  • How to convert DateTime to a number with a precision greater than days in T-SQL?

    - by Jader Dias
    Both queries below translates to the same number SELECT CONVERT(bigint,CONVERT(datetime,'2009-06-15 15:00:00')) SELECT CAST(CONVERT(datetime,'2009-06-15 23:01:00') as bigint) Result 39978 39978 The generated number will be different only if the days are different. There is any way to convert the DateTime to a more precise number, as we do in .NET with the .Ticks property? I need at least a minute precision.

  • Recommendations for a free GIS library supporting raster images

    - by gspr
    Hi. I'm quite new to the whole field of GIS, and I'm about to make a small program that essentially overlays GPS tracks on a map together with some other annotations. I primarily need to allow scanned (thus raster) maps (although it would be nice to support proper map formats and something like OpenStreetmap in the long run). My first exploratory program uses Qt's graphics view framework and overlays the GPS points by simply projecting them onto the tangent plane to the WGS84 ellipsoid at a calibration point. This gives half-decent accuracy, and actually looks good. But then I started wondering. To get the accuracy I need (i.e. remove the "half" in "half-decent"), I have to correct for the map projection. While the math is not a problem in itself, supporting many map projection feels like needless work. Even though a few projections would probably be enough, I started thinking about just using something like the PROJ.4 library to do my projections. But then, why not take it all the way? Perhaps I might aswell use a full-blown map library such as Mapnik (edit: Quantum GIS also looks very nice), which will probably pay off when I start to want even more fancy annotations or some other symptom of featuritis. So, finally, to the question: What would you do? Would you use a full-blown map library? If so, which one? Again, it's important that it supports using (and zooming in and out with) raster maps and has pretty overlay features. Or would you just keep it simple, and go with Qt's own graphics view framework together with something like PROJ.4 to handle the map projections? I appreciate any feedback! Some technicalities: I'm writing in C++ with a Qt-based GUI, so I'd prefer something that plays relatively nicely with those. Also, the library must be free software (as in FOSS), and at least decently cross-platform (GNU/Linux, Windows and Mac, at least). Edit: OK, it seems I didn't do quite enough research before asking this question. Both Quantum GIS and Mapnik seem very well suited for my purpose. The former especially so since it's based on Qt.

  • How does one retrieve the email address of a user with GData?

    - by sblom
    I'm trying to use GData to retrieve the email address, real name, and profile URL of the user that just authorized my site using Google OAuth. We know how to request it using Google's OpenID flow, but the OpenID flow has the severe limitation that we have to ask for a Google Apps user's domain before we know where to send them to log in. At least using OAuth (or even AuthSub), the user gets prompted for which of their Google accounts to log in.

  • If tables are so evil, why does joomla use tables for its layout?

    - by DMin
    When you create a template you don't use tables. but when joomla rendereds the page, there are at least 4 places where tables are used to structure the content. Does this tell you something about tables or the fact that the joomla community should invest more time and learn how to code css or just the fact that tables are needed when you don't know what css is going to be throw in later(which probably means they are of some use)?

  • Java constructor with large arguments or Java bean getter/setter approach

    - by deelo55
    Hi, I can't decide which approach is better for creating objects with a large number of fields (10+) (all mandatory) the constructor approach of the getter/setter. Constructor at least you enforce that all the fields are set. Java Beans easier to see which variables are being set instead of a huge list. The builder pattern DOES NOT seem suitable here as all the fields are mandatory and the builder requires you put all mandatory parameters in the builder constructor. Thanks, D

  • Google Maps on IPhone won't zoom

    - by Rob Bonner
    Hello, I have an iPhone app that loads the following URL: http://maps.google.com?q=Apple Stores&ll=37.331689,-122.030731&z=3 As expected, the google maps app loads on the phone, but zooms to the entire US. It does not appear to be respecting the z= parameter, or at least, not allowing a zoom level that shows stores in the area.

  • Silverlight 3 oob window border

    I was wondering if I can customise the look and feel of the OOB window of my SL app? I want it to look different than the standard windows frame (maybe at least change the visible buttons like minimise or maximise...) thanks

  • jQuery table filter with text, checkboxes, selects

    - by Jeffrey
    Need to filter a table from outside of the table, with a text search, checkboxes, and selects. PicNet Table Filter for jQuery works for both searching and using checkboxes outside of the table... though I can't find any examples of how to get a select box to work. Anyone know? *I might be getting too specific here, but thought I'd at least inquire. I'm also open to possibilities other than PicNet.

