Aug 10, 2010i was wondering if we could assign variables into the values of attribute properties like say:
<System.Xml.Serialization.XmlType(namespace:="Result" + x)>
where x is a string with value "qwe" so basically we get the output:
<System.Xml.Serialization.XmlType(namespace:="Resultqwe")

Assigning Variables To A 2 Dimensional String Array?
Feb 21, 2012I have a form that asks for a name, and a phone number, it has 3 buttons, a add customer button, show list button and an exit button. When the add customer button is clicked, it increments intCustomer variable, formats the phone number, makes sure only the first letters of the name are capitalized and creates an ID that is the first 4 letters of the name plus the customer number, the show list button takes ALL customers added to the array and displays them into a multi-line text box, like so:
ID Num Customer Name Phone Number
JOHN-1 John Harry Peters (111) 111-1111
Paul-2 Paul J Rodgers (111) 111-1111
Etc...
The area where I am completely lost in, is how to add the consecutive customers to the array, in the correct way. here is my code in its entirety
Public Class frmCustomerName
Dim intCustomer As Integer = 1
Dim names(9, 2) As String

Assigning Values Into An Array?
Mar 2, 2009I have a text file which I open and then read in 1 line at a time and split up. I then takes each component part from the split string and assign it into a variable as I go.
I then want to specific varaibles and put them into an array and build the array.
Can I read in each element and assign it directly into an array or is this was best.
also
I seem to be getting an error when I try and directly add items into an array

Assigning Values To Cards?
Apr 27, 2009basically i've gotten myself into a mess with some last minute project work. shame on me and all that but thats college students for ya. basically i seem to be having problems assiging a simple integer to some pictures in an array. now. basically its a card deck. i've looked this up so many times yet nothing comes to me that fits my code or the way i've been taught. in any case i've got an imagelist and put it into an array to symbolize a deck. now. as i'm doing blackjack i need each card to have its own value. so obviously 2 of hearts value = 2, king = 10 etc.so what i've done is created a function that calls on a string. and used a select case to give a value based on the filepath of the image. however it failed hoplessly. heres a piece of the code:
Sub getcardvalues(ByVal card As String)
Select Case card
Case "decklist.images.item(2club.png)"
value = 2
[code]....
despite this seemingly simple solution i can't seem to pull out the path of these cards as a string. the array simply gives me a number and the actual picture dosnt want to be a string. so my question is this. how can i pull the image path out of the array (eg: deck(1) = decklist.images.item(3club.png)) and turn that into a useable string?
Array Of Objects - Assigning Values?
Dec 26, 2009I am having a problem with objects and arrays of objects. Basically obj_stored holds how many objects I have stored in my text file, in this case t shirts. line(y) is an array that holds each line that has been read from the text file. I then use this to assign values to my array objects properties. For example I know the first line is the color of the first t shirt, second size, third price etc. Then I know the next line will be the color of a new t shirt. There are 6 t shirts in the file.
Dim t_shirt(5) As Clothing.t_shirt
Dim t_shirt_purchased As New Clothing.t_shirt
For x = 0 To obj_stored
t_shirt(x) = Clothing
t_shirt(x).color = line(y)
y = y + 1
t_shirt(x).size = line(y)
y = y + 1
t_shirt(x).price = line(y)
y = y + 1
Next
MsgBox (t_shirt(4).size)
My problem is it seems to be resetting these values after it has finished. Im creating the object each time and assigning values to it's properties but when it's finished it all resets and says 'Object reference not set to an instance of an object'. I'm new to OOP and was wondering what sort of approach i would take to doing this, if the one i am taking is wrong.
So I am aiming to:
Read everything in from the text file.
Create new instances of the objects depending on how many t shirts are stored, (5 t shirts = 5 objects)
Assign the values to my objects properties.

VS 2008 Read CSV Values / Assigning To Text Box?
Aug 22, 2009Before I start great forums, from what i've seen browsing unregistered this place is a treasure trove of information; however, after searching for what I need I could only find threads that seemed way to complicated or irrelevant, so...Essentialy I have created a program in which values entered are saved to seperate text files depending on which tab of a Tab Control they originate (from text boxes). I'm pretty new to VB but i managed to save the values of each text box to a .txt as CSV, essentialy all values will only ever be decimals (as currency) or dates. Example code for one of the .txt's:

Assigning Values To Label Or Text Box Or Anything Else / But DDL Or Radio Button
Jun 10, 2012I am stuck on how to assign values on a label or text box.The issue is the following:I have two tables, one called A and the second one called B.Table A has tree fields: id, name, lastname...Table B has five fields: id, level1, level2, level3, level4..The idea is to save A.id into level1, level2, level3 and level4. A.id can be the same or not. I know how to assign and save the values on the DDBB using DDL, but when I want to show the values using labels, I get the first value always, this is becuase the select command is configures in that way. If I use ddl instead label, it works, but I do not want to show the value using ddl. I want to use label to show the values, and ddl to modify or add new data into the DDBB.[code] As you can see the level1 uses label, and level2 uses ddl, it was the only way to get the value for level2, otherwise if I use label on level2 it display level1 value instead.I would like to know if there is any way to assign different value using anything but ddl.
View 6 RepliesPerforming Operations And Assigning Values To A BigInteger Type?

I looked at the members of XmlReader, but I can't seem to get the right methods to do this efficiently. How should I parse every element between <movie></movie>.
