  • SQL Server Column Level Encryption - Rotating Keys

    - by BarDev
    We are thinking about using SQL Server Column (cell) Level Encryption for sensitive data. There should be no problem when we initially encryption the column, but we have requirements that every year the Encryption Key needs to change. It seems that this requirement may be problem. Assumption: The table that includes the column that has sensitive data will have 500 million records. Below are the steps we have thought about implementing. During the encryption/decryption process is the data online, and also how long would this process take? Initially encrypt the column New Year Decrypt the column Encrypt the column with new key. Question : When the column is being decrypted/encrypted is the data online (available to be query)? Does SQL Server provide feature that allows for key changes while the data is online? BarDev

  • Encrypt remote linux server

    - by Margaret Thorpe
    One of my customers has requested that their web server is encrypted to prevent offline attacks to highly sensitive data contained in a mysql database and also /var/log. I have full root access to the dedicated server at a popular host. I am considering 3 options - FDE - This would be ideal, but with only remote access (no console) I imagine this would be very complex. Xen - installing XEN and moving their server within a XEN virtual machine and encrypting the VM - which seems easier to do remotely. Parition - encrypt the non-static partitions where the sensitive data resides e.g. /var /home etc. What would be the simplist approach that satisfies the requirements?

  • How to effectively secure a dedicated server for intranet use?

    - by Mark
    I need to secure a dedicated server for intranet use, the server is managed so will have software based security, but what other security should be considered for enterprise level security? The intranet is a host for an ECM (Alfresco) managing and storing sensitive documents. As the information is sensitive we are trying to make it as secure as reasonably possible (requirement in UK law). We plan to encrypt the data on the database. It will be connected to via SSL encryption. Should we consider Hardware firewall, Private lan between the application server and database server?

  • WPF ContextMenu with bound items: Items.Count == 0 in ContextMenuOpening event

    - by OregonGhost
    I have a ContextMenu with the ItemsSource bound to the selected item of a list view, like this: <ContextMenu ItemsSource="{Binding Path=PlacementTarget.SelectedItem, RelativeSource={RelativeSource Self}, Converter={StaticResource possibleConverter}}"/> The possibleConverter enumerates all possible values for a property of the the selected item, which are shown in the context menu. In the Opened event of the context menu, I select the current value like this: var cm = e.OriginalSource as ContextMenu; if (cm != null) { var lv = cm.PlacementTarget as ListView; var field = lv.SelectedItem as Field; var item = cm.ItemContainerGenerator.ContainerFromItem(cm.Items.OfType<object>().Where(o => o.ToString().Equals(field.StringValue)).FirstOrDefault()) as MenuItem; if (item != null) { item.IsChecked = true; } } Not particularly elegant, but it works. With the debugger I verified that the ContextMenu.Items.Count property has a non-zero value when expected (i.e. cm.Items.Count is non-zero in the if). So far, so good. There are, however, items in the listview where the context menu will have no items. In this case, an empty menu is shown. I tried to suppress this in the ContextMenuOpening event in the list view, like this: var lv = sender as ListView; if (lv != null) { var cm = lv.ContextMenu; if ((cm != null) && (cm.Items.Count > 0)) { // Here we want to check the current item, which is currently done in the Opened event. } else { e.Handled = true; } } Seems like it should work. However, cm.Items.Count is always zero. This is true even if ListView.SelectedItem did not change: For an item with menu entries, the menu is shown correctly after the first click, so the data binding has already happend. It is shown correct the second time as well, but in any case, Items.Count is zero in the ContextMenuOpening event. What am I missing? How can I suppress empty context menus? Why is the count zero in the ContextMenuOpening handler, which is in Windows Forms (ContextMenuStrip.Opening) the canonical point where to do these things? EDIT: Upon further investigating, it turns out that in the ContextMenuOpening handler, any binding to the listview fails, which is why ItemsSource is null. I tried to bind via ElementName, via a FindAncestor relationship, all to no avail. The PlacementTarget is null during that event. An ugly hack worked though: In the ContextMenuOpening event, I assign the list view to the ContextMenu.Tag property, while the ItemsSource binding now binds to Tag.SelectedItem. This updates the binding, so Items.Count is what it should be. It's still strange. How can you do meaningful things in ContextMenuOpening other than replacing the menu or something, if the binding fails because somehow the context menu is out of context during the event? Was it only tested with static pre-defined menu items?

  • Trouble determining proper decoding of a REST response from an ArcGIS REST service using IHttpModule