  • DCVS + hosting for a startup commercial multiplatform phone app

    - by AG
    I'm in lean startup mode, working on a simple phone app that will be published initially as a iThingy app and an Android app with, possibly, Blackberry and Symbian versions to follow. I'm about to go from no repository to needing a central repository that up to 4 very part-time resources will be sharing. Two of us have no version control background, one has used Subversion, and I've used most of the major centralized VCS systems. I'm not going to be pushing the technical limitations of any VCS for a long time; I'm sure that any of the major systems would work fine. And the hosting accounts I've looked at seem reasonable. So I'm really focussed on minimizing the downside risks. That is, I'd like to find a stable setup that is easy to learn in general, easy to use from Windows/Eclipse, and won't paint me into any obvious corners for the next 12 months or so. A quick search of the web had led me to consider the following pairs of DVCS and hosting service, with what I think I'm hearing as their strengths and weaknesses (for my purposes): Bazaar/Launchpad -- My initial choice since I need to get more familiar with this pair for the Google Summer of Code mentoring I'm doing. But, whatever the technical merits, a non-starter for me because they are purely open source, no private repositories plans to purchase that I can see. Git/GitHub -- Git: Fast, light, ultimately flexible, but relatively less Windows friendly, Eclipse plugin (eGit) available but relatively young, GitHub: widely used, pricing is fine Mercurial/BitBucket -- Mercurial: a little less flexible, a little more Windows friendly, Eclipse plugin seems a bit more mature, BitBucket: widely used, pricing is fine, includes a wiki and an issue tracker that we might be able to use instead of something like BaseCamp, at least for a while. Mercurial/BitBucket seem like the winning pair so far for my particular situation; at least two of us are definitely going to be working mostly from Eclipse on Windows and reducing my own learning curve is a priority. ;-) But I have two specific questions: 1) Am I wrong about Bazaar/Launchpad and is there a viable, secure way to use them for proprietary code? 2) Any reason to think that the Mecurial/Bitbucket pair will end up being a headache for my Mac developer, soon, or for Blackberry or Symbian developers a little later? ag

  • MS Runtime required for app to run, how can I include with setup?

    - by JPJedi
    My application requires access to be installed on the computer or at least the MS Access runtime. Is their a way to include that with the application to check for that component/resource or install it if it isn't? Or would it just be easier to include a link to tell the user where to get the runtime if the error happens? I am using Visual Studio 2008 and the windows form app is written in VB.net. I am currently using click once for the deployment. Thanks

  • is it possible to tell if DOM was modified, and which part?

    - by mkoryak
    Are there any practical ways to tell what part of the DOM was modified if you know that it will be modified? I am writing a plugin that will be running along with javascript that i did not write. an event will be triggered before DOM is modified, and one event will be triggered after the modification. It is my job to decide what was changed. is this possible, and if so what is the least horrible way to do this?

  • Is there any boost-independent version of boost/tr1 shared_ptr

    - by Artyom
    I'm looking for independent implementation of boost/tr1 shared_ptr, weak_ptr and enable_shared_from_this. I need: Boost independent very small implementation of these features. I need support of only modern compilers like GCC-4.x, MSVC-2008, Intel not things like MSVC6 or gcc-3.3 I need it to be licensed under non-copyleft LGPL compatible license like Boost/Mit/3-clause BSD. So I can include it in my library. Note - it is quite hard to extract shared_ptr from boost, at least BCP gives about 324 files...

  • Is there any reason for an object pool to not be treated as a singleton?

    - by Chris Charabaruk
    I don't necessarily mean implemented using the singleton pattern, but rather, only having and using one instance of a pool. I don't like the idea of having just one pool (or one per pooled type). However, I can't really come up with any concrete situations where there's an advantage to multiple pools for mutable types, at least not any where a single pool can function just as well. What advantages are there to having multiple pools over a singleton pool?

  • Determine if method is unsafe via reflection

    - by hmemcpy
    I'm looking for a way to filter out methods which have the unsafe modifier via reflection. It doesn't seem to be a method attribute. Is there a way? EDIT: it seems that this info is not in the metadata, at least I can't see it in the IL. However reflector shows the unsafe modifier in C# view. Any ideas on how it's done? Thanks!

  • scripting fruityloops or propellerheads reason from VB or Python?

    - by interstar
    I have both Fruityloops and Propellerheads Reason software synths on my Windows PC. Any way I can get at and script these from either Visual Basic or Python? Or at least send Midi messages to the synths from code? Update : attempts to use something like a "midi-mapper" (thanks for link MusiGenesis) don't seem to work. I don't think Reason or FL Studio act like standard GM Midi synths. Update 2 : If you're interested in this question, check out this too.

  • packaging and distributing Python code as executables

    - by user248237
    How can I compile my python module into an executable, and distribute it in a way that doesn't require the user to download all the external Python packages that the module I wrote uses? Aside from that, is there a general guy on packaging and distributing python code? i.e. going from a script/module to someone that's user-friendly and can be run, ideally cross-platform (at least between unix and mac). thanks.
