an old-school linux socket app with select(2) calls that employs timeouts, and I need to do more-or-less the same. So what is the best way to do this in boost::asio? Looking at the asio documentation, there are many confusing examples of various things to do with timers, but I'm quite confused. I'd love to see a simple-to-read example of this: Read from a socket, but wait for a maximum of X seconds after which the function either returns with nothing, or returns with whatever it was able to read from the socket before the timeout expired.

• Vim plugin Align fails to work. Can it be installed without vimball?

  - by Leonard

  I've happily installed the vim Align plugin on my home computer, but on the Red Hat servers at work, the installation doesn't work. The servers at work have a very old copy (2006) of vimball, which from Googling I know doesn't support more recent vimballs, including Align. I can't get the systems group (IT department) to upgrade vimball, so I thought perhaps I could simply copy the various files into ~/.vim/plugin by hand. I copied the 3 files from my home system AlignMapsPlugin.vim AlignPlugin.vim cecutil.vim, but when I attempt to use Align from within vim I get the following error message E117: Unknown function: Align#Align I know that it's seeing the plugin, because when I remove the plugin the error message is different (it says "Not an editor command Align"). Is there a workaround for this? I love "Align" and would sure like to use it at work as well as at home.

• MySQL UpdateXML with automatic node inserting?

  - by JimPsr

  I am writing an application that supports custom fields. Currently I store all custom fields in a XML formated text field ( e.g. '<root><field1>val1</field1><field2>val2</field2></root>' in cust_field) I am able to to use updateXML(cust_field, '/root/field1', '<field1>new value</field1') to update those values, however if I use updateXML(cust_field, '/root/field3', '<field3>new value</field3>') then it does not work since field3 is not in the old value. Is there a way to let MySQL automatically insert the new field3 node and its value into cust_field? I am thinking about stored procedure or even stored function but not familiar with both, can anyone point me to the right direction?

• Hibernate entities stored as HttpSession attribute values

  - by njudge

  I'm dealing with a legacy Java application with a large, fairly messy codebase. There's a fairly standard 'User' object that gets stored in the HttpSession between requests, so the servlets do stuff like this at the top: HttpSession session = request.getSession(true); User user = (User)session.getAttribute("User"); The old user authentication layer (which I won't describe; suffice to say, it did not use a database) is being replaced with code mapped to the DB with Hibernate. So 'User' is now a Hibernate entity. My understanding of Hibernate object life cycles is a little fuzzy, but it seems like storing 'User' in the HttpSession now becomes a problem, because it will be retrieved in a different transaction during the next request. What is the right thing to be doing here? Can I just use the Hibernate Session object's update() method to reattach the User instance the next time around? Do I need to?

• How do I get User.message_set messages to show up for the built in test client?

  - by Conley Owens

  I'm aware that the old Django messages framework is deprecated, but I still would like to know the answer to this. When I go to a certain url to my broswer, a message is created, I am redirected to a different page, and I see the message correctly displayed by my template. When the test client goes to the same url, the message is created, it gets a redirect, and after following the redirect there are no messages. However, no messages appear in the response (the response gotten from following the redirect). Why not?

• Sharepoint lockout

  - by user301751

  Recently a guy from our 3rd line team thought it would be funny to delete my account from AD. This has now been re-added. Everything is back to normal apart from my Access to Sharepoint sites. I am getting "The file exists. (Exception from HRESULT: 0x80070050)" Error on all sites. After some googleing I came across a guy with the same issue and it was an issue with the SID being different from my old account. Since this I deleted my account from Site Administrators and re-added. This would refresh the SID with the new one. I also check on the Content database that the site ID matched using the following transactions and the SIDs match. select s.Id, w.FullUrl from Sites s inner join Webs w on s.RootWebId = w.Id select * from UserInfo where tp_Login='domain\username' and tp_SiteID='' I am now a bit clueless.

• Tutorial on Consuming a WCF service in ASP.Net web site?

  - by Robert

  I'm attempting to create my first WCF service. I've created the service and now I'm trying to call it from a asp.net (vb) web site and I've tried adding a web reference to it and using the scvutil.exe to consume the service. So far neither have worked. It's not letting me declare the service in my code. If someone could point me to a good tutorial on how to consume a WCF service in an ASP.Net web site that would be great. I've found numorous on how to use them with AJAX or silverlight or windows apps but nothing on using it in just a plain old website.

