This variation is evident in one of the key misunderstandings about the Oracle Database Cloud Service. People could be forgiven for thinking that the Database Cloud Service was a Database-as-a-Service (DBaaS), but this is actually not true. The Database Cloud Service is a Platform-as-a-Service, which presents a different user and developer interface and has a different set of qualities. A good way to think about the difference between these two varieties of Cloud offerings is that you, the customer, have to deal with things at the level of the offering, but not for anything below it. In practice, this means that you do not have to deal with hardware or system software, including installation and maintenance, for DBaaS. You also do not have much control over configuration of these options. For PaaS, you don’t have to deal with hardware, system software, or database software – and also do not have control over these levels in the stack. So you cannot modify configuration parameters for the database with the Database Cloud Service – your interface is through SQL and PL/SQL, with Application Express, included in the Database Cloud Service, or through JDBC for Java apps running in the Java Cloud Service, or through RESTful Web Services. You will notice what is not mentioned there – SQL*Net. You cannot access your Oracle Database Cloud Service by changing an entry in the TNSNames file and using SQL*Net. So the effort involved in migrating an existing Oracle Database in your data center to the Database Cloud Service may be prohibitive. The good news is that Application Express and the RESTful Web Services wizard in the Database Cloud Service allow you to develop new applications very quickly, and, of course, the provisioning of the entire Database Cloud Service takes only minutes.

• Best triple head display setup

  - by dgel

  I'm currently running Ubuntu 12.04 with a darn good triple head display setup. I've got a VisionTek 900530 Radeon HD 5450 512MB DDR3 PCI Express video card that has two DVI outputs and one Mini DisplayPort that I have connected to a HDMI adapter. I'm running three identical Asus 1920x1080 monitors that each have a DVI, VGA, and HDMI input. I'm using the xorg-edgers ppa, so I'm using the open source radeon driver version 6.99.99. I tried using the ATI binary fglrx driver, but I wasn't able to get the three monitors working properly- the monitor connected via HDMI / DisplayPort wouldn't run at full resolution. The setup is almost perfect: Compiz runs fine and is quite snappy. I'm not able to use that great compiz feature where you can drag a window to the side of a display and it will half maximize. I occasionally experience display corruption weirdness with Unity and need to restart it. When I use a dropdown menu in LibreOffice it often pops the menu down in another window. For example, if I'm using the center monitor and click the Insert menu, the menu pulls down on the monitor to my right, forcing me to chase it. If I chase down the menu and choose Manual Break, the dialog appears over on my left monitor. This absurdity is mildly entertaining but has lost its novelty. I've decided to build a new system and have spared no expense- latest i7 processor, SSD, etc. I really like the performance of the Nvidia binary drivers, so I put two ZOTAC ZT-40707-10L GeForce GT 440 in the system, figuring I'd have four DVI outputs and an awesome triple (or even eventually quad) head setup. Unfortunately it appears that I didn't do sufficient research before my purchase. It seems that Nvidia TwinView only supports two monitors on one card (I guess that's why they call it TwinView...). I messed around with running two X servers, but I really don't want that- being able to drag windows to any monitor is critical. It doesn't sound like Xinerama is an option because from what I understand it simply doesn't support Compiz. I've seen a BaseMosaic option that can be used with the Nvidia drivers that appears to support an almost unlimited number of heads- unfortunately me cheap little cards don't support it. I'm also not sure whether you'll still have all nice maximizing and snapping that TwinView provides, or whether Ubuntu will only see it as one massive display. I put my old trusty ATI card into my new system and installed 12.10. I'm using the opensource radeon drivers again because even in 12.10 I can't get the fglrx binary drivers to do triple head. Unfortunately, even with an unbelievably powerful system the experience is extremely sluggish (much more so than my experience in 12.04). The menu scattering problem appears to be fixed, but I get a lot of nasty Unity display corruption. So finally, my question is this: What hardware / drivers should I use? I'm willing to buy (almost) any video card(s). I have two PCI-Express 3.0 slots on my motherboard (which has an integrated Intel HD card). I'm willing to use ATI or Nvidia cards and willing to run Ubuntu 12.04.1 or 12.10. I'm not a gamer, but do want beautiful and snappy Compiz effects. Does anyone out there have the perfect triple head setup in 12.04 or 12.10? What hardware / drivers are you using? I have those two Nvidia cards but will probably be returning them unless someone knows a way to use them together for a triple head setup. Since I'm having pretty good luck with a single ATI card providing three displays, should I just buy a beefier one with the hopes that it will fix the horrible sluggishness I'm experiencing in 12.10?

