  • Windows Service Setup issue removing the windows service

    - by Geykel
    I'm doing a windows service setup project on VS2008, it has a custom action for setting app.config values. The setup work fine installing the service and setting the app.config values but when I try to uninstall the service, it removes the files but keep the service registered, so I can install it again using the setup, I need to use "sc delete " in the vs command prompt to proper remove the service... anyone have any idea which could be the issue here? Thank you.

  • Can I use UIRefreshControl with UICollectionViewScrollDirectionHorizontal?

    - by Dan Abramov
    You can add UIRefreshControl to UICollectionView (or any UIScrollView for that matter) by adding it to collection's subviews: UIRefreshControl *refreshControl = [[UIRefreshControl alloc] init]; [refreshControl addTarget:self action:@selector(handleRefresh:) forControlEvents:UIControlEventValueChanged]; [self.collectionView addSubview:refreshControl]; This doesn't work when collection view layout has UICollectionViewScrollDirectionHorizontal. I tried overriding layoutSubviews to put refresh control to the left, but it wouldn't track scrolling progress this way. Can I trick it into working with horizontal layouts?

  • Samplegrabber works fine on AVI/MPEG files but choppy with WMV

    - by jomtois
    I have been using the latest version of the WPFMediaKit. What I am trying to do is write a sample application that will use the Samplegrabber to capture the video frames of video files so I can have them as individual Bitmaps. So far, I have had good luck with the following code when constructing and rendering my graph. However, when I use this code to play back a .wmv video file, when the samplegrabber is attached, it will play back jumpy or choppy. If I comment out the line where I add the samplegrabber filter, it works fine. Again, it works with the samplegrabber correctly with AVI/MPEG, etc. protected virtual void OpenSource() { FrameCount = 0; /* Make sure we clean up any remaining mess */ FreeResources(); if (m_sourceUri == null) return; string fileSource = m_sourceUri.OriginalString; if (string.IsNullOrEmpty(fileSource)) return; try { /* Creates the GraphBuilder COM object */ m_graph = new FilterGraphNoThread() as IGraphBuilder; if (m_graph == null) throw new Exception("Could not create a graph"); /* Add our prefered audio renderer */ InsertAudioRenderer(AudioRenderer); var filterGraph = m_graph as IFilterGraph2; if (filterGraph == null) throw new Exception("Could not QueryInterface for the IFilterGraph2"); IBaseFilter renderer = CreateVideoMixingRenderer9(m_graph, 1); IBaseFilter sourceFilter; /* Have DirectShow find the correct source filter for the Uri */ var hr = filterGraph.AddSourceFilter(fileSource, fileSource, out sourceFilter); DsError.ThrowExceptionForHR(hr); /* We will want to enum all the pins on the source filter */ IEnumPins pinEnum; hr = sourceFilter.EnumPins(out pinEnum); DsError.ThrowExceptionForHR(hr); IntPtr fetched = IntPtr.Zero; IPin[] pins = { null }; /* Counter for how many pins successfully rendered */ int pinsRendered = 0; m_sampleGrabber = (ISampleGrabber)new SampleGrabber(); SetupSampleGrabber(m_sampleGrabber); hr = m_graph.AddFilter(m_sampleGrabber as IBaseFilter, "SampleGrabber"); DsError.ThrowExceptionForHR(hr); /* Loop over each pin of the source filter */ while (pinEnum.Next(pins.Length, pins, fetched) == 0) { if (filterGraph.RenderEx(pins[0], AMRenderExFlags.RenderToExistingRenderers, IntPtr.Zero) >= 0) pinsRendered++; Marshal.ReleaseComObject(pins[0]); } Marshal.ReleaseComObject(pinEnum); Marshal.ReleaseComObject(sourceFilter); if (pinsRendered == 0) throw new Exception("Could not render any streams from the source Uri"); /* Configure the graph in the base class */ SetupFilterGraph(m_graph); HasVideo = true; /* Sets the NaturalVideoWidth/Height */ //SetNativePixelSizes(renderer); } catch (Exception ex) { /* This exection will happen usually if the media does * not exist or could not open due to not having the * proper filters installed */ FreeResources(); /* Fire our failed event */ InvokeMediaFailed(new MediaFailedEventArgs(ex.Message, ex)); } InvokeMediaOpened(); } And: private void SetupSampleGrabber(ISampleGrabber sampleGrabber) { FrameCount = 0; var mediaType = new AMMediaType { majorType = MediaType.Video, subType = MediaSubType.RGB24, formatType = FormatType.VideoInfo }; int hr = sampleGrabber.SetMediaType(mediaType); DsUtils.FreeAMMediaType(mediaType); DsError.ThrowExceptionForHR(hr); hr = sampleGrabber.SetCallback(this, 0); DsError.ThrowExceptionForHR(hr); } I have read a few things saying the the .wmv or .asf formats are asynchronous or something. I have attempted inserting a WMAsfReader to decode which works, but once it goes to the VMR9 it gives the same behavior. Also, I have gotten it to work correctly when I comment out the IBaseFilter renderer = CreateVideoMixingRenderer9(m_graph, 1); line and have filterGraph.Render(pins[0]); -- the only drawback is that now it renders in an Activemovie widow of its own instead of my control, however the samplegrabber functions correctly and without any skipping. So I am thinking the bug is in the VMR9 / samplegrabbing somewhere. Any help? I am new to this.

