• No sound after upgrading to Ubuntu 11.10 from win7

  - by Tilman

  just as a prefix to my question, i'd like to note that i'm just now entering the world of Linux (unless you count my android, but that's a very different experience...) i have two computers now that run Ubuntu 11.10, the first of which i've had very little problems with, aside from figuring out the basics. the second, from which i'm writing this question, has (up to this point) only had one problem.... no sound. i've read a couple questions similiar and found little help as the component catalog doesn't have my computer listed. (in fact i'm not suprised this is a pos i had my mom grab from her work before they officially closed the doors behind them) had perfect sound before hand, and no sound now. sudo lspci -v brings up 00:1b.0 Audio device: Intel Corporation N10/ICH 7 Family High Definition Audio Controller (rev 01) Subsystem: Intel Corporation Device d608 Flags: bus master, fast devsel, latency 0, IRQ 45 Memory at ff980000 (64-bit, non-prefetchable) [size=16K] Capabilities: [50] Power Management version 2 Capabilities: [60] MSI: Enable+ Count=1/1 Maskable- 64bit+ Capabilities: [70] Express Root Complex Integrated Endpoint, MSI 00 Capabilities: [100] Virtual Channel Capabilities: [130] Root Complex Link Kernel driver in use: HDA Intel Kernel modules: snd-hda-intel any help would be greatly appreciated, me and my gf just wanna watch a damn movie lol

• Thoughts on exception handling.

  - by AndyScott

  Was working on a windows form app (something I haven't done in a while), adding threading and logging so that it would work a little more smoothly and have a record of who did what.  I was just about at the point where I was going to check it into source control when I noticed that the Output window was showing "A first chance exception of type 'System.InvalidCastException' occurred in mscorlib.dll", so I googled it.  In reading some threads about the error, I came across the following comment and it got me thinking: "In addition, while they should be avoided if possible, exceptions are a quite legitimate part of program execution. It's their going unhandled that is a real issue, because that means crashy, crashy." How do you normally use exception handling?  I feel that exceptions are intended to handle errors in code (in my experience generally related to bad data making its way into the system).  Now don't get me wrong, I understand that exceptions happen and should be dealt with, but I feel that they are a "last resort" to keep a program from crashing, but should never be a way to pass data or continue logical processing that could be handled in standard code flow. I mention this, because I have seen it done. What do you think?

• I can't program because the code I am using uses old coding styles. Is this normal to programmers? [closed]

  - by Renato Dinhani Conceição

  I'm in my first real job as programmer, but I can't solve any problems because of the coding style used. The code here: Does not have comments Does not have functions (50, 100, 200, 300 or more lines executed in sequence) Uses a lot of if statements with a lot of paths Has variables that make no sense (eg.: cf_cfop, CF_Natop, lnom, r_procod) Uses an old language (Visual FoxPro 8 from 2002), but there are new releases from 2007. I feel like I have gone back to 1970. Is it normal for a programmer familiar with OOP, clean-code, design patterns, etc. to have trouble with coding in this old-fashion way? EDIT: All the answers are very good. For my (un)hope, appears that there are a lot of this kind of code bases around the world. A point mentioned to all answers is refactor the code. Yeah, I really like to do it. In my personal project, I always do this, but... I can't refactor the code. Programmers are only allowed to change the files in the task that they are designed for. Every change in old code must be keep commented in the code (even with Subversion as version control), plus meta informations (date, programmer, task) related to that change (this became a mess, there are code with 3 used lines and 50 old lines commented). I'm thinking that is not only a code problem, but a management of software development problem.

• MDaemon vs Exchange (2007-2010). Which way should we choose ?

  - by Deniz

  We are at the verge of a mail server decision. We do currently use 2 mail servers : MDaemon 10 and Exchange 2003. We are planning to use a company and customer wide one point solution. Our main candidates are MDaemon 11 and Exchange 2007 or 2010. We would like to learn other users experiences on those solutions. The server-side experiences, the user-side experiences , TCO, support options etc. And if there where other solutions (maybe MDaemon 11 + Exchange or anything else) you could suggest ?

• What kind of eye wear can I use to protect my eyes from staring at a screen all day?

  - by dr dork

  Many of us stare at computer screens all day. Lately, my eyes have been irritated from prolonged staring at my computer screens. Does anyone use or know of any eye wear technology that helps with this? About five years back, I bought a pair of prescription-1 eye glasses that had a no-glare layer put on them. It slightly helped, so I'm considering getting another pair. Is this the best option I have at this point? Thanks so much in advance for your wisdom!

