  • C# unit test code questions continue

    - by 5YrsLaterDBA
    more questions after questions in here: http://stackoverflow.com/questions/2714073/c-unit-test-code-questions I found the VS unit test testframe treat private and protected method in the same way but deferent with public method. The following is the generated code for a private method: /// <summary> ///A test for recordLogin ///</summary> [TestMethod()] [DeploymentItem("SystemSoftware.exe")] public void recordLoginTest() { User_Accessor target = new User_Accessor(); // TODO: Initialize to an appropriate value Guid userId = new Guid(); // TODO: Initialize to an appropriate value string action = string.Empty; // TODO: Initialize to an appropriate value Users user = null; // TODO: Initialize to an appropriate value AndeDBEntities db = null; // TODO: Initialize to an appropriate value bool expected = false; // TODO: Initialize to an appropriate value bool actual; actual = target.recordLogin(userId, action, user, db); Assert.AreEqual(expected, actual); Assert.Inconclusive("Verify the correctness of this test method."); } questions: [DeploymentItem("SystemSoftware.exe")] is for private and protected methods, why needs it and what is it for? In my original class/file, if I point to the original method and try to "Find All References". The reference in the unit test class/file will not show up for private and protected methods but it will show up for all public methods. Why is that? Is it right? 3.

  • How can I disable keep-alive on ASP.NET Web Service client requests?

    - by Matthew Brindley
    I have a few web servers behind an Amazon EC2 load balancer. I'm using TCP balancing on port 80 (rather than HTTP balancing). I have a client polling a Web Service (running on all web servers) for new items every few seconds. However, the client seems to stay connected to one server and polls that same server each time. I've tried using ServicePointManager to disable KeepAlive, but that didn't change anything. The outgoing connection still had its "connection: keep-alive" HTTP header, and the server kept the TCP connection open. I've also tried adding an override of GetWebRequest to the proxy class created by VS, which inherits from SoapHttpClientProtocol, but I still see the keep-alive header. If I kill the client's process and restart, it'll connect to a new server via the load balancer, but it'll continue polling that new server forever. Is there a way to force it to connect to a random server each time? I want the load from the one client to be spread across all of the web servers. The client is written in C# (as is the server) and uses a Web Reference (not a Service Reference), which points to the load balancer.

  • clientaccesspolicy.xml not being requested via HTTPS

    - by Philip
    I have a silverlight app that has been using http to communicate w/self-hosted WCF services during development. I am now securing the services via https. I am getting an error I had back at the beginning of the project: "An error occurred while trying to make a request to URI 'https://localhost:8303/service'. This could be due to attempting to access a service in a cross-domain way without a proper cross-domain policy in place, or a policy that is unsuitable for SOAP services. You may need to contact the owner of the service to publish a cross-domain policy file and to ensure it allows SOAP-related HTTP headers to be sent. This error may also be caused by using internal types in the web service proxy without using the InternalsVisibleToAttribute attribute. Please see the inner exception for more details." My clientaccesspolicy.xml file is setup to allow access from http://* and https://*. The only difference is using http vs https. The issue is I can usually see (via Fiddler) the clientaccesspolicy.xml file being requested, but now I cannot. I'm assuming it is failing because of this. Any ideas?

  • Editing 8bpp indexed Bitmaps

    - by Pedro Sá
    hi, i'm trying to edit the pixels of a 8bpp. Since this PixelFormat is indexed i'm aware that it uses a Color Table to map the pixel values. Even though I can edit the bitmap by converting it to 24bpp, 8bpp editing is much faster (13ms vs 3ms). But, changing each value when accessing the 8bpp bitmap results in some random rgb colors even though the PixelFormat remains 8bpp. I'm currently developing in c# and the algorithm is as follows: (C#) 1- Load original Bitmap at 8bpp 2- Create Empty temp Bitmap with 8bpp with the same size as the original 3-LockBits of both bitmaps and, using P/Invoke, calling c++ method where I pass the Scan0 of each BitmapData object. (I used a c++ method as it offers better performance when iterating through the Bitmap's pixels) (C++) 4- Create a int[256] palette according to some parameters and edit the temp bitmap bytes by passing the original's pixel values through the palette. (C#) 5- UnlockBits. My question is how can I edit the pixel values without having the strange rgb colors, or even better, edit the 8bpp bitmap's Color Table? Regards, Pedro

  • Date since 1600 to NSDate?

