  • C# working with decorated members

    - by Ronnie Overby
    Take this class for example: public class Applicant : UniClass<Applicant> { [Key] public int Id { get; set; } [Field("X.838.APP.SSN")] public string SSN { get; set; } [Field("APP.SORT.LAST.NAME")] public string FirstName { get; set; } [Field("APP.SORT.FIRST.NAME")] public string LastName { get; set; } [Field("X.838.APP.MOST.RECENT.APPL")] public int MostRecentApplicationId { get; set; } } How would I go about getting all of the properties that are decorated with the field attribute, get their types, and then assign a value to them?

  • Setting property default values for a Web User Control

    - by Jeremy Holland
    I am trying to build a web user control and set some default values for its properties in the code-behind like this: [DefaultValue(typeof(int), "50")] public int Height { get; set; } [DefaultValue(typeof(string), "string.Empty")] public string FamilyName { get; set; } [DefaultValue(typeof(Color), "Orange")] public System.Drawing.Color ForeColor { get; set; } When I add the user control to the page and call it without any properties: <uc1:Usercontrol ID="uc" runat="server" /> the default values are not set and every property is 0 or null. What am I doing wrong? Thanks.

  • Best way to get record counts grouped by month, adjusted for time zone, using SQL or LINQ to SQL

    - by Jeff Putz
    I'm looking for the most efficient way to suck out a series of monthly counts of records in my database, but adjusting for time zone, since the times are actually stored as UTC. I would like my result set to be a series of objects that include month, year and count. I have LINQ to SQL objects that looks something like this: public class MyRecord { public int ID { get; set; } public DateTime TimeStamp { get; set; } public string Data { get; set; } } I'm not opposed to using straight SQL, but LINQ to SQL would at least keep the code a lot more clean. The time zone adjustment is available as an integer (-5, for example). Again, the result set what I'm looking for is objects containing the month, year and count, all integers. Any suggestions? I can think of several ways to do it straight, but not with a time zone adjustment.

  • Can I Automap a tree hierarchy with Fluent NHibernate?

    - by NakChak
    Is it possible to auto map a simple nested object structure? Something like this: public class Employee : Entity { public Employee() { this.Manages = new List<Employee>(); } public virtual string FirstName { get; set; } public virtual string LastName { get; set; } public virtual bool IsLineManager { get; set; } public virtual Employee Manager { get; set; } public virtual IList<Employee> Manages { get; set; } } It causes the following error at run time: Repeated column in mapping for collection: SharpKtulu.Core.Employee.Manages column: EmployeeFk Is it possible to automap this sort of structure, or do I have override the auto mapper for this sort of structure?

  • Entity Framework 4.1 (Code First) audit column

    - by Ken Pespisa
    I'm using Entity Framework 4.1 with a Code-First approach on an ASP.NET MVC site Say I have an entity named Profile that keeps track of a user's favorite book, and I want to track when the user updates their favorite book. UPDATED: Using the class below as an example, I want to set the FavoriteBookLastUpdated property to the current date whenever the value of the FavoriteBook property changes. public class Profile { public int Id { get; set; } public string Name { get; set; } public string FavoriteBook { get; set; } public DateTime? FavoriteBookLastUpdated { get; set; } } Right now I just update that field, if appropriate, in the controller's Edit action before calling the DBContext's SaveChanges() method. Is there a way I can put that logic in my model somehow? I'd prefer not to use triggers on the database side.

  • Entity Framework 4 code-only reference column name

    - by Victor
    I created classes: public class Country { public long CountryId {get;set;} public string CountryName {get;set;} } public class Profile { public long ProfileId {get;set;} public string ProfileName {get;set;} public Country Country {get;set;} } and configuration for Profile: public class ProfileConfiguration : EntityConfiguration<Profile> { public IlluminatiCoreProfileConfiguration() { Relation(p => p.Country); } } Then I create context and run context.CreateDatabase(). New database contains table Profiles with column Country_CountryId. How can I write configuration for changing column name to "CountryId"? Thanks.

  • Adding objects to LDAP via CGI

    - by musashiXXX
    I have a web form that collects information and submits it to a cgi that attempts to insert the data into LDAP. The problem is that I'm trying to use a variable with ::ldap::add and it's just not working. Here's the code: if {[string length env(QUERY_STRING)] != 0} { set handle [::ldap::connect localhost] set dn "cn=admin,dc=mycompany,dc=com" set pw "myPassword" ::ldap::bind $handle $dn $pw set dn "cn=[ncgi::value givenName] [ncgi::value sn],ou=people,dc=mycompany,dc=com" set formValues [ puts "cn {{[ncgi::value givenName] [ncgi::value sn]}}" puts "displayName [ncgi::value givenName] [ncgi::value sn]" foreach {key value} [ncgi::nvlist] { if {[string length $value] != 0} { puts "$key $value" } } puts "objectClass top" puts "objectClass person" puts "objectClass organizationalPerson" puts "objectClass inetOrgPerson" ] ::ldap::add $handle $dn { $formValues } ldap::unbind $handle } However, if I replace $formValues with the actual entries that I want to insert into LDAP, they get added just fine. I'm new to TCL so I wouldn't be surprised if there were some glaring errors in this snippet. Thanks in advance!