• Simple website with a GPL V3 Framework

  - by sineverba

  I write web-based software and simple website ("Home", "Who we are", "Contact"). For a simple website I'm using a covered GPL v3 framework. The user surf the website, send an email, take info, etc. I repeat: simple website, not a Joomla or Wordpress. 1) Will the website be covered with the GPL? I don't modify the framework. I'm using his classes in other classes... (OOP). 2) For the point 1, if yes, do I need to add (e.g. in the footer) name of framework and his link? 3) I must permit download of entire website to study code (nothing that a programmer has interest in)? E.g. placing it in Github? 4) If 2 is NO, how you can "understand" that we use that framework? In effect no php lines are exposed to the browser... You cannot understand that when you push "Send email" the site is calling $this->send($email). If you write me an email "Are you using XXX framework"? I can answer NO.

• Trouble with Collada bones

  - by KyleT

  I have a Collada file with a rigged mesh. I've read the node tags in the library_visual_scenes tag and extracted the matrix for each node and stored everything in a hierarchical bone structure. My Matrix container is "row major", so I'd store the first float of a matrix tag in the 1st row, 1st column, the second in the 1st row, 2nd column, etc. From what I gather this is the Bind Pose Matrix. After that I went through the tag and extracted the float array in the source tag of the skin tag of the controller for the mesh. I stored each matrix from this float array in their corresponding Bone as the Inverse Bind Matrix. I also extracted the bind-shape-matrix and stored it. Now I'd like to draw the skeleton with OpenGL to see if everything is working correctly before I go about skinning. I iterate once over my bones and multiply a bone's Bind Pose Matrix by it's parents and store that. After that I iterate again over the bones and multiply the result of the previous matrix multiplication by the Inverse Bind Matrix and then by the Bind Shape Matrix. The results look something like this: [0.2, 9.2, 5.8, 1.2 ] [4.6, -3.3, -0.2, -0.1 ] [-1.8, 0.2, -4.2, -3.9 ] [0, 0, 0, 1 ] I've had to go to various sources to get the little understanding of Collada I have and books about 3d transform matricies can get pretty intense. I've hit a brick wall and if you could please read through this and see if there is something I'm doing wrong, and how I'd go about getting an X,Y,Z to draw a point for each of these joints once I've calculated the final transform, I'd really appreciate it.

• How to stay creative when going through tough emotional times (divorce, family death, etc)? [closed]

  - by gaearon

  Hi everyone. I believe this is not a duplicate of motivation question because I want to especially emphasize the emotional breakdown. You may conquer lack of motivation by working harder and getting through the dip, however this was not the case when I was separating with my girlfriend. I actually liked the project, it was (and it still is!) my first programming job at an amazing workplace and I wasn't being pressured in any way but I found myself absolutely unable to code, blankly staring at the screen, my thoughts disorganized, the feeling of emptiness all in my chest. I could perform some straightforward coding but anything that involves creative thinking, designing abstractions, solving new problems and, worst of all, fixing bugs in legacy code, completely wiped out my brain to the point I started avoiding work, which I never have done before. Coffee only used to make it worse. Eventually I got over that, and I remember the happy day I solved a problem elegantly and thought—hell, first time in a month! Thankfully the project wasn't top priority and I had the time to catch up. I wonder now, was there any other way to boost my productivity back then? I bet people would say I should've taken a break—and I think I really should have—but what if I needed the money? Didn't want to lose my job? Are there any ways to trick your brain into being creative despite emotional losses? From your experience, would it be worth talking to my boss, collegues?

• Assigning a script to a keystroke to toggle touchpad

  - by sodiumnitrate

  Since my default sony vaio shortcuts don't completely work in Ubuntu 12.04, I'd like to assign a script to Fn + F1, which toggles the touchpad on and off, so that the cursor would stop moving while I'm typing. Since I use a mouse and rarely need to use the touchpad, I don't want to use "disable touchpad while writing", which doesn't really seem to work anyway. I figured that using a script with the following command (this works, but I have to open up a terminal each time): xinput set-prop 12 "Device Enabled" 0 I have two problems at this point. One is that I don't know how to write this script so that it will toggle it off if it is on, and on if it is off. I know I should use an if statement but I don't know what value I should be checking to see if it is on or off. The second one is that I am having problems creating a new shortcut. I use System Settings - Keyboard - Shortcuts. I tried to add, to custom shortcuts, a new one by clicking the '+' sign. I named it Toggle Touchpad, and added the path to the executable script with the line above, by typing /home/irem/.toggletouchpad I have made it an executable with chmod. The problem is that when I click apply, and then click back on it to define the keystroke, it re-opens the dialogue. I cannot define new keys. (It says disabled on the right column of the entry). I have also tried xbindkeys, which almost constantly crashes. I'd prefer the system settings, if I can set the shortcut. I'd appreciate if anyone can help. Thanks.

