VS 2008 - 2 Dimensional Array - Error: Redim Can Only Change The Rightmost Dimension
Sep 22, 2011
I have a gridview in my asp.net website that and I use vb for the code behind. Each time a row is bound an even called the Gridview_RowDatabound event is fired. So what I am doing is looping through all the cells in that row: [Code]
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.
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]
The code below is the entire class that has the error in it... the errored code is highlighted in red. The error is,'ReDim' cannot change the number of dimensions of an array.
Code: Public Class clsMap Dim SR As System.IO.StreamReader Public Width As Integer Public Height As Integer
I have an application in VBA that gives to my VB.Net dll one bi-dimensional variant. It is a an array, in which every component is a another array containing two positions.
I want to get this two-position array. When I am using VBA I can access directly the data from each position by doing:dataArray(index, 0) or dataArray(index, 1)And when I want to get the two-position array I can use:
Dim posArray as variant posArray = dataArray(index)
I'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.
I have this recently converted application from vb6 to vb.net 2008. One of the errors stated is:'Point' is not a member of 'System. Windows. Forms. PictureBox'.I have searched and not found an alternative to this.Also, it says ReDim cannot change the number of dimensions in 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..
I have a string containing many lines. Each line has many values separated by commas. Basically it's in CSV format. The number of lines is variable but the number of columns is always 7.
I can get each line into a one dimensional array using Split(Var, Chr(10)).
I'd like to make it a two dimensional array where the second dimension contains each comma separated value.
I've got
Dim VarArray1() As String = Split(VarText, Chr(10)) Dim VaryArray2(0 To VarArray1.Length - 1, 0 To 6) As String
Is there a quick way to get the contents of VarArray1 into VarArray2. I know I can do the following.
For Counter = 0 to VarArray1.Length - 1 Dim line as string = VarArray1(Counter) Dim Values() as string = Split(line, ",") For Counter2 = 0 to 6 VarArray2(Counter,Counter2) = Values(Counter2) Next Counter2 Next Counter
But is there a quicker way to do it that doesn't require passing through each element of VarArray1 and then passing through each element of Values.
The eventual goal in all of this will be to find the highest value in the 3rd column (the arrays are strings at this point because not all columns are numeric). To do that once I get the values into VarArray2 I suspect I have to pass through each element VarArray2, i.e. VarArray2(Counter,2). Unless I can copy the whole third column into a SortedList?
i'm trying to tokenize my text but while doing that i'm facing a problem
would anyone like to solve it
Public Function lexemes(ByVal str As String, ByVal seps As String) As String Dim regexpression As String regexpression = Regex.Split(str, seps) Return regexpression End Function

I am trying to set a textbox text as the text I get from a web request, but I keep getting the error cannot be converted to 1-dimensional array of string.[code]...
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!
[Code] As you can see, the code in the client side calls a function in the Server that generates an array as output. And this output SHOULD be loaded into the new array that was created in the client side. The case is that it is not allowing me to do that. The blue underlined row gives me the following error: Value of type 'ClientTest.TestService.ArrayOfString' cannot be converted to '1-dimensional array of String'.
I cannot see what is wrong, the function generates the same output type as the new var that is expecting to load it. Why data cannot be 'converted'? And what would be the solution to turnaround this problem? PS: Actually my function is a bit more complex than that and evolves a DB query, etc, but I reduced its code to simplify as the problem is occurring just in the array transfer.
Error Message Operator '&' is not defined for types 'String' and '1-dimensional array of Byte'.
Complete Coding:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim fileSize As Integer Dim rawData() As Byte
But I get a runtime error that Operator '=' is not defined for types 'Object' and '1-dimensional array of DataRow' There should be an easy way to do this that doesn't involve creating new tables, etc.
i have a problem with my system.. i have try many time and i cannot solve the problem..here is my question
Use one dimensional array to solve the following problem: A company pays its salesperson on a commission basis. The salesperson receives RM200 per week, plus 9% of their gross sales for that week. For example, a salesperson who grosses RM5000 in sales in a week receives RM200 plus 9% of RM5000, or a total of RM650. Write a program (using an array of counters) that determines how many of the salesperson earned salaries in each of the following ranges (assumes that each salespersons salary is truncated to an integer amount):
A) RM200-RM299 B) RM300-RM399 C) RM400-RM499 D) RM500-RM599 E) RM600-RM699 F) RM700-RM799
i'm extremely confused. my professor gave us this as the FIRST problem to do in this intro to VB class...on page 380 of our text. use a one dimensional array to solve the following problem: a company pays its salespeople on a commission basis. the sales people receive $200/week, plus 9% of their gross sales for that week. for example, a salesperson who grosses $5,000 in sales in a week receives $200 plus 9% of $5,000, a total of $650. write an application (using an array of counters) that determines how many of the salespeople earned salaries in each of the following ranges (assuming that each salesperson's salary is truncated to an integer amount): $200-299, $300-399, $400-499, $500-599, $600-699, $700-799, $800-899, $900-999 and over $999.
Allow the user to enter the sales for each employee in a TextBox. The user clicks the Calculate Button to calculate the person's salary. when the user is done entering this information, clicking the Show Totals Button displays how many of the salespeople earned salaries in each of the above ranges.
I am using Visual Basic express edition 2008.I am trying to know if a value in a single dimensional array is repeated in the array. If yes, then multiply one of them by 100. For example:
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?
[edit]Sorry I left a bad title in this thread - confusing![/edit] Been a long time since I used an array - they are so limiting...But I need to build a simple string array - that I'm passing to a C/C++ function.
Is there any other way to do this other than keep REDIM PRESERVING??
Is it possible to have a two-dimensional array/list/collection such as the following. The first dimension is to have 2 elements, 0 and 1. The second dimension I would like to be able to have a different number of elements for each of the elements in the first dimension. To explain better, I'd like X in array (0, X) to go up to say 4 and Y in array(1, Y) to only go up to say 2.
So there would be: array(0,0) array(0,1) array(0,2) array(0,3) array(0,4) array(1,0) array(1,1) array(1,2) But no array(1,3) or array(1,4).
I'd also need to be able to use Redim Preserve to increase the size of the second dimension for each of the first dimension's elements.
I'm trying to display in a list box a two dimensional array using format string.The information for my array I'm getting from an external file.this is what I have, and I don't know how to fix this.
Sub DisplaySeatChart() Dim fmtstr As String = "{0, -15}{1,-15}{2,20}{3,-15}{4,-15}" For i = 0 To 9
I'm working on a program that generates random values for a byte array thats length is 16.I have already devised the generation method, but I want to use My.Settings to store this...but I haven't seem to have located Byte() for My.Settings.
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.
