I have created a string that holds the xml information that I need. I want to go through the xml in that string to go through each of the elements. I know how to do this if it is in a file like (books.xml) but how can you read it from a string?

I pretty much understood how to write text to a file, but I cannot grasp how to READ the information. After I read the information, I would like to add each seperate line to a ListBox. Each line in the text file is a file path for a music file, as the file I wish to read information from is a "custom extension" playlist file. I know what to do after I get the file path, but I do not know how to get the file path from the playlist.
I'm working on a way to authenticate users in my app, and what I've come up with is the following method.To write to a database, the user must have an account in SQL server 2008. However, I still want people to be able to view the application if they don't have access, but only read, they can't sync any changes. This is working well, as I have a string array hard coded containing approved users:
Dim Users() As String = {"BWANG", "EDASALLA", "ERICHARDSON", "HALONZO", "JCHAPMAN", "SKIM", "PMACK"}
The one problem with hardcoding is that if I need to ever add a user later on, I'd have to release an update to the program. (which isn't hard as I already have updating built into the app, and users can still download updates even if they can't sync.)
What I'd like to do, is use an encrypted .dat file that contains the user names, and store that with the application, so that i could always be added to, and only one file would need to be downloaded.
I have code in place to encrpt and decrypt the .dat file (called users.dat) and this code works for single text entries in the file. I need to figure out how to load a list however into the array in place.
Imports System
Imports System.IO
Dim userfile as String = "C:users.dat"
Dim Users() As String = Data.Decrypt(File.ReadAllLines(path))
Basically each line in the file will have an encrypted user name, and i want it to decrypt each line and store it back into that authorized user list.
I have made this code and it does work with a normal string key, but with a multi-string value(REG_MULTI_SZ) key it does not.[code]The error is this : Conversion from type 'String()' to type 'String' is not valid.So how do i read from a multi-tring value registry key and list is all into the listbox ?

View 2 RepliesI need to parse a string with time info from one timezone and output as another string with the time info for another timezone.
ex. "19880311 23:44:35 Moscow" > "yyyyMMdd HH:mm:ss NewYork"
it must observe DST, parse the input with format string and allow output to be formatted with a formatting string the city names are not important and can be replaced with f.ex. timezone codes
I've built a string using the Format method:
Format("[{0}{1} {3}:{4}]", var1.ToString, var2.ToString, var3.ToString, var4.ToString)
var1 to var4 are long type. Is there a way to easily extract the information back (other then the String.Split method) ?
Like: MagicMethod("[{0}{1} {3}:{4}]", formatedString, var1, var2, var3, var4)?
I have:
1 ComboBox(cboCultureInfoNumeric) with the required CultureInfo.
1 Textbox(txtNumeric)
1 Label(Label1)
When the user change the Culture info the decimal point or comma change in the textbox(txtNumeric) nicely.What i try is to change also the text in Label1 by the culture info.If the user change the CultureInfo to German the Label1.text = �German�If the user change the CultureInfo to Spanish the Label1.text = �Spanish� And so on�
What I have do is :
1 - Set the Form1 Localizable property to true.
2 - Set the form's Language property to "German (Germany)".
3 - Set the Label1 Text property to "German".
VB make the file -> MainForm.de-DE.resx with name: Label.Text and value: German
4 - Set the form's Language property to "Spanish (Spain)".
5 - Set the Label1 Text property to " Spanish ".
VB make the file -> resx
6 - Set the form's Language property to "French (France)".
7 - Set the Label1 Text property to "French".
VB make the file -> resx
8 - �The TextBox with the numeric value�s change when the user change the CulureInfo but not the Label1, why?It work perfect when I put �Thread.CurrentThread.CurrentUICulture = New CultureInfo("fr-FR")in the MainForm.designer.vb before InitializeComponent function and in the New function.But I want to use the ComboBox�
