I am writing a code to search through the entire listbox items and highlight them whenever user enters text in textbox. I am looping through textbox items which are entered using a 'comma' . But the code fails to add it to selected indices when user types multiple items using comma. It works fine for single items.
Private Sub TextBox1_KeyUp(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles TextBox1.KeyUp

I am trying to write a vb2008 program that allows a user to select an airport from a combobox and then once the value has been selected it searches a comma separated text file once it has found the airport selected ( always the first column in the file) in the file it populates 8 other textboxes with the row data from the file. The idea is to select the airport and then it calls up the radio frequencies associated with the airport.I assume you have to call the data into an array and the search thorough the array until the combobox.selectedvalue = the value in the array, but i am unsure how to do this Ideally I would like to be able to the user to add data to the file thats why I used a combox, but I am having trouble trying to get the boxes to populate so first things first.

I am relatively new to VB. I was initially using fileopen, writeline, and fileclose to create, write to, and close a comma delimited file. But recently I attended a training course where the instructor mentioned that these old methods will be going away and I should try and use Streamwriter instead. I was successful in converting some of my code to StreamWriter when creating a simple text file using WriteLine.
For example: myStreamWriter.WriteLine(text). But this writes an entire line of text.
I cannot see to find any information on how to create a comma-delimited file using StreamWriter. My old code was something like this: Writeline(filenumber, field1, field2, field3, field4). How to do the same thing with StreamWriter?
I'm trying to parse csv file with VB.NET.csv files contains value like 0,"1,2,3",4 which splits in 5 instead of 3. There are many examples with other languages in Stockoverflow but I can't implement it in VB.NET.Here is my code so far but it doesn't work...
Dim t As String() = Regex.Split(str(i), ",(?=([^""]*""[^""]*"")*[^""]*$)")
I have a text box with a list of entries for example:
Reference 1
Reference 2
Reference 3

I plan to read the string back into a the textbox later using the split() method and assign each to string to an array.

I have to make a basic program that: Create a program with a simple interface that
1. Asks the user type his/her email address into a textbox.
2. When the user clicks the "Evaluate Email Address" button, one of two message boxes pops up: "That is a valid email address!" with an "Information" icon, or "That is an invalid email address!" and on a second line, "Please retype your email address.", with an "Exclamation" icon
3. To be considered valid, the email address must -include an "@" symbol, and -it must end in either ".com", ".net", or ".org" or ".edu" (I don't know how to check a string and test if its last four characters end with any of these and make it say not valid email address. I think I might have to use a case statement)
I want to put a persons National Insurance Number into a label but I want to put *** in place of the first 5 characters and then display the last 3 characters as normally.

I have created a custom logonui.exe in VB.NET and I know how to make it replace the existing logonui.exe, but I am having trouble with the functions, such as shutdown, restart and log in. I don't need to get the list of users, because there is only one user account on the system and it is not password protected. I just need it to log in to the account when the user clicks a button and to be able to shutdown when the user clicks a different button.
