  • How do i find out in sql what db name I'm connect to

    - by gjutras
    We have a change control environment where the developers give scripts to change control people to run. we have dev,qa, & production environments. I want to conditionalize a couple segments to do some different things depending on what database the change control person is running my script. If @dbname='dev' then begin --do some dev stuff end If @dbname='QA' then begin --do some qa stuff end If @dbname='Prod' then begin --do some production stuff end How do I get at what the current connected database is and fill @dbname?

  • One Database Field to Hold Survey Answer

    - by yar
    Skipping the question of whether this is bad design (and the question of why I would want/need to do this), I'm just wondering if my 'math' is right... I have n things that need to be put in order (n is always less than 5): thing1 thing2 thing3 ... and I'd like to store these results in a single integer for thing. My initial thought is that (obviously the code will not look like this): thing = thing1 * 1 + thing2 * 2 + thing3 * 4 + thing5 * 8 will always give me a unique value, and that any value for thing will always translate back to its values for thing1...thingn. Is this correct?

  • Writing jQuery functions that allow chaining.

    - by Rich Bradshaw
    I want to write some code that allows me to replace jQuery's animate function with one that does different things, but still allows me to call a secondary function on completion. At the moment, I'm writing lots of code like this; if (cssTransitions) { $("#content_box").css("height",0); window.setTimeout(function() { secondFunction(); }, 600); } else { $("#content_box").animate({ height:0 }, 600, function() { secondFunction(); }); } I'd much rather write a function that looks like this: function slideUpContent(object) { if (cssTransitions) { object.css("height",0); // Not sure how I get a callback here } else { $("#content_box").animate({ height:0 }, 600, function() { }); } } That I could use like this: slideUpContent("#content_box", function(){ secondFunction(); }); But I'm not sure how to get the functionality I need - namely a way to run another function once my one has completed. Can anyone help my rather addled brain?

  • Angularjs code/naming conventions

    - by Dalorzo
    Does anyone know if exists any official or most accepted reference for Angular naming conventions to use when we build our applications? Angular has a lot of different type of components such as filters, directives, services and so on. Wouldn't you agree that having a reference naming convention when we implement them in our applications will make sense? For example: If we need to create new filters how should we name them like [Something]Filter or filter[Something] or something else? And same applies for Controllers, Services, Directives and so on. Other things I wonder about is if variables/functions that belongs to the scope should have an special prefix or suffix. In some situations it may be useful to have a way to differentiate them from functions and other (none angular code).

  • Why does C++ linking use virtually no CPU? (updated)

    - by John
    On a native C++ project, linking right now can take a minute or two, yet during this time CPU drops from 100% during compilation to virtually zero. Does this mean linking is primarily a disk activity? If so, is this the main area an SSD would make big changes? But, why aren't all my OBJ files (or as many as possible) kept in RAM after compilation to avoid this? With 4Gb of RAM I should be able to save a lot of disk access and make it CPU-bound again, no? update: so the obvious follow-up is, can VC++ compiler and linker talk together better to streamline things and keep OBJ files in memory, similar to how Delphi does?

  • How to setup a development Active Directory

    - by Rob
    Does anyone have any suggestions on how to setup a development environment for active directory? We are thinking of using development.contoso.com or something along those lines that is a completely separate envnironment from our production. This will be used for things like Dev SharePoint and possibly a Dev exchange server. Maybe even a dev CRM. We are thinking of setting this up all using virtual machines. Possibly having the production get replicated down on a regular basis as well. Does anyone have an experience with this or any suggestions on what to do or not to do for this?

  • Class decorator to declare static member (e.g., for log4net)?

    - by Ken
    I'm using log4net, and we have a lot of this in our code: public class Foo { private static readonly ILog log = LogManager.GetLogger(typeof(Foo)); .... } One downside is that it means we're pasting this 10-word section all over, and every now and then somebody forgets to change the class name. The log4net FAQ also mentions this alternative possibility, which is even more verbose: public class Foo { private static readonly ILog log = LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType); ... } Is it possible to write a decorator to define this? I'd really like to say simply: [LogMe] // or perhaps: [LogMe("log")] public class Foo { ... } I've done similar things in other languages, but never a statically-compiled language like C#. Can I define class members from a decorator?

