  • RhinoMocks: how to test if method was called when using PartialMock

    - by epitka
    I have a clas that is something like this public class MyClass { public virtual string MethodA(Command cmd) { //some code here} public void MethodB(SomeType obj) { // do some work MethodA(command); } } I mocked MyClass as PartialMock (mocks.PartialMock<MyClass>) and I setup expectation for MethodA var cmd = new Command(); //set the cmd to expected state Expect.Call(MyClass.MethodA(cmd)).Repeat.Once(); Problem is that MethodB calls actual implementation of MethodA instead of mocking it up. I must be doing something wrong (not very experienced with RhinoMocks). How do I force it to mock MetdhodA? Here is the actual code: var cmd = new SetBaseProductCoInsuranceCommand(); cmd.BaseProduct = planBaseProduct; var insuredType = mocks.DynamicMock<InsuredType>(); Expect.Call(insuredType.Code).Return(InsuredTypeCode.AllInsureds); cmd.Values.Add(new SetBaseProductCoInsuranceCommand.CoInsuranceValues() { CoInsurancePercent = 0, InsuredType = insuredType, PolicySupplierType = ppProvider }); Expect.Call(() => service.SetCoInsurancePercentages(cmd)).Repeat.Once(); mocks.ReplayAll(); //act service.DefaultCoInsurancesFor(planBaseProduct); //assert service.AssertWasCalled(x => x.SetCoInsurancePercentages(cmd),x=>x.Repeat.Once());

  • Add items from one array to another

    - by Peterim
    I have two arrays: 1) The first array: array( [0] => array( [code] => code_1 [value] => xxx [1] => array( [code] => code_2 [value] => xxx [2] => array( [code] => code_3 [value] => xxx 2) The second array: array( [0] => array( [settingcode] => code_1 [value] => xxx [1] => array( [settingcode] => code_2 [value] => xxx [2] => array( [settingcode] => code_3 [value] => xxx [3] => array( [settingcode] => code_4 [value] => xxx [4] => array( [settingcode] => code_5 [value] => xxx How can add two missing items (code_4 and code_5) from array2 to array1? Thank you!

  • JUnit test failing - complaining of missing data that was just inserted

    - by Collin Peters
    I have an extremely odd problem in my JUnit tests that I just can't seem to nail down. I have a multi-module java webapp project with a fairly standard structure (DAO's, service clasess, etc...). Within this project I have a 'core' project which contains some abstracted setup code which inserts a test user along with the necessary items for a user (in this case an 'enterprise', so a user must belong to an enterprise and this is enforced at the database level) Fairly simple so far... but here is where the strangeness begins some tests fail to run and throw a database exception where it complains that a user cannot be inserted because an enterprise does not exist. But it just created the enterprise in the preceding line of code! And there was no errors in the insertion of the enterprise. Stranger yet, if this test class is run by itself everything works fine. It is only when the test is run as part of the project that it fails! And the exact same abstracted code was run by 10+ tests before the one that fails! f I have been banging my head against a wall with this for days and haven't really made any progress. I'm not even sure what information to offer up to help diagnose this. Using JUnit 4.4, Spring 2.5.6, iBatis 2.3.0, Postgresql 8.3 Switching to org.springframework.jdbc.datasource.DriverManagerDataSource from org.apache.commons.dbcp.BasicDataSource changed the problem. Using DriverManagerDataSource the tests work for the first time, but now all of a sudden a lot of data isn't rolled back in the database! It leaves everything behind. All with no errors Tests fail when run via Eclipse & Maven Please ask for any info which may help me solve my problem!

  • wpf: capturing mouse does not work

    - by amethyste
    hello I am developing an kind of outlook calendar application where I need to make the appointment resizable from mouse. My first try with a thumb did not work properly so I tried another way. What I did is that: 1) on the botton of the appointmennt panel I added a rectangle to figure out the resize zone (the thumb). The appointment panel is put on a grid panel. 2) I intercept down event on the rectangle and send event to this code: private Point startPoint; private void OnResizeElementMouseDown(object sender, MouseButtonEventArgs e) { e.Handled = true; this.MouseMove += new MouseEventHandler(ResizeEndElement_MouseMove); this.MouseLeftButtonUp += new MouseButtonEventHandler(OnResizeElementMouseUp); // some code to perform new height computation Mouse.Capture(this); } where this is the appointment panel that own the thumb. Decreasing height works well. But increasing is more difficult. If I move the mouse very very slowly it's OK, if I speed it up a little bit it tends to leave out the appointment panel and then all MouseMove event are lost. I thought Mouse.Capture() was propose to solve this kind of problem, but in fact not. Does anybody know what is wrong in my code?

