  • Visual C# 2010 express... displaying console output??

    - by ClarkeyBoy
    Hi, I am currently creating a customer application for a local company. I have a datagridview linked to the customers table, and I am trying to link it up so that updates, inserts and deletions are handled correctly. I am very new to c# so I am starting with the basics (like about 2 days ago I knew nothing - I know vb.net, Java and several other languages though..). Anywho from what I understand anything output through Debug.WriteLine should only appear when in debug mode (common sense really) but anything output through Concole.WriteLine should appear whether or not in debug mode. However I have checked the immediate and output windows and nothing is being output when in normal mode. Does anyone have any idea why this is?? Thanks in advance, Richard

  • Getting Classic ASP to work in .js files under IIS 7

    - by Abdullah Ahmed
    I am moving a clients classic asp webapp to a new IIS7 based server. The site contains some .js files which have javascript but also classic asp in <% % tags which contains a bunch of conditional statements designed to spit out pieces of javascript based on session state variables. Here's a brief example of what the file could be like.... var arrHOFFSET = -1; var arrLeft ="<"; var arrRight = ">"; <% If ((Session("dashInv") = "True") And ((Session("systemLevelStaff") = "4") Or (Session("systemLevelCompany") = "4"))) Then %> addMainItem("/MgmtTools/WelcomeInventory.asp?wherefrom=salesMan","",81,"center","","",0,0,"","","","",""); <% Else %> <% If (Session("dashInv") = "False") And ((Session("systemLevelStaff") = "4") Or (Session("systemLevelCompany") = "4")) Then %> <% Else %> addMainItem("/calendar/welcome.asp","",81,"center","","",0,0,"","","","",""); <% End If %> <% End If %> defineSubmenuProperties(135,"center","center",-3,0,"","","","","","",""); Currently this file (named custom.js for example) will start throwing js errors, because the server doesnt seem to recognize the asp code in it and therefore does not parse it. I know I need to somehow specify that a .js file should also be treated like an .asp file and run through parsing it. However I am not sure how to go about doing this. Here is what I've tried so far... Under the Server node in IIS under HANDLER MAPPINGS I created a new Script Map with the following settings. Request Path: *.js Executable: C:\Windows\System32\inetsrv\asp.dll Name: ASPClassicInJSFiles Mapping: Invoke Handler only if request is mapped to : File Verbs: All verbs Access: Script I also created a similar handler under the site node itself. Under MIME Types .js is defined as application/x-javascript None of these work. If I simply rename the file to have .asp extension then things work, however this app is poorly coded and has literally 100's of files with the .js files included in them under various names and locations, so rename, search and replace is the last option I have.

  • Howto project a planar polygon on a plane in 3d-space

    - by sum1stolemyname
    I want to project my Polygon along a vector to a plane in 3d Space. I would preferably use a single transformation matrix to do this, but I don't know how to build a matrix of this kind. Given the plane's parameters (ax+by+cz+d), the world coordinates of my Polygon. As stated in the the headline, all vertices of my polygon lie in another plane. the direction vector along which to project my Polygon (currently the polygon's plane's normal vector) goal -a 4x4 transformation matrix which performs the required projection, or some insight on how to construct one myself

  • WCF: Use a Message Contract to make a Soap Header

    - by Vaccano
    I need to add a soap header to my web service. I plan to use this to validate my clients (Windows Mobile Devices). I found this link: http://www.c-sharpcorner.com/UploadFile/rog_21/soapheaders05172007120046PM/soapheaders.aspx Which is exactly what I want to do. But it is not written for WCF. I have done some research and I seem to be paralyzed by the number of options. I basically want to add a simple header to my soap object that will be a user name and password. The client does not use WCF, so the soap header needs to just be a normal soap header. Any Sample code or shoves in the right direction would be appreciated.

  • How well do zippers perform in practice, and when should they be used?

    - by Rob
    I think that the zipper is a beautiful idea; it elegantly provides a way to walk a list or tree and make what appear to be local updates in a functional way. Asymptotically, the costs appear to be reasonable. But traversing the data structure requires memory allocation at each iteration, where a normal list or tree traversal is just pointer chasing. This seems expensive (please correct me if I am wrong). Are the costs prohibitive? And what under what circumstances would it be reasonable to use a zipper?

  • Openfire scalability question XMPP Server

    - by candoyo
    Hello! Do you guys know how well openfire scales? My users will be using the application to do normal chatting like msn no file transfer for now. We will be using Amazon's EC2 server to run the chat server we would like to support over 1 Million users in total and around 30-50K active users during peak times. Since clustering is now opensource, I though Openfire might be the way to go, how much will it cost for the coherence license or can I bipass that somehow? Also, I wanted to develop plugin for Openfire if we go with it. Any pointers on how to set up a dev env and get going would be helpful too! Thanks ya'all! :)

  • OOP: how much program logic should be encapsulated within related objects/classes as methods?

