• How Do I Update a Table From Another Table Only If the Result Count is 1?

  - by Russ Bradberry

  I have a table of 2 tables in a one to many relationship. I want to run an update script that will update the table with the FK of the related table only if there is one result (because if there is multiple then we need to decide which one to use, in another method) Here is what I have so far: UPDATE import_hourly_event_reports i SET i.banner_id = b.banner_id FROM banner b JOIN plan p ON b.plan_id = p.id WHERE b.campain_id = i.campaign_id AND b.size_id = i.size_id AND p.site_id = i.site_id HAVING COUNT(b.banner_id) = 1 As you can see, the HAVING clause doesn't quite work as I'd expect it. I only want to update the row in the import table with the id of the banner from the banner table if the count is equal to 1.

• RESTful API: How to handle translated textfields in representations?

  - by Jan P.

  I am designing a RESTful API for a booking application. There are accommodations that you can request a list or the details. As the application targets a multi-language audience, the descriptions are (sometimes) available in different languages. Now I'm not sure how to handle these translations in the representation of an accommodation. Without the multiple languages I would make "description" a field or the accommodation object, quite simple. Any idea how to solve this elegantly? My current idea: Add a list of descriptions with text<-culture pairs instead of the description field and an additional subressource /descriptions to the accommodation for the creating (POST), updating (PUT) and deleting (DELETE) of new translations.

• What's the best way to build software to not require the newest glibc?

  - by ZorbaTHut

  I'm attempting to build a binary package that can be run on multiple Linux distributions. It's currently built on Ubuntu 10.04, but it fails on Ubuntu 8.04 with the following error: ./test: /usr/lib/libstdc++.so.6: version `GLIBCXX_3.4.11' not found (required by ./test) ./test: /usr/lib/libstdc.so.6: version `GLIBC_2.11' not found (required by ./test) What's the preferred way to solve this problem? Is there a way to install an old glibc on a new box and build against it, or do I have to build on an old distribution? And if I build against an old glibc, will it work on a new glibc? Or, alternatively, are there just some handy compiler flags or packages I could install to solve the problem?

  - by ikurtz

  im new to java and i have a question regarding Synchronized. i have the following code for writing to network (simple implementation for now): public void networkSendData(byte[] data){ try { out.write(data); out.flush(); } catch (IOException e) { } } i was wondering if there is a need for block level Synchronized here as im am writing the whole data at once. or is there a chance for race condition? i ask because the data to write is coming for multiple sources. thank you.

• 'Best' way to pull data relative to a div?

  - by acidzombie24

  This answer suggested i should put my data in JS instead of a textarea. Thinking about it i could have scripts and do something like myarray[i]="data" where i is the index of my for loop. However when i click a div how do i find out what i is? I have used var data = $(this).parent('.parent').find('.valuestr').eq(0).val(); which is extremely simple. Should i use a script or should i continue to do it with a textarea? if i should use a script 1) Whats the easiest way to find i and 2) Is it bad pratice to have dozens or hundreds of <script> in my html? or i can go through the loop twice but i still dont know the easiest way to find i. I would have to store it somewhere or go through multiple tags and count them.

• How to save/export a DOM element to an image?

  - by Don Don

  Hi, I have a web page which has a form element (with its ID known) and inside the form there are multiple DIVs, and the position of each div may be changed. What I'd like to do is: a) Save the current state of this form // var currentForm=document.forms['myFrm'].innerHTML; would probably suffice... b) Save or export the entire form with the most current position of each DIV to an image file. // how to save/export the javascript var of currentForm to an image file is the key question. Any help/pointer would be appreciated.

• Update database using restful ASP.NET MVC 1.0

  - by Mike

  We are building an MVC 1.0 application right now and using Linq - SQL for our DAL. Following the restful approach we have multiple action events depending on if you are updating or loading or what not. The two that I'm concerned with at this point are the edit and update action methods. Here is the signatures. public ActionResult Update(int customerId, int Id, AggregateModel viewModel) public ActionResult Edit(int customerId, int Id, AggregateModel viewModel) So the idea is that in the Edit method we load up our viewModel and pass it to the view. The user makes changes to the model and then posts back to the Update method. The first thing I could think of to do would be to get the viewModel from the database again, copy the changes in one by one from the posted back model and then submit it back. This would work but does seem clunky to me. What is the best way to insert those changes into the database at this point?