  • Parsing HTML using HtmlParser

    - by Blankman
    My html has 20 or so rows of the following HTML pattern. So the below is considered a single instance of the pattern. Each instance of this pattern represents a product. Again the below is a single instance, it spans multiple rows in the HTML table. <table> .. <!-- product starts here, this html comment is not in the real html --> <tr> <td rowspan="5" class="product" valign="top"><nobr> ????????????</td> </tr> <tr> <td class="title" ??????????>?????????</td> <td class="title" ??????????>?????????</td> <td class="title" ??????????>?????????</td> <td class="title" ??????????>?????????</td> <td class="title" ??????????>?????????</td> <td class="title" ??????????>?????????</td> </tr> <tr> <td class="data" ?????? </td> <td class="data" ?????? </td> <td class="data" ?????? </td> <td class="data" ?????? </td> <td class="data" ?????? </td> <td class="data" ?????? </td> </tr> </tr> <tr> <td colspan="5" ????????</td> </tr> <tr> <td colspan="6" width="100%">&nbsp;<hr></td> </tr> <!-- product ends here, this html comment is not in the real html --> <!-- above pattern repeats multiple times in the HTML --> .. <table> I am trying to use HtmlParser for this. Parser rowParser = new Parser(); rowParser.setInputHtml(page.getHtml()); // page object represents a html page rowParser.setEncoding("UTF-8"); NodeFilter productRowFilter = new AndFilter( new TagNameFilter("tr"), new HasChildFilter( new AndFilter( new TagNameFilter("td"), new HasAttributeFilter("class", "product"))) The above filter doesn't work, just showing you what I have so far. I need to somehow combine these filters, and use the last td to mark the end of the pattern i.e. the td with the colspan=6 and width=100% with child element hr. I have been struggling with this, and have resorted to Regex'ing but was told numerous times to NOT use regex for html parsing, so here I am! Your help is much appreciated!

  • Windows Scheduler OR SQL Server Job for sending out digest e-mails

    - by wgpubs
    Will be sending out e-mails from an application on a scheduled basis. I have an EmailController in my ASP.NET MVC application with action methods, one for each kind of notification/e-mail, that will need to be called at different times during the week. Question: Is Windows Scheduler (running on a Server 2008 box) any better or worse than scheduling this via a SQL Server job? And why? Thanks

  • iPhone UIControl and Subview

    - by Jack Thompson
    I currently have a UIControl, which has a number of subviews (image, label). Unfortunately when I use addTarget etc. It doesn't detect touches on the subviews. [myCustomView addTarget:self action:@selector(touchedView:) forControlEvents:UIControlEventTouchUpInside]; Is it possible for the UIControl to detect touches on subviews or should i be approaching it differently.

