I am attempting to reverse the numbers in the array I have below. I was able to set the numbers from 1 - 10, but now I am unable to get the array to work properly when trying to reverse, I keep getting an error "Value of type 'Integer' cannot be converted to 'System.Array'.

So for an intro to programming class, we use visual basic, and i have to write a program that reverses the characters in a string. I've written a code that (i think) turns the string into an array, and then used the array.reverse method to reverse the characters.
I feel like my code is correct, but clearly it is not....when i run the program, there are no bugs, but instead of giving me any part of the input string, it returns "System.Char"
I'm a TOTAL beginner, and clearly not very good at this sort of thing, but here's my code for my "reverse" button:
CODE:
I'm open to other methods for reversing strings, but I'd like to stick with this one if at all possible...
Im looking to dynamically populate a Placeholder with data sent from a textbox on the same page, but in reverse order i.e. the latest post goes to the top ratehr than the bottom - kidda like Twitter or Facebook.The code I have so far is below but I keep geeting an error stating that "BC30311: Value of type 'System.Collections.ArrayList' cannot be converted to 'System.Array'." [code]
I was wondering how it is possible to reverse a TreeNodeCollection. Since it doesn't have an inline reverse function, I've tried several other methods to no avail: everything from copying the nodes into an array (which has a built-in reverse function), reversing it, and then copying it back into the TreeNodeCollection to using a custom reversing algorithm. Nothing has succeeded.
[Code]...
Any ideas as to why, or how, additional nodes are being added? It doesn't make sense to me as to why that would happen. All I'm doing is changing the values of nodes that already currently exist.Edit: In addition to this method, another possible way to approach it would be to sort the treeview in reverse order in the first place (I think by using an ICollection, or possibly IComparer?), but I've no idea how to accomplish this. I'm not even sure where to start regarding using an ICollection to sort the nodes in a custom fashion.
I'm creating this program where the user inputs their name in this one textbox, and they click on the button where it should come up with their name in reverse(Last Name, First Name) in a message box. My message box doesn't work. My code does show I'm using the If statement because I'm trying my make sure the user is inputting letters only and nothing else. But I would fix that later thats not my biggest concerns. [Code]
I have written a simple VB.net application which saves information to an RFID tag. I am now trying to compress my data. The solution I have come up with involves bitwire operation.Basically I store 2 numbers per 1 byte (0-9, 10 being a period, 12 possibly being a negative/positive flag,13,14,15 unused as of yet).The code I am using basically shifts the byte containing a number left, 4 spaces, then 'OR's it against another number.Therefore 12 is now represented as 00010010. The problem i'm having is decompressing. Obviously getting the '1' back is easy, as I just shift right 4, then grab it. I need to append or remove the last 4 bits.My solution after many headaches was to reverse the bit order, shift left 4, then reverse, then tostring it.
n my project i am to enter a name and a test mark into two separate text boxes and then select the button to store the information into the arrays, one array for names and another for marks, but when it is reset using the Erase <Array> fuction andi try to re enter information, no matter what information is entered i get a "Null Reference Exception Unhandled" Error.I am using Visual Basic 2008.My code is as it says from now:
Public Class frmAdverageTestMarkCalculator Dim ClosingMsg As String Dim Closingtitle As String
I'm having trouble assigning values to an array and am getting the error, "Value of type MemberFocal.Member cannot be converted to System.Array" - MemberFocal.Member is part of a custom class and I am attempting to create an array of these objects. Here is the code:
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'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 have been assigned to Convert a VB.NET project to C# and I got stuck. I am using a class called RsiOPCAuto, but I don't think that I'll have to go into to much detail into explaining how it works. Let's just get on with my issue.
So basicly what i do is grabbing an object from my class using this code:
public partial class FrmPartialMain : Form { RsiOPCAuto.OPCServer oOpcServer;
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]...
I have to copy a List of Books given below to a Multiline TextBox and then parse the BookName and Version to be stored in a varaiable called _BookName and _Version which i will use to store it in a database later. When a Line is successfully read i want to delete that particular line from the Multiline TextBox but i am getting "Index out of array exception".
BookName: Design Analysis, Version: 18 BookName: Metals and Non Metals, Version: 12 BookName: Surface Diagram, Version: 10 BookName: Elements and Compounds, Version: 10
I have the following code below which has an error. When the checkbox is set to true and for example change the "role", and click save the following error is given;"Index was outside the bonds of the array". The TxtPayCont is a concatenation of title, fname, and lname in an array. Therefore, if all the fields have values, then it works fine. So if it is Mr Jones Tim, this works, but, if it is Mr Jones it doesnt not. It has to have 2 spaces to work.
If chkPayCont.Checked = True Then Try '* Function to split the Contact Name Dim PayCont As String() = Regex.Split(TxtPayCont.Text, " ")
I have an error index is outside array bound with this code: Private Sub btnSearch_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSearch.Click Dim record = (From line In IO.File.ReadAllLines("test.txt") _ Let fields = line.Split(","c) _ Select New With { _ .drawer = fields(0), _ .number = fields(1), _ .title = fields(2) _ }).Where(Function(r) r.title = TextBox3.Text).FirstOrDefault End Sub
