I'm using Visual Studio 2008.I've recently begun toying with XML, because I have been using XLS up to this point. I want my apps to be more flexible.
OBJECTS:
Label1
Button1
Profile.xml (ok, not really an object, but you know ...)
GOAL: To display the Sum of <Calories> in Label1.Text when Button1 is clicked.
Here is the XML file (Profile.xml):
<?xml version="1.0" encoding="utf-8"?>
<Days>
<Date>[code].....
I created a method and pass the element type, id, and any inner text that instantiates a new html element. The last statement: Me.Controls.Add(element) adds it to the end of the page, but I would like it to be inserted in a specific position (between 2 divs within a form). What I am describing is very similar to this post on SO here, although it was for javascript.

I am trying to add the values in my array.. and this is my code
dim totals(6) as decimal
public function AddIBNRTotal(byval Amt as decimal,srvcdesc as string) as decimal
if srvcdesc = "ZZ_TOTAL" then
[Code]....
I know the addIBNRfunction works fine cause it is displaying the correct amounts in my textbox
but when i call the Sumnumber() i am getting 70000 dollars short...
So is this the right way to add values or elements to a array...
<data>

<id>1</id>

i would like to get the unique catlogs, so from this list i want to extract only 7190, 7192, and 7193. i have a script that puts it into a dropdownlist by using:

DropDownList1.DataBind()
but i need it to get only the unique values.
I have the following piece of XML:

I have been learning VB.NET and am currently having troubles retrieving data from an XML file. I'm trying to keep the code as simple as possible as I only need to select single items from an XML file, not rows of data.
The XML file contains:
<CurrentPeakUsage xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://au.com.amnet.memberutils/">
<Period>

While the msgbox will contain the entire XML document, so it is loading correctly, I can't pull the single element value.
How would you code this so that it adds up the first column, and then the second column?
Dim intSales(,) As Integer = {{100000, 150000}, _
{90000, 120000}, _
{75000, 210000}, _

View 2 RepliesI've managed to get my CSV file opened and the individual elements of each line read into an array. I've also managed to count and list the number of elements in the first row (i.e. the column headers).
[code]...
listOfNewFileRecords.Add(currentRow)' ADD EACH RECORD TO THE LIST AS THE FILE IS BEING READ Now the next stage is to access various cells within the whole opened file, so that I can condition/modify the text.So does 'ListOfNewFileRecords' have a way/method of accessing a particular element, in each record of the 'List'? I've tried using the intellisense, but can't make enough sense out of it to get anything to work.

I am just starting VB at 60 years old and with no programming experience and nobody to ask for help...except here, of course. So needless to say I am hitting brickwalls. I am using "Murach's Visual Basic 2008" and it seems to be a good book. This is what I am up to I have to declare an array with 5 elements with an index. I think that part is OK. Then add code that adds each element to the next one every time a user clicks a button. I have had many tries but the best I can get is just the grand total of the elements. Here is the code I came up with:-

Is anyone able to show me how the button click would reveal a progressive total of the elements each time a user clicked on it? It would be good if the book came with answers or had a forum for their readers.
I want to copy the elements from one list to another.

tell me an efficient method of retrieving the CSS between tags on a page of markup in .NET?I've come up with a method which uses recursion, Split() and CompareTo() but is really long-winded, and I feel sure that there must be a far shorter (and more clever) method of doing the same.it is possible to have more than one element on a page, and that the element can be either or .
View 3 RepliesHow is it possible to take an XML document and in .Net scramble all text elements to make them un-readable to a human?
[Code]....
We only need scrambling not encryption, i.e. not human readable at a glance. It doesnt matter if the user could de-code it with 30 seconds effort. We dont know the schema of the XML, so all text elements must be located in code. We need to de-scramble the XML later how one would do that too. It needs to be simple, e.g. no pre-sharing keys, certificates, etc. Only the text elements should be scrambled - not the nodes, attributes, etc.
is there a formula for this? for example how many elements would be in this?dim m3array(5,4,1) as integer
View 4 RepliesI don't get it. If I want to change the text on a button from a thread other than the UI thread in Visual Basic .NET, I need to use a delegate, and do something along the lines of

Button1.Text = TheText
End Sub

Of course I can make more generic functions that aren't so hard-wired. But still, it seems like a lot of typing. Am I doing this in a roundabout way? How is this not included in the control properties?
