VS 2008 - Retrieve Enum Custom Attribute In Single Statement
Jan 28, 2010
I have an enum set with custom attributes. need to retrieve the attribute value in single statement ...
Public Enum Messages
''' <summary>
''' <value>(MessageText : Do you want to save ?)</value>
''' </summary>
<StringValue("Do you want to save ?")> Save
[Code] .....
Now I needed to retrieve the enum value like something below.
Messages.Save.GetType().GetCustomAttributes...... something is possible in single statement itself?

I am using a repeater with the Item Template of a checkbox. Here's my checkbox template:
[Code]...
Now, I know asp checkboxes do not have a value attribute, but I read somewhere that you can put that in there and it will work the same. I'll have to look it up again to see if I read it wrong. However, just in case it is possible to put the custom attribute in there, how do I retrieve it in code behind? I looked at the source after the page is created and there is no attribute in the control that says "value".

I'm trying to declare an enumeration and one of the names I'd like to use for an item is not usable apparently. Where I am declaring 'STEP = 3', I get this error message in visual studio: "Statement cannot appear within an Enum body. End of statement expected." Is it possible to use STEP as an item name somehow? [Code]

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.)

Im currently developing a custom logging component, that we will deploy with all our applications, windows services, webapps, windows apps etc. I have a few questions of various nature. The component is a single signed dll file:
1) Which is the "safest" way to get the current directory? For example, in the config file, in the config section I have a property "logpath". The application will read this and write a log file depending in what they write:
c:myapplog (it will write a log here, create whatever folders it need) /Log (directly under the installed app directory, like c:program filesmyappLog) Log (same as above) I need something that work with both windows and web apps, for webapps it will log under the virtual directory of the aspnet app.
2) For exception handling, if nothing special is happening, like in the DAL, I get a sql server exception, is there any point in using

I'm trying to figure out what the best method is for attaching a single key/value pair attribute to an enumeration where the key is my MerchantId and the value is the corresponding TransactionKey. What I currently do is put a comma delimited string into a StringValueAttribute class:
Public Enum Merchants
<StringValue("coke,faj80785hq+faf=-1=-jfa+">
Coke = 0
<StringValue("pepsi,adfji=-901jnas++fdj98ua")>
Pepsi = 1
<StringValue("drpepper,jk878-=+9kdkdja0=a=f--daj")>
DrPepper = 2
[Code]...
Is this the most efficient way to do this? Instead of StringValueAttribute, what about creating an attribute using a Dictionary(Of String, String) since it is a key/value pair list? Or String Array or List? Maybe something in LINQ?

I am creating a custom graphic control and I'm stuck. I have three classes -
Protected Class ControlBase' Handles common properties and onpaintPublic Class ImageControl Inherits ControlBase' handles Image propertiesPublic Class TextControl Inherits ControlBase' handles Graphic Text properties
I also have a private enum ControlType and Public property for that enum. My goal is to have either a TextControl or a ImageControl created based on the ControlType. Since this property is outside of those two classes and the base - where do I put this property and how do I call up the correct class?

Consider this scenario:
Class MyClass
Property SubProp1
End Property
[code]....
Next, I put an instance of MyButton into a property grid, expand property MC and edit SubProp2.From the type editor for SubProp2, I want to get hold of the attribute applied to property MC.Looking at the context,PropertyDescriptor.ComponentType, we arrive at Type: MyClass.If i look at the attributes applied to MyClass, though, it will only return the attributes applied directly to MyClass, and not the extra attribute applied to the property MC.

How can I shift the GET-implementation of a Class property to a / using a custom attribute? (I've added instantation vars (classname, propertyname) to the attribute, however I'd rather have these automatically fetched ofcourse.)
Public Class CustomClass

Public Property SomeProperty() as String

I would like to know if there's any way to specify an inline array (lets say of strings) to custom attribute on a property in vb.net.
I have the following example that doesn't compile in vb.net (.net 1.1):
Attributes.ManyToOne(New String() {"a", "b", "c"})> _
Public Property PaymentTerms() As PaymentTerms
[Code]....
I get compiler error when I feed the array to the custom attribute in vb.net. I have no problem in C#, just vb.net. What is the correct syntax in this silly language?

I'd like to auto-register the common/simple services in my unity container. I think the cleanest way to do this would be via a custom atribute.I can then examine all the (abstract) classes in an assembly and register those types with unity.The piece of information I'm missing is the interface(s) that the class wants to be registered against
eg:
Public Class AutoRegisterAttribute
Public Property ForInterface As System.Type
Public Sub New(ForInterface As System.Type)
[code]....
Note, I don't just want to find any class it implements as shown with IDisposableI've tried doing this using generics (generics can't inherit from Attribute), with a Type Parameter (Passing in IEngine.GetType results in a "Constant expression is required")

setting the default value for an integer attribute of a custom control seems to have stopped working. The following code adds the Maximum attribute to the design-time properties table, but the default value pops up as 0, not 99:
<System.ComponentModel.Browsable(True)> _
<System.ComponentModel.Category("Behavior")> _
<System.ComponentModel.Description("highest value possible")> _

Is there any way to use selectnode with the attribute having both single and double quotes? If we are having single quote in the attribute we can use like below,
nodeList = root.SelectNodes("//book[contains(title,""'attribute'"")]")
If we are having double quotes we can use,
nodeList = root.SelectNodes("//book[contains(title,'"""attribute"""')]")
how can I use an attribute ['attribute"] having both single and quotes in SelectNodes.

I'm new to LINQ and am having a problem getting proper results from a simple (working) stored procedure that takes no parameters and returns a single Integer. When calling this sproc with LINQ its returnvalue is always 0. When run using tableadapter or directly on the sql server it works, returning 6 digit values like 120123.
Here is my LINQ code:
Dim MeetingManager As New MeetingManagerDataContext
Dim MeetingID As Integer = MeetingManager.NewMeetingID().ReturnValue Here is the NewMeetingID procedure:
ALTER PROCEDURE [dbo].[NewMeetingID]
AS
SET NOCOUNT ON
