• mod_cgi , mod_fastcgi, mod_scgi , mod_wsgi, mod_python, FLUP. I don't know how many more. what is mo

  - by claws

  I recently learnt Python. I liked it. I just wanted to use it for web development. This thought caused all the troubles. But I like these troubles :) Coming from PHP world where there is only one way standardized. I expected the same and searched for python & apache. http://stackoverflow.com/questions/449055/setting-up-python-on-windows-apache says Stay away from mod_python. One common misleading idea is that mod_python is like mod_php, but for python. That is not true. So what is equivalent of mod_php in python? I need little clarification on this one http://stackoverflow.com/questions/219110/how-python-web-frameworks-wsgi-and-cgi-fit-together CGI, FastCGI and SCGI are language agnostic. You can write CGI scripts in Perl, Python, C, bash, or even Assembly :). So, I guess mod_cgi , mod_fastcgi, mod_scgi are their corresponding apache modules. Right? WSGI is some kind of optimized/improved inshort an efficient version specifically designed for python language only. In order to use this mod_wsgi is a way to go. right? This leaves out mod_python. What is it then? Apache - mod_fastcgi - FLUP (via CGI protocol) - Django (via WSGI protocol) Flup is another way to run with wsgi for any webserver that can speak FCGI, SCGI or AJP What is FLUP? What is AJP? How did Django come in the picture? These questions raise quetions about PHP. How is it actually running? What technology is it using? mod_php & mod_python what are the differences? In future if I want to use Perl or Java then again will I have to get confused? Kindly can someone explain things clearly and give a Complete Picture.

• How to configure outgoing connections from an SQL stored procedure?

  - by Peter Vestberg

  I am working on a .NET project which uses Microsoft SQL server. In this project, I need a CLR stored procedure (written in C#) that uses a remote web service. So, when the stored procedure is executed on the SQL server, it makes web service calls and thus sends packets to a remote location. The problem is that when executing the SP I get: "System.Net.WebException: The request failed with HTTP status 403: Forbidden." The database user has full permission, the deployed CLR assembly and SP are even marked "unsafe", I tried signing it etc., so any of that is not causing the problem. When I am executing the very same C# code, but from a simple console application instead of as a SP, it all works fine. So I started to suspect a network related problem and had a packet sniffer running when executing both the SP and the console app version. What I realized was that the packets sent out had different destination IP addresses: the console app sent the packets directly to the web service IP while the SP sent the packets to a proxy server we use in our company. Due to network policies the latter is not allowed and that explains the "403 Forbidden" exception. So my question boils down to this: How can I configure the SP/MS SQL server to NOT use that proxy? I want it to send the packets directly to the web service IP, just like the test console app. (again, the C# code is the same , so it's not a programming matter). I've disabled all proxy settings in Internet Explorer in case the SQL server inherits these settings or something. However, no luck. Any help would be greatly appreciated! Best regards, Peter

• Expression Blend doesn't recognize comand objects declared in code behind file

  - by Brian Ensink

  I have a WPF UserControl. The code behind file declares some RoutedUICommand objects which are referenced in the XAML. The application builds and runs just fine. However Expression Blend 3 cannot load the XAML in the designer and gives errors like this one: The member "ResetCameraComand" is not recognized or accessible. The class and the member are both public. Building and rebuilding the project in Blend and restarting Blend hasn't helped. Any ideas what the problem is? Here are fragments of my XAML ... <UserControl x:Class="CAP.Visual.CameraAndLightingControl" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:CAP.Visual;assembly=VisualApp" Height="100" Width="700"> <UserControl.CommandBindings> <CommandBinding Command="local:CameraAndLightingControl.ResetCameraCommand" Executed="ResetCamera_Executed" CanExecute="ResetCamera_CanExecute"/> </UserControl.CommandBindings> .... ... and the code behind C# namespace CAP.Visual { public partial class CameraAndLightingControl : UserControl { public readonly static RoutedUICommand ResetCameraCommand; static CameraAndLightingControl() { ResetCameraCommand = new RoutedUICommand("Reset Camera", "ResetCamera", typeof(CameraAndLightingControl)); }

• Alternatives to using web.config to store settings (for complex solutions)

