However what is displayed is each character from the source code, rather than the line. I am making the client log into a website, and the needed value from the source code is then parsed, so I need to use the WebBrowser type to get the source code.

I am using VB.net 2010 and SQL client server.I have to make a Weekly Report Manager that stores an Trainees' weekly activity, which would probably be in a paragraph form.I think I can use Textbox (multilined) or Richtextbox for this.But When I tried to store and read the stored data it is not multilined.
Example:
INPUT in textbox/richtextbox: I am a good trainee inserted it in database as textbox.text or richtextbox.text and the result will be:
I ama goodtrainee
So if I retrieve the data it displays a single lined text.How can I do it properly?

This is my first time writeing a program and i am stuck. i am just looking for were i should go next. i can't figure out how to write in code for the days in the getDay function.
Write a program that computes the cost of a long-distance call. The cost of the call is determined according to the following rate schedule:
a. Any call started between 7:00 A.M. and 9:00 P.M., Monday through Friday, is billed at a rate of $0.30 per minute.
b. Any call started before 7:00 A.M. or after 9:00 P.M., Monday through Friday, is billed at a rate of $0.15 per minute.
c. Any call started on a Saturday or Sunday is billed at a rate of $0.10 per minute.
The inputs will consist of (1) the day of the week, (2) the start/end time of the call, and (3) the length of the call in minutes. The output will be the cost of the call. Input will come from the user and outputs will be displayed via the console window.

I am databinding my gridview in VB code behind. Because of this I know I can not refer to the NewValues when text is entered into one of the edit boxes. I need to retrieve the value of a column in the RowUpdating event.I have tried to do this in a multide of ways, but each of my changes ends up breaking something else.None of these three methods is working....
Dim DT34 As String = DirectCast(GridView4.Rows.FindControl("Textbox1"), TextBox).Text
Dim TB1 As Label = GridView4.Rows(e.NewEditIndex).Cells(0).FindControl("Label1")
Dim tb1 As TextBox = GridView4.Rows(e.RowIndex).Cells(0).FindControl("TextBox1")
Dim IDVal As String = tb1.Text
In the following code, I am believe it is finding the control but it is not returning the value that was entered into the textbox.
Dim tb As TextBox = DirectCast(GRD4.Rows(index1).FindControl("TextBox1"), TextBox)
updateDescription = tb.Text
My field has been converted to a Template field in the Gridview instead of Boundfield.

VB.NET 2008. How could I make a new line inside the ToString() Function that VB already have. How to do like a .WriteLine() but inside the ToString() function. In my case, this inside of a class of course. I don't know if you get me. All I want to do is to show a fraction in the normal way not using the slash(/). Showing the numerator on top of a line, and below it the denominator. This inside the VB pre-made ToString() function.
This is what I've tried;
Public Overrides Function ToString() As String
Return Me.numerator & "/" & Me.denominator
End Function
Output example: 2/3
But this is not what I want.
