• Initialize generic object from a System.Type

  - by CaptnCraig

  I need to create a generic type, but I do not know the type at compile time. I would like to do this: Type t = typeof(whatever); var list = new List<t> this won't compile, because t is not a valid type. But it does know all about a valid type. Is there a way to dynamically create the generic list from a System.Type like this? I may need reflection, and that's ok, I am just a bit lost here.

• Nhibernate Complex Type binding

  - by user329983

  I have two oracle user defined types: Audit_Type – A normal object with two fields a string and a number Audit_Table_Type – A table of audit_types, (an array) I have a stored procedure that takes as a parameter an Audit_Table_Type. List<Audit_Type> table = new List<Audit_Type>(); var query = session.CreateSQLQuery("call Audit_Rows(Audit_Table_Type(:table))") .SetParameterList("table", table, NHibernateUtil.Custom(typeof(AuditTypeUDT))) This is what I did intuativly created the ICompositeType and just set in a list of them in but this gives me nothing close to what I wanted. I couldn’t figure out how to bind to a table at all. I have built the inline sql that would do this for me but it would destroy my shared pool (not using binds). So a General question how do I bind to complex/composite types using Nhibernate?

• Disambiguating Named Entities in Java

  - by Alterscape

  I have a list of strings (company names, in this case), and a Java program that extracts a list of things that look like company names out of mostly-unstructured text. I need to match each element of extracted text to a string in the list. Caveat: the unstructured text has typos, things like "Blah, Inc." referred to as "Blah," etc. I've tried Levenshtein Edit Distance, but that fails for predictable reasons. Are there known best-practices ways of tackling this problem? Or am I back to manual data-entry?

• How to build up a lookup table in microcontroller?

  - by GiGi

  Hi, I am so confused about how to build up a 3-dimension lookup table. Is the template as follows: create a 3 dimensional array to store data. Then create linked list. Then create function 'insert' to put all the data into the array? As some book said, linked list should be static const, is it need to create another function to expand the list? Because the lookup table should be used in a microcontroller, it only needs to finish the operation of putting the data into the array and whenever want to find the data, it will be fast and easy to search. Could you help me with that and give me some suggestions? Thank you.

• python destructuring-bind dictionary contents

  - by Stephen

  Hi, I am trying to 'destructure' a dictionary and associate values with variables names after its keys. Something like params = {'a':1,'b':2} a,b = params.values() but since dictionaries are not ordered, there is no guarantee that params.values() will return values in the order of (a,b). Is there a nice way to do this? Thanks

• Filtering subsets using Linq

  - by Nathan Matthews

  Hi All, Imagine a have a very long enunumeration, too big to reasonably convert to a list. Imagine also that I want to remove duplicates from the list. Lastly imagine that I know that only a small subset of the initial enumeration could possibly contain duplicates. The last point makes the problem practical. Basically I want to filter out the list based on some predicate and only call Distinct() on that subset, but also recombine with the enumeration where the predicate returned false. Can anyone think of a good idiomatic Linq way of doing this? I suppose the question boils down to the following: With Linq how can you perform selective processing on a predicated enumeration and recombine the result stream with the rejected cases from the predicate?

• Adding a child node to a JSON node dynamically

  - by Sai

  I have to create a nested multi level json depending on the resultset that I get from MYSQL. I created a json object initially. Now I want to add child nodes to the already child nodes in the object. d = collections.OrderedDict() jsonobj = {"test": dict(updated_at="today", ID="ID", ads=[])} for rows1 in rs: jsonobj['list']["ads"].append(dict(unit = "1", type ="ad_type", id ="123", updated_at="today", x_id="111", x_name="test")) cur.execute("SELECT * from f_test") rs1 = cur.fetchall() for rows2 in rs1: propertiesObj = [] d["name"]="propName" d["type"]="TypeName" d["value"]="Value1" propertiesObj.append(d) jsonobj['play_list']["ads"].append() Here in the above line I want to add another child node to [play_list].[ads] which is a array list again. the output should look like the following [list].[ads].[preferences].

So... is there anyway for me to make my life easier? Thanks in advance.

