Declare Two Module Level String Variables Name StrCaptital And StrChoice
May 16, 2011
What I'm supposed to do is declare two module level String variables name strCaptital and strChoice and I did that. At least I think I put them in the right place, however what I'm not sure what to do is and I started is that I'm supposed to code each state radio button's click event procedures so that each assigns the appropriate capital to the strCapital variable and then each removes the contents of the lblMsg control.url...

What I am used to declaring database connection is that in every form I type the codes for it which is a tiring way. Now, I want to use module instead but I really don't know how. And also, how will I call the connection to every forms I created?

I have an issue with variables that are used to name For-Next loops. I have had this problem in a couple programs but not consistently, i.e. some variables work, some throw a warning (not an error).
The situation is this. I declare the variable along with all my declarations in a module-
Module MainModule
Public Counter1 As Integer
end Module 'MainModule
[Code]....
The type for variable 'Counter1' will not be inferred because it is bound to a field in an enclosing scope. Either change the name of 'Counter1', or use the fully qualified name (for example, 'Me.Counter1' or 'MyBase.Counter1'). In the past I've always broken down and changed the names to get rid of all those ugly warnings. Sometimes I have eliminated them from being declared in the module and declared them at call time. This is not how I program and I like to keep consistency throughout.
how I can get rid of this spotty, on-and-off nonsense? There is obviously a lot I don't understand about VS and I would have never taken it up but would have stopped 3 languages ago if I weren't forced into bulkier and bulkier languages (sorry about the rant. I feel OK now).

I just need to know where my code is jacked -up at, I get an error when I created the module level variable ( class statement must end with a matching end class) problem is that every time I add an end class the next procedure is wrong with the same error, so what can I do to resolve this and why is this error coming up. Ultimate goal of this program is to add the invoice totals to the next element in the array each time the user clicks calculate, which displays in a message when the user clicks the exit button, also this code will sort the invoice totals in the array.
Public Class frmInvoiceTotal
Dim SumInvoice(4) As Decimal 'Delareation of two module- level variables
Dim I As Integer = 0' the index I can use to work with this array
Private Sub btnCalculate_Click(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles btnCalculate.Click
[Code] .....

Define a structure named product, The structure should contain 2 variables one as a string and the other as a decimal. The decimal is used to store the price and the string is used to store the item number.
Declare a module level array that contains 5 product structure variables
Code the main forms load event procedure so that it reads the item number and prices from the itemInfo.txt file The procedure should store the item numbers and prices in the module level array. It also should add the item numbers to the list box.
When the user selects an item in the list box the items price should appear in the xPriceLabel. code the appropriate procedure.
The code I have is as follows
' Project name: Glovers Project
' Project purpose: The project displays the price of an item.
' Created/revised: <your name> on <current date>
[Code].....
Seems the problem I am having is this line is returning a value less than 0.
itemprice = (itemnumber.Substring(productIndex, newLineIndex - productIndex))

Is it at all possible to declare variables dynamically? Something like Dim Answers & i As ArrayList. What I'm trying to achieve is putting one or more answers to a question into an array. Or should I really be looking at a mult-dimensional array to store the question number and answer? How would I add to and access a multi-dimentional array? Anyway, here's the section of code:[code].......

What happens if I do: Dim x As New Int32? Is a object of int placed on the heap? If it is, maybe your application would be able to access global variables faster if they were reference types.
A global variable as an value type should be somewhere at the bottom of the stack most of the time and it might take more time to get to this then to get a object from the heap. Unless it's the same story with the pointer of this object is also at the bottom of the stack of course.

I put "isolated context" in quotes because I don't know what else you would call it. Basically, in C#, you can do this:
{ int i = 0; }
{ int i = 1; }
The curly braces create an isolated context which allows you to declare two variables with the same name in the same method or property logic. Is this possible in VB.NET? Also, what do you call this aside from an isolated context?

I declare a variable as FRIEND in a Module. Then I instantiate that variable in a Sub in the Module. After the Sub runs, when I try to access that Variable, it is always NULL (Nothing).
Module MODULE_Main
Friend MyClass1 As Class1
Friend Sub Main()
[code]....
How do I get MyClass1 to persist, meaning how do I get access to that variable outside of the Sub that instantiates it?

I am taking an online class and I am having trouble getting my solution to work. My assignment is as follows: In the function, declare variables for the average score and the letter grade. Calculate the average, use If/ElseIf statements to determine the letter grade, and return the letter grade.
Create a subprocedure for the Click event for the btnDisplay button. It should call the CalculateGrade function with three arguments (the three test scores from the text boxes), and display the returned value in the lblGrade box.I have looked all over the internet and have had no luck finding an example to look at I am taking an online class and I am having trouble getting my solution to work.