    - by Steven Fisher
    I have a date that's stored as a number of days since January 1, 1600 that I need to deal with. This is a legacy date format that I need to read many, many times in my application. Previously, I'd been creating a calendar, empty date components and root date like this: self.gregorian = [[[NSCalendar alloc] initWithCalendarIdentifier: NSGregorianCalendar ] autorelease]; id rootComponents = [[[NSDateComponents alloc] init] autorelease]; [rootComponents setYear: 1600]; [rootComponents setMonth: 1]; [rootComponents setDay: 1]; self.rootDate = [gregorian dateFromComponents: rootComponents]; self.offset = [[[NSDateComponents alloc] init] autorelease]; Then, to convert the integer later to a date, I use this: [offset setDay: theLegacyDate]; id eventDate = [gregorian dateByAddingComponents: offset toDate: rootDate options: 0]; (I never change any values in offset anywhere else.) The problem is I'm getting a different time for rootDate on iOS vs. Mac OS X. On Mac OS X, I'm getting midnight. On iOS, I'm getting 8:12:28. (So far, it seems to be consistent about this.) When I add my number of days later, the weird time stays. OS | legacyDate | rootDate | eventDate ======== | ========== | ==========================|========================== Mac OS X | 143671 | 1600-01-01 00:00:00 -0800 | 1993-05-11 00:00:00 -0700 iOS | 143671 | 1600-01-01 08:12:28 +0000 | 1993-05-11 07:12:28 +0000 In the previous release of my product, I didn't care about the time; now I do. Why the weird time on iOS, and what should I do about it? (I'm assuming the hour difference is DST.) I've tried setting the hour, minute and second of rootComponents to 0. This has no impact. If I set them to something other than 0, it adds them to 8:12:28. I've been wondering if this has something to do with leap seconds or other cumulative clock changes. Or is this entirely the wrong approach to use on iOS?

  • What is the correct way to pass an object to WebApi RC controller

    - by Diver Dan
    I have a webapi project running rc I have a very basic controlller like [System.Web.Http.HttpPost] public void Update(Business business) { //if (business.Id == Guid.Empty) //{ // throw new HttpResponseException("Business ID not provided", HttpStatusCode.BadRequest); //} _repository.Update(business); //if (!isUpdated) //{ // throw new HttpResponseException("Business not found", HttpStatusCode.NotFound); //} } I found an example using HttpClient however it doesnt work with rc using (var client = new HttpClient()) { try { string url = string.Format("{0}{1}", ConfigurationManager.AppSettings["ApiBaseUrl"].ToString(),apiMethod); HttpRequestMessage request = new HttpRequestMessage(); MediaTypeFormatter[] formatter = new MediaTypeFormatter[] { new JsonMediaTypeFormatter() }; var content = request.CreateContent<Business>( business, MediaTypeHeaderValue.Parse("application/json"), formatter, new FormatterSelector()); HttpResponseMessage response = client.PostAsync(url, content).Result; return response.Content.ToString(); } catch (Exception ex) { return null; } } I get an error Method not found: 'Void System.Net.Http.Headers.HttpHeaders.AddWithoutValidation(System.String, System.String)'. Passing the data from jquery is a piece of cake however I need call the api from code behind vs client side. Can someone point me in the right direction for calling the webapi? Thank you