• Get smallest date for each element in access query

  - by skerit

  So I have a table containing different elements and dates. It basically looks like this: actieElement beginDatum 1 1/01/2010 1 1/01/2010 1 10/01/2010 2 1/02/2010 2 3/02/2010 What I now need is the smallest date for every actieElement. I've found a solution using a simple GROUP BY statement, but that way the query loses its scope and you can't change anything anymore. Without the GROUP BY statement I get multiple dates for every actieElement because certain dates are the same. I thought of something like this, but it also does not work as it would give the subquery more then 1 record: SELECT s1.actieElement, s1.begindatum FROM tblActieElementLink AS s1 WHERE (((s1.actieElement)=(SELECT TOP 1 (s2.actieElement) FROM tblActieElementLink s2 WHERE s1.actieElement = s2.actieElement ORDER BY s2.begindatum ASC)));

• efficiently compare two BitArrays of the same length

  - by BobTurbo

  How would I do this? I am trying to count when both arrays have the same value of TRUE/1 at the same index. As you can see, my code has multiple bitarrays and is looping through each one and comparing them with a comparisonArray with another loop. It doesn't seem to be very efficient and I need it to be. foreach (bitArrayTuple in bitarryList) { for (int i = 0; i < arrayLength; i++) if (bArrayTuple.Item2[i] && comparisonArray[i]) bitArrayTuple.Item1++; } where Item1 is the count and Item2 is a bitarray.

• How do you manage web navigation info in your application?

  - by Dave

  I’m building an application where different users will have different menu items available to them depending on what they’ve paid for. There will also be multiple levels to the menu hierarchy. What’s the best approach to this problem? I’m assuming I need a database table that represents the menu hierarchy, including the parent-child relationships of the nodes in the navigation as well as the sorting of the items. Then another table which I use to manage whether a user is authorized to access a particular item in that table. When I render the view, I’d reference the menus, and the access rights of the user to output the menu, and I’d also need a function to check that same authorization from each controller in case a user manually types in a URL of a controller they’re not supposed to have access to. Is this the right approach? Any suggestions for caching this to prevent the constant look-ups of this type of info? I’m open to any suggestions on how you may have approached this type of requirement.

• C++ include header conventions

  - by user231536

  Suppose I have a file X.h which defines a class X, whose methods are implemented in X.cc. The file X.h includes a file Y.h because it needs Y to define class X. In X.cc, we can refer to Y because X.h has already included Y.h. Should I still include Y.h in X.cc ? I understand that I don't need to and I can depend on header guards to prevent multiple inclusions. But on the one hand, including Y.h makes X.cc a little more independent of X.h (can't be completely independent of course). What is the accepted practice? Another example: including <iostream> in both .h and .cc files. I see some people do this and some don't.

• memcpy() safety on adjacent memory regions

  - by JaredC

  I recently asked a question on using volatile and was directed to read some very informative articles from Intel and others discussing memory barriers and their uses. After reading these articles I have become quite paranoid though. I have a 64-bit machine. Is it safe to memcpy into adjacent, non-overlapping regions of memory from multiple threads? For example, say I have a buffer: char buff[10]; Is it always safe for one thread to memcpy into the first 5 bytes while a second thread copies into the last 5 bytes? My gut reaction (and some simple tests) indicate that this is completely safe, but I have been unable to find documentation anywhere that can completely convince me.

• c++ thread running time

  - by chnet

  I want to know whether I can calculate the running time for each thread. I implement a multithread program in C++ using pthread. As we know, each thread will compete the CPU. Can I use clock() function to calculate the actual number of CPU clocks each thread consumes? my program looks like: Class Thread () { Start(); Run(); Computing(); }; Start() is to start multiple threads. Then each thread will run Computing function to do something. My question is how I can calculate the running time of each thread for Computing function

• Rebind a unbind click

  - by Antonio Ortiz

  I am using this library that allows you to create a more elegant alert box (you can even use images!); I used it with a click function and it works! A nice container opens with a close button, GREAT! I noticed if you happen to click more than once on the link you assigned, it keeps firing. So multiple images begin to propagate. I used the unbind method, but it cancels the link permanently (until refresh etc.). I was surprised to see the library doesn't compensate for this little problem, so I am wondering if you could rebind the click when you close the image window so it starts from the beginning. $(".shopFrag").click(function(){ Messi.img("_images/wishlist.jpg"); $(".shopFrag").unbind('click'); });

• What is the recommended way to split messages in send pipelines?

  - by ToxicAvenger

  I need to split a bizTalk message in the send pipeline. This is easy with disassemblers in receive pipelines, but doesn't work in send pipelines (makes sense). So what is the recommended way to do it? The only easy way to do it is to write the outbound message to file, then reprocess it using a receive pipeline with a disassembler, and then send the generated messages through a outbound pipeline. Honestly, I don't need the additional roundtrip through the message box, but I don't want to create a custom send adapter. Any other suggestions? Any easy way to save messages with multiple parts using the ootb file adapter?

