writing to an xml file. I am using code i got from a faq off this site which works great with the exception being it does not allow you to append records to the file. it over writes the original record.

I have used the FileStream class with the XmlTextWriter in the past without issue but here I'm using the XmlReader from a WebResponse. I need to the complete contente of the XmlReader dumped into a file. I have the file setup as a streamWriter but I just can't seem to get the content of the XmlReader to the file. I just keep getting a 0KB file.
If FirstDataHttpRequest.HaveResponse = True Then
'Put the response into a stream so that we can create a reader

I am trying to parse this xml file, which has some nested nodes. I don't know how to put the xml file content that looks neat here. if you can tell me how, that would be great too.And this is my code. I am able to retrieve some info, but some of them is not correct (strGrant has values that is supposed to be for strSupport).
Dim strGrant, strSupport, strDatabank, strWeight, strNumOfGrants, strNumOfSupports, strNumOfDatabanks As String
While XmlReader.Read()
Console.WriteLine("{0}: {1}", XmlReader.NodeType.ToString(), XmlReader.Name)

Pretty much the only thing I have changed is created a loop because I have one xmlstring and want to break it up and create tif files from it(which it actually does do).My problem is this: readbytes inside the while loop throws an exception at the last time through the loop that says I have an "unexpected end of file; the following elements are not closed" and lists them
[code]...
So there are tags left open after the readtofollowing("image"). I tried catching the exception to no avail, tried to read until eof, no avail. I dont really need elements to be closed, I just need to continue because I created files using whats in the image tag.EDIT: I think my xmlstring is going to have times where it will be too big to do a parse without slowing down too much.../parsing binary data?
I'm using to code below to write and read an xml file. Writing works fine, but I get an error message on the"XMLReader.ReadEndElement()" line when an element is empty.'Element' is an invalid XmlNodeType. Line 4, position 6.XMLReader.IsEmptyElement is probably what I should use, but after reading the documentation, looking at an example and playing around with it for a while, I'm still not sure how to use it. No matter what I try, it still keeps showing an error on that line. This is the xml file.
<?xml version="1.0" encoding="utf-8"?>
<Data>
<Storage />
<Time>08:30</Time>

I have the following code that adds the elements from between the <movie></movie> elements to a listview box.Private Sub ParseMovie(ByVal reader As XmlReader)
[Code]...
What I would like to do is make sure that it reads everything instead of using ReadToFollowing. I might add something else to the xml file, such as <release_date></release_date> and I want to make sure I don't have to edit the ParseMovie sub routine. I looked at the members of XmlReader, but I can't seem to get the right methods to do this efficiently. How should I parse every element between <movie></movie>.

I have just recently been using VB 2010 after using VB5. I have noticed a lot of changes. The problem I have is that I wish to open and save text files to and from arrays in the background. I've attached what I would do in VB5. I have searched around, but all the examples I find use a Textbox instead of an array. Can anyone show me how I can do this with VB 2010?

I am attempting to gather a group of file names from a directory. I am able to do this. I tested the code by having the list populate into a listbox and all desired items were added to the list.
Here is my code:
Dim di As New IO.DirectoryInfo(strPath)
Dim dir1 As IO.FileInfo() = di.GetFiles("*.txt")
Dim dFiles As IO.FileInfo
ListBox.Items.Add(dFiles)
However, a listbox is not my desired output. I am attempting to write these file names to a text file for purposes of then parsing the information to a datatable to compare with another datatable. How to get my filenames written to a textfile.
I am working on a program using VB.Net 2010 which will enable me to setup groups of files & folders for back up with syncing capabilities etc. I have a concept program which is based on some sample code I found out in one of the VB.Net forums. I have modified it from a command line based program to a form based program. At the moment I consider this code to be a "concept" program which once I have the various copy/sync routines developed and debugged will be integrated in to another program I wrote for
creating "Back Up" groups to automate the process. There are some 3rd party programs that do similar things that I want to do such as Microsofts Sync Toy, but none of them offer the grouping and exclusions options that I am going to program in to this backup/sync program.
So here is my problem, I have the included code taking two folders, a source and a destination, and copying everything from the source to the destination. It will skip over any unchanged files/folders and will delete anything found in the destination folder that is not found in the source folder and it will update all files in the destination folder that have a newer version in the source folder. In other words it will mirror image the source to the destination but will be smart enough not to copy unchanged items from the source to the destination thereby saving a lot of time. The sync part of the program is working fine, the displaying of the progress and results is not.

I have a structure in memory which is working fine - now I need to write this entire structure to a file.The below code almost compiles, the problem is that "mstaRecordInfo" cannot be changed to a string, probably because of the Date field.

for a school project I have to write data from a listbox to a new file that a user can create. I can create and save a file no problem, but for some reason I can't write anything. I followed the textbook provided but when the file saves, I open it up and it is blank. I'm using fileWriter.WriteLine and I'm just test something basic to write to a file first and I can't do it:
Code:
Private Sub storeFileButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles storeFileButton.Click
'creates a new file
Dim result As DialogResult ' stores the file
Dim fileName As String ' name the file to save the data

Well I'm in the middle of making a program to edit .ini files. Although I have hit a snag. I can save my settings (relies off checkboxes) with ease, however if I change something and/or hit the save button again even after the code has finished, both my entire .ini files are cleared (filePath and filePathPrefs) and all text is gone. Here's my
