• How can I display the users profile pic using the facebook graph api?

  - by kielie

  Hi, I would like to display the users profile picture inside of my applications canvas page, is there a way to do that using the graph api? I know I can do it using FBML but I would also like to pass the profile pic to a flash game I am making, so I would have to get the profile pic from the api and send it as a variable, here is the code I have thus far, $facebook = new Facebook(array( 'appId' => FACEBOOK_APP_ID, 'secret' => FACEBOOK_SECRET_KEY, 'cookie' => true, 'domain' => 'myurl/facebook-test' )); $session = $facebook->getSession(); $uid = $facebook->getUser(); $me = $facebook->api('/me'); $updated = date("l, F j, Y", strtotime($me['updated_time'])); echo "Hello " . $me['name'] . $me['picture'] . "<br />"; echo "<div style=\"background:url(images/bg.jpg); width:760px; height:630px;\">" . "You last updated your profile on " . $updated . "</div>" . "<br /> your uid is" . $uid; Thanx in advance!

• UIScrollview calling superviews layoutSubviews when scrolling?

  - by marchinram

  Hello, I added a UITableView as a subview to a custom UIView class I'm working on. However I noticed that whenever I scroll the table it calls my classes layoutSubviews. I'm pretty sure its the UIScrollview that the table is inheriting from which is actually doing this but wanted to know if there is a way to disable this functionality and if not why is it happening? I don't understand why when you scroll a scrollview it needs its superview to layout its subviews. Code: @implementation CustomView - (id)initWithFrame:(CGRect)frame { if ((self = [super initWithFrame:frame])) { self.clipsToBounds = YES; UITableView *tableView = [[UITableView alloc] initWithFrame:CGRectMake(0.0, 15.0, 436.0, 132.0) style:UITableViewStylePlain]; tableView.dataSource = self; tableView.delegate = self; tableView.separatorStyle = UITableViewCellSeparatorStyleNone; tableView.backgroundColor = [UIColor clearColor]; tableView.showsVerticalScrollIndicator = NO; tableView.contentInset = UIEdgeInsetsMake(kRowHeight, 0.0, kRowHeight, 0.0); tableView.tag = componentIndex; [self addSubview:tableView]; [tableView release]; } return self; } - (void)layoutSubviews { // This is called everytime I scroll the tableview } @end

• jquery image hover popup cant detect browser edge and change its direction

  - by Salman

  hi guys i am trying to implement jquery image hover popup but facing a problem when the popup is closer to browser edge it goes beyond its edge i want it to change its direction when it finds that space is not enough to show that popup, i have see this effect in many plugins where popups, tooltips and drop down menus change their direction if they are close to browser window edge can any one guide me in right direction here is the screen shot for reference http://img512.imageshack.us/img512/4990/browseredge.png here is the jquery hover code function imagePreview(){ /* CONFIG */ xOffset = 10; yOffset = 30; // these 2 variable determine popup's distance from the cursor // you might want to adjust to get the right result /* END CONFIG */ $("a.preview").hover(function(e){ this.t = this.title; this.title = ""; var c = (this.t != "") ?

• Image animation over CGContextDrawPDFPage

  - by BittenApple

  I'm modifying the QuartzDemo sample app from Apple. In QuartzViewController.m I have modifications (by DyingCactus) which replac the back button and add a method to handle the back button press as follows: -(void)viewDidLoad { // Add the QuartzView [scrollView addSubview:self.quartzView]; //add custom back button if this is the PDF view... if ([self.quartzView isKindOfClass:[QuartzPDFView class]]) { self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"QuartzDemo" style:UIBarButtonItemStyleBordered target:self action:@selector(myBackButtonHandler:)]; } } - (void)myBackButtonHandler:(id)sender { [self.quartzView setFrame:CGRectMake(150, -200, 100, 200)]; [UIView beginAnimations:nil context:nil]; [UIView setAnimationDelegate:self]; [UIView setAnimationDidStopSelector:@selector(animationDidStop:finished:context:)]; [UIView setAnimationDuration:1.0]; [self.quartzView setFrame:CGRectMake(150, 0, 100, 200)]; [UIView commitAnimations]; } - (void)animationDidStop:(NSString *)animationID finished:(NSNumber *)finished context:(void *)context { [self.navigationController popViewControllerAnimated:YES]; } I have a PNG image in resources folder called "bookmark.png" and would like to have that image animate as in animation in the example above. The image can be loaded in an UImageview or something and lets say that I have one called bookmark. How do I call that instead of self.quartzview in this part of code: [self.quartzView setFrame:CGRectMake(150, -200, 100, 200)]; [UIView beginAnimations:nil context:nil]; [UIView setAnimationDelegate:self]; [UIView setAnimationDidStopSelector:@selector(animationDidStop:finished:context:)]; [UIView setAnimationDuration:1.0]; [self.quartzView setFrame:CGRectMake(150, 0, 100, 200)]; [UIView commitAnimations];

