  • Windows Server 2008: How to tell if a user is a 'local' use or a 'domain' user

    - by David
    I'm a developer, not a server admin, so please bear with me! I've been tasked with checking the installation of some software on a Windows Server 2008 R2 machine in the cloud, within two scenarios: There is no domain, the software will use local users and groups for authentication There is a domain, the software will use domain users and groups for authentication I've done part 1, but I'm puzzled about part 2. I've just installed the Active Directory Domain Services role on the server, so now I have a domain of one computer. When I look in Active Directory Users and Computers, I see all my original local users and groups. Have they now been 'promoted' to domain users? Or do I not have any domain users yet? Is there a way I can tell the difference between domain users and local users now? Thanks

  • How can I programatically convert SQL data-types to .Net data-types?

    - by Simon
    Can anyone show me a way of converting SQL Server data-types (varchar for example) to .Net data-types (String for example). I'm assuming that automatic conversion is not possible? I have an 'EntityProperty' object and would like it to have an appropriate 'Type' property (string, decimal, int32 etc), at the moment this property is just a string - 'int32' for example. A little background: I'm using SQL DMO in an internal code generation app to query a database and generate a stored procedure based DAL from the database. Being an internal app I can take quite a few shortcuts and make quite a few assumptions. To get the app working at the moment this data-type conversion is handled by a Select Case statement which just converts the types to strings and generates a set of properties based on these strings but I would prefer a little more flexibility in being able to handle the types (use of TypeOf etc). Anyone worked on something similar? I know EF, nHibernate, Subsonic etc could do all this for me but in this case, for various reasons, I am having to roll my own. :)

  • generated service mock: everything but RhinoMocks fails?

    - by hko
    I have the "quest" to search for the next Mocking Framework for my company, and basically it's down to NSubstitute (simplest syntax, but no strict mocks), FakeItEasy(best reviews, Roy Osherove bonus, and slightly better lib support than NSubstitute), Moq (best "other libs support", biggest featureset, downside: mock.Object). We definitely want to move on from RhinoMocks, e.g. because of the unusefull interactiontest error messages (it should tell me what the parameter was instead, when a verification fails). So I was pretty surprised the other day (that was yesterday) when I found out RhinoMocks could do a thing where every other mock framework fails at: Mocking an autogenerated SomethingService (a typical VS autogenerated service with a default construtor in a partial class). Please don't argue about the design.. I intend to write lightweight integration tests (and some unit tests), and I can't mess around with the service, the product is installed on too many customers system. See this code: // here the NSubstitute and FakeItEasy equivalents throw an exception.. see below TicketStoreService fakeTicketStoreService = MockRepository.GenerateMock<TicketStoreService>(); fakeTicketStoreService.Expect(service => service.DoSomething(Arg.Is(new Guid())).Return(new Guid()); fakeTicketStoreService.DoSomething(Arg.Is(new Guid())); fakeTicketStoreService.VerifyAllExpectations(); Note that DoSomething is a non-virtual methodcall in an autogenerated class. So it shouldn't work, according to common knowledge. But it does. Problem is that it's the only (non commercial) framework that can do this: Rhino.Mocks works, and verification works too FakeItEasy says it doesn't find a default constructor (probably just wrong exception message): No default constructor was found on the type SomeNamespace.TicketStoreService Moq gives something sane and understandable: Invalid setup on a non-virtual (overridable in VB) member: service=> service.DoSomething Nsubstitute gives a message System.NotSupportedException: Cannot serialize member System.ComponentModel.Component.Site of type System.ComponentModel.ISite because it is an interface. I'm really wondering what's going on here with the frameworks, except Moq. The "fancy new" frameworks seem to have an initial perf hit too, probably preparing some Type cache and serializing stuff, whilst RhinoMocks somehow manages to create a very "slim" mock without recursion. I have to admit I didn't like RhinoMocks very well, but here it shines.. unfortunately. So, is there a way to get that to work with newer (non-commercial!) mocking frameworks, or somehow get a sane error message out of Rhino.Mocks? And why can Rhino.Mocks achieve this, when clearly every Mocking framework states it can only work with virtual methods when given a concrete class? Let's not derail the discussion by talking about alternative approaches like Extract&Override or runtime-proxy Mocking frameworks like JustMock/TypeMock/Moles or the new Fakes framework, I know these, but that would be less ideal solutions, for reasons beyond this topic. Any help appreciated..