  • stack and heap issue for iPhone memory management

    - by Forrest
    From this post I got know that the Objective-C runtime does not allow objects to be instantiated on the stack, but only on the heap; this means that you don’t have “automatic objects”, nor things like auto_ptr objects to help you manage memory; Someone give one example in post Objective C: Memory Allocation on stack vs. heap NSString* str = @"hello"; but this NSString is also not allocated in stack. Feel odd that this str is static. (Who can explain this ? ) Question here is that why there is no heap ? even mixing c++ together with Object C ? /////////////////////////////// Clear my question /////////////////////////////// I am confused , so questions are not clear. Let me put in this way. 1) All Object C objects should be alloc in stack ? ( I think yes ) 2)In C++, there are stack for memory, so for iOS app, also have stack ? ( I think yes ) 3) for iOS app, if only use Object C, so what is the usage of stack ? what kind of objects should use stack then ?

  • batch file to merge .js files from subfolders into one combined file

    - by Andrew Johns
    I'm struggling to get this to work. Plenty of examples on the web, but they all do something just slightly different to what I'm aiming to do, and every time I think I can solve it, I get hit by an error that means nothing to me. After giving up on the JSLint.VS plugin, I'm attempting to create a batch file that I can call from a Visual Studio build event, or perhaps from cruise control, which will generate JSLint warnings for a project. The final goal is to get a combined js file that I can pass to jslint, using: cscript jslint.js < tmp.js which would validate that my scripts are ready to be combined into one file for use in a js minifier, or output a bunch of errors using standard output. but the js files that would make up tmp.js are likely to be in multiple subfolders in the project, e.g: D:\_projects\trunk\web\projectname\js\somefile.debug.js D:\_projects\trunk\web\projectname\js\jquery\plugins\jquery.plugin.js The ideal solution would be to be able to call a batch file along the lines of: jslint.bat %ProjectPath% and this would then combine all the js files within the project into one temp js file. This way I would have flexibility in which project was being passed to the batch file. I've been trying to make this work with copy, xcopy, type, and echo, and using a for do loop, with dir /s etc, to make it do what I want, but whatever I try I get an error.

  • .NET EventHandlers - Generic or no?

    - by Chris Marasti-Georg
    Every time I start in deep in a C# project, I end up with lots of events that really just need to pass a single item. I stick with the EventHandler/EventArgs practice, but what I like to do is have something like: public delegate void EventHandler<T>(object src, EventArgs<T> args); public class EventArgs<T>: EventArgs { private T item; public EventArgs(T item) { this.item = item; } public T Item { get { return item; } } } Later, I can have my public event EventHandler<Foo> FooChanged; public event EventHandler<Bar> BarChanged; However, it seems that the standard for .NET is to create a new delegate and EventArgs subclass for each type of event. Is there something wrong with my generic approach? EDIT: The reason for this post is that I just re-created this in a new project, and wanted to make sure it was ok. Actually, I was re-creating it as I posted. I found that there is a generic EventHandler<TEventArgs, so you don't need to create the generic delegate, but you still need the generic EventArgs<T class, because TEventArgs: EventArgs. Another EDIT: One downside (to me) of the built-in solution is the extra verbosity: public event EventHandler<EventArgs<Foo>> FooChanged; vs. public event EventHandler<Foo> FooChanged; It can be a pain for clients to register for your events though, because the System namespace is imported by default, so they have to manually seek out your namespace, even with a fancy tool like Resharper... Anyone have any ideas pertaining to that?

  • In NHIbernate, why does SaveOrUpdate() update the Version, but SaveOrUpdateCopy() doesn't?

    - by Daniel T.
    I have a versioned entity, and this is what happens when I use SaveOrUpdate() vs. SaveOrUpdateCopy(): // create new entity var entity = new Entity{ Id = Guid.Empty }); Console.WriteLine(entity.Version); // prints out 0 // save the new entity GetNewSession(); entity.SaveOrUpdate(); Console.WriteLine(entity.Version); // prints out 1 GetNewSession(); // loads the persistent entity into the session, so we have to use // SaveOrUpdateCopy() to merge the following transient entity var dbEntity = Database.GetAll<Entity>(); // new, transient entity used to update the persistent entity in the session var newEntity = new Entity{ Id = Guid.Empty }); newEntity.SaveOrUpdateCopy(); Console.WriteLine(entity.Version); // prints out 1, but should be 2 Why is the version number is not updated for SaveOrUpdateCopy()? As I understand it, the transient entity is merged with the persistent entity. The SQL calls confirm that the data is updated. At this point, shouldn't newEntity become persistent, and the version number incremented?