• Updating Database from DataSet

  - by clawson

  I am having trouble updating my Database from my code using a DataSet. I'm using SQL Server 2008 and Visual Studio 2008. Here is what I've done so far. I have created a table in SQL Server called MyTable which has two columns: id nchar(10), and name nchar(50). I have then created a datasource in my VB.net project that consists of this table using the dataset wizard and called this dataset MyDataSet. I run the following code on a button click: Try Dim myDataSet As New MyDataSet Dim newRow As MyDataSet.MyTableRow = myDataSet.MyTable.NewMyTableRow newRow.id = "1" newRow.name = "Alpha" myDataSet.MyTable.AddMyTableRow(newRow) myDataSet.AcceptChanges() Catch ex As Exception MsgBox(ex.Message) End Try when I run this and check the rows in SQL Server it returns 0 rows What have I missed? How can I add these rows / save changes in a dataset to the database? I have seen other examples that use a TableAdapter but I don't think I want to do this, I think I should be able to achieve this just using a DataSet. Am I mistaken? Help is greatly appreciated!

• Remove parent of matched locator

  - by Ilan

  Is there a way to locate a node based child properties? I need to run a web.config transform to remove the 2nd <dependentAssembly in the following: <runtime> <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1"> <!-- Don't want to delete this one --> <dependentAssembly> <assemblyIdentity name="System.Web.Helpers" publicKeyToken="31bf3856ad364e35"/> <bindingRedirect oldVersion="1.0.0.0-2.0.0.0" newVersion="2.0.0.0"/> </dependentAssembly> <!-- This is the one I want to delete --> <dependentAssembly> <assemblyIdentity name="Microsoft.VisualStudio.Enterprise.AspNetHelper" publicKeyToken="b03f5f7f11d50a3a" culture="neutral"/> <codeBase version="11.0.0.0" href="file:///C:/Program%20Files%20(x86)/Microsoft%20Visual%20Studio%2011.0/Common7/IDE/PrivateAssemblies/Microsoft.VisualStudio.Enterprise.AspNetHelper.DLL"/> </dependentAssembly> </assemblyBinding> </runtime> Finding the <assemblyIdentity is easy enough, but I need to delete the parent <dependentAssembly (and <codeBase). If there was a "xdt:Transform="RemoveParent" this would do the trick, but AFAIK there isn't. Alternatively if there was a Locator I could use on the <dependentAssembly which would match children, then that could work too.

• How to use Java varargs with the GWT Javascript Native Interface? (aka, "GWT has no printf()")

  - by markerikson

  I'm trying to quickly learn GWT as part of a new project. I found out that GWT doesn't implement Java's String.format() function, so there's no printf()-like functionality. I knew that some printf() implementations exist for Javascript, so I figured I could paste one of those in as a GWT Javascript Native Interface function. I ran into problems, and decided I'd better make sure that the varargs values were being passed in correctly. That's where things got ugly. First, some example code: // From Java, call the JSNI function: test("sourceString", "params1", "params2", "params3"); .... public static native void test(Object... params) /*-{ // PROBLEM: this kills GWT! // alert(params.length); // returns "function" alert(typeof(params)); // returns "[Ljava.lang.Object;@b97ff1" alert(params); }-*/; The GWT docs state that "calling a varargs JavaScript method from Java will result in the callee receiving the arguments in an array". I figured that meant I could at least check params.length, but accessing that throws a JavascriptException wrapped in an UmbrellaException, with no real information. When I do "typeof(params)", it returns "function". As if that weren't odd enough, if I check the string value of params, it returns what appears to be a string version of a Java reference. So, I guess I'm asking a few different questions here: 1) How do GWT/JSNI varargs actually work, and do I need to do something special to pass in values? 2) What is actually going on here? 3) Is there any easier way to get printf()-style formatting in a GWT application?