• RESTful applications logic and cross resource operations

  - by Gaz_Edge

  I have an RESTful api that allows my users to receive enquiries about their business e.g. 'I would like to book service x on date y. Is this available?'. The api saves this information as a resource to the following URI users/{userId}/enquiries/{enquiryId} The information shown when this resource is retrieved are the standard sort of things you'd expect from an enquiry - email, first_name, last_name, address, message The api also allows customers to be created for a user. The customer has a login and password and also a profile. The following URIs expose these two resources PUT users/{userId}/customers/{customerId} PUT users/{userId}/customers/{customerId}/profile The problem I am having is that I would like to have the ability to allow users to create a customer from an enquiry. For example, the user is able to offer their service on the date requested and will then want to setup a customer with login details etc to allow them to manage the rest of the process. The obvious answer would be to use a URI like users/{userId}/enquiries/{enquiryId}/convert-to-client The problem with this is is that it somewhat goes against a lot of what I've been reading about how to implement REST (specifically from the book Restful Web Services which suggests that URIs should point to resources not operations on resources). The other option would be to get the client application (i.e. the code that calls the api) to handle some of this application logic. This doesn't quite feel right to me. I have implemented in my design that the client app is fairly dumb. It knows just enough to display the results from the API, and does not contain any application logic. Would be great to hear what others views are on the best way of setting this up Am I wrong to have no application logic in the client app? How would I perform this operation purely in the REST api?

• Can I set a hyperlink's display text from a document property?

  - by themel

  I'm trying to make a word document customizable through a document property that contains the base URL of all the links. I've managed to make the links themselves reference the document property like this: { HYPERLINK { QUOTE "http://{ DOCPROPERTY Host}/some/path" } } Changing the document property and updating the files makes the hyperlinks point to the correct URL. However, visually, nothing changes - the old URL is still shown as the display text of the hyperlink. Is there a way to make this work? Microsoft docs helpfully state You can edit the display text for the field by typing over it. but I can't figure out how that is supposed to work - even if I manually type over the hyperlink, it includes the edits in the field code instead of adjusting the display text. Currently attempting in Word 2002, but 2010 also available.

• How can I instruct nautilus to pre-generate PDF thumbnails?

  - by Glutanimate

  I have a large library of PDF documents (papers, lectures, handouts) that I want to be able to quickly navigate through. For that I need thumbnails. At the same time however, I see that the ~/.thumbnails folder is piling up with thumbs I don't really need. Deleting thumbnail junk without removing the important thumbs is impossible. If I were to delete them, I'd have to go to each and every folder with important PDF documents and let the thumbnail cache regenerate. I would love to able to automate this process. Is there any way I can tell nautilus to pre-cache the thumbs for a set of given directories? Note: I did find a set of bash scripts that appear to do this for pictures and videos, but not for any other documents. Maybe someone more experienced with scripting might be able to adjust these for PDF documents or at least point me in the right direction on what I'd have to modify for this to work with PDF documents as well. Edit: Unfortunately neither of the answers provided below work. See my comments below for more information. Is there anyone who can solve this?

• Ubuntu doesn't start and I can't login [migrated]

  - by Meph00

  My ubuntu 13.04 doesn't boot anymore. Eternal black screen. If I press ALT+CTRL+F1 I see that it's stucked on "Checking battery state [OK]." I'd like to try to go with sudo apt-get install gdm but I can't login on terminal tty2, tty3 etc. They correctly ask for my nickname, then they make me wait a lot, ask for password and make me wait again. After a lot of time (... a lot) the best I could achieve was visualizing "Documentantion https://help.ubuntu.com". I can never reach the point where I can give commands. Plus, during the long pauses, every 2 minutes it gives a messagge like this: INFO: task XXX blocked for more than 120 seconds. Any suggestion? Sorry for my bad english and thanks everyone for the attention.