  • Can't get tokens when using OAuth with LinkedIn API

    - by Angela
    Hi, was wondering if anyone can help me to get this basic OAuth implementation to work using the LinkedIn API: The output for the indexes oauth_token and oauth_token_secret are blank. The file I refer to in OAuth.php are a set of classes to help generate the token requests and tokens. That file is here: http://www.easy-share.com/1909603316/OAuth.php <?php session_start(); require_once("OAuth.php"); $app_token = "YOUR APP TOKEN GOES HERE"; $app_key = "YOUR APP KEY GOES HERE"; $domain = "https://api.linkedin.com/uas/oauth"; $sig_method = new OAuthSignatureMethod_HMAC_SHA1(); $test_consumer = new OAuthConsumer($app_token, $app_key, NULL); $callback = "http://".$_SERVER['HTTP_HOST'].$_SERVER['PHP_SELF']."?action=getaccesstoken"; # First time through, get a request token from LinkedIn. if (!isset($_GET['action'])) { $req_req = OAuthRequest::from_consumer_and_token($test_consumer, NULL, "POST", $domain . "/requestToken"); $req_req->set_parameter("oauth_callback", $callback); # part of OAuth 1.0a - callback now in requestToken $req_req->sign_request($sig_method, $test_consumer, NULL); $ch = curl_init(); // make sure we submit this as a post curl_setopt($ch, CURLOPT_POSTFIELDS, ''); //New Line curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0); curl_setopt($ch, CURLOPT_HTTPHEADER,array ( $req_req->to_header() )); curl_setopt($ch, CURLOPT_URL, $domain .

  • Blocking an IP range without using .htaccess

    - by Chris
    I have a WordPress blog that I am hosting using NearlyFreeSpeech.net. Recently, Russians found it and have been comment spamming me. I don't want to have to trash 30+ Cyrillic comments/day, and I don't want to pay for that bandwidth either. I did a little research, and all the commentors are originating from RIPE delegated IP ranges. Because my blog can only interest people living in the American Southeast, I figured the quick and dirty solution would be to use .htaccess to deny connections coming from 62.0.0.0/8 and 80.0.0.0/8 - 91.0.0.0/8. I wrote a .htaccess file that did just this, but the Russians were still getting through! According to NearlyFreeSpeech.net's FAQ, they can't support IP blocking through .htaccess (dirt cheap hosting comes with a price). I can block comments by IP through Wordpress (I think), but I can't figure out a way to block IP ranges or wildcards. Does anybody know of any other way?

  • Zend Framework + Uplodify Flash Uploader Troubles

    - by Richard Knop
    I've been trying to get the Uploadify flash uploader (www.uploadify.com) to work with Zend Framework, with no success so far. I have placed all Uploadify files under /public/flash-uploader directory. In the controller I include all required files and libraries like this: $this->view->headScript()->appendFile('/js/jquery-1.3.2.min.js'); $this->view->headLink()->appendStylesheet('/flash-uploader/css/default.css'); $this->view->headLink()->appendStylesheet('/flash-uploader/css/uploadify.css'); $this->view->headScript()->appendFile('/flash-uploader/scripts/swfobject.js'); $this->view->headScript()->appendFile('/flash-uploader/scripts/jquery.uploadify.v2.1.0.min.js'); And then I activate the plugin like this (#photo is id of the input file field): $(document).ready(function() { $("#photo").uploadify({ 'uploader' : '/flash-uploader/scripts/uploadify.swf', 'script' : 'my-account/flash-upload', 'cancelImg' : '/flash-uploader/cancel.png', 'folder' : 'uploads/tmp', 'queueID' : 'fileQueue', 'auto' : true, 'multi' : true, 'sizeLimit' : 2097152 }); }); As you can see I am targeting the my-account/flash-upload script as a backend processing (my-account is a controller, flash-upload is an action). My form markup looks like this: <form enctype="multipart/form-data" method="post" action="/my-account/upload-public-photo"><ol> <li><label for="photo" class="optional">File Queue<div id="fileQueue"></div></label> <input type="hidden" name="MAX_FILE_SIZE" value="31457280" id="MAX_FILE_SIZE" /> <input type="file" name="photo" id="photo" class="input-file" /></li> <li><div class="button"> <input type="submit" name="upload_public_photo" id="upload_public_photo" value="Save" class="input-submit" /></div></li></ol></form> And yet it's not working. The browse button doesn't even show up as in the demo page, I get only a regular input file field. Any ideas where could the problem be? I've already been staring into the code for hours and I cannot see any mistake anywhere and I'm starting to be exhausted after going through the same 30 lines of code 30 times in a row.

