  • Formatting the code en-masse in Visual Studio

    - by AngryHacker
    I've inherited a project where all the private variables, and there are thousands, are separated by a blank line. For instance, private pnlSecurityReport _pnlSecurityReport = null; private pnlCalendar _pnlCalendar = null; private CtlContacts _pnlContacts = null; private pnlEmails _pnlEmails = null; private CtlNotes _pnlNotes = null; private pnlRoles _pnlRoles = null; private pnlSecurity _pnlSecurity = null; private pnlSignatures _pnlSignatures = null; This is really annoying. I'd like to remove the blank lines. Beyond writing my own tool to seek out and remove the extra line, is there a way to do this, perhaps, using RegEx-Fu in the Search and Replace dialog?

  • playing only part of a sound using FMOD

    - by carneades
    I'm trying to play only part of a sound using FMOD, say frames 50000-100000 of a 200000 frame file. I have found a couple of ways to seek forward (i.e. to start playback at frame 50000) but I have not found a way to make sure the sound stops playing at 100000. Is there any way FMOD can natively do this without having to add lbsndfile or the like into the picture? I should also mention that I am using the streaming option. I have to assume that these sounds are arbitrarily large and cannot be comfortably/quickly loaded into memory.

  • How to filter a dataview

    - by dboarman-FissureStudios
    I have a dataview that contains a list of tables. I am reading in a list of values that I then want to apply as a filter to this dataview. The list of values is actually in the form of "table1, table2, table3". So I thought I would be able to use this as a filter on my dataview. SqlOp.CommandText = "select name from dbo.sysobjects where xtype='u'"; SqlOp.ExecuteDataReader(); DataView dv = SqlOp.GetDataAsDataView(); SqlOp.CloseConnection(); Returns a list of all the tables in a dataview. Any help on how to filter this dataview? Edit: Not sure if I was completely clear in what I seek to accomplish. To clarify, I am trying to figure out how/if .RowFilter will help me in filtering this dataview. Something like: dv.RowFilter = "name IN (table1, table2, table3)" // I know this doesn't work

  • HTML 5 video custom controls

    - by pygorex1
    Like many web developers I'm looking forward to streaming video that utilizes the new HTML 5 <video> tag. Browser support definitely isn't wide enough yet, so using a Flash/SWF fallback is a must. This got me thinking: in Flash it's possible to highly customize the playback controls (pause, play, stop, seek, volume, etc.) in HTML 5?. What options are there for customizing the glyphs, icons and colors of video controls? Is Javascript required? For instance the following page renders different controls depending on the browser - tested using FF3.5, Chrome and Safari: http://henriksjokvist.net/examples/html5-video/ It would be really awesome to customize and standardize controls across browsers and even match the Flash controls used by older browsers.

  • jList in Scrollpane, seeking and displaying value of selectedIndex

    - by Mech Software
    I have a JList inside a Scrollpane. If you click on the list and move the arrow keys up and down it works like you expect, you can move your selection index and display around just fine. Now, what I want to do is basically have a text box and i'm typing in the text box like "comic" and want it to seek to the index of that value. This WORKS just fine. Where the problem is when the value of the list box is below, or above the viewable area. When it is, the selected index seeks, but does not change the position of the scrollable region. However, if I press the up or down arrows and requestFocus() to the list, and move up and down it seeks to the right viewable area. What am I missing to make this happen WITHOUT changing focus. I want to be able to just type in the list all I want and have it show me what is selected. I feel i'm missing something obvious here.

  • High PageIOLatch_SH Waits with High Drive Idle times

    - by Marty Trenouth
    We are experiencing high volume of PageIOLatch_SH waits on our database (row counts in the Billions). However it seems that our drive Idle time Percentage hovers around 50-60 percent. CPU usage is nill. The Database Tuning Advisor gives no suggestions for optimization. The query plan (actual) from the single stored procedure used on the database puts the majority of the expense on index seek (yeah I know these should be optimial) operations. Anyone have suggestions of how to increase throughput?