  • ASP.NET MVC - Disable Html Helper control using boolean value from Model

    - by The Matt
    I am outputting a textbox to the page using the Html helpers. I want to add the disabled attribute dynamically based on whether or not a boolean value in my model is true or false. My model has a method that returns a boolean value: <% =Model.IsMyTextboxEnabled() %> I currently render the textbox like follows, but I want to now enabled or disable it: <% =Html.TextBox("MyTextbox", Model.MyValuenew { id = "MyTextbox", @class = "MyClass" })%> If the return value of Model.IsMyTextboxEnabled() == true I want the following to be output: <input class="MyClass" id="MyTextbox" name="MyTextbox" type="text" value="" /> If it == false, I want it to output as: <input class="MyClass" id="MyTextbox" name="MyTextbox" type="text" value="" disabled /> What is the cleanest way to do this?

  • WCF reuse types in referenced assemblies does not reuse the ServiceContract Interface

    - by Matt
    I have three seperate projects: -MyUserControl (Needs a reference to a service implementing IMyService) -MyService (Implements IMyService) -MySharedInterfaces (IMyUserControl and IMyService) -MyWebApp The user control needs to be dynamically loaded at runtime. This implements IMyUserControl and has a property of type IMyService which will be set at runtime. The trouble is even with the option to reuse types the WebApp isn't reusing the IMyServiceType, it always generates it again from the Service Reference. This wouldn't be an issue if I could cast it to MySharedInterfaces.IMyService (which I can't understand, since it should be exactly the same). The user control is expecting something of type IMyService, is there anyway to either cast the WebServiceReference.IMyService back to MySharedInterface.IMyServiceReference or force the WebServiceReference to reuse the MySharedInterface.IMyServiceReference? Thanks

  • Activator.CreateInstance(string) and Activator.CreateInstance<T>() difference

    - by Juan Manuel Formoso
    No, this is not a question about generics. I have a Factory pattern with several classes with internal constructors (I don't want them being instantiated if not through the factory). My problem is that CreateInstance fails with a "No parameterless constructor defined for this object" error unless I pass "true" on the non-public parameter. Example // Fails Activator.CreateInstance(type); // Works Activator.CreateInstance(type, true); I wanted to make the factory generic to make it a little simpler, like this: public class GenericFactory<T> where T : MyAbstractType { public static T GetInstance() { return Activator.CreateInstance<T>(); } } However, I was unable to find how to pass that "true" parameter for it to accept non-public constructors (internal). Did I miss something or it isn't possible?

  • SQLite doesn't have booleans or date-times...but C# does

    - by DanM
    I've been thinking about using SQLite for my next project, but I'm concerned that it seems to lack proper datetime and bit data types. If I use DbLinq (or some other ORM) to generate C# classes, will the data types of the properties be "dumbed down"? Will date-time data be placed in properties of type string or double? Will boolean data be placed in properties of type int? If yes, what are the implications? I'm envisioning a scenario where I need to write a whole second layer of classes with more specific data types and do a bunch of transformations and casts, but maybe it's not so bad. If you have any experience with this or a similar scenario, what are your "lessons learned"?

