• Cannot connect to a SQL Server 2005 Analysis Services cube after installing SQL Server 2008 SP1.

  - by Luc

  I've been developing an application that talks directly to an SSAS 2005 OLAP cube. Note that I also have SQL Server 2008 installed, so the other day I did a Windows Update and decided to include SQL Server 2008 SP1 in my update. After doing that, my SSAS 2005 cube is no longer accessible from my application. I'm able to browse the data just fine within SQL Server 2005 BI Studio Manager, but I'm not able to connect to the cube from my application. Here is my connection string that used to work: Data Source=localhost;Provider=msolap;Initial Catalog=Adventure Works DW Here is the error message I get: Either the user, [Server]/[User], does not have access to the Adventure Works DW database, or the database does not exist. Here is the beginning of my stack trace if it would help: Microsoft.AnalysisServices.AdomdClient.AdomdErrorResponseException was unhandled by user code HelpLink="" Message="Either the user, Luc-PC\\Luc, does not have access to the Adventure Works DW database, or the database does not exist."

I've looked for a solution for the last 4+ hours and haven't had any success. Thanks in advance for any help. Luc

• Adding visible "Markers" to represent Geopoints to a MapView using ItemizedOverlay in Android

  - by LordSnoutimus

  Hello, I am building an application which stores GPS locations in a SQLite database and then outputs the data onto a MapView using an Overlay by drawing a red line between the points. I want to be able to show graphical markers (images) for each of these points as well as the red line. My code is as follows: public class MyOverlay extends ItemizedOverlay { // private Projection projection; private Paint linePaint; private Vector points; public MyOverlay(Drawable defaultMarker) { super(defaultMarker); points = new Vector<GeoPoint>(); //set colour, stroke width etc. linePaint = new Paint(); linePaint.setARGB(255, 255, 0, 0); linePaint.setStrokeWidth(3); linePaint.setDither(true); linePaint.setStyle(Style.FILL); linePaint.setAntiAlias(true); linePaint.setStrokeJoin(Paint.Join.ROUND); linePaint.setStrokeCap(Paint.Cap.ROUND); } public void addPoint(GeoPoint point) { populate(); points.addElement(point); } //public void setProjection(Projection projection) { // this.projection = projection; // } public void draw(Canvas canvas, MapView view, boolean shadow) { populate(); int size = points.size(); Point lastPoint = new Point(); if(size == 0) return; view.getProjection().toPixels(points.get(0), lastPoint); Point point = new Point(); for(int i = 1; i<size; i++){ view.getProjection().toPixels(points.get(i), point); canvas.drawLine(lastPoint.x, lastPoint.y, point.x, point.y, linePaint); lastPoint = point; } } @Override protected OverlayItem createItem(int arg0) { // TODO Auto-generated method stub return null; } @Override public int size() { // TODO Auto-generated method stub return 0; } } What would be the easiest way to implement adding markers for each GeoPoint? Thanks

• Android - drawing path as overlay on MapView

  - by Rabas

  Hello, I have a class that extends Overlay and implemments Overlay.Snappable. I have overriden its draw method: @Override public void draw(Canvas canvas, MapView mv, boolean shadow) { Projection projection = mv.getProjection(); ArrayList<GeoPoint> geoPoints = new ArrayList<GeoPoint>(); //Creating geopoints - ommited for readability Path p = new Path(); for (int i = 0; i < geoPoints.size(); i++) { if (i == geoPoints.size() - 1) { break; } Point from = new Point(); Point to = new Point(); projection.toPixels(geoPoints.get(i), from); projection.toPixels(geoPoints.get(i + 1), to); p.moveTo(from.x, from.y); p.lineTo(to.x, to.y); } Paint mPaint = new Paint(); mPaint.setStyle(Style.FILL); mPaint.setColor(0xFFFF0000); mPaint.setAntiAlias(true); canvas.drawPath(p, mPaint); super.draw(canvas, mv, shadow); } As you can see, I make a list of points on a map and I want them to form a polygonal shape. Now, the problem is that when I set paint style to be FILL or FILL_AND_STROKE nothing shows up on the screen, but when I set it to be just stroke, and set stroke width, it acctually draws what it is supposed to draw. Now, I looked for solution, but nothing comes up. Can you tell me if I something missed to set in the code itself, or are there some sorts of constraints when drawing on Overlay canvases? Thanks

