Sorry if the title is unclear - not sure how to phrase it. Feel free to edit it. I have a web service written in C# and it uses an enum. When I am consuming this webservice with Flash, I had Flex generate the proxy classes - which also generates said enum in Actionscript. My problem is that I don't know how to use this generated Actions...
This code is taken from a SCJP practice test: 3. public class Bridge { 4. public enum Suits { 5. CLUBS(20), DIAMONDS(20), HEARTS(30), SPADES(30), 6. NOTRUMP(40) { public int getValue(int bid) { return ((bid-1)*30)+40; } }; 7. Suits(int points) { this.points = points; } 8. private i...
With GCC, I could do packing of enums using attribute((packed)), but it seems the closest thing in MSVC, #pragma pack, does not work on enums. Does anyone know of a way to pack enums into 1 byte instead of the usual integer size? ...
Hi I am using enums converted to a string with a switch but it doesn't work.

I've been trying to read a bit of the C++ standard to figure out how enum's work. There's actually more there than I originally thought. For a scoped enumeration, it's clear that the underlying type is int unless otherwise specified with an enum-base clause (it can be any integral type). enum class color { red, green, blue}; // these ...
I'm trying to create an Enum that has a string label and a value and I plan to use this to read stuff from an ini file. For example in the ini file I might have some double, int or string type values preceded by the tag/name of the value: SomeFloat = 0.5 SomeInteger = 5 FileName = ../Data/xor.csv When I read the tag from a file it co...

For people suggesting throwing an exception: Throwing an exception doesn't give me a compile-time error, it gives me a runtime error. I know I can throw an exception, I'd rather die during compilation than during runtime. First-off, I am using eclipse 3.4. I have a data model that has a mode property that is an Enum. enum Mode {on(......
I am trapping a KeyDown event and I need to be able to check whether the current keys pressed down are : Ctrl + Shift + M ? I know I need to use the e.KeyData from the KeyEventArgs, the Keys enum and something with Enum Flags and bits but I'm not sure on how to check for the combination. ...
From iPhone UIControl UIControlEventAllTouchEvents = 0x00000FFF, UIControlEventAllEditingEvents = 0x000F0000, UIControlEventApplicationReserved = 0x0F000000, UIControlEventSystemReserved = 0xF0000000, UIControlEventAllEvents = 0xFFFFFFFF Now I assume the UIControlEventApplication is the 'range' I can use to spe...
If you have a set of related words (e.g. Row & Column or On & Off), how do you find the collective word that describes those words? Specifically, how do you name an enum? If I have "Red", "Green" and "Blue", a sensible enum name might be "Color". Values of "On" and "Off" might have a sensible enum name of "Power". But how do I name t...