• Can a WPF ComboBox display alternative text when its selection is null?

  - by Garth T Kidd

  G'day! I want my WPF ComboBox to display some alternative text when its data-bound selection is null. The view model has the expected properties: public ThingoSelectionViewModel : INotifyPropertyChanged { public ThingoSelectionViewModel(IProvideThingos) { this.Thingos = IProvideThingos.GetThingos(); } public ObservableCollection<Thingo> Thingos { get; set; } public Thingo SelectedThingo { get { return this.selectedThingo; } set { // set this.selectedThingo and raise the property change notification } // ... } The view has XAML binding to the view model in the expected way: <ComboBox x:Name="ComboboxDrive" SelectedItem="{Binding Path=SelectedThingo}" IsEditable="false" HorizontalAlignment="Left" MinWidth="100" IsReadOnly="false" Style="{StaticResource ComboboxStyle}" Grid.Column="1" Grid.Row="1" Margin="5" SelectedIndex="0"> <ComboBox.ItemsSource> <CompositeCollection> <ComboBoxItem IsEnabled="False">Select a thingo</ComboBoxItem> <CollectionContainer Collection="{Binding Source={StaticResource Thingos}}" /> </CompositeCollection> </ComboBox.ItemsSource> </ComboBox> The ComboBoxItem wedged into the top is a way to get an extra item at the top. It's pure chrome: the view model stays pure and simple. There's just one problem: the users want "Select a thingo" displayed whenever the ComboBox' selection is null. The users do not want a thingo selected by default. They want to see a message telling them to select a thingo. I'd like to avoid having to pollute the viewmodel with a ThingoWrapper class with a ToString method returning "Select a thingo" if its .ActualThingo property is null, wrapping each Thingo as I populate Thingos, and figuring out some way to prevent the user from selecting the nulled Thingo. Is there a way to display "Select a thingo" within the ComboBox' boundaries using pure XAML, or pure XAML and a few lines of code in the view's code-behind class?

• Cross-platform game development: ease of development vs security

  - by alcuadrado

  Hi, I'm a member and contributor of the Argentum Online (AO) community, the first MMORPG from Argentina, which is Free Software; which, although it's not 3D, it's really addictive and has some dozens of thousands of users. Really unluckily AO was developed in Visual Basic (yes, you can laugh) but the former community, so imagine, the code not only sucks, it has zero portability. I'm planning, with some friends to rewrite the client, and as a GNU/Linux frantic, want to do it cross-platform. Some other people is doing the same with the server in Java. So my biggest problem is that we would like to use a rapid development language (like Java, Ruby or Python) but the client would be pretty insecure. Ruby/Python version would have all it's code available, and the Java one would be easily decompilable (yes, we have some crackers in the community) We have consider the option to implement the security module in C/C++ as a dynamic library, but it can be replaced with a custom one, so it's not really secure. We are also considering the option of doing the core application in C++ and the GUI in Ruby/Python. But haven't analysed all it's implications yet. But we really don't want to code the entire game in C/C++ as it doesn't need that much performance (the game is played at 18fps on average) and we want to develop it as fast as possible. So what would you choose in my case? Thank you!