  • ASP Classic Named Parameter in Paramaterized Query: Must declare the scalar variable

    - by My Alter Ego
    I'm trying to write a parameterized query in ASP Classic, and it's starting to feel like i'm beating my head against a wall. I'm getting the following error: Must declare the scalar variable "@something". I would swear that is what the hello line does, but maybe i'm missing something... <% OPTION EXPLICIT %> <!-- #include file="../common/adovbs.inc" --> <% Response.Buffer=false dim conn,connectionString,cmd,sql,rs,parm connectionString = "Provider=SQLOLEDB.1;Integrated Security=SSPI;Data Source=.\sqlexpress;Initial Catalog=stuff" set conn = server.CreateObject("adodb.connection") conn.Open(connectionString) set cmd = server.CreateObject("adodb.command") set cmd.ActiveConnection = conn cmd.CommandType = adCmdText cmd.CommandText = "select @something" cmd.NamedParameters = true cmd.Prepared = true set parm = cmd.CreateParameter("@something",advarchar,adParamInput,255,"Hello") call cmd.Parameters.append(parm) set rs = cmd.Execute if not rs.eof then Response.Write rs(0) end if %>

  • Deserialize array values to .NET properties using DataContractJsonSerializer

    - by James Cadd
    I'm working with the DataContractJsonSerializer in Silverlight 4 and would like to deserialize the following JSON: { "collectionname":"Books", "collectionitems": [ ["12345-67890",201, "Book One"], ["09876-54321",45, "Book Two"] ] } Into classes like the following: class BookCollection { public string collectionname { get; set; } public List<Book> collectionitems { get; set; } } class Book { public string Id { get; set; } public int NumberOfPages { get; set; } public string Title { get; set; } } What's the proper place to extend DataContractJsonSerializer to map the unnamed first array element in "collectionitems" to the Id property of the Book class, the second element to the NumberOfPages property and the final element to Title? I don't have control over the JSON generation in this instance and would like the solution to work with the Silverlight subset of .NET. It would be great if the solution could perform the reverse for serialization as well.

  • T-SQL: How to make a positive value turn into the equivalent negative value (e.g "10.00" to "-10.00"

    - by RPM1984
    Ok so i have a DECIMAL field called "Score". (e.g 10.00) Now, in my SP, i want to increment/decrement the value of this field in update transactions. So i might want to do this: SET @NewScore = @CurrentScore + @Points Where @Points is the value im going to increment/decrement. Now lets say @Points = 10.00. In a certain scenario, i want 10.00 to become -10.00 So the statement would be translated to: SET @NewScore = @CurrentScore + -10.00 How can i do that? I know its a strange question, but basically i want that statement to be dynamic, in that i dont want to have a different statement for incrementing/decrementing the value. I just want something like this: SET @Points = 10.00 IF @ActivityBeingPerformedIsFoo BEGIN -- SET @Points to be equivalent negative value, (e.g -10.00) END SET @NewScore = @CurrentScore + @Points

  • How to lowercase every element of a collection efficiently?

    - by Chris
    Whats the most efficient way to lower case every element of a list or set? My idea for a List: final List<String> strings = new ArrayList<String>(); strings.add("HELLO"); strings.add("WORLD"); for(int i=0,l=strings.size();i<l;++i) { strings.add(strings.remove(0).toLowerCase()); } is there a better, faster way? How would this exmaple look like for a set? As there is currently no method for applying an operation to each element of a set (or list) can it be done without creating an additional temporary set? Something like this would be nice: Set<String> strings = new HashSet<String>(); strings.apply( function (element) { this.replace(element, element.toLowerCase();) } ); Thanks,