  • Facebook JS API: users_getInfo() inside ifUserConnected() deadlock.

    - by serg555
    I am trying to put Facebook connect button on the site and once connected display connected username. But for some reason following code goes into some infinite loop during first connection, and then works fine unless I delete this app from my facebook profile which causes freezing again. Here is a code on FB connect button click: FB.Connect.requireSession(); Here is code directly on the page: <script src="http://static.ak.connect.facebook.com/js/api_lib/v0.4/FeatureLoader.js.php/en_US" type="text/javascript"></script> <script type="text/javascript"> FB.init("123", "/xd_receiver.htm"); FB.ensureInit(function() { FB.Connect.ifUserConnected(function() { FB.Facebook.apiClient.users_getInfo(new Array(FB.Connect.get_loggedInUser()),new Array("name"), function(user, exec) { console.log("logged in:"+user[0].name); }); }, function(){ console.log("guest"); }); }); </script> If I remove FB.Facebook.apiClient.users_getInfo() it works fine, but I need to get username somehow. Any tips? Thanks.

  • Adding an ASP.NET Web User Control to a Control Dynamically

    - by RandomBen
    I have a simple ASP.NET Web User Control. It looks like this: <%@ Control Language="C#" AutoEventWireup="true" CodeBehind="NewsArticle.ascx.cs" Inherits="Website.Controls.NewsArticle" %> <div> <asp:Literal ID="ltlBody" runat="server" /> </div> My code behind looks like this: namespace Website.Controls { public partial class NewsArticle : System.Web.UI.UserControl { public String bodyText { //get { return ltlBody.Text; } set { ltlBody.Text = value; } } } } On a .aspx page I have <asp:Panel ID="pNews" runat="server" /> In the code behind I have: foreach (vwNews news in newsQuery) { NewsArticle article = new NewsArticle(); aticle.bodyText = news.Body; pNews.Controls.Add(article); } Every time I run this code the newsQuery is populated correctly and I get to the line aticle.bodyText = news.Body; and then I received the error article.bodyText threw an exception of type 'System.NullReferenceException' I am not sure what is causing this error message or how to fix it. I would think that there should not be an issue. I tried creating a constructor for my Web User Control so that it would give default values to my properties but that didn't work. Any idea how to make this work? It doesn't seem like it should be that

  • Compare system date with a date field in SQL

    - by JeT_BluE
    I am trying to compare a date record in SQL Server with the system date. In my example the user first register with his name and date of birth which are then stored in the database. The user than logs into the web application using his name only. After logging in, his name is shown on the side where it says "Welcome "player name" using Sessions. What I am trying to show in addition to his name is a message saying "happy birthday" if his date of birth matches the system date. I have tried working with System.DateTime.Now, but what I think is that it is also comparing the year, and what I really want is the day and the month only. I would really appreciate any suggestion or help. CODE In Login page: protected void Button1_Click(object sender, EventArgs e) { String name = TextBox1.Text; String date = System.DateTime.Today.ToShortDateString(); SqlConnection myconn2 = new SqlConnection(ConfigurationManager.ConnectionStrings["User"].ToString()); SqlCommand cmd2 = new SqlCommand(); SqlDataReader reader; myconn2.Open(); cmd2 = new SqlCommand("Select D_O_B from User WHERE Username = @username", myconn2); cmd2.Parameters.Add("@username", SqlDbType.NVarChar).Value = name; cmd2.Connection = myconn2 cmd2.ExecuteNonQuery(); reader = cmd2.ExecuteReader(); while (reader.Read().ToString() == date) { Session["Birthday"] = "Happy Birthday"; } } Note: I using the same reader in the code above this one, but the reader here is with a different connection. Also, reader.Read() is different than reader.HasRows? Code in Web app Page: string date = (string)(Session["Birthday"]); // Retrieving the session Label6.Text = date;

  • Glassfish 3: How do I get and use a developers build so I can navigate a stack trace including Glas

