I can't fix following code:
Private Sub Dic_List(ByRef sender As Array)
Dim L_sender As Integer
L_sender = sender.Length / 5 - 1
ReDim Preserve sender(4, L_sender + 200)
End Sub
Error 1 'Redim' statement requires an array.
But sender is an array.
This is my structure...
<Serializable()> _
Public Class AcctRecords
Public Amount() As Long
Public DateC() As String
[Code] .....
This is where I try to create a new instance but I get an error that states:
Overload Resolution Failed Because No Accessible "NEW" accepts this number of ArgumentsPrivate Sub FixMasterArraySize(ByVal Cnt As Integer)
ReDim Preserve Acct.Master(Cnt)
For I As Integer = 0 To Acct.Master.Length - 1
Acct.Master(I).AcctType =
New String
Next
End Sub
If Acct.Master(I).AcctType was a Boolean type there would be no error..
In a case where you would like to reset an array of boolean values what is faster, rediming the array or enumerating and resetting the values? I have run some tests and they seem to suggest that a redim is a lot faster but I am not convinced that it isnt a result of how I'm running the tests.
My tests seem to suggest that redim is nearly twice as fast.So could anyone care to comment on which is faster and why? Also would you expect the same result across different languages?

I have the following array in my project that I'm trying to redim without losing the values.The problem with redim preserve is I can only redim the last dimension of the array. I want to redim the 2nd dimension without losing data. How do I get this to work?[code]

I have an object array that I want to reference. The object array is in a deep set of classes so it takes class1.class2.class3.class4 just to get to it. I need to use this many times throughout my code so I figured I'd just create an object i.e. Dim Obj as Object and reference this array:
Dim Obj as Object = Class1.Class2.Class3.Class4.ObjectsArray
Problem is I can't resize the referenced array, by using the reference. The following does not work:
Redim Obj(5)
How come it isn't referencing my object array completely? is it because its the same object type?

View 8 RepliesI'm upgrading my VB6 project to VB.NET and I found one of the problem below relating to dimensional array.Here's my VB6 coding :
Private Function ConvertMatrixToBase0(ByVal MyMat() As Double) As Double()
Dim i, j As Long
Dim ConvMat() As Double[code.]...
When i port it over to VB.NET, i encountered error message 'ReDim' cannot change the number of dimensions of an array. for the line highlighted in red. And I suspect that VB.NET need to always define the exact dimension of the array during the declaration. But for the function above, for the array of 'MyMat()', I do not know what is the exact dimension every time it runs, and that is why i need to check the dimension of the array.My question is do we have any solution in dealing unknown dimension array in VB.NET? As in VB6, we can just define Array() instead of Array (,) in VB.NET.
As you will see from the code below I need to be able to tell before the array runs how many members of the array there are or else the program will crash. How can I redim the array depending on how many lines are in the text file (RECORDS.txt)

Problem is I get an error saying redim can only change the rightmost dimension. It would suit my needs to change both dimensions here as my final result will be to total each column in the array. what other method can i use if arrays don't suit this task.
In VB6.0, you could create a sub that took an array byref, and then call it with an argument that was an indexed element of the array, and it would treat that index as the starting point. This was very useful, for example, if you were trying to create a binary string to send over a communication port.The same thing doesn't work in VS 2008,Let us say for example I have the following Sub:
Public Sub HexToAddr(ByRef addr() As Byte, ByVal addrstr As String)
Dim i As Integer
For i = 0 To 7[code]....
Is there some tricky way to make this work, or do I really have to either (a) create a completely separate array of bytes, call the function, and then copy the data, or (b) create a completely separate version of HexToAddr which takes an "offset" argument for the destination array?

when I copied my project and brought it to a lab at school, the code works perfectly. Looks like I have a broken install at home, or perhaps some permission issue.I'm working on a homework assignment. It requires, among other things, that I create a program to read the contents of a text file, write them to an array with an upper-bound of 50, and if is full before the text file is exhausted, to increase the upper-bound by 10. Finally, the program must output the contents of the array into a list-box.Unfortunately, while my program successfully updates the upper-bound, any attempt to output the contents of the array causes an error stating the content of the array is null. Obviously I'm running into an issue when I ReDim the array!

I am making a program that automates the seperation of a csv file. We read the csv in through and then assign the "line" using a split command to an array. After that we go through each "cell" in the array and put an = in front because this causes leading zeros not to be lost. Here's the code.
arLine = line.Split(replace)
For Each cell As String In arLine
cell = cell.Replace(",", "")
cell = String.Format(cellFormat, cell)
Next
arLine is the array and replace is the delimiter, in this case a pipe not that it matters.'
When it goes through, the arLine is correct but the values in each cell are not changing, any thoughts? newer to VB.net and need direction

I'm trying to make a show/hide button. I want the show hide button to be attached to an object on a form. Right now I just have separate show/hide buttons set the 'visible' property to true/false respectively. I want to code something that will consolidate the two properties. But I don't know how to code an if statement into an event, in this case the click event.
I'm thinking I'd have to do something like create an array (which I'd have to read a tutorial on first) that would hold two numbers. So, if the object on my forum's default visible property is true then if the button was clicked once it would be set to false (1) and clicked again it would be true (2). So, the array would only remember two values (1 and 2) and I'd have to create something else that would remember the previous value (say, 2) and than get the array to spit out the only other value (say, 1) it holds. Then finally strip the value the array spit out and have it go through some kind of if statement that would set the true/false value.
Without posting the exact code I'd need to pull it off, how would I go about doing this? Am I on the right track, or is there a simpler way? I'm new to programming.

I gather that this process could be used to define the size of an array that is not known at creation, but becomes known later in the program. VB2010, however, doesn't like this code at all, and tells me ReDim can no longer be used to this end. Why? And is there an easy replacement for this?
