  • How to best show progress info when using ADO.NET?

    - by Yadyn
    I want to show the user detailed progress information when performing potentially lengthy database operations. Specifically, when inserting/updating data that may be on the order of hundreds of KB or MB. Currently, I'm using in-memory DataTables and DataRows which are then synced with the database via TableAdapter.Update calls. This works fine and dandy, but the single call leaves little opportunity to glean any kind of progress info to show to the user. I have no idea how much data is passing through the network to the remote DB or its progress. Basically, all I know is when Update returns and it is assumed complete (barring any errors or exceptions). But this means all I can show is 0% and then a pause and then 100%. I can count the number of rows, even going so far to cound how many are actually Modified or Added, and I could even maybe calculate per DataRow its estimated size based on the datatype of each column, using sizeof for value types like int and checking length for things like strings or byte arrays. With that, I could probably determine, before updating, an estimated total transfer size, but I'm still stuck without any progress info once Update is called on the TableAdapter. Am I stuck just using an indeterminate progress bar or mouse waiting cursor? Would I need to radically change our data access layer to be able to hook into this kind of information? Even if I can't get it down to the precise KB transferred (like a web browser file download progress bar), could I at least know when each DataRow/DataTable finishes or something? How do you best show this kind of progress info using ADO.NET?

  • What is the best way to attach extenstion methods to static classes rather than to instances of a cl

    - by John Gietzen
    If I have a method for calculating the greatest common divisor of two integers as: public static int GCD(int a, int b) { return b == 0 ? a : GCD(b, a % b); } What would be the best way to attach that to the System.Math class? Here are the three ways I have come up with: public static int GCD(this int a, int b) { return b == 0 ? a : b.GCD(a % b); } // Lame... var gcd = a.GCD(b); and: public static class RationalMath { public static int GCD(int a, int b) { return b == 0 ? a : GCD(b, a % b); } } // Lame... var gcd = RationalMath.GCD(a, b); and: public static int GCD(this Type math, int a, int b) { return b == 0 ? a : typeof(Math).GCD(b, a % b); } // Neat? var gcd = typeof(Math).GCD(a, b); The desired syntax is Math.GCD since that is the standard for all mathematical functions. Any suggestions? What should I do to get the desired syntax?

  • What is the fastest and best way to convert an rmvb video to mp4/mkv without losing any quality?

    - by Eric Leung
    the file will be played in a popbox3d. my old method was to convert the video using vidcoder (an offshoot of handbrake) using normal settings, but i've recently confirmed that this significantly reduces video and audio quality. i bumped up the conversion quality to 'high profile' and this produced a higher quality video but raised the conversion time to about twice the video length (95 minutes to convert a 45 minute video) on a core2duo laptop. this is less than ideal when a large number of videos need to be converted. i have tried a direct remuxing using mkv toolnix but this produced a video that refused to display video on the popbox3d, which is consistent with the reported: [quote=other old thread] it is possible to put RealMedia A/V in MKV container (used MKVtoolnix) - however, it is awkward to play later. RV40 is only suspected to be based on H.264 - simplify, is not consistent with MPEG-4 AVC specification. [/quote] i have read that ... [quote=from old thread] Under normal circumstances, [ffmpeg] should convert the video to .video.mp4 and the audio to (.wav then to) .audio.mp4, then mux the video and audio into a new .mp4 file and delete the temporary video-only and audio-only files.[/quote] and i am currently attempting to discover how this is done. help? PS: i download a lot of series from asia and for some strange reason, rmvb is a really popular format over there. sometimes, it's the only format that's available. unfortunately, it's a format that is incompatible with the popbox3d, so i have to convert the files before i can watch them on my tv.

  • What are the best code-less website design sites available?

    - by Ken Pespisa
    I'm looking for an alternative to www.squarespace.com. Squarespace is great, but leans slightly toward the social networking industry. I'm looking for a simple way to build Web sites for small businesses. The criteria is the following: Requires no programming knowledge. No software to download - all design and maintenance can be done via browser Has a good selection of templates and layouts Essentially I'm looking for the features within Typepad.com or WordPress.com, but instead of focusing around a blog it would help build a more traditional Web site.

  • What's the best way to migrate SELECT applications and data from an old Mac to a one?

