Here's a portion of my xml file
<sources><comicbooks><source>
<profile>0</profile>
<name>Main</name>
<path>*mypath not showing*</path>

I am also using a schema file for the sources.xml file.
Here's my
Dim fileSources As IO.File
If fileSources.Exists(filePath & "sources.xml") Then
Try
Dim Sources As XDocument = XDocument.Load(filePath & "sources.xml")
[Code] .....
lbSources doesn't get populated with anything and Label2 doesn't change either.
I have a user defined structure in a list that I am trying to change the value for in an individual element within the list of structures. Accessing the element is not a problem. However, the compiler complains
"Expression is a value and therefore cannot be the target of the assignment"when I try to update the value.For example:
Public Structure Person
Dim first as String
Dim last as String
Dim age as Integer

How to get values for array elements in VB.nET from the user.also i wanted to display these values in the combo box.[this is easy i could manage this].

View 1 RepliesI am new in programming. And I am coding with VB.Net (VB2008). On my form I have 9 checkboxes. And each of this checkbox when checked is meant to submit a value to a dynamic array. Initially the array was a constant that was declared like these:
Dim Notes() AS integer = {1, 2, 5, 10, 20, 50, 100, 200, 500, 1000}
But I want the array to be dynamic. That is the user of the program is to enter the element of the array. So I decided to use checkboxes. So that if the user of the program checks any of the checkboxes, a particular value or element should be submitted into the array. And the user should be able to check as many checkboxes and have values representing those checkboxes submitted in to the array.
For example: if the user check checkbox1, checkbox2 and checkbox50.
The array should look like these. { 1, 2, 50 }
or if the user check checkbox1000, checkbox200, checkbox10 and checkbox500
Then the array should hold or contain the following integers in this order; {20, 200, 500, 1000}.
That is the array is dynamic and the content/elements of the array and the bound of the array should depend on the checkboxes that is checked. What other means can I used to enter values/elements into a dynamic array during run time.
I'm trying to read the XML I generated. Here's my writing code:
'XML EXPORTATION BEGIN
'Create the file
Dim myXmlTextWriter As XmlTextWriter = New XmlTextWriter("C:Simple TimerProfiles" + timer_name + ".xml", System.Text.Encoding.UTF8)
'Choose Formatting
myXmlTextWriter.Formatting = System.Xml.Formatting.Indented

I want to make an application that takes values & innerhtml from some elements on a webpage i made. For that i added a webbrowser to the project, and pointed it to navigate to my localhost server where i have some pages. However when i use the document.getelementbyid i don't get nothing on my richtextbox, and i don't know why, i use this function lot in javascript & i think its quite similar, so i don't know why it doesn't work , here is the code i use.

I wish to read a web page that had various frames and div elements.To start with I would like to create a routine that justs lists all of those elements values and then display each element name and its value so I know what I have and how to reference it later on.I have been using the WebBrowser control and have managed to do a few basic things so far like go to a website and auto login.
View 2 RepliesI 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.
View 1 RepliesI have imported a number of web elements that are called "reference values" from a website. These are added to the end of a website to navigate to a corresponding page. I am going to go to said website individually for each "reference value" and scrape code for use in a scheduling programming. How should i navigate to each of these websites when the url cannot be edited. The "reference values" are currently stored in an array but this does not seem like the correct method.
View 1 RepliesI feel quite silly asking this, but I couldn't find a definite answer anywhere. in vb.net, how are the array elements defined (if they are defined) for, for example:
Dim myarray(5) as int
does, at this point in time, myarray(3) for example have a defined value? If so, what is it?
Dim Document = XDocument.Load(FileName)
Dim findElement = Document.Elements("GradeProfile")

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.

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

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...

View 4 RepliesI 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}, _

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.