• Rendering PDF on WebPage

  - by Priyank

  Hi. We are trying to load a pdf file in web browser using pdfobject javascript api. Currently the size of the pdf's that we are trying to display is close to 10MBs. This creates a long delay in displaying a PDF on web page; while the complete PDF gets downloaded. We need to remove this lag by achieving either of the alternatives: Show a progress bar until the PDF is actually displayed. We couldn't find an event which is triggered and can be used to find out if pdf is visible now. This lacking doesn't let us decide when to stop showing progress bar/spinner OR lazy load the PDF such that it gets displayed as soon as first page gets loaded. With that ateast user will have a visual indication as to something is happening. We couldn'find anything in pdf object that lets us do a lazy load. User alternative pdf rendering api; this is a low priority as we already have complete code in place; but in an event of first 2 alternatives not being met; we'd have to consider this option. So please feel free to suggest. Any other ideas as to how user interaction can be made more intuitive or pleasant; would be welcome. Cheers

  I am using transaction replication with push subscription. I am developing a UI for replication using RMO in C#.NET between different instances of the same database within same machine holding similar schema and structure. I am using Single subscriber and multiple publisher topology. During creation of publication i want to set a few article properties such as Keep the existing object unchanged ,allow schema changes at subscriber to false a,copy foriegn key constarint and copy check constraints to true. How do i set the article properties using RMO in C# .NET. I am using Visual Studio 2008 SP1.I also want to know as how we can select all the objects including Tables,Views,Stored Procedures for publishing at one stretch. I could do it for one table but i want to select all the tables at one stretch. This is the code snippet i used for selecting single table for publishing. TransArticle ta = new TransArticle(); ta.Name = "Article_1"; ta.PublicationName = "TransReplication_DB2"; ta.DatabaseName = "DB2"; ta.SourceObjectName = "person"; ta.SourceObjectOwner = "dbo"; ta.ConnectionContext = conn; ta.Create();

• Problems with jQuery load and getJSON only when using Chrome

  - by leftend

  I'm having an issue with two jQuery calls. The first is a "load" that retrieves HTML and displays it on the page (it does include some Javascript and CSS in the code that is returned). The second is a "getJSON" that returns JSON - the JSON returned is valid. Everything works fine in every other browser I've tried - except Chrome for either Windows or Mac. The page in question is here: http://urbanistguide.com/category/Contemporary.aspx When you click on a Restaurant name in IE/FF, you should see that item expand with more info - and a map displayed to the right. However, if you do this in Chrome all you get is the JSON data printed to the screen. The first problem spot is when the "load" function is called here: var fulllisting = top.find(".listingfull"); fulllisting.load(href2, function() { fulllisting.append("<div style=\"width:99%;margin-top:10px;text-align:right;\"><a href=\"#\" class=\"" + obj.attr("id") + "\">X</a>"); itemId = fulllisting.find("a.listinglink").attr("id"); ... In the above code, the callback function doesn't seem to get invoked. The second problem spot is when the "getJSON" function is called: $.getJSON(href, function(data) { if (data.error.length > 0) { //display error message } else { ... } In this case - it just seems to follow the link instead of performing the callback... and yes, I am doing a "return false;" at the end of all of this to prevent the link from executing. All of the rest of the code is inline on that page if you want to view the source code. Any ideas?? Thanks

• C++ LNK2019 error with constructors and destructors in derived classes

• jQuery - Not sure which method to use, closest() and parent() don't work.

  - by Nike

  Hello, again. :) God i feel like i'm spamming stackoverflow, this is my 3rd post for today. Sorry, heh. I even posted a question regarding this before, kind of, but i've changed the code a bit since so i thought it was better to post a new question. $('.pmlist ul li h4 .toggle').click(function() { $(this).closest('.meddel').toggle(250); }); That's what i've got now. The reason why the closest() method isn't working is because the div .meddel is just next to the h4 element. And closest() only crawls right up the DOM tree, ignoring other child elements. Right? parent() works almost the same and doesn't work either. And as i only want to toggle the closest .meddel div in the element, i need something that, yeah justs grabs the nearest one, and not all of them. To clear it up a bit, here's the HTML for one list item: <li class="item"> <h4><a class="toggle">ämne</a><small>2010-04-17 kl 12:54 by <u>nike1</u></small></h4> <div class="meddel"> <span> <img style="max-width: 70%; min-height: 70%;" src="profile-images/nike1.jpg" alt="" /> <a href="account.php?usr=47">nike1</a> </span> <p>text</p> </div> </li> I have several items like that, and if i click one toggle link, i just want the nearest .meddel to be toggled, as mentioned before. Thanks. -Nike