    - by Thorbjørn Ravn Andersen
    I am migrating a JSF 1.1 application to JEE 6 Web profile, and doing it in steps. I am in the process of moving from JSP with JSF 1.1 to Facelets under JSF 1.2 using the jsf-facelets.jar for JSF 1.2, and received an "interesting" stack trace when trying to lookup a key in a Map using a "{Bean.foo.map.key}" where the stacktrace complained about "key" not being a valid integer. (After code introspection I am workarounding it using a number as the key). That bug is not what this question is about. In such a situation it is essential to be able to navigate the source of every line in the stack trace. In Eclipse I normally attach a source jar to every jar on the build path, but in this particular case the Glassfish server adapter creates a library automatically containing the jars. Also there is to my knowledge no debug build of Glassfish where sources are included in the bundle. Glassfish is a non-trivial Maven project, and a bit picky too. I am not very familiar with maven, but have managed to checkout the code from Subversion and build it for the 3.0 tag according to http://wiki.glassfish.java.net/Wiki.jsp?page=V3FullBuildInstructions#section-V3FullBuildInstructions-CheckoutTheWorkspace - it appears to be the code corresponding to the official released 3.0 version. After finishing the "mvn -U install" part, I have then tried to create Eclipse projects by first using "mvn -DdownloadSources=true eclipse:eclipse" and then import them in Eclipse JEE 3.5.2 and specifying the M2_REPO variable but many of the projects still have compilation errors, and I cannot locate any instructions from Oracle about how to do this. I'd appreciate some help in just getting a functional IDE workspace reflecting the 3.0 version of Glassfish. I have Eclipse 3.5.2, Netbeans 6.8 and 6.9 beta, and IntelliJ IDEA 9, and Linux/Windows/OS X do do it on.

  • PHP: SimpleXML and Arrays

    - by acemasta
    When I run this code: foreach($xml->movie as $movie) { if(isset($movie->photos)) { foreach ($movie->photos as $photo) { echo $photo."&nbsp;"; } echo "<hr/>"; } } I get nice output of the actual data, e.g. a row looks like 06397001.jpg 06397002.jpg 06397003.jpg 06397004.jpg 06397005.jpg But when I throw it in an array, it includes all the SimpleXML wrapper tags and the jpgs are not at the root of the array. code: foreach($xml->movie as $movie) { if(isset($movie->photos)) { $photos = array(); foreach ($movie->photos as $photo) { $photos[] = $photo; } } else $photos = ""; var_dump($photos); echo "<hr />"; } e.g. same row looks like array(5) { [0]= object(SimpleXMLElement)#11 (1) { [0]= string(12) "06397001.jpg" } [1]= object(SimpleXMLElement)#12 (1) { [0]= string(12) "06397002.jpg" } [2]= object(SimpleXMLElement)#13 (1) { [0]= string(12) "06397003.jpg" } [3]= object(SimpleXMLElement)#14 (1) { [0]= string(12) "06397004.jpg" } [4]= object(SimpleXMLElement)#15 (1) { [0]= string(12) "06397005.jpg" } } Why is this happening/how can I remove this so I just get an array of the photos at root level like when I echo it? Thanks, sorry for the single line code formatting; was messing up when I tried to paste directly with line breaks.

  • Multiple WPFPreviewHandlers in One Window? Can it be done?

    - by Scott
    Here is the scenario. I am building a part of my desktop app up and I have a need to create a preview handler. I found plenty of examples on the web of a WPF Preview handler, but I wanted to go one step more than just that. Lets say we have multiple documents and I wished to compare them. So the ideal scenario would be able to see documents side by side in a collection. Sort of how BING does their image search. But the more documents I select in a list box, the more documents I can compare all at once. The second Ideal solution would be a tabbed interface. One tab for each document. Sort of like how internet browsers are doing it now. Understand? So here is the question that I have been struggling with. I can get one preview to work in a window, but can’t get the second one to show up. This is all WPF code so maybe im doing something wrong, but can you preview more than one document in a window at a time? My thought is no, because the previewhandler needs a window handler to lock onto. I would love small code sample since COM and handlers aren’t my sort of thing, but I can manage if you are just able to point me down the right track. Here is the code I found for the WPF Handler. http://blogs.microsoft.co.il/blogs/tamir/archive/2008/04/18/using-vista-preview-handlers-in-wpf-application.aspx

