I was able to solve the problem using Standard TextBox control Vs. RichTextBox Control which for some reason makes ERRORS / Problems with GetLineFromCharIndex and Counts the Incorrect Line

Here is...

I have word wrap as False and I get different results from GetLinefromCharIndex and Lines.Length.

What else can I do?

Array in a Textbox? I have always had the Text In a RichTextbox. Then I Search it. Ultimately I'm doing the same thing. I'm just making it possible to see what Lines I have been copying by saving...

Now... This Runs Extreamly Fast, But it picks Either the Incorrect lines or something else (Not sure)

RichTextBox2.Clear()
RichTextBox2.Text = String.Empty
...

Yes and No. Basicly Highlighting Text is not the answer, but Finding the Text is the Answer. I don't need to highlight. I just need to know the Line Position of the Text String and for each found...

How do I find a Known String of Text "M6" from a Loaded Text Document that is in RichTextBox1, then get it to output the Lines that these strings (all of them) are found to a ListBox. Notepad can do...

Addressof Match " does not fit, Match is an Error. What should this Match be?

All I want is to speed up the Text Find and Save to String Process. I have tried 4 different Methods. All of which...

What about using the Find Feature? I now that Document.Find(TextBox1.Text) works (for what character)... but I don't know how to apply it to find what Line, or how to get it to start at the line it...

I changed to this

Dim FileLines() As String = File.ReadAllLines(Document.Text)
Dim SavedLines As New ArrayList
For I As Integer = 0 To LineCount - 1
If...

Maybe its because this is how I wrote it?
Dim curLine As String
Dim oldLine As String
Dim bFlag As Boolean
Dim SavedLines As New Stack
Dim fs = New...

This is about as simple of code as I could muster together that will show the problem.

How do we fix this from Taking 10 minutes to find strings of Text that I know that a standard CTRL+F can...

Now " New StreamReader(fs) "is the OverLoad Resolution

I already have this... but I still have an error at " Dim ds As New StreamReader(fs) "

What would cause this to be a problem?

I got it ro Re-Loop, but it overwrites Line 1 " This Document..." and String.Join doesn't let me add "TEXT".

The Write Isn't really the Slowdown though. It is the ReadLines. But this will help...

String.Join works very fast, but after it reads its first set of lines it doesn't re-Loop. So I can get the first 75 characters.. then when Textbox1.Text Appears it copies 20 lines before that to 20...

Dim d as new StreamReader(fs)
Causes "Overload Resolution Failed , New cannot be called - Object to String"

--- So I cannot test this feature and I'm not sure what this Error Means.

I'm a little confused? Exactly how is this going to stop the 10000 ReReads? Won't it still ReRead?

I have been trying to process some text about 10000 lines to upwards of 26000 lines of text. I wrote a program to search for text strings and copy the lines around them if they are found.

It...