    - by Ryan Taylor
    First a little background on what I am trying to achieve. I have an application that is utilizing REST services served by ArcGIS Server and IIS7. The REST services return data in one of several different formats. I am requesting a JSON response. I want to be able to modify the response (remove or add parameters) before the response is sent to the client. However, I am having difficulty converting the stream to a string that I can modify. To that end, I have implemented the following code in order to try to inspect the stream. SecureModule.cs using System; using System.Web; namespace SecureModuleTest { public class SecureModule : IHttpModule { public void Init(HttpApplication context) { context.BeginRequest += new EventHandler(OnBeginRequest); } public void Dispose() { } public void OnBeginRequest(object sender, EventArgs e) { HttpApplication application = (HttpApplication) sender; HttpContext context = application.Context; HttpRequest request = context.Request; HttpResponse response = context.Response; response.Filter = new ServicesFilter(response.Filter); } } } ServicesFilter.cs using System; using System.IO; using System.Text; namespace SecureModuleTest { class ServicesFilter : MemoryStream { private readonly Stream _outputStream; private StringBuilder _content; public ServicesFilter(Stream output) { _outputStream = output; _content = new StringBuilder(); } public override void Write(byte[] buffer, int offset, int count) { _content.Append(Encoding.UTF8.GetString(buffer, offset, count)); using (TextWriter textWriter = new StreamWriter(@"C:\temp\content.txt", true)) { textWriter.WriteLine(String.Format("Buffer: {0}", _content.ToString())); textWriter.WriteLine(String.Format("Length: {0}", buffer.Length)); textWriter.WriteLine(String.Format("Offset: {0}", offset)); textWriter.WriteLine(String.Format("Count: {0}", count)); textWriter.WriteLine(""); textWriter.Close(); } // Modify response _outputStream.Write(buffer, offset, count); } } } The module is installed in the /ArcGIS/rest/ virtual directory and is executed via the following GET request. http://localhost/ArcGIS/rest/services/?f=json&pretty=true The web page displays the expected response, however, the text file tells a very different (encoded?) story. Expect Response {"currentVersion" : "10.0", "folders" : [], "services" : [ ] } Text File Contents Buffer: ? ?`I?%&/m?{J?J??t??`$?@??????iG#)?*??eVe]f@????{???{???;?N'????\fdl??J??!????~|?"~?G?u]???'?)??G?????G??7N????W??{?????,??|?OR????q?

How might I decode, unzip, and otherwise convert the byte stream into the string I know it should be for modification by my filter?

  • VS2010 Assembly Load Error

    - by Nate
    I am getting the following error when I try to build an ASP.NET 4 project in Visual Studio 2010: "Could not load file or assembly 'file:///C:\Dev\project\trunk\bin\Elmah.dll' or one of its dependencies. Operation is not supported. (Exception from HRESULT: 0x80131515)". I have verified that the dll does, in fact, exist, and is getting copied to the bin folder correctly. I have also tried removing and then re-adding the reference to the project. The build only fails when I switch the Solution Configuration to "Release". It does not fail when the Solution Configuration is set to "Debug". The only difference between the two configurations (that I know of) is shown in the following Web.config transform, Web.Release.config: <?xml version="1.0"?> <configuration xmlns:xdt="http://schemas.microsoft.com/XML-Document-Transform"> <connectionStrings> <add name="SqlServer" connectionString="" providerName="System.Data.SqlClient" xdt:Transform="SetAttributes" xdt:Locator="Match(name)"/> </connectionStrings> <system.web> <compilation xdt:Transform="RemoveAttributes(debug)" /> <customErrors mode="On" xdt:Transform="Replace"> <error statusCode="404" redirect="lost.htm" /> <error statusCode="500" redirect="uhoh.htm" /> </customErrors> </system.web> </configuration> I have tried using Fusion Log Viewer to track down the assembly binding issue, but it looks like it is finding and loading the assembly correctly. Here is the log: *** Assembly Binder Log Entry (6/8/2010 @ 10:01:54 AM) *** The operation was successful. Bind result: hr = 0x0. The operation completed successfully.

  • [Android] Launching activity from widget

    - by Steve H
    Hi, I'm trying to do something which really ought to be quite easy, but it's driving me crazy. I'm trying to launch an activity when a home screen widget is pressed, such as a configuration activity for the widget. I think I've followed word for word the tutorial on the Android Developers website, and even a few unofficial tutorials as well, but I must be missing something important as it doesn't work. Here is the code: public class VolumeChangerWidget extends AppWidgetProvider { public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds){ final int N = appWidgetIds.length; for (int i=0; i < N; i++) { int appWidgetId = appWidgetIds[i]; Log.d("Steve", "Running for appWidgetId " + appWidgetId); Toast.makeText(context, "Hello from onUpdate", Toast.LENGTH_SHORT); Log.d("Steve", "After the toast line"); Intent intent = new Intent(context, WidgetTest.class); PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0); RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.widget); views.setOnClickPendingIntent(R.id.button, pendingIntent); appWidgetManager.updateAppWidget(appWidgetId, views); } } } When adding the widget to the homescreen, Logcat shows the two debugging lines, though not the Toast. (Any ideas why not?) However, more vexing is that when I then click on the button with the PendingIntent associated with it, nothing happens at all. I know the "WidgetTest" activity can run because if I set up an Intent from within the main activity, it launches fine. In case it matters, here is the Android Manifest file: <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.steve" android:versionCode="1" android:versionName="1.0"> <application android:icon="@drawable/icon" android:label="@string/app_name"> <activity android:name=".Volume_Change_Program" android:label="@string/app_name"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> <activity android:name=".WidgetTest" android:label="@string/hello"> <intent_filter> <action android:name="android.intent.action.MAIN"/> <category android:name="android.intent.category.LAUNCHER"/> </intent_filter> </activity> <receiver android:name=".VolumeChangerWidget" > <intent-filter> <action android:name="android.appwidget.action.APPWIDGET_UPDATE" /> </intent-filter> <meta-data android:name="android.appwidget.provider" android:resource="@xml/volume_changer_info" /> </receiver> </application> <uses-sdk android:minSdkVersion="3" /> Is there a way to test where the fault is? I.e. is the fault that the button isn't linked properly to the PendingIntent, or that the PendingIntent or Intent isn't finding WidgetTest.class, etc? Thanks very much for your help! Steve