  • VB6 Game Development

    - by CVS-2600Hertz-wordpress-com
    Hi All, I am developing a game in VB6 (plz don't ask me why :) ). The storyboard is ready and a rough implementation is underway. I am following a "pure-software-rendering" approach. (i.e. no DirectX, no openGL etc.) Amongst many others, the following "serious" problems exist: 2D alpha transparency reqd. to implement overlays. Parallax implementation to give depth-of-field illusion. Capturing mouse-scroll events globally (as in FPS-es; mapping them to changing weapon). Async sound play with absolute "near-zero-lag". Any ideas anyone. Please suggest any well documented library/ocx or sample-code. Plz do suggest solutions with good performance and as little overhead as possible. Also, anyone who has developed any games, and would be open to sharing her/his code would be highly appreciated. (any well-acknowledged VB games whose source-code i can study??) UPDATE: Here is a screen shot of GearHead Garage. This picture ought to describe what i was attempting in words above... :) Thank You

  • Join Where Rows Don't Exist or Where Criteria Matches...?

    - by Greg
    I'm trying to write a query to tell me which orders have valid promocodes. Promocodes are only valid between certain dates and optionally certain packages. I'm having trouble even explaining how this works (see psudo-ish code below) but basically if there are packages associated with a promocode then the order has to have one of those packages and be within a valid date range otherwise it just has to be in a valid date range. The whole "if PrmoPackage rows exist" thing is really throwing me off and I feel like I should be able to do this without a whole bunch of Unions. (I'm not even sure if that would make it easier at this point...) Anybody have any ideas for the query? if `OrderPromoCode` = `PromoCode` then if `OrderTimestamp` is between `PromoStartTimestamp` and `PromoEndTimestamp` then if `PromoCode` has packages associated with it //yes then if `PackageID` is one of the specified packages //yes code is valid //no invalid //no code is valid Order: OrderID* | OrderTimestamp | PackageID | OrderPromoCode 1 | 1/2/11 | 1 | ABC 2 | 1/3/11 | 2 | ABC 3 | 3/2/11 | 2 | DEF 4 | 4/2/11 | 3 | GHI Promo: PromoCode* | PromoStartTimestamp* | PromoEndTimestamp* ABC | 1/1/11 | 2/1/11 ABC | 3/1/11 | 4/1/11 DEF | 1/1/11 | 1/11/13 GHI | 1/1/11 | 1/11/13 PromoPackage: PromoCode* | PromoStartTimestamp* | PromoEndTimestamp* | PackageID* ABC | 1/1/11 | 2/1/11 | 1 ABC | 1/1/11 | 2/1/11 | 3 GHI | 1/1/11 | 1/11/13 | 1 Desired Result: OrderID | IsPromoCodeValid 1 | 1 2 | 0 3 | 1 4 | 0

  • ~1 second TcpListener Pending()/AcceptTcpClient() lag

    - by cpf
    Probably just watch this video: http://screencast.com/t/OWE1OWVkO As you see, the delay between a connection being initiated (via telnet or firefox) and my program first getting word of it. Here's the code that waits for the connection public IDLServer(System.Net.IPAddress addr,int port) { Listener = new TcpListener(addr, port); Listener.Server.NoDelay = true;//I added this just for testing, it has no impact Listener.Start(); ConnectionThread = new Thread(ConnectionListener); ConnectionThread.Start(); } private void ConnectionListener() { while (Running) { while (Listener.Pending() == false) { System.Threading.Thread.Sleep(1); }//this is the part with the lag Console.WriteLine("Client available");//from this point on everything runs perfectly fast TcpClient cl = Listener.AcceptTcpClient(); Thread proct = new Thread(new ParameterizedThreadStart(InstanceHandler)); proct.Start(cl); } } (I was having some trouble getting the code into a code block) I've tried a couple different things, could it be I'm using TcpClient/Listener instead of a raw Socket object? It's not a mandatory TCP overhead I know, and I've tried running everything in the same thread, etc.

