What 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.
Dim july As DateTime.Months = DateTime.Months.July
Public Enum Months
January = 1

So apparently Microsoft does not have a Months Enum on their Date structure.What 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.[code]...
View 3 RepliesI am coding in vb.net. I want to achieve something like this (sample) -
Structure Transport
Dim land as L
Dim Air as A
[CODE]...
But though i can create enum but how can I embedd it in structure. It is not allowing me to do that.
I think it's substituable for just Dim, Public or others. What is merit by using structure, property ??
View 1 RepliesI 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.
I 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

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've been searching for a while now and can't find a way to add a constructor to the Rectangle Structure.

I'm fairly new to ASP.NET & VB.I've been asked to take an existing textbox that is automatically filled with the current date and allow the user to either add a "+" or "-" and a number or a spcific number and convert that into a date.I underdstand the basic concept on how to do this, but I'm running into some problems using the proper commands in order for this to work.The Textbox is called txtDate.What I've tried to do is this:
If txtDate = '+' Or '-' Then
DateAdd("d", txtDate, today)
End If

how to write the code for my project.I am to base my new project on an existing one(existing one has code that works 100%)and create an Array of a structure that bascially holds the information from a summary form AND the totals from an AddToOrder_Click event. If you are still with me)... I cant figure out what the code is for my structure and Array so that I STILL have a Summary Form but I have an array that shows when I click my PrintPreview. So an Array is basically a "space" that holds information, like my summary form except it doesnt show until I click PrintPreview right?
If I just wanted to show the table then my code belongs in the PrintDocument1_PrintPage to show the array but the actual structure code belongs in the Click_Event of my AddToOrder? Please Please understand I AM NOT asking for anyone to write my code, basically I am asking for some clarification on what exactly creating an array from a structure is and therefore determing where the structure is to be placed in my code..
I'm trying to declare an enumeration and one of the names I'd like to use for an item is not usable apparently.

View 4 RepliesI am creating a program that takes into account pay from a job. I will try to describe the problem I am having using some psuedo code - so dont take syntax too seriously.
I created a structure that has some of the following values:
Name as String
Amount as Double
FrequencyType as MyEnumerator
MyEnumerator looks like this:
EveryTwoWeeks = 1
TwiceAMonth = 2
Weekly = 3
Now my problem is how do I add the date ranges into my structure?If your pay is weekly or twice a week, then I just need a single date because all other paydays should increment in 1 or 2 week blocks. But if the pay is twice a month I need two dates. It seems like there has got to be a better way then just having two dates in my structure and knowing that you just need the 2nd date if the FrequencyType is = 2 (TwiceAMonth).I was thinking that instead of a Structure I should use a class and then I could create a function that returns the date or dates depending on the enumeration type that you pass into it.What would be the "correct" way of doing this? I think I need a type of enumerator that allows for more then just integer type values.

I understand how to rename a file in vb.net as I use the coding at the end of my post. However, is its possible to rename a file and if the file exists then to rename it and add +1 to the file name? So if I ran the code.
'Run it first time
My.Computer.FileSystem.RenameFile("c: est est.txt", "c: estNewName.txt")
'Run it again but it should add +1 as the file will already exists so it should be "c: estNewName1.txt"
My.Computer.FileSystem.RenameFile("c: est est.txt", "c: estNewName.txt")
Decided rather than rename and +1 it would be better to just date stamp it.
My.Computer.FileSystem.RenameFile("c: est est.txt", "Test" & Format(Date.Now, "ddMMyy") & ".txt")
I'm using Visual Studio .Net 2008 on Vista. The goal of my program is to watch a directory, get file information, then sort them by thier date, and produce a updated text file. I can't seem to get my code to generate a list of files sorted by date. The code does produce a general list of files, however presently ordered in the directory. I also tried an alternate way of sorting the files by date by creating a string, removing the date using substring, then comparing the file dates using datetime.parse but it produces a exception error.[code]...
View 5 RepliesI am trying to convert text in a text box (txtEventDate.Text) to a date type in a structure: ThisEvent.EventDate (declared as date). The text in the textbox is of the form: 05/18/1927 (i.e. May 18th, 1927) and after looking long and hard thru the forums attempting several different things, like:
'ThisEvent.EventDate = CDate(Format("#" & txtEventDate.Text & "#", "mm/dd/yyyy"))
'ThisEvent.EventDate = Date.Parse(txtEventDate.Text & "12:01:00 AM")
'Date.TryParse(txtEventDate.Text, ThisEvent.EventDate)
The code is commented out because none of them convert the string to a date value (I know a date does not have a format and I have looked thru the MSDN). How can I stay logged and composing a thread past some arbitrary time limit that forces a re-login?

View 4 RepliesWhich 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.

I'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.
I 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.
