How do you manipulate a text file once you have opened it with Streamreader? I can get the streamreader to open the file and display it in a text/listbox but i cant do things like split and join to it.... It has no effect on the text file when viewed.
This is how i am setting up my string array:
Dim fileName As String = "C: est.txt"
Dim objReader As New System.IO.StreamReader(fileName)
how do I manipulate objReader as a string?
I am not sure if this makes sense or not,but I need to process raw text(without any encoding?) that I retrieved from a file recovery application "PhotoRec"
With an application like Notepad++ I can see all of the text I need to manipulate but with VB I seem to only get some of the text with other stuff stripped out.Here is what I am using to process the file:

I essentially add each line of text to the collection so I can read each line at a time (other processing, etc.)So, as mentioned, with the above code I get text but not all of it. With different encodings I get different versions of the text represented in "currentbyte".So, how can my .NET application read text like Notepad++ or a similar "raw" text reader app?

A1B2C3D4E5F6G7H8 then the converted sting will be H8G7F6E5D4C3B2A1.
I run into problem using: left(mystring 2) and right(mystring -2) because the string to manipulate is an input of a textbox so I fail when I try to use cross data with a StringHandling class, and how to incorporate StringHandling into my form class and without it when I try something like
Dim byte1 As String = Left(MyString, 14)I get an

I use a Java web app (app/screenshot, you'd need to sign up, but it's just a java web app), however I'd like to automate its functionality inside of a .NET application (C# or VB, doesn't matter, I'd prefer C#).
I've tried searching but unfortunately "Java web" and ".NET" and "C#" etc, don't return me anything even remotely useful. Is it possible to load the page within a control (or through some other way) within a .NET application, and thus act upon the display itself (the data flow will be encrypted, since it's https - so I don't know if I'd be able to read the data coming to and from the java application, I assume not, but being able to read the application would be nice), to be able to select areas, click, read/input numbers and text, etc. I realize this is a pretty broad question, but, it'd be very helpful if someone could offer some advice/insight into this problem.
edit to add: I guess a better question would have been either "Ways to interact with a java web-start app with windows apis?" or "Possible to contain a java web-start app within a .NET app, and interact directly with components of the web app". I'm also wondering if it will be possible to load it into a browser in a form in .NET, although I assume that it would just launch web-start taking it out of the forms control.
I am fairly certain that the error is on my calling the SQL database, but just checking if there is something obvious that I am missing.