  • Broadcast receiver, check status, turning off connection with F8

    - by yoann
    I am using eclipse with android sdk 3.2 I have some problems to make my broadcast receiver working when the connection is lost. first I have checked the type of network to make sure I understand well : ConnectivityManager manager = (ConnectivityManager) getSystemService(CONNECTIVITY_SERVICE); boolean is3g = manager.getNetworkInfo( ConnectivityManager.TYPE_MOBILE) .isConnectedOrConnecting(); boolean isWifi = manager.getNetworkInfo( ConnectivityManager.TYPE_WIFI) .isConnectedOrConnecting(); NetworkInfo info = manager.getActiveNetworkInfo(); if (info != null) Toast.makeText(getApplicationContext(), info.getTypeName(), Toast.LENGTH_LONG).show(); else Toast.makeText(getApplicationContext(), "Pas de connexion", Toast.LENGTH_LONG).show(); if (!is3g) Log.i("Network Listener", "DISCONNECTED"); else Log.i("Network Listener", "CONNECTED"); == this is a mobile network, I'm connected Then I press F8 or I make : telnet localhost 5554 gsm data off to stop the connection Here is my dynamic broadcast receiver in an activity : public class ActivityA extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.query); this.registerReceiver(this.networkStateReceiver, new IntentFilter( ConnectivityManager.CONNECTIVITY_ACTION)); } BroadcastReceiver networkStateReceiver = new BroadcastReceiver() { @Override public void onReceive(Context context, Intent intent) { ConnectivityManager connMgr = (ConnectivityManager) context .getSystemService(Context.CONNECTIVITY_SERVICE); NetworkInfo networkInfo = connMgr.getActiveNetworkInfo(); //i have tried several things : State networkState = networkInfo.getState(); // if (networkState.compareTo(State.DISCONNECTED) == 0) ... if (networkInfo != null && networkInfo.isConnected()) { Toast.makeText(getApplicationContext(), "CONNECTED", Toast.LENGTH_LONG).show(); Log.i("Network Listener", "Connected"); } else { Toast.makeText(getApplicationContext(), "DISCONNECTED", Toast.LENGTH_LONG).show(); Log.i("Network Listener", "Network Type Changed"); Intent offline = new Intent(AccountInfoActivity.this, OfflineWorkService.class); startService(offline); } }; My manifest : <uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/> The problem is : when the activityA is launched, my broadcast receive something and it displays "Connected"(Log) and my toast. When I turn off the connection manually, nothing happend. My service is not started, log message are not displayed, only toast messages work ... And even better, when I turn on the connection again (by pressing F8), I test again the type of connection, Toast messages are shown but this time Log messages don't work. Problems happend when I press F8. Anyway, I think I miss something with broadcast receivers, it's not totally clear. Please help me.

  • Haskell Syntax: Parse Error On Input

    - by NuNu
    As part of a mini-haskell compiler that I'm writing, I have a function named app. What I want this function to do is take in these arguments epp (App e1 e2). The first step would be to evaluate e1 recursively (epp e1) and check if the output would be an error. If not then evaluate e2 and then call another function eppVals to evaluate the outputs of the calls on e1 and e2 which I defined as v1 and v2 respectively. epp (App e1 e2) | epp e1 /= Error = eppVals v1 v2 | otherwise = Error where v1 = epp e1 v2 = epp e2 <- parse error on input `=' Logically I believe what I have written so far works but I'm getting a parse error on input = where I stated above. Any idea why? My second try epp :: Exp -> Error Val epp (App e1 e2) = (eppVals v1 v2) where v1 = (epp e1) v2 = (epp e2) But now throws Couldn't match expected type Val with actual type Error Val

  • Double pointer const-correctness warnings in C

    - by Michael Koval
    You can obviously cast a pointer to non-const data to a a pointer of the same type to const data: int *x = NULL; int const *y = x; Adding additional const qualifiers to match the additional indirection should logically work the same way: int * *x = NULL; int *const *y = x; /* okay */ int const *const *z = y; /* warning */ Compiling this with GCC or Clang with the -Wall flag, however, results in the following warning: test.c:4:23: warning: initializing 'int const *const *' with an expression of type 'int *const *' discards qualifiers in nested pointer types int const *const *z = y; /* warning */ ^ ~ Why does adding an additional const qualifier "discard qualifiers in nested pointer types"?

  • HttpURLConnection does not read the whole respnse

    I use HttpURLConnection to do HTTP POST but I dont always get back the full response. I wanted to debug the problem, but when I step through each line it worked.

  • InvalidOperationException When XML Serializing Inherited Class

    - by Nick
    I am having an issue serializing a c# class to an XML file that has a base class... here is a simple example: namespace Domain { [Serializable] public class ClassA { public virtual int MyProperty { get; set; } } } namespace Derived { public class ClassA : Domain.ClassA { public override int MyProperty { get { return 1; } set { /* Do Nothing */ } } } } When I attempt to serialize an instance of Derived.ClassA, I receive the following exception: InvalidOperationException(Types 'Domain.ClassA' and 'Derived.ClassA' both use the XML type name 'ClassA', from the namespace ". Use XML attributes to specify a unique XML name and/or namespace for the type.) The problem is that I want to create a single base class that simply defines the structure of the XML file, and then allow anyone else to derive from that class to insert business rules, but that the formatting will come through from the base. Is this possible, and if so, how do I attribute the base class to allow this?

