• Daylight saving time - do and don'ts

  - by Oded

  I am hoping to make this question and the answers to it the definitive guide to dealing with daylight saving time, in particular for dealing with the actual change overs. Many systems are dependent on keeping accurate time, the problem is with changes to time due to daylight savings - moving the clock forward or backwards. For instance, one has business rules in an order taking system that depend on the time of the order - if the clock changes, the rules might not be as clear. How should the time of the order be persisted? There is of course an endless number of scenarios - this one is simply an illustrative one. How have you dealt with the daylight saving issue? What assumptions are part of your solution? (looking for context here) As important, if not more so: What did you try that did not work? Why did it not work? I would be interested in programming, OS, data persistence and other pertinent aspects of the issue. General answers are great, but I would also like to see details especially if they are only available on one platform.

• Error checking overkill?

  - by James

  What error checking do you do? What error checking is actually necessary? Do we really need to check if a file has saved successfully? Shouldn't it always work if it's tested and works ok from day one? I find myself error checking for every little thing, and most of the time if feels overkill. Things like checking to see if a file has been written to a file system successfully, checking to see if a database statement failed.......shouldn't these be things that either work or don't? How much error checking do you do? Are there elements of error checking that you leave out because you trust that it'll just work? I'm sure I remember reading somewhere something along the lines of "don't test for things that'll never really happen".....can't remember the source though. So should everything that could possibly fail be checked for failure? Or should we just trust those simpler operations? For example, if we can open a file, should we check to see if reading each line failed or not? Perhaps it depends on the context within the application or the application itself. It'd be interesting to hear what others do. Thanks, James.

• GlassFish Security Realm, Active Directory and Referral

  - by Allan Lykke Christensen

  I've setup up a Security Realm in Glassfish to authenticate against an Active Directory server. The configuration of the realm is as follows: Class Name: com.sun.enterprise.security.auth.realm.ldap.LDAPRealm JAAS context: ldapRealm Directory: ldap://172.16.76.10:389/ Base DN: dc=smallbusiness,dc=local search-filter: (&(objectClass=user)(sAMAccountName=%s)) group-search-filter: (&(objectClass=group)(member=%d)) search-bind-dn: cN=Administrator,CN=Users,dc=smallbusiness,dc=local search-bind-password: abcd1234! The realm is functional and I can log-in, but when ever I log in I get the following error in the log: SEC1106: Error during LDAP search with filter [(&(objectClass=group)(member=CN=Administrator,CN=Users,dc=smallbusiness,dc=local))]. SEC1000: Caught exception. javax.naming.PartialResultException: Unprocessed Continuation Reference(s); remaining name 'dc=smallbusiness,dc=local' at com.sun.jndi.ldap.LdapCtx.processReturnCode(LdapCtx.java:2820) .... .... ldaplm.searcherror While searching for a solution I found that it was recommended to add java.naming.referral=follow to the properties of the realm. However, after I add this it takes 20 minutes for GlassFish to authenticate against Active Directory. I suspect it is a DNS problem on the Active Directory server. The Active Directory server is a vanilla Windows Server 2003 setup in a Virtual Machine. Any help/recommendation is highly appreciated!

• How does symbol binding work for shared libraries in linux

  - by bbazso

  When compiling a cpp program with g++ -O0 I noticed that my binary does not contain the symbol for the empty string (basic_string): _S_empty_rep_storage When I do compile this same program with -O2 I notice that the aforementioned symbol is indeed contained within the binary as follows (using nm on the bin): 00000000006029a0 V _ZNSs4_Rep20_S_empty_rep_storageE@@GLIBCXX_3.4 My application uses several .so (dynamic libraries) and when my aplication loads I notice that several of these .so files bind as follows (I set LD_DEBUG=all and ran my program): 28596: binding file /home/bbazso/usr/local/lib/mydynamiclib.so [0] to /usr/lib64/libstdc++.so.6 [0]: normal symbol `_ZNSs4_Rep20_S_empty_rep_storageE' [GLIBCXX_3.4] 28596: binding file /home/bbazso/usr/local/lib/mydynamiclib.so [0] to /home/bbazso/workspace/mytestapplication [0]: normal symbol `_ZNSs4_Rep20_S_empty_rep_storageE' [GLIBCXX_3.4] 28596: binding file /home/bbazso/workspace/mytestapplication [0] to /usr/lib64/libstdc++.so.6 [0]: normal symbol `_ZNSs4_Rep20_S_empty_rep_storageE' [GLIBCXX_3.4]** But I also noticed that one of my .so only binds as follows: 28087: binding file /home/bbazso/usr/local/lib/anotherdynamiclib.so [0] to /usr/lib64/libstdc++.so.6 [0]: normal symbol `_ZNSs4_Rep20_S_empty_rep_storageE' [GLIBCXX_3.4] but never binds to the binary (mytestapplication) as shown above for the mydynamiclib.so. So I was wondering what this actually means? Does this mean that anotherdynamiclib.so will use a different symbol for the empty string above than the rest of the application? I guess what I'm really asking is how does symbol binding work in the context of the example above? Thanks!