• DotNetOpenAuth RelayParty not working on load balanced cluster

  - by Garth

  We're trying to move an ASP.NET MVC application, which uses DotNetOpenAuth OpenID Version 3.4.1, from a single server web garden to a physical server cluster held behind a hardware load balancer. Our old setup (OpenID RP working): Browser = SHTTP = Server = WebGarden = Nonce/Session Store Our new setup (OpenID RP not working): Browser = SHTTP = Load Balancer = HTTP = Cluster Node = WebGarden = Nonce/Session Store DB When we authenticate with the new setup we are correctly redirected to the OpenID Provider but after authenticated we are redirected back to our cluster (relay party) and get the following exception: Exception DotNetOpenAuth.Messaging.ProtocolException: Redirects on POST requests that are to untrusted servers is not supported. at DotNetOpenAuth.Messaging.ErrorUtilities.VerifyProtocol(Boolean condition, String message, Object[] args) in c:\TeamCity\buildAgent\work\bf9e2ca68b75a334\src\DotNetOpenAuth\Messaging\ErrorUtilities.cs:line 235 at DotNetOpenAuth.Messaging.UntrustedWebRequestHandler.GetResponse(HttpWebRequest request, DirectWebRequestOptions options) in c:\TeamCity\buildAgent\work\bf9e2ca68b75a334\src\DotNetOpenAuth\Messaging\UntrustedWebRequestHandler.cs:line 258 at DotNetOpenAuth.OpenId.ChannelElements.OpenIdChannel.GetDirectResponse(HttpWebRequest webRequest) in c:\TeamCity\buildAgent\work\bf9e2ca68b75a334\src\DotNetOpenAuth\OpenId\ChannelElements\OpenIdChannel.cs:line 277 at DotNetOpenAuth.Messaging.Channel.RequestCore(IDirectedProtocolMessage request) in c:\TeamCity\buildAgent\work\bf9e2ca68b75a334\src\DotNetOpenAuth\Messaging\Channel.cs:line 542 at DotNetOpenAuth.Messaging.Channel.Request(IDirectedProtocolMessage requestMessage) in c:\TeamCity\buildAgent\work\bf9e2ca68b75a334\src\DotNetOpenAuth\Messaging\Channel.cs:line 425 at DotNetOpenAuth.Messaging.Channel.Request[TResponse](IDirectedProtocolMessage requestMessage) in c:\TeamCity\buildAgent\work\bf9e2ca68b75a334\src\DotNetOpenAuth\Messaging\Channel.cs:line 405 at DotNetOpenAuth.OpenId.ChannelElements.SigningBindingElement.ProcessIncomingMessage(IProtocolMessage message) in c:\TeamCity\buildAgent\work\bf9e2ca68b75a334\src\DotNetOpenAuth\OpenId\ChannelElements\SigningBindingElement.cs:line 154 at DotNetOpenAuth.Messaging.Channel.ProcessIncomingMessage(IProtocolMessage message) in c:\TeamCity\buildAgent\work\bf9e2ca68b75a334\src\DotNetOpenAuth\Messaging\Channel.cs:line 992 at DotNetOpenAuth.OpenId.ChannelElements.OpenIdChannel.ProcessIncomingMessage(IProtocolMessage message) in c:\TeamCity\buildAgent\work\bf9e2ca68b75a334\src\DotNetOpenAuth\OpenId\ChannelElements\OpenIdChannel.cs:line 172 at DotNetOpenAuth.Messaging.Channel.ReadFromRequest(HttpRequestInfo httpRequest) in c:\TeamCity\buildAgent\work\bf9e2ca68b75a334\src\DotNetOpenAuth\Messaging\Channel.cs:line 386 at DotNetOpenAuth.OpenId.RelyingParty.OpenIdRelyingParty.GetResponse(HttpRequestInfo httpRequestInfo) in c:\TeamCity\buildAgent\work\bf9e2ca68b75a334\src\DotNetOpenAuth\OpenId\RelyingParty\OpenIdRelyingParty.cs:line 501 We have added a machines involved into the trusted machine list and turned off requires ssl but it makes no difference. We even tried removing out nonce store and using a stateless connection, but that didn't work either. We always get the same error. We suspected the issue is arising as a result of the cluster node having a different IP from the load balancer when it connects to the OpenID Provider, but we're not sure. Any ideas?

