Vb is not my language of choice , but I have to do this for school and I'm not having a very easy time with VB's documentation.I'm just creating a very simple console application that accepts user input: degrees in Celsius, and converts it into Fahrenheit. I want to make sure that if the user just hits enter without entering the degrees in Celsius, then an if else statement will catch and write to enter Celsius again.Here's what I've tried:
[Code]...
I have a procedure at the end of my console application that ask the user to either hit enter to end the program, or type s to perform another search. The issue I'm having is no matter what the user types in the program end. What I would like to happen is if the user types s, then the program starts over and lets the user perform another search. The program is procedural and I need to find a way to start back off at the top of the program which ask the user to type a name to search.

I have a problem with reading and writing to the console from a windows form application.
I am running visual studios 2010 and I am coding in visual basic.The current code that I have is as follows:
Declare Function AttachConsole Lib "kernel32.dll" (ByVal dwProcessId As Int32) As Boolean
Declare Function FreeConsole Lib "kernel32.dll" () As Boolean
System.Console.Write("abc")
Dim test as string = Console.ReadLine()
System.Console.Clear()
ect

Just wondering if there is anyway to read each line of text that is output from a console application?
Basically I want to use PSEXEC through a vb.net GUI application and I would like to be able to read any error codes that may occur from the command line.
I was wondering it's it possible to read all the text being displayed from a console/terminal/cmd application (What ever you want to call it).
I would then want to echo that text in a text box.
I am trying to make a program using Visual Basic that will allow the user to add links to web pages (such as www.google.ca) to a list in the program and make it so that they do not dissapear once the program is closed.
So to get into more detail, I have a text box, a listview, and a button. When the user types a link into the text box it needs to be put into an array (called "addlink") and then when the user presses the button, the link is typed into the listview as an object.
Then if the user clicks on that object in the listview, it will open up the browser using the WebBrowser command. How do I set the text in the textbox to an array once the button is clicked?

View 1 RepliesTrying to imitate a Messagebox - in that, a sub will not continue until the user "deals with" the pop up.
For example, in a sub, I want a Form to pop up, and ask a user a question, and give them 3 options. I want to make it so the user must click an option, and then the sub that called it can carry on it's way.
I believe I need a function to make this happen.

View 10 RepliesBasically i am creating a console application that will create and store client information as a .txt file it is going okay but i have come across a slight hick up i want to use something on the lines of this .....
dim lastname as string
Do Until Integer.TryParse(Console.ReadLine(), LastName) = False
Console.WriteLine("Invalid input, Please try again")
Console.Write("LastName:-")
[code].....
this works fine to trap out numbers from letters but the problem i am getting is when the program calls uppon LastName it is recording 0 and wanted to know if there is a way of getting past this ..... so basically i need a way to allow letter but not numbers and symbols and then dispay a pernolised error message but at the same time use Stream writer to save was the answer is in a .txt file.
For a class assignment I created an application that takes grades from the user via input box and adds them to an array called grades. Here is some of the code.
vb.net
Option Strict On
Option Explicit On
Option Infer Off
[Code]...
My problem is that the variable x is an integer and the user input from the InputBox is a string so I get the error: "Option Strict On disallows implicit conversion from 'String' to 'Integer'.I've already submitted this assignment with out the first three lines of code (which allows the code to run flawlessly), but I would like to know how to get around the error while still using the Option Strict On parameter. I am aware of the ToString method but I am not sure of how to use it here or even if it will work here. I've tried to use in a few variations but none worked.
I am trying to create a function to remove dirty words from user input text and want to replace those dirty words with four ****. In my scenario , i have list of dirty words where i would iterate the input user text and want to replace. Say for example.,
Dim InputTxt As String = "hi bush how are you.... $hit and @ss"
Dim OutPut As String = " hi **** how are you... **** and ****";
Problem: It works fine to replace some word like " bush" however fails in the below function doesn't replace "$hit" and "@ss".
Note: I do not want to use string.Replace because it doesn't have word boundary in the sentence..
Public Function pReplaceWords(ByVal dirtyWord As String, ByVal inputText As String, ByVal options As RegexOptions) As String
Try