• The World of SQL Database Deployment

  - by GGBlogger

  In my early development days, I used Microsoft Access for building databases. It made things easy since I only needed to package the database with the installation package so my clients would have access to it. When we began the development of a new package in Visual Studio .NET I decided to use SQL Server Express. It was free and provided good tools - also free. I thought it was a tremendous idea until it came time to distribute our new software! What a surprise. The nightmare Ah, the choices! Detach the database and have the client reattach it to a newly installed – oh wait. FIRST my new client needs to download and install SQL Server Express with SQL Server Management Studio. That’s not a great thing, but it is one more nightmare step for users who may have other versions of SQL installed. Then the question became – do we detach and reattach or do we do a backup. It was too late (bad planning) to revert to Microsoft Access but we badly needed a simple way to package and distribute both the database AND sample contents. Red Gate to the rescue It took me a while to find an answer but I did find it in a package called SQL Packager sold by a relatively unpublicized company in England called Red Gate. They call their products “ingeniously simple” and I must agree with that description. With SQL Packager you point to the database (more in a minute) you want to distribute. A few mouse clicks and dialogs and you have an executable file that you can ship virtually anywhere and virtually any way which, when run, installs the database on your destination SQL Server instance! It really is that simple. Easier to show than tell Let’s explore a hypothetical case. Let’s say you have a local SQL database of customers and you have decided you want to share it with your subsidiaries or partners. Here is the underlying screen you will see on starting SQL Packager. There are a bunch of possibilities here but I’m going to keep this relatively simple. At this point I simply want to illustrate the simplicity of generating an executable to deliver your database. You will notice that you can set up a new package, edit an existing package or change a bunch of options. Start SQL packager And the following is the default dialog you get on startup. In the next dialog, I’ve selected the Server and Database. I’ve also selected Windows Authentication. Pressing Next causes SQL Packager to run a number of checks and produce a report. Now you’re given a comprehensive list of what is going to be packaged and you’re allowed to change it if you desire. I’ve never made any changes here so I can’t really make any suggestions. The just illustrates the comprehensive nature of so many Red Gate products including this one. Clicking Next gives you still further options. SQL Packager then works its magic and shows you a dialog with the results. Packager then gives you a dialog of the scripts it has generated. The capture above only shows 1 of 4 tabs. Finally pressing Next gives you the option to generate a .NET executable of a C# project. I’ve only generated an executable so I’m not in a position to tell you what the C# project looks like. That may be the subject of further discussions. You can rename the package and tell SQL Packager where to save it. I’ve skipped a lot but this will serve to illustrate the comprehensive (and ingenious) things Red Gate does. All in all, it’s a superb way to distribute populated SQL databases. Oh – we’ll save running the resulting executable for later also but believe me it’s insanely simple.

• Why is the framerate (fps) capped at 60?