  • Handling Model Inheritance in ASP.NET MVC2 & NHibernate

    - by enth
    I've gotten myself stuck on how to handle inheritance in my model when it comes to my controllers/views. Basic Model: public class Procedure : Entity { public Procedure() { } public int Id { get; set; } public DateTime ProcedureDate { get; set; } public ProcedureType Type { get; set; } } public ProcedureA : Procedure { public double VariableA { get; set; } public int VariableB { get; set; } public int Total { get; set; } } public ProcedureB : Procedure { public int Score { get; set; } } etc... many of different procedures eventually. So, I do things like list all the procedures: public class ProcedureController : Controller { public virtual ActionResult List() { IEnumerable<Procedure> procedures = _repository.GetAll(); return View(procedures); } } but now I'm kinda stuck. Basically, from the list page, I need to link to pages where the specific subclass details can be viewed/edited and I'm not sure what the best strategy is. I thought I could add an action on the ProcedureController that would conjure up the right subclass by dynamically figuring out what repository to use and loading the subclass to pass to the view. I had to store the class in the ProcedureType object. I had to create/implement a non-generic IRepository since I can't dynamically cast to a generic one. public virtual ActionResult Details(int procedureID) { Procedure procedure = _repository.GetById(procedureID, false); string className = procedure.Type.Class; Type type = Type.GetType(className, true); Type repositoryType = typeof (IRepository<>).MakeGenericType(type); var repository = (IRepository)DependencyRegistrar.Resolve(repositoryType); Entity procedure = repository.GetById(procedureID, false); return View(procedure); } I haven't even started sorting out how the view is going to determine which partial to load to display the subclass details. I'm wondering if this is a good approach? This makes determining the URL easy. It makes reusing the Procedure display code easy. Another approach is specific controllers for each subclass. It simplifies the controller code, but also means many simple controllers for the many procedure subclasses. Can work out the shared Procedure details with a partial view. How to get to construct the URL to get to the controller/action in the first place? Time to not think about it. Hopefully someone can show me the light. Thanks in advance.

  • Delphi: Using Enumerators to filter TList<T: class> by class type?

    - by afrazier
    Okay, this might be confusing. What I'm trying to do is use an enumerator to only return certain items in a generic list based on class type. Given the following hierarchy: type TShapeClass = class of TShape; TShape = class(TObject) private FId: Integer; public function ToString: string; override; property Id: Integer read FId write FId; end; TCircle = class(TShape) private FDiameter: Integer; public property Diameter: Integer read FDiameter write FDiameter; end; TSquare = class(TShape) private FSideLength: Integer; public property SideLength: Integer read FSideLength write FSideLength; end; TShapeList = class(TObjectList<TShape>) end; How can I extend TShapeList such that I can do something similar to the following: procedure Foo; var ShapeList: TShapeList; Shape: TShape; Circle: TCircle; Square: TSquare; begin // Create ShapeList and fill with TCircles and TSquares for Circle in ShapeList<TCircle> do begin // do something with each TCircle in ShapeList end; for Square in ShapeList<TSquare> do begin // do something with each TSquare in ShapeList end; for Shape in ShapeList<TShape> do begin // do something with every object in TShapeList end; end; I've tried extending TShapeList using an adapted version of Primoz Gabrijelcic's bit on Parameterized Enumerators using a factory record as follows: type TShapeList = class(TObjectList<TShape>) public type TShapeFilterEnumerator<T: TShape> = record private FShapeList: TShapeList; FClass: TShapeClass; FIndex: Integer; function GetCurrent: T; public constructor Create(ShapeList: TShapeList); function MoveNext: Boolean; property Current: T read GetCurrent; end; TShapeFilterFactory<T: TShape> = record private FShapeList: TShapeList; public constructor Create(ShapeList: TShapeList); function GetEnumerator: TShapeFilterEnumerator<T>; end; function FilteredEnumerator<T: TShape>: TShapeFilterFactory<T>; end; Then I modified Foo to be: procedure Foo; var ShapeList: TShapeList; Shape: TShape; Circle: TCircle; Square: TSquare; begin // Create ShapeList and fill with TCircles and TSquares for Circle in ShapeList.FilteredEnumerator<TCircle> do begin // do something with each TCircle in ShapeList end; for Square in ShapeList.FilteredEnumerator<TSquare> do begin // do something with each TSquare in ShapeList end; for Shape in ShapeList.FilteredEnumerator<TShape> do begin // do something with every object in TShapeList end; end; However, Delphi 2010 is throwing an error when I try to compile Foo about Incompatible types: TCircle and TShape. If I comment out the TCircle loop, then I get a similar error about TSquare. If I comment the TSquare loop out as well, the code compiles and works. Well, it works in the sense that it enumerates every object since they all descend from TShape. The strange thing is that the line number that the compiler indicates is 2 lines beyond the end of my file. In my demo project, it indicated line 177, but there's only 175 lines. Is there any way to make this work? I'd like to be able to assign to Circle directly without going through any typecasts or checking in my for loop itself.