• sharp architecture question

  - by csetzkorn

  I am trying to get my head around the sharp architecture and follow the tutorial. I am using this code: using Bla.Core; using System.Collections.Generic; using Bla.Core.DataInterfaces; using System.Web.Mvc; using SharpArch.Core; using SharpArch.Web; using Bla.Web; namespace Bla.Web.Controllers { public class UsersController { public UsersController(IUserRepository userRepository) { Check.Require(userRepository != null,"userRepository may not be null"); this.userRepository = userRepository; } public ActionResult ListStaffMembersMatching(string filter) { List<User> matchingUsers = userRepository.FindAllMatching(filter); return View("ListUsersMatchingFilter", matchingUsers); } private readonly IUserRepository userRepository; } } I get this error: The name 'View' does not exist in the current context I have used all the correct using statements and referenced the assemblies as far as I can see. The views live in Bla.Web in this architecture. Can anyone see the problem? Thanks. Christian

• How can i inject servletcontext in spring

  - by M.R.

  I need to write a junit test for a rather complex application which runs in a tomcat. I wrote a class which builds up my spring context. private static ApplicationContext springContext = null; springContext = new ClassPathXmlApplicationContext( new String[] {"beans"....}); In the application there is a call: public class myClass implements ServletContextAware { .... final String folder = servletContext.getRealPath("/example"); ... } which breaks everything, because the ServletContext is null. I have started to build a mock object: static ServletConfig servletConfigMock = createMock(ServletConfig.class); static ServletContext servletContextMock = createMock(ServletContext.class); @BeforeClass public static void setUpBeforeClass() throws Exception { expect(servletConfigMock.getServletContext()).andReturn(servletContextMock).anyTimes(); expect(servletContextMock.getRealPath("/example")).andReturn("...fulllpath").anyTimes(); replay(servletConfigMock); replay(servletContextMock); } Is there a simple methode to inject the ServletContext or to start the tomcat with a deployment descriptor at the runtime of the junit test? I am using: spring, maven, tomcat 6 and easymock for the mock objects.

• How do you unit test a method containing a LINQ expression?

  - by Phil.Wheeler

  I'm struggling to get my head around how to accommodate a mocked method that only accepts a Linq expression as its argument. Specifically, the repository I'm using has a First() method that looks like this: public T First(Expression<Func<T, bool>> expression) { return All().Where(expression).FirstOrDefault(); } The difficulty I'm encountering is with my MSpec tests, where I'm (probably incorrectly) trying to mock that call: public abstract class with_userprofile_repository { protected static Mock<IRepository<UserProfile>> repository; Establish context = () => { repository = new Mock<IRepository<UserProfile>>(); repository.Setup<UserProfile>(x => x.First(up => up.OpenID == @"http://testuser.myopenid.com")).Returns(GetDummyUser()); }; protected static UserProfile GetDummyUser() { UserProfile p = new UserProfile(); p.OpenID = @"http://testuser.myopenid.com"; p.FirstName = "Joe"; p.LastLogin = DateTime.Now.Date.AddDays(-7); p.LastName = "Bloggs"; p.Email = "[email protected]"; return p; } } I run into trouble because it's not enjoying the Linq expression: System.NotSupportedException: Expression up = (up.OpenID = "http://testuser.myopenid.com") is not supported. So how does one test these sorts of scenarios?