  - by dennmat

  ISSUE I recently moved a project from my laptop to my desktop(machine info below). On my laptop the exact same code displays the fps(and ms/f) correctly. On my desktop it does not. What I mean by this is on the laptop it will display 300 fps(for example) where on my desktop it will show only up to 60. If I add 100 objects to the game on the laptop I'll see my frame rate drop accordingly; the same test on the desktop results in no change and the frames stay at 60. It takes a lot(~300) entities before I'll see a frame drop on the desktop, then it will descend. It seems as though its "theoretical" frames would be 400 or 500 but will never actually get to that and only do 60 until there's too much to handle at 60. This 60 frame cap is coming from no where. I'm not doing any frame limiting myself. It seems like something external is limiting my loop iterations on the desktop, but for the last couple days I've been scratching my head trying to figure out how to debug this. SETUPS Desktop: Visual Studio Express 2012 Windows 7 Ultimate 64-bit Laptop: Visual Studio Express 2010 Windows 7 Ultimate 64-bit The libraries(allegro, box2d) are the same versions on both setups. CODE Main Loop: while(!abort) { frameTime = al_get_time(); if (frameTime - lastTime >= 1.0) { lastFps = fps/(frameTime - lastTime); lastTime = frameTime; avgMspf = cumMspf/fps; cumMspf = 0.0; fps = 0; } /** DRAWING/UPDATE CODE **/ fps++; cumMspf += al_get_time() - frameTime; } Note: There is no blocking code in the loop at any point. Where I'm at My understanding of al_get_time() is that it can return different resolutions depending on the system. However the resolution is never worse than seconds, and the double is represented as [seconds].[finer-resolution] and seeing as I'm only checking for a whole second al_get_time() shouldn't be responsible. My project settings and compiler options are the same. And I promise its the same code on both machines. My googling really didn't help me much, and although technically it's not that big of a deal. I'd really like to figure this out or perhaps have it explained, whichever comes first. Even just an idea of how to go about figuring out possible causes, because I'm out of ideas. Any help at all is greatly appreciated. EDIT: Thanks All. For any others that find this to disable vSync(windows only) in opengl: First get "wglext.h". It's all over the web. Then you can use a tool like GLee or just write your own quick extensions manager like: bool WGLExtensionSupported(const char *extension_name) { PFNWGLGETEXTENSIONSSTRINGEXTPROC _wglGetExtensionsStringEXT = NULL; _wglGetExtensionsStringEXT = (PFNWGLGETEXTENSIONSSTRINGEXTPROC) wglGetProcAddress("wglGetExtensionsStringEXT"); if (strstr(_wglGetExtensionsStringEXT(), extension_name) == NULL) { return false; } return true; } and then create and setup your function pointers: PFNWGLSWAPINTERVALEXTPROC wglSwapIntervalEXT = NULL; PFNWGLGETSWAPINTERVALEXTPROC wglGetSwapIntervalEXT = NULL; if (WGLExtensionSupported("WGL_EXT_swap_control")) { // Extension is supported, init pointers. wglSwapIntervalEXT = (PFNWGLSWAPINTERVALEXTPROC) wglGetProcAddress("wglSwapIntervalEXT"); // this is another function from WGL_EXT_swap_control extension wglGetSwapIntervalEXT = (PFNWGLGETSWAPINTERVALEXTPROC) wglGetProcAddress("wglGetSwapIntervalEXT"); } Then just call wglSwapIntervalEXT(0) to disable vSync and 1 to enable vSync. I found the reason this is windows only is that openGl actually doesn't deal with anything other than rendering it leaves the rest up to the OS and Hardware. Thanks everyone saved me a lot of time!

• Unable to determine the provider name for connection of type 'System.Data.SqlServerCe.SqlCeConnectio

  - by Hobbes1312

  Hi, i am using the Ado.Net Entity Framework with Code Only (Tutorial at: ADO.NET team blog) and i want to be as much database independent as possible. In my first approach i just want to go for Sql Express and Sql Compact databases. With Sql Express everthing works fine but with Sql Compact i get the exception mentioned in my question. Does anybody knows if it is possible to connect to Sql Compact with the Code Only approach? (with a generated .edmx file for a Sql Compact database everthing works fine, but i want to use code only!) Here is some code: My Class which is building the DataContext: public class DataContextBuilder : IDataContextBuilder { private readonly DbProviderFactory _factory; public DataContextBuilder(DbProviderFactory factory) { _factory = factory; } #region Implementation of IDataContextBuilder public IDataContext CreateDataContext(string connectionString) { var builder = new ContextBuilder<DataContext>(); RegisterConfiguration(builder); var connection = _factory.CreateConnection(); connection.ConnectionString = connectionString; var ctx = builder.Create(connection); return ctx; } #endregion private void RegisterConfiguration(ContextBuilder<DataContext> builder) { builder.Configurations.Add(new PersonConfiguration()); } } The line var ctx = builder.Create(connection); is throwing the exception. The IDataContext is just a simple Interface for the ObjectContext: public interface IDataContext { int SaveChanges(); IObjectSet<Person> PersonSet { get; } } My connection string is configured in the app.config: <connectionStrings> <add name="CompactConnection" connectionString="|DataDirectory|\Test.sdf" providerName="System.Data.SqlServerCe.3.5" /> </connectionStrings> And the build action is started with var cn = ConfigurationManager.ConnectionStrings["CompactConnection"]; var factory = DbProviderFactories.GetFactory(cn.ProviderName); var builder = new DataContextBuilder(factory); var context = builder.CreateDataContext(cn.ConnectionString);

• Confused with an ASP.NET/WCF WSDL Parsing Error

  - by Vaccano

  I have a WCF Web Service that my ASP.NET app uses. It has been working fine for quite some time. I just added in a Dev Express Grid (and the Dev Express DLLs) and a new page that uses them and now I am getting parsing errors on the WSDL. But the weird part is that it works fine on my machine but fails on the web server machine. (Both are connecting to the same web services WSDL.) Here is the error message I am getting: Server Error in '/MyWebAppWebDev' Application. -------------------------------------------------------------------------------- Parser Error Description: An error occurred during the parsing of a resource required to service this request.