  • How to debug jQuery ajax POST to .NET webservice

    - by Nick
    Hey all. I have a web service that I have published locally. I wrote an HTML page to test the web service. The webservice is expecting a string that will be XML. When I debug the web service from within VS everything works great. I can use FireBug and see that my web service is indeed being hit by they AJAX call. After deploying the web service locally to IIS it does not appear to be working. I need to know the best way to trouble shoot this problem. My AJAX js looks like this: function postSummaryXml(data) { $.ajax({ type: 'POST', url: 'http://localhost/collection/services/datacollector.asmx/SaveSummaryDisplayData', data: { xml: data }, error: function(result) { alert(result); }, success: function(result) { alert(result); } }); The web method looks like so: [WebMethod] public string SaveSummaryDisplayData(string xml) { XmlDocument xmlDocument = new XmlDocument(); xmlDocument.LoadXml(xml); XmlParser parser = new XmlParser(xmlDocument); IModel repository = new Repository(); if(repository.AddRecord("TestData",parser.TestValues)) { return "true"; } return "false"; } } I added the return string to the web method in an attempt to ensure that the web-service is really hit from the ajax. The problem is this: In FF the 'Success' function is always called yet the result is always 'NULL'. And the web method does not appear to have worked (no data saved). In IE the 'Error' function is called and the response is server error: 500. I think (believe it or not) IE is giving me a more accurate indication that something is wrong but I cannnot determine what the issue is. Can someone please suggest how I should expose the specific server error message? Thanks for the help!

  • Altering URLs and mapping - path_prefix? - Ruby on Rails...

    - by bgadoci
    Ok, so I am working on a blog application of sorts. Thus far, it allows for a user to sign up for their own account, create posts, tags, comments, etc. I have just implemented the ability to use www.myapp.com/brandon to set @user to find by username and therefore correctly display the users information at each url. So when you go to www.myapp.com/brandon you see all Brandon's posts, tags, and comments associated with those posts, etc. Works great. I implementing this URL mapping through the routes.rb file by adding the following: map.username_link '/:username', :controller => 'posts', :action => 'index' And then just setting the @user variable in the PostController and corresponding views to find_by_username. Now the issue is this. Once at www.myapp.com/brandon when you click on a post title, it sends to myapp.com/posts/id without the username in the URL which blows up my view because nothing is being set for the @user variable. How do I tell Rails to create the link reading www.myapp.com/brandon/posts/id vs www.myapp.com/posts/id and then map that action? I am assuming this will involve some code in the view, and then adding another line in the routes.rb file, map.subdomain_link '/:username/posts/:id', :controller => 'posts', :action => 'show' and adding the @user variable to the PostController#show action, but not totally sure if this is even the right approach. UPDATE: I have been reading about :path_prefix and seems like it might be what I am looking for. I have tried to implement simply by adding map.resources :posts, :path_prefix => '/:user_username/:post_id' to the routes.rb file but not working (even after server restart). I am sure this is not correct but wanted to let you know what I have tried.