  • BinaryFormatter with MemoryStream Question

    - by Changeling
    I am testing BinaryFormatter to see how it will work for me and I have a simple question: When using it with the string HELLO, and I convert the MemoryStream to an array, it gives me 29 dimensions, with five of them being the actual data towards the end of the dimensions: BinaryFormatter bf = new BinaryFormatter(); MemoryStream ms = new MemoryStream(); byte[] bytes; string originalData = "HELLO"; bf.Serialize(ms, originalData); ms.Seek(0, 0); bytes = ms.ToArray(); returns - bytes {Dimensions:[29]} byte[] [0] 0 byte [1] 1 byte [2] 0 byte [3] 0 byte [4] 0 byte [5] 255 byte [6] 255 byte [7] 255 byte [8] 255 byte [9] 1 byte [10] 0 byte [11] 0 byte [12] 0 byte [13] 0 byte [14] 0 byte [15] 0 byte [16] 0 byte [17] 6 byte [18] 1 byte [19] 0 byte [20] 0 byte [21] 0 byte [22] 5 byte [23] 72 byte [24] 69 byte [25] 76 byte [26] 76 byte [27] 79 byte [28] 11 byte Is there a way to only return the data encoded as bytes without all the extraneous information?

  • LNK1106 with big binary resource

    - by E Dominique
    I have a rather huge .dat-file (896MB) included as a BIN resource in my project. Now I get a LNK1106 link error ("fatal error LNK1106: invalid file or disk full: cannot seek to 0x382A3920".) I use Visual Studio 2005 under Windows XP, and have tried on a 4GB RAM machine with high Virtual Memory settings and lots of disk space. I have tried a number of different optimization flags, but to no avail. Does anyone have a clue? EDIT: I have narrowed it down to a specific size of the compiled resource. If the .res file is 544078588 bytes (about 518.9MB) or larger, the error occurs. If it is smaller it works just fine. Still no solution, though...

  • pycurl script can't login to website

    - by The Jug
    I'm currently trying to get a grasp on pycurl. I'm attempting to login to my own website. After logging into the site it should redirect to the main page. However when trying this script it just gets returned to the login page. What might I be doing wrong? import pycurl import urllib import StringIO import pycurl pf = {'username' : 'user', 'password' : 'pass' } fields = urllib.urlencode(pf) pageContents = StringIO.StringIO() p = pycurl.Curl() p.setopt(pycurl.FOLLOWLOCATION, 1) p.setopt(pycurl.COOKIEFILE, './cookie_test.txt') p.setopt(pycurl.COOKIEJAR, './cookie_test.txt') p.setopt(pycurl.POST, 1) p.setopt(pycurl.POSTFIELDS, fields) p.setopt(pycurl.WRITEFUNCTION, pageContents.write) p.setopt(pycurl.URL, 'http://localhost') p.perform() pageContents.seek(0) print pageContents.readlines()

  • Implementing a Stack using Test-Driven Development

    - by devoured elysium
    I am doing my first steps with TDD. The problem is (as probably with everyone starting with TDD), I never know very well what kind of unit tests to do when I start working in my projects. Let's assume I want to write a Stack class with the following methods(I choose it as it's an easy example): Stack<T> - Push(element : T) - Pop() : T - Seek() : T - Count : int - IsEmpty : boolean How would you approch this? I never understood if the idea is to test a few corner cases for each method of the Stack class or start by doing a few "use cases" with the class, like adding 10 elements and removing them. What is the idea? To make code that uses the Stack as close as possible to what I'll use in my real code? Or just make simple "add one element" unit tests where I test if IsEmpty and Count were changed by adding that element? How am I supposed to start with this?

  • Iphone progressive download audio player

    - by joynes
    Hi! Im trying to implement a progressive download audio player for the iphone, ie using http and fixed size mp3-files. I found the AudioStreamer project but it seems very complicated and works best with endless streams. I need to be able to find out the total length of audiofiles and I also need to be able to seek in the files. I found a hacked deviation from AudioStreamer but it doesnt seem to work very well for me. http://www.saygoodnight.com/?p=14 Im wondering if there is a more simple way to achieve my goals or if there are some better working samples out there? I found the bass library but not much documentation about it. /Br Johannes

  • BlackBerry - video player - FramePositioningControl is null

    - by sinu-mathews
    I'm developing a blackberry application that plays video from the server. I've used Player.start() and Player.stop() for playing and pausing a video. But I also need rewind, forward and seek bar controls in my application. I tried using FramePositioningControl for these controls. But the following code is returning null. FramePositioningControl framePositioningControl = (FramePositioningControl) player.getControl("FramePositioningControl"); I searched several forums and they say many players do not support FramePositioningControl. What players support FramePositioningControl? And what else should I do to add these controls in my application?

  • Managing string resources in a Java application - singleton?