• haskell: a data structure for storing ascending integers with a very fast lookup

  - by valya

  Hello! (This question is related to my previous question, or rather to my answer to it.) I want to store all qubes of natural numbers in a structure and look up specific integers to see if they are perfect cubes. For example, cubes = map (\x -> x*x*x) [1..] is_cube n = n == (head $ dropWhile (<n) cubes) It is much faster than calculating the cube root, but It has complexity of O(n^(1/3)) (am I right?). I think, using a more complex data structure would be better. For example, in C I could store a length of an already generated array (not list - for faster indexing) and do a binary search. It would be O(log n) with lower ?oefficient than in another answer to that question. The problem is, I can't express it in Haskell (and I don't think I should). Or I can use a hash function (like mod). But I think it would be much more memory consuming to have several lists (or a list of lists), and it won't lower the complexity of lookup (still O(n^(1/3))), only a coefficient. I thought about a kind of a tree, but without any clever ideas (sadly I've never studied CS). I think, the fact that all integers are ascending will make my tree ill-balanced for lookups. And I'm pretty sure this fact about ascending integers can be a great advantage for lookups, but I don't know how to use it properly (see my first solution which I can't express in Haskell).

• VS2008 adding SQL Server Database (SQL Server 2008 Mgmt Studio) not working

  - by Kahn

  I'm trying to practice using the ASP.Net MVC at home, but I ran into an impossible problem. I cannot open a connection to SQL Server 2008, I get this error: "Connections to SQL Server files (*.mdf) require SQL Server Express 2005 to function properly. ..." I've googled around for numerous responses, none of them either working or addressing this issue. I'm running Vista 32bit, my SQL Server 2008 Mgmt Studio is also 32bit, I have SP1 installed both on VS2008 Professional, as well as the SQL Server. I changed the machine.config connectionStrings from ./SQLExpress to my SQL Server 2008 name. Now if I connect manually through web.config, in an asp:datasource or code-behind, everything works fine. But for some reason trying to add a DB Connection directly like this always gets the error. This is pretty fatal, since I can't rightly do much unless I can use LINQ to SQL with my MVC test project, and this is the only way I know how. Worked fine in school and work, but not at home. Installing SQL Server Express 2005, as some have suggested, is not an option. Obviously it HAS to work with SQL Server 2008. Thanks in advance.

• Debug Symbols not loading

  - by FunkyFresh84

  I am trying to enable visual studio to step through the .net framework source code when I am debugging. I have tried with both Visual Web-Developer-Express-2010 and Visual-Studio-2011-Express-For-Web and I am getting the same problem with each. When I get to the break point at the .net method I wish to step into I do right-clickstep-into-specificclick-method-to-step-into. Then VS opens a new tab. saying it couldn't find or load the symbols. It gives a list of the assembly symbols it looked for. There is also a 'Load Symbols hyperlink which doesn't work. And another hyperlink that takes me to the debug settings dialog. I have read tutorials on how to set it up and have believe I have the correct settings. In the debugging general settings I have - enable address-level debugging - checked enable source server support - checked enable .net framework source stepping - checked enable just my code - not checked In the debugging symbol settings I have - symbol file (.pdb) locations - Microsoft Symbol Servers - checked Caching Directory - C:\Users\MyAccount\AppData\Local\Temp\SymbolCache Automatically load symbols for: all modules unless excluded - checked Why is it not working? Thank you for your help. edit: here is a screenshot of the error VS is giving me.

• Windows Media Encoder object not created in ASP.NET on MS Server 2003 64 bit

  - by Ron

  Hello, I created (and used) a Windows Media Encoder object in Microsoft Visual C# 2008 Express Edition on MS Server 2003 64 bit. This worked fine. However, when I attempted to create the equivalent Windows Media Encoder object using Microsoft Visual Web Developer 2008 on MS Server 2003 64 bit, the following exception was thrown: "Retrieving the COM class factory for component with CLSID {632B606A-BBC6-11D2-A329-006097C4E476} failed due to the following error: 80040154." It cannot be that the component isn’t registered, because both have a reference to the same WMEncEng.dll file. The Microsoft Visual Web Developer 2008 code also worked fine on XP 32 bit. Could it be a problem with permissions? Regardless, anyone have any ideas why this problem is occurring and, more importantly, how to resolve it? Thank you. Here are the two code snippets from MS Server 2003 64 bit: Microsoft Visual Web Developer 2008 (did not work): using System; using WMEncoderLib; namespace TestWMEnc { public partial class _Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { try { WMEncoder encoder = new WMEncoder(); //exception thrown // ... } catch (Exception err) { string exception = err.Message; } } } } Microsoft Visual C# 2008 Express Edition (worked fine): using System; using System.Windows.Forms; using WMEncoderLib; namespace testWMEncoder { public partial class Form1 : Form { public Form1() { InitializeComponent(); } private void button1_Click(object sender, EventArgs e) { try { WMEncoder encoder = new WMEncoder(); // ... } catch (Exception err) { string exception = err.Message; } } } }

