Getting A Variable Array To Work?
Dec 30, 2011
ok, I got a lot of conceptual code for major chunks of the game's engine...like an inventory array of variables... he says that we will be using a lot of variable arrays, and I am trying to get a variable array dimmed in an inventory module, but when I try to declare what each index of the array should be, it says "declaration expected" and simply trying to reference the array from within another form, it does not register as existing...
the code is as follows, for he has not a clue how to program in vb.net
dim character_inventory(19) as array
and when trying to tell vb.net to set an individual index to nothing, it throws a "declaration expected" error...
character_inventory(0) = nothing is when it throws that error...

The following code does not work
Dim RowNumber As Long, RefCellControl As Long, CountIndex As Integer
RefCellControl = ClearMin.Value
Cells(1, "K").Select
ActiveCell.Value = RefCellControl
[code]....
when I replace " RefCell" with the value "0.02" which is the value of variable on form text box "ClearMin" if statment will work and will return the correct count of cells where the value is less than 0.02?

I have a problem with a global variable in VB.Net.In one sub (triggered by a button) I create objects and store them into a global variable (an array). After that I create a table (DataGrid).With a second button another sub is triggered and tries to use the array from the global variable, but it seems to be empty.Here is the code:
<script runat="server">
Dim array_datensatz(12) As Datensatz
Sub submit1_click(ByVal Sender As Object, ByVal E As EventArgs)[code].....
Why arn't the objects in the array?

So I do not know at design time if the var ms is going to be a stringreader or a memorystream. So I am trying to do basically this:
Dim ms as object = myfunction...
Dim mytype As Type = ms.GetType
Dim returnedobject = ser.Deserialize(CType(ms, mytype))
But I get an error saying "type mytype is not defined". How can I do this?

I have this function:
Public Sub DoStuff(ByVal type as System.Type, ByVal value as Object)
End Sub
The 'value' argument is always an array of the same type as 'type'. How can I loop through the values of the array?
I'd like to be able to do something like this:
DoStuff(GetType(Integer), New Integer(){1,2,3})
Public Sub DoStuff(ByVal type as System.Type, ByVal value as Object)
//Strongly types arr as Integer()

I am using visual absic 2008 express edition. I am trying to produce two (FromNode, ToNode) random numbers and store in an array (ArrayTo(NoConnections)). The array should not have same values at the same time and the aary should not have the same number or the other way around. For example, The array should not have numbers like 22, 55, 66Šetc If the array has 13 and 45 then 31 and 54 is not allowed in the array and vise versa.

The values for the 10 variables belonging to the modified array should be equal to the ages of 10 of your classmates. You must begin by gathering ages from 10 of your classmates and recording them for use in your program. Instead of calculating and displaying the total of the array values, find and display the average age of your 10 classmates.

Vb.net For each currentFarm in ......
If urlQueue.Count > 0 Then
Debug.Assert(currentFarm.isBusy = False)
Debug.Assert(currentFarm.WebClient.IsBusy = False)
[CODE]...
The commented code won't work. That's because by the time the thread start, the variable currentFarm have changed. So I create a new function and cache the currentFarm in the function parameter. No there will be a cache of currentFarm address (object is always a pointer) on a stack and that address is the one being passed to the System.Threading.Thread constructor.

Redefining array - would this code work? I attempt to redefine the dimensions of a one-dimensional array every time i need to add a value to it. Would the following code accomplish that?