  • [org-mode]: repeating task in every Mon, Wed, Fri at 18:00, need help with sexp.

    - by zeroDivisible
    Hello, As I had written in title, I need a little help with improvement of this sexp: * TODO remeber about thingie. SCHEDULED: <%%(or (= 1 (calendar-day-of-week date)) (= 3 (calendar-day-of-week date)) (= 5 (calendar-day-of-week date)))> Now it shows itself in the following days, but I would like to change two things about it: How can I also schedule on specific hours (i.e. 18:00 - 20:00) in the following days How can I made this task repeat itself, just like it repeats itself with <2010-05-13 Wed +1w> (by repetition I mean something like it automatically logs the closing date and time and comes back to the TODO state). I will be grateful for any help. Best regards, Mike.

  • Can I learn the iPhone SDK and complete an app by September?

    - by Kuro
    Hi everyone, I'm wondering if it's realistically possible to learn the iPhone SDK and complete an app by the end of this summer. The app shouldn't be too difficult, it would just interact with my site's API and essentially just fetch, create, and edit resources. I already have a little experience with the SDK (and I'm comfortable with Objective-C), so I'm not completely new to it. Although here I things I don't know how to do and what I'd need to learn: Log in to my site using basic http authentication and store the user's username/password for all future requests Implement a toolbar at the bottom to navigate between different views Fetch and parse xml into list items Do POST/PUT requests to create/edit a resource on my server Are there any good resources available to learn how to do those tasks above? Thanks!

  • C++11: thread_local or array of OpenCL 1.2 cl_kernel objects?

    - by user926918
    I need to run several C++11 threads (GCC 4.7.1) parallely in host. Each of them needs to use a device, say a GPU. As per OpenCL 1.2 spec (p. 357): All OpenCL API calls are thread-safe75 except clSetKernelArg. clSetKernelArg is safe to call from any host thread, and is safe to call re-entrantly so long as concurrent calls operate on different cl_kernel objects. However, the behavior of the cl_kernel object is undefined if clSetKernelArg is called from multiple host threads on the same cl_kernel object at the same time. An elegant way would be to use thread_local cl_kernel objects and the other way I can think of is to use an array of these objects such that i'th thread uses i'th object. As I have not implemented these earlier I was wondering if any of the two are good or are there better ways of getting things done. TIA, S

  • Do partitions allow multiple bulk loads?

    - by ck
    I have a database that contains data for many "clients". Currently, we insert tens of thousands of rows into multiple tables every so often using .Net SqlBulkCopy which causes the entire tables to be locked and inaccessible for the duration of the transaction. As most of our business processes rely upon accessing data for only one client at a time, we would like to be able to load data for one client, while updating data for another client. To make things more fun, all PKs, FKs and clustered indexes are on GUID columns (I am looking at changing this). I'm looking at adding the ClientID into all tables, then partitioning on this. Would this give me the functionality I require?

  • Getting back into C/C++ after several years

    - by themaninthesuitcase
    While at university I started my first programming with ANSI C, before we moved onto Java later in the course. Now I would like to go back to (re)learning C and C++ again to allow me to contribute with open source projects and also to expand my CV and improve my career prospects. Currently I mostly program in VB.net (I know I know, I try to not do things the nasty way you can with this) and am slowly picking up C# as I get some time at work. I also use a bit of java for Android dev. While I realise just doing it is the best way to learn, my exercise ideas are usually either trivial or beyond my current skills. What are some good sources for this initial relearn, I intend to possibly start helping with Chromium as other people seem to think this a good place to get started in OS. Basically any help getting back into this would be appreciated.