• Deriving an HTMLElement Object from jQuery Object

  - by Jasconius

  I'm doing a fairly exhaustive series of DOM manipulations where a few elements (specifically form elements) have some events. I am dynamically creating (actually cloning from a source element) several boxes and assigning a change() event to them. The change event executes, and within the context of the event, "this" is the HTML Element Object. What I need to do at this point however is determine a contact for this HTML Element Object. I have these objects stored already as jQuery entities in assorted arrays, but obviously [HTMLElement Object] != [Object Object] And the trick is that I cannot cast $(this) and make a valid comparison since that would create a new object and the pointer would be different. So... I've been banging my head against this for a while. In the past I've been able to circumvent this problem by doing an innerHTML comparison, but in this case the objects I am comparing are 100% identical, just there's lots of them. Therefore I need a solid comparison. This would be easy if I could somehow derive the HTMLElement object from my originating jQuery object. Thoughts, other ideas? Help. :(

• Add objects in relationship not work using MagicalRecord saveWithBlock

  - by yong ho

  The code to perform a save block: [MagicalRecord saveWithBlock:^(NSManagedObjectContext *localContext) { for (NSDictionary *stockDict in objects) { NSString *name = stockDict[@"name"]; Stock *stock = [Stock MR_createInContext:localContext]; stock.name = name; NSArray *categories = stockDict[@"categories"]; if ([categories count] > 0) { for (NSDictionary *categoryObject in categories) { NSString *categoryId = categoryObject[@"_id"]; NSPredicate *predicate = [NSPredicate predicateWithFormat:@"categoryId == %@", categoryId]; NSArray *matches = [StockCategory MR_findAllWithPredicate:predicate inContext:localContext]; NSLog(@"%@", matches); if ([matches count] > 0) { StockCategory *cat = [matches objectAtIndex:0]; [stock addCategoriesObject:cat]; } } } } } completion:^(BOOL success, NSError *error) { }]; The Stock Model: @class StockCategory; @interface Stock : NSManagedObject @property (nonatomic, retain) NSString * name; @property (nonatomic, retain) NSSet *categories; @end @interface Stock (CoreDataGeneratedAccessors) - (void)addCategoriesObject:(StockCategory *)value; - (void)removeCategoriesObject:(StockCategory *)value; - (void)addCategories:(NSSet *)values; - (void)removeCategories:(NSSet *)values; @end The json look like this: [ { "name": "iPad mini ", "categories": [ { "name": "iPad", "_id": "538c655fae9b3e1502fc5c9e", "__v": 0, "createdDate": "2014-06-02T11:51:59.433Z" } ], }, { "name": "iPad Air ", "categories": [ { "name": "iPad", "_id": "538c655fae9b3e1502fc5c9e", "__v": 0, "createdDate": "2014-06-02T11:51:59.433Z" } ], } ] Open the core data pro, You can see only stock with the name of "iPad air" has it's categories saved. I just can't figure out why. You can see in the saveWithBlock part, I first find in the context for the same _id as in json, and then add the category object in the relationship. It's working, but not all of them. Why is that?

• android bindservice

  - by mnish

  hi, I get null pointer exception at line mService.start() when i try to bind to an already started service. I do the same thing from different activity(where the service gets started) everythig goes right. All these activities are part of one application. What do you think I do wrong? public class RouteOnMap extends MapActivity{ private static final int NEW_LOCATION = 1; private static final int GPS_OFF = 2; private MapView mMapView; private ILocService mService; private boolean mServiceStarted; private boolean mBound; private Intent mServiceIntent; private double mLatitude, mLongitude; private ServiceConnection connection = new ServiceConnection() { public void onServiceConnected(ComponentName className, IBinder iservice) { mService = ILocService.Stub.asInterface(iservice); mBound = true; } public void onServiceDisconnected(ComponentName className) { mService = null; mBound = false; } }; public void onCreate(Bundle savedInstanceState){ super.onCreate(savedInstanceState); setContentView(R.layout.mapview); mMapView = (MapView) findViewById(R.id.mapview); mMapView.setBuiltInZoomControls(true); mServiceIntent = new Intent(); mLatitude = 0.0; mLongitude = 0.0; mBound = false; } @Override public void onStart(){ super.onStart(); mServiceIntent.setClass(this, LocationService.class); //startService(mServiceIntent); if(!mBound){ mBound = true; this.bindService(mServiceIntent, connection, Context.BIND_AUTO_CREATE); } } @Override public void onResume(){ super.onResume(); try { mService.start(); } catch (RemoteException e) { e.printStackTrace(); } } @Override public void onPause(){ super.onPause(); if(mBound){ this.unbindService(connection); } } @Override protected boolean isRouteDisplayed() { // TODO Auto-generated method stub return false; } }