• Concatenating a Text in front of Individual Database Records with Tcl

  - by DFM

  Hello: In short, currently I am using the following code to pull records from multiple tables in a Sqlite Db and insert them in a single combobox ($SearchBar): set SrchVals1 [db eval {SELECT DISTINCT Stitle From Subcontract Order By Stitle ASC}] set SrchVals2 [db eval {... set SrchVals3 ... set SrchValsALL [concat $SrchVals1 $SrchVals2 $SrchVals3] $SearchBar configure -value $SrchValsAll For the variable "SrchVals1", I am trying to figure out a way to concatenate the text "Sub: " to each individual record in SrchVals1. For example, if SrchVals1 shows the following records in the combobox: First Title Second Title Third Title I would like to concatenate so that the records in the combobox look like this: Sub: First Title Sub: Second Title Sub: Third Title I understand that I might have to use a foreach statement; however, I am having no luck writing one that adds "Sub: " in front of each record, as opposed to one. This seems like something that should be pretty easy, but I cannot seem to figure it out. Does anyone know how I can achieve these results? Thank you, DFM

• In ASP.NET MVC, how does response.redirect work?

  - by Swoop

  I have used response.redirect in classic ASP and ASP.NET webforms. However, with MVC 2.0, I am running into something peculiar. I have a private method in a controller class that is used by multiple controller methods to help load and validate some information. This private method is setup to redirect if a problem is discovered to a generic error message page. The big problem I am noticing is that the calling controller class and page view attempt to complete rendering and loading before the redirect actually takes place. This is annoying in development because the View throws exceptions that I need to ignore before my generic error page finally loads. As mentioned above, I am used to the older model of response.redirect which prevented subsequent code on a page from being executed as the new page would then load. Any help or advice on redirects in MVC would be greatly appreciated.

• Android changing colors with themes

  - by miannelle

  I am trying to provide user settable colors in my app. White text on black background and black text on white background. I have multiple layouts with many listviews, both standard and custom adapters. People have suggested using Themes, but I have had no luck changing the text colors across all layouts. Can anyone show me an actual Theme layout that can accomplish this? I can easily change the background colors using myscreen.setBackGroundColor(xx), but when I try to change the text with a theme, it also changes spinner text as well.

• Excel + Web Data

  - by user348152

  I've spent hours scouring the net for anything to do with VBA calling data from the web in excel and nothing provides a tutorial on how to do so, only complicated examples un-related to what I want to do. I want to pull data from either a .html or .xml site, doesn't matter, via Excel and find specific points in that data. I can find specific points but don't know how to get the data or scroll through multiple lines. I've done this exact sort of thing in mIRC (sort of C code). http://eve-central.com/home/quicklook.html?typeid=438 http://api.eve-central.com/api/quicklook?typeid=438 Those are two examples, using roughly the same data I'd like to retrieve. It'd be FAR more specific with at most 100 or so different values. I'd like to be TAUGHT how to do it, not given the code to do it, or if you must explain each part with comments in-depth please. Thanks Nick

• Status corresponding to Minimum value

  - by Lijo

  Hi Team, I am using SQL Server 2005. I have a table as given below. There can be multiple cancellations for each FundingID. I want to select the FundingCancellationReason corrersponding to minimum date for each funding. I wrote a query as follows. It is an SQL error 1) Could you please help me to avoid the SQL Error? 2) Is there any better logic to achieve the same? CREATE TABLE #FundingCancellation( [FundingCancellationID] INT IDENTITY(1,1) NOT NULL, [FundingID] INT , FundingCancellationDt SMALLDATETIME , FundingCancellationReason VARCHAR(50) ) SELECT FundingID, MIN(FundingCancellationDt), ( SELECT FundingCancellationReason FROM #FundingCancellation FC2 WHERE FC1.FundingID = FC2.FundingID AND FC2.FundingCancellationDt = MIN(FundingCancellationDt) ) [Reason Corresponding Minimum Date] FROM #FundingCancellation FC1 GROUP BY FundingID -- An aggregate may not appear in the WHERE clause unless it is in a subquery contained in a HAVING clause or a select list, and the column being aggregated is an outer reference. I have seen the similar approach working in a somewhat complex query. So I believe tehre will be a way to correct my query Thanks Lijo

• global applied stylesheet link on debian box

  - by James

  Hi there, Having some trouble identifying what is wrong with my link to an external CSS stylesheet... I am using a debian box to host some things... including a file i am accessing page.py which is located in /var/www/cgi-bin. I need this page to link to a css file which currently has the pathname /var/www/styles.css. Now I know I could link as: <link rel="stylesheet" href="**../styles.css**" type="text/css"> and the problem is solved but I would rather have a 'global' link, that I can use in other py files elsewhere in my filesystem and they will all point to /var/www/styles.css The information I have searched suggests that <link rel="stylesheet" href="**/var/www/styles.css**" type="text/css"> should work fine... but it doesn't. I have tried multiple combinations of everything I know but it doesn't seem to link as I would expect. Can anyone point me in the right direction?
