Converting C# To Vb. "array Initializer Is Missing 1 Elements"?
May 4, 2009
I am trying to convet the following code from C# to Vb using 3.5 framework.Here is the code in C# that I am having trouble with.MethodInfo mi = typeof(Page).GetMethod("LoadControl", new Type[2] { typeof(Type), typeof(object[]) });
I thought it would be like this in VB;Dim mi As MethodInfo = GetType(Page).GetMethod("LoadControl", New Type(2) {GetType(Type), GetType(Object())})
but I am getting the following error "array initializer is missing 1 elements"The other line that I am having trouble with and getting the same error is control = (Control) mi.Invoke(this.Page, new object[2] { ucType, null });
[Code]...

I have a string of bytes which I am reading from a microcontroller via a serial port which is as follows : 02 10 18 14 CB 73 43 D3 14 00 0D 00 09 00 1B 00 04 B8 3C 00 00 24 00 30 AB
I would like to write some code to place each the bytes into an array with each element of the array consisting of one byte each.

I have the following function,
Dim results() As Object = Me.Invoke("webdirect", New Object() {Company, LocationCode, CustomerNumber, OrderNumber, OrderRef, OrderDate, WebLines})
o_Company = CType(results(1),System.Nullable(Of Integer))
o_LocationCode = CType(results(2),String)
o_CustomerNumber = CType(results(3),String)
[Code] .....
So the return type of this function is a string, but I would like to get it back to its original form so I can access the individual sections i.e. o_LocationCode,o_CustomerNumber, etc how can I do that ?
Entire functions looks like this
Public Function webdirect(<System.Xml.Serialization.XmlElementAttribute(IsNullable:=true)> ByVal Company As System.Nullable(Of Integer), <System.Xml.Serialization.XmlElementAttribute(IsNullable:=true)> ByVal LocationCode As String, <System.Xml.Serialization.XmlElementAttribute(IsNullable:=true)> ByVal CustomerNumber As String,
[Code] .....
Called like this
Dim returnArray As String
returnArray = client.webdirect(10, "123", "123", "123", "147", "2011-11-1", webLinesArray, 10, "", "", "", "", "", webRespArray)
No errors on run time but the string seems to be just blank, thats why i was wondering how I convert the string back to the array so I can access the individual elements.

some of the xelements within the query were calling for tags that didn't exist in the original xml, heres a simple example of what i mean.
element = _
<xml>
<object>
<string>someString</string>
[code]....
So how do i change the querry so that it wont produce a null error if the tags asked for are not present.

I find myself wanting to do something like this:
' toy example
dim foo() as Integer = { _
'Integers from 1 to 5[code]....
but I get "Expression expected" errors.I would have expected the compiler to treat comment lines as nulls. Is there a "right" way to do this?

I've come up with the following and it's partly working.
Public serial1, serial2, serial3, serial4, serial5 As SerialPort
Public serialports() As Object = New Object() {serial1, serial2, serial3, serial4, serial5}
dComPort = "COM4"[code]....
The above code works fine! But im having trouble trying to now retreive whats stored in the array.In the above example, an entry will be stored in serialports(4), all other array elements will be blank.If I do this it works.
MsgBox(serialports(4).PortName) ' this retuns the value COM4
But I'd like to loop though all array elements and print out ALL the PortNames, The below code doesnt work, I get an error Object variable or With block variable not set.
For i = 0 To serialports.Length - 1
MsgBox(serialports(i).portname)
Next

I feel quite silly asking this, but I couldn't find a definite answer anywhere. in vb.net, how are the array elements defined (if they are defined) for, for example:
Dim myarray(5) as int
does, at this point in time, myarray(3) for example have a defined value? If so, what is it?

I am trying to add the values in my array.. and this is my code
dim totals(6) as decimal
public function AddIBNRTotal(byval Amt as decimal,srvcdesc as string) as decimal
if srvcdesc = "ZZ_TOTAL" then
[Code]....
I know the addIBNRfunction works fine cause it is displaying the correct amounts in my textbox
but when i call the Sumnumber() i am getting 70000 dollars short...
So is this the right way to add values or elements to a array...

How would you code this so that it adds up the first column, and then the second column?
Dim intSales(,) As Integer = {{100000, 150000}, _
{90000, 120000}, _
{75000, 210000}, _

I am just starting VB at 60 years old and with no programming experience and nobody to ask for help...except here, of course. So needless to say I am hitting brickwalls. I am using "Murach's Visual Basic 2008" and it seems to be a good book. This is what I am up to I have to declare an array with 5 elements with an index. I think that part is OK. Then add code that adds each element to the next one every time a user clicks a button. I have had many tries but the best I can get is just the grand total of the elements. Here is the code I came up with:-
[Code]...
Is anyone able to show me how the button click would reveal a progressive total of the elements each time a user clicked on it? It would be good if the book came with answers or had a forum for their readers.

Now I'm VERY new at the reading in a text file and storing into arrays thing and tried for hours last night to figure this out, googling and every possible way of writing the code. However, I don't know what to try next and I'm getting more confused by the minute. I have a text file which I load into my program. This data is stored into 6 arrays, each of which has data that comes from either a combobox, date or text field. What I'm trying to do is to find the count of items in each index of the array.

In this case I'm trying to create a number analysis app. I'm required to declare an array and get the data for the array using ten text boxes. Why, because my instructor said so.
My problem is my event is returning zero. Therefore I believe my code is somehow flawed.
My approach is to create functions that calculate the required metrics. I have only tried to code one function to date. If I can get help making one function work, I will be able to do the others .

Dim decScore0, decScore1, decScore2, decScore3, decScore4 As Decimal
Dim decScore5, decScore6, decScore7, decScore8, decScore9 As Decimal

I have a class I am working on for a program I am writing while I am stuck at hospital 3x a week and was wondering. If my class has a Reset function that sets the count variable to 0, can I then say that the Data array is equal to "nothing" and wipe all the data that was in it?
Below is the class structure so far:
Private Count As Integer = 0
Private Data() As Integer
Public Sub Add(ByVal value As Integer)
Count = Count + 1

For example, I have an integer array called sec1() that has 71 elements.
I tried:
vb sec1(1 - 71) += 1 But when I run the program, it gives me an error. Not a red-underline error, some other error that doesn't stop the program from compiling but stops it from running. Is there a way for me to modify all of the element of my array at once? just out of curiosity will the same method work for string arrays?

I have an array x in size of objects (between 1 and 100) and I want to increase the size to 101 ... I've resized the array and that adds the objects but unfortunatly (not suprising) the added items have not been initialised, do I've reverted to using a do while loop and adding the elements indiviually, but looking at the code around it where addrange is used extensivily, I was just wondering if that was a neat vb.net way of doing the same thing
Bit of a learning question, just looking for neat ways to do the same thing

why my code doesn't work? I want the array elements to be loaded into a listbox when the button is clicked. Is it because not all elements in my array have been filled? I've tried putting the array declaration as a global variable and as a local one (below), but the same error occurs as soon as the button is clicked - "ArgumentNullException was unhandled".
Private Sub btnLoadCustomerNames_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnLoadCustomerNames.Click