  • How to Access a descendant object's internal method in C#

    - by Giovanni Galbo
    I'm trying to access a method that is marked as internal in the parent class (in its own assembly) in an object that inherits from the same parent. Let me explain what I'm trying to do... I want to create Service classes that return IEnumberable with an underlying List to non-Service classes (e.g. the UI) and optionally return an IEnumerable with an underlying IQueryable to other services. I wrote some sample code to demonstrate what I'm trying to accomplish, shown below. The example is not real life, so please remember that when commenting. All services would inherit from something like this (only relevant code shown): public class ServiceBase<T> { protected readonly ObjectContext _context; protected string _setName = String.Empty; public ServiceBase(ObjectContext context) { _context = context; } public IEnumerable<T> GetAll() { return GetAll(false); } //These are not the correct access modifiers.. I want something //that is accessible to children classes AND between descendant classes internal protected IEnumerable<T> GetAll(bool returnQueryable) { var query = _context.CreateQuery<T>(GetSetName()); if(returnQueryable) { return query; } else { return query.ToList(); } } private string GetSetName() { //Some code... return _setName; } } Inherited services would look like this: public class EmployeeService : ServiceBase<Employees> { public EmployeeService(ObjectContext context) : base(context) { } } public class DepartmentService : ServiceBase<Departments> { private readonly EmployeeService _employeeService; public DepartmentService(ObjectContext context, EmployeeService employeeService) : base(context) { _employeeService = employeeService; } public IList<Departments> DoSomethingWithEmployees(string lastName) { //won't work because method with this signature is not visible to this class var emps = _employeeService.GetAll(true); //more code... } } Because the parent class lives is reusable, it would live in a different assembly than the child services. With GetAll(bool returnQueryable) being marked internal, the children would not be able to see each other's GetAll(bool) method, just the public GetAll() method. I know that I can add a new internal GetAll method to each service (or perhaps an intermediary parent class within the same assembly) so that each child service within the assembly can see each other's method; but it seems unnecessary since the functionality is already available in the parent class. For example: internal IEnumerable<Employees> GetAll(bool returnIQueryable) { return base.GetAll(returnIQueryable); } Essentially what I want is for services to be able to access other service methods as IQueryable so that they can further refine the uncommitted results, while everyone else gets plain old lists. Any ideas? EDIT You know what, I had some fun playing a little code golf with this... but ultimately I wouldn't be able to use this scheme anyway because I pass interfaces around, not classes. So in my example GetAll(bool returnIQueryable) would not be in the interface, meaning I'd have to do casting, which goes against what I'm trying to accomplish. I'm not sure if I had a brain fart or if I was just too excited trying to get something that I thought was neat to work. Either way, thanks for the responses.

  • OAuth Consumer request for token from ServiceProvider returns InternalServerError

  • Maven/Spring/Java: ClassNotFoundException - but I know class is there...

    - by wuntee
    I have 2 maven projects set up like this: -com.wuntee.rsaAuthenticationManager (jar) -com.wuntee.taac (pom) --taac-backend-gui (jar) --taac-web (war) And 'com.wuntee.rsaAuthenticationManager' is a dep in 'taac-backend-gui'. When running a test case in taac-backend-gui, everything executes fine, but when trying to start the taac-web, I get the following ClassNotFoundException - the library that contains the class 'weblogic.security.SSL.TrustManager' is also in my local maven repository, and set as a dependency of com.wuntee.rsaAuthenticationManager. Does anyone know why I would be getting this error? I have also attempted to directly add the library containing TrustManager to the taac-web project, and still get the same Exception. Any ideas?

  • Data won't save to SQL database, getting error "close() was never explicitly called on database"

    - by SnowLeppard
    I have a save button in the activity where the user enters data which does this: String subjectName = etName.getText().toString(); String subjectColour = etColour.getText().toString(); SQLDatabase entrySubject = new SQLDatabase(AddSubject.this); entrySubject.open(); entrySubject.createSubjectEntry(subjectName, subjectColour); entrySubject.close(); Which refers to this SQL database class: package com.***.schooltimetable; import android.content.ContentValues; import android.content.Context; import android.database.Cursor; import android.database.SQLException; import android.database.sqlite.SQLiteDatabase; import android.database.sqlite.SQLiteOpenHelper; public class SQLDatabase { public static final String KEY_SUBJECTS_ROWID = "_id"; public static final String KEY_SUBJECTNAME = "name"; public static final String KEY_COLOUR = "colour"; private static final String DATABASE_NAME = "Database"; private static final String DATABASE_TABLE_SUBJECTS = "tSubjects"; private static final int DATABASE_VERSION = 1; private DbHelper ourHelper; private final Context ourContext; private SQLiteDatabase ourDatabase; private static class DbHelper extends SQLiteOpenHelper { public DbHelper(Context context) { super(context, DATABASE_NAME, null, DATABASE_VERSION); // TODO Auto-generated constructor stub } @Override public void onCreate(SQLiteDatabase db) { // TODO Auto-generated method stub db.execSQL("CREATE TABLE " + DATABASE_TABLE_SUBJECTS + " (" + KEY_SUBJECTS_ROWID + " INTEGER PRIMARY KEY AUTOINCREMENT, " + KEY_SUBJECTNAME + " TEXT NOT NULL, " + KEY_COLOUR + " TEXT NOT NULL);"); } @Override public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) { // TODO Auto-generated method stub db.execSQL("DROP TABLE IF EXISTS " + DATABASE_TABLE_SUBJECTS); onCreate(db); } } public SQLDatabase(Context c) { ourContext = c; } public SQLDatabase open() throws SQLException { ourHelper = new DbHelper(ourContext); ourDatabase = ourHelper.getWritableDatabase(); return this; } public void close() { ourHelper.close(); } public long createSubjectEntry(String subjectName, String subjectColour) { // TODO Auto-generated method stub ContentValues cv = new ContentValues(); cv.put(KEY_SUBJECTNAME, subjectName); cv.put(KEY_COLOUR, subjectColour); return ourDatabase.insert(DATABASE_TABLE_SUBJECTS, null, cv); } public String[][] getSubjects() { // TODO Auto-generated method stub String[] Columns = new String[] { KEY_SUBJECTNAME, KEY_COLOUR }; Cursor c = ourDatabase.query(DATABASE_TABLE_SUBJECTS, Columns, null, null, null, null, null); String[][] Result = new String[1][]; // int iRow = c.getColumnIndex(KEY_LESSONS_ROWID); int iName = c.getColumnIndex(KEY_SUBJECTNAME); int iColour = c.getColumnIndex(KEY_COLOUR); for (c.moveToFirst(); !c.isAfterLast(); c.moveToNext()) { Result[0][c.getPosition()] = c.getString(iName); Result[1][c.getPosition()] = c.getString(iColour); Settings.subjectCount = c.getPosition(); TimetableEntry.subjectCount = c.getPosition(); } return Result; } This class has other variables and other variations of the same methods for multiple tables in the database, i've cut out the irrelevant ones. I'm not sure what I need to close and where, I've got the entrySubject.close() in my activity. I used the methods for the database from the NewBoston tutorials. Can anyone see what I've done wrong, or where my problem is? Thanks.