• CSS absolute DIV causing other absolute DIV problems

  - by Tim

  Hello, I have implemented a chat script which requires an absolutely positioned DIV to be wrapped around the pages content. This is to ensure the chat windows stay at the bottom. The problem is that because of the absolute positioning of this main wrapper, all other absolutely positioned elements (eg. Jquery Auto-completes, datepicker's etc) now scroll up and down with the page. Here is an example of the HTML: <body> <div id="main_container"> <div id="content">Elements like Jquery Autocompletes, Datepickers with absolute positioned elements in here</div> </div> The DIV "main_container" style looks like this: #main_container { width:100%; background-color:#ffffff; /* DO NOT REMOVE THIS; or you'll have issue w/ the scrollbar, when the mouse pointer is on a white space */ overflow-x: hidden; overflow-y: scroll; height:100%; /* this will make sure that the height will extend at the bottom */ position:absolute; /* container div must be absolute, for our fixed bar to work */ } I hope there is a simple fix as the chat script is too good to get rid of. Thanks, Tim

• call/cc in Lua - Possible?

  - by Pessimist

  The Wikipedia article on Continuation says: "In any language which supports closures, it is possible to write programs in continuation passing style and manually implement call/cc." Either that is true and I need to know how to do it or it is not true and that statement needs to be corrected. If this is true, please show me how to implement call/cc in Lua because I can't see how. I think I'd be able to implement call/cc manually if Lua had the coroutine.clone function as explained here. If closures are not enough to implement call/cc then what else is needed? The text below is optional reading. P.S.: Lua has one-shot continuations with its coroutine table. A coroutine.clone function would allow me to clone it to call it multiple times, thus effectively making call/cc possible (unless I misunderstand call/cc). However that cloning function doesn't exist in Lua. Someone on the Lua IRC channel suggested that I use the Pluto library (it implements serialization) to marshal a coroutine, copy it and then unmarshal it and use it again. While that would probably work, I am more interested in the theoretical implementation of call/cc and in finding what is the actual minimum set of features that a language needs to have in order to allow for its manual implementation.

• How to display a subview loaded from a separate NIB file

  - by Marcus Netter

  I'm developing a Cocoa desktop application that uses a source list in the style of iTunes: different elements in the source list cause the main content area to display different views. The content area is entirely filled with a (vertical) NSSplitView; on the left is an NSOutlineView source list. When the user selects an item on the left, the relevant view appears on the right side of the splitter. I can make it work well enough by putting everything in one NIB file and putting a borderless NSTabView to the right of the splitter; to switch views, I just have to change the selected tab. But putting all the views in one NIB is bad practice, so I'm trying to move each of the subviews into their own NIB files. I have a pretty good idea of most of this process — I've created an NSViewController subclass for each of these views (EntityDetailViewController, GroupDetailViewController, and so on), set the File's Owner of each new NIB to the relevant controller class, set the view connection in each NIB, and reworked the bindings. What I don't know is how to actually change which subview is being shown on screen. I've tried using the default generic NSView on the right side and sending it addSubview: messages; I've tried connecting to it as the first subview and calling NSView *newSubview = /* get subview from the new subview controller */ [[subview superview] replaceSubview:subview with:newSubview]; [self setSubview:newSubview]; But everything just leaves the space blank. How do I display a subview loaded from a separate NIB?

