• How do i deploy UAT and Development SharePoint solution on the same server ?

  - by Nikhil Vaghela

  I am working on a SharePoint 2010 Server and i have following items in my SharePoint solution Couple of web parts State Machine Work flow (which will be integrated to an Infopath form library) Infopath task edit forms Lets say this solutions is deployed to http://[SharePoint201Server]:[PortNumber-x]/ This is the only server i have (No extra server for UAT), and what ever has been done so far needs to be given for user acceptance testing (UAT). I may create one more site at http://[SharePoint201Server]:[PortNumber-y]/ for it. My problme is that how do i maintain two copies of my source code ? I will have to continue development on the same set of source code for next UAT release. I simply can not create simple copies of the source code as it will have same Assembly name and feature id, etc..As if i do so, any changes on under Development source code would affect UAT assemblies. One thing i can do is to create seperate projects for UAT and Development with different Features and Assembly names, but is not that too much of an unneccesory work ? What can be the best approach in such situation ?

• XSD data set with Oracle database

  - by Ed Woodcock

  Hi folks, I'm having a major issue with an XSD dataset mapping thingy that I'm using within my current project. We are using XSDs for some data abstraction (it's quicker and debatably more maintainable that using Parameterised SQL or a StoredProc), and on my machine (running in the VS development environment) thy're working fine. However, on the Pre-production server we use for our testing, the XSDs are not working correctly: some method calls will fail with the following error: System.ArgumentException: Value does not fall within the expected range. at Oracle.DataAccess.Client.OracleParameter.set_DbType(DbType value) Has anyone ever encountered this issue before? The methods being called are simple select statements using 1-3 parameters, and as I said before they work fine on my machine.

• How to validate ToCheckList jQuery plugin (or multiple select fields)?

  - by Chad

  Anyone ever use the toChecklist jQuery plugin? It basically turns a multi-select box into a list of checkboxes. Makes it easier for users to understand that they can choose more than one item - excellent plugin. However, I'm trying to make sure that users on my site pick at least 1 item in the list. ToChecklist has the capability of limiting the selection to a max value, but not minimum. I'm already using the jQuery validate plugin to validate the whole form, any ideas to get it to work against a multi-select box (which would then hopefully just work with toChecklist)? Thanks in advance!

• Create a thumbnail of a dwg in in a linux envrionment

  - by Kyle

  Creating a ruby on rails site that uses RMagick to create thumbnails for many types of images. RMagick cannot read dwg files however. I've tried a few things, looked into the Java library JDWGLib, which would probably allow me to write a converter, but it would be a total from the ground up solution, where I just need a thumbnail. Also considered using a viewer program to open the file in a remote X session and do a screen capture, however I'm not sure how I could ever guarantee that the viewer had completed opening when I took the screenshot. I'm not concerned with being able to manipulate the file other than to create the thumbnail. It is going to be used for commercial purposes, so any libraries used need to be compatible.

• FFmpeg and qt, Unable to find a suitable output format for '>'

  - by Spredzy

  Hi all, I'm trying to execute a ffmpeg operation through Qt I would like to execute this line : ./ffmpeg -t 10 -i temp1 -f mpeg - > temp2 When I execute through the terminal, it works perfectly fine.

• How to make an HTTP request in a separate thread with timeout?

  - by Vitaly

  Hi, I haven't programmed in Delphi for a while and frankly didn't think I'll ever have to but... Here I am, desperately trying to find some information on the matter and it's so scarce nowadays, I can't find anything. So maybe you guys could help me out. Currently my application uses Synapse library to make HTTP calls, but it doesn't allow for setting a timeout. Usually, that's not a big problem, but now I absolutely must to have a timeout to handle any connectivity issues nicely. What I'm looking for, is a library (synchronous or not) that will allow making HTTP requests absolutely transparent for the user with no visible or hidden delays. I can't immediately kill a thread right now, and with possibility of many frequent requests to the server that is not responding, it's no good.

• What do you do when every possible business idea is already taken?