• Project Management Software / 1 maybe 2 developers

  - by Ominus

  I am looking for software that I can use to "manage" multiple projects (5 - 10). Here are the features I would like but any recommendation is welcome. Bug/Feature tracking on a per project basis. Some way to keep all documents, diagrams, specs, requirements, in one place with the project. Better yet a tool where all these things or most of them could be authored. Task management during the development phase with milestones and estimates/actuals. Git integration I have been doing contract work and i have been doing really well for myself as far as getting projects but its becoming VERY hard to manage everything in an efficient manner. I am trying to learn about best practices when it comes to software programming methodologies and the more I read the more i realize that I am just managing these projects poorly. I am getting things done but the more I take on the less "solid" everything is. I am afraid if I don't get some good solid tools/practices in place I am going to do my customers and myself a disservice. The problem is that there are SO many options that its hard to weed through them all. I was at a point today where I had decided that I would just code my own (there is some irony here)! Obviously everyone has their likes dislikes I would love to hear from some of you lone programmers and how you manage everything since our needs aren't exactly the same thing that a large team might need. I also want a solution that can scale to 2 maybe 3 developers if I end up hiring some people to help with my work load. Thanks again for your usual insights!

• Windows Server 2003: Remapping external domain

  - by Chuck Harmston

  We're playing a going-away prank on a coworker, and would like to use a rule in our internal DNS server to redirect techcrunch.com to point at one of our internal development servers. Basically, I'd like to accomplish the same thing as adding a line to a Linux /etc/hosts file, only for the entire network. I have access to our DNS server. How would you go about doing this? I created an entry in the reverse lookup subnet with the 'Host Name' of techcrunch.com and the 'Host IP' of our development server, a Linux box running Debian on which I've created a virtualhost to handle requests to techcrunch.com. It doesn't appear to be working, however, and my expertise has reached its limit. Thanks!

• Which linux x86 hardware keystore?

  - by byeo

  I'm terminating SSL/TLS in my DMZ and I have to assume that machine will be hacked. At which point my certificates are compromised. Previously I've used nCipher hardware keystore/accelerator to solve this issue. These cards won't reveal the private key even to root. The card performs the encryption and decryption onboard and is hardened against physical attack. The only way to get at the keys is by attaching a smart card reader to the card itself. I'm having trouble finding information about something to recreate this approach. Is this the domain of specialist switches and firewalls these days? This old page references some of the old hardware: http://www.kegel.com/ssl/hw.html#cards

• prevent use of 'net user' command to change passwords on windows vista / xp

  - by guest

  hello the point is, if i'm logged in (and as almost every windows user, i've got an admin-account), and someone comes across my not locked pc, it is possible to change my password the pro-way through using: net user Admin %NEW_PASSWD% what can i do to prevent that, besides not being logged in as admin. i once saw a way, where the 'net user' command was substituted by a .bat file. so if you call 'net user Admin ...', it runs this .bat-file instead, which locks the notebook immediately. problem is, i honestly don't know how i could let windows substitute eg net.exe with a .bat-file. (too little windows knowledge) do you know any way how to do it? i'd appreciate it.

• Clouds, Clouds, Clouds Everywhere, Not a Drop of Rain!

