View 3 RepliesI have the array dimensioned as public to the form. I populate the array on Form1_Load.When I click the button btnReversingAnArray the first time all are sorted in reverse except for Wendy and it is the last item shown. ie..(The book I am even shows an image of the list Box and their example also shows Wendy as the last item)
Richard
Michelle
Jay
Harriet
Wendy
Then I do nothing else except I click the button btnReversingAnArray again and then it displays correctly.

View 3 RepliesI'm in a pickle... either that or it's getting too late in the day. How do I loop through an array in reverse without using FOR?I have an array of string values, I need to loop through these values until I find the first instance of a value then stop. I have considered a sort on the array but each query would need me to sort it accordingly (the data in the array has many instances of the strings within strings I am looking for, e.g. there could be several 'to' but I need the first, there could be several 'from' but i need the last)When I find the instance of the string, I then need to grab specific data from that string.

I just want to know if we can reverse an integer number without using an array
View 3 RepliesI hope that I'm not just overlooking something, but I am really struggling with working with an array. To simplify my issue: Suppose you type out the values: 1 through 5 into a textbox (1 2 3 4 5). I'm looking to convert that string to an array, so that I can reverse the order and then show the new order in the textbox.

have the structures are populated and when the form opens up, I make a copy of the structure.on my form i have a textbox... that would have information matching the TagName(x).TagValue I am trying to figure out how i could find that value in my textbox quicker than doing a loop through the tagname structure.
I wanted to simply on click a button to add those newly created textboxes to an array of textboxes. Starting with those labeled "Address". But I am finding this very difficult. I am able to add those originally on the form into the array very easily. But am unable to add the newly created textboxes into the array.
Here is my code so far below.

View 2 RepliesI have a lot of control array textboxes called txt(1) to txt(320) on form2. I have a textbox1 on form1 with a click evet that says textbox1.text= form2.txt(1).text but it gives an error (txt is not a member of form2). I tried disabling option explicit, option strick and option infer. Still won't work. My code is to long for this place maybe a short version osf the code. Do I need to make a Public MyArray(15,15,15,15) as string, in the Module1 then copy txt(n).text to the array or is there a way to access txt(n).

This is hopefully a softball syntax question: I need to call a method with an empty Object array for evaluation and set initial state. In C# I would just do this:
func(new Object[]{});
In VB.NET I am forced to do this:
Dim ctrls() As Control = {}
func(ctrls)
Is there a way to shorthand the call in VB.NET and have everything happen in one line of code?

I have been learning about OOP and classes from a book and one of the question is the book has asked to create a simple Saving/Checking accounts Program. The question says that most of the functionality must be done through an Accounts Class, and this Acoounts class must inherit certain private fileds from an base class 'Transaction.
The question also says that data from the Saving/Checking accounts Program must be read to and from a text file, and these functions must be done within the Acounts class.
i have done everything the question asks to the best of my knowlegde and understanding but when it comes to storing and retieving data from the textfile i cannot utilise the array i created to store the textfile data onto it.
Bank Account.Write a program to maintain a person's Savings and Checking accounts. The program should keep track of and display the balances in both accounts, and maintain a list of transactions (deposits, withdrawals, fund transfers, and check clearings) separately for each account. The two lists of transactions should be stored in sequential files so that they will persist between program sessions.
Consider the form in Figure 11.12. The two dropdown combo boxes should each contain the items Checking and Savings. Each of the four group boxes corresponds to a type of transaction. (When Savings is selected in the Account combo box, the Check group box should disappear.) The user makes a transaction by typing data into the text boxes of a group box and pressing the button. The items appearing in the Transactions list box should correspond to the type of account that has been selected. The caption of the second label in the Transfer group box should toggle between "to Checking" and "to Savings" depending on the item selected in the "Transfer from" combo box. If a transaction cannot be carried out, a message (such as "Insufficient funds") should be displayed.
The program should use two classes, Transaction and Account. The class Transaction should have properties for transaction name, amount, date, and whether it is a credit (deposit) or debit (withdrawal/check). The class Account, which will have both a checking account and a savings account as instances, should use an array of Transaction objects. In addition, it should have properties for name (Checking or Savings) and balance. It should have methods to carry out a transaction (if possible), to display the list of transactions, and to load and retrieve the set of transactions into or from a sequential file. The events InsufficientFunds and TransactionCommitted should be triggered at appropriate times.
Hint: In order for an Account object to display a list of transactions, a list box should be passed to a method as an argument. The method might be declared with Sub EnumerateTransactions(ByVal lb As ListBox).
Here is my code. I am sorry this code is basic and unedited.

I have problems with array of structures.my structures are like this
structure order
xxxxxxxxxxx
yyyyyyyyyy
zzzzzzzzzzz
end structure
and then I created many array of structures, like this private arrayorder (100) as order
now i need to sort the entire xxxxxx member of the array of the structure with a function, but I dont want to use loops with arrays indexes to access the information. I want to know if there is another method to reference the array and the member of the structure to get the data.
why the next example throws a System.ArrayTypeMismatchException?New Int16(){4,5,6}.Cast(of UInt16).ToArray()I expected that this line returned a UInt16 array containing 4,5 and 6.

I'm creating a program which you can fill in a number of boxes and then send it as an email. I would like to know if there is a way to create some form of array out of all my textboxes so that i can save time on the email.For example,
For i = 1
EmailCont = TextBox(i).Text

These are the directions for the assignment.So far I am able to get the file read and printed onto a list box.The book we have for the class does not clearly talk about using the array of structure method with formatting an imported text file.After that I'm pretty much having a bit of trouble with everything else.I know I can figure most of it out but what I'm having a big amount of trouble with is the array of structures that he wants.I know that when I have the file imported that I need to save it temporarily and go through it and at every ":" put it in an array and save that spot and then keep scanning through the file. I know it is going to be a for loop using the index to count through but I'm not sure if how to start it.This is how the text file that he wants sorted out looks.