It says 07-08 02:10:03.755: W/ActivityManager(60): Unable to start service Intent { act=com.google.android.c2dm.intent.REGISTER (has extras) }: not found in the logcat.

  • Trouble with datasource not being called from viewWillAppear

    - by user278859
    A little background. I have taken GCCalendar which only works in portrait orientation and extended it to work in landscape similar to how the iPhone's Calendar app works. I did this by duplicating the main view class and modifying it to work in landscape. So when the phone is in portrait orientation the CGCalendar is instantiated from the apps main view controller using the original portrait view class and when in landscape orientation using the new modified landscape view class. Most of the other classes in GCCalendar are shared without modification. A few had to be duplicated as well. I got it all working great except for an issue with the datasource. The datasource is called when the calendar is first loaded and each time the user changes the dates being viewed. Problem is I can't get the datasource call to work on the first call. I am stumped as it works fine in portrait orientation and I cannot find any difference between the 2 versions. Following is some of the code that shows how it gets to the datasource call the first time. Subsequent calls removes all the calendar subviews and instantiates them again with the new dates. The duplicated landscape class names end in LS. Otherwise as you can see they are identical. Does anyone has any idea of where else I might look to resolve this issue? Thanks, John -------------------------------- //App main view controller - (void)showLandscapeCalendar { GCCalendarLandscapeView *calendar = [[[GCCalendarLandscapeView alloc] init] autorelease]; calendar.dataSource = self; calendar.delegate = self; navigationController = [[UINavigationController alloc] initWithRootViewController:calendar]; [self presentModalViewController:navigationController animated:YES]; } - (void)showPortraitCalendar { GCCalendarPortraitView *calendar = [[[GCCalendarPortraitView alloc] init] autorelease]; calendar.dataSource = self; calendar.delegate = self; navigationController = [[UINavigationController alloc] initWithRootViewController:calendar]; [self presentModalViewController:navigationController animated:YES]; } - (NSArray *)calendarEventsForDate:(NSDate *)date{ //build and return the events array //this is the protocol datasource method //It is supposed to run every time the date changes in the calendar } ------------------------------- // GCCalendarLandscapeView... - (void)viewWillAppear:(BOOL)animated { [super viewWillAppear:animated]; if (viewDirty) { [self reloadDayAnimated:NO context:NULL]; viewDirty = NO; } viewVisible = YES; } - (void)reloadDayAnimated:(BOOL)animated context:(void *)context { GCCalendarDayViewLS *nextDayView = [[GCCalendarDayViewLS alloc] initWithCalendarView:self]; } ------------------------------- //GCCalendarDayViewLS - (id)initWithCalendarView:(GCCalendarView *)view { if (self = [super init]) { dataSource = view.dataSource; } return self; } - (void)reloadData { //** first time through the dataSource method does not run events = [dataSource calendarEventsForDate:date]; } ------------------------------- // GCCalendarPortraitView... - (void)viewWillAppear:(BOOL)animated { [super viewWillAppear:animated]; if (viewDirty) { [self reloadDayAnimated:NO context:NULL]; viewDirty = NO; } viewVisible = YES; } - (void)reloadDayAnimated:(BOOL)animated context:(void *)context { GCCalendarDayView *nextDayView = [[GCCalendarDayView alloc] initWithCalendarView:self]; } ------------------------------- //GCCalendarDayView - (id)initWithCalendarView:(GCCalendarView *)view { if (self = [super init]) { dataSource = view.dataSource; } return self; } - (void)reloadData { **//this one works every time events = [dataSource calendarEventsForDate:date]; }