    - by Andrew
    I have a simple program which can have an admin user or just a normal user. The program also has two classes: for UserAccount and AdminAccount. The things an admin will need to do (use cases) include Add_Account, Remove_Account, and so on. My question is, should I try to encapsulate these use-cases into the objects? Only someone who is an Admin, logged in with an AdminAccount, should be able to add and remove other accounts. I could have a class-less Sub-procedure that adds new UserAccount objects to the system and is called when an admin presses the 'Add Account' button. Alternatively, I could place that procedure as a method inside the AdminAccount object, and have the button event execute some code like 'Admin.AddUser(name, password).' I'm more inclined to go with the first option, but I'm not sure how far this OO business is supposed to go.

  • Asp.Net MVC 2 Client validation implementation for Enterprise Library Validation Block

    - by er-v
    Hello to everybody. I've found a very good article about how to use EntLib Validation Block for server validation in MVC 2. But as there pointed out The current design of EntLib’s Validation Application Block uses the Composite pattern; that is, when we ask for validation for an object, it returns back a single validator object that contains a list of all the validation work to be done. While this is very convenient from a normal usage scenario, the unfortunate side-effect is that we can’t “peek inside” to see what the individual validations are that it’s doing, and therefore can’t generate the appropriate client-side validation hints. So how is it possible to implement client side validation for EntLib? Is there work around?

  • linux user login/logout log for computer restriction

    - by Cedric
    Hi ! I would like to know how to log the login and logout of a user. I know it's possible to use the command "last". But this command is based on a file that has a r/w permission for the user, hence the possibility to change these data. I would like to log these data over two months. Why would I like to do that ? In fact, I would like to prevent a normal user to use a computer more than an hour a day - except week-ends, and 10 hours in total a week. Cedric System used : kubuntu, Programming language : bash script

  • initializer_list and move semantics

    - by FredOverflow
    Am I allowed to move elements out of a std::initializer_list<T>? #include <initializer_list> #include <utility> template<typename T> void foo(std::initializer_list<T> list) { for (auto it = list.begin(); it != list.end(); ++it) { bar(std::move(*it)); // kosher? } } Since std::intializer_list<T> requires special compiler attention and does not have value semantics like normal containers of the C++ standard library, I'd rather be safe than sorry and ask.

  • Updatepanel refresh messing up JqueryUI in IE7

    - by o-logn
    Hey everyone, This is a bit of a long shot as I don't have access to the code at the moment. However, there's nothing 'special' about the code. I'm using a combination of JqueryUI and ASP.NET UpdatePanels. If I click any of the trigger controls (asp.net button), the partial-postbacks are fine. However, if I click on a trigger control after clicking on a JQueryUI button, then the entire layout messes up and a lot of the content moves upwards. I can just about reach a JQueryUI button, and when I click that, the layout returns to normal and everything's fine until I click the trigger control again. The page works fine in all latest browsers, but this problem appears in IE 7. I hope maybe someone has come across a similar problem in IE 7 and found a workaround/solution. I've been trying to fix it for a couple of days, but no luck. Thanks for any advice.

I am compiling for 3.1.2 - It works fine in the simulator but when I "build" for the Device, it gives me this line of errors: Link /Users/me/Apps/myapp/build/app.build/Debug-iphoneos/app.build/objects-normal/armv7/appname In /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator3.1.3.sdk/user/lib/libz.dylib, missing required architecture armv7 in file then the actual failure occurs on: Command /Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc-4.2 failed with exit code 1 Any help would be greatly appreciated

  • Can I debug with python debugger when using py.test somehow?

    - by Joel
    I am using py.test for unit testing my python program. I wish to debug my test code with the python debugger the normal way (by which i mean pdb.set_trace() in the code) but I can't make it work. Putting pdb.set_trace() in the code doesn't work (raises IOError: reading from stdin while output is captured). I have also tried running py.test with the option --pdb but that doesn't seem to do the trick if I want to explore what happens before my assertion. It breaks when an assertion fails, and moving on from that line means terminating the program. Does anyone know a way to get debugging, or is debugging and py.test just not meant to be together?

  • How to configure Transparent IP Address Sharing (TAS) on a Mediatrix 4102 with DGW 2.0 firmware?

