Looping Through Loops In XML?

Mar 24, 2010

This is for .net frameworke 3.5 and visual studio 2008 in VB.Net.Two things we would like to do: 1) loop repeating node blocks 2) loop (through repeating node blocks) within repeating node block loop
First thing:

How do you loop through an xml that has repeating node block (<STRUS name="1000A") and extract the following node? For example you want to extract the IdentificationCode in the node that has <SVALU name="ZRT" and is from pos="9".So, the following example has the IdentificationCodes (TGJ23, PGA12, TPX12)

<?xml version="1.0" encoding="UTF-8"?>
<DocSplitterReport xmlns:xsi="http://www.w3.org/2001/X .......
<STRUS name="ROOT" lineStart="-1" lineEnd="-1">
<STRUS name="TAC" lineStart="1" lineEnd="194">
<SVALUs>

Monthly Payment Calculation, For Loops To Do While Loops?

Oct 8, 2011

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

Option Explicit On
Option Strict On
Option Infer Off

Contain Functions(They All Have For Loops) Don't Work In For Loops?

Mar 6, 2011

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

I have a 5 by 5 matrix I want to populate and I would like to simplify this into for loops. As I understand, I would need 2 for loops to complete this task?

Dim x(4, 4) As Char
x(0, 0) = Mid(key, 1, 1)
x(0, 1) = Mid(key, 2, 1)
x(0, 2) = Mid(key, 3, 1)

Doing Loops In .net Using Regexs?

Mar 30, 2012

I'm writing a super small interpreter in vb.net because i need to execute a simple (invented) language so the app understand it and do what ever it needs to do.Everything went well until i reached the control structures and the loops.So my question its, in a code that its executed line by line using a simple for each how can i match the "WHILE ;" AND "ENDWHILE;" and execute the code within it?

The first thing that came to my mind its kind of flag the line of the reader and read the content from that line until find "ENDWHILE;" and the store that to execute late, so keep isolating the code in parts until I've all parts and then execute it.But i'm not so sure how to code it or if my reasoning its correct.PD: I'm using regexs.

Using Names In Loops?

Sep 30, 2011

Im somewhat new to VB, my first time writing a mildly long program... have a program that will create an unknown number of textboxes, then later I will need it to manipulate those textboxes. I set it up so it names them txt1, txt2, txt3 etc..How can I write a loop that will refer to each of these textboxes by name so I can do what I need with them, ie for example in

For i =1 to x
txti.text = i
next

this would make no sense...how do i write the names correctly so the computer can understate and loop them as txt1, txt2,...?

Calculating From Multiple Txt Using Loops?

Oct 17, 2011

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.

For Next Loops Displaying Incorrect Value?

Feb 2, 2012

The Code has two options. Option one starts with 1 dollar and doubles everyday for 10 days. If this is correct the value should be $1024 but instead it shows double that ($2046)

The second option starts with $100 and adds $100 per day for 10 days. The number should come out to an even $1000 but instead shows $6500

How To Reference Arrays Via Loops

May 21, 2009

I have 5 arrays named array1 array2 array3 array4 array5. Each array has 5 elements. I want to access each element in each loop via a for next loop the pseudo code would be something like this.

for i = 1 to 5 / this loop calls the individual arrays
for j = 0 to 4/ this loop calls the elements in each array
array (i,j) /do some action on the element here
next j
next i

But as it stands, there is no array called simply array, and I can't figure out how to append the i counter to the word array and thus achieve what I want.
The alternative is to have 5 separate loops, one for each array but I feel sure there must be a better way.

Multiple Loops To Create XML?

May 22, 2009

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?

Nested Recordset Loops In ADO.NET?

How do you do nested recordset loops in ADO.NET? In ADO, you could just open one firehose cursor for the outer loop and a static, client-side, read-only cursor for the inner loop and nest the loops. But you can only open one DataReader at a time and Datasets aren't read-only.