• Complete failure to compile when include CSS Friendly Adapters

  - by david

  Background - I am trying to use the friendly adapters to override the default styling for the standard asp.net menu control that is used by an existing project. The existing project functions normally and compiles when requested without incident. Adding in the code for the for the CSS Friendly adapter and not only does it not compile, but it never even really starts. The Problem in Detail - I am using the sample code from Scott on this page: http://weblogs.asp.net/scottgu/archive/2006/09/08/CSS-Control-Adapter-Toolkit-Update.aspx. The sample project compiles fine, just within the existing project does it fail. Fails without a line number or any other traceable info. It definately appears to be related to the CSSMenuAdapter.browser file, which has been referenced by others online as the cause of similar error. I have tried addind and readding, using as a dll, using as a code file in app code, etc. I am working with aspdotnetstorefront in this case, although it is not unique to them as I have found other references in software packages online. Only thing is, no one ever says what solved the issue. I am using Windows 7, VS2008 Express and SQL Express 2008 R2. The full error msg is: Error 10 Exception of type 'System.OutOfMemoryException' was thrown. Notice that there is no file, line, or column info. Really need some help here. I have been working on this a long time. This really should have tag: cssfriendlyadapter but I could not create that.

• Trouble getting $.ajax() to work in PhoneGap against a locally hosted server

  - by David Gutierrez

  Currently trying to make an ajax post request to an IIS Express hosted MVC 4 Web API end point from an android VM (Bluestacks) on my machine. Here are the snippets of code that I am trying, and cannot get to work: $.ajax({ type: "POST", url: "http://10.0.2.2:28434/api/devices", data: {'EncryptedPassword':'1234','UserName':'test','DeviceToken':'d234'} }).always(function( data, textStatus, jqXHR ) { alert( textStatus ); }); Whenever I run this request I always get back a textStatus of 'error'. After hours of trying different things, I pushed my End Point to an actual server, and was able to actually get responses back in PhoneGap if I built up an XMLHttpRequest by hand, like so: var request = new XMLHttpRequest(); request.open("POST", "http://172.16.100.42/MobileRewards/api/devices", true); request.onreadystatechange = function(){//Call a function when the state changes. console.log("state = " + request.readyState); console.log("status = " + request.status); if (request.readyState == 4) { if (request.status == 200 || request.status == 0) { console.log("*" + request.responseText + "*"); } } } request.send("{EncryptedPassword:1234,UserName:test,DeviceToken:d234}"); Unfortunately, if I try to use $.ajax() against the same end point in the snippet above I still get a status text that says 'error', here is that snippet for reference: $.ajax({ type: "POST", url: "http://172.16.100.42/MobileRewards/api/devices", data: {'EncryptedPassword':'1234','UserName':'test','DeviceToken':'d234'} }).always(function( data, textStatus, jqXHR ) { alert( textStatus ); }); So really, there are a couple of questions here. 1) Why can't I get any ajax calls (post or get) to successfully hit my End Point when it's hosted via IIS Express on the same machine that the Android VM is running? 2) When my end point is hosted on an actual server, through IIS and served through port 80, why can't I get post requests to be successful when I use jquery's ajax calls? (Even though I can get it to work by manually creating an XMLHttpRequest) Thanks

• Oracle why does creating trigger fail when there is a field called timestamp?