  - by Brian MacKay

  In our web applications, we seperate our Data Access Layers out into their own projects. This creates some problems related to settings. Because the DAL will eventually need to be consumed from perhaps more than one application, web.config does not seem like a good place to keep the connection strings and some of the other DAL-related settings. To solve this, on some of our recent projects we introduced a third project just for settings. We put the setting in a system of .Setting files... With a simple wrapper, the ability to have different settings for various enviroments (Dev, QA, Staging, Production, etc) was easy to achieve. The only problem there is that the settings project (including the .Settings class) compiles into an assembly, so you can't change it without doing a build/deployment, and some of our customers want to be able to configure their projects without Visual Studio. So, is there a best practice for this? I have that sense that I'm reinventing the wheel. Some solutions such as storing settings in a fixed directory on the server in, say, our own XML format occurred to us. But again, I would rather avoid having to re-create encryption for sensitive values and so on. And I would rather keep the solution self-contained if possible. EDIT: The original question did not contain the really penetrating reason that we can't (I think) use web.config ... That puts a few (very good) answers out of context, my bad.

• Can protobuf-net serialize this combination of interface and generic collection?

  - by tsupe

  I am trying to serialize a ItemTransaction and protobuf-net (r282) is having a problem. ItemTransaction : IEnumerable<KeyValuePair<Type, IItemCollection>></code> and ItemCollection is like this: FooCollection : ItemCollection<Foo> ItemCollection<T> : BindingList<T>, IItemCollection IItemCollection : IList<Item> where T is a derived type of Item. ItemCollection also has a property of type IItemCollection. I am serializing like this: IItemCollection itemCol = someService.Blah(...); ... SerializeWithLengthPrefix<IItemCollection>(stream, itemCol, PrefixStyle.Base128); My eventual goal is to serialize ItemTransaction, but am snagged with IItemCollection. Item and it's derived types can be [de]serialized with no issues, see [1], but deserializing an IItemCollection fails (serializing works). ItemCollection has a ItemExpression property and when deserializing protobuf can't create an abstract class. This makes sense to me, but I'm not sure how to get through it. ItemExpression<T> : ItemExpression, IItemExpression ItemExpression : Expression ItemExpression is abstract as is Expression How do I get this to work properly? Also, I am concerned that ItemTransaction will fail since the IItemCollections are going to be differing and unknown at compile time (an ItemTransaction will have FooCollection, BarCollection, FlimCollection, FlamCollection, etc). What am I missing (Marc) ? [1] http://stackoverflow.com/questions/2276104/protobuf-net-deserializing-across-assembly-boundaries

• Running multiple applications in STM32 flash

  - by Richard

  Hey! I would like to have two applications in my STM32 flash, one is basically a boot and the other the 'main' application. I have figured out how to load each of them into different areas of flash, and after taking a memory dump everything looks like it is in the right place. So when I do a reset it loads the boot, all the boot does at the moment is jump to the application. Debugging the boot, this all appears to work correctly. However the problems arrives after i've made the jump to the application, it just executes one instruction (assembly) and then jumps back to the boot. It should stay in the application indefinitely. My question is then, where should I 'jump' to in the app? It seems that there are a few potential spots, such as the interrupt vectors, the reset handler, the main function of the app. Actually I've tried all of those with no success. Hopefully that makes sense, i'll update the question if not. thanks for your help! Richard Updates: I had a play around in the debugger and manually changed the program counter to the main of the application, and well that worked a charm, so it makes me think there is something wrong with my jump, why doesn't the program counter keep going after the jump? Actually it seems to be the PSR, the 'T' gets reset on the jump, if I set that again after the jump it continues on with the app as I desire Ok found a solution, seems that you need to have the PC LSB set to 1 when you do a branch or it falls into the 'ARM' mode (32 bit instruction instead of 16 bit instructions like in the 'thumb' mode. Quite an obscure little problem, thanks for letting me share it with you!

• System.Windows.Forms.DataVisualization Namespace Fine in One Class but Not in Another