  • Designing a fluid Javascript interface to hide callback asynchrony

    - by Anurag
    How would I design an API to hide the asynchronous nature of AJAX and HTTP requests, or basically delay it to provide a fluid interface. To show an example from Twitter's new Anywhere API: // get @ded's first 20 statuses, filter only the tweets that // mention photography, and render each into an HTML element T.User.find('ded').timeline().first(20).filter(filterer).each(function(status) { $('div#tweets').append('<p>' + status.text + '</p>'); }); function filterer(status) { return status.text.match(/photography/); } vs this (asynchronous nature of each call is clearly visible) T.User.find('ded', function(user) { user.timeline(function(statuses) { statuses.first(20).filter(filterer).each(function(status) { $('div#tweets').append('<p>' + status.text + '</p>'); }); }); }); It finds the user, gets their tweet timeline, filters only the first 20 tweets, applies a custom filter, and ultimately uses the callback function to process each tweet. I am guessing that a well designed API like this should work like a query builder (think ORMs) where each function call builds the query (HTTP URL in this case), until it hits a looping function such as each/map/etc., the HTTP call is made and the passed in function becomes the callback. An easy development route would be to make each AJAX call synchronous, but that's probably not the best solution. I am interested in figuring out a way to make it asynchronous, and still hide the asynchronous nature of AJAX.

  • Problem with apostrophes and other special characters when using aspell in windows

    - by Loftx
    Hi there, We seem to be having a problem with the spell checker on our content management system where it marks the ve part of We’ve as a misspelling. The spellchecker uses aspell which is called from a script on the server which executes the cmd.exe and uses it to pipe a file into aspell (it's a long winded way I know, but our server side programming langauge (ColdFusion) doesn't support writing to stdin for executables). Aspell is called by executing: c:\windows\system32\cmd.exe /c type d:\path_to_file\file.txt | "C:\Program Files\Aspell\bin\aspell" --lang=en -a Where file.txt contains the text to be spelled e.g. ^Oh have We’ve (the carat is added to prevent piping problems I believe). Aspell then output: @(#) International Ispell Version 3.1.20 (but really Aspell 0.50.3) * * * & ve 62 12: vie, voe, V, v, veg, vet, Be, Ce, be, Ev, E, e, vex, VA, VI, Va, Vi, vi, we, VD, VF, VG, VJ, VP, VT, Vt, vb, vs, DE, De, Fe, GE, Ge, He, IE, Le, ME, Me, NE, Ne, OE, PE, Re, SE, Se, Te, Xe, he, me, re, ye, Ave, Eve, Ive, ave, eve, VAR, var, veer, vier, view, vow However, we have a dev site, with the same version of Aspell, and when the same file is used it outputs with no misspellings. Both servers are running Aspell 0.50.3 on Windows server 2003, but there could be other differences in configuration: @(#) International Ispell Version 3.1.20 (but really Aspell 0.50.3) I'm wondering if the problem is to do with the piping part of the process or something different in the Aspell configuration. Does anyone have any ideas? Cheers, Tom

  • Vote on Pros and Cons of Java HTML to XML cleaners

    - by George Bailey
    I am looking to allow HTML emails (and other HTML uploads) without letting in scripts and stuff. I plan to have a white list of safe tags and attributes as well as a whitelist of CSS tags and value regexes (to prevent automatic return receipt). I asked a question: Parse a badly formatted XML document (like an HTML file) I found there are many many ways to do this. Some systems have built in sanitizers (which I don't care so much about). This page is a very nice listing page but I get kinda lost http://java-source.net/open-source/html-parsers It is very important that the parsers never throw an exception. There should always be best guess results to the parse/clean. It is also very important that the result is valid XML that can be traversed in Java. I posted some product information and said Community Wiki. Please post any other product suggestions you like and say Community Wiki so they can be voted on. Also any comments or wiki edits on what part of a certain product is better and what is not would be greatly appreciated. (for example,, speed vs accuracy..) It seems that we will go with either jsoup (seems more active and up to date) or TagSoup (compatible with JDK4 and been around awhile). A +1 for any of these products would be if they could convert all style sheets into inline style on the elements.

  • WPF: How to data bind an object to an element and apply a data template through code?