• Overriding MSBuildExtensionsPath in the MSBuild task is flaky

  - by Stuart Lange

  This is already cross-posted at MS Connect: https://connect.microsoft.com/VisualStudio/feedback/details/560451 I am attempting to override the property $(MSBuildExtensionsPath) when building a solution containing a C# web application project via msbuild. I am doing this because a web application csproj file imports the file "$(MSBuildExtensionsPath)\Microsoft\VisualStudio\v9.0\WebApplications\Microsoft.WebApplication.targets". This file is installed by Visual Studio to the standard $(MSBuildExtensionsPath) location (C:\Program Files\MSBuild). I would like to eliminate the dependency on this file being installed on the machine (I would like to keep my build servers as "clean" as possible). In order to do this, I would like to include the Microsoft.WebApplication.targets in source control with my project, and then override $(MSBuildExtensionsPath) so that the csproj will import this included version of Microsoft.WebApplication.targets. This approach allows me to remove the dependency without requiring me to manually modify the web application csproj file. This scheme works fine when I build my solution file from the command line, supplying the custom value of $(MSBuildExtensionsPath) at the command line to msbuild via the /p flag. However, if I attempt to build the solution using the MSBuild task in a custom msbuild project file (overriding MSBuildExtensionsPath using the "Properties" attribute), it fails because the web app csproj file is attempting to import the Microsoft.WebApplication.targets from the "standard" Microsoft.WebApplication.targets location (C:\Program Files\MSBuild). Notably, if I run msbuild using the "Exec" task in my custom project file, it works. Even more notably, the FIRST time I run the build using the "MSBuild" task AFTER I have run the build using the "EXEC" task (or directly from the command line), the build works. Has anyone seen behavior like this before? Am I crazy? Is anyone aware of the root cause of this problem, a possible workaround, or whether this is a legitimate bug in MSBuild?

• Accessing deleted rows from a DataTable

  - by Ken

  Hello: I have a parent WinForm that has a MyDataTable _dt as a member. The MyDataTable type was created in the "typed dataset" designer tool in Visual Studio 2005 (MyDataTable inherits from DataTable) _dt gets populated from a db via ADO.NET. Based on changes from user interaction in the form, I delete a row from the table like so: _dt.FindBySomeKey(_someKey).Delete(); Later on, _dt is passed by value to a dialog form. From there, I need to scan through all the rows to build a string: foreach (myDataTableRow row in _dt) { sbFilter.Append("'" + row.info + "',"); } The problem is that upon doing this after a delete, the following exception is thrown: DeletedRowInaccessibleException: Deleted row information cannot be accessed through the row. The work around that I am currently using (which feels like a hack) is the following: foreach (myDataTableRow row in _dt) { if (row.RowState != DataRowState.Deleted && row.RowState != DataRowState.Detached) { sbFilter.Append("'" + row.info + "',"); } } My question: Is this the proper way to do this? Why would the foreach loop access rows that have been tagged via the Delete() method??

I've checked on my own machine and it does exist. I don't really want to start copying over files manually to the build server. Here's the line from the csproj file which is being imported to the proj file: <Import Project="$(MSBuildToolsPath)\Microsoft.CSharp.targets" /> <Import Project="$(MSBuildToolsPath)\SqlServer.targets" /> Here's the line from the proj file which is begin run by our Team City Server: <Import Project="..\$(ProjectName).csproj"/> My question is really: Where does this file comes from? Is it part of the Visual Studio install for example.. Or is there some re-distribution package somewhere to allow me to compile this project on our build server? Thanks BTW.. if i just copy the file onto the Build server it does actually work. Dave