  • Unattended Install of SQL Server 2005 Express with LOCAL Server InstanceName

    - by Jeff
    I'm creating an install package using InnoSetup and installing SQL Server 2005 Express. Here's the code below that appears in my RUN section: Filename: "{app}\SQL Server 2005 Express\SQLEXPR.exe" ; Parameters: "-q /norebootchk /qn reboot=ReallySuppress addlocal=all INSTANCENAME=(LOCAL) SCCCHECKLEVEL=IncompatibleComponents:1;MDAC25Version:0 ERRORREPORTING=2 SQLAUTOSTART=1 SAPWD=passwordhere SECURITYMODE=SQL"; WorkingDir: {app}\SQL Server 2005 Express; StatusMsg: Installing Microsoft SQL Server 2005 Express... Please Wait...;Check:SQLVerifyInstall What I'm trying to accomplish is have the SQL Server package install but only have the instance name itself reference the name of the machine name and nothing more. What I'm receiving instead is a named instance instead of local such as MachineName\SQLEXPRESS which is not what I want to receive. I need a local instance instead of a named instance due to the way my code is written to be able to install and talk with the databases in question. I would change it, trust me, were it not the fact that this install package is a replacement to a previous package that used the MSDE installer. I have to be able to support both through code. Any suggestions are welcome but a clear and concise method to get the installer to quietly install using only the machine name is my main goal. Thanks for the help and support!

  • Multi-threaded library calls in ASP.NET page request.

    - by ProfK
    I have an ASP.NET app, very basic, but right now too much code to post if we're lucky and I don't have to. We have a class called ReportGenerator. On a button click, method GenerateReports is called. It makes an async call to InternalGenerateReports using ThreadPool.QueueUserWorkItem and returns, ending the ASP.NET response. It doesn't provide any completion callback or anything. InternalGenerateReports creates and maintains five threads in the threadpool, one report per thread, also using QueueUserWorkItem, by 'creating' five threads, also with and waiting until calls on all of them complete, in a loop. Each thread uses an ASP.NET ReportViewer control to render a report to HTML. That is, for 200 reports, InternalGenerateReports should create 5 threads 40 times. As threads complete, report data is queued, and when all five have completed, report data is flushed to disk. My biggest problems are that after running for just one report, the aspnet process is 'hung', and also that at around 200 reports, the app just hangs. I just simplified this code to run in a single thread, and this works fine. Before we get into details like my code, is there anything obvious in the above scendario that might be wrong?

  • mysql_real_escape_string() just makes an empty string?

    - by James P
    I am using a jQuery AJAX request to a page called like.php that connects to my database and inserts a row. This is the like.php code: <?php // Some config stuff define(DB_HOST, 'localhost'); define(DB_USER, 'root'); define(DB_PASS, ''); define(DB_NAME, 'quicklike'); $link = mysql_connect(DB_HOST, DB_USER, DB_PASS) or die('ERROR: ' . mysql_error()); $sel = mysql_select_db(DB_NAME, $link) or die('ERROR: ' . mysql_error()); $likeMsg = mysql_real_escape_string(trim($_POST['likeMsg'])); $timeStamp = time(); if(empty($likeMsg)) die('ERROR: Message is empty'); $sql = "INSERT INTO `likes` (like_message, timestamp) VALUES ('$likeMsg', $timeStamp)"; $result = mysql_query($sql, $link) or die('ERROR: ' . mysql_error()); echo mysql_insert_id(); mysql_close($link); ?> The problematic line is $likeMsg = mysql_real_escape_string(trim($_POST['likeMsg']));. It seems to just return an empty string, and in my database under the like_message column all I see is blank entries. If I remove mysql_real_escape_string() though, it works fine. Here's my jQuery code if it helps. $('#like').bind('keydown', function(e) { if(e.keyCode == 13) { var likeMessage = $('#changer p').html(); if(likeMessage) { $.ajax({ cache: false, url: 'like.php', type: 'POST', data: { likeMsg: likeMessage }, success: function(data) { $('#like').unbind(); writeLikeButton(data); } }); } else { $('#button_container').html(''); } } }); All this jQuery code works fine, I've tested it myself independently. Any help is greatly appreciated, thanks.