  - by jxpx777

  Hi. I'm getting this error The type or namespace name 'DataVisualization' does not exist in the namespace 'System.Windows.Forms' (are you missing an assembly reference?) Here is my using section of the class: using System; using System.Collections; using System.Collections.Generic; using System.Windows.Forms.DataVisualization.Charting; using System.Windows.Forms.DataVisualization.Charting.Borders3D; using System.Windows.Forms.DataVisualization.Charting.ChartTypes; using System.Windows.Forms.DataVisualization.Charting.Data; using System.Windows.Forms.DataVisualization.Charting.Formulas; using System.Windows.Forms.DataVisualization.Charting.Utilities; namespace myNamespace { public class myClass { // Usual class stuff } } The thing is that I am using the same DataVisualization includes in another class. The only thing that I can think that is different is that the classes that are giving this missing namespace error are Solution Items rather than specific to a project. The projects reference them by link. Anyone have thoughts on what the problem is? I've installed the chart component, .Net 3.5 SP1, and the Chart Add-in for Visual Studio 2008. UPDATE: I moved the items from Solution Items to be regular members of my project and I'm still seeing the same behavior. UPDATE 2: Removing the items from the Solution Items and placing them under my project worked. Another project was still referencing the files which is why I didn't think it worked previously. I'm still curious, though, why I couldn't use the namespace when the classes were Solution Items but moving them underneath a project (with no modifications, mind you) instantly made them recognizable. :\

• C# compiler error CS0006: metadata file is not found

  - by Rob

  I've built a c# compiler using the tutorial on MSDN and a few other resources including here, and I've gotten it to work until I add additional reference assemblies. My errors stem from adding "System.dll" and "System.Windows.Forms.dll" to the ReferenceAssemblies list. here's my code: private void SetUpCompilingParameters() { string ver = string.Format("{0}.{1}.{2}", Environment.Version.Major, Environment.Version.MajorRevision, Environment.Version.Build); string libDir = string.Format(@"{0}", Environment.CurrentDirectory); string raDir = @"C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.0"; string exWpfDir = string.Format(@"C:\WINDOWS\Microsoft.NET\Framework\v{0}\WPF", ver); string exDir = string.Format(@"C:\WINDOWS\Microsoft.NET\Framework\v{0}", ver); MyCompiler = new CSharpCodeProvider(); CompilingParam = new CompilerParameters(); CompilingParam.GenerateExecutable = false; CompilingParam.GenerateInMemory = true; CompilingParam.IncludeDebugInformation = false; CompilingParam.TreatWarningsAsErrors = false; CompilingParam.CompilerOptions = string.Format("/lib:{0}", libDir); CompilingParam.CompilerOptions = string.Format("/lib:{0}", raDir); CompilingParam.CompilerOptions = string.Format("/lib:{0}", exDir); //CompilingParam.CompilerOptions = string.Format("/lib:{0}", exWpfDir); CompilingParam.ReferencedAssemblies.Add("System.dll"); CompilingParam.ReferencedAssemblies.Add("System.Windows.Forms.dll"); } As you can see, I've explicitly referenced directories in CompilerOptions but its not helping. I'd like to test the solution on here on stackoverflow that utilizes: CompilingParam.ReferencedAssemblies.Add(typeof(System.Xml.Linq.Extensions).Assembly.Location); but I'm having trouble using it for the general System.dll etc...

• searching for a programming platform with hot code swap

  - by Andreas

  I'm currently brainstorming over the idea how to upgrade a program while it is running. (Not while debugging, a "production" system.) But one thing that is required for it, is to actually submit the changed source code or compiled byte code into the running process. Pseudo Code var method = typeof(MyClass).GetMethod("Method1"); var content = //get it from a database (bytecode or source code) SELECT content FROM methods WHERE id=? AND version=? method.SetContent(content); At first, I want to achieve the system to work without the complexity of object-orientation. That leads to the following requirements: change source code or byte code of function drop functions add new functions change the signature of a function With .NET (and others) I could inject a class via an IoC and could thus change the source code. But the loading would be cumbersome, because everything has to be in an Assembly or created via Emit. Maybe with Java this would be easier? The whole ClassLoader is replacable, I think. With JavaScript I could achieve many of the goals. Simply eval a new function (MyMethod_V25) and assign it to MyClass.prototype.MyMethod. I think one can also drop functions somehow with "del" Which general-purpose platform can handle such things?

• Why won't VS2010 RC use my existing types when I add a service reference?

  - by Johan Driessen

  I have a huge problem getting services references in VS2010 RC to use existing assemblies. Even though I have a class library with all the data contracts (classes marked with DataContract and properties with DataMember) that is shared between the service project and the consuming project (which is a class library), when I add a service reference, the data contracts are regenerated withing the service reference instead of using the existing types. When I was using VS2010 beta 2, this worked fine, and I have existing service references using the very same data contracts. But if I add a new service reference, or even update an old one, it won't use the existing types anymore. I have made a mini-test-solution, with one service, one data contract type and one console app as a consumer (all in the same solution), and there it seems to work, but that's no great comfort to me. Is there any way to see why it can't use the existing types? Edit to clearify. It works to generate the proxy classes with svcutil.exe, and point to the data contracts dll, like this: svcutil.exe http://localhost/MyService.svc /reference:[Path To DataContracts]\DataContracts.dll /n:*,MyProject.MyServiceReference /ct:System.Collections.Generic.List`1 The question is, what possible reason could there be for Visual Studio to generate its own datacontracts instead of using the existing ones even though the "reuse" checkbox is checked and the datacontracts assembly is referenced.

