VS 2005 Strea Reader/Writer Delete Line

Dec 6, 2010

I have a program that reads a text file tab delimted using OLEDb .I need to be able to allow the user to insert a user created record into the file which I can do.

The problem is I need to be able to let the user edit that record. From my understanding you can not edit or delete with OLEDB only insert So I thought I would read the file using stream reader, find the line I want to edit and just delete it, rewrite the file, then let the user insert a new record

If someone has a better way to perform this operation I am open its just the best way I could find with my limited knowledge and the reading and researching I have been doing thus far.

So I am trying to step-by step and first read the file which seems to work then find the line that would need to be deleted. So I was trying to use the
line.startswith method. I am using msgbox to see if that works before I continue but it doesnt seem to work I know my file has several lines starting with "Active" but my msgbox returns "False"

Here is the code I have so far

VS 2005 : StreamWriter Position To Line Number 9?

Sep 28, 2009

I'm testing a small program that can read & write to an rtf file. Examples I have found work fine, although I have two questions:

1)If I need to ALWAYS write to line number 9 of an existing RTF file, do I need to "read" 9 times or can I immediately position myself to line number 9. I have found character manipulation but can't seem to find what I need with positioning to a particular line number.

2)BOLD text: I have found examples where I should be able to format my text, such as

MyFile.WriteLine ""
MyFile.WriteLine Text
MyFile.WriteLine "0"

but when doing this, it does not "bold" my text, but actually prints the text exactly as shown. I'm looking for information/links that I can "bold" "Italicize" text. Code is written in VS2005.