• How do you construct an array suitable for numpy sorting?

  - by Alex

  I need to sort two arrays simultaneously, or rather I need to sort one of the arrays and bring the corresponding element of its associated array with it as I sort. That is if the array is [(5, 33), (4, 44), (3, 55)] and I sort by the first axis (labeled below dtype='alpha') then I want: [(3.0, 55.0) (4.0, 44.0) (5.0, 33.0)]. These are really big data sets and I need to sort first ( for nlog(n) speed ) before I do some other operations. I don't know how to merge my two separate arrays though in the proper manner to get the sort algorithm working. I think my problem is rather simple. I tried three different methods: import numpy x=numpy.asarray([5,4,3]) y=numpy.asarray([33,44,55]) dtype=[('alpha',float), ('beta',float)] values=numpy.array([(x),(y)]) values=numpy.rollaxis(values,1) #values = numpy.array(values, dtype=dtype) #a=numpy.array(values,dtype=dtype) #q=numpy.sort(a,order='alpha') print "Try 1:\n", values values=numpy.empty((len(x),2)) for n in range (len(x)): values[n][0]=y[n] values[n][1]=x[n] print "Try 2:\n", values #values = numpy.array(values, dtype=dtype) #a=numpy.array(values,dtype=dtype) #q=numpy.sort(a,order='alpha') ### values = [(x[0], y[0]), (x[1],y[1]) , (x[2],y[2])] print "Try 3:\n", values values = numpy.array(values, dtype=dtype) a=numpy.array(values,dtype=dtype) q=numpy.sort(a,order='alpha') print "Result:\n",q I commented out the first and second trys because they create errors, I knew the third one would work because that was mirroring what I saw when I was RTFM. Given the arrays x and y (which are very large, just examples shown) how do I construct the array (called values) that can be called by numpy.sort properly? *** Zip works great, thanks. Bonus question: How can I later unzip the sorted data into two arrays again?

• Draw Bitmap with alpha channel

  - by Paja

  I have a Format32bppArgb backbuffer, where I draw some lines: var g = Graphics.FromImage(bitmap); g.Clear(Color.FromArgb(0)); var rnd = new Random(); for (int i = 0; i < 5000; i++) { int x1 = rnd.Next(ClientRectangle.Left, ClientRectangle.Right); int y1 = rnd.Next(ClientRectangle.Top, ClientRectangle.Bottom); int x2 = rnd.Next(ClientRectangle.Left, ClientRectangle.Right); int y2 = rnd.Next(ClientRectangle.Top, ClientRectangle.Bottom); Color color = Color.FromArgb(rnd.Next(0, 255), rnd.Next(0, 255), rnd.Next(0, 255)); g.DrawLine(new Pen(color), x1, y1, x2, y2); } Now I want to copy bitmap in Paint event. I do it like this: void Form1Paint(object sender, PaintEventArgs e) { e.Graphics.DrawImageUnscaled(bitmap, 0, 0); } Hovewer, the DrawImageUnscaled copies pixels and applies the alpha channel, thus pixels with alpha == 0 won't have any effect. But I need raw byte copy, so pixels with alpha == 0 are also copied. So the result of these operations should be that e.Graphics contains exact byte-copy of the bitmap. How to do that? Summary: When drawing a bitmap, I don't want to apply the alpha channel, I merely want to copy the pixels.