• WPF Binding not updating when binded object is updated

  - by Chris Klepeis

  I'm trying to bind to a custom control like so: <my:GanttChartTaskListView Name="ganttChartTaskListView1" ItemsSource="{Binding Source={x:Static local:TaskCollection.taskList}}" /> In my WPF Window constructor I add add an item to my taskList, when it loads I can see that item in my custom control, however, when I subsequently add items it does not update. I tried setting Mode=TwoWay, however, then it says the "Path" is required and I'm not familiar with binding like that (this is new to me). Here is my TaskCollection class: namespace ProjectManager { public static class TaskCollection { private static List<TaskItem> _taskList = new List<TaskItem>(); public static List<TaskItem> taskList { get {return _taskList; } set { _taskList = value; } } } } Any ideas? Is there a better / easier way to do this?

• Extension method question. Why do I need to use someObj = someObj.somemethod();

  - by Kettenbach

  Hi All, I have a simple extension method that I would like to use to add an item to an array of items. public static T[] addElement<T>(this T[] array, T elementToAdd) { var list = new List<T>(array) {elementToAdd}; return list.ToArray(); } this works ok, but when I use it, I am having to set the array equal to the return value. I see that I am returning an Array. I likely want this method to be void, but I would like the item added. Does anyone have any ideas on what I need to do , to make this work the way I am wanting? Instead of someArray = someArray.addElement(item), I just want to do someArray.addElement(item) and then someArray be ready to go. What am I missing here? Thanks, ~ck in San Diego

• Check keyword popularity of 2000 phrases?

  - by Mark

  I just found a list of about 2000 car manufacturers which I want to put into a drop-down list... but 2000 is probably a bit too many, so I want to filter it down to maybe the top 100 most popular cars. I figure I can just use Google search popularity to give me a rough estimate of how popular the car is... but I can't find a tool that will let me query 2000 keywords. Anyone know of one?

• Retrieving selected data from DataGrid with IEnumerable<IDictionary> (Silverlight)

  - by RemiX

  I have an application that can dynamically load data into a DataGrid. What's needed is an object of IEnumerable<IDictionary>, and a List<Dictionary<string,object>> is supplied (each Dictionary in the list has exactly the same keys). The data is loaded into the DataGrid and shown, but now I want to retrieve the data the user has clicked on. Using datagrid.SelectedItem, Silverlight complains it cannot evaluate the variable, not even when type-casted. I tried keeping the List<Dictionary<string,object>> and retrieving the right data from it using datagrid.SelectedIndex, but this index changes when the DataGrid is sorted. Does anyone know a solution to this problem?

• Setting selected item on Listbox in Silverlight - Windows Phone 7

  - by Fishcake

  I have a databound Listbox bound to a generic list as follows (Provider is a very simple class that just includes a single property (Name). ProviderList = new List<Provider>(); //Populate list Providers.ItemsSource = ProviderList; I can save the selected item with no problem but I can't manage to set the selected item from code afterwards. I am trying to do so as follows: int x = Providers.Items.IndexOf((Provider)_Settings["provider"]); However IndexOf() is always returning -1. If I inspect both Providers.Items[1] and _Setting["provider"] at runtime using the immediate window they both return {StoreRetrieveData.Provider} Name: "Greenflag" Am I doing something wrong (well clearly I am)?

• Passing variable string to create arrays (Android)

  - by dweebsonduty

  Hello all, I am a newb to Android and Java and want to write a funtion that will display a list based on a varable that I pass to the function. The function is below and the code below creates an array out of a string called type, but what I want to do is pass it a variable string and have it build a list based on that string. So if I wanted the type list I would say list_it("type") But if I try something like getResources().getStringArray(R.array.thelist); it doesn't work. Can someone point me in the right direction? public void list_it(String thelist){ String[] types = getResources().getStringArray(R.array.type); ArrayAdapter<String> mAdapter = new ArrayAdapter<String>(this, R.layout.list_item1, types); setListAdapter(mAdapter); ListView lv = getListView(); lv.setTextFilterEnabled(true); }