• C++ DLLs newer version

  - by koumides

  All, I have a C++ COM DLL written using Visual Studio. All the interfaces have GUIDs in idl and rgs files. We want to create a new DLL with brand new GUIDs as we want it to co-exist on the same machine with the old one but with different logic. The number of GUIDs is more than 200. Is there a tool that finds the GUIDs and replaces them ? I noticed for every GUID in idl file there are 3 same ones in the rgs files. I am not really into C++ COM but I have to get this done : Rgds, MK

• Preloading images in HTML, is there a more modern way?

  - by John

  I have an image loaded by JS on a mouse event. It's a fairly big image so I want to make sure it gets pre-loaded. I reemmber some old techniques from years ago and found this example: <SCRIPT LANGUAGE = JAVASCRIPT> if (document.images) { img1 = new Image(); img2 = new Image(); img1.src = "imageName1.gif"; img2.src = "imageName2.gif" } </SCRIPT> I wondered if this is still good/relevant, or maybe browsers automatically detect unused images and preload them anyway? Note my page has to support IE6, so I might still need older techniques anyway, but I'm still interested if more modern browsers have a better way?

• Problems with system() calls in Linux

  - by Thomas

  I'm working on a init for an initramfs in C++ for Linux. This script is used to unlock the DM-Crypt w/ LUKS encrypted drive, and set the LVM drives to be available. Since I don't want to have to reimplement the functionality of cryptsetup and gpg I am using system calls to call the executables. Using a system call to call gpg works fine if I have the system fully brought up already (I already have a bash script based initramfs that works fine in bringing it up, and I use grub to edit the command line to bring it up using the old initramfs). However, in the initramfs it never even acts like it gets called. Even commands like system("echo BLAH"); fail. So, does anyone have any input?

• info about intel Cos embedded i86 os

  - by Tim Williscroft

  I've got some old Intel printer (Etherexpress XL ) print servers and they seem to be running an Intel OS called Cos aka Intel Client Os i86 I've found out that much just looking in the update files from Intel. It was at least partly written in C. How do I make a custom software image Intel Cos's boot loader will understand ? I know a host PC xmodem's the image to the client device, and I was wondering if anyone had already either reverse-engineered this or had original info ? or is my only recousre to reverse engineer the update file format ?

• x86 Assembly - printf doesn't print without "\n"

  - by Bitani

  So I'm confused. I'm going through the book "Programming from the Ground Up" and am working with using libraries. printf is working just fine so long as I include a "\n" in the string, but without it it will print absolutely nothing. Any idea why this happens? Code: .section .data my_str: .ascii "Jimmy Joe is %d years old!\n\0" my_num: .long 76 .section .text .globl _start _start: pushl my_num pushl $my_str call printf movl $1, %eax movl $0, %ebx int $0x80 Also, when I use -m elf_i386 for 32-bit mode and -dynamic-linker /lib/ld-linux.so.2 -lc to link, I get the warning ld: skipping incompatible /usr/lib64/libc.so when searching for -lc If that makes any difference, or if anybody has any suggestions as to how to have it load the 32-bit library directly. Thanks!

• Design guidelines for cache mechanism

  - by Delashmate

  Hi All, I got assignment to write design for cache mechanism (this is work assignment, not homework), This is my first time writing a design document, Our program display images for doctors, and we want to reduce the parsing time of the images So we want to save the parsed data in advance (in files or inside database) Currently I have several design key ideas: Handle locks - each shared data structure should be handled, also files Test - add test to verify the data from the cache is equal to the data from the files To decouple the connection to the database- not to call directly to the database Cleanup mechanisem- to delete old files if the cahce directory exceed configurable threshold Support config file Support performance tool in the feature I will also add class diagram, data flow charts, and workflow What do you think I should add to the key ideas? Do you know good link to atricales about design? Thanks in advance, Dan

• Hard drive randomly sppeeding up

  - by Glenn Taylor

  Having a weird issue with my hard drive. Running Windows 7 with an I5 processor. At random times the hard drive will start running at top speed and gradually return to normal over the next two minutes or so. Going to Resource Monitor it shows a variety of things with high read or write numbers. Log files NTFS volume log, Windows prefetch, System/user/appdata, and Program data Norton are the usual top ones listed. This just started about three months ago although the computer is about 3 years old. Have run in safe mode with internet over the weekend going to all of my usual sites with no such speed up. Question 1 - what can be causing this? Question 2 - how can I find out where data is being sent(especially if over the net)? Thank you.

