create an XML file from a large Oracle dataset. The Oracle dataset contains an ID column and a bunch of different address types. For example, An ID will contain a primary address, secondary address, and a bill to address. Each of the three address types can have multiple addresses but I'm only retrieving the first three.Currently, I'm retrieving three of each address type then joining all of the data together. If I continue with this method, I would have to loop thru the dataset to find the ID and then loop thru the dataset again to find each address for each address type. This doesn't seem very efficient and I'm wondering if there is a better way to do this. Is there a better way to manage the data on the oracle side so that I can have one row for each ID? Or is there a better way to handle this on the .net side with collections and manipulating datasets?
Basically I have 4 empty textboxes. I need to calculate the total and averages of the numbers entered in them. So far, I've declared 4 variables and made it equal to the text that was input by the user. I'm stuck with the calculations tough. The user doesn't have to use all 4 boxes. So if he/she only entered 2 numbers, the total is divided by 2, not by 4 for the average. I think I'm supposed to use a for... next loop because the maximum iterations I should do is 4, but I'm not sure how to the code even if it is supposed to use a for loop. Otherwise, the rest of my project seems to work fine.
in my prev question i was suggested with LINQ solution. It was great and simple. I tried to solve next similar but a bit diff problem with similar approach but i failed.
how can i make the below code better

I've written a keydown event that needs to occur multiple times during the execution of a program, and it needs to play a sound each time. The first time the keydown event is triggered, the sound plays without a hitch. However, the second time (and all subsequent times) the keydown event is triggered, a system beep accompanies the sound. I'm using Studio Express '10 and I've already integrated e.SuppressKeyPress into my code:
I'm having a little trouble with this assignment for my 1341 Fundamentals class...A copy of the assignment can be found here. The section I'm having trouble with right now is as follows:

Add another TextBox and Button to your program window; label the TextBox side: and change the Text of the Button to Print hollow box. Write code to clear the ListBox and then print a hollow square box of asterisks with sides of length equal to the input number. For example, if the number entered is 10, the output should look like
I'm trying to create a program, which would loop trough all letters. I want for example show aaaa, then aaab to aaaz, then aaba and so on to zzzz. The problem is: how to allow user to enter the letter count? Here's my code with only 3 letters:
the purpose of the program is to display the monthly payments on the loan.My homework is to use do while loops instead of for loop.Here is the code for the for loop.
Option Explicit On Option Strict On Option Infer Off
[code].....
Now I'm having some trouble displaying the output using the do while loop, and I'm pretty sure it's a loop problem on my code. However, I cannot seemed to find out what's wrong. I looked at the examples of do while loop in my textbook, but I couldn't find anything useful to my problems of my program.This is the output for the do while loop.
Here's the do while loop code

When I use a For loop in a For loop the Contains Statement dosen't work! Even my custom one! I even tested mine and it works 100% And neither that or the String.Contains function work inside of For Loops And, I know both of them use loops to search through a string.
My function(It will atleast search once):
Function RealContains(ByVal load As String, ByVal needle As String) As Boolean load = load.ToLower
So I'm in the final stages of finishing a program I've been working on for nearly a year now, and this is basically my final hurdle. The Save dialogue is working beautifully, with 'flags' in order to switch it over from the regular input into text boxes to the Listbox input protocol.
However, I'm having a *** of a time getting it to take lines from the text file and put them in the proper text box. Here is an example file:
Quote:
SHOWNAME CALLNAME BREED
[Code]....
So with the sample file I provided above, in the textbox named callNameText would appear "SHOWNAME", and so on and so forth. With this build, I get a NullReferenceException on the "Me.Controls(strboxNames(i)).Text() = strAllText(ati)" line.
If I have a large number of classes, each similar to the other in certain aspects (they all share a common base class, but each does things differently), and I need to create Windows forms for each to allow easy changing of their values through a GUI? Create one matching form for each object in VS' forms designer, Or Use code to create the forms dynamically at runtime.
#2 makes the most sense to me, because a lot of these objects will share very common features of the form, notably "Ok" and "Cancel" buttons. But one object might need to draw a textbox on the form while another might need to draw a combobox. Not to mention, if I want to put icons on the "Ok" and "Cancel" buttons, I'd have to do this for each copy of the form in designer, and that sounds like it could get out of hand quickly.But is drawing forms through code sane? VS' forms designer is pretty sophisticated and designed to make life easier. Am I wise to consider ignoring its functionality and diving into the trench warfare of forms design through code? Or are there examples of automating form creation based on an existing object's properties?
I know how to create a file, but would it be possible to create multiple files? the number I would like to create is determined from the number in a textbox, i.e., if the textbox had 2 then I would create 2 files, if it had 5 then I would create 5 files.

I'm currently quite new to VB and am trying to create a multiple choice questionnaire for work. This is a depression survey in which there are 23 groups of statements with 4 options per group. Every time a patient clicks an option, the next set of 4 questions comes up on the screen.
I'm trying to convert the old VB4 code into the new VB 2010 code. Before we were using a control array and the code looks a little something like this[code]...

VB 2010 express. I have a situation where I want to create multiple list(of string), in a sub routine during run-time, where the list is available to other subs and functions in the same module, either to populate, edit or delete. The quantity of lists, names of the lists and their capacity will not be known until run-time. What would be the method and syntax for doing this?

which contains a combobox with two Gender options, Male and Female. When the form runs the user can select either male or female to perform a query. I made the ComboBox public and shared so that it can be viewed by other forms. On another form i added a ReportViewer and a dataset based on my database (MS Access 2007 database with 1 table named tblStudents). I don't have any problems when i try to run a simple query without parameters, but there is a problem with my

I've always had to use a program that does this stuff for me, but I'd like to just make my own program that does this. I've already got the individual bitmap images of the 3 sizes (16x16, 32x32 and 48x48) for the icon file and I usually find use some shareware program to create the icon file from the multiple bitmap images for me but I'm wondering if it's possible in .Net to create an icon file (*.ico) that contains multiple physical icons in it.
Okay so I've dug around all day and found that using multiple "background workers" would do what I would need for my application.How can I create 4 background workers and then feed the urls to the webrequest from a listbox? [code]
Okay, say I have a class named "ChannelList", and it raises an event named "FoundChannel"
But what I'M wanting to do is create multiple classes of different names that use that class, but I want to have all of the "FoundChannel" events be handled under one single sub routine?
First i am pretty new to coding and everything so yeah...I wish to make a distance and fuel calculator as my project. Included will be multiple combo boxes with different sets of information (The manufacturer of the vehicle, model of vehicle, the vehicles fuel use per 100Km, its transmission type, users choice of where they will depart from and arrive etc.) Is it possible to achieve this without using a lot of combo boxes? I've experimented using if statements for example:
if combobox1.selected item = "Holden" then combobox2.visible = true (it's bad i know)
Then from this they would choose their model type in another combo box and then choose their transmission type etc..I don't want to use this because then it will mean i will have to do it for each and every combo box for each and every different set of data because making one 'visible = true' i will have to make the other 'visible = false' and this will cause problems when i start adding a lot onto it.