    - by Boris
    I have created a class LeagueMatch. public class LeagueMatch { public string Home { get { return home; } set { home = value; } } public string Visitor { get { return visitor; } set { visitor = value; } } private string home; private string visitor; public LeagueMatch() { } } Next, I have defined a datatemplate resource for LeagueMatch objects in XAML: <DataTemplate x:Key="MatchTemplate" DataType="{x:Type entities:LeagueMatch}"> <Grid Name="MatchGrid" Width="140" Height="50" Margin="5"> <Grid.RowDefinitions> <RowDefinition Height="*" /> <RowDefinition Height="*" /> <RowDefinition Height="*" /> </Grid.RowDefinitions> <TextBlock Grid.Row="0" Text="{Binding Home}" /> <TextBlock Grid.Row="1" Text="- vs -" /> <TextBlock Grid.Row="2" Text="{Binding Visitor}" /> </Grid> </DataTemplate> In the XAML code-behind, I want to create a ContentPresenter object and to set it's data binding to a previously initialized LeagueMatch object and apply the defined data template. How is that supposed to be done? Thanks.

  • Subversion versus Vault

    - by WebDude
    I'm currently reviewing the benefits of moving from SVN to a SourceGear Vault. Has anyone got advice or a link to a detailed comparison between the two? Bear in mind I would have to move my current Source Control system across which works strongly in SVN's favor Here is some info I have found out thus far from my own investigations. I have been taking some time tests between the two and vault seems to perform most operations much faster. Time tests used the same server as the repository, the same workstation client, and the same project. Time Comparisons SVN Add/Commit    12:30 Get Latest Revision    5:35 Tagging/Labelling    0:01 Branching    N/A - I don't think true branching exists in SVN Vault Add/Commit    4:45 Get Latest Revision    0:51 Tagging/Labelling    0:30 Branching    3:23 (can't get this to format correctly) I also found an online source comparing some other points. This is the kind of information i'm looking for. Usage Comparisons Subversion is edit/merge/commit only. Vault allows you to do either edit/merge/commit or checkout/edit/checkin. Vault looks and acts just like VSS, which makes the learning curve effectively zero for VSS users. Vault has a VS plugin, but it only works if you're going to run in checkout-mode. Subversion has clients for pretty much every OS you can imagine; Vault has a GUI client for Windows and a command line client for Mono. Both will support remote work, since both use HTTP as their transport (Subversion uses extended DAV, Vault uses SOAP). Subversion installation, especially w/ Apache, is more complex. Subversion has a lot of third party support. Vault has just a few things. My question Has anyone got advice or a link to a detailed comparison between the two?

  • Synchronize DataGrid and DataForm in Silverlight 3

    - by SpiralGray
    I've been banging my head against the wall for a couple of days on this and it's time to ask for help. I've got a DataGrid and DataForm on the same UserControl. I'm using an MVVM approach so there is a single ViewModel for the UserControl. That ViewModel has a couple of properties that are relevant to this discussion: public ObservableCollection<VehicleViewModel> Vehicles { get; private set; } public VehicleViewModel SelectedVehicle { get { return selectedVehicle; } private set { selectedVehicle = value; OnPropertyChanged( "SelectedVehicle" ); } } In the XAML I've got the DataGrid and DataForm defined as follows: <data:DataGrid SelectionMode="Single" ItemsSource="{Binding Vehicles}" SelectedItem="{Binding SelectedVehicle, Mode=TwoWay}" AutoGenerateColumns="False" IsReadOnly="True"> <dataFormToolkit:DataForm CurrentItem="{Binding SelectedVehicle}" /> So as the SelectedItem changes on the DataGrid it should push that change back to the ViewModel and when the ViewModel raises the OnPropertyChanged the DataForm should refresh itself with the information for the newly-selected VehicleViewModel. However, the setter for SelectedVehicle is never being called and in the Output window of VS I'm seeing the following error: System.Windows.Data Error: ConvertBack cannot convert value 'xxxx.ViewModel.VehicleViewModel' (type 'xxxx.ViewModel.VehicleViewModel'). BindingExpression: Path='SelectedVehicle' DataItem='xxxx.ViewModel.MainViewModel' (HashCode=31664161); target element is 'System.Windows.Controls.DataGrid' (Name=''); target property is 'SelectedItem' (type 'System.Object').. System.MethodAccessException: xxxx.ViewModel.MainViewModel.set_SelectedVehicle(xxxx.ViewModel.VehicleViewModel) It sounds like it's having a problem converting from a VehicleViewModel to an object (or back again), but I'm confused as to why that would be (or even if I'm on the right track with that assumption). Each row/item in the DataGrid should be a VehicleViewModel (because the ItemsSource is bound to an ObservableCollection of that type), so when the SelectedItem changes it should be dealing with an instance of VehicleViewModel. Any insight would be appreciated.