  • Declaration, allocation and assignment of an array of pointers to function pointers

    - by manneorama
    Hello Stack Overflow! This is my first post, so please be gentle. I've been playing around with C from time to time in the past. Now I've gotten to the point where I've started a real project (a 2D graphics engine using SDL, but that's irrelevant for the question), to be able to say that I have some real C experience. Yesterday, while working on the event system, I ran into a problem which I couldn't solve. There's this typedef, //the void parameter is really an SDL_Event*. //but that is irrelevant for this question. typedef void (*event_callback)(void); which specifies the signature of a function to be called on engine events. I want to be able to support multiple event_callbacks, so an array of these callbacks would be an idea, but do not want to limit the amount of callbacks, so I need some sort of dynamic allocation. This is where the problem arose. My first attempt went like this: //initial size of callback vector static const int initial_vecsize = 32; //our event callback vector static event_callback* vec = 0; //size static unsigned int vecsize = 0; void register_event_callback(event_callback func) { if (!vec) __engine_allocate_vec(vec); vec[vecsize++] = func; //error here! } static void __engine_allocate_vec(engine_callback* vec) { vec = (engine_callback*) malloc(sizeof(engine_callback*) * initial_vecsize); } First of all, I have omitted some error checking as well as the code that reallocates the callback vector when the number of callbacks exceed the vector size. However, when I run this code, the program crashes as described in the code. I'm guessing segmentation fault but I can't be sure since no output is given. I'm also guessing that the error comes from a somewhat flawed understanding on how to declare and allocate an array of pointers to function pointers. Please Stack Overflow, guide me.

  • What is your favorite API developer community site? And why? [closed]

    - by whatupwilly
    There are a lot of great sites out there that offer good documentation, tools, tips, best-practices, sample code, etc. for the API's they are publishing. A sample: http://apiwiki.twitter.com http://developer.netflix.com/ http://developers.facebook.com/ https://affiliate-program.amazon.com/gp/advertising/api/detail/main.html http://code.google.com/ http://remix.bestbuy.com/ http://www.flickr.com/services/api/misc.overview.html http://products.wolframalpha.com/api/webserviceapi.html There are some no-brainers that I think a good developer site should have: Hi level introduction Quick start guide API specific details - showing example request and responses Links to sample code and/or 3rd party libraries Developer registration (e.g. get an API key) Blog But what about some other things: Online-Forum or Msg Board vs. Google Group (or similar) Galleries/ShowCases - spotlighting great apps built on the API - who has done nice galleries? Community Wiki - How do people feel about letting the community have edit rights on API documentation pages Online testing tools (like Facebook has a lot of nice interactive tools to simulate request/responses) What are some packages that you would recommend to put this all together: pbwiki Google Group pages MediaWiki API vendor package such as Sonoa Systems that offers a customizable developer portal So, to summarize: What are some other great API developer portals out there What are some nice features you like on them Any recommendations on what to use to build these features out Thanks, Will Zappos.com Public API (soon to launch) Product Manager

  • Intermittent bug - IE6 showing file as text in browser, rather than as file download

    - by Richard Ev
    In an ASP.NET WebForms 2.0 site we are encountering an intermittent bug in IE6 whereby a file download attempt results in the contents of the being shown directly in the browser as text, rather than the file save dialog being displayed. Our application allows the user to download both PDF and CSV files. The code we're using is: HttpResponse response = HttpContext.Current.Response; response.Clear(); response.AddHeader("Content-Disposition", "attachment;filename=\"theFilename.pdf\""); response.ContentType = "application/pdf"; response.BinaryWrite(MethodThatReturnsFileContents()); response.End(); This is called from the code-behind click event handler of a button server control. Where are we going wrong with this approach? Edit Following James' answer to this posting, the code I'm using now looks like this: HttpResponse response = HttpContext.Current.Response; response.ClearHeaders(); // Setting cache to NoCache was recommended, but doing so results in a security // warning in IE6 //response.Cache.SetCacheability(HttpCacheability.NoCache); response.AppendHeader("Content-Disposition", "attachment; filename=\"theFilename.pdf\""); response.ContentType = "application/pdf"; response.BinaryWrite(MethodThatReturnsFileContents()); response.Flush(); response.End(); However, I don't believe that any of the changes made will fix the issue.

  • Is this a hole in dynamic binding in C# 4?