    - by Joe Attardi
    I seek a solution to the age-old problem of managing string resources. My current implementation seems to work well, but it depends on using singletons, and I know how often singletons can be maligned. The resource manager class has a singleton instance that handles lookups in the ResourceBundle, and you use it like so: MessageResources mr = MessageResources.getMessageResources(); // returns singleton instance ... JLabel helloLabel = new JLabel(mr.getString("label.hello")); Is this an appropriate use of a singleton? Is there some better, more universally used approach that I'm not aware of? I understand that this is probably a bit subjective, but any feedback I can get would be appreciated. I'd rather find out early on that I'm doing it wrong than later on in the process. Thanks!

  • Best practices to build a highly configurable software product.

    - by Kabeer
    Hello. I am working on a software product that can substantially change behavior based on the configuration & meta-data supplied. I would like to know best practices to architect / build a highly configurable software product. Considering that there are substantial number of configuration parameters, I'd like to look at something that will not affect the performance before I look at dependency injection. My platform is .Net ... I seek recommendations on architecture / design and implementations fronts.

  • AVAudioPlayer currentTime problem

    - by StrAbZ
    Hi, I'm trying to use the audioplayer with a slider in order to seek into a track (nothing complicated). But I have a weird behavior... for some value of currentTime (between 0 and trackDuration), the player stop playing the track, and goes into "audioPlayerDidFinishPlaying:successfully:" with successfully to NO. And it did not go into "audioPlayerDecodeErrorDidOccur:error:" It's like it can't read the time i'm giving to it. For exemple the duration of the track is: 295.784424 seconds i set the currentTime to 55.0s (ie: 54.963878 or 54.963900 or 54.987755, etc... when printed as %f). The "crashes" always happen when the currentTime is 54.987755... and I really don't understand why... So if you have any idea... ^^

  • Seeking through a streamed MP3 file with HTML5 <audio> tag

    - by Kyle Slattery
    Hopefully someone can help me out with this. I'm playing around with a node.js server that streams audio to a client, and I want to create an HTML5 player. Right now, I'm streaming the code from node using chunked encoding, and if you go directly to the URL, it works great. What I'd like to do is embed this using the HTML5 <audio> tag, like so: <audio src="http://server/stream?file=123"> where /stream is the endpoint for the node server to stream the MP3. The HTML5 player loads fine in Safari and Chrome, but it doesn't allow me to seek, and Safari even says it's a "Live Broadcast". In the headers of /stream, I include the file size and file type, and the response gets ended properly. Any thoughts on how I could get around this? I certainly could just send the whole file at once, but then the player would wait until the whole thing is downloaded--I'd rather stream it.

  • How can I determine if there is an open source software for a specific purpose?

    - by afsharm
    Hi, We are going to write an entire new application for a reservation system. In this system experts specify their free time in elaborated calendar and users seek them through searched and finally reserve the expert and his time. We prefer to find an open source program like this and try to evolve it instead of creating it from scratch. In this manner our time is saved and that open source program will be completer too. We are a entire .NET (ASP.NET, C#, NHibernate) company. We have same problem to find open source applications for our new projects. Any help is highly appreciated.

  • Why would a error get thrown inside my try-catch?

    - by George Johnston
    I'm pushing a copy of our application over to a new dev server (IIS7) and the application is blowing up on a line inside of a try-catch block. It doesn't happen locally, it actually obey's the rules of a try-catch block, go figure. Any idea why this would be happening? Shouldn't it just be failing silently? Is there something environmental I need to enable/disable? Exception Details: System.NullReferenceException: Object reference not set to an instance of an object. Line 229: Try Line 230: Here >> : _MemoryStream.Seek(6 * StartOffset, 0) Line 232: _MemoryStream.Read(_Buffer, 0, 6) Line 233: Catch ex As IOException End Try Although it doesn't matter for answering this question, I thought I would mention that it's third party code for the Geo IP lookup.

  • Access MP3 audio data independently of ID3 tags?

    - by kyl191
    Hi, this is a 2 part question. First off, is it possible to access the audio data in an MP3 independently of the ID3 tags, and secondly, is there any way to do so using available libraries? I recently consolidated my music collection from 3 computers and ended up with songs which had changed ID3 tags, but the audio data itself was unmodified. Running a search for duplicate files failed because the file changed with the ID3 tag change, but I think it should be possible to identify duplicate files if I just run a deduplication using the audio data for comparison. I know that it's possible to seek to a particular position past the ID3 header in the file, and directly read the data, but was wondering if there's a library that would expose the audio data so I could just extract the data, run a checksum on it, and store the computed result somewhere, then look for identical checksums. (Also, I'd probably have to use some kind of library when you take into account variable length headers.)