    Here's the php script I'm using on a linux environment: <?php include("../_inc/odbcw.php"); //connect string $cat = $_GET["cat"]; if($_GET["st"]){$crs_query = "select crs_no, title, credits, abstr, prereq, coreq, lab_fee from xxx where active = 'Y' and cat = '".$cat."' and spec_top = 'Y' and prog='UNDG' order by crs_no";} else {$crs_query = "select crs_no, title, credits, abstr, prereq, coreq, lab_fee from xxx where active = 'Y' and cat = '".$cat."' and prog='UNDG' order by crs_no";} $crs_result = @mysql_query($crs_query); header("Content-type: application/vnd.ms-word"); header("Content-Disposition: attachment;Filename=cat.doc"); echo "<html>"; echo "<meta http-equiv=\"Content-Type\" content=\"text/html; charset=Windows-1252\">"; echo "<body>"; echo '<table border=0 width = 700>'; if($_GET["st"]){echo '<tr><td><font face=arial size=2><center>CATALOGUE<br>COURSE DESCRIPTIONS - '.$cat.'<br>SPECIAL TOPICS</center></font></td></tr>';} else {echo '<tr><td><font face=arial size=2><center>CATALOGUE<br>COURSE DESCRIPTIONS - '.$cat.'</center></font></td></tr>';} echo '</table>'; echo '<hr width=700>'; while($row = mysql_fetch_array($crs_result)) { $crs_no = $row['crs_no']; $title = $row['title']; $credits = $row['credits']; $abstr = $row['abstr']; $prereq = $row['prereq']; $coreq = $row['coreq']; $lab_fee = $row['lab_fee']; $rowspan = 2; if($prereq) {$rowspan++;} if($coreq) {$rowspan++;} if($lab_fee=="Y") {$rowspan++;} echo "<table border=0 width = 700>"; echo "<tr>"; echo "<td rowspan=".$rowspan." valign=top width=100><font face=arial size=2>".$crs_no."</font></td>"; echo "<td valign=top><font face=arial size=2><u>".$title."</u></font></td> <td valign=top align=right><font face=arial size=2>".$credits."</font></td>"; echo "</tr>"; echo "<tr>"; echo "<td colspan=2 valign=top align=justify><font face=arial size=2>".$abstr."</font></td>"; echo "</tr>"; if($prereq) { echo "<tr>"; echo "<td colspan=2 valign=top><font face=arial size=2>Prerequisite: ".$prereq."</font></td>"; echo "</tr>"; } if($coreq) { echo "<tr>"; echo "<td colspan=2 valign=top><font face=arial size=2>Coerequisite: ".$coreq."</font></td>"; echo "</tr>"; } if($lab_fee=="Y") { echo "<tr>"; echo "<td colspan=2 valign=top><font face=arial size=2>Lab Fee Required</font></td>"; echo "</tr>"; } echo "</table>"; echo "<br>"; } echo "</body>"; echo "</html>"; ?> Everything works fine before the inclusion of: header("Content-type: application/vnd.ms-word"); header("Content-Disposition: attachment;Filename=cat.doc"); echo "<html>"; echo "<meta http-equiv=\"Content-Type\" content=\"text/html; charset=Windows-1252\">"; echo "<body>"; These lines successfully bring up the dialogue box to open or save cat.doc, but after I open it, the only lines printed are: CATALOGUE COURSE DESCRIPTIONS - and the <HR> beneath this echoed text. It seems to go on lunch break for the while loop echoing section. Any ideas?

  • Why can't I access a particular website even though the server appears to be available

    - by 50ndr33
    I can't access http://www.lynda.com/ with any of my browsers on my home network. By checking http://www.downforeveryoneorjustme.com/, I can see that the server is up and I can access it via a proxy like TOR. This screen appears immediately after I type the page in It doesn't even try to load the page, it seems. Though when I ping the server I get this: I tried to do ipconfig /flushdns. But it didn't help either. Anyone know how to fix this?