• Parent Control Mouse Enter/Leave Events With Child Controls

  - by Paul Williams

  I have a C# .NET 2.0 WinForms app. My app has a control that is a container for two child controls: a label, and some kind of edit control. You can think of it like this, where the outer box is the parent control: +---------------------------------+ | [Label Control] [Edit Control] | +---------------------------------+ I am trying to do something when the mouse enters or leaves the parent control, but I don't care if the mouse moves into one of its children. I want a single flag to represent "the mouse is somewhere inside the parent or children" and "the mouse has moved outside of the parent control bounds". I've tried handling MouseEnter and MouseLeave on the parent and both child controls, but this means the action begins and ends multiple times as the mouse moves across the control. In other words, I get this: Parent.OnMouseEnter (start doing something) Parent.OnMouseLeave (stop) Child.OnMouseEnter (start doing something) Child.OnMouseLeave (stop) Parent.OnMouseEnter (start doing something) Parent.OnMouseLeave (stop) The intermediate OnMouseLeave events cause some undesired effects as whatever I'm doing gets started and then stopped. I want to avoid that. I don't want to capture the mouse as the parent gets the mouse over, because the child controls need their mouse events, and I want menu and other shortcut keys to work. Is there a way to do this inside the .NET framework? Or do I need to use a Windows mouse hook?

• XAML Binding to complex value objects

  - by Gus

  I have a complex value object class that has 1) a number or read-only properties; 2) a private constructor; and 3) a number of static singleton instance properties [so the properties of a ComplexValueObject never change and an individual value is instantiated once in the application's lifecycle]. public class ComplexValueClass { /* A number of read only properties */ private readonly string _propertyOne; public string PropertyOne { get { return _propertyOne; } } private readonly string _propertyTwo; public string PropertyTwo { get { return _propertyTwo; } } /* a private constructor */ private ComplexValueClass(string propertyOne, string propertyTwo) { _propertyOne = propertyOne; _propertyTwo = PropertyTwo; } /* a number of singleton instances */ private static ComplexValueClass _complexValueObjectOne; public static ComplexValueClass ComplexValueObjectOne { get { if (_complexValueObjectOne == null) { _complexValueObjectOne = new ComplexValueClass("string one", "string two"); } return _complexValueObjectOne; } } private static ComplexValueClass _complexValueObjectTwo; public static ComplexValueClass ComplexValueObjectTwo { get { if (_complexValueObjectTwo == null) { _complexValueObjectTwo = new ComplexValueClass("string three", "string four"); } return _complexValueObjectTwo; } } } I have a data context class that looks something like this: public class DataContextClass : INotifyPropertyChanged { private ComplexValueClass _complexValueClass; public ComplexValueClass ComplexValueObject { get { return _complexValueClass; } set { _complexValueClass = value; PropertyChanged(this, new PropertyChangedEventArgs("ComplexValueObject")); } } } I would like to write a XAML binding statement to a property on my complex value object that updates the UI whenever the entire complex value object changes. What is the best and/or most concise way of doing this? I have something like: <Object Value="{Binding ComplexValueObject.PropertyOne}" /> but the UI does not update when ComplexValueObject as a whole changes.

• CSS compilers and converting IE hacks to conditional css

  - by xckpd7

  Skip to bottom for question, but first, a little context. So I have been looking into CSS compilers (like Sass & Less) for a while, and have been really interested in them, not because they help me understand anything easier (I've been doing css for a couple of years now) but rather they cut down on cruft and help me see things easier. I recently have been looking into reliably implementing inline-block (and clearfix), which require lots of extraneous code & hacks. Now according to all the authorities in the field, I shouldn't put IE hacks in the same page I do my CSS in, I should make them conditional. But for me that is a really big hassle to go through and manage all this additional code, which is why I really like things like Less. Instead of applying unsemantic classes, you specify a mixin and apply it once, and you're all set. So I guess I got a little of the track (I wanted to explain my points) but bascially, I'm at the point where these CSS compilers are very useful for me, and allow me to abstract a lot of the cruft away, and reliably apply them once and then just compile it. I would like to have a way to be able to compile IE specific styles into their own conditional files (ala Less / Sass) so I don't have to deal with managing 2 files for no reason. Does anything like a script/applcation that runs and can make underscore / star hacks apart of their own file exist?