  • Data Source Security Part 1

    - by Steve Felts
    I’ve written a couple of articles on how to store data source security credentials using the Oracle wallet.  I plan to write a few articles on the various types of security available to WebLogic Server (WLS) data sources.  There are more options than you might think! There have been several enhancements in this area in WLS 10.3.6.  There are a couple of more enhancements planned for release WLS 12.1.2 that I will include here for completeness.  This isn’t intended as a teaser.  If you call your Oracle support person, you can get them now as minor patches to WLS 10.3.6.   The current security documentation is scattered in a few places, has a few incorrect statements, and is missing a few topics.  It also seems that the knowledge of how to apply some of these features isn’t written down.  The goal of these articles is to talk about WLS data source security in a unified way and to introduce some approaches to using the available features.  Introduction to WebLogic Data Source Security Options By default, you define a single database user and password for a data source.  You can store it in the data source descriptor or make use of the Oracle wallet.  This is a very simple and efficient approach to security.  All of the connections in the connection pool are owned by this user and there is no special processing when a connection is given out.  That is, it’s a homogeneous connection pool and any request can get any connection from a security perspective (there are other aspects like affinity).  Regardless of the end user of the application, all connections in the pool use the same security credentials to access the DBMS.   No additional information is needed when you get a connection because it’s all available from the data source descriptor (or wallet). java.sql.Connection conn =  mydatasource.getConnection(); Note: You can enter the password as a name-value pair in the Properties field (this not permitted for production environments) or you can enter it in the Password field of the data source descriptor. The value in the Password field overrides any password value defined in the Properties passed to the JDBC Driver when creating physical database connections. It is recommended that you use the Password attribute in place of the password property in the properties string because the Password value is encrypted in the configuration file (stored as the password-encrypted attribute in the jdbc-driver-params tag in the module file) and is hidden in the administration console.  The Properties and Password fields are located on the administration console Data Source creation wizard or Data Source Configuration tab. The JDBC API can also be used to programmatically specify a database user name and password as in the following.  java.sql.Connection conn = mydatasource.getConnection(“user”, “password”); According to the JDBC specification, it’s supposed to take a database user and associated password but different vendors implement this differently.  WLS, by default, treats this as an application server user and password.  The pair is authenticated to see if it’s a valid user and that user is used for WLS security permission checks.  By default, the user is then mapped to a database user and password using the data source credential mapper, so this API sort of follows the specification but database credentials are one-step removed from the application code.  More details and the rationale are described later. While the default approach is simple, it does mean that only one database user is doing all of the work.  You can’t figure out who actually did the update and you can’t restrict SQL operations by who is running the operation, at least at the database level.   Any type of per-user logic will need to be in the application code instead of having the database do it.  There are various WLS data source features that can be configured to provide some per-user information about the operations to the database. WebLogic Data Source Security Options This table describes the features available for WebLogic data sources to configure database security credentials and a brief description.  It also captures information about the compatibility of these features with one another. Feature Description Can be used with Can’t be used with User authentication (default) Default getConnection(user, password) behavior – validate the input and use the user/password in the descriptor. Set client identifier Proxy Session, Identity pooling, Use database credentials Use database credentials Instead of using the credential mapper, use the supplied user and password directly. Set client identifier, Proxy session, Identity pooling User authentication, Multi Data Source Set Client Identifier Set a client identifier property associated with the connection (Oracle and DB2 only). Everything Proxy Session Set a light-weight proxy user associated with the connection (Oracle-only). Set client identifier, Use database credentials Identity pooling, User authentication Identity pooling Heterogeneous pool of connections owned by specified users. Set client identifier, Use database credentials Proxy session, User authentication, Labeling, Multi-datasource, Active GridLink Note that all of these features are available with both XA and non-XA drivers. Currently, the Proxy Session and Use Database Credentials options are on the Oracle tab of the Data Source Configuration tab of the administration console (even though the Use Database Credentials feature is not just for Oracle databases – oops).  The rest of the features are on the Identity tab of the Data Source Configuration tab in the administration console (plan on seeing them all in one place in the future). The subsequent articles will describe these features in more detail.  Keep referring back to this table to see the big picture.

  • Calculating percentiles in Excel with "buckets" data instead of the data list itself

    - by G B
    I have a bunch of data in Excel that I need to get certain percentile information from. The problem is that instead of having the data set made up of each value, I instead have info on the number of or "bucket" data. For example, imagine that my actual data set looks like this: 1,1,2,2,2,2,3,3,4,4,4 The data set that I have is this: Value No. of occurrences 1 2 2 4 3 2 4 3 Is there an easy way for me to calculate percentile information (as well as the median) without having to explode the summary data out to full data set? (Once I did that, I know that I could just use the Percentile(A1:A5, p) function) This is important because my data set is very large. If I exploded the data out, I would have hundreds of thousands of rows and I would have to do it for a couple of hundred data sets. Help!

  • Setting Focus with ASP.NET AJAX Control Toolkit

    - by Jonathan S.
    I'm using the AutoComplete control from the ASP.NET AJAX Control Toolkit and I'm experiencing an issue where the AutoComplete does not populate when I set the focus to the assigned textbox. I've tried setting the focus in the Page_Load, Page_PreRender, and Page_Init events and the focus is set properly but the AutoComplete does not work. If I don't set the focus, everything works fine but I'd like to set it so the users don't have that extra click. Is there a special place I need to set the focus or something else I need to do to make this work? Thanks.