    - by Galilyou
    I've seen a very interesting post on Fabio Maulo's blog. Here's the code and the bug if you don't want to jump to the url. I defined a new generic class like so: public class TableStorageInitializer<TTableEntity> where TTableEntity : class, new() { public void Initialize() { InitializeInstance(new TTableEntity()); } public void InitializeInstance(dynamic entity) { entity.PartitionKey = Guid.NewGuid().ToString(); entity.RowKey = Guid.NewGuid().ToString(); } } Note that InitializeInstance accepts one parameter, which is of type dynamic. Now to test this class, I defined another class that is nested inside my main Program class like so: class Program { static void Main(string[] args) { TableStorageInitializer<MyClass> x = new TableStorageInitializer<MyClass>(); x.Initialize(); } private class MyClass { public string PartitionKey { get; set; } public string RowKey { get; set; } public DateTime Timestamp { get; set; } } } Note: the inner class "MyClass" is declared private. Now if i run this code I get a "Microsoft.CSharp.RuntimeBinder.RuntimeBinderException" on the line "entity.PartitionKey = Guide.NewGuid().ToString()". The interesting part, though is that the message of the exception says "Object doesn't contain a definition for PartitionKey". Also note that if you changed the modifier of the nested class to public, the code will execute with no problems. So what do you guys think is really happening under the hood? Please refer to any documentation -of course if this is documented anywhere- that you may find?

    I use the following code for printing the line number in Text widget. my $c=0; my $r=0; $txt = $mw-Text( -background ='white', -width=>400, -height=>300, -selectbackground => 'skyblue', -insertwidth => 5, -borderwidth =>3, -highlightcolor => 'blue', ### after visit -highlightbackground => 'red' , ### default before visit -xscrollcommand => sub { print"CHAT NO :",$c++; }, # Determines the callback used when the Text widget is scrolled horizontally. -yscrollcommand = sub { print"LINR NO:",$r++; }, # Determines the callback used when the Text widget is scrolled vertically. -padx = 5, -pady = 5, )- pack (); the above code is printing the line number and character no is ok. but I used in Scrolled widget that output is not printing. what is the problem in the following code how can I solve this? $txt = $mw-Scrolled('Text', -scrollbars = 'se', -background ='white', -width=>400, -height=>300, -insertwidth => 5, -borderwidth =>3, -highlightcolor => 'blue', ### after visit -highlightbackground => 'red' , ### default before visit -padx => 5, -pady => 5, -xscrollcommand => sub { print"CHAT NO :",$c++; }, # Determines the callback used when the Text widget is scrolled horizontally. -yscrollcommand => sub { print"LINR NO :",$r++; }, # Determines the callback used when the Text widget is scrolled vertically. )->pack();

  • Class design when working with dataset

    - by MC
    If you have to retrieve data from a database and bring this dataset to the client, and then allow the user to manipulate the data in various ways before updating the database again, what is a good class design for this if the data tables will not have a 1:1 relationship with the class objects? Here are some I came up with: Just manipulate the DataSet itself on the client and then send it back to the database as is. This will work though obviously the code will be very dirty and not well-structured. Same as #1, but wrap the dataset code around classes. What I mean is that you may have a class that takes a dataset or a datatable in its constructor, and then provides public methods and properties to simplify the code. Inside these methods and properties it will be reading or manipulating the dataset. To update the database afterwards will be easy because you already have the updated dataset. Get rid of the dataset entirely on the client, convert to objects, then convert back to a dataset when needing to update the database. Is there any good resources where I can find information on this?

  • Get more error information from unhandled error

    - by Andrew Simpson
    I am using C# in a desktop application. I am calling a DLL written in C that I do not have the source code for. Whenever I call this DLL I get an untrapped error which I trap in an UnhandledException event/delegate. The error is : object reference not set to an instance of an object But the stack trace is empty. When I Googled this the info back was that the error was being hanlded eleswhere and then rethrown. But this can only be in the DLL I do not have the source code for. So, is there anyway I can get more info about this error? This is my code... in program.cs... AppDomain.CurrentDomain.UnhandledException += new UnhandledExceptionEventHandler(CurrentDomain_UnhandledException); static void CurrentDomain_UnhandledException(object sender, UnhandledExceptionEventArgs e) { try { Exception _ex = (Exception)e.ExceptionObject; //the stact trace property is empty here.. } finally { Application.Exit(); } } My DLL... [DllImport("AutoSearchDevice.dll", EntryPoint = "Start", ExactSpelling = false, CallingConvention = CallingConvention.StdCall)] public static extern int Start(int ASD_HANDLE); An I call it like so: public static void AutoSearchStart() { try { Start(m_pASD); } catch (Exception ex) { } }
