I have a table DEAL and a table DEAL_TYPE. I would like to map this code:
public class Deal {
DealType type;
}
public enum DealType {
BASE("Base"), EXTRA("Extra");
}
The problem is that the data already exist in the database. And I'm having a hard time mapping the classes to the database.
The database looks something like that...

I have a WCF service operation that accepts a data contract parameter of custom type MyQuery -- function Search(q as MyQuery). The MyQuery object contains 2 properties:
MyQuery.SearchPhrase (string)

I also have a Flex client application that consumes this service. But when Flex invokes ...
I am trying to use a set of conditional statements that will set up an enumeration attributed with [Flags]. However, the compiler complains that 'm' is unassigned. How can I rewrite the following to achieve my intended functionality?
Media m;
if (filterOptions.ShowAudioFiles)
m = m | Media.Audio;
if (filterOptions.ShowDocumentFiles)...
If I have something like the following in a header file:
enum Foo
{
BAR,
BAZ
};
how do I declare a function that returns an enum of type foo? Can I just do something like the following:
Foo testFunc()
{
return Foo.BAR;
}
Or do I need to use typedefs or pointers or something?

I'm creating a program where the user has the option of creating their own custom properties that will ultimately be displayed in a PropertyGrid. Right now I don't want to mess with custom editors, so I'm only allowing primitive type properties (string, int, double, datetime, bool etc.) that the PropertyGrid already has built in editors ...
I've seen several questions/discussions here about the best way to handle and persist enum-like values (e.g. http://stackoverflow.com/questions/492096/persisting-data-suited-for-enums , http://stackoverflow.com/questions/256978/how-to-persist-an-enum-using-nhibernate ), and I'd like to ask what the general consenus is.

Hey All,
I have decided it is impossible to do the following (equivalent) enum operations via reflection - as the Enum class has no operators, and nor does the emitted code expose any operators:
object boxedEnum = MyEnum.Flag1 | MyEnum.Flag2;
boxedEnum &= ~MyEnum.Flag2; // Remove the flag.
So I am currently doing the following (equiv...
What is the quickest way to determine which members of an enum are not being used?

I have an enum in a low level namespace. I'd like to provide a class or enum in a mid level namespace that "inherits" the low level enum.
namespace low
{
public enum base
{
x, y, z
}
}
namespace mid
{
public enum consume : low.base
{
}
}
I'm hoping that this is possible, or perhaps some kind of class that can ...
Hey all,
I'm currently writing a helper function in VB.NET to convert an array of enum values to a CSV, but I'm encounting a few difficulties....
I'm not sure what type of arguement my function should take if I want to make it generic enough to handle any enum I pass into it.
This is what I've got so far:

Say my database tables have columns like UserType, SalesType, etc.
Should I have database tables with UserTypeID, userTypeName or should I just create a C# enumeration?

Part 1
In C, is there any difference between declaring an enum like this:
typedef enum{VAL1, VAL2,} firstEnum;
and like this:
enum secondEnum{Val1, Val2,};
Apart from the fact that when using secondEnum, you have to write:
enum secondEnum...;
Part 2
Also, am I right in thinking that the following is equivalent:
enum{Val1, Val...
Is the last comma required in a C enum declaration?
i.e. is the comma after VAL3 required?
enum{Val1, Val2, Val3,} someEnum;
Are there any side-effects of leaving it in/out
Thanks

In the post Enum ToString, a method is described to use the custom attribute DescriptionAttribute like this:
Enum HowNice {
[Description("Really Nice")]
ReallyNice,
[Description("Kinda Nice")]
SortOfNice,
[Description("Not Nice At All")]
NotNice
}
And then, you call a function GetDescription, using syntax like:

Hi,
I have the following Enum:
Public Enum myEnum As Integer
first = &H1
second = &H2
third = &H4
fourth = &H8
fifth = &H10
sixth = &H20
End Enum
It is neccessary, unfortunately, that the enum elements have those values, or at least have values that can be binary compared.
I have a class which can be set d...

}
If this Person class has to be persisted in a single table, how should...
If I bind a WinForms ComboBox to an enum type's values, i.e.
combo1.DropDownStyle = ComboBoxStyle.DropDownList;
combo1.DataSource = Enum.GetValues(typeof(myEnumType));
Who knows how I could achieve the same result, while, in addition to entries matching each enum value, I can also have a blank entry representing no selection?
I canno...
I was asked by a fellow developer if I could code in some enums into SubSonic as he was needing them and he pointed out a post on the old SubSonic forums.
If anyone is interested in this functionality then an issue has been opened at http://code.google.com/p/subsonicproject/issues/detail?id=81 if you'd like to place some comments and fe...