  • What is the correct way to customize Icon and Text position of items in a QListView?

    - by petermcg
    I'm using C++ and Qt's (4.6) model/view framework and wondering what is the correct way to change the display of items in a QListView or a class derived from QListView from: to: I'm not concerned about the sort order or Flow, I'm interested in the best way to correctly position the text to the right of the icon. If this can only be done by writing a custom QStyledItemDelegate that's totally fine, I want to rule out whether this is the correct approach or whether it's best to look at setLayout or similar, example code would help. The example application I'm looking at is the 'interview' example from qtdemo which amongst other things displays icons and text in a QListView.

  • minifying patched javascript files

    - by Stacia
    I'm writing a Rails app and I've partially integrated in this nice little patch to the in line ajax editor: http://inplacericheditor.box.re/ The problem is, on that page I have tinymce, prototype and scriptaculous included. In Firefox at least there's a big lag when all this stuff is loading. I was hoping to fix it by compressing the files so I checked out a plugin for rails called Smurf. It seemed to do what it was supposed to do nicely, but it choked on the little patch files that are included with the Ajax editor thing. THe patch files look like this: Object.extend(Ajax.InPlaceEditor.prototype, { handleAJAXFailure: function(transport) Alternatively, should I just be catching them instead of worrying about minfying them? I know I'm running on development and that Apache would maybe be handling serving the js files differently..It just seems like a lot of things to serve on one page.

  • Will an IO blocked process show 100% CPU utilization in 'top' output?

    - by Alex Stoddard
    I have an analysis that can be parallelized over a different number of processes. It is expected that things will be both IO and CPU intensive (very high throughput short-read DNA alignment if anyone is curious.) The system running this is a 48 core linux server. The question is how to determine the optimum number of processes such that total throughput is maximized. At some point the processes will presumably become IO bound such that adding more processes will be of no benefit and possibly detrimental. Can I tell from standard system monitoring tools when that point has been reached? Would the output of top (or maybe a different tool) enable me to distinguish between a IO bound and CPU bound process? I am suspicious that a process blocked on IO might still show 100% CPU utilization.

  • Django: how to pass form variable to simple tag in template

    - by Remigijus
    Hello. I am trying to do some custom things in Django comments form. I have simple tag named "get_flatpage_by_id" that returns flatpage model data as array. This is working I expected: {% get_flatpage_by_id 14 as page %} It's returning flatpage that ID is 14. But this is not working, if I try to pass {{ form.object_pk.data }} (that returns 14). This is how it should look like: {% get_flatpage_by_id form.object_pk.data as page %} Simple tag receives value "form.object_pk.data" (string), not 14. I don't know how to tell Django that "form.object_pk.data" is variable, not a string!

  • How to null a translation in in gettext system?

    - by Evgeny
    Suppose a simple phrase "In" in English needs to be interpreted as "" - empty string in Russian. Is is possible to specify that in the .po file? What normally happens if you set msgstr "" - you'll get the untranslated key, but I want to get nothing in that specific case. Here is a use case: I have underneath a search bar a set of buttons to select questions (for a Q&A site) from particular scopes - like so: (in English) In: [all] [unanswered] [my own] (in Russian I want) [???] [??? ???????] [???] It just sounds more natural. Yes I can leave out In for english, but I don't want to and I do not want to put button (things in [] are buttongs) html into the 'po' file. Thanks!

  • How to read, edit and write xls files, and then export to SQL Server

    - by tuanvt

So, I am writing an .net windows program using visual studio 2008 to read the files, generate random password for each contact, and then push these information in to my SQL Server database. It was easy to handle excel file in 2003 but now my computer have office 2007 in it and things seem to changed. I am digging on Microsoft.Office.Interop.Excel but it is seem to be a lot more complicated than before.

  • Defining a static array into a C or C++ source file.

