  • business object and codelist

    - by feiroox
    Hi How to design a business object? I have a library which returns me an Object which have ten lists of other different objects. I need to store it into database all. List of objects are often like: class Item { private int id; private String name; private double point; } But the name is often the same. Like basic title of the product or code. Containing from 3 characters up to 70characters. Should I make conversion for every Object to: (or something similar) class ConvertedItem { private int id; private int code; private double point; } And have a separated table of codes ( I guess around 60). Or do not bother with duplicated stuff? It's not mission critical app. What would you do in my case? thanks in advance

  • Why is forwarding variadic parameters invalid?

    - by awesomeyi
    Consider the variadic function parameter: func foo(bar:Int...) -> () { } Here foo can accept multiple arguments, eg foo(5,4). I am curious about the type of Int... and its supported operations. For example, why is this invalid? func foo2(bar2:Int...) -> () { foo(bar2); } Gives a error: Could not find an overload for '_conversion' that accepts the supplied arguments Why is forwarding variadic parameters invalid? What is the "conversion" the compiler is complaining about?

  • Help with DateTime in format I need

    - by baron
    I am working with DateTime, trying to get date in the format like this: 03.05.2010-04.05.23 that is: dd.MM.yyyy-HH.mm.ss I'm using DateTime.ParseExact to try to achieve this (maybe wrong) So far I have: var dateInFormat = DateTime.ParseExact(DateTime.Now.ToShortDateString(), "dd.MM.yyyy.HH.mm.ss", null); But can't quite get exactly what I want. Basically I want to keep the 0, for example time is 05:03:20 PM I don't want it to show like 5:3:20 PM Any ideas?

  • How to store and compare time-zone sensitive times

    - by Chad Moran
    I have a data structure where an entity has times stored as an int (minutes into the day) for fast comparison. The entity also has a Foreign Key reference back to a TimeZone table which contains the .NET CLR ID Name and it's Standard Time/Daylight Time acronyms. Since this information is stored as time-zone insensitive - I was wondering how in LINQ to SQL I could convert this into a UTC DateTime for comparison against other times that will be in UTC. Just to be clear this conversion has to be done server-side so that I can execute filtering on the SQL Server and not the client. I am using .NET 3.5 SP1 and SQL Server 2008.

  • Converting Negative Decimal To String Loses the -

    - by coffeeaddict
    I'm required to send in a negative myDecimalValue.ToString("C"); The problem is if myDecimalValue is a negative, lets say -39, after conversion I'm getting $39.00 as the string not $39.00. So I'm not sure how to go about this. This is the utility method that takes in the decimal. If the decimal is negative, I want the ToString to show a negative public static BasicAmountType CreateBasicAmount(string amount, CurrencyCodeType currencyType) { BasicAmountType basicAmount = new BasicAmountType { currencyID = currencyType, Value = amount }; return basicAmount; } I could go either way, a C or F2, all I care is about getting that negative sign intothe string if the incoming decimal is negative. I suppose there's no way to do this unless I check for negativity inside my utility method here. I can't just send a negative number and expect the ToString to work and for the ToSTring to automatically see that the decimal is negative incoming?

  • Type or namespace name could not be found

    - by Pandiya Chendur
    I use this: public IQueryable<MaterialsView> FindAllMaterials() { var materials = from m in db.Materials join Mt in db.MeasurementTypes on m.MeasurementTypeId equals Mt.Id select new MaterialsView { MatId = m.Mat_Name, MesName = Mt.Name, MesType = m.Mat_Type }; return materials; } It gives me the following errors: The type or namespace name MaterialsView could not be found (are you missing a using directive or an assembly reference?) Cannot implicitly convert type System.Collections.Generic.IEnumerable<MaterialsView> to System.Linq.IQueryable<MaterialsView>. An explicit conversion exists (are you missing a cast?) The type arguments for method System.Linq.Enumerable.ToList<TSource>(System.Collections.Generic.IEnumerable<TSource>) cannot be inferred from the usage. Try specifying the type arguments explicitly. I have googled it and found this SO question but it doesn't help. What's wrong?

  • How to store enum values in a NSMutableArray

    - by Oysio
    My problem is since an enum in objective-c essentially is an int value, I am not able to store it in a NSMutableArray. Apparently NSMutableArray won't take any c-date types like an int. Is there any common way to achieve this ? typedef enum { green, blue, red } MyColors; NSMutableArray *list = [[NSMutableArray alloc] initWithObjects: green, blue, red, nil]; //Get enum value back out MyColors greenColor = [list objectAtIndex:0];

  • C++ - Opening a file inside a function using fopen

    - by Josh
    I am using Visual Studio 2005 (C++). I am passing a string into a function as a char array. I want to open the file passed in as a parameter and use it. I know my code works to an extent, because if I hardcode the filename as the first parameter it works perfectly. I do notice if I look at the value as a watch, the value includes the address aside the string literal. I have tried passing in the filename as a pointer, but it then complains about type conversion with __w64. As I said before it works fine with "filename.txt" in place of fileName. I am stumped. void read(char fileName[50],int destArray[MAX_R][MAX_C],int demSize[2]) { int rows=0; int cols=0; int row=0; int col=0; FILE * f = fopen(fileName,"r"); ...

  • How to insert a SQLite record with a datetime set to 'now' in Android application?

    - by droidguy
    Say, we have a table created as: create table notes (_id integer primary key autoincrement, created_date date) To insert a record, I'd use ContentValues initialValues = new ContentValues(); initialValues.put("date_created", ""); long rowId = mDb.insert(DATABASE_TABLE, null, initialValues); But how to set the date_created column to "now"? To make it clear, the initialValues.put("date_created", "datetime('now')"); Is not the right solution. It just sets the column to "datetime('now')" text.