    - by Pascal Bourque
    I am making the switch to VoIP. I chose voip.ms as my service provider and Mediatrix 4102 as my ATA. One reason why I chose the Mediatrix over other popular consumer ATAs is that it's supposed to be easy to place it in front of the router, so it can give priority to its own upstream traffic over the home network's upstream traffic. This is supposed to work transparently, with the ATA and router sharing the same public IP address (the one obtained from the modem). They call this feaure Transparent IP Address Sharing, or TAS. Their promotional brochure describes it like this: The Mediatrix 4102 also uses its innovative TAS (Transparent IP Address Sharing) technology and an embedded PPPoE client to allow the PC (or router) connected to the second Ethernet port to have the same public IP address, eliminating the need for private IP addresses or address translations. I am interested by this feature because my router, an Apple Time Capsule, doesn't support QoS and cannot give priority to the voice packets if the ATA is behind the router. However, after hours of searching the web, reading the documentation, and good ol' trial and error, I haven't been able to configure the Mediatrix to run in this mode. Then I found a version of the manual that looks like it was for a previous version of the firmware (SIP), where there is an entire section dedicated to configuring TAS (starting at page 209). But my Mediatrix comes with the DGW 2.0 firmware, whose documentation does not mention TAS at all. So I tried to follow the TAS setup instructions from the SIP documentation and apply them to my DGW firmware, using the Variable Mapping Between SIP v5.0 and DGW v2.0 document as a reference, but no success. Some required SIP variables don't have an equivalent in DGW. So it looks like the DGW firmware does not support TAS at all, or if it does they are not doing anything to help us set it up. So right now, the Mediatrix is behind the router and VoIP works perfectly except when my upstream bandwidth is saturated. My questions are: Is downgrading to SIP firmware the only way to have my Mediatrix 4102 run in TAS mode? If not, anybody knows how to setup TAS on the DGW firmware? Is TAS mode the only way to give priority to the voice packets if I want to keep my current router (Apple Time Capsule)? Thanks!

  • Problems migrating an EBS backed instance over AWS Regions

    - by gshankar
    Note: I asked this question on the EC2 forums too but haven't received any love there. Hopefully the ServerFault community will be more awesome. The new AWS Sydney region opening up is something that we've been waiting for for a long time but I'm having a lot of trouble migrating our instances over from N. California. I managed to migrate 1 instance over using CloudyScripts to move a snapshot and then firing up a new instance in the Sydney region. This was a very new instance so both the source and destination were running on a Ubuntu 12.04 LTS server and I had no issues there. However, the rest of our instances are all Ubuntu 10.04 LTS and with these, I'm having a lot of problems. I've tried following: 1- following the AWS whitepaper on moving instances which was given to us at the recent Customer Appreciation Day in Sydney where the new region was launched. The problem with this approach was with the last step (Step 19) here you register the image: ec2-register -s snap-0f62ec3f -n "Wombat" -d "migrated Wombat" --region ap-southeast-2 -a x86_64 --kernel aki-937e2ed6 --block-device-mapping "/dev/sdk=ephemeral0" I keep getting this error: Client.InvalidAMIID.NotFound: The AMI ID 'ami-937e2ed6' does not exist which I think is due to the kernel_id not existing in the Sydney region? 2- Using CloudyScripts to move a snapshot and then creating a new volume and attaching to a new instance in Sydney This results in the instance just hanging on boot and failing the status checks. I can't SSH in or look at the server log I suspect that my issue is with finding the right kernel_id for the volume in the new region. However I can't seem to work out how to go about finding this kernel_id, the ones I've tried (from the original instance) don't result in the Client.InvalidAMIID.NotFound: The AMI ID 'ami-937e2ed6' error and any other kernel_id just won't boot. I've tried both 12.04 and 10.04 versions of Ubuntu. Nothing seems to work, I've been banging my head against a wall for a while now, please help! New (broken) instance i-a1acda9b ami-9b8611a1 aki-31990e0b Source instance i-08a6664e ami-b37e2ef6 aki-937e2ed6 p.s. I also tried following this guide on updating my Ubuntu LTS version to 12.04 before doing the migration but it didn't seem to work either, still getting stuck on updating the kernel_id http://ubuntu-smoser.blogspot.com.au/2010/04/upgrading-ebs-instance.html

  • How can i query for null values in entity framework?

    - by AZ
    I want to execute a query like this var result = from entry in table where entry.something == null select entry; and get an IS NULL generated. Edited: After the first two answers i feel the need to clarify that I'm using Entity Framework and not Linq to SQL. The object.Equals() method does not seem to work in EF. Edit no.2: The above query works as intended. It correctly generates IS NULL. My production code however was var value = null; var result = from entry in table where entry.something == value select entry; and the generated SQL was something = @p; @p = NULL. It seems that EF correctly translates the constant expression but if a variable is involved it treats it just like a normal comparison. Makes sense actually. I'll close this question

  • How to create program that can be run by: #service myservice start

    - by Saif Bechan
    I am new to Linux and want to know what kind of programs can be run by using. #service myservice start And the programs stays on until stopped. Are they normal c++ programs or are they different. In some tutorials i have seen that they use ./myprogram to start a program. Another thing I have seen is the usage of .sh files. One last type of program i see is executed by the command: #/usr/bin/myprogramm Can someone explain the difference between these or point me to a basic tutorial/guide.