• Is it possible to replace a div element with jquery and update the dom?

  - by Scarface

  Hey guys quick question, I want to update the contents of a div with two new divs to take the place of the previous ones. Each new div has a unique id to take the place of the old ones. I then want any further update to use the ids of the new divs as their values instead of the original. Is this possible in Jquery? Thanks in advance for any assistance. var display_total=$(".display_total").attr("id"); var display_of_total=$(".display_of_total").attr("id"); var new_display_of_total=parseInt(display_of_total)+1; var new_display_total=parseInt(display_total)+1; $('.totalmessages').html('<div class="display_of_total" id="'+new_display_of_total+'">Displaying '+new_display_of_total+' of </div><div class="display_total" id="'+new_display_total+'">'+new_display_total+' messages...</div>');

• form_for [@parent,@son],:remote=>true not asking for JS

  - by Cibernox

  Hi. I have a plain old form. That form is used to create new objects of a nested model. #restaurant.rb has_many :courses #courses.rb belongs_to :restaurant #routes.rb resources :restaurants do resources :courses end In my views(in haml), i have that code: %li.course{'data-random'=>random} = form_for([restaurant,course], :remote=>true) do |f| .name= f.text_field :name, :placeholder=>'Name here' .cat= f.hidden_field :category .price= f.text_field :price,:placeholder=>'Price here' .save = hidden_field_tag :random,random = f.submit "Save" I espected that form to be answered by action create of courses_controller with JS (create.js.erb), but it is submited like a normal form, and is answered with html. What am I doing wrong? This problem is similar to this but the only answer don't make sense to me. Thanks Inside

• Jquery/CSS help needed to make fallback for IE and older browsers

  - by matt_50

  Wondering if any of you can help me: I've made a signup modal that uses a CSS transform to switch between two methods of signing up. I've decided to try a 'card flip' type effect. Have a look at this JSfiddle in any browser that supports CSS 3D transforms - click the 'old fashioned way' text to 'flip' the modal (simplified for demo purposes): http://jsfiddle.net/voodoo6/cnTMz/8/ Then take a look in IE8/9 - as the 'back' is taller than the front and IE does;t support 'backface-visibility: hidden;' the reverse can be seen below the front. I've been trying to use JQuery and conditional CSS to 'display:none' the 'back' on load in IE (and older browsers), then add a 'display:block;' class to show it on click, problem is, I'm a JQuery beginner and have been struggling to get it to work! Not even sure if this is the best approach? Can anybody suggest an approach that would get this working in less-capable browsers? Thanks for any advice..

What could be best solution where I want the users to get either the old value or the new value of d and nothing in between.

• Port a Rails App from Windows to Mac or Linux

  - by Ryan Max

  Hello I've been a Rails developer on Windows for quite some time now, but I recently completed my biggest project yet (it's quite extensive, took me over a year to build) but I am having trouble deploying it. The combination of it's size, complexity and a windows environment is making it needlessly complex to deploy. I am thinking about getting an old mac mini and using it just for rails development. Either that or install unix on another box. Is there any way I can port my app to this mac or linux machine, without having to start over? I can't find any resources on the internets about this.

• using key/value collection in session

  - by jumpdart

  Question: What is a good datatype to keep in session for a large collection of keys and values to frequently reference and update? Application: Updating an old .NET web app with a million pages and grids to have all the grids maintain their sort. They currently access helper code to format themselves graphically on load and on sort. I figured I could add to that code to check for a key based on the page and grid id in a collection in session to see if it has a previous expression on load. and the on sort update/add its appropriate item in the collection. Thoughts? Dictionary vs NameValueCollection

• How to unload JVM from a living process?

  - by Guy

  Hi, I'm working with JNI and trying to unload (destroy) the VM using DestoryJavaVM function (I first call DetachCurrentThread method). It seems like the it has now influence on the VM and it is still up after the call. I read in old Sun posts that DestoryJavaVM had problems in the past (JDK1.1-1.3 in 2001) but I'm using JRE 6 and it probably should work now, right? I need to Load\Unload a VM in the same living process since each loading requires another classes to load. Any ideas how it can be done? Thanks, Guy