    - by jaydles
    I know I can make an easy transfer of everything using time machine, but I'm trying to transfer the minimum necessary to the new computer (applications I currently use, Aperture database, etc.) in order to keep the new machine as clean as possible, and avoid starting out with any legacy problems with permissions, etc. Clearly, I can copy individual apps and databases to an external drive and then install them on the new machine, but I'm trying to find an easier way.

  • What is the best testing pattern for checking that parameters are being used properly?

    - by Joseph
    I'm using Rhino Mocks to try to verify that when I call a certain method, that the method in turn will properly group items and then call another method. Something like this: //Arrange var bucketsOfFun = new BucketGame(); var balls = new List<IBall> { new Ball { Color = Color.Red }, new Ball { Color = Color.Blue }, new Ball { Color = Color.Yellow }, new Ball { Color = Color.Orange }, new Ball { Color = Color.Orange } }; //Act bucketsOfFun.HaveFunWithBucketsAndBalls(balls); //Assert ??? Here is where the trouble begins for me. My method is doing something like this: public void HaveFunWithBucketsAndBalls(IList<IBall> balls) { //group all the balls together according to color var blueBalls = GetBlueBalls(balls); var redBalls = GetRedBalls(balls); // you get the idea HaveFunWithABucketOfBalls(blueBalls); HaveFunWithABucketOfBalls(redBalls); // etc etc with all the different colors } public void HaveFunWithABucketOfBalls(IList<IBall> colorSpecificBalls) { //doing some stuff here that i don't care about //for the test i'm writing right now } What I want to assert is that each time I call HaveFunWithABucketOfBalls that I'm calling it with a group of 1 red ball, then 1 blue ball, then 1 yellow ball, then 2 orange balls. If I can assert that behavior then I can verify that the method is doing what I want it to do, which is grouping the balls properly. Any ideas of what the best testing pattern for this would be?

  • Best practice? Using DPM to backup VMs within each VM or through the host?

    - by andrew
    We've got two Hyper-V hosts running multiple VMs (all flavors of Windows Servers). One of the VMs is running MS Data Protection Manager 2010, which runs beautifully (most of the time) and is connected to a separate NAS via iSCSI for the DPM storage. I noticed when I installed the DPM agent on the Hyper-V hosts, it enumerates the VMs in the DPM Protection listing. I don't want to burn through my storage space too fast with duplicate protection, so I was wondering: Is it recommended to back up VMs through the host, or is it better to install the DPM agent on each VM and backup as I would any other machine? It would seem as though most people (currently including me) do it the second way, but is there any advantage to including the entries under HyperV (Backup using Child Partition Snapshop)?

  • What's the best external hard drive configuration for a software developer laptop?

    - by Dan
    I've got a Dell laptop that I use as a software developer box at work and find that the drive is usually the bottleneck. I'd like to hook up two 10k RPM drives that are striped for performance. I've looked for drive cases with RAID but there don't seem to be very many choices and I'm worried about compatibility with the drives (preferably SATA 2). Also I don't have a SATA connection on my machine so it'll have to USB 2.0 for now. Am I headed down the right path or am I missing a much simpler configuration?

  • What's the best solution for file sharing in my case? DAS or NAS?

    - by jakub
    I want to have in my network small, cheap and energy efficient server with will be fully customizable (Gnu/Linux, OpenBSD). What is more I want to have big, redundant storage in my network and access to it via server. I have already small terminal without hard drive (no SATA/PATA, one drive on USB) which works fine. I don't want to buy big server, or to use regular computer for that. It's not cheap. I thought about a small case (ITX?), and cheap computer in this with SATA ports, but I cannot find anything interesting :( I thought about NAS in network and server independently and booting server from NAS, I'm not sure which technologies will be good for that, and I don't know what with performance. Direct connection to NAS through network from workstation is next pro for that. What do you think about DAS? It will be good for that?