  - by sxkumar

  At the recently concluded Oracle OpenWorld 2012, the center of discussion was clearly Cloud. Over the five action packed days, I got to meet a large number of customers and most of them had serious interest in all things cloud.  Public Cloud - particularly the Oracle Cloud - clearly got a lot of attention and interest. I think the use cases and the value proposition for public cloud is pretty straight forward. However, when it comes to private cloud, there were some interesting revelations.  Well, I shouldn’t really call them revelations since they are pretty consistent with what I have heard from customers at other conferences as well as during 1:1 interactions. While the interest in enterprise private cloud remains to be very high, only a handful of enterprises have truly embarked on a journey to create what the purists would call true private cloud - with capabilities such as self-service and chargeback/show back. For a large majority, today's reality is simply consolidation and virtualization - and they are quite far off from creating an agile, self-service and transparent IT infrastructure which is what the enterprise cloud is all about.  Even a handful of those who have actually implemented a close-to-real enterprise private cloud have taken an infrastructure centric approach and are seeing only limited business upside. Quite a few were frank enough to admit that chargeback and self-service isn’t something that they see an immediate need for.  This is in quite contrast to the picture being painted by all those surveys out there that show a large number of enterprises having already implemented an enterprise private cloud.  On the face of it, this seems quite contrary to the observations outlined above. So what exactly is the reality? Well, the reality is that there is undoubtedly a huge amount of interest among enterprises about transforming their legacy IT environment - which is often seen as too rigid, too fragmented, and ultimately too expensive - to something more agile, transparent and business-focused. At the same time however, there is a great deal of confusion among CIOs and architects about how to get there. This isn't very surprising given all the buzz and hype surrounding cloud computing. Every IT vendor claims to have the most unique solution and there isn't a single IT product out there that does not have a cloud angle to it. Add to this the chatter on the blogosphere, it will get even a sane mind spinning.  Consequently, most  enterprises are still struggling to fully understand the concept and value of enterprise private cloud.  Even among those who have chosen to move forward relatively early, quite a few have made their decisions more based on vendor influence/preferences rather than what their businesses actually need.  Clearly, there is a disconnect between the promise of the enterprise private cloud and the current adoption trends.  So what is the way forward?  I certainly do not claim to have all the answers. But here is a perspective that many cloud practitioners have found useful and thus worth sharing. To take a step back, the fundamental premise of the enterprise private cloud is IT transformation. It is the quest to create a more agile, transparent and efficient IT infrastructure that is driven more by business needs rather than constrained by operational and procedural inefficiencies. It is the new way of delivering and consuming IT services - where the IT organizations operate more like enablers of  strategic services rather than just being the gatekeepers of IT resources. In an enterprise private cloud environment, IT organizations are expected to empower the end users via self-service access/control and provide the business stakeholders a transparent view of how the resources are being used, what’s the cost of delivering a given service, how well are the customers being served, etc.  But the most important thing to note here is the enterprise private cloud is not just an IT project, rather it is a business initiative to create an IT setup that is more aligned with the needs of today's dynamic and highly competitive business environment. Surprised? You shouldn’t be. Just remember how the business users have been at the forefront of public cloud adoption within enterprises and private cloud is no exception.   Such a broad-based transformation makes cloud more than a technology initiative. It requires people (organizational) and process changes as well, and these changes are as critical as is the choice of right tools and technology. In my next blog,  I will share how essential it is for enterprise cloud technology to go hand-in hand with process re-engineering and organization changes to unlock true value of  enterprise cloud. I am sharing a short video from my session "Managing your private Cloud" at Oracle OpenWorld 2012. More videos from this session will be posted at the recently introduced Zero to Cloud resource page. Many other experts of Oracle enterprise private cloud solution will join me on this blog "Zero to Cloud"  and share best practices , deployment tips and information on how to plan, build, deploy, monitor, manage , meter and optimize the enterprise private cloud. We look forward to your feedback, suggestions and having an engaging conversion with you on this blog.

• Host forwarding fails, server is up, domain name tests ambiguous

  - by jayunit100

  I have a domain name registered with http://www.registryrocket.com/ The "main" site, which is called rudolfcode.net, is registered under godaddy, and forwards to a heroku site (rudolfcode.herokuapp.com). I have found that the main site, rudolfcode.net works, but the hostgator forwarding has stopped working (firefox simply fails when you point to http://www.rudolflabs.com, which is the domain name registered by hostgator). How can I debug this issue ? Finally, I have tried to run some DNS tests, and here are the results : Im not sure what the failures mean .... But Im pretty sure that "Conecting to WWW Home Page" failed is a pretty bad sign ! Thanks.

• Dynamic quadrees

  - by paul424

  recently I come out writing Quadtree for creatures culling in Opendungeons game. Thing is those are moving points and bounding hierarchy will quickly get lost if the quadtree is not rebuild very often. I have several variants, first is to upgrade the leaf position , every time creature move is requested. ( note if I would need collision detection anyway, so this might be necessery anyway). Second would be making leafs enough large , that the creature would sure stay inside it's bounding box ( due to its speed limit). The partition of a plane in quadtree is always fixed ( modulo the hierarchical unions of some parts) . For creatures close to the center of the plane , there would be no way of keeping it but inside one big leaf, besides this brokes the invariant that each point can be put into any small area as desired. So on the second thought could I use several quadrees ? Each would have its "coordinate axis XY" somwhere shifted ? Before I start playing with this maybe some other space diving structure would suit me better, unfortunetly wiki does not compare it's execution time : http://en.wikipedia.org/wiki/Grid_%28spatial_index%29#See_also