• VB .NET DirectCast and Type Reflection

  - by msarchet

  The application that I am working on has a generic Parent Form called RSChild, that is used to perform some operations depending on whether or not the control that is contained within it is in a MdiTabManager or inside of its own modal form. Then the actual User Controls contained within Inherit from a Interface Called ObjectEdit (Objects that we allow to be edited). At a point in my code I am doing this. Public Function doesTabExist(ByVal id As Integer, ByVal recordType As Enums.eRecordType) As Boolean Dim alikePages As Object = (From tabs In DirectCast(Control.FromHandle(MainForm.SharedHandle), MainForm).XtraTabbedMdiManager1.Pages Where DirectCast(tabs.MdiChild, RSChild).RSObject.RecordType = recordType Select tabs) For Each page As DevExpress.XtraTabbedMdi.XtraMdiTabPage In alikePages Select Case recordType Case Enums.eRecordType.Doctor If id = DirectCast(castTabPageToRSChild(page).RSObject, UI.Doctor).ID Then pageToActive(page) Return True End If 'rest of the cases so the case block is repeated 10 times' End Function And my castTabPageToRSChild(page) is a lambda function as Such Dim castTabPageToRSChild As Func(Of DevExpress.XtraTabbedMdi.XtraMdiTabPage, RSChild) = Function(page) DirectCast(page.MdiChild, RSChild) So my Question is, I have about 10 case statements, all because I can't seem to find a way to use reflection to get the underlying Type of the RSObject Object. So I have the whole If block repeated over and over. I tried doing castTabPageToRSChild(page)RSObject.GetType and using that in the DirectCast and I also tried creating another object that was separate from that and doing the same thing. My code works as intended I'm just trying to see if there is a manner in which I didn't have a lot of replicated code. My vision would be to do something like For Each page As XtraMdiTabPage In alikePages If id = DirectCast(castTabPageToRSchild(page).RSObject, TypeOfThatObject).Id Then Return True Next However I have a feeling this is not possible due to the behavior of DirectCast.

• Why does Graphviz fail on gvLayout?

  - by David Brown

  Once again, here I am writing C without really knowing what I'm doing... I've slapped together a simple function that I can call from a C# program that takes a DOT string, an output format, and a file name and renders a graph using Graphviz. #include "types.h" #include "graph.h" #include "gvc.h" #define FUNC_EXPORT __declspec(dllexport) // Return codes #define GVUTIL_SUCCESS 0 #define GVUTIL_ERROR_GVC 1 #define GVUTIL_ERROR_DOT 2 #define GVUTIL_ERROR_LAYOUT 3 #define GVUTIL_ERROR_RENDER 4 FUNC_EXPORT int RenderDot(char * dotData, const char * format, const char * fileName) { Agraph_t * g; // The graph GVC_t * gvc; // The Graphviz context int result; // Result of layout and render operations // Create a new graphviz context gvc = gvContext(); if (!gvc) return GVUTIL_ERROR_GVC; // Read the DOT data into the graph g = agmemread(dotData); if (!g) return GVUTIL_ERROR_DOT; // Layout the graph result = gvLayout(gvc, g, "dot"); if (result) return GVUTIL_ERROR_LAYOUT; // Render the graph result = gvRenderFilename(gvc, g, format, fileName); if (result) return GVUTIL_ERROR_RENDER; // Free the layout gvFreeLayout(gvc, g); // Close the graph agclose(g); // Free the graphviz context gvFreeContext(gvc); return GVUTIL_SUCCESS; } It compiles fine, but when I call it, I get GVUTIL_ERROR_LAYOUT. At first, I thought it might have been how I was declaring my P/Invoke signature, so I tested it from a C program instead, but it still failed in the same way. RenderDot("digraph graphname { a -> b -> c; }", "png", "C:\testgraph.png"); Did I miss something? EDIT If there's a chance it has to do with how I'm compiling the code, here's the command I'm using: cl gvutil.c /I "C:\Program Files (x86)\Graphviz2.26\include\graphviz" /LD /link /LIBPATH:"C:\Program Files (x86)\Graphviz2.26\lib\release" gvc.lib graph.lib cdt.lib pathplan.lib I've been following this tutorial that explains how to use Graphviz as a library, so I linked to the .lib files that it listed.

