View 1 RepliesHow create a array of objects (another class) in VB.NET and initialise it. Since I am not sure about the length of the array, it should be generic. I mean I should be able to add any number of objects to the array.
View 2 RepliesI am working with some code that uses array lists and I am using some of these to pass data back and forth like this: whatFile = (sideLookUp(x)) and its working, BUT when I turn this code into a sub/function then I call it I get problems, like double to string errors, even though its all set to double.

I define a arrary.
Dim myStr(100) as string.
Then the length of this array is still 0. Then is risky to cross the bound. So how to intialize this array without using a loop?
is there a shorter way to create an array of 215 boolean 'true's than the following?
Dim ArrayOfBits As Boolean() = {True, True, True, True, True, True, True, True, True, True, True, True, True, True, True, True, True, True, True, True, True, True, True, True, True, True, True, True, True, True, True, True, True, True, True, True, True, True, True, True, True, True, True, True, True, True, True, True, True, True, True, True, True, True, True, True, True, True, True, True,

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];
}
[URl] The code in question is specifically at line 143. Whenever I try to access a label in the array like so Dicelbls(0).Text I get a null reference error. Obviously I am not declaring the array right?

I am trying to initialize a multidimensional array. Here is my syntax; this does not create errors but it does not store all values either. Although it correctly prints out all records in this snippet,
dFirstWeek = CDate(FirstWeek)
dFirstWeek = DateAdd(DateInterval.WeekOfYear, -1, dFirstWeek)
Dim dFirstDay As Date
Dim arrWeekYear(5000, 1) As Date
Dim i As Integer = 0
Dim j As Integer = 0
[Code] .....
But this time, only one "j" record appears per "i" record. Why is this? And then after these few records, many dates resembling null dates appear: "1/1/0001". So why do all records appear in upper section, but not from lower? Did I insert values wrongly into this array? And it does not have to have fixed number of rows, just a fixed number of columns.

BtnStruct(BtnNum).x(pos - 1) = temp "btnstruct is not declared. it may not be inaccessible due to its protection level"