• WPF deployment strategy dilemma.clickonce(limited customization)+autoupdate vs installer(unlimited c

  - by black sensei

  Hello Experts!!! I've been facing a deployment problem.I've built a WPF application with visual studio 2008 and created an installer(msi) which works fine.But then it's pain to add automatic update to it. i've seen this article at windowsclient.net but it seems to be pretty old but could have been the perfect thing for me.Then i looked at the .Net Application updater block v2.0 which uses enterprise library june 2005 and for some reason it's not installing on my machine. I thought i will need to use a more recent Enterprise library so i installed and compiled Enterprise 4.1(october 2008) but nothing better happened.To i decided to give a try to CLickonce deployment.After struggling with it, it was almost perfect.I realized that when i was testing the updates provided by the clickonce on my machine which is XP i didn't notice the need of having sqlite dll in the GAC. surely it was already there.I noticed it when i moved to vista that there is a problem.After checking the net i know it's impossible to add a dll to the Global Assembly Cache. Now i'm stuck, i think i've hit a wall.Can any one share some of his experience? I'm willing to try the updater block if i can get help. Thanks for reading this!!

• Missing Intellisense While Describing Custom Control Properties Declaratively

  - by Albert Bori

  So, I've been working on this project for a few days now, and have been unable to resolve the issue of getting intellisense support for my custom-defined inner properties for a user control (ascx, mind you). I have seen the solution to this (using server controls, .cs mind you) many times. Spelled out in this article very well. Everything works for me while using ascx controls except intellisense. Here's the outline of my code: [PersistChildren(true)] [ParseChildren(typeof(BreadCrumbItem))] [ControlBuilder(typeof(BreadCrumbItem))] public partial class styledcontrols_buttons_BreadCrumb : System.Web.UI.UserControl { ... [PersistenceMode(PersistenceMode.InnerDefaultProperty)] public List<BreadCrumbItem> BreadCrumbItems { get { return _breadCrumbItems; } set { _breadCrumbItems = value; } } ... protected override void AddParsedSubObject(object obj) { base.AddParsedSubObject(obj); if (obj is BreadCrumbItem) BreadCrumbItems.Add(obj as BreadCrumbItem); } ... public class BreadCrumbItem : ControlBuilder { public string Text { get; set; } public string NavigateURL { get; set; } public override Type GetChildControlType(string tagName, System.Collections.IDictionary attribs) { if (String.Compare(tagName, "BreadCrumbItem", true) == 0) { return typeof(BreadCrumbItem); } return null; } } } Here's my mark up (which works fine, just no intellisense on the child object declarations): <%@ Register src="../styledcontrols/buttons/BreadCrumb.ascx" tagname="BreadCrumb" tagprefix="uc1" %> ... <uc1:BreadCrumb ID="BreadCrumb1" runat="server" BreadCrumbTitleText="Current Page"> <BreadCrumbItem Text="Home Page" NavigateURL="~/test/breadcrumbtest.aspx?iwentsomewhere=1" /> <BreadCrumbItem Text="Secondary Page" NavigateURL="~/test/breadcrumbtest.aspx?iwentsomewhere=1" /> </uc1:BreadCrumb> I think the issue lies with how the intellisense engine traverses supporting classes. All the working examples I see of this are not ascx, but Web Server Controls (cs, in a compiled assembly). If anyone could shed some light on how to accomplish this with ascx controls, I'd appreciate it.

• How can I reuse .NET resources in multiple executables?