• Delphi: How to respond to WM_SettingChange/WM_WinIniChange?

  - by Ian Boyd

  i need to know when my application recieves a WM_SETTINGCHANGE message (formerly known as WM_WININICHANGE). Problem is that the message pump in TApplication sends it down a black hole (default handler) before i can get a chance to see it: procedure TApplication.WndProc(var Message: TMessage); ... begin Message.Result := 0; for I := 0 to FWindowHooks.Count - 1 do if TWindowHook(FWindowHooks[I]^)(Message) then Exit; CheckIniChange(Message); with Message do case Msg of WM_SETTINGCHANGE: begin Mouse.SettingChanged(wParam); Default; <----------------------*poof* down the sink hole end; ... end; ... end; The procedure CheckIniChange() doesn't throw any event i can handle, neither does Mouse.SettingChanged(). And once the code path reaches Default, it is sent down the DefWindowProc drain hole, never to be seen again (since the first thing the WndProc does is set the Message.Result to zero. i was hoping to assign a handler to a TApplicationEvents.OnMessage event: procedure TdmGlobal.ApplicationEvents1Message(var Msg: tagMSG; var Handled: Boolean); begin case Msg.message of WM_SETTINGCHANGE: begin // Code end; end; end; But the OnMessage event is only thrown for messages that come through the message pump. Since the WM_SETTINGCHANGE message is "handled", it never sees the PeekMessage TranslateMessage DispatchMessage system. How can i respond to the windows broadcast WM_SETTINGCHANGE?

• What is the equivalent of Application.ProcessMessages, Application.Handle and Application.Terminated

  - by DavidB

  Hi, I am new to Writing Windows Service apps and having problems. Written in Delphi, I have written a normal windows application to check and debug the major parts of the code and now have to convert it to an NT Service. My code has to launch a windows application which I do using the following code. function Run_Program : boolean; var SEInfo : TShellExecuteInfo; ExitCode : DWORD; begin Result := false; FillChar(SEInfo, SizeOf(SEInfo),0); SEInfo.cbSize :=SizeOf(TShellExecuteInfo); With SEInfo do begin fMask := SEE_MASK_NOCLOSEPROCESS; Wnd := **Application.Handle**; lpFile := PChar(Exe_Prog); lpParameters := PChar(Exe_Param); nShow := SW_SHOWNORMAL; end; If ShellExecuteEx(@SEInfo) then begin repeat Application.ProcessMessages; GetExitCodeProcess(SEInfo.hProcess, ExitCode); until (ExitCode <> STILL_ACTIVE) OR Application.Terminated OR NOT q1.fieldbyName('Delay').AsBoolean; If ExitCode <> STILL_ACTIVE then Record_Event(Exe_Prog + ' completed ') else Record_Event(Exe_Prog + ' activated '); Result := true; end else Record_Event('Error Starting '+ Exe_Prog+ ' '); end; When this is put in the service app the compiler fails with 3 errors: Undeclared identifiers.. 1) Handle 2) ProcessMessages and 3) Terminated. My question is.. are there equivalent procedures that can be used in a service application or should I approach the problem differently in a service application? Any help would be appreciated