  • CABasicAnimation not scrolling with rest of View

    - by morgman
    All, I'm working on reproducing the pulsing Blue circle effect that the map uses to show your own location... I layered a UIView over a MKMapView. The UIView contains the pulsing animation. I ended up using the following code gleaned from numerous answers here on stackoverflow: CABasicAnimation* pulseAnimation = [CABasicAnimation animationWithKeyPath:@"opacity"]; pulseAnimation.toValue = [NSNumber numberWithFloat: 0.0]; pulseAnimation.duration = 1.0; pulseAnimation.repeatCount = HUGE_VALF; pulseAnimation.autoreverses = YES; pulseAnimation.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]; [self.layer addAnimation:pulseAnimation forKey:@"pulseAnimation"]; CABasicAnimation* resizeAnimation = [CABasicAnimation animationWithKeyPath:@"bounds.size"]; resizeAnimation.toValue = [NSValue valueWithCGSize:CGSizeMake(0.0f, 0.0f)]; resizeAnimation.fillMode = kCAFillModeBoth; resizeAnimation.duration = 1.0; resizeAnimation.repeatCount = HUGE_VALF; resizeAnimation.autoreverses = YES; resizeAnimation.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]; [self.layer addAnimation:resizeAnimation forKey:@"resizeAnimation"]; This does an acceptable job of pulsing/fading a circle I drew in the UIView using: CGContextRef context = UIGraphicsGetCurrentContext(); CGContextSetRGBStrokeColor(context, 1.0, 0.0, 0.0, 0.4); // And draw with a blue fill color CGContextSetRGBFillColor(context, 1.0, 0.0, 0.0, 0.1); // Draw them with a 2.0 stroke width so they are a bit more visible. CGContextSetLineWidth(context, 2.0); CGContextAddEllipseInRect(context, CGRectMake(x-30, y-30, 60.0, 60.0)); CGContextDrawPath(context, kCGPathFillStroke); But I soon found that while this appears to work, as soon as I drag the underlying map to another position the animation screws up... While the position I want highlighted is centered on the screen the animation works ok, once I've dragged the position so it's no longer centered the animation now pulses starting at the center of the screen scaling up to center on the position dragged off center, and back again... A humorous and cool effect, but not what I was looking for. I realize I may have been lucky on several fronts. I'm not sure what I misunderstood. I think the animation is scaling the entire layer which just happens to have my circle drawn in the middle of it. So it works when centered but not when off center. I tried the following gleaned from one of the questions suggested by stackoverflow when I started this question: CABasicAnimation* translateAnimation = [CABasicAnimation animationWithKeyPath:@"position"]; translateAnimation.fromValue = [NSValue valueWithCGPoint:CGPointMake(oldx, oldy )]; translateAnimation.toValue = [NSValue valueWithCGPoint:CGPointMake(x, y )]; // translateAnimation.fillMode = kCAFillModeBoth; translateAnimation.duration = 1.0; translateAnimation.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]; [self.layer addAnimation:translateAnimation forKey:@"translateAnimation"]; But it doesn't help much, when I play with it sometimes it looks like once time it animates in the correct spot after I've moved it offcenter, but then it switches back to the animating from the center point to the new location. Sooo, any suggestions or do I need to provide additional information.

  • Entity Framework RC1 DbContext query issue

    - by Steve
    I'm trying to implement the repository pattern using entity framework code first rc 1. The problem I am running into is with creating the DbContext. I have an ioc container resolving the IRepository and it has a contextprovider which just news up a new DbContext with a connection string in a windsor.config file. With linq2sql this part was no problem but EF seems to be choking. I'll describe the problem below with an example. I've pulled out the code to simplify things a bit so that is why you don't see any repository pattern stuff here. just sorta what is happening without all the extra code and classes. using (var context = new PlssContext()) { var x = context.Set<User>(); var y = x.Where(u => u.UserName == LogOnModel.UserName).FirstOrDefault(); } using (var context2 = new DbContext(@"Data Source=.\SQLEXPRESS;Initial Catalog=PLSS.Models.PlssContext;Integrated Security=True;MultipleActiveResultSets=True")) { var x = context2.Set<User>(); var y = x.Where(u => u.UserName == LogOnModel.UserName).FirstOrDefault(); } PlssContext is where I am creating my DbContext class. The repository pattern doesn't know anything about PlssContext. The best I thought I could do was create a DbContext with the connection string to the sqlexpress database and query the data that way. The connection string in the var context2 was grabbed from the context after newing up the PlssContext object. So they are pointing at the same sqlexpress database. The first query works. The second query fails miserably with this error: The model backing the 'DbContext' context has changed since the database was created. Either manually delete/update the database, or call Database.SetInitializer with an IDatabaseInitializer instance. For example, the DropCreateDatabaseIfModelChanges strategy will automatically delete and recreate the database, and optionally seed it with new data. on this line var y = x.Where(u => u.UserName == LogOnModel.UserName).FirstOrDefault(); Here is my DbContext namespace PLSS.Models { public class PlssContext : DbContext { public DbSet<User> Users { get; set; } public DbSet<Corner> Corners { get; set; } public DbSet<Lookup_County> Lookup_County { get; set; } public DbSet<Lookup_Accuracy> Lookup_Accuracy { get; set; } public DbSet<Lookup_MonumentStatus> Lookup_MonumentStatus { get; set; } public DbSet<Lookup_CoordinateSystem> Lookup_CoordinateSystem { get; set; } public class Initializer : DropCreateDatabaseAlways<PlssContext> { protected override void Seed(PlssContext context) { I've tried all of the Initializer strategies with the same errors. I don't think the database is changing. If I remove the modelBuilder.Conventions.Remove<IncludeMetadataConvention>(); Then the error returns is The entity type User is not part of the model for the current context. Which sort of makes sense. But how do you bring this all together?

