  • C#. How to terminate a thread which has spawned another thread which is sleeping?

    - by Bobb
    I have a long running thread made from Thread.Start(). It spawns a background thread using QueueUserWorkItem which sleeps most of the time. Then the class-owner get disposed I call thread1.Join() but naturally it doesnt return because its child background thread is sleeping. What would be the right solution to gracefully terminate a thread which has other threads with little hassle? Thanks

  • rawurlencode() and urlencode() not working in CodeIgniter

    - by Keith Chason
    I am trying to encode a string into a safe url for generic purposes, and neither rawurlencode() nor urlencode() work when using CodeIgniter. I have used them and they work pefectly fine with straight PHP, but for whatever reason, it doesn't work. I haven't been able to find any others with this problem and thus no solution. Code: <a href="/search/degree/<?=rawurlencode($row->degree)?>" class="element_link"><?=$row->degree?></a>

  • Need a good way to store data in a DB from a table on a webpage that can have N columns.

    - by Abe Miessler
    Users need to be able to add a specific type of column to an otherwise static table on my web page and then save the information they enter in there to the database. I've been told that in reality they will almost never go over 5 columns but I would rather support N. The columns will all be of the same datatype. My first thought was to have an XML column with the values from all added columns in there but I was curious if anyone else had come up with a better solution. Suggestions?

  • $_SERVER["SCRIPT_URI"] not working? alternative?

    - by Ahmad Fouad
    Hi, This is odd, but for some reason the $_SERVER["SCRIPT_URI"] will not return the domain name when I am in child/sub-pages but will only work on the main page. Not sure if its due to the script (WordPress) or host, but please can you suggest any reliable solution to retrieve the domain name with PHP? I am very thankful in advance, Regards

  • Across process marhalling problem with an array of points

    - by ElMagn
    Hi All, We have what we think is a marshalling problem with a renderer object when called across process boundaries. The renderer is an ATL COM server with a COM object that implements the IPoints interface defined below: typedef [uuid(B0E01719-005A-427c-B9DD-B42A18E969AE)] struct Point { double X; double Y; } Point; [ object, uuid(3BFECFE3-B4FB-4f14-8257-6E065D02E3B3), helpstring("IPoints Interface"), dual, ] interface IPoints : IDispatch { HRESULT DrawPolyLine([in] long hDC, [in] short count, [in, size_is(count)] Point * points ); // many more like DrawLine } The count parameter represents the number of points and the points parameter represents an array of the actual points. We have two process running, a graphical display process (GDP) and a tabular (grid) display process (TDP). A factory in the GDP, written in C#, creates the renderer and the clients of the renderer in the GDP. When the clients call into the renderer, everything displays correctly. The renderer is created at start up BTW. There is another factory in the TDP, written in VB6, that calls into the factory in the GDP to create the clients. When the clients call into the renderer, only the first point in the array is marshaled correctly, all the other points are garbage. Seems that the rendering works only when the client creation is started from the same process as the renderer. Now, i am not sure what the solution to this problem is. It seems that if we can guarantee that the clients are always created from a thread in the same GDP process as the renderer then the points are marshaled correctly. We tried using a background thread from the Thread Pool in C# and it indeed worked. The problem is that Windows Forms created from the clients stopped working because accessing the form's controls from a thread other than the thread that created the control is not allowed. We might change the calls to access the forms but we have quite a few of them and are trying to look into a different solution that might involve making changes to the renderer. The other problem is that the renderer is legacy code and we can't just change the interface. I am wondering what can we do to the renderer's interface that would help with marshalling from across process calls. Any ideas would be greatly appreciated. Regards, ElMagn

  • How to build and deploy Python web applications

    - by sverrejoh
    I have a Python web application consisting of several Python packages. What is the best way of building and deploying this to the servers? Currently I'm deploying the packages with Capistrano, installing the packages into a virtualenv with bash, and configuring the servers with puppet, but I would like to go for a more Python based solution. I've been looking a bit into zc.buildout, but it's not clear for me what I can/should use it for.

  • What is the most effective way to create BigInteger instance from int value?

