I don't know exactly how to load a stream of text then edit the stream (instead of loading it into a textbox for manual editing), and save (overwrite/append) it to the original file.
I've looked on Google, but they're not exactly what I'm looking for.

View 1 RepliesI'm working on a licensing system for my application. I'd like to put all licensing information (licensee name, expiration date, and enabled features) into an object, encrypt that object with a private key, then represent the encrypted data as a single text string which I can send via email to my customers.
I've managed to get the encrypted data into a byte stream, but I don't know how to convert that byte stream into a text value -- something that contains no control characters or whitespace. Can anyone offer advice on how to do that? I've been researching the Encoding class, but I can't find a text-only encoding.

P.s: I both use C# and VB.NET so,
in an winForm app in VS2010 win 7 compiling to x86, I try to do what Alvas.Audio seems to work. See (c# ex: [URL] for reference.
Dim data() As Byte = wr.ReadData(second * i, second)
The result give me data.length()=0. I do not have any exception, I can read format from it and whatever reader I use I got this problem.EDIT : After some tests, it seems like the uncompressed file I create in the first step (in PCM format, with .wav extension) can not be recognized by the Alvas.audio library for the second step. I must miss something around Audio file markups or something alike.
Here is the code that might be the source (basically this is step 1):
Dim functOut As String = String.Empty
Dim wr As Alvas.Audio.IAudioReader = Nothing
Dim fs As IO.FileStream = Nothing

I'm working on a piece of code at the moment that uses an older style DataGrid to allow the user to enter information into the table. It already has an add and delete button. Currently the user enters information into 3 textboxes that are in the footer, and the other rows use labels to display the information.
Essentially what I am wanting to do is take the line that the user has clicked the edit button on, and move the text from there in to the footer (deleteing the row that it was displayed on) so the user can make changes and then click the add button again. At the moment I have tried using FindControls to find the textbox and setting the text that way but it doesnt like it.
I have a pretty simple question I was hoping someone could help me with, there are two text files - first is C:Test1.txt and the other C:Test2.txt.C:Test1.txt data consists of, the column is separated by a space (" ")

I have a system where I would like to show a warning to a user if there try and edit a record that is currently been edited. If this is the case the user will not be able to save the record but only view it.I have an idea of using some kind of class to monitor the activity of records been edited etc but this seams a little over kill. My other concern is that what if the browser crashes or there shut their computer down on how this will effect the state of the page.
Another thought was to use last updated time stamp but this also looks a no go because the way records are been updated? how I could implement something like this. No code is necessary.based on the comments I have added these additional details.database is SQL server 2008 asp.net 3.5 one record could be many parts of the database for instance, the booking table session table and a row in the interrupter table.the user will look at a list of sessions that need booking select a booking and fill out a booking form to make the booking. Want to stop is someone else trying to do the same booking at the same time or while someone else is doing the booking.