  - by Omar Kooheji

  I've just wasted the past two hours of my life trying to create a table with an auto incrementing primary key bases on this tutorial, The tutorial is great the issue I've been encountering is that the Create Target fails if I have a column which is a timestamp and a table that is called timestamp in the same table... Why doesn't oracle flag this as being an issue when I create the table? Here is the Sequence of commands I enter: Creating the Table: CREATE TABLE myTable (id NUMBER PRIMARY KEY, field1 TIMESTAMP(6), timeStamp NUMBER, ); Creating the Sequence: CREATE SEQUENCE test_sequence START WITH 1 INCREMENT BY 1; Creating the trigger: CREATE OR REPLACE TRIGGER test_trigger BEFORE INSERT ON myTable REFERENCING NEW AS NEW FOR EACH ROW BEGIN SELECT test_sequence.nextval INTO :NEW.ID FROM dual; END; / Here is the error message I get: ORA-06552: PL/SQL: Compilation unit analysis terminated ORA-06553: PLS-320: the declaration of the type of this expression is incomplete or malformed Any combination that does not have the two lines with a the word "timestamp" in them works fine. I would have thought the syntax would be enough to differentiate between the keyword and a column name. As I've said I don't understand why the table is created fine but oracle falls over when I try to create the trigger... CLARIFICATION I know that the issue is that there is a column called timestamp which may or may not be a keyword. MY issue is why it barfed when I tried to create a trigger and not when I created the table, I would have at least expected a warning. That said having used Oracle for a few hours, it seems a lot less verbose in it's error reporting, Maybe just because I'm using the express version though. If this is a bug in Oracle how would one who doesn't have a support contract go about reporting it? I'm just playing around with the express version because I have to migrate some code from MySQL to Oracle.

• How 'terse' is too terse? -- Practical guidelines for expressing as much intent in as few characters

  - by Christopher Altman

  First, I love writing as little code as possible. I think, and please correct me, one of the golden rules of programming is to express your code in as few of character as possible while maintaining human readability. But I can get a little carried away. I can pack three or four lines into one statement, something like $startDate = $dateTime > time() ? mktime(0,0,0,date('m',time()-86400),date('d',time()*2),2011) : time(); (Note: this is a notional example) I can comprehend the above code when reading it. I prefer 'mushing' it all together because having less lines per page is a good thing to me. So my question: When writing code and thinking about how compact or terse you can express yourself, what are some guidelines you use? Do you write multiple lines because you think it helps other people? Do you write as little as possible, but use comments? Or do you always look for the way to write as little code as possible and enjoy the rewards of compact statements? (Just one slightly off topic comment: I love the Perl one-liners, but that is not what I am talking about here)

• Adding an ADO.NET Entity Data Model throws build errors

  - by user3726262

  I am using Visual Studio 2013 express. I create a new project and then I add a database to that project. But, when I add an ADO.NET Entity Framework model to that project and then run the program, I get the following four build errors listed below. To try to remedy this myself, I added the namespaces 'System.Data.Entity' and 'System.Data.Entity.Design', but that didn't help. Also, I uninstalled and re-installed the Nuget package. I also uninstalled and re-installed Visual Studio 2013 Express for Windows Desktop. But these measures didn't help the situation either. Please note that I used to use the Entity Data model just fine. But it was around the time that I did a system restore on my computer, and when I updated VS 2013 with an update offered on the start page, and finally, when I signed up for MS Azure, that I started running into the problem described above. Now I would think that uninstalling and reinstalling Visual Studio 2013, and then installing the 'Nuget' Package would solve all problems. What am I missing here? The errors mentioned above are: Error 1 The type or namespace name 'Infrastructure' does not exist in the namespace 'System.Data.Entity' (are you missing an assembly reference?) C:\Users\John\documents\visual studio 2013\Projects\Riches\Riches\RichesModel.Context.cs 14 30 DataLayer Error 2 The type or namespace name 'DbContext' could not be found (are you missing a using directive or an assembly reference?) C:\Users\John\documents\visual studio 2013\Projects\Riches\Riches\RichesModel.Context.cs 16 52 DataLayer Error 3 The type or namespace name 'DbModelBuilder' could not be found (are you missing a using directive or an assembly reference?) C:\Users\John\documents\visual studio 2013\Projects\Riches\Riches\RichesModel.Context.cs 23 49 DataLayer Error 4 The type or namespace name 'DbSet' could not be found (are you missing a using directive or an assembly reference?) C:\Users\John\documents\visual studio 2013\Projects\Riches\Riches\RichesModel.Context.cs 28 16 DataLayer Thank you and I realize that my last attempt at this question was rather rough-draftish, John

• Another rsAccessDenied problem with SSRS

  - by Rich.Carpenter

  I've read through a lot of posts regarding the problem, but none of the proposed solutions have worked for me. I continue to get an error stating, "The permissions granted to user '\Rich' are insufficient for performing this operation. (rsAccessDenied)." If I am logged in as the local administrator account, entering the Reporting Services URL in IE doesn't give me that error, but it takes me to a blank page. I haven't been able to get to a SSRS home page at all. Order of operations: I installed and patched Windows 7 Ultimate 64-bit I installed SQL Server Express 2008 with Advanced Services using the MS web installer. I downloaded and installed SP1 for SQL Server Express 2008. I've tried running IE as administrator, adding local machine to trusted sites, and just about every other suggestion I've found. I even ran the entire installation logged in as the local administrator. Nothing seems to work. Could someone please tell me, considering the above installation process, what I should expect to do after to make this work?

