问题 I am trying to display data from an external .jsp file, which is set up something like this: <tag> <innertag1 id="1"> <innertag1 id="2"> </tag> <tag> <innertag2 id="3"> <innertag2 id="4"> </tag> To display only information from only one particular "innertag" tag, I'm currently using: NodeList labs = XMLInfo.getElementsByTagName("innertag1"); I'd like to be able to isolate any particular tag with ease. Theoretically, I could create many individual pages and simply change the values to

问题 From what I can see, SubSonic 2.x stored procedure parameter data types can only be of type System.Data.DbType. Is there a quick way to add System.Data.SqlDbType so we can use System.Data.SqlDbType.Structured to pass tables - ultimately to TVP's? In this particular project, all data caller functions are accessed through StoredProcedures.cs. If we switched to 3.x, does it support SqlDbType.Structured, and if so, is it a seamless integration to retain the current StoredProcedures.cs methods?

问题 I am asking this in response to this answer. I'm using an example of Variable and Var - edit Pls note I am asking where to use Var or Variable : Class NewClass { private String Variable = ""; Public Class (String Var) { NewClass.Var = Variable; } } OR private String Variable = ""; Public Class (String Variable) { NewClass.Variable = Var; // OR WHATEVER OTHER COMBINATIONS IT MAY BE. } } Which ones are the class variables, how does this differ from the parameters and which goes where? edit I

问题 I've been searching for this and it seems like it should be something simple, but apparently not so much. I want to return a resultSet within PostgreSQL 9.4.x using an array parameter so: | id | count | -------------- | 1 | 22 | -------------- | 2 | 14 | -------------- | 14 | 3 | where I'm submitting a parameter of {'1','2','14'} . Using something (clearly not) like: SELECT id, count(a.*) FROM tablename a WHERE a.id::int IN array('{1,2,14}'::int); I want to test it first of course, and then

问题 I have a record in VHDL that contains a pointer ( access ). I need to create a function that receives this record as parameter and from its data write in a file. But simulating with MODELSIM I get the following error: **Error: (vcom-1462) Illegal declaration of constant "xxx" of type x_file_format (type is or contains access type). How can I pass a pointer as parameter to a function? 回答1: Function parameters can only be constant (or signal or file) inputs. Access types must be variables.

问题 I've created a COM object using ATL. I want to create a new object that can be returned from a method, and passed in as a parameter. I've created the coclass, but I can't figure out how to add a method that will accept it as a parameter. The error I'm getting is MIDL2025: syntax error: expecting a type specification near "IgBrush". I'm using Visual Studio 2008. When I added an enumeration, I recall playing around with the IDL quite a bit, and eventually got it to accept the enumeration as a

问题 Any comments on this code pieces to make it more professional will be gladly accepted. This is why I opened this topic. But the main concern is this; I need to pass item ids, store ids, and start date and end date to get sale records. One of the problem is because of SQL parameter limit (2100), I cannot send more than 2100 parameters to the statement. Now I am trying to receive records store by store (store number is more than 4000 and also item amount). But I could not figure out a good way

问题 In a Controller, I'm trying to access a parameter which is deeply nested. Here is my parameter trace. Parameters: {"utf8"=>"✓", "authenticity_token"=>"2j+Nh5C7jPkNOsQnWoA0wtG/vWxLMpyKt6aiC2UmxgY=", "inventory"=>{"ingredients_attributes"=>{"0"=>{"ingredient_name"=>"Bread"}}, "purchase_date"=>"11", "purchase_price"=>"11", "quantity_bought"=>"11"}, "commit"=>"Create Inventory"} I'm trying to retrieve "Bread" from this. I tried params[:inventory][:ingredient][:ingredient_name] and other

问题 Assuming the following method, and I know it does not work: I want to create a new instance of a generic type public List<TPer> getDATA<TPer>(TPer per, int acao) where TDal: new() { //Is it possible create a new instance of a generic type inside the body of a generic method? TDal dal = new TDal(); //<-- I know it is NOT OK List<TPer> lst = new List<TPer>(); lst = dal.getDATA(per, acao); return lst; } I could write something like this: List<TPer> getDATA<TPer,TDal>(TPer per, int acao) where