  • Android Marketplace Error: "The server could not process your apk. Try again."

    - by jdandrea
    I have an updated apk - tested successfully on various devices and simulator instances - with the following manifest: <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.myCompany.appName" android:versionCode="2" android:versionName="1.0.1"> <uses-sdk android:minSdkVersion="3" android:targetSdkVersion="5" /> <uses-permission android:name="android.permission.INTERNET" /> <supports-screens android:largeScreens="true" android:normalScreens="true" android:smallScreens="true" /> <application android:icon="@drawable/icon" android:label="@string/icon_name" android:debuggable="false"> <activity android:name=".myActivity" android:configChanges="keyboardHidden|orientation"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> </application> </manifest> When I post to Android Marketplace as an upgrade to my existing 1.0 app, I get the aforementioned ambiguous message: "The server could not process your apk. Try again." I've searched elsewhere for this message in hopes of finding out what might be happening, to no avail. (A popular suggestion is to move the uses-sdk element to the top of the manifest, but as you can see it's already at the top.) Clues welcome/appreciated. Update: I just tried to upload the same file again. Now I get a new message: The new apk's versionCode (2) in AndroidManifest.xml must be higher than the old apk's versionCode (2). The server could not process your apk. Try again. Soooo Marketplace did get my upgraded apk after all? (The very first accepted apk's versionCode was 1, so this update was of course bumped to 2.) Confused … Bumping it up to 3 and trying again. Surprise surprise, I get the original "could not process" error all over again. Going in circles. Hmm ... :( Nuther Update: If I exit and re-enter the Marketplace page, now it shows that the app has been uploaded! Except there's no app icon. Curiouser and curiouser ... and this is all happening with a cache-cleared (standards-friendly) browser to boot. So - do I trust the upload? Or start over ... with versionCode="4"? All I want is to get a solid "Upload successful, here's the icon, ready to publish" type of response.

  • Best free (or cheap) ASP.NET based CMS for a club/association?

    I've been looking for a simple, intuitive ASP.NET based CMS to handle my club/association site. It should be based on ASP.NET so I can add some extra specific pages offer a membership system, e.g. I want to be able to define members which can e.g. comment posts, while anonymous users can only read (no active participation) have features like news, forums, blogs, picture gallery be simple and easy to use I've been looking at GraffitiCMS: so far my favorite, but it has no forum, and no membership system, and no future, it seems - no development whatsoever in over a year :-( Sitefinity: had extreme trouble even getting it installed, and when it's finally up and running, I find it overly complicated and not intuitive at all Umbraco: same problem - hard to install, hard to get up and running, the intro videos on their site are only available to paying subscribers (what's up with that deal???)..... DotNetNuke: seems like a major overkill Community Server: seems like a major overkill - and seems to be more and more commercial, only Any others I've missed that I should have definitely looked at ??

  • Missing audio and problems playing FLV video converted from 720p .mov file with FFMPEG

    - by undefined
    I have some .mov video files recorded from a JVC GC-FM1 HD video camera in 720p mode. I have FFMPEG running on a Linux box that I upload files to and have them encoded into FLV format. The video appears to be encoding ok but there is no audio in the resulting FLV file and when I play it back in Flash Player in a browser or on Adobe Media Player, the video pauses at the start. It appears that Adobe Media Player waits for the progress bar to reach the end of the video before starting the playback - i.e. the video will load, the picture pauses, the progress bar seeks to the end as if the video was playing then when it reaches the end the video picture starts. There is no audio on the video. I am noticing this in the video player I have built with Flash 8 using an FLVPlayback component and attached seekBar. The seek bar will start moving as if the video is playing but the picture remains paused.