    - by Roman
    I have a method (in 3rd-party library) with BigInteger parameter: public void setValue (BigInteger value) { ... } I don't need 'all its power', I only need to work with integers. So, how can I pass integers to this method? My solution is to get string value from int value and then create BigInteger from string: int i = 123; setValue (new BigInteger ("" + i)); Are there any other (recommended) ways to do that?

  • How do I create/use a Fluent NHibernate convention to automap UInt32 properties to an SQL Server 200

    - by dommer
    I'm trying to use a convention to map UInt32 properties to a SQL Server 2008 database. I don't seem to be able to create a solution based on existing web sources, due to updates in the way Fluent NHibernate works - i.e. examples are out of date. I'm trying to have NHibernate generate the schema (via ExposeConfiguration). I'm happy to have NHibernate map it to anything sensible (e.g. bigint). Here's my code as it currently stands (which, when I try to expose the schema, fails due to SQL Server not supporting UInt32). Apologies for the code being a little long, but I'm not 100% sure what is relevant to the problem, so I'm erring on the side of caution. Most of it is based on this post. The error reported is: System.ArgumentException : Dialect does not support DbType.UInt32 I think I'll need a relatively comprehensive example, as I don't seem to be able to pull the pieces together into a working solution, at present. FluentConfiguration configuration = Fluently.Configure() .Database(MsSqlConfiguration.MsSql2008 .ConnectionString(connectionString)) .Mappings(mapping => mapping.AutoMappings.Add( AutoMap.AssemblyOf<Product>() .Conventions.Add<UInt32UserTypeConvention>())); configuration.ExposeConfiguration(x => new SchemaExport(x).Create(false, true)); namespace NHibernateTest { public class UInt32UserTypeConvention : UserTypeConvention<UInt32UserType> { // Empty. } } namespace NHibernateTest { public class UInt32UserType : IUserType { // Public properties. public bool IsMutable { get { return false; } } public Type ReturnedType { get { return typeof(UInt32); } } public SqlType[] SqlTypes { get { return new SqlType[] { SqlTypeFactory.Int32 }; } } // Public methods. public object Assemble(object cached, object owner) { return cached; } public object DeepCopy(object value) { return value; } public object Disassemble(object value) { return value; } public new bool Equals(object x, object y) { return (x != null && x.Equals(y)); } public int GetHashCode(object x) { return x.GetHashCode(); } public object NullSafeGet(IDataReader rs, string[] names, object owner) { int? i = (int?)NHibernateUtil.Int32.NullSafeGet(rs, names[0]); return (UInt32?)i; } public void NullSafeSet(IDbCommand cmd, object value, int index) { UInt32? u = (UInt32?)value; int? i = (Int32?)u; NHibernateUtil.Int32.NullSafeSet(cmd, i, index); } public object Replace(object original, object target, object owner) { return original; } } }

  • Controlling Solr score/sort

    - by Znarkus
    I want to filter a property within a range, but items that does not have the property should come last in the result. My solution was to set it to -1 if the property was not set. +(property:[10000000001 TO 10000000019] property:"-1"^0.5) This doesn't work, since every document with property:-1 get a very high score, for some reason. Is there a way to reliably control the sorting here? Boosting the range instead would mean I must boost every other term, which I'd rather not do.

  • avoid textarea rows/cols error?

    - by acidzombie24
    I am using a few page validation tools one problem i have is they tell me textarea must have rows and cols attribute. If i am setting this in CSS or using display:none (and using it to hold raw text data) can i do something to skip? it seems like the only answer is rows="0" cols="0" each time i use it. But i have a feeling that is not a good solution.

  • Optimizing a memoization decorator not increase call stack

    - by Tyler Crompton
    I have a very, very basic memoization decorator that I need to optimize below: def memoize(function): memos = {} def wrapper(*args): try: return memos[args] except KeyError: pass result = function(*args) memos[args] = result return result return wrapper The goal is to make this so that it doesn't add on to the call stack. It actually doubles it right now. I realize that I can embed this on a function by function basis, but that is not desired as I would like a global solution for memoizing. Any ideas?