• Overlay only draws line between first 2 GPS points in Android

  - by LordSnoutimus

  Hi, I am experiencing an unusual error using ItemizedOverlay in Android. I am creating a GPS tracking device that plots a route between waypoints stored in a database. When I provide the first two sets of longitude and latitude points through the emulator in Eclipse, it draws a red line just how I want it, but if I send another GPS point, it animates to the point, but does not draw a line from the last point. public class MyOverlay extends ItemizedOverlay { // private Projection projection; private Paint linePaint; private Vector points; public MyOverlay(Drawable defaultMarker) { super(defaultMarker); points = new Vector<GeoPoint>(); //set colour, stroke width etc. linePaint = new Paint(); linePaint.setARGB(255, 255, 0, 0); linePaint.setStrokeWidth(3); linePaint.setDither(true); linePaint.setStyle(Style.FILL); linePaint.setAntiAlias(true); linePaint.setStrokeJoin(Paint.Join.ROUND); linePaint.setStrokeCap(Paint.Cap.ROUND); } public void addPoint(GeoPoint point) { points.addElement(point); } public void draw(Canvas canvas, MapView view, boolean shadow) { int size = points.size(); Point lastPoint = new Point(); if(size == 0) return; view.getProjection().toPixels(points.get(0), lastPoint); Point point = new Point(); for(int i = 1; i<size; i++){ view.getProjection().toPixels(points.get(i), point); canvas.drawLine(lastPoint.x, lastPoint.y, point.x, point.y, linePaint); lastPoint = point; } } @Override protected OverlayItem createItem(int arg0) { // TODO Auto-generated method stub return null; } @Override public int size() { // TODO Auto-generated method stub return 0; } }

• WCF/MSMQ Transport Security with Certificates

  - by user104295

  Hi there, my goal is to secure the communication between MSMQ Queue Managers – I don’t want unknown clients sending messages to my MSMQ server. I have spent many hours now trying to get Transport security working for the net.msmq binding in WCF, where MSMQ is in Workgroup mode and the client and server do not have Active Directory… so I’m using certificates. I have created a new X.509 certificate, called Kristan and put it into the “Trusted people” store on the server and into the My store of Current User of the client. The error I’m getting is: An error occurred while sending to the queue: Unrecognized error -1072824272 (0xc00e0030).Ensure that MSMQ is installed and running. If you are sending to a local queue, ensure the queue exists with the required access mode and authorization. Using smartsniff, I see that there’s no attempted connection with the remote MSMQ, however, it’s an error probably coming from the local queue manager. The stack trace is: at System.ServiceModel.Channels.MsmqOutputChannel.OnSend(Message message, TimeSpan timeout) at System.ServiceModel.Channels.OutputChannel.Send(Message message, TimeSpan timeout) at System.ServiceModel.Dispatcher.OutputChannelBinder.Send(Message message, TimeSpan timeout) at System.ServiceModel.Channels.ServiceChannel.Call(String action, Boolean oneway, ProxyOperationRuntime operation, Object[] ins, Object[] outs, TimeSpan timeout) at System.ServiceModel.Channels.ServiceChannelProxy.InvokeService(IMethodCallMessage methodCall, ProxyOperationRuntime operation) at System.ServiceModel.Channels.ServiceChannelProxy.Invoke(IMessage message) The code:- EndpointAddress endpointAddress = new EndpointAddress(new Uri(endPointAddress)); NetMsmqBinding clientBinding = new NetMsmqBinding(); clientBinding.Security.Mode = NetMsmqSecurityMode.Transport; clientBinding.Security.Transport.MsmqAuthenticationMode = MsmqAuthenticationMode.Certificate; clientBinding.Security.Transport.MsmqProtectionLevel = System.Net.Security.ProtectionLevel.Sign; clientBinding.ExactlyOnce = false; clientBinding.UseActiveDirectory = false; // start new var channelFactory = new ChannelFactory<IAsyncImportApi>(clientBinding, endpointAddress); channelFactory.Credentials.ClientCertificate.SetCertificate("CN=Kristan", StoreLocation.CurrentUser, StoreName.My); The queue is flagged as ‘Authenticated’ on the server. I have checked the effect of this and if I turn off all security in the client send, then I get ‘Signature is invalid’ – which is understandable and shows that it’s definitely looking for a sig. Are there are special ports that I need to check are open for cert-based msmq auth? thanks Kris