• "Cannot open user default database" error with "User Instance=True"

  - by Keith

  I have a desktop application that uses Sql user instancing. This is my connection string: "Data Source=.\SqlExpress; AttachDbFilename=C:\path\file.mdf; Integrated Security=True; User Instance=True; Connect Timeout=100;" My application creates this DB, downloads a load of data into it from a web service and then does a lot of actions with it. The problem comes when I attempt to re-open the connection. I get a SqlException: "Cannot open user default database. Login failed. Login failed for user 'myDomain\myusername'." This error makes no sense in this context - I have no default database. I'm logging in to an instance created just for the current application, running separately from SqlExpress. There's no other way to connect to this DB. If I start the SqlExpress service and connect to the default instance it won't be visible. It only exists for this application. The file on disk is locked by the SqlExpress instance service running under the application. if I stop the app and restart it the connection works first time, but fails on re-opening. If I just stop the app I can delete the .mdf files and begin again, but it still crashes when I re-open the connection. As my app started the instance running as me my current user should have access to every DB in the instance. This doesn't happen for other users of the same code, which suggests that it's a SQL config issue. Does anyone have any idea what causes this and how to work around it?

• MVC Areas - View not found

  - by user314827

  Hi, I have a project that is using MVC areas. The area has the entire project in it while the main "Views/Controllers/Models" folders outside the Areas are empty barring a dispatch controller I have setup that routes default incoming requests to the Home Controller in my area. This controller has one method as follows:- public ActionResult Index(string id) { return RedirectToAction("Index", "Home", new {area = "xyz"}); } I also have a default route setup to use this controller as follows:- routes.MapRoute( "Default", // Default route "{controller}/{action}/{id}", new { controller = "Dispatch", action = "Index", id = UrlParameter.Optional } ); Any default requests to my site are appropriately routed to the relevant area. The Area's "RegisterArea" method has a single route:- context.MapRoute( "xyz_default", "xyz/{controller}/{action}/{id}", new { action = "Index", id = UrlParameter.Optional } My area has multiple controllers with a lot of views. Any call to a specific view in these controller methods like "return View("blah"); renders the correct view. However whenever I try and return a view along with a model object passed in as a parameter I get the following error:- Server Error in '/DeveloperPortal' Application. The view 'blah' or its master was not found. The following locations were searched: ~/Views/Profile/blah.aspx ~/Views/Profile/blah.ascx ~/Views/Shared/blah.aspx ~/Views/Shared/blah.ascx It looks like whenever a model object is passed in as a param. to the "View()" method [e.g. return View("blah",obj) ] it searches for the view in the root of the project instead of in the area specific view folder. What am I missing here ? Thanks in advance.

• DataBinding the AJAX Control Toolkit's Rating Control

  - by Nevada

  I'm attempting to use the AJAX Control Toolkit's Rating control in a DataBinding scenario. I have a ReuseRating column in my database that is a tinyint. It can hold values 1 through 5. Every record in the table has the value set to 1 currently. If I do this in my ItemTemplate everything works fine. I get 1 star filled in on my rating control. <act:Rating ID="ReuseRatingRating" runat="server" CurrentRating='<%# Convert.ToInt16(Eval("ReuseRating")) %>' MaxRating="5" StarCssClass="ratingStar" WaitingStarCssClass="savedRatingStar" FilledStarCssClass="filledRatingStar" EmptyStarCssClass="emptyRatingStar" /> Now I want to DataBind this in my EditTemplate like so. <act:Rating ID="ReuseRatingRating" runat="server" CurrentRating='<%# Convert.ToInt16(Bind("ReuseRating")) %>' MaxRating="5" StarCssClass="ratingStar" WaitingStarCssClass="savedRatingStar" FilledStarCssClass="filledRatingStar" EmptyStarCssClass="emptyRatingStar" /> Note, that I changed my Eval to a Bind in the CurrentRating property. This throws the following error. CS0103: The name 'Bind' does not exist in the current context Can anyone help me out on this one? I've been knocking my head against the wall for a couple of hours now.