  • How to render the properties of the view model's base class first when using ViewData.ModelMetadata.

    - by Martin R-L
    When I use the ViewData.ModelMetadata.Properties in order to loop the properties (with an additional Where(modelMetadata => modelMetadata.ShowForEdit && !ViewData.TemplateInfo.Visited(modelMetadata))), and thereby create a generic edit view, the properties of the view model's base class are rendered last. Is it possible to use a clever OrderBy() or is there another way to first get the properties of the base class, and then the sub class'? Reverse won't do the trick since the ordering of each class' properties is perfectly fine. A workaround would of course be composition + delegation, but since we don't have mixins, it's too un-DRY IMHO, why I seek a better solution if possible.

  • Database query optimization

    - by hdx
    Ok my Giant friends once again I seek a little space in your shoulders :P Here is the issue, I have a python script that is fixing some database issues but it is taking way too long, the main update statement is this: cursor.execute("UPDATE jiveuser SET username = '%s' WHERE userid = %d" % (newName,userId)) That is getting called about 9500 times with different newName and userid pairs... Any suggestions on how to speed up the process? Maybe somehow a way where I can do all updates with just one query? Any help will be much appreciated! PS: Postgres is the db being used.

  • mmap() for large file I/O?

    - by Boatzart
    I'm creating a utility in C++ to be run on Linux which can convert videos to a proprietary format. The video frames are very large (up to 16 megapixels), and we need to be able to seek directly to exact frame numbers, so our file format uses libz to compress each frame individually, and append the compressed data onto a file. Once all frames are finished being written, a journal which includes meta data for each frame (including their file offsets and sizes) is written to the end of the file. I'm currently using ifstream and ofstream to do the file i/o, but I am looking to optimize as much as possible. I've heard that mmap() can increase performance in a lot of cases, and I'm wondering if mine is one of them. Our files will be in the tens to hundreds of gigabytes, and although writing will always be done sequentially, random access reads should be done in constant time. Any thoughts as to whether I should investigate this further, and if so does anyone have any tips for things to look out for? Thanks!

  • AVPlayer seeking to a different point after app resume

    - by CGuess
    I have an AVPlayer, the video in it is ~2 seconds long. After the video plays, if the app goes to the background and reenters the foreground I need the video to still be shown exactly as it was when the app was exited. The AVPlayer sticks around just fine, however when I reenter the app from the background the video appears to be seeked to the middle of the video. However, if I just play the video, it starts from the beginning, so it doesn't seem like it actually seeked and is just showing a preview image. I've tried to auto-seek the video to the end on relaunch but nothing happens . Nothing I can figure out or find in the docs would describe this behavior. Any tips on having the video launch either at the beginning or end?

  • Flex 3: Embedding MovieClip Symbol to Image Control programmatically

    - by BlueDude
    I've reviewed all the documentation and Google results surrounding this and I think I have everything setup correctly. My problem is that the symbol is not appearing in my app. I have a MovieClip symbol that I've embedded to my Flex Component. I need to create a new Image control for each item from my dataProvider and assign this embedded symbol as the Image's source. I thought it was simple but apparently not. Here's a stub of the code: [Embed(source="../assets/assetLib.swf", symbol="StarMC")] private var StarClass:Class; protected function rebuildChildren():void { iterator.seek( CursorBookmark.FIRST ); while ( !iterator.afterLast ) { child = new Image(); var asset:MovieClipAsset = new StarClass() as MovieClipAsset; (child as Image).source = asset; } } I know the child is being created because I can draw a shape and and that appears. Am I doing something wrong? Thank you!

  • CMS common Architecture

    - by Shalan
    Hi there, I know this is a weird question to ask, but I would like to know if there is any documentation/blog-article out there that explains the architecture of a Website content management system? More particularly, I am interested to learn more about how "widgets" are implemented. I can't remember which system it was that I've seen tis one, but in the "Page Layout view" it had the ability to allow the end user to select a widget (thumbnail gallery, contact form, etc) from a list, and drag and drop it onto custom areas of the page. I know that this is not directly a programming question, but please could I seek advice/feedback on this. Thanks!