  - by Brandon

  I have an existing application that I'm supposed to take and create a "mini" version of. Both are localized apps and we would like to reuse the resources in the main application as is. So, here's the basic structure of my apps: MainApplication.csproj /Properties/Resources.resx /MainUserControl.xaml (uses strings in Properties/Resources.resx) /MainUserControl.xaml.cs MiniApplication.csproj link to MainApplication/Properties/Resources.resx link to MainApplication/MainUserControl.xaml link to MainApplication/MainUserControl.xaml.cs MiniApplication.xaml (tries to use MainUserControl from MainApplication link) So, in summary, I've added the needed resources and user control from the main application as links in the mini application. However, when I run the mini application, I get the following exception. I'm guessing it's having trouble with the different namespaces, but how do I fix? Could not find any resources appropriate for the specified culture or the neutral culture. Make sure \"MainApplication.Properties.Resources.resources\" was correctly embedded or linked into assembly \"MiniApplication\" at compile time, or that all the satellite assemblies required are loadable and fully signed. FYI, I know I could put the user control in a user control library but the problem is that the mini application needs to have a small footprint. So, we only want to include what we need.

• Can I get a reference to a pending transaction from a SqlConnection object?

  - by Rune

  Hey, Suppose someone (other than me) writes the following code and compiles it into an assembly: using (SqlConnection conn = new SqlConnection(connString)) { conn.Open(); using (var transaction = conn.BeginTransaction()) { /* Update something in the database */ /* Then call any registered OnUpdate handlers */ InvokeOnUpdate(conn); transaction.Commit(); } } The call to InvokeOnUpdate(IDbConnection conn) calls out to an event handler that I can implement and register. Thus, in this handler I will have a reference to the IDbConnection object, but I won't have a reference to the pending transaction. Is there any way in which I can get a hold of the transaction? In my OnUpdate handler I want to execute something similar to the following: private void MyOnUpdateHandler(IDbConnection conn) { var cmd = conn.CreateCommand(); cmd.CommandText = someSQLString; cmd.CommandType = CommandType.Text; cmd.ExecuteNonQuery(); } However, the call to cmd.ExecuteNonQuery() throws an InvalidOperationException complaining that "ExecuteNonQuery requires the command to have a transaction when the connection assigned to the command is in a pending local transaction. The Transaction property of the command has not been initialized". Can I in any way enlist my SqlCommand cmd with the pending transaction? Can I retrieve a reference to the pending transaction from the IDbConnection object (I'd be happy to use reflection if necessary)?

• HtmlAgilityPack - Vs 2010 - c# ASP - File Not found

  - by Janosch Geigowskoskilu

  First, I've already searched the web & StackOverflow for hours, and i did find a lot about troubleshooting HtmlAgilityPack and tried most of these but nothing worked. The Situation: I'm developing a C# ASP .NET WebPart in SharePoint Foundation. Everything works fine, now I want to Parse a HTML Page to get all ImagePaths and save the Images on HD/Temp. To do that I was downloading HtmlAgilityPack, current version, add reference to Project, everything looks OK, IntelliSense works fine. The Exception: But when I want to run the section where HtmlAgilityPack should be used my Browser shows me a FileNotFoundException - The File or Assembly could not be found. What I tried: After first searches i tried to include v1.4.0 of HtmlAgilityPack cause I read that the current version in some case is not really stable. This works fine to until the point I want to use HtmlAgilityPack, the same Exception. I also tried moving the HtmlAgilityPack direct to the Solution directory, nothing changed. I tried to insert HtmlAgilityPack via using and I tried direct call e.g. HtmlAgilityPack.HtmlDocument. Conclusion : When I compile no error occurs, the reference is set correct. When I trace the HtmlAgilityPack.dll with ProcMon the Path is shown correct, but sometimes the Result is 'File Locked with only Readers' but I don't know enough about ProcMon to Know what this means or if this is critical. It couldn't have something to do with File Permissions because if I check the DLL the permissions are all given.

• Simple Enterprise Library console application refuses to compile

  - by Vadim

  I just downloaded and installed Microsoft Enterprise Library 5.0. I fired up VS 2010 to play with EL 5 and created a very simple console application. However, it would not compile. I got the following error: The type or namespace name 'Data' does not exist in the namespace 'Microsoft.Practices.EnterpriseLibrary' (are you missing an assembly reference?) I added Microsoft.Practices.EnterpriseLibrary.Common, Microsoft.Practices.EnterpriseLibrary.Data, and Microsoft.Practices.Unity references to my project. Here's the simple code that refuses to compile. using Microsoft.Practices.EnterpriseLibrary.Common.Configuration.Unity; using Microsoft.Practices.EnterpriseLibrary.Data; using Microsoft.Practices.Unity; namespace EntLib { class Program { static void Main(string[] args) { IUnityContainer container = new UnityContainer(); container.AddNewExtension<EnterpriseLibraryCoreExtension>(); var defaultDatabase = container.Resolve<Database>(); } } } The error above complains about line #2 : using Microsoft.Practices.EnterpriseLibrary.Data; Someone probably will point out to a stupid mistake by me, but at the moment I fail to see it. I tried to remove and add again Microsoft.Practices.EnterpriseLibrary.Data to refences but it didn't help.