  - by jonathanconway

  I have a bit of free time and lots of enthusiasm for software and the web. I want to make a start-up, to sell kind of product or online service, but I'm having a hard time coming up with business ideas that haven't already been implemented. For example, I thought of making an e-ordering website for ordering food from restaurants online. Good thing I typed it into Google, because the market is already full of hundreds of websites doing the same thing and competing heavily. The same thing has happened with so many other business ideas I've become excited and passionate about - they're all taken. What's your response to this? Do you agree that all the good ideas seem to be taken? Or do you think there is room for new businesses, and that I'm just not thinking (or looking) hard enough? Have you ever tried idea after idea, only to find that it was already being done, and you had to move onto something else?

• Do i *have* to use ObservableCollection in Silverlight WCF client?

  - by Simon_Weaver

  When accessing Silverlight in WCF you get proxies generated with ObservableCollection Thats fine when you're databinding, but a little clumsy when you're just calling a method. For instance the following service method : [OperationContract] public SearchOrdersMsgOut SearchOrders(ShippingStatusType[] shippingStatuses, string[] orderId) { } gets generated with ObservableCollection. What! They're just parameters. Why would I ever want to 'observe' them? I'm fine if I have to do this - but it seems like there should be a way to force simple array structures when I know I'm never databinding - especially on input messages. I'd much rather do this : searchCriteria.PaymentStatus = new [] { PaymentStatusType.PaymentFailed, PaymentStatusType.Unpaid }; than this : searchCriteria.PaymentStatus = new ObservableCollection<PaymentStatusType> { PaymentStatusType.PaymentFailed, PaymentStatusType.Unpaid }; Is there a way? PS. I do actually use a SearchCriteria object for my search criteria - but I simplified for this example wondering if parameters were handled differently.

• Handling Java stdout and stderr in Perl

  - by syker

  I am trying to run a Java program from my Perl script. I would like to avoid using System.exit(1) and System.exit(-1) commands in Java. I am however printing to STDOUT and STDERR from Java. In my Perl script, I am reading from Java's stdout and using that line by line output. How do I print stderr and fail if I ever see stderr? This is what I have so far: my $java_command = ...; open(DATA, ">$java_command"); while (<DATA>) { chomp($_); .... .... }

• ASP.NET MVC reminds me of old Classic ASP spaghetti code...

  - by EdenMachine

  I just went through some MVC tutorials after checking this site out for a while. Is it just me, or does MVC View pages brinig back HORRIBLE flashbacks of Classic ASP spaghetti code with all the jumping in and out of HTML and ASP.NET with yellow delimiters everywhere making it impossible to read? What ever happened to the importance of code/design separation?? I was really sold on the new technology until the tutorials hit the View page development section. Or am I missing something? (And don't say you can use the template to help because it's jsut moving the spaghetti to another location - sweeps it under the rug - it doesn't fix the problem)

• Combining GPL with MPL and BSD

  - by thr

  I have a software project I want to release under GPLv3, it uses two pieces of code that other parties have developed (one is the DLR by Microsoft, which is under the Microsoft Public License and the other piece of code is under the New BSD License). The BSD licensed code is compiled into the same binary as my code (but none of it is changed) The Ms-PL licensed code is compiled into another assembly next to my code and linked at runtime (and none of it is changed what so ever). Can I release my software under GPLv3 and without any legal problems?

• Java: Sockets or RMI?

  - by StillLearning

  Hi, I need to separate our application into a light-weight gui application and a business logic application. This won't be a client/server setup as such, as the 'server' component will only have one client. The other limitation in the application is that it has only one entry/exit point. Therefore if we were to use RMI, it would only ever be on one function. All form data is already wrapped up into a string and passed through one transport area. Should I just use Java Sockets to enhance this application, or go with RMI? Or some other Java technology? I made a previous post outlining the requirements of our application, however it went unanswered. http://stackoverflow.com/questions/2604528/terminal-panel-pc-single-server-solution-client-server-or-rdp Cheers.

• Why would I do an inner join on a non-distinct field?