    I created a Spring-MVC project. web.xml: <servlet> <servlet-name>mvc-dispatcher</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>mvc-dispatcher</servlet-name> <url-pattern>/soundmails</url-pattern> </servlet-mapping> mvc-dispatcher-servlet.xml <?xml version="1.0"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd"> <mvc:annotation-driven /> <context:component-scan base-package="somepkg.controllers" /> <bean id="multipartResolver" class="org.gmr.web.multipart.GMultipartResolver"> <property name="maxUploadSize" value="1048576" /> </bean> <bean id="placeholderConfig" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> <!-- property name="location"> <value>/WEB-INF/social.properties</value> </property--> </bean> <bean id="jacksonMessageConverter" class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter"></bean> <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"> <property name="messageConverters"> <list> <ref bean="jacksonMessageConverter"/> </list> </property> </bean> </beans> The controller has this code: ProjectController.java @Controller @RequestMapping("/soundmails") public class FileUploadController { @RequestMapping(value="/test", method=RequestMethod.GET) public @ResponseBody String test() { System.out.println("Hai"); return "Hai"; } } I am using Google App Engine in my local machine to test this.

That is also giving the same error. I am using Spring 3.1.0.RELEASE Can someone help me figure out what I am missing - /soundmails/test is giving 404 error. Edit I am unable to enable DEBUG logs for this. For some reason, it is not taking log level configured in logging.properties But I observed something interesting: 1) If I map the request to empty string (value = "") @RequestMapping(value="", method=RequestMethod.GET) public @ResponseBody String test() { System.out.println("Hai"); return "Hai"; } Then, when I try to access 127.0.0.1/soundmails, it works fine (returns string "Hai"). 2) When I have value="/test" @RequestMapping(value="/test", method=RequestMethod.GET) public @ResponseBody String test() { System.out.println("Hai"); return "Hai"; } and I try to access 127.0.0.1/soundmails/test, it is giving HTTP 404. This is weird.

  • Java, LDAP: Make it not ignore blank passwords?

    - by Steve
    I'm maintaining some legacy Java LDAP code. I know next to nothing about LDAP. The program below basically just sends the userid and password to the LDAP server, receives notification back if the credentials are good. If so, it prints out the LDAP attributes received from the LDAP server, if not it prints out an exception. All works well if a bad password is given. An "invalid credentials" exception gets thrown. However, if a blank password is sent to the LDAP Server, authentication will still happen, LDAP attributes will still be returned. Is this unhappy situation due to the LDAP server allowing blank passwords, or does the code below need to be adjusted such a blank password will get fed to the LDAP server in such a way so it will get rejected? I do have data validation in place. I took it off in a testing environment to solve another issue and noticed this problem. I would prefer not to have this problem underneath the data validation. Thanks much in advance for any information import javax.naming.*; import javax.naming.directory.*; import java.util.*; import java.sql.*; public class LDAPTEST { public static void main(String args[]) { String lcf = "com.sun.jndi.ldap.LdapCtxFactory"; String ldapurl = "ldaps://ldap-cit.smew.acme.com:636/o=acme.com"; String loginid = "George.Jetson"; String password = ""; DirContext ctx = null; Hashtable env = new Hashtable(); Attributes attr = null; Attributes resultsAttrs = null; SearchResult result = null; NamingEnumeration results = null; int iResults = 0; int iAttributes = 0; env.put(Context.INITIAL_CONTEXT_FACTORY, lcf); env.put(Context.PROVIDER_URL, ldapurl); env.put(Context.SECURITY_PROTOCOL, "ssl"); env.put(Context.SECURITY_AUTHENTICATION, "simple"); env.put(Context.SECURITY_PRINCIPAL, "uid=" + loginid + ",ou=People,o=acme.com"); env.put(Context.SECURITY_CREDENTIALS, password); try { ctx = new InitialDirContext(env); attr = new BasicAttributes(true); attr.put(new BasicAttribute("uid",loginid)); results = ctx.search("ou=People",attr); while (results.hasMore()) { result = (SearchResult)results.next(); resultsAttrs = result.getAttributes(); for (NamingEnumeration enumAttributes = resultsAttrs.getAll(); enumAttributes.hasMore();) { Attribute a = (Attribute)enumAttributes.next(); System.out.println("attribute: " + a.getID() + " : " + a.get().toString()); iAttributes++; }// end for loop iResults++; }// end while loop System.out.println("Records == " + iResults + " Attributes: " + iAttributes); }// end try catch (Exception e) { e.printStackTrace(); } }// end function main() }// end class LDAPTEST

  • Minimize Windows Live Mail to the System Tray in Windows 7

    - by Asian Angel
    Are you frustrated that you can not minimize Windows Live Mail to the system tray in Windows 7? With just a few tweaks you can make Live Mail minimize to the system tray just like in earlier versions of Windows. Windows Live Mail in Windows Vista In Windows Vista you could minimize Windows Live Mail to the system tray if desired using the context menu… Windows Live Mail in Windows 7 In Windows 7 you can minimize the app window but not hide it in the system tray. The Hide window when minimized menu entry is missing from the context menu and all you have is the window icon taking up space in your taskbar. How to Add the Context Menu Entry Back Right click on the program shortcut(s) and select properties. When the properties window opens click on the compatibility tab and enable the Run this program in compatibility mode for setting. Choose Windows Vista (Service Pack 2) from the drop-down menu and click OK. Once you have restarted Windows Live Mail you will have access to the Hide window when minimized menu entry again. And just like that your taskbar is clear again when Windows Live Mail is minimized. If you have wanted the ability to minimize Windows Live Mail to the system tray in Windows 7 then this little tweak will fix the problem.