    - by VansFannel
    Hello. I know this is a question that every programmer should know, but I do not know. Long time no C programming and I've forgotten a lot of things. My question is: I have three huge static arrays defined inside a header file. Someone told me that It's much better to declare them as extern in the header file, and define them in a single C or C++ source file. How can I do that? Here is my header file: #ifndef _TEMPLE_OBJECT_H_ #define _TEMPLE_OBJECT_H_ #define NUM_TEMPLE_OBJECT_VERTEX 10818 static const float TEMPLEVertices[NUM_TEMPLE_OBJECT_VERTEX * 3] = {...}; static const float TEMPLENormals[NUM_TEMPLE_OBJECT_VERTEX * 3] = {...}; static const float TEMPLETexCoords[NUM_TEMPLE_OBJECT_VERTEX * 3] = {...}; #endif If a use a C++ source file, may I need to define a class? Thank you.

  • Wait for animation, render to complete - XAML and C#

    - by Adam S
    Hi all. I have a situation where I am animating part of my XAML application, and I need to wait for the animation AND rendering to complete before I can move on in my code. So far the tail end of my function looks like: ProcExpandCollapse.Begin(); while (ProcExpandCollapse.GetCurrentState() != ClockState.Stopped) { } } Which, in theory, will wait until the animation is finished. But it will not wait until the rendering is finished - the thread drawing the application might still not have re-drawn the animation. The animation is expanding a UIElement, and then the next part of my code uses it's rendered size to do some things. My question then is, how do I wait until my UI Element is re-rendered before moving on?

  • Should repeated use of the camera crash an app?

    - by Sam
    I have an app that builds a slideshow from user images. They can grab from their library or take a picture. I have found that repeated use of grabbing an image from the library is fine. But repeated use of taking a picture causes erratic behavior. I have been getting crashes but mostly what happens seems to be a reloading of the view after "didFinishPickingMediaWithInfo", which messes things up. I have no leaks and it seems to be releasing properly after each picture is taken. I am resizing the image and saving it in a data base. Is anyone else running into this situation? Was the camera not designed to be called this often?

  • Cross vertion line matching.

    - by BCS
    I'm considering how to do automatic bug tracking and as part of that I'm wondering what is available to match source code line numbers (or more accurate numbers mapped from instruction pointers via something like addr2line) in one version of a program to the same line in another. (Assume everything is in some kind of source control and is available to my code) The simplest approach would be to use a diff tool/lib on the files and do some math on the line number spans, however this has some limitations: It doesn't handle cross file motion. It might not play well with lines that get changed It doesn't look at the information available in the intermediate versions. It provides no way to manually patch up lines when the diff tool gets things wrong. It's kinda clunky Before I start diving into developing something better: What already exists to do this? What features do similar system have that I've not thought of?

  • Is putting the javascript before the closing body tag okay on an asp.net website?

    - by Jason Weber
    I pretty much stated what I have to ask. But is taking all of your external .js files and putting them before the closing body tag on your master pages okay on an asp.net website? I'm just going off of what yslow and google speed have been showing. I can't combine these javascripts, so I'm trying to load them "after page load", but doing so makes them useless; some of my jquery things don't work. I moved my .js files above the opening body tag, and they work. What am I doing wrong? And what could I do to load my .js files after page load? Thanks for any advice anybody can offer!

  • What happens if an asynchronous delegate call never returns?

    - by RichardHowells
    I found a decent looking example of how to call a delegate asynchronously with a timeout... http://www.eggheadcafe.com/tutorials/aspnet/847c94bf-4b8d-4a66-9ae5-5b61f049019f/basics-make-any-method-c.aspx. In summary it uses WaitOne with a timeout to determine if the call does not return before the timeout expires. I also know that you should have an EndInvoke to match each BeginInvoke. So what happens if the wait timeout expires? We (presumably) DON'T want to call EndInvoke as that will block. The code can go on to do 'other things', but have we leaked anything? Is there some poor thread someplace blocked waiting for a return that's never going to happen? Have we leaked some memory where the result-that-will-never-return was going to be placed?