  - by froadie

  I just came across a query that does an inner join on a non-distinct field. I've never seen this before and I'm a little confused about this usage. Something like: SELECT distinct all, my, stuff FROM myTable INNER JOIN myOtherTable ON myTable.nonDistinctField = myOtherTable.nonDistinctField (WHERE some filters here...) I'm not quite sure what my question is or how to phrase it, or why exactly this confuses me, but I was wondering if anyone could explain why someone would need to do an inner join on a non-distinct field and then select only distinct values...? Is there ever a legitimate use of an inner join on a non-distinct field? What would be the purpose? And if there's is a legitimate reason for such a query, can you give examples of where it would be used?

• fcgio.cpp: In destructor 'virtual fcgi_streambuf::~fcgi_streambuf()':

• Explanation for expires header

  - by sushil bharwani

  I have a joomla application working on Apache.To improve site performace we have written a .htaccess file to root of the application with setting a far future expires header to all the static content. As desired first time the files load in fresh with 200 status code. when again click on the same link many of the files are served directly from cache. I need explanation for two things When i press f5 then a number of files load with 304 status code however i expected them to be coming directly from cache without hitting the server for a status header? When i close the browser and come back to the same page again i see the same thing happening a number of files load with 304 status code although i thought they will load directly from the browser cache? I understand that 304 also servs file from browser cache but i want to avoid the header communication between servers as my static files wont ever change. Also i want to add that my requests are over a https connection does that create any issue.

• WaitForSingleObject( )

  - by Rakesh Agarwal

  I have got myself stuck into a really amazing issue here.The code is like as below. class A { public: A(){ m_event = CreateEvent(NULL, false, false, NULL); // create an event with initial value as non-signalled m_thread = _beginthread(StaticThreadEntry, 0, this); // create a thread } static void StaticThreadEntry(A * obj) { obj->ThreadEntry(); } void ThreadEntry(); }; void A::ThreadEntry() { WaitforSingleObject(m_event,INFINITE); } int main() { A a; SetEvent(m_event); // sets the event to signalled state which causes the running thread to terminate WaitForSingleObject(m_thread, INFINITE); // waits for the thread to terminate return 0; } Problem : When the above code is run,sometimes( 1 out of 5 ) it hangs and the control gets stuck in the call to WaitforSingleObject()( inside the main function ).The code always calls SetEvent() function to ensure that the thread would terminate before calling Wait() function. I do not see any reason why it should ever hang?

• Does SQLite handle non-English locales out of the box?

  - by Andrey Tarantsov

  I have noticed that Google Toolbox for Mac replaces several SQLite built-in functions (LOWER/UPPER, LIKE, GLOB) with its own versions that handle string locales better. So, question to everyone who has SQLite experience: have you ever had any problems with non-English locales in SQLite? Does one really have to do something to properly handle non-English alphabets? What kinds of problems are expected if I use SQLite APIs as-is? (I'm going to use SQLite on the iPhone, but I guess it's the same across all platforms. I've been using Core Data previously and never had any problems, but this time I want to switch to non-ORMed db access.)

• Bad temperature sensors on Foxconn motherboard?

  - by Gawain

  I have a system with a Foxconn V400 series motherboard and AMD Athlon 3000+ processor. Ever since I got it a few years ago the fans (particularly the CPU fan) have been really loud. So recently I installed SpeedFan to see why they were running so fast. SpeedFan reported the CPU temperature to be 32C, and one motherboard sensor at about 26C. But the other two motherboard sensors were reporting 78C and 64C respectively. Naturally the fans were both maxed out because of this, with the CPU fan at 5800rpm and the case fan at 2400rpm. I opened the case and everything inside was literally cool to the touch, with the exception of the CPU heatsink which was slightly warm, but nowhere near 78C. It seems like the temperature sensors are either defective or being read incorrectly. Is there some way I can decrease my fan noise without risking damage to my processor? Some way to ignore those two temp sensors? Any help would be greatly appreciated.