• MSSQL in ASP.NET application getting unstable after a certain period

  - by Barslett

  Hello, I have an ASP.NET 2.0 application that I made to keep track of disruption reports about our public transport system. The architecture is pretty straight-forward; an MSSQL Express 2008 database, ADO.NET and a DataSet/DAL with a few methods to access the database. There is a set of .aspx pages for the UI in use by our dispatchers and on our public website, as well as a set of SOAP and REST webservices and an RSS feed. Everything worked just fine for more than a year, until two weeks ago. Now and then, it seems as the database enters an unstable mode, and the application starts responding something right, something wrong. The typical error is that apparently, an empty DataTable is returned to the public disruption overview or to the RSS generator. Thus, the user gets e.g. an empty GridView, but no exception is thrown AFAIK, and nothing is written to the Windows Application log. After a restart of the MSSQL Express service, the situation is back to normal. It has to be said that the situation first time appeared a few days after I made a new minor upgrade of the application. The RSS generator was slightly rewritten, and I added a WCF REST service. But the DAL and the database schema were untouched... Any hints of how we could keep the database stable? It is a bit annoying not to have a clue ;-)

• Deploying ASP.Net MVC application

  - by a_m0d

  I've recently reached the stage where an ASP.net MVC application I am developing is ready to be deployed to the production server. I've worked out how to publish the application - I've got all the files on the server, and can access them over the internet. However, I can't work out how to deploy my database. The server has the SQL Server Management Studio Express installed, as the database used is a SQL Server Express database. I have the server instance up and running - I just don't know how to add the tables, etc. to the database. I have created the "CREATE TABLE" scripts on the development machine, but as far as I can see, Management Studio does not provide any way to actually run these scripts. I have looked through all the menu items that I could see, and none of them worked. Even using the "Create new query..." option and pasting the script in didn't work. When I try "File-Open..." and select a script to run, set the correct database from the dropdown list on the toolbar, and then execute the script, it complains about not finding the database file (even when I set the USE [...] statement to the correct path. Deleting the USE [...] statement, the script complains that it can't find the [dbo].[Invoices] object; however, it shouldn't be able to find it, because its trying to create it! tl;dr: What's the best way to make sure that the database on the production machine matches the database on my development machine?

• What .NET reporting tools are best for dynamic report generation?

  - by bvanderw

  Perhaps I need to define "dynamic generation". By this I mean using graphics primitives to draw on the page (such as DrawText or DrawLine, etc) This is what System.Drawing.Printing provides. I often need to create forms and reports for Windows applications that either require dynamic generation or where I need control over the formatting that stretches or goes beyond the capabilities of most report designers. Essentially, I need to ability to create my own pages using graphics primitives like you can do with System.Drawing.Printing that are part of package that also provides a report designer, exporting to PDF, etc. In my Delphi days, I used Rave Reports (along with the exporting add-ons from Gnostice) because it was the only Delphi reporting tool that gave you that kind of fine control. I've been struggling with the reporting tools provided by Developer Express and I have given up trying to make them do what I need to do. I downloaded a trial of ActiveReports and was able to completely create one of my dynamic reports (using their Page class) in a few hours one afternoon. It's likely I will buy their product, but it's a bit frustrating to have to do so after investing in the Developer Express tools. Before I do so, are there any other products that offer this functionality that I should investigate? As far as I can tell, Crystal Reports does not - is this correct? Thanks.... --Bruce

• ASP.NET web form Routing issue via UNC Path

  - by Slash

  I create a IIS 7.0 website via UNC path to load .aspx to dynamic compile files and runs. however, it's running perfect. I always use IIS URL Rewrite module 2 to rewrite my site URL n' its perfect, too. Today, I wanna use System.Web.Routing to implement url rewrite but I encountered difficulties... When I wrote code in Global.asax: System.Web.Routing.RouteTable.Routes.MapPageRoute("TEST", "AAA/{prop}", "~/BBB/CCC.aspx"); And it just CANNOT reDirect to /BBB/CCC.aspx When I type the URL(like: xx.xx.xx.xx/BBB/CCC.aspx) in browser directly, it runs normally that I want. (so it proof CCC.aspx is in right path.) thus, I copy all of the code and open VS2010 running with IIS 7.5 Express locally, it works perfect! e.g: in browser URL I type xx.xx.xx.xx/AAA/1234, it will turn to page xx.xx.xx.xx/BBB/CCC.aspx (Works perfect!) Why??? help me plz. thanks. Update: I think I should consider not UNC path to make it error! when I move all code to physical disk and setup IIS 7.0 to monitor this Folder, it still not works! But the same code run in VS2010 + IIS 7.5 Express it works!? so strange!

