Xml Element Altering - Read And Change The One Field
May 13, 2010
I have some xml that I read from an xml document, now I need to take that same xml and then change one field and then drop back to a file again. [Code] so then as you can see I tried to use a new open of the document from scratch and I get the same error. I read that its because I may have 2 imports that have the same method? I had 2 XML imports and made it only this, but still get the same error. [Code] how to fix my issue or a better way to read and change the one field I need to change?

I'm trying to read an innerHTML string from an element on a webpage. I've loaded the page using the webbrowser browser class.
Here's the code in full
Imports System.Net
Imports System.IO
Imports System.Diagnostics
[Code]...
When I click button 1 for the first time I recieve the error "Object reference not set to an instance of an object." but when I click it the second time it returns the elements text perfectly.
I thought the wb.document element might not be instantiated so I've tried navigating to a page (google's homepage) before loading the page I want put with no success.
I also thought that maybe it wasn't giving the page time to load so I added the sub to deal with the documentCompleted event but this also returns nothing (though wb.document.url is set correctly to the webpage I want)

I am trying to read a comma delimited text file to an array, then change just one element in the array and write it back to the text file. An example of what the text file would look like is:
data1,data2,data3
data1,data2,data3
data1,data2,data3
I want to change data in the last line at the last postion , data3, for example. I am reading the file in with no problem. I am stuck on how to change the data and write it back to the text file.

I have an XML file, shown below:
Code:<?xml version="1.0" standalone="no"?><!--RISInsight server settings--><Configuration> <Server> <ConnectionMode>ServerName</ConnectionMode> <ServerName>(local
[CODE]...
The problem is that I want to read the complete XML file, however because I am repeating the same XMLElementName it only seems to read the first element, the code I am using is the following:
Code: Dim reader As Xml.XmlTextReader = New Xml.XmlTextReader(Application.StartupPath & "settings.ini") Do While (reader.Read()) Dim addToList As Boolean = False Select
[CODE]....
Is there a way that I can make it continue to read the XML file?

Calling OnPropertyChanged for an ObservableCollection only works when there has been some change to the properties of the collection, not the objects it contains (add, remove, clear, etc).
Is there any way to notify the View that there has been a change to an item within the collection?

If I want to change a single element of one of the elements of the array, for example the DayHi field of the 0th element, then the code ATRList(0).DayHi = 4 causes the error: Error3Expression is a value and therefore cannot be the target of an assignment. Now I could get round this by reading all the items out of the 0th element into newATR, changing the field I'm interested in and then doing a "ATRList(n) = newATR" but there must be an easier way?

I want to change the background color of an element when the mouseEnter event fires. How to make the color of the background darker?? I thought I can use an opacity mask, but it's a gradient, but I need it to be solid. Also it has to be in visual basic code, not in xaml.

visual studio 2010 - Altering array values in VB.NET
View 8 Replies
Oct 19, 2011
I'm trying to validate a form to be filled out by the users, and when the required section isn't filled, I increment an
ErrorCount += 1
variable to show that error(s) have occurred inside the program, I then also set an
ErrorArray()
to whatever the corresponding field number is, now I have 0-12 (13 fields). What I have also done is titled the labels that are associated with all of these fields to correspond with the ErrorArray() value that might be set, such as.
PatLabel0
PatLabel1 etc.
What I am trying to do is loop through the array contents, depending on which ErrorArray() values have been set, to go and set the corresponding fontcolor property of that label to red, to show that these now need to be filled out. This is what I have, but Visual Studio doesn't allow me to use the iteration through the loop as a reference to changing properties. Can anyone point me in the right direction to trying to figure this out, or at least tell me what else I could do. Just seems doing 20 if....then....else.... statements with 2 - 3 lines in each of them is redundant when 1 function line could do the same job. This is what I have.
for i = 0 to UBound(ErrorArray(12))
if(ErrorArray(i) = "*")then
PatLabel(i).forecolor = color.red
[code]....
that is basically all im looking for initially, but I can't do it.

I got a DataGrid Control that uses an Adodb.Recordset as a data source. I'd like to change the data type of the dodb.Recordset.Fields at run time. PS:I tried use the Type property but I got a message that it can't perform the operation when the object is open. Then I tried closing it with Close() but then it says the field is not available.

I have an Active Directory browser written in vb.net 2008 that allows an end user to visually browse AD. Currently it displays the full DN for each child and what I want is to display just the name of the OU. Something tells me I would use the Tag() function but after playing with it, I just couldn't figure it out. All I removed was our internal domain name.
Would someone like to review what I have now and offer some ideas on what I would change to alter how the tree is viewed while retaining funuctionality?

I'm using a 2D array to store data in a grid and all the data is ones and zeros. By default, the array is all zeros. When I attempt to modify values in the array using variable(y)(x) = 1 where x and y are integers in range it changes the value to 1 in the entire column, not just a single cell.

I'm trying to change the value of a field, and can't get it to work. I'm using the example they gave of how to read through a CSV file, looking and displaying each field. Everything works OK, and after I change the value it displays the new value, but when I look at the file I've created, it has the old value. I'm new to VB, so forgive me if it's something really dumb. Here's my code:

I have a number of rewrite rules for a lot of things that I did in IIS7, like removing trailing slashes, canonnical URLs, lowercase lettering, and such. IIS altered my web.config, and everything works fine on the website, like it should. But in the Visual Studio web.config, the opening < rewrite > statement is underlined in blue, and at the bottom of VS, it says that the element 'system.webServer' has invalid child element 'rewrite'. But this is how IIS made it. I didn't do this manually. Should I be concerned with this VS error, or should I just leave as be, since it's working how it should work?

Is there a way to alter the from field? I'd like to have everything coming from MyProgram for example, even if that user doesn't exist in the Lotus directory.[code]...