• Lucene.NET 2.9 and BitArray/DocIdSet

  - by Paul Knopf

  I found a great example on grabbing facet counts on a base query. It stores the bitarray of the base query to improve the performance each time the a facet gets counted. var genreQuery = new TermQuery(new Term("genre", genre)); var genreQueryFilter = new QueryFilter(genreQuery); BitArray genreBitArray = genreQueryFilter.Bits(searcher.GetIndexReader()); Console.WriteLine("There are " + GetCardinality(genreBitArray) + " document with the genre " + genre); // Next perform a regular search and get its BitArray result Query searchQuery = MultiFieldQueryParser.Parse(term, new[] {"title", "description"}, new[] {BooleanClause.Occur.SHOULD, BooleanClause.Occur.SHOULD}, new StandardAnalyzer()); var searchQueryFilter = new QueryFilter(searchQuery); BitArray searchBitArray = searchQueryFilter.Bits(searcher.GetIndexReader()); Console.WriteLine("There are " + GetCardinality(searchBitArray) + " document containing the term " + term); The only problem is that I am using a newer version of Lucene.NET (2.9) and Filter.Bits is obsolete. We are told to use DocIdSet instead (rather than BitArray). I cannot found out how to do the bitArray.And(bitArray) with a docIdSet. I looked in reflector and found OpenIdSet which has And operations. Not sure if OpenIdSet is the route to go, I'm just stating. Thanks in advance!

• .NET converting simple arrays to List Generics

  - by Manish Sinha

  This question might seem trivial and also stupid at the first glance, but it is much more than this. I have an array of any type T (T[]) and I want to convert it into a List generic (List<T>). Is there any other way apart from creating a Generic list, traversing the whole array and adding the element in the List? Present Situation: string[] strList = {'foo','bar','meh'}; List<string> listOfStr = new List<string>(); foreach(string s in strList) { listOfStr.Add(s); } My ideal situation: string[] strList = {'foo','bar','meh'}; List<string> listOfStr = strList.ToList<string>(); Or: string[] strList = {'foo','bar','meh'}; List<string> listOfStr = new List<string>(strList); I am suggesting the last 2 method names as I think compiler or CLR can perform some optimizations on the whole operations if It want inbuilt. P.S.: I am not talking about the Array or ArrayList Type

• ASP.Net Entity Framework, objectcontext error

  - by Chris Klepeis

  I'm building a 4 layered ASP.Net web application. The layers are: Data Layer Entity Layer Business Layer UI Layer The entity layer has my data model classes and is built from my entity data model (edmx file) in the datalayer using T4 templates (POCO). The entity layer is referenced in all other layers. My data layer has a class called SourceKeyRepository which has a function like so: public IEnumerable<SourceKey> Get(SourceKey sk) { using (dmc = new DataModelContainer()) { var query = from SourceKey in dmc.SourceKeys select SourceKey; if (sk.sourceKey1 != null) { query = from SourceKey in query where SourceKey.sourceKey1 == sk.sourceKey1 select SourceKey; } return query; } } Lazy loading is disabled since I do not want my queries to run in other layers of this application. I'm receiving the following error when attempting to access the information in the UI layer: The ObjectContext instance has been disposed and can no longer be used for operations that require a connection. I'm sure this is because my DataModelContainer "dmc" was disposed. How can I return this IEnumerable object from my data layer so that it does not rely on the ObjectContext, but solely on the DataModel? Is there a way to limit lazy loading to only occur in the data layer?