  • Need advice on OOP philosophy

    - by David Jenings
    I'm trying to get the wheels turning on a large project in C#. My previous experience is in Delphi, where by default every form was created at applicaton startup and form references where held in (gasp) global variables. So I'm trying to adapt my thinking to a 100% object oriented environment, and my head is spinning just a little. My app will have a large collection of classes Most of these classes will only really need one instance. So I was thinking: static classes. I'm not really sure why, but much of what I've read here says that if my class is going to hold a state, which I take to mean any property values at all, I should use a singleton structure instead. Okay. But there are people out there who for reasons that escape me, think that singletons are evil too. None of these classes is in danger of being used anywhere except in this program. So they could certainly work fine as regular objects (vs singletons or static classes) Then there's the issue of interaction between objects. I'm tempted to create a Global class full of public static properties referencing the single instances of many of these classes. I've also considered just making them properties (static or instance, not sure which) of the MainForm. Then I'd have each of my classes be aware of the MainForm as Owner. Then the various objects could refer to each other as Owner.Object1, Owner.Object2, etc. I fear I'm running out of electronic ink, or at least taxing the patience of anyone kind enough to have stuck with me this long. I hope I have clearly explained my state of utter confusion. I'm just looking for some advice on best practices in my situation. All input is welcome and appreciated. Thanks in advance, David Jennings

  • Getting Visual Studio macros in console app

    - by Paul Steckler
    In a Visual Studio extension, you can get the default include paths for all projects with C# code like: String dirs = dte2.get_Properties("Projects", "VCDirectories"); where dte2 is the Visual Studio application object. Usually, those directories contain macros like $(INCLUDE). You can expand those macros by looking at dte2.Solution.Projects, finding the relevant project in that collection; from the project, look at project.Configurations, find the relevant configuration, and call its Evaluate method. In VS2005/VS2008, there's a .vssettings file that contains the VCDirectories. In VS2010, there's a property sheet with the same information. A console application can just parse those files -- great. But how can you expand the macros? As a first step, I tried instantiating a VCProjectEngine object in a console app, but that just resulted in a COM failure. So I don't know how to instantiate a VCProject object in order to follow the same strategy I used in a VS extension. Where are the macro bindings stored?

  • Javascript: Collision detection

    - by jack moore
    Hello, could someone please help me to understand how collision detection works in JS? I can't use jQuery or gameQuery - already using prototype - so, I'm looking for something very simple. Not asking for complete solution, just point me to the right direction. Let's say there's: <div id="ball"></div> and <div id="someobject0"></div> Now the ball is moving (any direction). "Someobject"(0-X) is already pre-defined and there's 20-60 of them randomly positioned like this: #someobject {position: absolute; top: RNDpx; left: RNDpx;} I can create an array with "someobject(X)" positions and test collision while the "ball" is moving... Something like: for(var c=0; c<objposArray.length; c++){ ........ and code to check ball's current position vs all objects one by one.... } But I guess this would be a "noob" solution and it looks pretty slow. Is there anything better?

  • Using graphical ActiveX (COM) controls in WinForms project

    I have a collection (set) of ActiveX controls. I recieved them from our vendor company. I created a wrappers for them using tlbimp.exe and aximp.exe. All non-graphical controls work good. All graphical controls don't react on some methods. When I call their methods I get: TargetInvocativeException (InnerException is null). or Attempt to read/write protected memory. Our vendor company assure that their graphical activex controls work good. But they don't provide support service, so I have to find solution of my problem alone. And some more, All graphical activex controls don't react on mouseclick or any other mouse manipulations. But documentation says: it must change the color on mouse click. Maybe, someone have same symptoms and can help me ! I googled over that problem many pages but they don't help me. Maybe it's some Visual Studio settings or compiler options ? I use VS 2005.

