I have designed a form with a text box on it, and a command button underneath. The idea is to run this as a sort of stiky notes section.
I want the text box to read rich text into the textbox (C:\\stickynotes.rtf")
Then i have a command button underneath which i want to save the content of the rich text box to the rtf file (C:\\stickynotes.rtf). This is so that the user can edit and ammend information.
here is some code i have so far
Dim fileReader As System.IO.StreamReader
fileReader = My.Computer.FileSystem.OpenTextFileReader("C:\\stickynotes.rtf")
So far what i have is a button and a text box and when you press the button it my.computer.filesystem.readalltext(from this file as string) but what i want it to do is to read all the text in that file minus whatever is in parenthesis so like lets say the file has saved into it, hi my name is bob but my realname is (jeorge) that when you press the button it reads and shows everything in the file minus jeorge which is in parenthesis

Is there any Windows API Routine to read something like that?Or could you point me an URL where something is implemented?I don't want a procedure to read the file line by line and comparing them with Line Input because blank spaces, empty lines and comments starting with " // " may appear too, and I don't want to take them into account, but also I need to save changes to the file, but only to the modified section, without having to read the whole file, and re-write it completely.
Binary access can't work, because I don't know what's the size of each "section", since the number of elements into it can change.
I need something like the "ReadINI" Windows API Procedure, but allowing me to read the "[XXX]" sections headers, and also the "<XXX>" file title header.