I get what I'm supposed to do, and this is my 9th project in this class so I'm not new to the coding and how it works, but for some reason I'm having a hard time wrapping my mind around the multidimensional array and the variables to get the program to work. Here is the first part of the instructions I was given for the project:
Write a program that will determine the cost of a Yacht rental based upon yacht type, the size of the yacht and the number of hours the yacht is rented. There are three categories of yachts: Ranger, Catalina, and Excalibur; and three yachts sizes: 20 feet, 30 feet, and 40 feet. The rental cost is the yacht price multiplied by the number of hours rented. Create an array to hold the rental prices.
RangerCatalinaExcalibur
20 feet 95.00105.00125.00
30 feet110.00130.00150.00(prices per hour,
40 feet120.00145.00180.00 multi-dimensional array)
Use a data structure that contains the following fields: yacht type, yacht size, price per hour and cost of the rental. Limit the number of transactions to 20. Each time the Calculate Price button is pressed, look up the rental price from the price array and display it on the form along with the rental cost. Add the appropriate information to the data structure to create a transaction history.
Here's my code, the top with the variables:
vb.net
Public Class YachtRentalMainForm
'Variables
[CODE]...................
And here's my calculate button code where I'm having the most trouble:
vb.net
Private Sub CalculateButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CalculateButton.Click
[CODE]......................
I'm not getting errors anymore thankfully, but when I run the program... I choose my yacht type and size and input hours, it doesn't matter how many hours I put in - the price doesn't change. I know I'm missing something, maybe I've just been staring at it too long and need a fresh set of eyes to give it a look over and tell me what I'm missing? It also isn't calculating properly. 40 foot excalibur is supposed to charge $180 per hour and instead it's charging $125 flat rate.

if i generate a label dynamically i can change the text as followed, variable is a string: Form.Controls(variable).text = "test" I now have a sub that will create some and will get some information out of arrays. I have a lot of them. I only want the function for tat specific array. I do not want a case or if. Thats why i was wondering if i can use a variable in the array variable. [Code] But instead of TestArray being hard-coded i want it to be replaced with Shelf. So whatever gets send into the sub will change the array that i'm using. Is that possible some how or is the way totally wrong?

This is the Code:

The 'Name' column does exist, but the ComboBox shows only the type of each datarow not the contents! If I set the datasource to a datatable, the correct column is shown in the combobox/listview.

I'm writing reports in Report Designer (VS 2008), and I've reached a point where I have to circumvent the restrictions on using aggregates in groups. I believe this can be done by utilising custom code, which is written in Visual Basic as far as I know (not sure what version though).
I have a dynamic number of "Pools", which each contain "Models". Each Model row needs to set the Pool Multiplier to the maximum of the current multiplier and proposed multiplier. The Pool row (parent group row) then needs to get the Pool Multiplier.[code]...

i want to declare an array with a name that is the value of a variable. I need to do this because i want to create arrays from a text file that i'm reading.Basically, if someone could make this work then i should be able to change it to fit my use.
Dim var1 As String = howdy
Dim var1() as Integer
In this case i'd like to be declaring an array with the name 'howdy' that stores integers. In reality i'm looping a bunch of read names and would like to create an array for each name i read- but i'm quite capable of sorting the rest.

In C#, I can declare an array variable like this: object[] Parameters;
And initialize it like this: Parameters = new object[20];
In VB, declaring and initializing an array is easy:
Dim Parameters(19) As Object
Dim Parameters As Object(19) ' Alternative Syntax
How would I initialize an array variable that has already been declared in VB.NET? Parameters = New Object(19) doesn't work.
For example, how would I translate the following to vb.net?
int value = 20;
object[] Parameters;
if (value > 10)
{
Parameters = new Object[20];
}

I am new to VB.NET but used to write a lot of code in VB 6.
How do i declare a variable length array in VB.NET?
In VB6, i would just put:
Dim sArrayList() As String
But when I do that in VB.NET, it highlights my array name and says "unused local variable". What do I need to do to get it to work without an error?

I am having some trouble with an array full of data which I am trying to process. The data has been picked out of an Excel spreadsheet and contains items such as phone numbers. The problem is that when I drop this array back into a spreadsheet, Excel being clever, decides that some of the phone numbers are numbers and removes the "+" from the front.[code]...
I know that adding a ' in front of the + will remedy this. What I need to do is find out which of the numbers in the array are actually numbers and which have spaces/characters in them. IS there a quick way of doing this without having to search through each individual character of each array position?