• Determining the maximum stack depth

  - by Joa Ebert

  Imagine I have a stack-based toy language that comes with the operations Push, Pop, Jump and If. I have a program and its input is the toy language. For instance I get the sequence Push 1 Push 1 Pop Pop In that case the maximum stack would be 2. A more complicated example would use branches. Push 1 Push true If .success Pop Jump .continue .success: Push 1 Push 1 Pop Pop Pop .continue: In this case the maximum stack would be 3. However it is not possible to get the maximum stack by walking top to bottom as shown in this case since it would result in a stack-underflow error actually. CFGs to the rescue you can build a graph and walk every possible path of the basic blocks you have. However since the number of paths can grow quickly for n vertices you get (n-1)! possible paths. My current approach is to simplify the graph as much as possible and to have less possible paths. This works but I would consider it ugly. Is there a better (read: faster) way to attack this problem? I am fine if the algorithm produces a stack depth that is not optimal. If the correct stack size is m then my only constraint is that the result n is n = m. Is there maybe a greedy algorithm available that would produce a good result here?

• Java - Trying to log into website with invalid ssl certificate using httpclient

  - by PCBEEF

  I'm trying to log into site with invalid ssl certificate and I have the following code. I bypass the the invalid cert by using my all certificate and then bypass the invalid Hostname by using hostnameverifier. However, the hostnameverifier does not seem to work and I still get the error message javax.net.ssl.SSLException: hostname in certificate didn't match: The code is: public static void main(String[] args) { TrustManager[] trustAllCerts = new TrustManager[] { new X509TrustManager() { public java.security.cert.X509Certificate[] getAcceptedIssuers() { return null; } public void checkClientTrusted( java.security.cert.X509Certificate[] certs, String authType) { } public void checkServerTrusted( java.security.cert.X509Certificate[] certs, String authType) { } } }; HostnameVerifier hv = new HostnameVerifier() { public boolean verify(String urlHostName, SSLSession session) { System.out.println("Warning: URL Host: "+urlHostName+" vs. "+session.getPeerHost()); return true; } }; try { SSLContext sc = SSLContext.getInstance("SSL"); sc.init(null, trustAllCerts, new java.security.SecureRandom()); HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory()); HttpsURLConnection.setDefaultHostnameVerifier(hv); } catch (Exception e) { } try { DefaultHttpClient httpclient = new DefaultHttpClient(); HttpContext localContext = new BasicHttpContext(); List<NameValuePair> formparams = new ArrayList<NameValuePair>(); formparams.add(new BasicNameValuePair("username", "user")); formparams.add(new BasicNameValuePair("password", "pword")); UrlEncodedFormEntity entity; entity = new UrlEncodedFormEntity(formparams, "UTF-8"); HttpPost httppost = new HttpPost("https://www.mysite.com/"); httppost.setEntity(entity); HttpResponse response = httpclient.execute(httppost, localContext); } catch (UnsupportedEncodingException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } }

• Problem with Mapping Linq-to-Sql on different Types

  - by csharpnoob

  Hi, maybe someone can help. I want to have on mapped Linq-Class different Datatype. This is working: private System.Nullable<short> _deleted = 1; [Column(Storage = "_deleted", Name = "deleted", DbType = "SmallInt", CanBeNull = true)] public System.Nullable<short> deleted { get { return this._deleted; } set { this._deleted = value; } } Sure thing. But no when i want to place some logic for boolean, like this: private System.Nullable<short> _deleted = 1; [Column(Storage = "_deleted", Name = "deleted", DbType = "SmallInt", CanBeNull = true)] public bool deleted { get { if (this._deleted == 1) { return true; } return false; } set { if(value == true) { this._deleted = (short)1; }else { this._deleted = (short)0; } } } I get always runtime error: [TypeLoadException: GenericArguments[2], "System.Nullable`1[System.Int16]", on 'System.Data.Linq.Mapping.PropertyAccessor+Accessor`3[T,V,V2]' violates the constraint of type parameter 'V2'.] I can't change the database to bit.. I need to have casting in mapping class.