• .odx Files in BizTalk 2009 (VS2008 IDE) Fail to open. "Unspecified Error"

  - by AllenG

  Okay, I'm not sure if this is an SO question, or a ServerFault question, but I figured I'd post here first. I have a BizTalk project which works like a champ for its original design. It's been deployed and it's working fine. Today, I went in to add some new fuctionality by modifying one of my orchestrations. When I attempted to open it, I got a message which simply stated: "The operation could not be completed. Unspecified error." I've closed the IDE and re-opened; I've restarted the machine; I've even allowed Microsoft Updates to run and restart the machine. Everything else opens just fine (.xsd files, .btms, etc.) so it appears only to be the orchestrations which are failing. Has anyone ever encountered a similar issue and resolved it (short of reinstalling BizTalk/VS, or blowing the orchs away and rebuilding)? Any help would be appreciated.

• How can I embed firefox in a GUI application?

  - by PeniWize

  Has anyone ever embedded the firefox web browser technology in their own [unmanaged] C/C++ GUI application in the same way that IE can be embedded as a COM object? (I would like to do this on Linux, not Windows). Are there "better" alternatives to firefox? I'm open to anything as long as I can use it with non-GPL code. My needs are fairly basic; I only need fundamental HTML parsing and display of static local files, but I'd take advantage of more sophisticated technology, if I can get it. I'd like to be able to use JavaScript, but I can get by without it.

• Definitive best practice for injecting, manipulating AJAX data

  - by Nic

  Ever since my foray into AJAX, I've always used the "whatever works" method of manipulating AJAX data returns. I'd like to know what the definitive and modern best practice is for handling data. Is it best practice to generate the HTML via the server script and introduce the returned data on the onComplete function? Should XML/JSON be looked at first before anything? How about manipulating the returned data? Using .live() doesn't seem like it is the most efficient way. I've never seen a definitive answer to this question. Your expertise is much appreciated.

• FxCop giving a warning on private constructor CA1823 and CA1053

  - by Luis Sánchez

  I have a class that looks like the following: Public Class Utilities Public Shared Function blah(userCode As String) As String 'doing some stuff End Function End Class I'm running FxCop 10 on it and it says: "Because type 'Utilities' contains only 'static' ( 'Shared' in Visual Basic) members, add a default private constructor to prevent the compiler from adding a default public constructor." Ok, you're right Mr. FxCop, I'll add a private constructor: Private Utilities() Now I'm having: "It appears that field 'Utilities.Utilities' is never used or is only ever assigned to. Use this field or remove it." Any ideas of what should I do to get rid of both warnings?

• ASP.NET MVC IoC usability

  - by Andrew Florko

  Hello everybody, How often do you use IoC for controllers/DAL in real projects? IoC allows to abstract application from concrete implementation with additional layer of interfaces that should be implemented. But how often concrete implementation changes? Should we really have to do job twice adding method to interface then the implementation if implementation hardly will ever be changed? I took part in about 10 asp.net projects and DAL (ORM-like and not) was never rewritten completely. Watching lots of videos I clearly understand that IoC "is cool" and the really nice way to program, but does it really needed?

• Flash FLVPlayback states

  - by rob5408

  I'm writing my own class to manage a skin for an FLVPlayback component. It works 90% of the time, but sometimes the state get really messed up. Specifically, the video is playing, meaning I can see it play and the VideoEvent.PLAYHEAD_UPDATE event is firing, but when I poll the FLVPlayback component about its playing property, it returns false. I assume this may be because 'buffering' is kind of a subset of 'playing', but I cannot confirm this in the documentation. I guess another way to ask this question is, "Does the FLVPlayback component ever buffer while it is in a stopped state?"

• Do I need to use C3P0 pooling library in my (grails) web application?

  - by fabien7474

  Hi, I am not familiar at all with connection pooling library. I've just discovered it through this blog article) and I am not sure that I should use one in my web application based on grails/hibernate/mysql. So my question is simple : in which situations would you suggest to integrate a connection pooling library into a grails application? Always, Never or only over some connections threshold? P.S. : If you have ever used successfully C3P0 in your web application, I will greatly appreciate to hear your feedback (in terms of visible positive effects).