• Wrap CKEditor WYSYWG content with additional (non editable) HTML to apply element specific formattin

  - by Danlance

  I am attempting to have the WYSYWG view within CKEDITOR display with the same formatting as it will within the final rendered HTML. I am currently applying the correct CSS through specifying the contentsCss property when loading CKEditor. This works fine for some of the formatting, however a lot of the css formatting is applied to elements which will surround the edited HTML within the final rendered page - and so the WYSYWG view is not consistent with the final rendered view. I would like to be able to specify HTML code at runtime which will wrap the editable HTML content within the CKEditor WYSYWG view - but not have this be part of the editable code, or rendered within the HTML code. For instance, currently the HTML code surrounding the editable content is: <body spellcheck="false" class="cke_show_borders"> [Editable Content] </body> Where as in one particular instance I would it like it to render like this: <body spellcheck="false" class="cke_show_borders"><div id="container_everything"><div id="content_container"><div class="introduction_container"><div class="introduction_text"> [Editable Content] </div></div></div></div></body> I need to be able to specify different prefix and suffix code blocks at runtime, as specific HTML depends on the context of the element being edited. Can anyone point me in the right direction? Thanks.

• Help with editing data in entity framework.

  - by Levelbit

  Title of this question is simple because there is no an easy explanation for what I'm trying to ask you. I hope you'll understand in the end :). I have to tables in my database: Company and Location (relationship:one to many) and corresponding entity sets. In my wpf application I have some datagrid which I want to fill with locations and to be able to edit every row in separate window as some form of details view (so I don't want to edit my data in datagrid). I did this by accessing Location entity from selected row and creating a new Location entity and then I copy properties from original entity to newly created. Something like cloning the object. After editing if I press OK changed data is copied to original object back, and if I press Cancel nothing happens. Of course, you probably thinking I could use NoTracking option and AttachAsModified method as was mentioned as solution in some earlier questions(see:http://stackoverflow.com/questions/803022/changing-entities-in-the-entityframework) by Alex James, but lets say I had some problems about that and I have my own reasons for doing this. Finally, because navigation property(Company) of my location entity is assigned to newly created location object(during cloning) from some reason in object context additional object as copy of object I want to edit from datagrid is created without my will(similar problem :http://blogs.msdn.com/alexj/archive/2009/12/02/tip-47-how-fix-up-can-make-it-hard-to-change-relationships.aspx). So, when I do ObjectContext.SaveChanges it inserts additional row of data into my database table Location, the same as the one i wanted to edit. I read about sth like this, but I don't quite understand why is that and how to block or override this. I hope I was clear as I could. Please, solutions or some other ideas.

• What does the \- mean in the mvn dependency tree output

  - by Calm Storm

  Hi, I tried doing a mvn dependency:tree and I get a tree of dependencies. The output looks like below. I want to know what is the "-" symbol that is shown at times and the "+-" symbol for other dependencies (it doesnt seem to be the scope) My actual question is, My project depends on many modules which internally depends on many spring artifacts. There are a few version clashes. I want to upgrade all spring related libraries to say the latest one (2.6.x or above). What is the preferred way to do this? Should I declare all the deps spring-context, spring-support (and 10 other artifacts) in my pom.xml and point them to 2.6.x ? Is there any other better method ?

• WPF Grid Row / Column Sizing in Proportion to DesiredSize?

  - by sinibar

  I have two user controls arranged vertically in a grid, both of which can expand to be taller than the grid can accommodate. I've put them in each in a scrollviewer which functionally works. What I want though is to give them them space in proportion to the amount that they want at run time. So if there's 500 height available, the upper control wants 400 and the lower 600, the upper control would get 200 and the bottom 300. I have no idea at design time how much space each will want in proportion to the other, so using 1*, 2* etc. for row height won't work for me. I can hand-code run-time proportional sizing, but am I missing a simple trick in XAML that would get me what I want? Context is as follows (trimmed for brevity)... <Grid> <TabControl> <TabItem> <Grid> <Grid> <Grid.RowDefinitions> <RowDefinition Height="Auto"/> <RowDefinition Height="*"/> <RowDefinition Height="*"/> </Grid.RowDefinitions> <GroupBox Grid.Row="0" Header="Title Area" /> <ScrollViewer Grid.Row="1" VerticalScrollBarVisibility="Auto"> <UserControl /> </ScrollViewer> <ScrollViewer Grid.Row="2" VerticalScrollBarVisibility="Auto"> <UserControl /> </ScrollViewer> </Grid> </Grid> </TabItem> </TabControl> </Grid>