  • How do I refresh TinyMCE for the code that I add with JavaScript

    - by Sam Kong
    Hi, I need to insert code for flash to TinyMCE with JavaScript. If I insert the same code using HTML menu of TinyMCE, it automatically add flash icon to the editor. But if I insert the code using JavaScript, the actual code is inserted but it shows nothing on the screen. One trick I found is toggle TinyMCE to normal textarea and back to TinyMCE. Then, it shows the flash icon. Is there a better way to do that? Thanks. Sam

  • How to remotely control a Windows Service with ServiceController?

    - by Amokrane
    Hi, I'm trying to control Windows Services that are installed in a remote computer. I'm using the ServiceController class. I have this: ServiceController svc = new ServiceController("MyWindowsService", "COMPUTER_NAME"); With this, I can get the status of the Windows Service like this: string status = svc.Status.ToString(); But I can't control the Windows Service (by doing svc.Start(); or svc.Stop();). I get the following exception: Cannot open Servicexxx service on computer 'COMPUTER_NAME' That's normal, I suppose there is something to do with access permissions. But how? I've looked into Google but didn't find what I was looking for. However I often read something related to impersonation, but I don't know what that means. NB: The local and remote computers are both running Win XP Pro. Thanks.

  • How do I get the latest FastCGI and PHP versions to peacefully coexist on IIS 6?

    - by BHelman
    I have been going round and round trying to get any sort of PHP running on IIS 6. I somehow managed to successfully get version 5.1.4 running using the php5isapi.dll file. However, I want to upgrade a website to begin using a Content Management System. I have never dug into CMS before so I'm open to programs that are easy to use. I am currently looking into TomatoCMS and ImpressCMS - but that's beside the point. I have never done an installation with PHP before and I think I'm getting familiar with how it works. However the current situation is this. Microsoft's Web Platform Installer 2.0 installed FastCGI for me. I need to upgrade to PHP 5.3.1 for a CMS system. So I downloaded the Windows installer and let it go at it. After consulting several other blog articles, I believe I know how it is supposed to work but I am currently not having luck. THE SETUP *.php is a registered extension in IIS 6 for all websites (on Win 2k3). The application that it calls is C:\Windows\system32\inetsvr\fcgiext.dll, like it should. The fcgiext.ini config has the proper lines: [Types] php=PHP [PHP] ext=C:\program files\PHP\php-cgi.exe And the php.ini file also has the correct configs. All extensions are disabled and I changed the correct things for FastCGI. And everything is registered correctly with the PATH variable. Everything is exactly how it should be. BUT when I launch the "info.php" page () on another computer, I get the following error: FastCGI Error The FastCGI Handler was unable to process the request. Error Details: * Section [PHP] not found in config file. * Error Number: 1413 (0x80070585). * Error Description: Invalid index. HTTP Error 500 - Server Error. Internet Information Services (IIS) A quick Google search reveals that I have it all setup correctly as far as the INI's go and the mapping of the php extension. I am completely at a loss. Does anyone have any suggestions? Although the server is hosting three small websites, I don't really care what I have to do to it to get it to work.

  • How do I debug random Timeout::Error: execution expired

    - by ChrisH
    We are using Rails 2.3.5 and have been experiencing seemingly random Timeout::Error: execution expired errors. The errors reported by Hoptoad are not consistently in any particular controller and show up everywhere from user sessions to account settings to some of our core functionality controllers. The vast majority of requests do not Timeout but there are enough to cause concern. Is this normal? If so, what are some things to look at to decrease the occurance? If not, has anyone run into this and what are some common problems that can trigger an error like this.

  • Is it safe to lock a static variable in a non-static class?

    - by Dario Solera
    I've got a class that manages a shared resource. Now, since access to the resource depends on many parameters, this class is instantiated and disposed several times during the normal execution of the program. The shared resource does not support concurrency, so some kind of locking is needed. The first thing that came into my mind is having a static instance in the class, and acquire locks on it, like this: // This thing is static! static readonly object MyLock = new object(); // This thing is NOT static! MyResource _resource = ...; public DoSomeWork() { lock(MyLock) { _resource.Access(); } } Does that make sense, or would you use another approach?
