View 2 RepliesI have a URL lets say . some time i need to send HTTP and some time i need to send it to HTTPS for that i created a enum:
Private _protocol As Protocol
Enum Protocol
HTTP
HTTPS
[CODE]...
Now when i get value back from protocoltype it returns me integer value as enum do so tell me how to get string from enum or other substitute.
Dim targetUri As String = setting.protocolType & "://www.mysite.com"
RE - FilesystemRights Enum
This Code:
Dim FSRS As Type = GetType(FileSystemRights)
For Each fsr As String In [Enum].GetNames(FSRS)
TextBox1.AppendText(fsr.ToString & vbCrLf)
Next
Is there a way to get an enum to explicitly cast to it's base type?If I have something like this:
Code:
Public Enum Packets As Byte
Stuff = &H0
End Enum
I have to do
Code:
Dim test As Byte = CByte(Packets.Stuff)
Rather than
Code:
Dim test As Byte = Packets.Stuff
I don't see why that's the way it works, since you know that the enum will always have values of the base type.
In this post Jon Skeet pointed out that the following code should be changed to conform with the .NET naming conventions. Doing that would also decrease the amount of noise in the code.

I must admit, I was pretty much like a sheep and was following what others have done before me. I thought the prefix did not look right and then to have it twice did not make sense either. After looking at a couple of .NET Framework examples, it looks like this would be closer to the standard.

I don't know how to convert the following line from VB to C#:
Dim values As New List(Of T)(System.Enum.GetValues(GetType(T)))
My version doesn't work:
List<T> values = new List<T>(System.Enum.GetValues(typeof(T)));
The best overloaded method match for 'System.Collections.Generic.List.List(System.Collections.Generic.IEnumerable)'
has some invalid arguments
The constructor-parameter doesn't take it that way - what cast (or else) am I missing?
For clarification: It is wrapped up within the following generic method
public static void BindToEnum<T>()
{
List<T> values = new List<T>(System.Enum.GetValues(typeof(T)));
//...
}
I have the following code which obtains the compass direction from a degree value. I'm new to VB.Net and was wondering what is the best way to store the values, in an Enum or an Array?
[Code]...
In VS2008, you could write, for instance,
dim enumValue as MyEnum
enumValue =
And then as soon as you typed the =, you'd get a list of possible values of MyEnum. With VS2010, you have to type
dim enumValue as MyEnum
enumValue = MyEnum.
Before getting the list on typing the final. This makes for a lot more typing and seems to be a retrograde step ... is there an option I'm missing? (I have 'Auto List members checked in the Text Editor options under 'Basic').

I've added an attribute for a user readable display name to my Enum values.However my code to convert from the user readable display name back to the Enum (function ToEnum) seems very convoluted.I am wondering if I am missing a better way of doing this (I am using Visual Studio 2010 with SP1.)

View 10 RepliesI know this is a proper enum:
Private Enum Months
JANUARY = 1
FEBRUARY = 2
...
End Enum
However, I want to have an enum where the string will solely be integers.
Example:
Private Enum ColumnCounts
01 = 5
02 = 4
03 = 40[code].....
Essentially, I didn't want to put the f in there, just wanted to do 01. The way this will be called is:
Select Case (nRecordType)
Case "01"
...
Case "02"[code].....
Because I'm not making an instance of it and not calling a constructor, there's no way to autopopulate a Dictionary.And I don't want to convert to integer so I'm not going to do an array. That is just in case eventually the value gets above 99 and the next value would be A0.I'm trying to think of easy future changes to this and backwards compatability.If you need more explanations, let me know.
Edit 2:This is what I've done now and I think it should work:
Public Class Part
Private Shared columnCounts As Dictionary(Of String, Integer) = New Dictionary(Of String, Integer)
Public Shared Function ValidateColumns(ByRef lstFiels As List(Of String)) As Boolean[code]....
I can't verify that it's going to do what I want to, but it doesn't give me an error when I build it so I'm crossing my fingers.

View 3 RepliesI was wondering if there was a way to directly convert the integer DayOfWeek returns into a string representing the day like Monday, Tuesday etc.
Sample code:
MessageBox.Show(Date.Today.DayOfWeek)
This will return 6 (as of today). Is there a way to directly convert this into Saturday, for example? I don't really care what it really converts it into, but I want to do away with my Select Case:
Select Case Date.Today.DayOfWeek
Case 1
day = "Monday"

Which is better, using a nullable enum or adding the value None=0 to your enum list?Using nullables requires more code, but I kind of like it since it forces me to think about the possibility. Otherwise I'm liable to forget about the None enum and fail to account for it being a special case.

HI, using vs2008 and building a web app. On a asp page called blackjack.aspx, I have four labels with id of lbBJTStatusP1 lbBJTStatusP2 lbBJTStatusP3 lbBJTStatusP4.
I want to address those labels in a single sub by casting the casting two strings into the control name, so that string lbBJTStatusP & "1" would refer to lbBJTStatusP1.This is done on the code behind page.
So far I have tried this but with no success. boxct refers to either "1" "2" "3" or "4".[code]...