• CREATE VIEW called multiple times not creating all views

  - by theninepoundhammer

  Noticing strange behavior in SQL 2005, both Express and Enterprise Edition: In my code I need to loop through a series of values (about five in a row), and for each value, I need to insert the value into a table and dynamically create a new view using that value as part of the where clause and the name of the view. The code runs pretty quickly, but what I'm noticing is that all the values are inserted into the table correctly but only the LAST view is being created. Every time. For example, if the values I'm using are X1, X2, X3, X4, and X5, I'll run the process, open up Mgmt Studio, and see five rows in the table with the correct five values, but only one view named MyView_x5 that has the correct WHERE clause. At first, I had this loop in an SSIS package as part of a larger data flow. When I started noticing this behavior, I created a stored proc that would create the CREATE VIEW statement dynamically after the insert and called EXECUTE to create the view. Same result. Finally, I created some C# code using the Enterprise Library DAAB, and did the insert and CREATE VIEW statements from my DLL. Same result every time. Most recently, I turned on Profiler while running against the Enterprise Edition and was able to verify that the Batch Started and Batch Completed events were being fired off for each instance of the view. However, like I said, only the last view is actually being created. Does anyone have any idea why this might be happening? Or any suggestions about what else to check or profile? I've profiled for error messages, exceptions, etc. but don't see any in my trace file. My express edition is 9.00.1399.06. Not sure about the Enterprise edition but think it is SP2.

• Deployment of SQL Server: installing a second instance?

  - by Workshop Alex

  Simple problem. I'm working on a Delphi 2007/WIN32 application which now uses MS Access as simple data store. I have to modify it to support SQL Server Express, which is easy. These modifications are working so the application can be deployed using either SQL Server or MS Access. (Whatever the user prefers.) I did consider deploying the whole application together with the SQL Compact but this is not practicak. Using SQL Server Express 2008 instead of 2005 is an option, but also has a few nasty side-effects which we don't want to resolve for now. The problem is deploying the whole project. The installation with SQL Server would need a quiet installation so the user won't notice it. SQL Server is mentioned in the documentation so they know it's there. We just don't want to bother them with technical issues. In most cases, such an installation will go just fine. But what if the user already has an SQL Server (2005) installation which is used for something else? Personally, I would prefer to just install a second instance of SQL Server on their system so it won't conflict with the other installation. (Thus, if they uninstall the other app, the SQL instance will just stay installed.) While SQL Server 2005 and 2008 can be installed on the same system simply by using two different names for the instance, I wonder if it's also possible to install SQL Server 2005 twice on a single system to get two instances. And if possible, how?

• winUserControl in VS2010 - properties are not visible in designer

  - by mj82

  I have a problem with (I suppose) my Visual Studio 2010 Express environment: when I design my own UserControl, in Properties grid I can't see public properties of that control. They are however visible in the project, that reference this control. As it's Express Edition, I create new empty project, then add new UserControl to it. Then, for a test, I put following code: using System; using System.Collections.Generic; using System.ComponentModel; using System.Drawing; using System.Data; using System.Linq; using System.Text; using System.Windows.Forms; namespace Project1 { public partial class UserControl1 : UserControl { private int myNumber; [Browsable(true)] public int MyNumber { get { return myNumber; } set { myNumber = value; } } public UserControl1() { InitializeComponent(); } } } In VS 2008, as I remember, that should be enogh to show MyNumber property in Properties grid, even without [Browsable(true)] attribute. In VS 2010 however, when I double click UserControl1.cs in Solution Explorer and look in Properties, I don't see MyNumber. When I reference and use this control in another project, there is an access to it's properties. I've tried to competly reinstall VS 2010 environment, including SP1, but with no success. Do you have any idea what can be wrong? By the way: none of these attributes are working, either: [Browsable(true)] [EditorBrowsable(EditorBrowsableState.Always)] [DesignerSerializationVisibility(DesignerSerializationVisibility.Content)] [Bindable(true)] Best regards, Marcin
