LINQ: Writing And Reading XML Settings?
Mar 8, 2012
i am having trouble reading my XML settings. I Create new entries like this
Private Sub Create()
Dim doc As New XDocument
If File.Exists("Settings.xml") Then
doc = XDocument.Load("Settings.xml")
[code]....
The XML file will have multiple <Network> Entrys. I cant figure out how to loop the file and get every <Server> entry. But then if i opened a form and gave the variable one of the server entries how could i get that <Network> based on the server entries child parameters.

I'd like to know if there's a better way to read/write various user settings to disk. My program loads up a bunch of settings during load but also during execution from a few different forms, encrypted string values, boolean values, different types. The code seems to work okay but I have a feeling it's just not the best way to be doing this. Some of the settings are encrypted strings that have to be decrypted/encrypted so the code to read/write the text file is a bit different on some items. The data read from disk usually goes to a public string, a textbox, or a up/down type control. Below is about 1/10th of the settings that get loaded/written at various times. Anyone have a better way that might be more efficient that I should look at?

is this a good idea or not really? instead of having to open a file through filestream, i would like to just save text in an encrypted format in application settings. is this OK if the text is under 10mb? what would be the best way of implementing this?

Just playing about with LinqToXml and I need to form a xelement as follows:
Dim xe As XElement = _
<Xml>
<ElementOne>
<SubElement></SubElement>
<SubElement></SubElement>
[Code]...
This creates an error here: xsi:type "XML namespace prefix 'xsi' is not defined"
Is it possible to write this in Linq to xml?

I'm creating a simple forms application where users can enter their details and save the information to a .ini file because I needed this for a simple game profile. I've tried to make it write "Name =" + txtname.Text but it won't work anymore. And as well as that, I don't think It will load the text back from the ini file.
Here's the code I used;
Public Class Form1
Dim hFile As Long
Dim sFilename As String
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
[Code] .....
Form designer: [URL]
Form1.resk: [URL]
Form1.vb: [URL]

I need to read a value (and possibly adjust the value) in HKLMSoftwareMicrosoftWindowsCurrentVersionUninstall key on both 32 and 64 bit systems.I've tried accessing 'stuff' by compiling my widget as both a 32 and 64 bit app, but nothing is working. Then I came across some information indicating that this could be done from a 32 bit applicaiton using KEY_WOW64_64KEY [URL] somehow, but I can't figure it out.
1) Check the existing value of HKLMSoftwareMicrosoftWindowsCurrentVersionUninstall{ProductGUID}DisplayVersion handling both architectures.
2) If the value <> "" And <> Our Current Version Then
3) Write the Current Version to the value mentioned in step 1.
I wouldn't think this is that difficult as I've worked with registry before, but the 64 bit stuff is throwing me for a loop.It would be nice if I could compile my app to target AnyCPU then detect where its running on 32 or 64 bit. The app could then look and update in the appropriate location.I currently am set to use .NET 2.0, but could go to 4.0 if there is something in there that makes the above tasks easier.

I have created a small game for my son and after each game it tells him his score.all I want is to write the highscore to a file and have it open each time he begins a game..so he can see what his last score was. I dabbled with all this Io.file stuff and I just can not seem to get it to write to the file..also how do I work with app path in this case? I mean when the game is done and installed the current path of the save text would change.

seeing as '.dat' files contain only what you want them to and there is no preset encryption for them etc could I write data to one by using this simple process:
1) Change file extension to '.txt'
2) Decrypt
3) Write
4) Encrypt
5) Change file extension to '.dat'
and pretty much the same for reading it. or am I thinking to simply?
I thought of the above way as i know how to write to text files already, but is this the best way to do it? or is there a better way?
EDIT: Nevermind you just write to it like a text file and encrypt/decrypt it. request lock/delete from mod.

I am trying to create a bunch of records, there will be a limited number of "Codes", about 50. Each "Code" is associated with a name from a textbox, I was trying to have it save each one when you click a button, to a .txt file.So, from the start the record will be blank, the person will go through the form, choose a number from a numerical up and down box, pick a name associated with it (both of these are mandatory and not implied). When they click the button, it will save the contents I talked about into a .txt file, say the number is #2, and the name is "Bob", the next time they try to change that value for #2, it will overwrite "Bob".

I'm trying to write a program that will read a text file, and sort of filter out some things into some new files for myself. I have a website that I like to put information such as Artists, and songs for music. My website writes the Artist, and Song I input to one file on a new line in the format of (Artist - Song). The problem is it's gotten massive! I want to start organizing my artists, and songs anyway I come up with but I don't even know where to begin. To narrow it down I want to go into the file grab the artists name before the (-) and then write it to one file. After that I want to write everything after the (-) which is the songs to a different file. What file reading, and writing method should I use? As you might be able to tell I'm quite the noob.