In ASP.NET 4, by default, request validation is enabled for all requests, because it is enabled before the BeginRequest phase of an HTTP request. As a result, request validation applies to requests for all ASP.NET resources, not just .aspx page requests. This includes requests such as Web service calls and custom HTTP handlers. Request validation is also active when custom HTTP modules are reading the contents of an HTTP request. Solution: To revert to the behavior of the ASP.NET 2.0 request validation feature, add the following setting in the Web.config file: <system.web>  <httpRuntime requestValidationMode=”2.0? /> </system.web>

  • Entity Framework version 1- Brief Synopsis and Tips &ndash; Part 1

    - by Rohit Gupta
    To Do Eager loading use Projections (for e.g. from c in context.Contacts select c, c.Addresses)  or use Include Query Builder Methods (Include(“Addresses”)) If there is multi-level hierarchical Data then to eager load all the relationships use Include Query Builder methods like customers.Include("Order.OrderDetail") to include Order and OrderDetail collections or use customers.Include("Order.OrderDetail.Location") to include all Order, OrderDetail and location collections with a single include statement =========================================================================== If the query uses Joins then Include() Query Builder method will be ignored, use Nested Queries instead If the query does projections then Include() Query Builder method will be ignored Use Address.ContactReference.Load() OR Contact.Addresses.Load() if you need to Deferred Load Specific Entity – This will result in extra round trips to the database ObjectQuery<> cannot return anonymous types... it will return a ObjectQuery<DBDataRecord> Only Include method can be added to Linq Query Methods Any Linq Query method can be added to Query Builder methods. If you need to append a Query Builder Method (other than Include) after a LINQ method  then cast the IQueryable<Contact> to ObjectQuery<Contact> and then append the Query Builder method to it =========================================================================== Query Builder methods are Select, Where, Include Methods which use Entity SQL as parameters e.g. "it.StartDate, it.EndDate" When Query Builder methods do projection then they return ObjectQuery<DBDataRecord>, thus to iterate over this collection use contact.Item[“Name”].ToString() When Linq To Entities methods do projection, they return collection of anonymous types --- thus the collection is strongly typed and supports Intellisense EF Object Context can track changes only on Entities, not on Anonymous types. If you use a Defining Query for a EntitySet then the EntitySet becomes readonly since a Defining Query is the same as a View (which is treated as a ReadOnly by default). However if you want to use this EntitySet for insert/update/deletes then we need to map stored procs (as created in the DB) to the insert/update/delete functions of the Entity in the Designer You can use either Execute method or ToList() method to bind data to datasources/bindingsources If you use the Execute Method then remember that you can traverse through the ObjectResult<> collection (returned by Execute) only ONCE. In WPF use ObservableCollection to bind to data sources , for keeping track of changes and letting EF send updates to the DB automatically. Use Extension Methods to add logic to Entities. For e.g. create extension methods for the EntityObject class. Create a method in ObjectContext Partial class and pass the entity as a parameter, then call this method as desired from within each entity. ================================================================ DefiningQueries and Stored Procedures: For Custom Entities, one can use DefiningQuery or Stored Procedures. Thus the Custom Entity Collection will be populated using the DefiningQuery (of the EntitySet) or the Sproc. If you use Sproc to populate the EntityCollection then the query execution is immediate and this execution happens on the Server side and any filters applied will be applied in the Client App. If we use a DefiningQuery then these queries are composable, meaning the filters (if applied to the entityset) will all be sent together as a single query to the DB, returning only filtered results. If the sproc returns results that cannot be mapped to existing entity, then we first create the Entity/EntitySet in the CSDL using Designer, then create a dummy Entity/EntitySet using XML in the SSDL. When creating a EntitySet in the SSDL for this dummy entity, use a TSQL that does not return any results, but does return the relevant columns e.g. select ContactID, FirstName, LastName from dbo.Contact where 1=2 Also insure that the Entity created in the SSDL uses the SQL DataTypes and not .NET DataTypes. If you are unable to open the EDMX file in the designer then note the Errors ... they will give precise info on what is wrong. The Thrid option is to simply create a Native Query in the SSDL using <Function Name="PaymentsforContact" IsComposable="false">   <CommandText>SELECT ActivityId, Activity AS ActivityName, ImagePath, Category FROM dbo.Activities </CommandText></FuncTion> Then map this Function to a existing Entity. This is a quick way to get a custom Entity which is regular Entity with renamed columns or additional columns (which are computed columns). The disadvantage to using this is that It will return all the rows from the Defining query and any filter (if defined) will be applied only at the Client side (after getting all the rows from DB). If you you DefiningQuery instead then we can use that as a Composable Query. The Fourth option (for mapping a READ stored proc results to a non-existent Entity) is to create a View in the Database which returns all the fields that the sproc also returns, then update the Model so that the model contains this View as a Entity. Then map the Read Sproc to this View Entity. The other option would be to simply create the View and remove the sproc altogether. ================================================================ To Execute a SProc that does not return a entity, use a EntityCommand to execute that proc. You cannot call a sproc FunctionImport that does not return Entities From Code, the only way is to use SSDL function calls using EntityCommand.  