  • Visual Studio 2010 Formatting

    - by Rosarch
    I have plenty of experience with Eclipse, and now I'm trying out Visual Studio 2010. I find its formatting somewhat counter-intuitive. Here are some things I'm trying to figure out: Is there a way to select all text and format/indent it properly, like SHIFT+A SHIFT+I in Eclipse? Why is it that when I type a line like if (n == 0) {, as soon as I type the opening brace, the text cursor is moved to the beginning of the line? Is this some productivity speedup I'm failing to see? When I hit ENTER after the aforementioned line, I'd like the closing brace to be put in place automatically for me. How can I do this? I've looked for hotkey documentation, and it's helped a bit, but this still feels clunky to me.

  • idiomatic property changed notification in scala?

    - by Jeremy Bell
    I'm trying to find a cleaner alternative (that is idiomatic to Scala) to the kind of thing you see with data-binding in WPF/silverlight data-binding - that is, implementing INotifyPropertyChanged. First, some background: In .Net WPF or silverlight applications, you have the concept of two-way data-binding (that is, binding the value of some element of the UI to a .net property of the DataContext in such a way that changes to the UI element affect the property, and vise versa. One way to enable this is to implement the INotifyPropertyChanged interface in your DataContext. Unfortunately, this introduces a lot of boilerplate code for any property you add to the "ModelView" type. Here is how it might look in Scala: trait IDrawable extends INotifyPropertyChanged { protected var drawOrder : Int = 0 def DrawOrder : Int = drawOrder def DrawOrder_=(value : Int) { if(drawOrder != value) { drawOrder = value OnPropertyChanged("DrawOrder") } } protected var visible : Boolean = true def Visible : Boolean = visible def Visible_=(value: Boolean) = { if(visible != value) { visible = value OnPropertyChanged("Visible") } } def Mutate() : Unit = { if(Visible) { DrawOrder += 1 // Should trigger the PropertyChanged "Event" of INotifyPropertyChanged trait } } } For the sake of space, let's assume the INotifyPropertyChanged type is a trait that manages a list of callbacks of type (AnyRef, String) = Unit, and that OnPropertyChanged is a method that invokes all those callbacks, passing "this" as the AnyRef, and the passed-in String). This would just be an event in C#. You can immediately see the problem: that's a ton of boilerplate code for just two properties. I've always wanted to write something like this instead: trait IDrawable { val Visible = new ObservableProperty[Boolean]('Visible, true) val DrawOrder = new ObservableProperty[Int]('DrawOrder, 0) def Mutate() : Unit = { if(Visible) { DrawOrder += 1 // Should trigger the PropertyChanged "Event" of ObservableProperty class } } } I know that I can easily write it like this, if ObservableProperty[T] has Value/Value_= methods (this is the method I'm using now): trait IDrawable { // on a side note, is there some way to get a Symbol representing the Visible field // on the following line, instead of hard-coding it in the ObservableProperty // constructor? val Visible = new ObservableProperty[Boolean]('Visible, true) val DrawOrder = new ObservableProperty[Int]('DrawOrder, 0) def Mutate() : Unit = { if(Visible.Value) { DrawOrder.Value += 1 } } } // given this implementation of ObservableProperty[T] in my library // note: IEvent, Event, and EventArgs are classes in my library for // handling lists of callbacks - they work similarly to events in C# class PropertyChangedEventArgs(val PropertyName: Symbol) extends EventArgs("") class ObservableProperty[T](val PropertyName: Symbol, private var value: T) { protected val propertyChanged = new Event[PropertyChangedEventArgs] def PropertyChanged: IEvent[PropertyChangedEventArgs] = propertyChanged def Value = value; def Value_=(value: T) { if(this.value != value) { this.value = value propertyChanged(this, new PropertyChangedEventArgs(PropertyName)) } } } But is there any way to implement the first version using implicits or some other feature/idiom of Scala to make ObservableProperty instances function as if they were regular "properties" in scala, without needing to call the Value methods? The only other thing I can think of is something like this, which is more verbose than either of the above two versions, but is still less verbose than the original: trait IDrawable { private val visible = new ObservableProperty[Boolean]('Visible, false) def Visible = visible.Value def Visible_=(value: Boolean): Unit = { visible.Value = value } private val drawOrder = new ObservableProperty[Int]('DrawOrder, 0) def DrawOrder = drawOrder.Value def DrawOrder_=(value: Int): Unit = { drawOrder.Value = value } def Mutate() : Unit = { if(Visible) { DrawOrder += 1 } } }
