i 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")
I'm passing a value to another form and later on use that value that is assigned to a variable.
Here is the code.
loadingPage.Show()
mode = "notime"
Dim ld As loadingPage
[Code]....
CurrentMode doesn't have a value. I don't know why. CurrentMode is a global variable.

Does case 1 and case 2 yield same result, I mean is a private value necessarily in there?, can we use property itself to use its own value in its Set and get statements?
Is there a way I can assign a value to a class attribute using a constant? would like to do this so that I don't have tocode a constant value in the attribute and then again inside the class.

I'm facing a problem with my current member card reader development.
I'm reading the card number (just a serial number of 4 digits) with a card reader. this seems to work fine (even converting the text string to integers).
This number is then put in a query to find the exact record that corresponds with this number
Me.JSM_LedenTableAdapter.GetDataByKaartnummer(IntCardNr)
I 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

This was a difficult question to google. I have an Order class with a couple of dozen properties such as ClientReference, ShipMethod, etc. I use databinding to bind this class to an Order form. If a user enters an invalid shipping method, an exception is raised in the ShipMethod property and a validation error is displayed to the user. But I'm trying to use the same Order class within an OrderImport class whose job it is to take a flat file and create multiple orders. The problem occurs if I'm assigning to a dozen of the order fields consecutively, and say the first one causes a validation exception. If I have all dozen assignments occuring within a single try-catch block, the next 11 assignments will be skipped and I'll only be able to record one validation error. I could solve the problem by doing a dozen separate try-catch statements, but that doesn't seem very elegant.

basically 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?
I 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.

I 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.

This works perfectly:
Dim N As BigInteger
N = 28 'Put whatever value you want in for N.
Write((BigInteger.Log(N) / BigInteger.Log(2) + 1) / 2)
This does not work:
Dim Result As BigInteger = (BigInteger.Log(N) / BigInteger.Log(2) + 1) / 2
This gives an error during the build (despite the variable being declared as a BigInteger and the operation working perfectly well when I am not assigning it to a variable, it tells me I can't convert a Double to a BigInteger) and I have to do this:
Dim Result As BigInteger = CType((((BigInteger.Log(N) / BigInteger.Log(2)) + 1) / 2), BigInteger)
This if course gives a different, that is, incorrect result.'This doesn't work either.
Dim Result As BigInteger = BigInteger.Log(N)
'I can do this:
Dim ResultString As String = BigInteger.Log(N).ToString