  • In PHP... best way to turn string representation of a folder structure into nested array

    - by Greg Frommer
    Hi everyone, I looked through the related questions for a similar question but I wasn't seeing quite what I need, pardon if this has already been answered already. In my database I have a list of records that I want represented to the user as files inside of a folder structure. So for each record I have a VARCHAR column called "FolderStructure" that I want to identify that records place in to the folder structure. The series of those flat FolderStructure string columns will create my tree structure with the folders being seperated by backslashes (naturally). I didn't want to add another table just to represent a folder structure... The 'file' name is stored in a separate column so that if the FolderStructure column is empty, the file is assumed to be at the root folder. What is the best way to turn a collection of these records into a series of HTML UL/LI tags... where each LI represents a file and each folder structure being an UL embedded inside it's parent?? So for example: file - folderStructure foo - bar - firstDir blue - firstDir/subdir would produce the following HTML: <ul> <li>foo</li> <ul> <li> bar </li> <ul> <li> blue </li> </ul> </ul> </ul> Thanks

  • Help: Best way to do a TV-out in 7300GT Nvidia video card?

    - by Martin Ongtangco
    I'm planning to recycle my old PC and build a Media Center using an open-source (C#) software called MediaPortal. My old PC has a GeForce 7300GT with a TV-out plug built-in. When I tested it last night, it wouldn't detect my JVC tv (CRT) using the current drivers. I even purchased a new copper-based TV-Out to RCA cable. I searched all 3 AV channels. The video card has 3 output ports: 2 DVI & 1 s-video. I used the s-video with a S-Video to RCA out cable. I swapped between PAL & NTSC So what I did was I downloaded the first version of an Nvidia driver for 7 series cards, but still even with the old console, it couldn't detect the TV. I'm running out of viable ideas. Anyone here had the same problem and fixed it? Any suggestion is appreciated. Thank you!

  • What's the best way I can import/display lyrics for iTunes on a mac?

    - by Jack Chu
    I'm currently using iClip Lyrics, but apparently it's being discontinued. It can't import lyrics from certain lyrics sites (such as wikia) because they've used some javascript/iframe mix to make copy/pasting difficult. I was wondering if there were other options that are better at importing lyrics automatically as well as displaying lyrics. Bonus points for solutions that handle unicode encoded characters too, since a good portion of my music library is asian.

  • 4.0/WCF: Best approach for bi-idirectional message bus?

    - by TomTom
    Just a technology update, now that .NET 4.0 is out. I write an application that communicates to the server through what is basically a message bus (instead of method calls). This is based on the internal architecture of the application (which is multi threaded, passing the messages around). There are a limited number of messages to go from the client to the server, quite a lot more from the server to the client. Most of those can be handled via a separate specialized mechanism, but at the end we talk of possibly 10-100 small messages per second going from the server to the client. The client is supposed to operate under "internet conditions". THis means possibly home end users behind standard NAT devices (i.e. typical DSL routers) - a firewalled secure and thus "open" network can not be assumed. I want to have as little latency and as little overhad for the communication as possible. What is the technologally best way to handle the message bus callback? I Have no problem regularly calling to the server for message delivery if something needs to be sent... ...but what are my options to handle the messagtes from the server to the client? WsDualHttp does work how? Especially under a NAT scenario? Just as a note: polling is most likely out - the main problem here is that I would have a significant overhead OR a significant delay, both aren ot really wanted. Technically I would love some sort of streaming appraoch, where the server can write messags to a stream while he generates them and they get sent to the client as they come. Not esure this is doable with WCF, though (if not, I may acutally decide to handle the whole message part outside of WCF and just do control / login / setup / destruction via WCF).

  • What's the best practice to add default function to jQuery Dialog open/close events?

    - by BlueFox
    Hi All, I'm trying to define some default behaviours for my jQuery Dialogs like the following: (function($) { /** * Overriding default options **/ $.ui.dialog.defaults.bgiframe = true; $.ui.dialog.defaults.open = function() { if ($('.ui-widget-overlay').length == 0) return; if ($.browser.msie) { // scrollbar fix for IE $('html').css('overflow-y','hidden'); $('html').css('overflow-x','hidden'); } else { // disable scrollbar for other browsers $('body').css('overflow','hidden'); } }; $.ui.dialog.defaults.beforeclose = function(event, ui) { if ($('.ui-widget-overlay').length == 0) return; if ($.browser.msie) { // scrollbar fix for IE $('html').css('overflow-y','auto'); $('html').css('overflow-x','auto'); } else { // disable scrollbar for other browsers $('body').css('overflow','auto'); } }; })(jQuery); The above works when I have no custom open/beforeclose function specified when the dialog is created. So I'm wondering what is the best practice to add these functionality into all my dialogs, while preserving the ability to specify open/beforeclose functions.
