I'd like to learn how I can add a bunch of strings into the AutoCompleteCustomSource property of a TextBox. Actually that doesn't seem to be possible.. What I actually want to do is to make the textbox suggest and append 7000 strings. I can do suggest and append stuff already but AutoCompleteCustomSource can contain a limited number of strings, so I have to find another way to add my strings.

I've build a list of Strings from files. The list itself is working fine (tried it by having ListBoxes and other controls loading its items from there just to make sure that this is not the issue). Now, I am using this list of strings to compare a Text in a TextBox1 while typing to determine if this TextBox1.Text already exists in the list. I am using the following code (where "s" stands for my List items):
Private Sub TextBox1_TextChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles TextBox1.TextChanged
If TextBox1.TextLength < "1" Then
Button6.Enabled = False

I am using a multililne textbox and I want to take the text typed and merge it with another string. So for example....
CoverPage = Replace(CoverPage,
Me.Note.Replace("{", "{").Replace("}", "}"), txtNote.Text)
Where Me.Note is a string that I am looking for and replacing it with the contents of txtNote.text. And then storing it all back in the string CoverPage.CoverPage is an rtf string that will holds place holders for the text I want to change.(That works) But when i update the note that may have a carriage return in it, the coverpage does not reconize the carriage returns comping from the Multiline textbox when its displayed.I have tried replaceing Enivronment.Newline with vbCr, vbCrl and whatever else I can think of. is there an issue with taking a string carriage control and tranfering it to a rtf carriage control?
Basically I have a series of lines in a textbox like this:
### = 1232, 1234, 1236, 1238, 123A, 123C ; comment here I want to show a button when the caret (cursor pipe thing) in the textbox goes is in a number so like:
... , 12|31, .... or
... , 123|1, .... etc
(the pipe being the caret)
I have written code to check if it is in a number and to get the number when the button is clicked, but it doesn't work correctly if I put the code in the selection changed event.
oh and the numbers can be upto 8 digits long and hex.

I have a list of strings. For each string in that list, I want to prepend another string. I wrote a method to do it, but I was wondering if there was something already in .NET I could use to do this. It seems like something that could be built in, but I was not able to find anything.
Here is the method I wrote:
Private Function PrependToAllInList(ByRef inputList As List(Of String), ByRef prependString As String) As List(Of String)
Dim returnList As List(Of String) = New List(Of String)
For Each inputString As String In inputList
returnList.Add(String.Format("{0}{1}", prependString, inputString))

It works, but I would rather use built in functions whenever possible.
I'm migrating from VB6 to VB.NET, in hence my questions below:
I have to write a function that returns array of strings.
How can I initiate it to empty array? I need it since I have to check if it's empty array after it returns from this function.
Is list of arrays better for this purpose? If I use a list - Is it empty when it firstly defined? How can I check it it's empty?
I'm converting a user generated list box to an array and then generating a user defined number of random strings and placing it in a textbox.The code I have works fine as it will generate the number of random strings the user wants, except sometimes a line is blank at the top of the list but is counted as a string.
