I was just wondering is there an easy way to replace a line in a string where I don't know what line it will be and I don't know what will be on that line apart from the first three characters which will always be:
To:
And that shouldnt be anywhere else in the string.
This string will be the contents of an email (read in via an EML file) I then need to change the line that says 'To: <someones@email.address> to a series of addresses then save them eml again.
I have read then entire email in and stored it in a string and can save again just struggling on the replacement of that line.

I'm adding some content within a long concatenated string (it's horrible, I know).
I have to display 3 columns of data from a datatable and my code looks like this.
If Not IsNothing(MyBase.EligibilityQuestions) Then
Dim sw As System.IO.StringWriter
For Each row As DataRow In MyBase.EligibilityQuestions.Rows
[Code]....
My problem is I end up with text that overflows to a new line and doesn't line up with the text from the column it belongs, I'm writing this for a DynamicPDF so I can't insert HTML, and I'm trying to get this to look like a table (all the columns lined up).

I am using this code:
[Code]...
It even indicates if the string I'm seeking is in the middle of a line. But what I would like is for the routine to highlight the line that that string is in and ensure visible. I can do that with another routine that uses an integer, but then the whole string(line) has to be the searchString. I've tried combining the two and even calling a Private Sub but with no success:(What is the best way to do this? Also, how do you get around doing it when the searchWord in in several lines?

I have a bunch of object variables which are all initialised in their declarations such that:
Private _myObject As New ThisObject("SomeString")
where ThisObject is one of a number of object types, but all are initialised using a string.
I would like to use the Visual Studio Find/Replace dialog box to search for "As New" then replace everything from "As New" to the first set of speech marks with some text such that:
EDIT
My original example could be solved using other methods. This example is more representative of the actual problem:
Private _myObjectA As New ThisObjectA("SomeString")
Private _myObjectLongName As New ThisObjectLongName("SomeString")

I have not had much time to go threw my code properly as this is some urgency. I need to remove line 1 from a textfile if it contains a string but its not working.I have 500 files and not going to do this manually.
Code:
Private Sub btnRemove_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnRemove.Click
If String.IsNullOrEmpty(txtDirectory.Text) Then
OpenFolderDialogDirectory()
[code]....
I also feel the function is very pointless sime i am opening the file twice.

For example I have a strint containing text with more than 1 line. For example:
"Hello How Are You"
I want to read a specific line of the string, if I choose to read line 1 of the string in a messagebox then the word "How" will probably pop up.

I'm new here, but have been in and out for a while. Past threads have been helping me along thus far.
I'm currently developing an app which essentially needs a way for me to search in a text box or file for a specific string, and extract the line on which that string appears on. It will be unique, and the syntax is the same on each line. It has basically 2 ID numbers, and is laid out like this:
123456|123456
So, I'd need to search for the first part before the |, and then get the line so I can get the bit after the |, which is the important bit for me.
