[code]On my form I have text box control bind to data from sql db where for GeneralLedgerType I have only string value taken from db like "0000010" or "0000020", and when I try to run application error appears "conversion string to integer failed" and I know that I have to parse string to enum, but not sure how .
View 8 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"
I 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.
How can I parse a string in VB.NET to enum value?Example I have this enum:

Sample code:

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

I know from .NET 3.5 onwards (or might be 3.0) we can use Exension Methods to add our own methods to any Type in the .NET Framework and this is very handy, but I'm wondering if it is possible to "extend" an Enum as well?
View 13 RepliesI would like to make an enum of strings. There are several masks for text boxes that I would like to standardize in our system.For simplicity lets say there are 2 masks:
"PhoneNumber" which is "(999)000-0000"
"Zip Code" which is "00000-9999"
I would like to be able to reference these through out the entire program in a manner such as:
DefaultMasks.ZipCode or DefaultMasks.PhoneNumber
Since enums can not be of string type, what would your best suggestions be as to how I could do this. I had thought about a class with constants in it but I was not sure how to implement that properly.
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.

How to connect a combo box and an enum which is kept in another class? I have searched google a lot but the only solutions I can seem to find involve declaring an enum with the combo box. I however want to keep my enum elsewhere, not in the main gui element handling form. The closet thing I could guess was:
Combox99.DataSource = System.Enum.GetValues(GetType(MyBookList.OptionsList)
With MyBookList as a previously defined instance of the BookList class.
I am using Visual Studio 2010 Prof. In C# I can create my own Enumerator and use it like this:MyEnum value = Now, Intellisense will suggest a value of MyEnum. In VB, when I write:Dim value As MyEnum = I get a huge list of every types. When starting to write my enumerator value (could be a word like "sunny") it filters out some types but I would like to have it like in C#. Anyway I will use the MyEnum type and no "String nor Objecte nor IntPtr...".
View 2 RepliesI wanted to make a collection of definitions public, for which the Enum class was a perfect candidate, but I also had the need to check variables against all the possibile enum members to see which one they were.
In this scenario my solution was to write a public enum class in which all the members were made available, and replicate the same listing in an array in order to iterate through.
In fact the only way I know to iterate through all memebers is a cycle (either "for each" or "while somecondition" and a moving index). But I guess there must be a simpler way to make use of an enum class.
I'm trying to code a program but this error repeatedly shows up and I can't for the life of me figure it out EValue of type 'String' cannot be converted to 'System.Windows.Forms.TextBox'. It appears in relation to this code

More for interest than actual need.is it possible to have an automatically decreasing enum in C# or VB.NET?
public enum testEnum
{
this = -1,
that,
other,
}
So that that = -2 and other = -3.I'm pretty sure the only way to do it is to specifically assign "that" and "other", but I wondered if there was an automatic way of doing it.
Edit To be clear, I'm simply talking about the automatic assignment of the value, not the actual value of the enum decreasing.
I'm using vb but still learning it. Here is the question, I have following ENUM created so that i can use it all the form. I created this Enum on my main form (startup form) and want to use in another form.
Enum MyStatus

Bad = 2
Normal = 3
End Enum
Now from other form I'm using it like frmMainmenu.MyStatus.red. I was wondering how i can make it public or create it in a way so that i don't need to give the prefix frmmainmenu before using its value.

How do I do this C# statement in VB.Net (2005):MainMap.MapType =(MapType)comboBoxMapType.SelectedValue;MainMap only accepts Types so passing the Integer value of the type is not possible. The combo contains a list of strings:comboBoxMapType.DataSource = Enum.GetValues(typeof(MapType));In my case I need to limit the list to less than 100% of the Enum values so code similar to .Datasource= code will not work.So in general I need a way to return an enum given the name of the enum.Maybe I should just do a Collection of Enums (if that is even possible) and use the name as the Key?
