Use Structure, Property Or Enum Syntax?
Nov 10, 2011I think it's substituable for just Dim, Public or others. What is merit by using structure, property ??

Add An Enum To An Existing .NET Structure, Like Date?
Feb 23, 2011What I am wondering is, is it possible to create an enum and attach it to the DateTime structure? Extension Methods come instantly to mind, but I don't know of a way to pull this off using them.

View 3 RepliesEnum Inside Structure - Adding Properties?
May 19, 2009I have an enum that I want to give some methods. I thought about changing the enum to a structure so I could add properties, but then the enum is a value inside the structure (not the structure itself), so this would affect comparisons and such. (For example, instead of writing
EnumVariable=EnumConstant,
Now it is
StructureVariable.EnumValue=EnumConstant).
At least, this is my understanding of it. It seems awkward to have to do this for such a simple scenario, so is it possible give enums properties, yet still have them treated as before? I've thought maybe I need to create a new valuetype from scratch, but I've never done that before.

Custom Graphic Control Enum Property
Aug 28, 2008I 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?
VS 2008 Enum Property Changing Unexpectedly?
Sep 2, 2010I have an Enum file, as shown in first code block. Though it's first time I use an enum file, so maybe it's not correct to use it like this.. My purpose is just to be able to reference a global parameter from anywhere, so I can just type DataInterval.M1, and it will be treated as an integer... or.. will it not ? urther I have a property in my DataSeries class, of type DataInterval. And in this class I also have a bunch of methods Get/Set etc. to do different work on the dataseries (Inherits List(Of BarData)). roblem: The interval property keeps changing unexpectedly every time the GetNextCloseTime function is called.
''' <summary>
''' "Time Frame" of data series

C# - App.config Syntax For Structure?
Nov 6, 2009I have difficulties figuring out a useful app.config structures for my program.What I am doing is writing a windows service, which watches several directories on a server for files being uploaded.My problem is making my program configurable for n folders when in each of those n folders, i need to watch for a different collection of filetypes
e.g. folder1: .dwg;
folder2: .dwg;.doc;.xls;
then when a new file is uploaded, for example a .dwg file to folder1,then i need to run program1 to convert the dwg to a dwf, and program2 to convert the dwg to a .swf.but that only if filetype is .dwg and folder = folder1. if a .dwg is uploaded for example to folder2, then it needs to be converted to a pdf.The closes i have come to make this configurable in a app.config file is this:
<Folder2 name="C:inetpubwwwrootCAFMFotos" filetypes=".dwg;.pdf;">
<action>
<add key="ExecutableAndPath" value="C:UsersMeDesktopverydocdwg2vec.exe"/>[code].........
I have difficulties bringing this to a usable from in app.config

Stored Procedure Syntax Structure?
Apr 23, 2009I have a dataset with a bunch of tables in it. I also have a database with the same tables, but not necessarily the same number of rows. Any table in the dataset will have the same rows as there are in the equivalent table in the database, but there may be a few extra in the dataset. What I'm looking for is a fast way to determine whether there are extra rows, and if so, they need to be inserted into the DB.

Use An ArrayList As A Property In A Structure?
Mar 26, 2010I was wondering if I can use an ArrayList inside a structure as one of the structure's properties.Or it may be better to replace the structure with a class. If so, can I use an ArrayList as a property of the class.So what I want to do is have the ArrayList as the property of the structure and be able to add items to the ArrayList and clear the ArrayList from a clear method of the structure.
i.e.,

IDE :: Binding Via Property Element Syntax?
Dec 20, 2009First, I am making the assumption that anything you can do in "Attribute Syntax" (AS), you can do in "Property Element Syntax" (PES), but not vice-versa. That is the reason I intend on coding completely in PES if possible. I have encountered quirks though.The first issue is regarding AS "x:Name" or PES "<FrameworkElement.Name>": If I use PES, I must make sure it is the last element, otherwise any PES below it will error on build; eg "Value of type 'System.Windows.ResourceDictionary' cannot be converted to 'Namespace.ClassName'."
A problem encountered intermixing AS and PES: Set "x:Name" and "MinWidth" as AS. Set "Title" as PES.

Syntax To Change The Value Of A Cached Object Property?

Is there a way to access this directly in the cache or do I have to destroy and rebuild the whole object just to change the value of objMemberDetails.CreditNum?The cache is set using:

Dim userID As String = HttpContext.Current.User.Identity.Name
HttpContext.Current.Cache(key & "_" & userID) = value

Class Structure - Large Structure That Has Lots Of Properties ?
Jan 5, 2010I'm new to VB 2008 after having spent a long time with VB6, so I apologize if this is a stupid question. But I'd really like to have this straightened out.
Let's say I have a pretty large structure that has lots of properties.
Code:
Now say that I want an internal database with about 10 instances of this structure total, describing, say, 10 different products that a store sells. When these values are loaded from a database, they remain totally static. (However, they can be different each time a program loads)
Now say that I have a class. Each instance of this class is a type of that BaseProduct structure. Meaning, each instance of the class pertains to one of the 10 types of products that the store sells. However, this class has additional properties that pertain specifically to each instance, which are not static.
Code:
Now, the problem here is... If I have 200 different transactions, each one contains an instance of BaseProduct. BaseProduct is HUGE, and is largely redundant (only 10 types possible), so I think it's a little silly to include a whole copy of it with EVERY transaction. However, the Transaction class really needs information regarding the base product it pertains to. Is there a way to, instead of declaring a New BaseProduct in the Transaction class, to simply make one of the properties of the Transaction class a pointer to a BaseProduct variable?
In VB6, I would accomplish this by making a BaseProduct(10) array, and then giving each Transaction an ID number referring to an entry in that array. But in VB 2008, using class structure, this is impossible. I can't define the BaseProduct(10) array outside of a class in a namespace, and if I define it in the actual application's form, then the class loses modularity since it relies on the application that's using it.
Converting Structure Within Structure To Byte Array For Socket
Aug 29, 2009I am trying to communicate with an external device and i am trying to send a byte array to the external device via sockets but i am always getting a response the message size is too small so i am not sure what i have done wrong. Between the data type there should be no alignment present and all numbers are represented in little endian format. The char array is not null terminated as mentioned in the protocol specifications.
I have to send data based on a struct that embeds 2 other struct. So here's my vb.net code for the struct used to convert to byte array and the sending part.