• C#: How to run NUnit from my code

  - by Flavio

  Hello, I'd like to use NUnit to run unit tests in my plug-in, but it needs to be run in the context of my application. To solve this, I was trying to develop a plug-in that runs NUnit, which in turn will execute my tests in the application's context. I didn't find a specific documentation on this subject so I dug a piece of information here and there and I came out with the following piece of code (which is similar to one I found here in StackOverflow): SimpleTestRunner runner = new SimpleTestRunner(); TestPackage package = new TestPackage( "Test" ); string loc = Assembly.GetExecutingAssembly().Location package.Assemblies.Add( loc ); if( runner.Load(package) ) { TestResult result = runner.Run( new NullListener() ); } The result variable says "has no TestFixture" although I know for sure it is there. In fact my test file contains two test. Using another approach I found, which is summarized by the following code: TestSuiteBuilder builder = new TestSuiteBuilder(); TestSuite testSuite = builder.Build( package ); // Run tests TestResult result = testSuite.Run( new NullListener(), NUnit.Core.TestFilter.Empty ); I saw nunit data structures with only 1 test and I had the same error. For sake of completeness, I am using the latest version of nunit, which is 2.5.5.10112. Does anyone know what I'm missing? A sample code would be appreciated. thanks

• NHibernate stored procedure problem

  - by Calvin

  I'm having a hard time trying to get my stored procedure works with NHibernate. The data returned from the SP does not correspond to any database table. This is my mapping file: <?xml version="1.0" encoding="utf-8" ?> <hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" assembly="DomainModel" namespace="DomainModel.Entities"> <sql-query name="DoSomething"> <return class="SomeClass"> <return-property name="ID" column="ID"/> </return> exec [dbo].[sp_doSomething] </sql-query> </hibernate-mapping> Here is my domain class: namespace DomainModel.Entities { public class SomeClass { public SomeClass() { } public virtual Guid ID { get; set; } } } When I run the code, it fails with Exception Details: NHibernate.HibernateException: Errors in named queries: {DoSomething} at line 80 Line 78: config.Configure(Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "NHibernate.config")); Line 79: Line 80: g_sessionFactory = config.BuildSessionFactory(); When I debug into NHibernate code, it seems that SomeClass is not added to the persister dictionary because there isn't a class mapping (only sql-query) defined in hbm.xml. And later on in CheckNamedQueries function, it is not able to find the persistor for SomeClass. I've checked all the obvious things (e.g. make hbm as an embedded resource) and my code isn't too much different from other samples I found on the web, but somehow I just can't get it working. Any idea how I can resolve this issue?

  - by Mr. Flint

  ------Using VS2008, ASP.Net with C#, Oracle, NHibernate---- I have tested my stored procedure. It's working but not with NHibernate. Here are the codes: Procedure : create or replace procedure ThanaDelete (id number) as begin delete from thana_tbl where thana_code = id; end Mapping File: <?xml version="1.0" encoding="utf-8" ?> <hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" assembly="DataTransfer" namespace="DataTransfer"> <class name="DataTransfer.Models.Thana, DataTransfer" table="THANA_TBL"> <id name="THANA_CODE" column="THANA_CODE" type="Int32" unsaved-value="0"> <generator class="native"> <param name="sequence"> SEQ_TEST </param> </generator> </id> <property name="THANA_NAME" column="THANA_NAME" type="string" not-null="false"/> <property name="DISTRICT_CODE" column="DISTRICT_CODE" type="Int32" not-null="false"/> <property name="USER_ID" column="USER_ID" type="string" not-null="false"/> <property name="TRANSACTION_DATE" column="TRANSACTION_DATE" type="Date" not-null="false"/> <property name="TRANSACTION_TIME" column="TRANSACTION_TIME" type="string" not-null="false"/> <sql-delete>exec THANADELETE ? </sql-delete> </class> </hibernate-mapping> error: Message: could not delete: [DataTransfer.Models.Thana#10][SQL: exec THANADELETE ?] Source: NHibernate Inner Exception System.Data.OracleClient.OracleException Message: ORA-00900: invalid SQL statement

• How to specify path for file from different project in WPF?