• Question about registering COM server and Add Reference to it in a C# project

  - by smwikipedia

  I build a COM server in raw C++, here is the procedure: (1) write an IDL file to define the interface and library. (2) use msidl.exe to compile the IDL file to necessary .h, .c, .tlb files. (3) implement the COM server in C++ and build a .dll file. (4) add the following registry entris: [HKEY_CLASSES_ROOT\RawComCarLib.ComCar.1\CurVer] @="RawComCarLib.ComCar.1" ;CLSID [HKEY_CLASSES_ROOT\CLSID{6CC26343-167B-4CF2-9EDF-99368A62E91C}] @="RawComCarLib.ComCar.1" [HKEY_CLASSES_ROOT\CLSID{6CC26343-167B-4CF2-9EDF-99368A62E91C}\InprocServer32] @="D:\com\Project01.dll" [HKEY_CLASSES_ROOT\CLSID{6CC26343-167B-4CF2-9EDF-99368A62E91C}\ProgID] @="RawComCarLib.ComCar.1" [HKEY_CLASSES_ROOT\CLSID{6CC26343-167B-4CF2-9EDF-99368A62E91C}\TypeLib] @="{E5C0EE8F-8806-4FE3-BC0E-3A56CFB38BEE}" ;TypeLib [HKEY_CLASSES_ROOT\TypeLib{E5C0EE8F-8806-4FE3-BC0E-3A56CFB38BEE}] [HKEY_CLASSES_ROOT\TypeLib{E5C0EE8F-8806-4FE3-BC0E-3A56CFB38BEE}\1.0] @="Car Server Type Lib" [HKEY_CLASSES_ROOT\TypeLib{E5C0EE8F-8806-4FE3-BC0E-3A56CFB38BEE}\1.0\0] [HKEY_CLASSES_ROOT\TypeLib{E5C0EE8F-8806-4FE3-BC0E-3A56CFB38BEE}\1.0\0\win32] @="D:\com\Project01.tlb" [HKEY_CLASSES_ROOT\TypeLib{E5C0EE8F-8806-4FE3-BC0E-3A56CFB38BEE}\1.0\FLAGS] @="0" [HKEY_LOCAL_MACHINE\SOFTWARE\Classes\TypeLib{E5C0EE8F-8806-4FE3-BC0E-3A56CFB38BEE}\1.0\0\win32] @="C:\Windows\System32\msdatsrc.tlb" (5) I try to add reference to the COM by click the Add Reference in the C# project. (6) In the COM tab, I saw my "Car Server Type Lib", it's ok until now. I try to use the Object Browser to browse my COM lib, but the Visual Studio said "the following components could not be browsed", and I noticed that there's no new reference added to the list in the C# project Reference. I can use the tlbimp.exe to generate a interop.CarCom.dll, and then use the COM through this interop dll, but I want this interop assembly to be generated automatically when I just add reference to the COM. Could someone tell me what's wrong? Many thanks.

• Detecting Xml namespace fast

  - by Anna Tjsoken

  Hello there, This may be a very trivial problem I'm trying to solve, but I'm sure there's a better way of doing it. So please go easy on me. I have a bunch of XSD files that are internal to our application, we have about 20-30 Xml files that implement datasets based off those XSDs. Some Xml files are small (<100Kb), others are about 3-4Mb with a few being over 10Mb. I need to find a way of working out what namespace these Xml files are in order to provide (something like) intellisense based off the XSD. The implementation of this is not an issue - another developer has written the code for this. But I'm not sure the best (and fastest!) way of detecting the namespace is without the use of XmlDocument (which does a full parse). I'm using C# 3.5 and the documents come through as a Stream (some are remote files). All the files are *.xml (I can detect if it was extension based) but unfortunately the Xml namespace is the only way. Right now I've tried XmlDocument but I've found it to be innefficient and slow as the larger documents are awaiting to be parsed (even the 100Kb docs). public string GetNamespaceForDocument(Stream document); Something like the above is my method signature - overloads include string for "content". Would a RegEx (compiled) pattern be good? How does Visual Studio manage this so efficiently? Another college has told me to find a fast Xml parser in C/C++, parse the content and have a stub that gives back the namespace as its slower in .NET, is this a good idea?

• Should I store generated code in source control

  - by Ron Harlev

  This is a debate I'm taking a part in. I would like to get more opinions and points of view. We have some classes that are generated in build time to handle DB operations (in This specific case, with SubSonic, but I don't think it is very important for the question). The generation is set as a pre-build step in Visual Studio. So every time a developer (or the official build process) runs a build, these classes are generated, and then compiled into the project. Now some people are claiming, that having these classes saved in source control could cause confusion, in case the code you get, doesn't match what would have been generated in your own environment. I would like to have a way to trace back the history of the code, even if it is usually treated as a black box. Any arguments or counter arguments? UPDATE: I asked this question since I really believed there is one definitive answer. Looking at all the responses, I could say with high level of certainty, that there is no such answer. The decision should be made based on more than one parameter. Reading the answers below could provide a very good guideline to the types of questions you should be asking yourself when having to decide on this issue. I won't select an accepted answer at this point for the reasons mentioned above.