  • detecting pauses in a spoken word audio file using pymad, pcm, vad, etc

    - by james
    First I am going to broadly state what I'm trying to do and ask for advice. Then I will explain my current approach and ask for answers to my current problems. Problem I have an MP3 file of a person speaking. I'd like to split it up into segments roughly corresponding to a sentence or phrase. (I'd do it manually, but we are talking hours of data.) If you have advice on how to do this programatically or for some existing utilities, I'd love to hear it. (I'm aware of voice activity detection and I've looked into it a bit, but I didn't see any freely available utilities.) Current Approach I thought the simplest thing would be to scan the MP3 at certain intervals and identify places where the average volume was below some threshold. Then I would use some existing utility to cut up the mp3 at those locations. I've been playing around with pymad and I believe that I've successfully extracted the PCM (pulse code modulation) data for each frame of the mp3. Now I am stuck because I can't really seem to wrap my head around how the PCM data translates to relative volume. I'm also aware of other complicating factors like multiple channels, big endian vs little, etc. Advice on how to map a group of pcm samples to relative volume would be key. Thanks!

  • InvalidCastException in DataGridView

    - by Max Yaffe
    (Using VS 2010 Beta 2 - .Net 4.0 B2 Rel) I have a class, MyTable, derived from BindingList where S is a struct. S is made up of several other structs, for example: public class MyTable<S>:BindingList<S> where S: struct { ... } public struct MyStruct { public MyReal r1; public MyReal r2; public MyReal R1 {get{...} set{...}} public MyReal R2 {get{...} set{...}} ... } public struct MyReal { private Double d; private void InitFromString(string) {this.d = ...;} public MyReal(Double d) { this.d = d;} public MyReal(string val) { this.d = default(Double); InitFromString(val);} public override string ToString() { return this.real.ToString();} public static explicit operator MyReal(string s) { return new MyReal(s);} public static implicit operator String(MyReal r) { return r.ToString();} ... } OK, I use the MyTable as a binding source for a DataGridView. I can load the data grid easily using InitFromString on individual fields in MyStruct. The problem comes when I try to edit a value in a cell of the DataGridView. Going to the first row, first column, I change the value of the existing number. It gives an exception blizzard, the first line of which says: System.FormatException: Invalid cast from 'System.String' to 'MyReal' I've looked at the casting discussions and reference books but don't see any obvious problems. Any ideas?

  • SQL Server 2005 Reporting Services and the Report Viewer

    - by Kendra
    I am having an issue embedding my report into an aspx page. Here's my setup: 1 Server running SQL Server 2005 and SQL Server 2005 Reporting Services 1 Workstation running XP and VS 2005 The server is not on a domain. Reporting Services is a default installation. I have one report called TestMe in a folder called TestReports using a shared datasource. If I view the report in Report Manager, it renders fine. If I view the report using the http ://myserver/reportserver url it renders fine. If I view the report using the http ://myserver/reportserver?/TestReports/TestMe it renders fine. If I try to view the report using http ://myserver/reportserver/TestReports/TestMe, it just goes to the folder navigation page of the home directory. My web application is impersonating somebody specific to get around the server not being on a domain. When I call the report from the report viewer using http ://myserver/reportserver as the server and /TestReports/TestMe as the path I get this error: For security reasons DTD is prohibited in this XML document. To enable DTD processing set the ProhibitDtd property on XmlReaderSettings to false and pass the settings into XmlReader.Create method. When I change the server to http ://myserver/reportserver? I get this error when I run the report: Client found response content type of '', but expected 'text/xml'. The request failed with an empty response. I have been searching for a while and haven't found anything that fixes my issue. Please let me know if there is more information needed. Thanks in advance, Kendra