This changes with EntityFramework Version 4 where you can return Scalar Types, Complex Types, Entities or NonQuery ================================================================ UDF when created as a Function in SSDL, we need to set the Name & IsComposable properties for the Function element. IsComposable is always false for Sprocs, for UDF's set this to true. You cannot call UDF "Function" from within code since you cannot import a UDF Function into the CSDL Model (with Version 1 of EF). only stored procedures can be imported and then mapped to a entity ================================================================ Entity Framework requires properties that are involved in association mappings to be mapped in all of the function mappings for the entity (Insert, Update and Delete). Because Payment has an association to Reservation... hence we need to pass both the paymentId and reservationId to the Delete sproc even though just the paymentId is the PK on the Payment Table. ================================================================ When mapping insert, update and delete procs to a Entity, insure that all the three or none are mapped. Further if you have a base class and derived class in the CSDL, then you must map (ins, upd, del) sprocs to all parent and child entities in the inheritance relationship. Note that this limitation that base and derived entity methods must all must be mapped does not apply when you are mapping Read Stored Procedures.... ================================================================ You can write stored procedures SQL directly into the SSDL by creating a Function element in the SSDL and then once created, you can map this Function to a CSDL Entity directly in the designer during Function Import ================================================================ You can do Entity Splitting such that One Entity maps to multiple tables in the DB. For e.g. the Customer Entity currently derives from Contact Entity...in addition it also references the ContactPersonalInfo Entity. One can copy all properties from the ContactPersonalInfo Entity into the Customer Entity and then Delete the CustomerPersonalInfo entity, finall one needs to map the copied properties to the ContactPersonalInfo Table in Table Mapping (by adding another table (ContactPersonalInfo) to the Table Mapping... this is called Entity Splitting. Thus now when you insert a Customer record, it will automatically create SQL to insert records into the Contact, Customers and ContactPersonalInfo tables even though you have a Single Entity called Customer in the CSDL =================================================================== There is Table by Type Inheritance where another EDM Entity can derive from another EDM entity and absorb the inherted entities properties, for example in the Break Away Geek Adventures EDM, the Customer entity derives (inherits) from the Contact Entity and absorbs all the properties of Contact entity. Thus when you create a Customer Entity in Code and then call context.SaveChanges the Object Context will first create the TSQL to insert into the Contact Table followed by a TSQL to insert into the Customer table =================================================================== Then there is the Table per Hierarchy Inheritance..... where different types are created based on a condition (similar applying a condition to filter a Entity to contain filtered records)... the diference being that the filter condition populates a new Entity Type (derived from the base Entity). In the BreakAway sample the example is Lodging Entity which is a Abstract Entity and Then Resort and NonResort Entities which derive from Lodging Entity and records are filtered based on the value of the Resort Boolean field =================================================================== Then there is Table per Concrete Type Hierarchy where we create a concrete Entity for each table in the database. In the BreakAway sample there is a entity for the Reservation table and another Entity for the OldReservation table even though both the table contain the same number of fields. The OldReservation Entity can then inherit from the Reservation Entity and configure the OldReservation Entity to remove all Scalar Properties from the Entity (since it inherits the properties from Reservation and filters based on ReservationDate field) =================================================================== Complex Types (Complex Properties) Entities in EF can also contain Complex Properties (in addition to Scalar Properties) and these Complex Properties reference a ComplexType (not a EntityType) DropdownList, ListBox, RadioButtonList, CheckboxList, Bulletedlist are examples of List server controls (not data bound controls) these controls cannot use Complex properties during databinding, they need Scalar Properties. So if a Entity contains Complex properties and you need to bind those to list server controls then use projections to return Scalar properties and bind them to the control (the disadvantage is that projected collections are not tracked by the Object Context and hence cannot persist changes to the projected collections bound to controls) ObjectDataSource and EntityDataSource do account for Complex properties and one can bind entities with Complex Properties to Data Source controls and they will be tracked for changes... with no additional plumbing needed to persist changes to these collections bound to controls So DataBound controls like GridView, FormView need to use EntityDataSource or ObjectDataSource as a datasource for entities that contain Complex properties so that changes to the datasource done using the GridView can be persisted to the DB (enabling the controls for updates)....if you cannot use the EntityDataSource you need to flatten the ComplexType Properties using projections With EF Version 4 ComplexTypes are supported by the Designer and can add/remove/compose Complex Types directly using the Designer =================================================================== Conditional Mapping ... is like Table per Hierarchy Inheritance where Entities inherit from a base class and then used conditions to populate the EntitySet (called conditional Mapping). Conditional Mapping has limitations since you can only use =, is null and IS NOT NULL Conditions to do conditional mapping. If you need more operators for filtering/mapping conditionally then use QueryView(or possibly Defining Query) to create a readonly entity. QueryView are readonly by default... the EntitySet created by the QueryView is enabled for change tracking by the ObjectContext, however the ObjectContext cannot create insert/update/delete TSQL statements for these Entities when SaveChanges is called since it is QueryView. One way to get around this limitation is to map stored procedures for the insert/update/delete operations in the Designer. =================================================================== Difference between QueryView and Defining Query : QueryView is defined in the (MSL) Mapping File/section of the EDM XML, whereas the DefiningQuery is defined in the store schema (SSDL). QueryView is written using Entity SQL and is this database agnostic and can be used against any database/Data Layer. DefiningQuery is written using Database Lanaguage i.e. TSQL or PSQL thus you have more control =================================================================== Performance: Lazy loading is deferred loading done automatically. lazy loading is supported with EF version4 and is on by default. If you need to turn it off then use context.ContextOptions.lazyLoadingEnabled = false To improve Performance consider PreCompiling the ObjectQuery using the CompiledQuery.Compile method