  - by MartyIX

  Hello, I've got two projects in WPF and one project is the main one and the second one is just for testing (it uses files of the main project - files are added via Project - add - Existing items... - selected file - add as link so that the file is only in the main project really). Folders with projects are these: C:\Work\...\Projects\Main C:\Work\...\Projects\XXXTestProject where XXX stands for different parts of the Main project which I test separately. I've got the code: <Window x:Class="Sokoban.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:Sokoban" xmlns:diag="clr-namespace:System.Diagnostics;assembly=WindowsBase" Title="Window1" Height="559" Width="419"> <Window.Resources> <ResourceDictionary> <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="GameDesk.xaml" /> </ResourceDictionary.MergedDictionaries> </ResourceDictionary> </Window.Resources> <Grid> <Rectangle local:GameDeskProperties.FieldSize="30" Name="myrect" Style="{DynamicResource GameDesk}" MouseEnter="Rectangle_MouseEnter" /> </Grid> </Window> ... which should use XAML resources from GameDesk.xaml which is in the main project and it seems that I can't use Pack URI (http://msdn.microsoft.com/en-us/library/aa970069.aspx). How can I specify the file? Should I use absolute path? (C:\Work...\Main\Resources\GameDesk.xaml) Or is there any other way? Thank you for help!

• Can I serialize an object if I didn't write the class used to instantiate that object?

  - by Richard77

  Hello, I've a simple class [Serializable] public class MyClass { public String FirstName { get; set: } public String LastName { get; set: } //Bellow is what I would like to do //But, it's not working //I get an exception ContactDataContext db = new ContactDataContext(); public void Save() { Contact contact = new Contact(); contact.FirstName = FirstName; contact.LastName = LastName; db.Contacts.InsertOnSubmit(contact); db.SubmitChanges(); } } I wanted to attach a Save method to the class so that I could call it on each object. When I introduced the above statement which contains ContactDataContext, I got the following error "In assembly ... PublicKeyToken=null' is not marked as serializable" It's clear that the DataContext class is generated by the framework (). I checked and did not see where that class was marked serialize. What can I do to overcome that? What's the rule when I'm not the author of a class? Just go ahead and mark the DataContext class as serializable, and pretend that everything will work? Thanks for helping

• asp.net ajax toolkit combobox doesn't work in hidden div

  - by sam

  I have a combobox inside a hidden div which I use css display = none to make it invisible, but when I make the div visible by setting display = block, the combobox just show the input and its button and ul list all have css as display = 'none', visibility ='hidden'. I can tell it is done by combobox inbuild javascript because I tried to use javascript to set the css manually with no luck. It is a bug of combobox. Urgent help needed. I spent a week to solve this, and our team put a lot trust on the toolkit. Please help me on this, all javascript gurus, thanks. Below is the code to reproduce the bug. When you run it, you can't see the dropdown: <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="WebApplication1._Default" %> <%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="asp" %> <asp:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server"> </asp:ToolkitScriptManager> <div id="d" style="display:none"> <asp:ComboBox ID="ComboBox1" runat="server"> <asp:ListItem>a</asp:ListItem> <asp:ListItem>d</asp:ListItem> <asp:ListItem>f</asp:ListItem> </asp:ComboBox> <asp:Label ID="Label1" runat="server" Text="Label"></asp:Label> </div> <div ID="Button1" runat="server" onclick="show();">click me</div> <script type="text/javascript"> function show() { var d = $get('d'); d.style.display = 'block'; } </script>

• Alternative to MS Project 2007 for production scheduling?

  - by john c

  OK... Im coming to grips with the fact that MS Project 2007 may not be the correct tool for my production scheduling. We serve 120 to 150 projects a year with durations from 6 weeks to 12 months. The task are simple (6 to 8 per project) and the resource pool is stable (15 to 20 people). It's really an assembly line product but with extremely varied durations. I need to be able to prioritize the projects for production and run projects concurrently to fully utilize my resources. What are the feelings of the stackoverflow community. Am I using the wrong program? I was really hoping to make this simple for non-programer types to input project data into a form and have the schedule software automated enough to make most of the decisions. Is there a better solution available commercially? I'd like to hold on writing a custom spreadsheet as a last resort but if that's the best route then so be it. Thank you so much for your input.