• (Preferably) Encrypted Server Backups

  - by Shoaibi

  I have somehow managed to purchase a VPS after collecting money for sometime, now problem is i cant find a way to backup the server. My previous approach was: Got a webdav account from mydisk.se, mounted it on the vps, used duplicity and created encrypted backups. Problem is it was only 2G, and its running out of space, at my own place i dont have a stable internet connection else i have a 500G drive that i could surely use for backups. The vps has a 12G HD, and i would like to backup /home, /root, /etc, /var/ (specially log and www). Any ideas are welcomed. [EDIT] I am more of looking for resource of setting up a backup-point or such(i know how to setup a backup server, but i cant as i dont have stable connection or the money to buy another VPS/disk for backup) , i have already got the tools needed.

• Can't login to Unity 3d after enabling Xinerama for a short moment

  - by Amir Adar

  Today I connected a second monitor to my computer. I set it up using nVidia's control panel, and all was working quite well, so I figured it won't be a problem to try Xinerama, just to see the difference between that and twinview. After enabling Xinerama and restarting the X session, I saw that I was logged into a Unity 2d session. I thought it was a problem with Xinerama, so I switched back to twinview, but it still logged me into Unity 2d. I tried disconnecting the second monitor, no luck: still Unity 2d. I tried changing GPU drivers and installing drivers from a separate ppa, and still I was logged into Unity 2d. Up until this point, I didn't have any problem logging into Unity 3d. It only happened after I tried using Xinerama. I should note that I was doing all this while updates were going on in the background, so it could be something related to that, though I can't imagine what (I tried booting with another kernel, but no luck). So what exactly happened? Did changing the mode to Xinerama triggered some other changes that I'm not aware of? Did these updates cause a certain malfunction in the driver? Is it something else?

• Part 4: Development Standards or How to share

  - by volker.eckardt(at)oracle.com

  Although we usually introduce the custom development part in EBS projects as “a small piece only” and “we will avoid as best as possible”, the development effort can be enormous and should therefore be well addressed by project standards. Any additional solution or additional software tool or product shall influence the custom development rules (by adding, removing or replacing sections). It is very common in EBS projects to create a so called “MD.030 Development Standards” document and put everything what’s related to development conventions into it. This document gets approval and will be shared among all developers. Later, additional sections have to be added, and usually the development lead is responsible for doing this. However, sometimes used development techniques are not documented properly, and therefore the development solutions deviate from each other, or from the initially agreed standards. My advice would be the following: keep the MD.030 as a base document, and add a Wiki on top. The “Development Wiki” covers the following: Collect input from every developer without updating the MD.030 directly Collect additional topics that might need further specification Allow a discussion about such topics by reviewing/updating the wiki directly Add also decisions or open questions right into it. In one of my own projects we were using this “Developer Wiki” quite extensive, and my experience is very positive. We had different sections in it, good cross references, but also additional material like code templates, links to external web pages etc. By using this wiki, the development standards became “owned” by the right group of people, the developers. They recognized that information sharing can improve the overall development quality, but will also reduce the workload on individuals. Finally, the wiki was much more accurate and helpful for the daily development work than our initial MD.030, and we all decided to retire the document completely. Summary: Information sharing in the development area is very important! The usual “MD.030 Development Standards“ is a good starting point, but should be combined with a “Development Wiki”, allowing everyone to address and discuss necessary improvements. A well-structured Wiki can replace the document in some sections completely. Side Note: The corresponding task in Oracle OUM (Oracle Unified Method) is DS.050 ‘Determine Design and Build Standards’ Volker

• MVC 3: ActionLink VB.Net

  - by xamlnotes

  Theres not a ton of good samples out there on using MVC with VB, so I am going to post some things that I am doing on a project. Lets look at links. I am converting a asp classic app to mvc.  One page has an anchor tag which I modified to look like so to point to a controller action: <A style=color:red; HREF='Detail/" & currentItem.IdNumber & "'>" & currentItem.IdNumber & "</A> This resolves out to what looks like the right URL and in fact the detail action is fired. The actions signature looks like so: Function Detail(ByVal IdNumber As String) As ActionResult But, IdNumber would always be blank, it was never set to the id passed in the url.  Hmm. So, I tried the following by using the ActionLink method of the html helper: Html.ActionLink(currentLead.LeadNumber, "Detail", New With {.IdNumber = currentItem.IdNumber })  Viola! That worked fine and the Detail method parameter was set just like it should be. Very interesting.
